Description
本発明は、測定機器を断熱保護するために測定機器が収容される測定機器収容用断熱容器に関する。 The present invention relates to an insulated container for housing measuring equipment, which houses measuring equipment to provide thermal protection for the measuring equipment.
従来、測定機器を断熱保護するために測定機器が収容される断熱容器として特許文献１に開示されている断熱容器がある。この断熱容器は、センサー及びセンサー制御回路が二重壁構造の真空断熱容器に収容され、真空断熱容器が耐圧外囲器に収容されていると共に、真空断熱容器の開口側に耐熱樹脂キャップが設けられ、耐熱樹脂キャップを貫通するようにしてセンサー制御回路の接続ケーブルが外部に引き出される構造になっている（特許文献１の図１参照）。更に、特許文献１には真空断熱容器の開口側に断熱シール材と耐熱樹脂キャップが設けられ、断熱シール材と耐熱樹脂キャップを貫通するようにして接続ケーブルが外部に引き出される変形例が開示されている（特許文献１の図２参照）。 Patent Document 1 discloses a conventional insulated container for housing measuring equipment to provide thermal protection. This insulated container houses a sensor and sensor control circuit in a double-walled vacuum insulated container, which is housed in a pressure-resistant outer envelope. A heat-resistant resin cap is provided on the opening side of the vacuum insulated container, and the connection cable for the sensor control circuit is pulled out to the outside, penetrating the heat-resistant resin cap (see Figure 1 of Patent Document 1). Patent Document 1 also discloses a modified version in which an insulating sealant and a heat-resistant resin cap are provided on the opening side of the vacuum insulated container, and the connection cable is pulled out to the outside, penetrating the insulating sealant and heat-resistant resin cap (see Figure 2 of Patent Document 1).
ところで、特許文献１に記載の断熱容器は、センサーのような測定機器の接続ケーブルを断熱シール材と耐熱樹脂キャップを貫通させて内外に連通する構造になっており、接続ケーブルの周辺における断熱性は確保されている。しかしながら、接続ケーブルを介した内外の伝熱を抑制することはできないため、容器内外の断熱保護が十分に図られているものとは言い難い。 The insulated container described in Patent Document 1 is designed so that the connection cable of a measuring device such as a sensor passes through an insulating sealant and a heat-resistant resin cap to communicate with the inside and outside, ensuring thermal insulation around the connection cable. However, because it is not possible to suppress heat transfer between the inside and outside of the container via the connection cable, it is difficult to say that the container provides sufficient thermal protection inside and outside the container.
本発明は上記課題に鑑み提案するものであって、接続ケーブルを介した容器内外の伝熱を抑制し、収容される測定機器の断熱保護を確実に図ることができる測定機器収容用断熱容器を提供することを目的とする。 The present invention was proposed in light of the above-mentioned problems, and aims to provide an insulated container for housing measuring equipment that can suppress heat transfer inside and outside the container via the connection cable and ensure thermal protection of the housed measuring equipment.
本発明の測定機器収容用断熱容器は、測定機器が収容される有底筒状の真空断熱容器部と、前記真空断熱容器部の開口側に設けられる第１の耐熱樹脂キャップと、前記第１の耐熱樹脂キャップと前記真空断熱容器の軸方向に離間して配置される第２の耐熱樹脂キャップと、前記第１の耐熱樹脂キャップと前記第２の耐熱樹脂キャップとの間の空間に封入される潜熱蓄熱材とを備え、前記第１の耐熱樹脂キャップと前記第２の耐熱樹脂キャップと前記潜熱蓄熱材を貫通するように配線される前記測定機器の接続ケーブルの外周に、前記潜熱蓄熱材が接触するように設けられることを特徴とする。
これによれば、潜熱蓄熱材を貫通するように配線される測定機器の接続ケーブルの外周に潜熱蓄熱材を接触させることにより、接続ケーブルを介した容器内外の伝熱を抑制し、収容される測定機器の断熱保護を確実に図ることができる。また、外部と熱の流入・流出量が高くなる断熱容器の開口側に、第１の耐熱樹脂キャップと第２の耐熱樹脂キャップとその間の潜熱蓄熱材による三重構造を設けることにより、断熱容器の断熱性をより高めることができる。
The insulated container for accommodating measuring equipment of the present invention comprises a bottomed, cylindrical vacuum insulated container section in which the measuring equipment is accommodated, a first heat-resistant resin cap provided on the opening side of the vacuum insulated container section, a second heat-resistant resin cap arranged at a distance from the first heat-resistant resin cap in the axial direction of the vacuum insulated container, and a latent heat storage material sealed in the space between the first heat-resistant resin cap and the second heat-resistant resin cap, and is characterized in that the latent heat storage material is arranged so as to be in contact with the outer periphery of the connecting cable of the measuring equipment which is wired to pass through the first heat-resistant resin cap, the second heat-resistant resin cap, and the latent heat storage material.
According to this, by contacting the latent heat storage material with the outer periphery of the connection cable of the measuring instrument that is wired so as to pass through the latent heat storage material, heat transfer inside and outside the container via the connection cable can be suppressed, and thermal protection of the contained measuring instrument can be reliably achieved. Furthermore, by providing a triple structure consisting of a first heat-resistant resin cap, a second heat-resistant resin cap, and a latent heat storage material between them on the opening side of the insulated container where the amount of heat inflow and outflow from the outside is high, the thermal insulation of the insulated container can be further improved.
本発明の測定機器収容用断熱容器は、前記第１の耐熱樹脂キャップと前記第２の耐熱樹脂キャップとの間に短筒状のスペーサが設けられ、前記第１の耐熱樹脂キャップと前記第２の耐熱樹脂キャップと前記スペーサで囲まれる封入空間に前記潜熱蓄熱材が封入されると共に、前記測定機器が収容される有底筒状のインナーケースの開口側の端部が、前記スペーサの外周側に設けられるシール材で前記真空断熱容器部の内周壁に向かって押圧付勢されて前記インナーケースが着脱自在に固定されていることを特徴とする。
これによれば、測定機器が収容される有底筒状のインナーケースの開口側の端部をスペーサの外周側のシール材で真空断熱容器部の内周壁に向かって押圧付勢してインナーケースを固定することにより、真空断熱容器部の内部にインナーケースを簡単に着脱自在に固定することができる。従って、インナーケースやこれに収容される測定機器のメンテナンスや取替を容易に行うことができる。また、インナーケースの開口側の端部をシール材で押圧付勢することにより、測定機器が収容されるインナーケースの内部への水の浸入を確実に防止することができる。
The insulated container for accommodating measuring equipment of the present invention is characterized in that a short cylindrical spacer is provided between the first heat-resistant resin cap and the second heat-resistant resin cap, the latent heat storage material is sealed in the enclosed space surrounded by the first heat-resistant resin cap, the second heat-resistant resin cap and the spacer, and the open end of the bottomed cylindrical inner case in which the measuring equipment is accommodated is pressed and urged toward the inner wall of the vacuum insulated container section by a sealing material provided on the outer periphery of the spacer, so that the inner case is fixed in a freely attachable and detachable manner.
According to this, the open end of the bottomed cylindrical inner case that houses the measuring instrument is pressed and urged toward the inner peripheral wall of the vacuum insulated container with the sealing material on the outer periphery of the spacer to fix the inner case, thereby making it possible to easily and detachably fix the inner case inside the vacuum insulated container. Therefore, maintenance and replacement of the inner case and the measuring instrument housed therein can be easily performed. Furthermore, by pressing and urging the open end of the inner case with the sealing material, it is possible to reliably prevent water from entering the inner case that houses the measuring instrument.
本発明の測定機器収容用断熱容器は、前記第１の耐熱樹脂キャップよりも外側に配置される前記第２の耐熱樹脂キャップの外面に沿うように補強リングが設けられ、前記補強リングと前記第２の耐熱樹脂キャップとが、前記スペーサに対してバネクリップで前記真空断熱容器部の底側に向かって押圧付勢されるようにして取り付けられていることを特徴とする。
これによれば、第２の耐熱樹脂キャップをバネクリップでスペーサに押圧付勢することにより、第２の耐熱樹脂キャップとスペーサとの当接領域の密着性を高め、断熱容器の断熱性をより高めることができる。また、補強リングを介して第２の耐熱樹脂キャップをバネクリップでスペーサに押圧付勢することにより、第２の耐熱樹脂キャップの変形を防止することができる。
The insulated container for storing measuring equipment of the present invention is characterized in that a reinforcing ring is provided along the outer surface of the second heat-resistant resin cap, which is positioned outside the first heat-resistant resin cap, and the reinforcing ring and the second heat-resistant resin cap are attached to the spacer by a spring clip so that they are pressed against the bottom side of the vacuum insulated container portion.
According to this, by pressing and urging the second heat-resistant resin cap against the spacer with the spring clip, the adhesion of the contact area between the second heat-resistant resin cap and the spacer can be improved, and the thermal insulation of the insulated container can be further improved. Also, by pressing and urging the second heat-resistant resin cap against the spacer with the spring clip via the reinforcing ring, deformation of the second heat-resistant resin cap can be prevented.
本発明の測定機器収容用断熱容器は、前記第１の耐熱樹脂キャップと前記第２の耐熱樹脂キャップとが電磁波透過性材料で形成されていると共に、前記潜熱蓄熱材が相変化の前後で絶縁性を維持する材料で形成されていることを特徴とする。
これによれば、第１の耐熱樹脂キャップと第２の耐熱樹脂キャップとその間の潜熱蓄熱材が設けられる断熱容器の開口側で電波を常時透過させることができ、断熱容器の内部に収容される測定機器を外部から無線通信で制御することが可能となる。
The insulated container for storing measuring equipment of the present invention is characterized in that the first heat-resistant resin cap and the second heat-resistant resin cap are formed of an electromagnetic wave-transmitting material, and the latent heat storage material is formed of a material that maintains its insulating properties before and after a phase change.
This allows radio waves to constantly pass through the opening side of the insulated container, where the first heat-resistant resin cap, the second heat-resistant resin cap, and the latent heat storage material between them are provided, making it possible to control the measuring equipment housed inside the insulated container from the outside via wireless communication.
本発明の測定機器収容用断熱容器は、前記第１の耐熱樹脂キャップと前記第２の耐熱樹脂キャップとの間に短筒状のスペーサが設けられ、前記第１の耐熱樹脂キャップと前記第２の耐熱樹脂キャップと前記スペーサで囲まれる封入空間に前記潜熱蓄熱材が封入され、前記潜熱蓄熱材がゲル状有機系潜熱蓄熱材で構成され、前記ゲル状有機系潜熱蓄熱材に前記接続ケーブルを直接貫通させ、前記ゲル状有機系潜熱蓄熱材が前記接続ケーブルの外周に固体－液体相転移の前後で常時直接接触するように設けられることを特徴とする。
これによれば、ゲル状有機系潜熱蓄熱材と接続ケーブルの外周との接触性を固体－液体相転移の前後で確実に確保することができ、伝熱抑制性をより確実に高めることができる。
The insulated container for accommodating measuring equipment of the present invention is characterized in that a short cylindrical spacer is provided between the first heat-resistant resin cap and the second heat-resistant resin cap, the latent heat storage material is sealed in an enclosed space surrounded by the first heat-resistant resin cap, the second heat-resistant resin cap, and the spacer, the latent heat storage material is composed of a gel-like organic latent heat storage material, the connection cable is directly passed through the gel-like organic latent heat storage material, and the gel-like organic latent heat storage material is arranged so as to be in direct contact with the outer periphery of the connection cable at all times before and after a solid-liquid phase transition.
This ensures reliable contact between the gel organic latent heat storage material and the outer periphery of the connection cable before and after the solid-liquid phase transition, thereby more reliably enhancing the heat transfer suppression.
本発明の測定機器収容用断熱容器は、前記第１の耐熱樹脂キャップと前記第２の耐熱樹脂キャップとの間に短筒状のスペーサが設けられ、前記第１の耐熱樹脂キャップと前記第２の耐熱樹脂キャップと前記スペーサで囲まれる封入空間に前記潜熱蓄熱材が封入され、前記潜熱蓄熱材が、有機系潜熱蓄熱材が封入されたマイクロカプセルの集合体で構成され、前記マイクロカプセルの集合体に前記接続ケーブルを貫通させ、前記マイクロカプセルの集合体が前記接続ケーブルの外周に常時接触するように設けられることを特徴とする。
これによれば、潜熱蓄熱材に相当する有機系潜熱蓄熱材が封入されたマイクロカプセルの集合体と接続ケーブルの外周との接触性を固体－液体相転移の前後で確実に確保することができ、伝熱抑制性をより確実に高めることができる。

本発明の測定機器収容用断熱容器によれば、接続ケーブルを介した容器内外の伝熱を抑制し、収容される測定機器の断熱保護を確実に図ることができる。 The insulated container for housing measuring equipment of the present invention suppresses heat transfer inside and outside the container via the connection cable, ensuring reliable thermal protection of the housed measuring equipment.
〔実施形態の測定機器収容用断熱容器〕
本発明による実施形態の測定機器収容用断熱容器１は、図１～図４に示すように、測定機器１０が収容される有底筒状の真空断熱容器部２と、真空断熱容器２の開口側に設けられる第１の耐熱樹脂キャップ３と、第１の耐熱樹脂キャップ３と真空断熱容器２の軸方向に離間して配置される第２の耐熱樹脂キャップ４と、第１の耐熱樹脂キャップ３と第２の耐熱樹脂キャップ４との間の封入空間Ｓに封入される潜熱蓄熱材５と、第１の耐熱樹脂キャップ３と第２の耐熱樹脂キャップ４との間に設けられる短筒状のスペーサ６と、真空断熱容器部２の内部で測定機器１０が収容される有底筒状のインナーケース７を備える。
[Insulating container for accommodating measuring equipment according to the embodiment]
As shown in Figures 1 to 4, an insulated container 1 for accommodating a measuring device according to an embodiment of the present invention comprises a bottomed, cylindrical vacuum insulated container section 2 in which a measuring device 10 is accommodated, a first heat-resistant resin cap 3 provided on the opening side of the vacuum insulated container 2, a second heat-resistant resin cap 4 arranged at a distance from the first heat-resistant resin cap 3 in the axial direction of the vacuum insulated container 2, a latent heat storage material 5 sealed in an enclosed space S between the first heat-resistant resin cap 3 and the second heat-resistant resin cap 4, a short cylindrical spacer 6 provided between the first heat-resistant resin cap 3 and the second heat-resistant resin cap 4, and a bottomed, cylindrical inner case 7 in which the measuring device 10 is accommodated inside the vacuum insulated container section 2.
真空断熱容器部２は、二重壁構造の内部に減圧空間ＤＳが設けられた有底筒容器の形状で形成されており、外側底板２１と、外側底板２１の周縁から起立するように固定された外周壁２２と、内側底板２３と、内側底板２３の周縁から起立するように固定された内周壁２４を有する。外側底板２１と内側底板２３、外周壁２２と内周壁２４はそれぞれ離間配置され、外側底板２１と内側底板２３との間、及び外周壁２２と内周壁２４との間に減圧空間ＤＳが設けられている。外周壁２２の先端部は内方に湾曲形成されて内周壁２４の先端部に当接され、外周壁２２の先端部と内周壁２４の先端部とが溶接等で固定されて、減圧空間ＤＳが閉塞されている。 The vacuum insulated container section 2 is formed in the shape of a bottomed cylindrical container with a double-wall structure and a reduced pressure space DS inside. It has an outer bottom plate 21, an outer peripheral wall 22 fixed to stand up from the periphery of the outer bottom plate 21, an inner bottom plate 23, and an inner peripheral wall 24 fixed to stand up from the periphery of the inner bottom plate 23. The outer bottom plate 21 and the inner bottom plate 23, and the outer peripheral wall 22 and the inner peripheral wall 24 are spaced apart from each other, and a reduced pressure space DS is defined between the outer bottom plate 21 and the inner bottom plate 23, and between the outer peripheral wall 22 and the inner peripheral wall 24. The tip of the outer peripheral wall 22 is curved inward and abuts against the tip of the inner peripheral wall 24, and the tip of the outer peripheral wall 22 and the tip of the inner peripheral wall 24 are fixed together by welding or the like, thereby closing the reduced pressure space DS.
有底筒状の真空断熱容器部２の内部には、有底筒状のインナーケース７が開口側を揃えるようにして配設されている。インナーケース７の周壁７１は真空断熱容器部２の外周壁２２及び内周壁２４よりも長さが短く形成されており、周壁７１の先端部は、真空断熱容器部２の内部に配置されている。 A cylindrical inner case 7 with a bottom is disposed inside the cylindrical vacuum insulated container 2, with the open sides aligned. The peripheral wall 71 of the inner case 7 is shorter than the outer peripheral wall 22 and inner peripheral wall 24 of the vacuum insulated container 2, and the tip of the peripheral wall 71 is located inside the vacuum insulated container 2.
短筒状のスペーサ６の外周面は、真空断熱容器２の底側の部分がインナーケース７の周壁７１の内側に挿入され、外側に突出した段差面で形成された真空断熱容器部２の開口側の部分が真空断熱容器部２の内周壁２４の内周面に接触するように配置されている。スペーサ６におけるインナーケース７の周壁７１の内側に挿入される部分の外周面にはリング状の凹溝６１が形成されており、凹溝６１にリング状のシール材６２が嵌め込まれている。図示例では、真空断熱容器部２の軸方向に離間した複数箇所の２か所に凹溝６１が形成され、それぞれの凹溝６１にシール材６２が嵌め込まれている。 The outer peripheral surface of the short cylindrical spacer 6 is positioned so that the bottom portion of the vacuum insulated container 2 is inserted inside the peripheral wall 71 of the inner case 7, and the portion of the opening side of the vacuum insulated container 2 formed by the outwardly protruding stepped surface contacts the inner peripheral surface of the inner peripheral wall 24 of the vacuum insulated container 2. A ring-shaped groove 61 is formed on the outer peripheral surface of the portion of the spacer 6 that is inserted inside the peripheral wall 71 of the inner case 7, and a ring-shaped sealant 62 is fitted into the groove 61. In the illustrated example, grooves 61 are formed in two of multiple locations spaced apart in the axial direction of the vacuum insulated container 2, and sealant 62 is fitted into each groove 61.
インナーケース７の開口側の端部、即ち周壁７１の先端部は、スペーサ６の外周側に設けられたシール材６２で真空断熱容器部２の内周壁２４に向かって押圧付勢されており、この押圧付勢によってインナーケース７が真空断熱容器部２の内部に着脱自在に固定されている。また、インナーケース７の周壁７１の先端が段差に当接して位置決めされたスペーサ６は、この押圧付勢により、真空断熱容器部２に対して位置決めされて固定される。 The open end of the inner case 7, i.e., the tip of the peripheral wall 71, is pressed toward the inner peripheral wall 24 of the vacuum insulated container section 2 by a sealing material 62 attached to the outer periphery of the spacer 6, and this pressing force detachably fixes the inner case 7 inside the vacuum insulated container section 2. Furthermore, the spacer 6, which is positioned when the tip of the peripheral wall 71 of the inner case 7 abuts against the step, is positioned and fixed relative to the vacuum insulated container section 2 by this pressing force.
スペーサ６の内端側には、断面視Ｌ字状の周溝６３がスペーサ６の内周寄りに形成されており、図示例で略平板蓋状に形成された第１の耐熱樹脂キャップ３が周溝６３に嵌着するようにして設けられている。これにより、第１の耐熱樹脂キャップ３は、インナーケース７の内部に配置されて、真空断熱容器２の開口側で真空断熱容器部２の内部に配設される。また、スペーサ６の外端近傍の外周には切欠が形成され、この切欠に嵌合されるようにしてシール材６４が設けられている。シール材６４は、真空断熱容器部２の先端とスペーサ６に密接するように配置され、真空断熱容器部２とスペーサ６との間の隙間から真空断熱容器部２の内側に水が浸入することをより確実に防止している。 A circumferential groove 63, L-shaped in cross section, is formed near the inner periphery of the spacer 6 at its inner end, and a first heat-resistant resin cap 3, which in the illustrated example is formed in the shape of a roughly flat lid, is fitted into the circumferential groove 63. As a result, the first heat-resistant resin cap 3 is positioned inside the inner case 7 and is disposed inside the vacuum insulated container portion 2 on the opening side of the vacuum insulated container 2. A notch is formed on the outer periphery near the outer end of the spacer 6, and a sealant 64 is provided to fit into this notch. The sealant 64 is positioned so as to be in close contact with the tip of the vacuum insulated container portion 2 and the spacer 6, more reliably preventing water from entering the inside of the vacuum insulated container portion 2 through the gap between the vacuum insulated container portion 2 and the spacer 6.
スペーサ６の外端面には、図示例で略平板蓋状に形成され且つ第１の耐熱樹脂キャップ３よりも面積を大きく形成された第２の耐熱樹脂キャップ４が当接されている。第２の耐熱樹脂キャップ４は、第１の耐熱樹脂キャップ３よりも外側に配置され、その内側の面がスペーサ６の外端面に当接するようして固定されている。この当接により、測定機器収容用断熱容器１の内外の断熱性と防水性が高められている。 A second heat-resistant resin cap 4, which in the illustrated example is formed in a generally flat lid shape and has a larger surface area than the first heat-resistant resin cap 3, is abutted against the outer end surface of the spacer 6. The second heat-resistant resin cap 4 is positioned further outboard than the first heat-resistant resin cap 3 and is fixed so that its inner surface abuts against the outer end surface of the spacer 6. This abutment improves the thermal insulation and waterproofing of the inside and outside of the insulated container for housing measuring equipment 1.
本例では、第２の耐熱樹脂キャップの外面に沿うように補強リング８が設けられていると共に、真空断熱容器部２の外周壁２２の周方向の複数箇所にバネクリップ９１と、バネクリップ９１で容器内方に押圧付勢されている断面視略Ｚ字形状の取付部材９２が設けられている。そして、補強リング８と第２の耐熱樹脂キャップ４は、スペーサ６に対し、取付部材９２を介してバネクリップ９１で真空断熱容器部２の底側に向かって押圧付勢され、この押圧付勢により、真空断熱容器部２やスペーサ６に対して一体化されて取り付けられる。 In this example, a reinforcing ring 8 is provided along the outer surface of the second heat-resistant resin cap, and spring clips 91 and mounting members 92, which are generally Z-shaped in cross section and are pressed toward the inside of the container by the spring clips 91, are provided at multiple locations around the outer wall 22 of the vacuum insulated container portion 2. The reinforcing ring 8 and second heat-resistant resin cap 4 are pressed toward the bottom of the vacuum insulated container portion 2 by the spring clips 91 via the mounting members 92 against the spacer 6, and are attached as a single unit to the vacuum insulated container portion 2 and spacer 6 due to this pressing force.
潜熱蓄熱材５は、第１の耐熱樹脂キャップ３と第２の耐熱樹脂キャップ４とスペーサ６で囲まれる封入空間Ｓに封入される。潜熱蓄熱材５には、例えばゲル状のパラフィン系潜熱蓄熱材のようなゲル状有機系潜熱蓄熱材、二酸化バナジウム焼結体等の非流動性潜熱蓄熱材を用い、非流動性潜熱蓄熱材を封入空間Ｓに封入する構成とすると好適であるが、潜熱蓄熱材５の封入空間Ｓの防水性、防液性を確保できる場合には、流動性潜熱蓄熱材を用い、流動性潜熱蓄熱材を封入空間Ｓに封入する構成とすることも可能である。また、潜熱蓄熱材５として、パラフィン系潜熱蓄熱材のような有機系潜熱蓄熱材が封入されたマイクロカプセルを複数個用い、有機系潜熱蓄熱材が封入されたマイクロカプセルの多数個を封入空間Ｓに封入する構成としても好適である。また、潜熱蓄熱材５には、固体－液体相転移による潜熱蓄熱材を用いると好適であるが、例えば電子相転移による潜熱蓄熱材を用いることも可能である。 The latent heat storage material 5 is sealed in the sealed space S surrounded by the first heat-resistant resin cap 3, the second heat-resistant resin cap 4, and the spacer 6. It is preferable to use a gel-like organic latent heat storage material such as a gel-like paraffin-based latent heat storage material or a non-fluid latent heat storage material such as vanadium dioxide sintered compact as the latent heat storage material 5, and to seal the non-fluid latent heat storage material in the sealed space S. However, if the waterproof and liquid-proof properties of the sealed space S for the latent heat storage material 5 can be ensured, it is also possible to use a fluid latent heat storage material and seal the fluid latent heat storage material in the sealed space S. It is also preferable to use multiple microcapsules containing an organic latent heat storage material such as a paraffin-based latent heat storage material as the latent heat storage material 5, and to seal a large number of these microcapsules containing the organic latent heat storage material in the sealed space S. Furthermore, it is preferable to use a latent heat storage material that undergoes a solid-liquid phase transition as the latent heat storage material 5, but it is also possible to use a latent heat storage material that undergoes an electronic phase transition, for example.
また、測定機器収容用断熱容器１の内部と外部の電波による無線通信を確保する観点からは、第１の耐熱樹脂キャップ３と第２の耐熱樹脂キャップ４とを電磁波透過性材料で形成すると共に、潜熱蓄熱材５が相変化の前後で絶縁性を維持する材料で形成することが好ましい。この場合における第１の耐熱樹脂キャップ３と第２の耐熱樹脂キャップ４に用いる材料としては、例えばポリエーテル・エーテル・ケトン（ＰＥＥＫ樹脂）、ポリフェニレンサルファイド（ＰＰＳ樹脂）、ＰＢＴ－ＧＦ３０のようなガラス繊維入りのポリブチレンテレフタレート等とすると、２００℃以上の耐熱性を確保できて好適である。また、潜熱蓄熱材５に用いる材料としては、例えば相変化温度が４０℃のパラフィン系潜熱蓄熱材等を用いると測定機器収容用断熱容器１の内部の温度を５０℃以下に保つことができて好適である。 Furthermore, from the perspective of ensuring wireless radio communication between the inside and outside of the insulated container for housing measuring instruments 1, it is preferable to form the first heat-resistant resin cap 3 and the second heat-resistant resin cap 4 from an electromagnetic wave-transmitting material, and to form the latent heat storage material 5 from a material that maintains its insulating properties before and after a phase change. In this case, materials such as polyether ether ketone (PEEK resin), polyphenylene sulfide (PPS resin), and glass fiber-reinforced polybutylene terephthalate (PBT-GF30) are suitable for the first heat-resistant resin cap 3 and the second heat-resistant resin cap 4, as they can ensure heat resistance of 200°C or higher. Furthermore, materials such as paraffin-based latent heat storage materials with a phase change temperature of 40°C are suitable for the latent heat storage material 5, as they can maintain the temperature inside the insulated container for housing measuring instruments 1 at 50°C or lower.
真空断熱容器部２の内部のインナーケース７に収容される測定機器１０は、測定機器収容用断熱容器１の外部に設けられるセンサーの測定値を取得して処理すると共に、測定機器収容用断熱容器１の内外に接続ケーブルが設けられる適宜の測定機器とすることが可能であり、例えば測定機器収容用断熱容器１の内外にセンサーとの接続ケーブルが設けられ、接続ケーブルを介してセンサーの測定値を取得して処理する測定機器とすると好適である。 The measuring device 10 housed in the inner case 7 inside the vacuum insulated container section 2 acquires and processes measurements from a sensor located outside the insulated container 1 for housing a measuring device, and can be any suitable measuring device with a connection cable installed inside and outside the insulated container 1 for housing a measuring device. For example, it is preferable for the measuring device to have a connection cable to the sensor installed inside and outside the insulated container 1 for housing a measuring device, and acquire and process measurements from the sensor via the connection cable.
図示例の測定機器１０は、ＣＰＵ、メモリ、制御プログラムを格納したＲＯＭ等で構成され、測定機器収容用断熱容器１の外部に設けられるセンサー（図示省略）から接続ケーブル１１を介して取得する測定値の処理を担う処理する制御処理ユニット１２と、ハードディスク等で構成され、センサーの測定値を時系列順等で格納する記憶部１３と、バッテリー１４を備える。制御処理ユニット１２と記憶部１３、制御処理ユニット１２とバッテリー１４は、それぞれ図示省略する接続線で電気的に接続されている。測定機器１０は、保持部材１５１、１５２、１５３で保持されてインナーケース７の内部の所定位置に設置されている。 The measuring device 10 in the illustrated example is comprised of a control processing unit 12, which is composed of a CPU, memory, ROM storing a control program, etc. and is responsible for processing measurement values acquired via a connection cable 11 from a sensor (not shown) located outside the insulated container 1 for housing a measuring device; a memory unit 13, which is composed of a hard disk or the like and stores the sensor measurement values in chronological order, etc.; and a battery 14. The control processing unit 12 and memory unit 13, and the control processing unit 12 and battery 14 are electrically connected by connection lines, not shown. The measuring device 10 is held by holding members 151, 152, 153 and installed in a predetermined position inside the inner case 7.
測定機器１０の制御処理ユニット１２に接続されている接続ケーブル１１は、第１の耐熱樹脂キャップ３と、潜熱蓄熱材５と、第２の耐熱樹脂キャップ４を貫通するように配線されて、測定機器収容用断熱容器１の外部に引き出され、測定機器収容用断熱容器１の外部に設けられるセンサー（図示省略）に接続されている。尚、本例の接続ケーブル１１は、導線に絶縁被覆が施された一般的な接続ケーブルになっている。 The connection cable 11 connected to the control processing unit 12 of the measuring device 10 is wired so as to pass through the first heat-resistant resin cap 3, the latent heat storage material 5, and the second heat-resistant resin cap 4, and is then drawn out to the outside of the insulated container 1 for housing the measuring device and connected to a sensor (not shown) located outside the insulated container 1 for housing the measuring device. Note that the connection cable 11 in this example is a typical connection cable with an insulating coating on the conductor.
第１の耐熱樹脂キャップ３と第２の耐熱樹脂キャップ４に形成されている接続ケーブル１１の貫通穴は、その周面の全体が接続ケーブル１１の外周に接触するように形成されており、測定機器収容用断熱容器１の内外の断熱性が高められている。また、潜熱蓄熱材５に設けられている接続ケーブル１１の貫通穴は、その周面の全体が接続ケーブル１１の外周に接触するように設けられており、接続ケーブル１１の外周に潜熱蓄熱材５を接触させることで、接続ケーブル１１の熱を潜熱蓄熱材５に伝導させ、潜熱蓄熱材５に蓄熱することができるようになっている。 The through holes for the connection cable 11 formed in the first heat-resistant resin cap 3 and the second heat-resistant resin cap 4 are formed so that their entire periphery is in contact with the outer periphery of the connection cable 11, thereby improving the thermal insulation inside and outside the insulated container for housing measuring equipment 1. Furthermore, the through holes for the connection cable 11 formed in the latent heat storage material 5 are formed so that their entire periphery is in contact with the outer periphery of the connection cable 11. By bringing the latent heat storage material 5 into contact with the outer periphery of the connection cable 11, the heat of the connection cable 11 can be conducted to the latent heat storage material 5 and stored in the latent heat storage material 5.
潜熱蓄熱材５としてゲル状パラフィン系潜熱蓄熱材のようなゲル状有機系潜熱蓄熱材を用い、ゲル状有機系潜熱蓄熱材を封入空間Ｓに封入する場合、ゲル状有機系潜熱蓄熱材に接続ケーブル１１を直接貫通させ、ゲル状有機系潜熱蓄熱材が接続ケーブル１１の外周に固体－液体相転移の前後で常時、直接接触するように設けると、ゲル状有機系潜熱蓄熱材と接続ケーブル１１の外周との接触性を固体－液体相転移の前後で確実に確保することができて好適である。特に、相転移温度を超えると流動性が高くなるゲル状パラフィン系潜熱蓄熱材を用いると、高温化したゲル状パラフィン系潜熱蓄熱材と接続ケーブル１１の外周と間の隙間を確実に埋め、接触性、伝熱抑制性をより高めることができる。 When a gel-like organic latent heat storage material such as a paraffin-based latent heat storage material is used as the latent heat storage material 5 and is sealed in the sealed space S, the connection cable 11 can be directly passed through the gel-like organic latent heat storage material so that the gel-like organic latent heat storage material is in constant direct contact with the outer periphery of the connection cable 11 before and after the solid-liquid phase transition, which is advantageous in ensuring reliable contact between the gel-like organic latent heat storage material and the outer periphery of the connection cable 11 before and after the solid-liquid phase transition. In particular, using a paraffin-based latent heat storage material that becomes more fluid above its phase transition temperature reliably fills the gap between the heated gel-like paraffin-based latent heat storage material and the outer periphery of the connection cable 11, further improving contact and heat transfer suppression.
ゲル状パラフィン系潜熱蓄熱材のようなゲル状有機系潜熱蓄熱材を封入空間Ｓに封入する場合、封入空間Ｓのほぼ全体に亘ってゲル状有機系潜熱蓄熱材を充填すると、測定機器収容用断熱容器１の使用方向の規制を無くすことができると共に、封入空間Ｓ内における接続ケーブル１１の長さ全体に亘ってゲル状有機系潜熱蓄熱材を接触させ、伝熱抑制性を高めることができて好適である。また、測定機器収容用断熱容器１の使用方向が第２の耐熱樹脂キャップ４を下側又は上側に規制される場合には、ゲル状パラフィン系潜熱蓄熱材のようなゲル状有機系潜熱蓄熱材が封入空間Ｓの下半分以上の高さを埋めるようにして、ゲル状有機系潜熱蓄熱材を封入空間Ｓに封入すると、封入空間Ｓ内における接続ケーブル１１の長さの半分以上に亘ってゲル状有機系潜熱蓄熱材を接触させ、必要な伝熱抑制性を確保することができると共に、ゲル状有機系潜熱蓄熱材の使用量を減らし製造コストを低減することができて好適である。 When a gel-like organic latent heat storage material such as a gel-like paraffin-based latent heat storage material is enclosed in the enclosed space S, filling almost the entire enclosed space S with the gel-like organic latent heat storage material is advantageous because it eliminates restrictions on the direction of use of the insulated container 1 for housing measuring equipment, and also allows the gel-like organic latent heat storage material to be in contact with the entire length of the connection cable 11 within the enclosed space S, thereby improving heat transfer inhibition. Furthermore, if the direction of use of the insulated container 1 for accommodating measuring instruments is restricted to either the upper or lower side of the second heat-resistant resin cap 4, sealing the gel-like organic latent heat storage material, such as a gel-like paraffin-based latent heat storage material, in the enclosed space S so that it fills at least half the height of the lower half of the enclosed space S allows the gel-like organic latent heat storage material to contact at least half the length of the connection cable 11 within the enclosed space S, ensuring the necessary heat transfer suppression, and reducing the amount of gel-like organic latent heat storage material used and manufacturing costs, which is advantageous.
また、パラフィン系潜熱蓄熱材のような有機系潜熱蓄熱材が封入されたマイクロカプセルの複数個を封入空間Ｓに封入する場合、多数のマイクロカプセルの集合体を貫通するように接続ケーブル１１を設け、マイクロカプセルの集合体が接続ケーブル１１の外周に固体－液体相転移の前後で常時接触するようにすると、潜熱蓄熱材５に相当する有機系潜熱蓄熱材が封入されたマイクロカプセルの集合体と接続ケーブル１１の外周との接触性を固体－液体相転移の前後で確実に確保することができて好適である。 Furthermore, when multiple microcapsules filled with an organic latent heat storage material such as a paraffin-based latent heat storage material are enclosed in the enclosed space S, a connection cable 11 can be provided so as to pass through the assembly of multiple microcapsules, and the assembly of microcapsules can be kept in constant contact with the outer periphery of the connection cable 11 before and after the solid-liquid phase transition. This is advantageous as it ensures reliable contact between the assembly of microcapsules filled with an organic latent heat storage material equivalent to the latent heat storage material 5 and the outer periphery of the connection cable 11 before and after the solid-liquid phase transition.
パラフィン系潜熱蓄熱材のような有機系潜熱蓄熱材が封入されたマイクロカプセルの多数個或いは集合体を封入空間Ｓに封入する場合、封入空間Ｓのほぼ全体に亘って有機系潜熱蓄熱材が封入されたマイクロカプセルを充填すると、測定機器収容用断熱容器１の使用方向の規制を無くすことができると共に、封入空間Ｓ内における接続ケーブル１１の長さ全体に亘って有機系潜熱蓄熱材が封入されたマイクロカプセルの集合体を接触させ、伝熱抑制性を高めることができて好適である。また、測定機器収容用断熱容器１の使用方向が第２の耐熱樹脂キャップ４を下側又は上側に規制される場合には、有機系潜熱蓄熱材が封入されたマイクロカプセルの集合体が封入空間Ｓの下半分以上の高さを埋めるようにして封入空間Ｓに封入すると、封入空間Ｓ内における接続ケーブル１１の長さの半分以上に亘って有機系潜熱蓄熱材が封入されたマイクロカプセルを接触させ、必要な伝熱抑制性を確保することができると共に、有機系潜熱蓄熱材が封入されたマイクロカプセルの使用量を減らし製造コストを低減することができて好適である。 When a large number or clusters of microcapsules containing an organic latent heat storage material such as a paraffin-based latent heat storage material are enclosed in the enclosed space S, filling almost the entire enclosed space S with microcapsules containing the organic latent heat storage material eliminates restrictions on the direction of use of the insulated container 1 for accommodating measuring equipment, and allows the clusters of microcapsules containing the organic latent heat storage material to come into contact along the entire length of the connection cable 11 within the enclosed space S, thereby improving heat transfer suppression, which is advantageous. Furthermore, when the direction of use of the insulated container 1 for accommodating measuring equipment is restricted to the upward or downward direction of the second heat-resistant resin cap 4, if a collection of microcapsules containing an organic latent heat storage material is enclosed in the enclosed space S so that it fills at least half the height of the lower half of the enclosed space S, the microcapsules containing the organic latent heat storage material will be in contact over at least half the length of the connection cable 11 within the enclosed space S, ensuring the necessary heat transfer suppression, and reducing the amount of microcapsules containing organic latent heat storage material used and reducing manufacturing costs, this is advantageous.
本実施形態の測定機器収容用断熱容器１は、例えば接続ケーブル１１の先端に変位センサーが設けられ、変位の測定値を取り込んで格納する変位測定機器の測定機器１０を内装するようにして使用される。そして、例えば変位測定機器の測定機器１０が内装された測定機器収容用断熱容器１が自動車の車体に取付部材９２を介して取り付けられると共に変位センサーが車体の所要位置に設置され、車体製造工程における車体の塗装槽への浸漬、車体の乾燥炉での加熱乾燥の工程を通じて、測定機器収容用断熱容器１の車体への取付状態が維持され、塗装槽の水圧による変形や加熱乾燥の熱による変形で生ずる車体の変形変位が測定機器１０の記憶部１３に格納される。 In this embodiment, the insulated container 1 for housing a measuring device is used by, for example, providing a displacement sensor at the tip of the connection cable 11 and housing a measuring device 10 for displacement measurement that captures and stores displacement measurements. Then, for example, the insulated container 1 for housing a measuring device housing a measuring device housing the measuring device 10 is attached to the body of an automobile via a mounting member 92, and the displacement sensor is installed at a required position on the body. The attached state of the insulated container 1 for housing a measuring device to the body is maintained throughout the processes of immersing the body in a paint tank and drying the body in a drying oven during the body manufacturing process, and deformation of the body caused by water pressure in the paint tank and heat during drying is stored in the memory unit 13 of the measuring device 10.
本実施形態の測定機器収容用断熱容器１によれば、潜熱蓄熱材５を貫通するように配線される測定機器１０の接続ケーブル１１の外周に潜熱蓄熱材５を接触させることにより、接続ケーブル１１を介した容器内外の伝熱を抑制し、収容される測定機器１０の断熱保護を確実に図ることができる。また、外部と熱の流入・流出量が高くなる測定機器収容用断熱容器１の開口側に、第１の耐熱樹脂キャップ３と第２の耐熱樹脂キャップ４とその間の潜熱蓄熱材５による三重構造を設けることにより、測定機器収容用断熱容器１の断熱性をより高めることができる。 In the insulated container 1 for housing measuring equipment of this embodiment, by contacting the latent heat storage material 5 with the outer periphery of the connection cable 11 of the measuring equipment 10, which is wired so as to pass through the latent heat storage material 5, heat transfer between the inside and outside of the container via the connection cable 11 is suppressed, ensuring reliable thermal protection of the housed measuring equipment 10. Furthermore, by providing a triple structure consisting of the first heat-resistant resin cap 3, the second heat-resistant resin cap 4, and the latent heat storage material 5 between them on the opening side of the insulated container 1 for housing measuring equipment, where the amount of heat flowing in and out of the outside is high, the thermal insulation of the insulated container 1 for housing measuring equipment can be further improved.
また、測定機器１０が収容される有底筒状のインナーケース７の開口側の端部をスペーサ６の外周側のシール材６２で真空断熱容器部２の内周壁２４に向かって押圧付勢してインナーケース７を固定することにより、真空断熱容器部２の内部にインナーケース７を簡単に着脱自在に固定することができる。従って、インナーケース７やこれに収容される測定機器１０のメンテナンスや取替を容易に行うことができる。また、インナーケース７の開口側の端部をシール材６２で押圧付勢することにより、測定機器１０が収容されるインナーケース７の内部への水の浸入をより確実に防止することができる。 Furthermore, by pressing and urging the open end of the bottomed cylindrical inner case 7, which houses the measuring instrument 10, toward the inner wall 24 of the vacuum insulated container section 2 with the sealing material 62 on the outer periphery of the spacer 6, the inner case 7 can be easily and detachably fixed inside the vacuum insulated container section 2. This makes it easy to maintain and replace the inner case 7 and the measuring instrument 10 housed therein. Furthermore, by pressing and urging the open end of the inner case 7 with the sealing material 62, it is possible to more reliably prevent water from entering the interior of the inner case 7, which houses the measuring instrument 10.
また、第２の耐熱樹脂キャップ４をバネクリップ９１でスペーサ６に押圧付勢することにより、第２の耐熱樹脂キャップ４とスペーサ６との当接領域の密着性を高め、測定機器収容用断熱容器１の断熱性をより高めることができる。また、補強リング８を介して第２の耐熱樹脂キャップ４をバネクリップ９１でスペーサ６に押圧付勢することにより、第２の耐熱樹脂キャップ４の変形を防止することができる。 In addition, by pressing the second heat-resistant resin cap 4 against the spacer 6 with the spring clip 91, the adhesion at the contact area between the second heat-resistant resin cap 4 and the spacer 6 is improved, further improving the thermal insulation of the insulated container for accommodating measuring instruments 1. In addition, by pressing the second heat-resistant resin cap 4 against the spacer 6 with the spring clip 91 via the reinforcing ring 8, deformation of the second heat-resistant resin cap 4 can be prevented.
また、第１の耐熱樹脂キャップ３と第２の耐熱樹脂キャップ４とを電磁波透過性材料で形成すると共に、潜熱蓄熱材５を相変化の前後で絶縁性を維持する材料で形成する場合には、第１の耐熱樹脂キャップ３と第２の耐熱樹脂キャップ４とその間の潜熱蓄熱材５が設けられる測定機器収容用断熱容器１の開口側で電波を常時透過させることができ、測定機器収容用断熱容器１の内部に収容される測定機器１０を外部から無線通信で制御することが可能となる。 Furthermore, if the first heat-resistant resin cap 3 and the second heat-resistant resin cap 4 are formed from an electromagnetic wave-transmitting material and the latent heat storage material 5 is formed from a material that maintains its insulating properties before and after a phase change, radio waves can be constantly transmitted through the opening side of the insulated container 1 for accommodating measuring equipment, where the first heat-resistant resin cap 3, the second heat-resistant resin cap 4, and the latent heat storage material 5 between them are located, making it possible to externally control the measuring equipment 10 housed inside the insulated container 1 for accommodating measuring equipment via wireless communication.

The inventions disclosed in this specification also include the following modifications and additions.
例えば本発明の測定機器収容用断熱容器に収容される測定機器は本発明の趣旨の範囲内で適宜であり、変位測定機器以外の各種の測定機器とすることが可能である。更に、測定機器の接続ケーブルの先端にセンサーを設ける場合のセンサーも、測定機器収容用断熱容器に収容される測定機器の種類に応じて適宜である。 For example, the measuring instrument housed in the insulated container for housing measuring instruments of the present invention may be any suitable measuring instrument within the spirit and scope of the present invention, and may be any type of measuring instrument other than a displacement measuring instrument. Furthermore, when a sensor is attached to the tip of the connecting cable of the measuring instrument, the sensor may also be suitable depending on the type of measuring instrument housed in the insulated container for housing measuring instruments.
また、本発明の測定機器収容用断熱容器に収容される測定機器と、測定機器収容用断熱容器の外部のセンサーとが、測定機器収容用断熱容器の第２の耐熱樹脂キャップ側から無線通信を行って、測定機器がセンサーの測定値を取り込み、測定機器の接続ケーブルが各々の測定機器の測定値を管理する管理サーバのような管理装置等に接続される構成も本発明に含まれる。 The present invention also includes a configuration in which a measuring device housed in the insulated container for housing a measuring device of the present invention and a sensor outside the insulated container for housing a measuring device communicate wirelessly from the second heat-resistant resin cap side of the insulated container for housing a measuring device, the measuring device captures the sensor's measurement values, and the connecting cable of the measuring device is connected to a management device such as a management server that manages the measurement values of each measuring device.
また、上記実施形態のように、測定機器収容用断熱容器１の最外側が真空断熱容器部２の外側底板２１と外周壁２２と第２の耐熱樹脂キャップ４となるようにすると、測定機器収容用断熱容器の軽量化を図ることができて好適であるが、例えば真空断熱容器部２の外側底板２１と外周壁２２の外側を有底筒状の耐圧容器で囲む構成等とすることも可能である。また、本発明の測定機器収容用断熱容器は、測定機器の外部環境が高温になる場合の他、測定機器の外部環境が低温になる場合に用いても好適である。 Furthermore, as in the above embodiment, the outermost parts of the insulated container 1 for housing measuring equipment are the outer bottom plate 21, outer peripheral wall 22, and second heat-resistant resin cap 4 of the vacuum insulated container portion 2, which is preferable because it allows for a lighter insulated container for housing measuring equipment. However, it is also possible to configure the outside of the outer bottom plate 21 and outer peripheral wall 22 of the vacuum insulated container portion 2 to be surrounded by a bottomed, cylindrical pressure-resistant container, for example. Furthermore, the insulated container for housing measuring equipment of the present invention is suitable for use not only when the external environment of the measuring equipment is high, but also when the external environment of the measuring equipment is low.
本発明は、例えば加熱乾燥炉内など測定機器の外部環境が高温になる際に利用することができる。 The present invention can be used when the external environment of the measuring instrument becomes hot, for example, inside a heating and drying oven.
