Description

本発明は、エンジン駆動作業機などのエンジンのラジエータ,オイルクーラ,インタークーラ等の熱交換装置に関するものである。   The present invention relates to a heat exchange device such as an engine radiator such as an engine-driven work machine, an oil cooler, or an intercooler.

エンジン駆動作業機としては、エンジンで駆動される発電機,溶接機,圧縮機等があるが、その内、例えば圧縮機においては、エンジン冷却水を冷却するためのラジエータ、圧縮機の潤滑油を冷却するためのオイルクーラ、さらに、エンジン出力向上と排ガス浄化のため吸気を冷却するインタークーラ等の熱交換器を備えている。それらの熱交換器は、例えば、特許文献1に示されるように、エンジンで駆動されるファンにより外部から空気を吸い込み、それを各熱交換器に通して効率よく熱交換させるようにしている。    Engine-driven work machines include generators, welders, compressors, etc. driven by the engine. Among them, for example, in a compressor, a radiator for cooling engine cooling water and lubricating oil for the compressor are used. An oil cooler for cooling and a heat exchanger such as an intercooler for cooling the intake air for engine output improvement and exhaust gas purification are provided. In these heat exchangers, for example, as shown in Patent Document 1, air is sucked from the outside by a fan driven by an engine, and the air is passed through each heat exchanger to efficiently exchange heat.

図9は、第1従来例を示す図で、図9(イ)は、エンジン側から熱交換装置を見た図であり、図9(ロ)は、その側面図である。図9において、1はラジエータ、2,3はオイルクーラ、30はシュラウド、31はファン、32はエンジンである。   FIG. 9 is a view showing a first conventional example, FIG. 9 (a) is a view of the heat exchange device viewed from the engine side, and FIG. 9 (b) is a side view thereof. In FIG. 9, 1 is a radiator, 2 and 3 are oil coolers, 30 is a shroud, 31 is a fan, and 32 is an engine.

この熱交換装置では、オイルクーラを二つに分割してオイルクーラ2,3とし、それらをラジエータ1の左右に並列配置して、ファン31により点線矢印で示すように送られる空気流が、ラジエータ1とオイルクーラ2,3に対してバランスよく通るようにしている。   In this heat exchange device, the oil cooler is divided into two to form oil coolers 2 and 3, which are arranged in parallel on the left and right sides of the radiator 1, and the air flow sent by the fan 31 as indicated by the dotted arrows is the radiator. 1 and the oil coolers 2 and 3 pass in a well-balanced manner.

図10は、第2従来例を示す図である。図10において、符号3〜32は、図9のものに対応しており、33はインタークーラである。なお、ラジエータ1とオイルクーラ2,3の配置は、図9のものと同様である。この熱交換装置では、ラジエータ1とオイルクーラ2,3に対して、空気流の上流側にインタークーラ33を直列配置して、それらの熱交換器を限られた面積内に収納可能とし、かつ、インタークーラ33とラジエータ1,オイルクーラ2,3とに冷却空気が均一に供給されるようにしている。    FIG. 10 is a diagram showing a second conventional example. In FIG. 10, reference numerals 3 to 32 correspond to those in FIG. 9, and 33 is an intercooler. The arrangement of the radiator 1 and the oil coolers 2 and 3 is the same as that shown in FIG. In this heat exchanging device, an intercooler 33 is arranged in series upstream of the air flow with respect to the radiator 1 and the oil coolers 2 and 3 so that these heat exchangers can be accommodated within a limited area, and The cooling air is supplied uniformly to the intercooler 33 and the radiators 1, the oil coolers 2, and 3.

ところで、エンジン駆動作業機は、建設現場等の屋外で使用されることが多いため、冷却空気には塵埃が混入していることが多い。そのため、ラジエータやオイルクーラのコア部に塵埃が付着しやすくなり、その状態を放置しておくと、エンジンのオーバーヒートや潤滑油の早期劣化の原因となることから、適宜、塵埃を除去する必要がある。ところが、複数の熱交換器を直列配置した熱交換装置では、前後の熱交換器で挟まれた部分は非常に清掃しにくい。   By the way, since engine-driven work machines are often used outdoors such as construction sites, dust is often mixed in the cooling air. For this reason, dust easily adheres to the core of the radiator or oil cooler, and leaving it in this state may cause overheating of the engine or early deterioration of the lubricating oil. is there. However, in a heat exchange device in which a plurality of heat exchangers are arranged in series, the portion sandwiched between the front and rear heat exchangers is very difficult to clean.

そこで、特許文献2に示されるように、複数の熱交換器を直列配置した熱交換装置において、前後の熱交換器の間、図10の場合では、ラジエータ1,オイルクーラ2,3とインタークーラ33との間に大きな空間を設け、その空間内にエアーブロー装置等を容易に挿入できるようにした熱交換装置が提案されている。   Therefore, as shown in Patent Document 2, in a heat exchange device in which a plurality of heat exchangers are arranged in series, between the front and rear heat exchangers, in the case of FIG. 10, the radiator 1, the oil coolers 2, 3 and the intercooler A heat exchange device has been proposed in which a large space is provided between the air blower 33 and an air blower or the like can be easily inserted into the space.

また、特許文献3に示されるように、複数の熱交換器を直列配置した熱交換装置において、上流側の熱交換器を、下流側の熱交換器の前面で平行移動可能な構造にして、下流側の熱交換器の清掃が容易にできるようにした熱交換装置が提案されている。

In addition, as shown in Patent Document 3, in the heat exchange device in which a plurality of heat exchangers are arranged in series, the upstream heat exchanger has a structure that can be translated in front of the downstream heat exchanger, There has been proposed a heat exchanging device that can easily clean a downstream heat exchanger.
JP 2005-61276 A JP 2004-60933 A JP 2006-38412 A

しかしながら、上記従来の熱交換装置の内、特許文献2に示されるような熱交換装置には、前後の熱交換器の間に大きな空間を設けるため、熱交換装置の長さが長くなり機械全体が大きくなってしまうという問題点があった。また、特許文献3に示されるような熱交換装置には、上流側の熱交換器の前側に、上流側の熱交換器を平行移動させるための作業スペースが必要になるという問題点があった。    However, among the conventional heat exchange devices described above, the heat exchange device as disclosed in Patent Document 2 has a large space between the front and rear heat exchangers, which increases the length of the heat exchange device. There was a problem that would become large. Moreover, the heat exchange apparatus as shown in Patent Document 3 has a problem that a work space for translating the upstream heat exchanger is required on the front side of the upstream heat exchanger. .

さらに、下流側の熱交換器には、上流側の熱交換器を冷却した後の、温度の高い空気が流れたり、上流側の熱交換器の一部やその支持部材等により空気流が遮られたりして、上流側の熱交換器は、下流側の熱交換器の熱交換性能に影響を与えるが、上記従来の熱交換装置は、上流側の熱交換器の取付位置や取付角度が固定されているため、各熱交換器間の冷却バランスを調整できず、効果的な冷却バランスを得るためには、既存の各熱交換器の組み合わせを変更したり、新規の熱交換器を製作したりする必要があるという問題点があった。   Furthermore, after the upstream heat exchanger has been cooled, high-temperature air flows through the downstream heat exchanger, or the air flow is blocked by a part of the upstream heat exchanger or its support member. However, the upstream heat exchanger affects the heat exchange performance of the downstream heat exchanger. However, the conventional heat exchange device has the mounting position and the mounting angle of the upstream heat exchanger. Because it is fixed, the cooling balance between each heat exchanger cannot be adjusted, and in order to obtain an effective cooling balance, the combination of existing heat exchangers can be changed or a new heat exchanger can be manufactured. There was a problem that it was necessary to do.

本発明は、そのような問題点に鑑み、各熱交換器間の冷却バランスを簡単に調整できるようにし、さらに、前後の熱交換器の間に大きな空間を設けたり、上流側の熱交換器の前側に作業スペースを設けたりすることなく、各熱交換器の清掃や着脱ができるようにすることを目的とするものである。    In view of such a problem, the present invention makes it possible to easily adjust the cooling balance between the heat exchangers, and further provides a large space between the front and rear heat exchangers, or an upstream heat exchanger. It is an object of the present invention to allow each heat exchanger to be cleaned and detached without providing a work space on the front side.

The other end of the second support member is fixed in a removable state with respect to the bottom plate. It is characterized by that.

本発明の熱交換装置は、次のような効果を奏する。    The heat exchange device of the present invention has the following effects.

すなわち、請求項1にかかる発明においては、第1の熱交換器と1台又は複数台の第2の熱交換器の上流側に、第3の熱交換器を直列配置した熱交換装置において、第3の熱交換器は、底板から柱状に立設された第1の支持部材の先端部に一端を固定し、他端を前記底板に固定して、傾斜状に設けられた、断面がコの字状の第2の支持部材の上面に沿わせた状態で、前記コの字状の溝内に収納する形で固定するようにした。その結果、第3の熱交換器の支持部材によって、第3の熱交換器の取付角度を調整することにより、各熱交換器間の冷却バランスを簡単に調整できる。 That is, in the invention according to claim 1, in the heat exchange device in which the third heat exchanger is arranged in series on the upstream side of the first heat exchanger and one or more second heat exchangers, The third heat exchanger has one end fixed to the tip of the first support member erected in a column shape from the bottom plate, and the other end fixed to the bottom plate, and is provided in an inclined shape with a cross-section in a cross section. It was made to fix in the form accommodated in the said U-shaped groove | channel in the state along the upper surface of the U-shaped 2nd supporting member. As a result, the cooling balance between the heat exchangers can be easily adjusted by adjusting the mounting angle of the third heat exchanger with the support member of the third heat exchanger.

また、請求項2にかかる発明においては、請求項1にかかる熱交換装置において、第2の支持部材の傾斜角度を可変にしたので、第3の熱交換器の取付角度の調節がより簡単になる。   Further, in the invention according to claim 2, in the heat exchange device according to claim 1, since the inclination angle of the second support member is made variable, it is easier to adjust the mounting angle of the third heat exchanger. Become.

また、請求項3にかかる発明においては、請求項1又は2にかかる熱交換装置において、第1の支持部材の下端部と底板、及び、第1の支持部材の先端部と第2の支持部材の一端とを、前記第1及び第2の熱交換器の放熱面と平行な方向に回動自在に固定し、第2の支持部材の他端を前記底板に対して取り外し可能な状態で固定するようにした。その結果、第3の熱交換器を上方と、横方向に引き出しながら下方に移動させることが簡単にでき、前後の熱交換器の間に大きな空間を設けたり、上流側の熱交換器の前側に作業スペースを設けたりすることなく、各熱交換器の清掃や着脱が容易にできる。   Moreover, in the invention concerning Claim 3, in the heat exchange apparatus concerning Claim 1 or 2, the lower end part and bottom plate of a 1st supporting member, and the front-end | tip part and 2nd supporting member of a 1st supporting member The other end of the second support member is fixed in a removable state with respect to the bottom plate. I tried to do it. As a result, the third heat exchanger can be easily moved upward and downward while being pulled out in the lateral direction, and a large space is provided between the front and rear heat exchangers, or the front side of the upstream heat exchanger. Each heat exchanger can be easily cleaned and detached without providing a work space.

上でも述べたように、複数の熱交換器を直列配置した熱交換装置では、下流側の熱交換器には、上流側の熱交換器を冷却した後の、温度の高い空気が流れたり、上流側の熱交換器の一部やその支持部材等により空気流が遮られたりして、上流側の熱交換器は、下流側の熱交換器の熱交換性能に影響を与える。そして、上流側の熱交換器が下流側の熱交換器に影響を与えることにより、各熱交換器の冷却バランスが変化する。   As described above, in the heat exchange device in which a plurality of heat exchangers are arranged in series, after the upstream heat exchanger is cooled, high-temperature air flows through the downstream heat exchanger, The air flow is blocked by a part of the upstream heat exchanger or its support member, and the upstream heat exchanger affects the heat exchange performance of the downstream heat exchanger. The upstream heat exchanger affects the downstream heat exchanger, so that the cooling balance of each heat exchanger changes.

例えば、図2(イ)に示すように、ラジエータ1,オイルクーラ2,3の上流側に、インタークーラ8を水平に配置した場合は、オイルクーラ2,3に対してインタークーラ8が図の斜線部分で重なって、その部分でオイルクーラ2,3の冷却効果に影響を与える。一方、図2(ロ)に示すように、インタークーラ8を斜めに配置した場合は、図中斜線で示す、オイルクーラ2,3に対してインタークーラ8が重なる部分の面積は小さくなる。そして、そのような重なる部分の面積は、インタークーラ8を傾斜させる角度を変えれば調節でき、下流側のオイルクーラ2,3に対して上流側のインタークーラ8を冷却した後の熱い空気と冷却していない空気との割合を変えられ、オイルクーラ2,3の冷却効果に与える影響の度合いを調整できる。本発明は、それを利用して、上流側の熱交換器の取付角度を最適な角度にすることにより、各熱交換器の冷却バランスの最適化を図るものである。   For example, as shown in FIG. 2 (a), when the intercooler 8 is disposed horizontally on the upstream side of the radiator 1, the oil coolers 2 and 3, the intercooler 8 is connected to the oil coolers 2 and 3. Overlapping in the shaded area affects the cooling effect of the oil coolers 2 and 3. On the other hand, as shown in FIG. 2 (b), when the intercooler 8 is disposed obliquely, the area of the portion where the intercooler 8 overlaps the oil coolers 2 and 3 indicated by the oblique lines in the figure is reduced. And the area of such an overlapping portion can be adjusted by changing the angle at which the intercooler 8 is inclined, and the hot air and the cooling after the upstream intercooler 8 is cooled with respect to the downstream oil coolers 2 and 3. The ratio with the air which has not been changed can be changed, and the degree of influence on the cooling effect of the oil coolers 2 and 3 can be adjusted. The present invention makes use of this to optimize the cooling balance of each heat exchanger by making the mounting angle of the upstream heat exchanger an optimum angle.
