【発明の詳細な説明】
本発明は熱交換器の製造法に関し、この熱交換器部材が
銅または銅合金よりつくられていることに着目し、その
通電特性を利用して上記部材のろう付けを合理的に行っ
たものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a heat exchanger, and focuses on the fact that the heat exchanger member is made of copper or copper alloy, and utilizes the electrical conductivity properties of the heat exchanger member to braze the above member. This is a rational approach.
従来のこの種熱交換器にあっては、熱交換器部材が銅な
どの電気良導材でつくられていたため、スポット溶接が
むづかしく、ほとんどがろう付けに頼っていた。In conventional heat exchangers of this type, the heat exchanger components were made of electrically conductive materials such as copper, which made spot welding difficult and most relied on brazing.
ろう付け手段としてはバーナで加熱する方式，高温不活
性ガス中に通して行う方式があるが、しかし、前者の方
式では、バーナで加熱される部分の熱歪みが著しく、ま
たフラックスを使用していたため、ろう付け後酸洗いな
どを行う必要があり、工程が複雑となる欠点があった。There are two methods of brazing: heating with a burner and passing it through high-temperature inert gas. However, with the former method, there is significant thermal distortion of the part heated by the burner, and flux is not used. Therefore, it is necessary to perform pickling after brazing, which has the disadvantage of complicating the process.
また後者方式でも炉中での材料軟化によって、ろう付け
後の変形が著しい欠点があった。本発明はこのような従
来の欠点を解消したもので、以下その実施例を添付図面
とともに説明する。The latter method also had the disadvantage of significant deformation after brazing due to material softening in the furnace. The present invention eliminates these conventional drawbacks, and embodiments thereof will be described below with reference to the accompanying drawings.
図において、熱交換器１は、熱伝導性のよい銅または銅
合金材の平板２と波形板３とから横成されている。In the figure, a heat exchanger 1 is made up of a flat plate 2 and a corrugated plate 3 made of copper or a copper alloy material with good thermal conductivity.
さらに述べると、波形板３の波底部３ａが平板２にろう
付けされ、上記平板２と波形板３とで区割された空間を
熱媒体通路４として設定してある。More specifically, the corrugated bottom portion 3a of the corrugated plate 3 is brazed to the flat plate 2, and the space divided between the flat plate 2 and the corrugated plate 3 is set as a heat medium passage 4.
第２図は上記ろう付け手段を示すもので、まず、間に平

当てる。FIG. 2 shows the above-mentioned brazing means. First, the corrugated bottom portion 3a of the corrugated plate 3 is applied to the lower surface of the flat plate 2 with a flat plate-shaped brazing material 5 placed in between, and then the corrugated bottom part 3a of the corrugated plate 3 The protruding portions 6a of the rack-shaped electrodes 6 are formed with the same pitch as the pitch.
are arranged between the corrugations, and the protrusion 7a of the pinion-shaped electrode 7 having the same pitch as the waveform pitch is applied to the upper surface of the flat plate 2.

である。Here, using the conductivity of the flat plate 2 and the corrugated plate 3, both electrodes 6
, 7, and rotate one electrode 6 laterally and the other electrode 7 in the direction of movement of the electrode 6.
The brazing filler metal 5 facing between the flat plate 2 and the corrugated bottom portion 3a of the corrugated plate 3 is melted, and brazing is performed at the same portion. As described above, according to the present invention, since the conductivity of the heat exchanger member is used to melt and braze the wax, it is much easier to use in terms of process and equipment than the conventional method. It can be simplified and has excellent effects such as no thermal distortion or deformation due to heating and softening of the heat exchanger member.
