密閉筐体12の外気側にある放熱部5にて放熱される。A heat pipe type sealed case cooler is a heat pipe type sealed case cooler in which electronic and electrical equipment such as control panels and operation panels that are sensitive to dust are placed inside a sealed case, and the heat generated by the electronic and electrical equipment is transferred to the outside via a heat pipe while maintaining the airtight state. The structure is as shown in Figure 3 as an example of a ceiling-mounted heat pipe.
The heat receiving part 4 is placed on the inside air side of the sealed casing 12, and the heat radiating part 5 is placed on the outside air side above the ceiling. The heat is received by the heat receiving part 4 of the heat pipe 1, and this heat is radiated by the heat radiating part 5 located on the outside air side of the sealed casing 12 through the inside of the heat pipe 1.

As shown in FIG. 2, the attachment is performed through the partition plate 3. That is, a hole with a diameter slightly smaller than the outer diameter of the heat pipe 1 is drilled in the partition plate 3 by burring, and the heat pipe 1 is press-fitted into this hole and attached.
This is done by tightening bolts to the sealed casing via gaskets (not shown).

。Next, an example of the procedure for attaching the heat pipe to the partition plate is shown in the first section.
This will be explained with reference to the figures. First, holes are made in the fin 2 by burring, a predetermined number of fins 2 are arranged with the holes aligned, and the heat receiving part 4 of the heat pipe 1 is press-fitted into the hole to fix the fin 2 to the heat pipe 1. Next, a hole with a diameter slightly larger than the outer diameter of the heat pipe 1 is punched out in the partition plate 3, and the heat receiving part 4 of the heat pipe 1 is inserted into this hole.
the partition plate 3 is tightly applied to the adjacent lower fin 2 and pressed to fix it, and further, adhesive 6 is densely filled between the heat pipe 1 and the partition plate 3 to fix it, Thereafter, a predetermined number of fins 2 are press-fitted into the heat dissipation section 5 of the heat pipe 1 in the same manner as described above, and the fins 2 are assembled.

ト的に廉価である。(Function) In the cooler of the present invention, the heat pipe is attached to the partition plate by densely filling or applying adhesive in the gap between the partition plate and the heat pipe or/and the fins. The heat pipe can be firmly and airtightly attached to the partition plate.Furthermore, since the attachment is done with adhesive, there is no need to use a thick plate for the partition plate, making assembly work easy and inexpensive.
以下に本発明を実施例により詳細に説明する。 The present invention will be explained in detail below using examples.

、シリコンシーラント(東芝シリコン社製)を用いた。In the above cooler, the heat pipe 1 was a heat pipe unit in which 16 12φ heat pipes 1 were integrated through fins, and the partition plate 3 was a Zn-plated steel plate with a thickness of 2 mm. Further, the clearance between the heat pipe 1 and the partition plate 3 was set to 0.51, and the adhesive 6 was silicone sealant (manufactured by Toshiba Silicon Co., Ltd.).

る為、厚さ2.7mmのZnメツキ鋼板を用いた。For comparison, the dustproof performance of the conventional cooler shown in FIG. 2 was also tested in the same manner as above. In this cooler, a Zn-plated steel plate with a thickness of 2.7 mm was used for the partition plate 3 in order to increase the adhesion strength with the heat pipe.
上記の2種の冷却器を1年間連続して使用したのち、冷

クリープ現象等がおきた為と考えられる。On the other hand, in the conventional cooler, dust was allowed to enter the inside, and there were minute gaps between the partition plate 3 and the heat pipe 1. This is because the attachment of the heat pipe 1 to the partition plate 3 is simply mechanically sealed by press-fitting.
This is thought to be due to a creep phenomenon, etc.
