ード線である。 As shown in Figs. 1 and 2, the temperature sensing part of a conventional thermostat consists of a square columnar pipe 1 made of metal such as copper fixed to a heat exchange medium flow pipe 4 of a heat exchanger by brazing 5 or the like. A thermostat temperature-sensing section 6 was inserted and fixed in the prismatic pipe using a spring member 9 so as to be in thermal contact with the flow pipe. In the figure, 7

必要があつた。 When fixing a prismatic pipe to a flow pipe by brazing, etc. When brazing, the prismatic pipe is heated by the burner heating to melt the brazing material, causing thermal deformation and changing its shape from before it was fixed by brazing. When inserting the tatsu temperature sensing part and the spring material into the prismatic pipe, it becomes impossible to insert them, leading to quality problems during product assembly. Therefore, when brazing, it was necessary to pay close attention to avoid thermal deformation.

ている。 Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1, 2, and 3. 1 is a prismatic pipe, and its shape before brazing is rectangular with openings 2 and 3 at the ends, and the short sides of the openings 2 and 3 are connected to the heat exchange medium flow pipe 4 of the heat exchanger with brazing material. 5, they are in thermal contact, that is, they are thermally fixed. As shown in FIGS. 3a, b, and c, even if the prismatic pipe 1 is thermally deformed due to heating during brazing, if it is cooled after brazing, it will return to the same shape as before brazing, so-called. Ti that remembers the processed shape before brazing

ある。 The present invention has the thermostat temperature sensing part 6 as described above.
Since the material of the prismatic pipe 1 for fixing to the heat exchange medium distribution pipe 4 is a memory alloy material that remembers the shape before brazing, the prismatic pipe 1 will not be thermally deformed by heating during brazing. Even if this occurs, after cooling it returns to its rectangular shape before brazing, so brazing work can be done without worrying about thermal deformation caused by brazing.
This has great practical effects, such as improving work efficiency, eliminating the possibility that the thermostat temperature sensing part 6 cannot be inserted due to thermal deformation, and improving the quality of product assembly. There is.
