検出して膨張弁を制御するようになつている。Conventional structure and its problems Conventionally, the temperature sensor for controlling the expansion valve attached to the wall of the suction pipe of the compressor is as shown in Figures 1 and 2.
As shown in the figure, a cladding tube 3 made of a copper tube with a temperature sensor 2 fitted and inserted into the suction tube 1 is fixed with a brazed part 4, and a lead wire 5 is connected to an electronic control device etc.
The refrigerant temperature in the suction pipe is detected by the temperature sensor 2 to control the expansion valve.

れない欠点を有していた。 However, in such a conventional mounting structure for the temperature sensor 2, the temperature sensing accuracy varies greatly depending on the degree of soldering (adhesion amount) of the solder 4. In addition, suction pipe 1
The area for heat transfer to the cladding tube 3 side is also smaller, and furthermore, a foreign substance, which is a silver brazing material of the brazing tube 4, is interposed between the suction tube 1 made of a copper tube and the cladding tube 3 also made of a copper tube. Because of this heat transfer, the temperature sensing speed of the refrigerant is slow and the expansion valve cannot be properly controlled.

One end of one cylindrical tube 9b of this temperature sensor tube 9 is an opening 10, the other end is closed by crushing and brazing 11, and the other cylindrical tube 9a is an outlet tube 7, 8.
A refrigerant communication port 9c is provided inside the pipes 7 and 8, which is broken in correspondence with the cylindrical pipe 9b, so that the refrigerant communicates with the cladding pipe 13 directly. Cylindrical tube 9 of the temperature sensor tube 9
b is a temperature sensor 12 covered with a cladding tube 13;
is inserted, and its lead wire 14 is connected to an electronic control device (not shown).

Heat is transferred to the temperature sensor 12 through the cladding tube 13, a temperature signal is input to the electronic control device through the lead wire 14, and an expansion valve signal is output to control the electric expansion valve. The refrigerant then returns to the compressor side through the outlet pipe 8.
