ため、電磁クラツチの接続を中断することにより
圧縮機を停止し冷房能力を調節していた。 In automotive cooling systems powered by the main engine, the cooling capacity increases when the engine rotates at high speeds, so an automatic expansion valve operates to adjust the refrigerant flow rate to keep the cooling capacity constant. In particular, thermostatic automatic expansion valves have a limited adjustment range, so the compressor was stopped and the cooling capacity was adjusted by disconnecting the electromagnetic clutch.

感を与える等の欠点を有していた。 For this reason, the compressor frequently stops, causing significant fluctuations in the load on the main engine, which has a negative impact on the durability of the main engine and the smooth running performance of the vehicle. This has disadvantages such as overcooling during operation, which causes discomfort to the driver.

An object of the present invention is to provide an automobile cooling device that can improve driver comfort.

The temperature of the cooler 15 is sensed by the temperature sensing tube 22 and the expansion valve 8 is activated.
By throttling, the temperature of the cooler 9 built into the condensing device decreases, and through heat exchange with the condenser 7, the amount of evaporation of the refrigerant in the cooler 15 is kept constant, and the condenser 4 and the engine 1, the amount of heat dissipated from the condenser 6 and the overcooling of the cooler 15 are reduced. Here, FIG. 2 shows a schematic diagram of piping of a condensing device according to an embodiment of the present invention, and in this way, the piping of the condenser 7 and the piping of the cooler 6 are arranged alternately to perform heat exchange. It is something that exists.
