水を循環させ水−空気熱交換器によシ冷却される。Traditional tar? Some cars with a charger are equipped with an intercooler, and the purpose of this is to cool the supercharged air to the engine, which is compressed by the turbocharger and reaches a high temperature. This results in effects such as increased vehicle output, reduced fuel consumption, and improved smoke emissions. There are two ways to cool the supercharged air: air-cooled and water-cooled.
The closed side of the air heat exchanger passes outside air compressed by a turbocharger, and the open side is brought into contact with outside air, and is cooled by the wind from the car, an engine-driven fan, or a fan driven by part of the supercharged air. . On the other hand, the water-cooled type circulates radiator water and is cooled by a water-air heat exchanger.

21 is an air-air heat exchanger that cools the supercharged air compressed by the proar 22 with outside air, and 25 is an air supply pipe to the engine. Note that the prower 22 is rotationally driven by a turbine 23 via a shaft 24. On the other hand, the part surrounded by a broken line 30 is a cooler system for the passenger compartment, and 31 is a compressor, 32 is a condenser, and 3
3 is an expansion valve, and 34 is an evaporator.

ている。However, with the above-mentioned conventional devices, the capacity of the heat exchanger is limited and it is not possible to increase the cooling capacity, and the heat exchanger is less effective when the car is stopped or at very low speed, and the cooling capacity is greatly influenced by the outside air. It has disadvantages such as:
本発明の目的は、前記従来例の欠点を解消し、車の停止

ンタークーラを提供するにある。SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the conventional examples and provide an intercooler with a large cooling capacity that functions even when the vehicle is stopped or when the outside temperature is high.
本発明のインタークーラは、従来のごとく冷却するため
の冷却源を直接外気としたシ冷却水を使用することなく
、圧縮機を使用したクーラーシステムを採用している。The intercooler of the present invention employs a cooler system that uses a compressor instead of using cooling water that directly uses outside air as a cooling source as in the past.

性能を向上させることができる。Therefore, the cooling capacity of the conventional intercooler using running wind and fan wind can be increased, and the cooling capacity is large even when the vehicle is stopped, which makes it possible to increase the engine output when the vehicle starts running. In addition, during adaptive control of the engine system, the supercharging air temperature can be used as a control factor to improve intake efficiency and improve engine performance.

可能となる。The Naori-Ra system does not require an existing system or a newly installed system exclusively for supercharging air. When an existing system is used for the intercooler, the annual effective utilization rate of the system can be increased.

。In this embodiment, unlike the conventional example, the conventional cooler system 3
Pulp 35° is provided with a three-pronged path before and after the evaporator 34 of 0, respectively, and switches the inflow or cutoff of the refrigerant to the refrigerant type intercooler 21 side or the inflow or cutoff of the refrigerant to the evaporator for the vehicle interior cooler. 36, 37, and 38 are installed.

つけて使用する場合にはパルプ３５ 、３６ 。When the refrigerant intercooler 21 is operated, the refrigerant gas is branched from the expansion valve 33 of the cooler system 30 to the evaporator 34, and passes through the pallet f36 to the refrigerant intercooler 21.
The supercharged air is evaporated in the intercooler, and the supercharged air is cooled by the evaporation. □The refrigerant gas that has been vaporized by removing heat is sent to the compressor 31 through the pulp 38. When only the supercharged air is cooled without operating the vehicle interior cooler, the pulp 35° 37 is closed and the pallets f 36 and 38 are opened. Furthermore, when supercharging air cooling and vehicle interior cooling are used simultaneously or with priority, pulp 35, 36 is used.
３７．３８の開度を適宜制御して運転を行う。Operation is performed by appropriately controlling the opening degrees of 37 and 38.

ステムをインタークーラに適用した場合には、クーラー
システムの年間有効利用率を向上させることができる。As mentioned above, the intercooler of the present invention uses a method in which the refrigerant of the refrigeration cycle is evaporated in the evaporator as the cold heat source for the intercooler that cools supercharged air, so the temperature is lower than that of conventional air-cooled or water-cooled intercoolers. The difference can be increased, and more air can be supercharged into the cylinder, increasing output and torque and improving engine performance. Furthermore, when a cooler system for indoor cooling is applied to an intercooler, the annual effective utilization rate of the cooler system can be improved.
