Vehicular absorption cooling system utilizing engine waste heat

Abstract

The invention discloses a absorb cooling system which use the waste heat of engine for automobile, the invention includes a generator which uses the waste heat of auto engine, a condenser which can cool the high-handed gaseous secondary refrigerant from the generator to fluent secondary refrigerant, a step down unit which can step down the fluent secondary refrigerant, a evaporator which is fixed in the vehicle room and can help the secondary refrigerant absorb heat and be vaporized, and absorber which can cool the gaseous secondary and make it be absorbed by the generator and mix with the absorbefacient to liquor. So use the engine waste heat as the necessary heat energy of the system, the energy saving and recycle can be achieved.

Description

technical field [0001] The invention relates to a cooling system for a vehicle, in particular to an absorption cooling system for a vehicle using the exhaust heat of the engine, which can complete the cycle by using the waste heat discharged from the vehicle engine as a heat source. Background technique [0002] Figure 1, figure 2 As shown, it is the U.S. No. 6092381 invention patent case, which is a refrigerator used on a car. It mainly uses the existing refrigerant circulating system 1 (refrigerant circulating system) on the car to keep a refrigerator 2 at a low temperature. The refrigerator 2 has a Box body 201, a cooling box 3 installed at the bottom of the box body 201, a pair of connecting pipes 4 connected to the cooling box 3 and capable of passing out of the box body 201, and an upper cover on the box body 201 5. The inside of the box 201 can place items to be stored at low temperature, such as canned beverages 202. The cooling box 3 has a liquid cooling medium 30...

AI Technical Summary

Problems solved by technology

[0004] 1. The original design of the refrigerant circulation system 1 is only to provide the air-conditioning demand in the car. After connecting the refrigerator in series, the cooling load of the refrigerant circulation system 1 will be increased, which may cause the air-conditioning to not cool or drive more fuel-efficient.

[0005] 2. The operation of the refrigerator 2 must rely on the refrigerant circulation system 1. If the air conditioner is not activated, the refrigerator 2 cannot operate

[0006] 3. The piping project of the connecting pipe 4 must change the refrigerant circulation system 1 of the original car factory

[0008] The high temperature generated by the running of the automobile engine, even after being cooled by cooling water, still retains a relatively high amount of heat, which is directly discharged to the atmosphere through the exhaust pipe, which not only fails to properly use the waste heat, but also causes the global environment to heat up
