Embodiment Construction

[0016] The invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 As shown, the vehicle air conditioner battery cooling system proposed by the present invention includes: a compressor 1 , a condenser 2 , a first evaporator 3 , a second evaporator 4 and a heat exchanger 5 . The refrigerant discharged from the condenser is divided into two paths, the first path passes through the first throttling device 6 and the first evaporator 3 for battery cooling, and the second path passes through the second throttling device 7 and the second evaporator 4 for cooling the battery. When the passenger cools down, the refrigerant continues to exchange heat in the heat exchanger 5 after exchanging heat in the first and second evaporators, and mixes at the outlet of the heat exchanger, and then returns to the compressor 1 through the pipeline.

[0018] A gas-liquid separator 8 is installed on the suction side of the c...

Abstract

The invention discloses a vehicle air conditioner battery cooling system which comprises a compressor, a condenser, a first evaporator, a second evaporator and a heat exchanger. A refrigerating agentdrained out of the condenser is divided into two branches, the first branch passes through a first throttling device and the first evaporator and is used for cooling a battery, the second branch passes through a second throttling device and the second evaporator and is used for cooling passengers, the refrigerating agent exchanges heat in the first evaporator and the second evaporator and then continuously exchanges heat in the heat exchanger, and the two branches are mixed on an outlet of the heat exchanger and then return back to the compressor. The vehicle air conditioner battery cooling system is combined with a vehicle air conditioning system, the safety of the battery is improved, the problem of condensation does not exists, and meanwhile the situation that the high pressure of the compressor is too high is effectively prevented.

Description

technical field [0001] The invention relates to a cooling system, in particular to a vehicle air-conditioning battery cooling system. Background technique [0002] Electric vehicles are being used more and more due to their environmental protection. Generally, the operating temperature of battery materials should not be higher than 60°C. In summer, the outdoor temperature can reach 40°C. At the same time, the battery itself generates a lot of heat, which causes the temperature of the battery's working environment to rise. Excessive heat accumulation in the battery will cause the battery to run out of control. If the temperature of the battery rises to 300°C, a strong chemical reaction will occur inside the battery. Release gas, forming internal high pressure and explosion. The commonly used cooling methods for vehicle batteries are divided into two types: air cooling and liquid cooling. Liquid cooling is mostly used in electric family cars due to its high sealing requirem...
