Description

Technical Field

[0001] The utility model belongs to the technical field of waste heat recovery devices, and more specifically, relates to a waste heat recovery heat management device for electric vehicles. Background Art

[0002] During the operation of electric vehicles, batteries, motors and other components will generate a large amount of waste heat. If this waste heat can be effectively recycled and utilized, it can reduce dependence on external energy and improve the energy utilization efficiency of electric vehicles. The motor will generate a large amount of heat when working. This heat can be taken away by the R290 coolant in the cooling system. The waste heat recovery device will collect the heat through the heat exchanger during the circulation of the R290 coolant.

[0003] The existing application number is CN202120799938.X. This utility model provides an electric vehicle thermal management system, comprising a refrigerant circuit, a powertrain cooling circuit, and a battery cooling circuit. The refrigerant circuit includes a compressor, a three-way valve, an internal heat exchanger, a first expansion device, a first heat exchanger, an external heat exchanger, a second expansion device, an evaporator, a third expansion device, a second heat exchanger, a shut-off valve, a gas-liquid separator, and a third heat exchanger. The compressor is connected to the first port of the three-way valve, the second port of the three-way valve is connected to the internal heat exchanger, and the third port of the three-way valve is connected to the third heat exchanger. The battery cooling circuit is connected to the second and third heat exchangers, and the powertrain cooling circuit is connected to the first heat exchanger. This system optimizes battery heating and waste heat recovery, improving system operating efficiency and thereby increasing the range of electric vehicles.

[0004] Based on the above, existing electric vehicles generally use plate heat exchangers to recover and manage vehicle waste heat. During the use of the plate heat exchanger, since the outside cold air needs to be exchanged into hot air for utilization, after the outside air enters the heat exchanger, due to the large amount of impurities contained in the outside air, long-term use can easily cause the exhaust pipe to be blocked. Once the exhaust pipe is blocked, if the user fails to discover it in time, it is easy to damage the entire heat exchanger. Utility Model Content
