Low-carbon economy has become the main theme of my country's economic development. Pure electric vehicles refer to vehicles that use on-board power as power, use motors to drive wheels, and meet the requirements of road traffic and safety regulations. Pure electric vehicles can reduce oil consumption and reduce polluting gas emissions. They have become an industry that my country is vigorously developing and are gradually receiving more and more attention.

[0003] At present, with the development of electric vehicles, the demand for heating and cooling in automobiles is increasing, so a dual-fluid heat exchanger heat exchange design is often used to meet the heat and cooling needs. However, the applicant has found that the dual-fluid heat exchanger is generally fixedly installed in the electric vehicle, and when the dual-fluid heat exchanger fails to work, it is difficult to quickly repair or replace it. This can easily lead to the vehicle being unable to dissipate heat, and the risk of overheating of various components will seriously affect the use of the vehicle. At the same time, it may cause the vehicle performance to be limited, damage to the control components, and shorten the service life of the vehicle.
