Description

technical field

[0001] The present invention relates to the fields of electric vehicle technology and thermoelectric technology, in particular to an electric vehicle heat sink with simple structure, good reliability, precise temperature control and high heat utilization rate, which can effectively improve the use efficiency of electric vehicle batteries and prolong the mileage of electric vehicles. management system. Background technique

[0002] At present, electric vehicles, as a new energy vehicle with reduced oil consumption, low pollution and low noise, are considered to be an important way to solve the energy crisis and environmental degradation. Like traditional internal combustion engine vehicles, electric vehicles also require thermal management, mainly including thermal management of the passenger compartment and thermal management of the power system. In the existing electric vehicle thermal management method, the passenger cabin is cooled by air conditioning, an...
