The usual method is to pass the coolant into the battery cooling plate, circulate it in the battery cooling plate, and then take away the heat generated by the battery when it is working. In order to provide a sufficient range for pure electric buses, a large number of car batteries are required, and the battery cooling plates and pipelines need to be arranged around the car batteries accordingly; therefore, in the process of developing new models or modifying old models, the problem of insufficient available space is often encountered when designing battery cooling devices. There is also a need to leave assembly space between the various electrical parts for wiring harnesses, pipelines and other components, making the problem of insufficient design or modification space more serious.
