As a power source for automobiles, they will become one of the important directions for the sustainable development of the automobile industry. Hydrogen fuel cells are the main power source for fuel cell vehicles. They are power generation devices that convert the chemical energy of hydrogen fuel into electrical energy. However, while the electric vehicle industry is developing rapidly, a series of outstanding problems have also been exposed. For example, the existing thermal management system performance of components such as batteries, electric drives and electronic controls is not ideal, resulting in serious heat accumulation in the operating environment. This has also been recognized as the main cause of the above-mentioned industrial difficulties. Therefore, in response to this problem, the existing heat generated in hydrogen fuel cell heavy trucks is cooled and dissipated by cooling it. On the one hand, the heat is reused by setting a circulation pipeline, such as the Chinese utility model with application number 202221056657.6, which proposes a hydrogen fuel cell heavy truck in-vehicle heat circulation device, including a fuel cell stack and a system pipeline, one end of the fuel cell stack is connected to a fuel cell water pump, the other end of the fuel cell stack is connected to an electromagnetic three-way valve for controlling the pipeline circulation, one end of the electromagnetic three-way valve is connected to a three-way connecting pipe, and the other end of the electromagnetic three-way valve is connected to a warm air controller, and the warm air controller is connected to a warm air radiator; the end of the fuel cell water pump is connected to a fuel cell radiator and an expansion water tank, and the fuel cell radiator is connected to the second three-way valve connecting pipe to form a circulation pipeline.
