The invention provides a heat management energy recycling system for a fuel cell. The heat management energy recycling system comprises an electric pile heat dissipation pipeline and an air heater, the electric pile heat dissipation pipeline comprises a first water pump connected with the galvanic pile, a heating branch and a cooling branch which are connected with the first water pump, and a first electronic three-way valve which is respectively connected with the heating branch, the cooling branch and the galvanic pile, and the cooling branch is provided with a radiator and a plate heat exchanger; the air heater comprises a warm air pipeline and an air blower, the warm air pipeline comprises a second water pump, a second electronic three-way valve, a second PTC heater and a warm air core which are sequentially connected in series through pipelines, the warm air pipeline further comprises a heat exchange branch, the middle of the heat exchange branch is connected with the plate heat exchanger, and the two ends of the heat exchange branch are connected with the second electronic three-way valve and the warm air core respectively. The heat management energy recycling system has the beneficial effects that the heat dissipation system of the fuel cell is associated with the heating system of the vehicle, and the vehicle passenger compartment is heated by using the heat which needs to be abandoned by heat dissipation of the cooling liquid in the fuel cell, so that the utilization efficiency of the heat of the fuel cell is improved.
Description
technical field [0001] The invention relates to the field of heating systems for new energy vehicles, in particular to a fuel cell thermal management energy recovery and utilization system. Background technique [0002] A fuel cell vehicle is a vehicle powered by electricity generated by an on-board fuel cell device. The fuel used by the vehicle-mounted fuel cell device is high-purity hydrogen or hydrogen-containing reformed gas obtained by reforming hydrogen-containing fuel. A fuel cell is a high-efficiency power generation device that directly converts the chemical energy of fuel into electrical energy by electrochemical reaction without burning fuel. A large amount of heat is generated during the operation of the fuel cell system, which needs to be taken away by the cooling system in time, and at the same time, the temperature needs to be controlled to ensure the high efficiency of the fuel cell. At present, the common practice in the market is to control the heat dissi...
