The invention discloses a vehicle-mounted battery and electric control cooling system based on liquid hydrogen vaporization cold energy utilization, and belongs to a hydrogen energy automobile heat dissipation system. According to the invention, the heat exchanger is arranged in front of the vehicle-mounted vaporizer, so that the liquid hydrogen fuel fully exchanges heat with circulating water in the cooling system in the heat exchanger before vaporization, and the cooled circulating water can be used for cooling heating parts such as a vehicle-mounted battery and an electric controller. Therefore, the cooling system based on liquid hydrogen vaporization cold energy utilization can effectively reduce the cooling power of the vehicle-mounted cooling system, improve the driving mileage of the hydrogen energy vehicle, and achieve the purposes of energy conservation and consumption reduction.
