The utility model relates to the technical field of all-
terrain vehicle batteries, and particularly discloses a double-layer four-liquid-cooling-plate parallel liquid cooling mechanism of a
power battery, which comprises a battery module mechanism, a liquid cooling plate mechanism arranged at the lower end of the battery module mechanism and connected with a water inlet
pipe assembly, the water inlet
pipe assembly is connected with a water outlet
assembly, and the water outlet assembly is connected with a water pump. The liquid cooling plate mechanism is further connected with a water outlet
pipe assembly, the water outlet pipe assembly is connected with a water outlet assembly, and the battery module mechanism is further connected with a two-layer support plate; according to the utility model, a double-layer four-liquid-cooling-plate parallel
liquid cooling system mechanism is adopted, and the eight modules are divided into an upper layer and a lower layer by using the four liquid cooling plates, so that the battery cells can be uniformly cooled / heated at the same time, the
temperature difference between the battery cells is reduced, and the temperature consistency of the battery cells is ensured; the water inlet pipe assembly designed by the double-layer four-liquid-cooling-plate parallel
liquid cooling system mechanism can realize
shunting and converging of the cooling liquid when the
power battery is required to be cooled / heated, and ensures parallel work of the four liquid cooling plates.
