This invention discloses a nested serpentine channel liquid cooling plate and its battery thermal management system, belonging to the field of energy storage battery thermal management technology. The liquid cooling plate has a double-inlet, double-outlet serpentine flow channel inside, forming two parallel coolant flow paths to shorten the heat transfer path and improve temperature uniformity. A battery thermal management system includes a battery module composed of multiple square batteries and at least one liquid cooling plate, which is nested between the battery cells. Preferably, for a module composed of 20 square batteries, only three liquid cooling plates are used, respectively arranged on both sides and in the middle of the module, achieving a compact configuration of "one cooling plate cooling two battery cells". More preferably, the liquid cooling plate adopts an inlet / outlet direction of left-up-right-down and right-up-left-down, with a coolant mass flow rate of 1 g / s and an inlet temperature of 25°C. Experimental results show that at an ambient temperature of 45℃ and a discharge rate of 2C, the battery module's highest temperature is 28.75℃, the maximum temperature difference is 2.17℃, the voltage drop is 229.31Pa, and the comprehensive performance evaluation index PEC reaches 4.02. This invention significantly reduces system complexity, manufacturing costs, and flow resistance while ensuring efficient heat dissipation and excellent temperature uniformity, making it suitable for large-scale lithium iron phosphate energy storage modules.
