The invention discloses a heat dissipation module for
battery thermal management. The heat dissipation module comprises a top cover plate, a cooling plate and an outlet pipeline. The top cover plate is provided with
two fluid passages. The top cover plate and the outlet
pipe are respectively located at the upper and lower ends of the cooling plate. The cooling plate is intenrally provided with a fractal microchannel. The inlet of the fractal microchannel is connected with a fluid pipeline flowing through the pole lug, and the outlet of the fractal microchannel is connected with the outlet pipeline. The cooling plate and
lithium iron phosphate battery cells are alternately distributed, and the two sides of each
lithium iron phosphate battery cell are attached to the cooling plate. The temperature of the battery module can be accurately controlled, the temperature of the battery module is controlled within a safe range and the temperature distribution is uniform; and the heat dissipationmodule has a compact structure and is beneficial to realize the weight reduction of the whole vehicle.
