Abstract

The invention relates to the technical field of battery thermal management, in particular to a bottom plate liquid cooling battery module with honeycomb-shaped heat dissipation channels. The bottom plate liquid cooling battery module comprises cylindrical batteries, a liquid cooling plate and the honeycomb-shaped liquid cooling heat dissipation channels, the liquid-cooled plate is of a square structure, and the upper surface of theliquid cooling plate is provided with a plurality of circular grooves for inserting the bottoms of the cylindrical batteries. The plurality of honeycomb-shaped liquid cooling heat dissipation channels are fixed in the liquid cooling plate, the cooling liquid inlets and cooling liquid outlets at the two ends of the honeycomb-shaped liquid cooling heat dissipation channels penetrate through the end walls at the two ends of the liquid cooling plate and are communicated with the outside, and a cooling bottom plate matched with the liquid cooling plate in shape is arranged below the liquid cooling plate; each honeycomb-shaped liquid cooling heat dissipation channel comprises a plurality of hexagonal channels and straight channels, each hexagonal channel is of a hexagonal tubular structure, the straight channels are arranged among the hexagonal channels at intervals, and the opposite angles of the hexagonal channels in the horizontal direction are connected with the straight channels. According to the present invention, the flow path of the cooling liquid in the liquid cooling plate is increased through the changeable flow channels, and heat is better taken away.
