This invention provides an integrated uniform temperature direct cooling battery heat exchange plate, comprising: a left
current collector, a right
current collector, a large harmonica tube, a small harmonica tube, a water inlet
pipe, a water outlet
pipe, and a temperature distribution plate; the left
current collector comprises: a left current collector
pipe, a left current collector shell, and a left current collector cover; the left current collector pipe is a hollow pipe closed at both ends; the inner surface of the left current collector shell is fitted onto the outer surface of the left current collector pipe and located on both sides of the first surface, the cross-sectional side of the left current collector shell being longer than the cross-sectional side of the left current collector pipe; the left current collector cover and the left current collector shell are fitted together facing each other; the left current collector pipe forms a first cavity; the left current collector shell, the first surface, and the left current collector cover form a second cavity; the left side of the small harmonica tube is closed and connected to a first pipe; the left side of the large harmonica tube is closed and connected to a second pipe. This invention's integrated uniform temperature direct cooling battery heat exchange plate is an integral current collector structure, shortening the pipe connection path, simplifying the structure, effectively reducing
frictional resistance, and achieving battery heat exchange.
