The utility model discloses a parallel
shunting type liquid cooling plate, comprising a liquid cooling substrate, the surface of the liquid cooling substrate is provided with a flow channel
pipe, the flow channel
pipe comprises a main flow channel
pipe, the main flow channel pipe is connected in series with a plurality of parallel
shunting pipes, the other end of the main flow channel pipe is provided with two
branch flow channel pipes, and the two
branch flow channel pipes are connected in series. A main body collecting pipe is arranged at the
tail end of the runner pipe on the liquid cooling substrate, and is connected with radiating fins; the five flow channels at the liquid inlet pipe orifice are connected in parallel for
shunting, the pressure drop of the
system can be reduced, and the parallel structure enables the cooling liquid to be more uniformly distributed among the battery monomers through shunting and parallel flowing, so that the
temperature difference among the battery packs is reduced, the
temperature difference is greatly reduced, and the heat dissipation efficiency of the
battery pack is improved by utilizing the
advantage of good heat dissipation effect of the parallel structure. And meanwhile, due to the slender flow channel structure design, the flow speed is increased, the structure is optimized and reinforced through the heat dissipation effect, and the heat dissipation efficiency is fully improved.
