Because the length of the runner is longer, a high-power water pump is required to drive the cooling water, and in order to avoid the overlarge temperature rise in the area close to the liquid outlet pipe, the cooling water needs a high flow rate, so that the power of the water pump is further increased. 4. The inner surface area of the plate type water cooling plate assembly can only reach 1.5 times of the area of the water cooling base, and the heat exchange efficiency is too low.
