A water guide groove 14 is arranged at the communication part of the water storage chamber 11 and the water pump chamber 12, and a second water homogenizing grid 141 is arranged on the water guide groove 14; the fluid medium flowing out from the water outlet of the water pump forms vortex in the water storage chamber 11, and the second water-homogenizing grid 141 of the water guide groove 14 disperses the fluid medium and moves towards all directions in the water storage chamber 11, so that the fluid medium is uniformly distributed.
The water diversion member 13 is provided with a first water-balancing grid 131 at the joint of the water inlet of the water pump and the heat dissipation row 4, and the strip-shaped bodies of the first water-balancing grid 131 are staggered and distributed in a cross manner with the outlets of the flat pipes; the combination of the water pump and the heat dissipating rows 4 affects the distribution of water flow to reduce heat dissipating efficiency, and the first water balancing grid 131 is provided to eliminate the influence of water flow distribution and improve heat dissipating efficiency.
