The wave-peak flow guide area 42 on the first cooling unit A is arranged in a staggered manner with the corresponding wave-peak flow guide area 42 on the second cooling unit B, and a shunt channel is formed between the two. The curved surface structure design makes the water flow generate more vortex and turbulence on the surface of the filler, which helps to increase the time of water film staying on the surface of the filler sheet and optimize the heat exchange process.
[0022] Specifically, the retention area 41 is a convex structure on one side of the flow channel and a concave structure on the other side, and in the first cooling unit A and the second cooling unit B, a first flow channel 1 and a second flow channel 2 are formed between the adjacent two retention units 4 at equal distances, and the first flow channel 1 and the corresponding second flow channel 2 are arranged in a corresponding staggered manner.
[0023] A group of annular retention grooves 411 are arranged on the retention area 41, and the retention grooves 411 are interval arranged along the vertical direction. Based on the equal-interval arrangement structure of the flow channel, the designed retention grooves 411 ensure that the cooling water is not easy to splash during the flow process, and the time of the cooling water staying is prolonged. The width of each filler sheet unit is the same, and the equal-distance fluid channel is formed, which improves the overall heat dissipation rate of the filler sheet.
[0024] Specifically, in the first cooling unit A, two planar bonding areas 3 are arranged at each retention area 41, and are arranged on both sides of the retention area 41.
[0025] In the second cooling unit B, a bonding area 3 is arranged at the middle of each retention area 41. In the unit structure, two positioning points 5 are arranged in the bonding area 3 and the second flow channel.
[0026] The bonding area 3 is a plane convex structure on one side of the flow channel and a plane concave structure on the other side.
[0027] Based on the structural design of the bonding area 3 and the positioning point 5, the positioning and bonding connection between two filler sheets can be facilitated, and the connecting surface between the concave-convex bonding structures can divide the water film and play a guiding role.
[0028] In use, the plurality of filler sheets are stacked and vertically placed, the first flow channel 1 and the second flow channel 2 between two adjacent filler sheets are combined to form a water-gas flow path, and the shunt passage between the retention units 4 between two adjacent filler sheets is combined to form a shunt passage to realize drainage.
[0029] When stacked and installed, the protruding side of the positioning point 5 on one filler sheet is matched with the recessed side of the positioning point 5 on another filler sheet to realize positioning, and the bonding area 3 on one filler sheet is bonded with the back side of the flow channel on another filler sheet at the corresponding position.
