The upper side plate 104 has four holes at its four corners. Two of the diagonal holes are protruding, and the other two are recessed, which are suitable for fixing and connecting the core plate assembly 401, facilitating the flow of refrigerant and water.

[0048] like Figures 1 to 5As shown, the core board assembly 401 includes several first core boards 402 and second core boards 407 arranged at intervals. The periphery of the first core board 402 and the second core board 407 are both raised. The four corners of the first core board 402 are sequentially provided with a first core board first inlet 403, a first core board second inlet 405, a first core board first outlet 406 and a first core board second outlet 404, wherein the first core board first inlet 403 and the first core board first outlet 406 are raised structures, and the first core board second inlet 405 and the first core board second outlet 404 are recessed structures. The four corners of the second core plate 407 are sequentially provided with a first inlet 408, a second inlet 410, a first outlet 411, and a second outlet 409. The second inlets 410 and 409 are protruding structures, while the first inlets 408 and 411 are recessed structures. The second inlets 410 and 409 of the second core plate 407 are welded to the second inlets 405 and 404 of the upper first core plate 402, thus sealing the second inlets 410 and 409 of the second core plate 407. Figure 5 As indicated by the arrows, the flow direction of the refrigerant or water in the second core plate 407 is from the first inlet 408 to the first outlet 411. The first inlet 408 and the first outlet 411 of the second core plate 407 are welded together with the first inlet 403 and the first outlet 406 of the lower first core plate 402, thus sealing off the first inlet 403 and the first outlet 406 of the lower first core plate 402.

Fins 412 are also sandwiched between the first core plate 402 and the adjacent second core plate 407. The outer surface of the fins 412 has several grooves suitable for liquid flow.

[0049] like Figure 1 , Figure 2 , Figure 8 , Figure 9As shown, a connector 201 is also fixedly installed on the mounting plate 101.

The upper section of the first conduit 301 is inserted into the conduit mounting hole 205, and the lower end of the first conduit 301 is located in the core plate assembly 401. The diameter of the first conduit 301 is smaller than the diameter of the conduit mounting hole 205, so that the refrigerant can flow back from the gap between the first conduit 301 and the conduit mounting hole 205 into the core plate assembly 401.

[0050] like Figure 1 , Figure 2 , Figure 6 , Figure 7As shown, a first partition 302 and a second partition 304 are fixedly installed sequentially from top to bottom within the core board assembly 401, dividing the core board assembly 401 into an upper core layer, a middle core layer, and a lower core layer. A second conduit 303 is vertically fixedly installed on the mounting plate 101, with its inlet fixedly installed at the flow channel 103 of the mounting plate. The second conduit 303 is sequentially fixedly installed on the first partition 302 and the second partition 304, and its bottom end communicates with the lower core layer. The bottom end of the first conduit 301 is fixedly installed on the first partition 302 and communicates with the middle core layer. The periphery of the first partition 302 is convex upwards. The four corners of the first partition 302 are provided with a first partition connecting hole 305, a first partition inlet 307, a first partition conduit hole 308, and a first partition outlet 306, respectively. The first partition connecting hole 305 and the first partition conduit hole 308 are convex structures, which facilitates connection to the first core plate 402 or the second core plate 407 located above. The first partition inlet 307 and the first partition outlet 306 are recessed structures, which facilitates connection to the first core plate 402 or the second core plate 407 located below. The liquid flow principle in the first partition 302 is the same as that in the first core plate 402 or the second core plate 407. The first partition conduit hole 308 includes two spaced-apart circular holes, which are used to insert the first conduit 301 and the second conduit 303, respectively. The second partition 304 has an upwardly protruding periphery. The four corners of the second partition 304 are provided with a second partition connection hole 309, a second partition inlet 311, a second partition conduit hole 312, and a second partition outlet 310, respectively. The second partition inlet 311 and the second partition outlet 310 are protruding structures to facilitate connection to the upper first core plate 402 or the second core plate 407. The second partition connection hole 309 and the second partition conduit hole 312 are recessed structures to facilitate connection to the lower first core plate 402 or the second core plate 407. The liquid flow principle in the second partition 304 is the same as that of the first core plate 402 or the second core plate 407. The second partition conduit hole 312 includes a circular hole for inserting the second conduit 303.

[0051] like Figure 1 , Figure 2As shown, a water pipe assembly is fixedly installed at the bottom end of the core board assembly 401. The water pipe assembly is connected to the core board assembly 401 and is suitable for water flow for heat dissipation. The water pipe assembly includes a lower side plate 501 and a base plate 502 arranged sequentially. Two holes are provided diagonally on the lower side plate 501 to facilitate water flow. One end of the base plate 502 has a hole corresponding to that of the lower side plate 501, and the other end of the base plate 502 has a horizontally arranged long groove. A water pipe pressure plate 503 is fixedly installed at the long groove. A round hole is provided on one side of the water pipe pressure plate 503, and an inlet pipe 505 is fixedly installed at the round hole. A gasket 504 is also fixedly installed on the base plate 502. One corner of the gasket 504 has an arc-shaped structure, which is suitable for directly fixing the outlet pipe 506 at the hole of the base plate 502.

[0052] The working principle of this utility model is as follows: the refrigerant flows through the refrigerant inlet 102 and the mounting plate 101 to the inlet of the second conduit 303, and then enters the lower core layer through the second conduit 303, and then flows back to the middle core layer. It flows upward through the bottom of the first conduit 301, sequentially through the connector 201 and the drying tank 202, and then flows back from the drying tank 202 to the connector 201. It then flows through the gap between the conduit mounting hole 205 of the connector 201 and the first conduit 301 to the upper core layer, and finally flows out from the refrigerant outlet on the mounting plate 101.

[0053] Water flows through the inlet pipe 505 into the lower core layer, middle core layer and upper core layer in sequence, and then flows back to the lower core layer in the reverse direction, and flows out through the outlet pipe 506.
