[0031] The traditional double-sided heat dissipation water-cooling plate has a structure of cover plate-brazing plate-main body-brazing plate-cover plate. The present application has a structure of first main body 1-brazing plate 3-second main body 2. Compared with the traditional structure, the present application saves materials and reduces the occupied space, and is suitable for areas with limited space.

[0032] The first flow channel 11 has a first water inlet 12 and a first water outlet 13, and the second flow channel 21 has a second water inlet 22 and a second water outlet 23. The first water inlet 12 and the second water inlet 22 together constitute a water inlet, and the first water outlet 13 and the second water outlet 23 together constitute a water outlet.

[0033] The brazing plate 3 is located between the first body 1 and the second body 2, and can separate the first flow channel 11 and the second flow channel 21. Thus, external cooling water enters from the water inlet and enters the first flow channel 11 and the second flow channel 21 respectively through the separation effect of the brazing plate 3.

[0034] like Figure 2 As shown, the first flow channel 11 is a continuous S-shaped structure, and the first flow channel 11 includes a first water inlet channel 111, a first cooling channel 112 and a first water outlet channel 113. One end of the first water inlet channel 111 is connected to the first water inlet portion 12, one end of the first water outlet channel 113 is connected to the first water outlet portion 13, and both ends of the first cooling channel 112 are respectively connected to one end of the first water inlet channel 111 away from the first water inlet portion 12 and one end of the first water outlet channel 113 away from the first water outlet portion 13;

[0035] After entering from the water inlet, the external cooling water flows into the first water inlet channel 111 through the first water inlet portion 12 , and then is transported to the first water outlet channel 113 through the first cooling channel 112 , and finally is discharged from the first water outlet portion 13 .

[0036] The first water inlet channel 111, the first cooling channel 112 and the first water outlet channel 113 each include two passages; external cooling water flows into the first water inlet channel 111 through the first water inlet portion 12, and is divided into two passages, flowing to the first cooling channel 112 and the first water outlet channel 113;

[0037] The first cooling channel 112 includes a first confluence portion 1121, a second confluence portion 1122, a third confluence portion 1123, a fourth confluence portion 1124 and a fifth confluence portion 1125 which are connected in sequence, and the first confluence portion 1121, the third confluence portion 1123 and the fifth confluence portion 1125 are arranged on the same side, and the second confluence portion 1122 and the fourth confluence portion 1124 are arranged on the same side and close to the water inlet;

[0038] The first confluence portion 1121 and the second confluence portion 1122 are connected via a first cooling segment, the second confluence portion 1122 and the third confluence portion 1123 are connected via a second cooling segment, the third confluence portion 1123 and the fourth confluence portion 1124 are connected via a third cooling segment, and the fourth confluence portion 1124 and the fifth confluence portion 1125 are connected via a fourth cooling segment;

[0039] The external cooling water flows into the first water inlet channel 111 through the first water inlet 12, and after being divided into two paths, it first converges at the first confluence 1121, and then divides into three paths through the first cooling section to converge at the second confluence 1122, and then divides into three paths through the second cooling section to converge at the third confluence 1123, and then divides into three paths through the third cooling section to converge at the fourth confluence 1124, and then divides into three paths through the fourth cooling section to converge at the fifth confluence 1125, and finally divides into two paths to enter the first water outlet channel 113, and is discharged from the water outlet.

[0040] like Figure 3 As shown, the second flow channel 21 includes a second water inlet channel 211, a second water outlet channel 212, a second cooling channel 213 and a third cooling channel 214. The second water inlet channel 211 is connected to the second water inlet portion 22, the second water outlet channel 212 is connected to the second water outlet portion 23, the second cooling channel 213 has a first water inlet end and a first water outlet end, the third cooling channel has a second water inlet end and a second water outlet end, the first water inlet end and the second water inlet end are both connected to the second water inlet channel 211, and the first water outlet end and the second water outlet end are both connected to the second water outlet channel 212;

[0041] After the external cooling water enters from the water inlet, it flows into the second water inlet channel 211 through the second water inlet part 22, and then splits in the second water inlet channel 211, entering the second cooling channel 213 and the third cooling channel 214 from the first water inlet end and the second water inlet end respectively, and then is output to the second water outlet channel 212 from the first water outlet end and the second water outlet end respectively, and finally is discharged to the water outlet through the second water outlet part 23.

[0042] The second water inlet channel 211 is connected with a first water inlet branch 2111 and a second water inlet branch 2112. The first water inlet branch 2111 is connected with the first water inlet end, and the second water inlet branch 2112 is connected with the second water inlet end.

[0043] The second water outlet channel 212 is connected with a first water outlet branch 2121 and a second water outlet branch 2122 . The first water outlet branch 2121 is connected with the first water outlet end, and the second water outlet branch 2122 is connected with the second water outlet end.

[0044] The second cooling channel 213 and the third cooling channel 214 are both U-shaped structures, and each includes two passages;

[0045] After the external cooling water flows into the second cooling channel 213 and the third cooling channel 214 respectively through the first water inlet branch 2111 and the second water inlet branch 2112 in the second water inlet channel 211, it is divided into two passages, and the cooling water flow direction is formed by the U-shaped structure, and finally converges at the first water outlet branch and the second water outlet branch respectively, and then passes through the second water outlet channel 212 and the second water outlet part 23 to be discharged to the outlet.

[0046] Working principle: External cooling water enters through the water inlet and is separated by the brazing plate 3 to form a split flow, which flows to the first water inlet 12 and the second water inlet 22 respectively. The cooling water flowing into the first water inlet 12 enters the first water inlet channel 111 and then passes through the first cooling channel 112 and the first water outlet channel 113, and is discharged from the first water outlet end to the water outlet. The first water inlet channel 111, the first cooling channel 112 and the first water outlet channel 113 all include two passages, and pass through the first cooling section, the second cooling section, the third cooling section and the fourth cooling section, which lengthens the cooling water path, expands the heat dissipation area, and effectively improves the heat dissipation efficiency;

[0047] The cooling water flowing into the second water inlet part 22 enters the second water inlet channel 211, is diverted by the first water inlet branch 2111 and the second water inlet branch 2112, and enters the second cooling channel 213 and the third cooling channel 214 respectively. The second cooling channel 213 and the third cooling channel 214 each include two passages, and the second cooling channel 213 and the third cooling channel 214 are both U-shaped structures. Then the cooling water in the second cooling channel 213 and the third cooling channel 214 enters the second water outlet channel 212 through the first water outlet branch 2121 and the second water outlet branch 2122 respectively, and finally flows to the water outlet through the second water outlet part 23 and is discharged; the second cooling channel 213 and the third cooling channel 214 expand the contact area between the heat-conducting medium and the device, effectively improve the heat dissipation efficiency, and at the same time increase the temperature uniformity of the heat dissipation, ensuring that the heat-conducting medium dissipates heat consistently in the second cooling channel 213 and the third cooling channel 214 areas.

[0048] The first main body 1, the brazing plate 3 and the second main body 2 are welded in sequence, which reduces the space occupied by the device, optimizes the size of the heat sink, saves materials, and is more convenient during welding and easy to assemble, so that it can be used in compact spaces. The first flow channel 11 and the second flow channel 21 have different shapes and densities. The first flow channel 11 is suitable for low-power and densely distributed devices, and the second flow channel 21 is suitable for high-power devices, thereby meeting the heat dissipation requirements of different power devices.

[0049] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
