The first water radiator pipe 131, the second water radiator pipe 132 and the third water radiator pipe 133 can be selected as flat pipes, and metal fins can be arranged between the water radiator pipes to ensure good heat dissipation effect.

[0037] Figure 2 and Figure 3 are cross-sectional views of the water-cooled radiator according to an embodiment of the present utility model at two different positions, wherein Figure 2 the cross-sectional position is parallel to the extending direction of the water radiator pipe group 13,Figure 3 The cross-section position is perpendicular to the extending direction of the water discharge pipe group 13. Figure 4 and Figure 5 shows the structure of the water cooling head 2. Referring to Figures 2 - 5 , the water cooling head 2 has a circulation space which is communicated with the water discharge pipe group 13. The circulation space has a water inlet chamber 241, a heat absorption chamber 242, an impeller chamber 243 and a water outlet chamber 244 which are communicated in sequence. One end of the second water discharge pipe 132 is communicated with the first water tank 11, and the other end is communicated with the water inlet chamber 241. One end of the third water discharge pipe 133 is communicated with the water outlet chamber 244, and the other end is communicated with the second water tank 12. For example, referring to the water cooling head 2 includes a housing 21, a base 22 and a pump 23. One side of the base 22 is attached to a heat generating component such as a graphics card. The base 22 has a heat dissipation structure 221 which is arranged in the heat absorption chamber 242. The base 22 transfers the heat of the heat generating component to the heat dissipation structure 221, and the heat dissipation structure 221 conducts the heat into the coolant in the heat absorption chamber 242. The base 22 can be made of a copper structure or other materials with good heat conduction performance. The heat dissipation structure 221 can be, for example, a plurality of protruding heat dissipation pin columns, heat dissipation fins or other structures.

[0038] The housing 21 has a partition 213 which has an opposite first side and second side, wherein the first side is the side far from the base 22 and the second side is the side close to the base 22. The partition 213 has a first communication hole 2131 and a second communication hole 2132 which are arranged at intervals. The first communication hole 2131 communicates the water inlet chamber 241 and the heat absorption chamber 242, and the second communication hole 2132 communicates the heat absorption chamber 242 and the impeller chamber 243. The pump 23 is installed on the housing 21 and has an impeller 231. The impeller 231 can be a centrifugal impeller 231 or other feasible impeller 231 forms. The impeller 231 is installed in the impeller chamber 243 and is used to provide the power for the circulating flow of the coolant in the water cooling radiator. The water inlet chamber 241, the impeller chamber 243 and the water outlet chamber 244 are arranged on the first side of the partition 213 and are arranged side by side basically. The heat absorption chamber 242 is arranged on the second side of the partition 213. This setting method makes full use of the transverse space and uses the height space of the cold row pipe group to accommodate the water pump 23 and each chamber of the water cooling head 2, which is beneficial to reducing the overall thickness of the water cooling head 2 and further reducing the overall thickness of the water cooling radiator.

[0039] When the water-cooled radiator is working, the impeller 231 rotates to drive the coolant to circulate in a closed flow path between the first water tank 11 - the second water discharge pipe 132 - the water inlet chamber 241 - the heat absorption chamber 242 - the impeller chamber 243 - the water outlet chamber 244 - the third water discharge pipe 133 - the second water tank 12 - the first water discharge pipe 131 - the first water tank 11. When the coolant that has absorbed heat in the heat absorption chamber 242 flows to the third water discharge pipe 133 and the first water discharge pipe 131, it can dissipate the heat to the surrounding environment, and then the coolant with reduced temperature flows to the water-cooled head 2 via the first water tank 11 and the second water discharge pipe 132, and can continuously dissipate heat from the heating element.

[0043] Referring to Figure 8 , the pump housing 232 has a pump sealing groove 2322, and the pump sealing groove 2322 is arranged on the surface of the pump housing 232 opposite to the bottom wall of the pump installation groove 2113. When the pump housing 232 is arranged in the pump installation groove 2113, the pump sealing groove 2322 surrounds the opening 2114, and a pump sealing ring 233 is provided between the pump sealing groove 2322 and the bottom wall of the pump installation groove 2113. The pump sealing ring 233 can be a rubber sealing ring, a silica gel sealing ring, or other types of sealing rings. The bottom surface of the pump installation groove 2113 presses the pump sealing ring 233 into the pump sealing groove 2322, thereby realizing the sealing of the impeller chamber 243.

[0044] Optionally, the pump housing 232, the upper housing 211, and the lower housing 212 can be sequentially connected by the same connecting piece. This can simplify the structure and assembly process of the water cooling radiator, and at the same time is beneficial to reducing the thickness of the water cooling radiator. In one embodiment, referring to Figure 5, the pump housing 232 has a first connection hole 2323, the upper housing 211 has a second connection hole 2116, and the lower housing 212 has a third connection hole 2123.

After the pump 23, the upper housing 211, and the lower housing 212 are placed in place at predetermined positions, screws, pins, or other connecting members can be used to pass through the first connection hole 2323, the second connection hole 2116, and the third connection hole 2123 in sequence to fix the pump 23, the upper housing 211, and the lower housing 212 to each other.

[0045] Referring to Figure 7 , in this embodiment, the lower housing 212 has a boss 2121, and the boss 2121 protrudes from the second side of the partition plate 213. A receiving groove 2122 is recessed in the middle of the boss 2121. After the lower housing 212 is connected to the base 22, the inner wall of the receiving groove 2122 and the base 22 enclose and define a heat absorption chamber 242. One end of the first communication hole 2131 extends to the first side of the partition plate 213, and the other end extends to the receiving groove 2122. Optionally, the first communication hole 2131 can extend at least to the side wall of the receiving groove 2122.

The flow dividing plate 25 is disposed in the receiving groove 2122 and located between the base 22 and the partition plate 213, and is used to guide the flow of the coolant in the heat absorption chamber 242. The flow dividing plate 25 divides the heat absorption chamber 242 into a heat exchange area 2421 and a diversion area 2422. The heat exchange area 2421 corresponds to the base 22, and when the coolant flows to the heat exchange area 2421, it contacts the heat dissipation structure 221 of the base 22 to achieve heat exchange. The diversion area 2422 is disposed on the side of the flow dividing plate 25 close to the bottom of the receiving groove 2122 and corresponds to the second communication hole 2132. The coolant in the diversion area 2422 can enter the impeller chamber 243 through the second communication hole 2132. The flow dividing plate 25 has a collecting port 251 and a diversion port 252 which are spaced apart. The collecting port 251 and the diversion port 252 penetrate the flow dividing plate 25 along the thickness direction. The collecting port 251 guides the coolant flowing to the first communication hole 2131 to the heat exchange area 2421, and the diversion port 252 guides the coolant in the heat exchange area 2421 to the diversion area 2422.

Figure 11 is a cross-sectional view of the water-cooling head 2, where Figure 11 the cross-section is parallel to the partition plate 213, and the cross-sectional position passes through the first communication hole 2131 of the lower housing 212, the flow dividing plate 25, and the diversion area 2422. Referring to Figure 10 andFigure 11 , the flow splitter 25 further includes at least two flow collecting grooves 253, the number of the flow collecting grooves 253 corresponds to the first communication holes 2131, and the first flow collecting grooves 253 correspond to the first communication holes 2131 one by one. One end of each flow collecting groove 253 faces a corresponding one of the first communication holes 2131 (for example, refer to Figure 7 ), and the other end extends to the flow collecting port 251. Thus, the plurality of flow collecting grooves 253 collect the coolant flowing in from different first communication holes 2131 into the flow collecting port 251, and the coolant flows from the flow collecting port 251 to the heat exchange area 2421.

[0048] The diversion port 252 can be arranged at the edge of the flow splitter 25 to form a long and narrow groove shape. Refer to Figure 11 , when the flow splitter 25 is installed in the receiving groove 2122, the side surface of the flow splitter 25 abuts against the side wall of the receiving groove 2122, and a long and narrow gap is formed between the diversion port 252 and the side wall of the receiving groove 2122. The flow collecting port 251 is closer to the middle of the flow splitter 25 than the diversion port 252. When the coolant flows in from the flow collecting port 251, it is close to the middle of the heat exchange area 2421, then fully contacts the heat dissipation structure 221 of the base 22 to absorb heat, and then flows into the diversion area 2422 from the diversion port 252 located at the edge of the heat exchange area 2421. Optionally, there can be at least two diversion ports 252. For example, one diversion port 252 can be arranged on each of the opposite sides of the flow splitter 25.

[0049] Optionally, refer to Figure 7 、 Figure 8 and Figure 10, the housing 21 further includes an impeller cover 214. The impeller cover 214 includes a support plate 2141 and positioning columns 2142 connected to the support plate 2141. The support plate 2141 is disposed in the receiving groove 2122 and is located between the bottom of the receiving groove 2122 and the flow dividing plate 25. The flow dividing plate 25 can press the support plate 2141 against the bottom of the receiving groove 2122 to fix the impeller cover 214. The shape of the support plate 2141 can match the receiving groove 2122, and the side wall of the receiving groove 2122 can limit the support plate 2141 to prevent the support plate 2141 from shaking or rotating in the receiving groove 2122. The positioning columns 2142 protrude from the support plate 2141, pass through the second communication hole 2132 and extend into the opening 2114. One end of the positioning column 2142 extending into the opening 2114 has a lower positioning hole 2143. The impeller 231 has a rotating shaft 2311, and the lower end of the rotating shaft 2311 is inserted into the lower positioning hole 2143 for positioning, thereby ensuring the stability of the impeller 231 during rotation. Further, the pump housing 232 may have an upper positioning hole, and the upper positioning hole is coaxially arranged with the lower positioning hole 2143. The upper end of the rotating shaft 2311 can be inserted into the upper positioning hole. Thus, the upper positioning hole and the lower positioning hole 2143 can cooperate to achieve good positioning of the rotating shaft 2311. The position of the support plate 2141 corresponding to the second communication hole 2132 also has a water passing hole 2144 opposite to the second communication hole 2132. The coolant in the heat absorption chamber 242 can enter the impeller chamber 243 through the water passing hole 2144 and the second communication hole 2132.

[0050] Optionally, the support plate 2141 has a positioning block 2145, and the flow dividing plate 25 has a positioning groove 254 at a position corresponding to the positioning block 2145. Inserting the positioning block 2145 into the positioning groove 254 can achieve positioning between the support plate 2141 and the flow dividing plate 25. Further optionally, referring to Figure 7 , Figure 10 and Figure 11 , the positioning groove 254 is opened on the side of the flow dividing plate 25 opposite to the confluence port 251, and the shape of the positioning groove 254 is different from the shape of the side where the confluence port 251 is located. When the support plate 2141 and the flow dividing plate 25 are not assembled in the predetermined direction, the protruding positioning block 2145 cannot be inserted into the positioning groove 254 and abuts against the top surface of the flow dividing plate 25, which can play an anti-mistake role and avoid the wrong assembly direction between the support plate 2141 and the flow dividing plate 25.

[0051] The water-cooled radiator according to the embodiment of the present utility model has a water block 2 disposed in the hollow portion 134 of the water-cooled row. The housing 21 has a partition 213. The water inlet chamber 241, the impeller chamber 243, and the water outlet chamber 244 of the water block 2 are disposed on the first side of the partition 213, and the heat absorption chamber 242 is disposed on the second side of the partition 213. The impeller 231 is installed in the impeller chamber 243. The partition 213 has a first communication hole 2131 and a second communication hole 2132 that are spaced apart. The first communication hole 2131 communicates the water inlet chamber 241 and the heat absorption chamber 242, and the second communication hole 2132 communicates the heat absorption chamber 242 and the impeller chamber 243. The heat dissipation structure 221 of the base 22 is disposed in the heat absorption chamber 242. Thus, the arrangement of the water block 2 makes full use of the space in the thickness direction of the water-cooled row to arrange multiple chambers, reduces the overall thickness of the water block 2, and further reduces the overall thickness of the water-cooled radiator, facilitating the installation of the water-cooled radiator in a narrow space and expanding the applicable range of the water-cooled radiator.

For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
