Description

Technical Field

[0001] The embodiments of the present invention relate to the field of cooling devices, and in particular to a water separation device. Background Art

[0002] With the rapid development of computer technology, the power of computers is also increasing; as the power of computers increases, the heat energy they generate is also increasing. Therefore, computers are usually equipped with air cooling devices or liquid cooling devices for heat dissipation.

[0003] The existing computer liquid cooling device uses a stainless steel square tube as a water supply channel, drills a row of holes on the square tube, welds a threaded joint to each hole to form a connection part for connecting the water distribution pipe together with the hole, and then fixes multiple water distribution pipes on each threaded joint to transmit the liquid heat dissipation medium to the area where heat dissipation is required. However, it is easy to generate debris when drilling holes on the square tube, and it is easy to generate welding slag at the welding joint. The debris and welding slag remain inside the square tube and are difficult to rinse clean. During use, the debris and welding slag flow with the fluid, which can easily cause damage to the liquid cooling device.

[0004] Therefore, how to avoid residual debris and welding slag during the assembly of the liquid cooling device and avoid damage to the liquid cooling device caused by such debris and welding slag has become a problem that needs to be solved urgently in the design and manufacturing process of the liquid cooling device. Summary of the invention

[0005] The purpose of the embodiment of the present invention is to provide a water separation device, which can prevent debris and welding slag from remaining during the assembly of a liquid cooling device and avoid damage to the liquid cooling device caused by such debris and welding slag.

[0006] To solve the above problems, an embodiment of the present invention provides a water distribution device, including: a panel, a water tank and a water distribution pipe; the panel is provided with a plurality of connecting parts, the water distribution pipe is fixed on the panel through the connecting parts, the panel covers the water tank to form a water supply channel, and the water supply channel is connected to the water distribution pipe.

[0007] Compared with the prior art, the water supply channel of the present invention is assembled by a panel and a water tank, rather than a square tube in the prior art. Therefore, when making the water supply channel, the panel and the water tank with the connecting part can be thoroughly cleaned first, and then the panel and the water tank are covered to form the water supply channel, thereby reducing debris and welding slag inside the water distribution device and avoiding damage to the liquid cooling device caused by this.

[0008] Preferably, in the water distribution device, the connection part is a threaded through hole, the water distribution pipe is provided with an external thread, and the water distribution pipe is fixed to the panel through the external thread and the threaded through hole. By providing a threaded through hole on the panel and an external thread on the water distribution pipe, the water distribution pipe is fixed to the threaded through hole of the panel through threads, so that there is no need to weld the joint for connecting the water distribution pipe, thereby effectively saving the joint cost, welding labor cost, and reducing the risk of leakage.

[0009] Preferably, in the water distribution device, there are two water tanks, one of which is a return tank and the other is a supply tank. Since the water tank is provided with a supply tank and a return tank, the panel covers both the supply tank and the return tank, which can reduce the installation space of the liquid cooling system using the water distribution device.

[0010] Preferably, in the water diversion device, the connection part includes a first connection part connected to the return tank and a second connection part connected to the water supply tank, and the number of the first connection parts is the same as the number of the second connection parts.

[0011] Preferably, in the water distribution device, the return water tank and the water supply tank are arranged on two opposite sides of the panel.

[0012] Preferably, in the water distribution device, the water tank includes two openings arranged opposite to each other in the extension direction of the water supply channel, and two end plates respectively covering the two openings, and through holes communicating with the water supply channel are formed on the two end plates.

[0013] Preferably, the water distribution device further comprises: two joints, and the two joints are respectively connected to the through holes.

[0014] Preferably, the water distribution device further comprises: a plug, which is fixed to the panel via at least one connecting portion.

[0015] Preferably, in the water distribution device, the panel covers the water tank by welding.

[0016] Preferably, in the water distribution device, the water tank includes a body that forms a groove, and the panel covers the groove of the body to form a water supply channel, and in the extension direction of the water supply channel, the cross section of the groove perpendicular to the extension direction of the water supply channel gradually increases. Such an arrangement can effectively reduce the flow pressure at one end of the water supply channel, so that the flow pressure of each water distribution pipe is similar.

[0025] As can be seen from the background technology, the existing computer liquid cooling device uses a stainless steel square tube, drills a row of holes on the square tube, welds a threaded joint on each hole, and then fixes multiple water distribution pipes on each threaded joint to transfer the liquid heat dissipation medium to the area where heat dissipation is required. However, when drilling holes on the square tube, it is easy to generate debris, and welding joints are easy to generate welding slag. The debris and welding slag remain inside the square tube and are difficult to rinse clean. During use, the debris and welding slag flow with the fluid, which can easily cause damage to the liquid cooling device.

[0026] In order to solve the above problem, an embodiment of the present invention provides a water distribution device, including: a panel, a water tank and a water distribution pipe; the panel is provided with a plurality of connecting parts, the water distribution pipe is fixed to the panel through the connecting parts, the panel covers the water tank to form a water supply channel, and the water supply channel is connected to the water distribution pipe. In the water distribution device provided by the present invention, the water supply channel is assembled by the panel and the water tank, and is not a square tube in the prior art. Therefore, when making the water supply channel, the panel provided with the connecting part and the water tank can be fully cleaned first, and then the covering panel and the water tank are covered to form the water supply channel, so as to reduce the debris and welding slag inside the water distribution device and avoid the damage of the liquid cooling device caused by it.

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are provided to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented.

[0028] Figure 1 A schematic diagram of the structure of a water distribution device provided in Embodiment 1 of the present invention; Figure 2 This is an exploded view of the water distribution device provided in Example 1 of the present invention.

[0029] See also Figure 1 and Figure 2 The water distribution device provided in this embodiment includes: a panel 100 and a water tank 200. The panel 100 is provided with a plurality of connection parts, which are threaded through holes 110. The water tank 200 is provided with a body 202 that forms a groove. The body 202 includes a first opening 203 and a second opening 204 that are arranged at opposite ends of a water supply channel 201. The panel 100 covers the groove of the body 202 to form the water supply channel 201. Furthermore, in this embodiment, the water distribution device can also be equipped with a first end plate 410, a first joint 510, a second end plate 420 and a second joint 520, the first end plate 410 is provided with a first through hole 411 connected to the water supply channel 201, the first joint 510 is connected to the first through hole 411, the second end plate 420 is provided with a second through hole (not shown) connected to the water supply channel 201, the second joint 520 is connected to the second through hole, and several water distribution pipes 300 are provided with external threads 310, and the water distribution pipes 300 are fixedly connected to the threaded through holes 110 through the external threads 310. In addition, in this embodiment, a plug 600 is also provided, and when a threaded through hole 110 does not need to be externally connected to the water distribution pipe 300, the plug 600 is fixed to the threaded through hole 110 on the panel 100 to prevent the fluid from flowing out.

[0030] By providing a plurality of threaded through holes 110 on the panel 100 and providing the water distribution pipe 300 with external threads 310, the water distribution pipe 300 can be fixed to the panel 100 through the external threads 310 and the threaded through holes 110, without the need for welding threaded joints, which can effectively save manufacturing costs; at the same time, since the water distribution pipe 300 is fixed to the threaded through holes 110 through the external threads 310, a portion of the water distribution pipe 300 is fixed inside the panel 100, which reduces the length of the exposed portion of the water distribution pipe 300 and reduces the space occupied by the water distribution device during installation. In addition, the threaded joints are omitted, which further reduces the space occupied by the water distribution device during installation.

[0031] In addition, see Figure 1, the panel 100 and the water tank 200 are fixed together by welding, and the water tank 200 can also be provided with a welding edge 205 bent and extended from the main body 202. Overlapping and welding the welding edge 205 and the panel 100 can enhance the welding strength; it can be understood that the first end plate 410 and the second end plate 420 can also be fixedly connected to the water tank 200 by welding; the first end plate 410 and the first joint 510, as well as the second end plate 420 and the second joint 520 can be integrally formed, and can also be fixed together by welding; the thickness of the panel 100 is 3mm-8mm (mm, millimeter), and in this embodiment, the thickness of the panel 100 is 5mm, and the threaded through hole 110 is also provided with a chamfer at one end of the water distribution pipe 300, and the chamfer is used to install an O-ring. The O-ring is arranged between the panel 100 and the water distribution pipe 300, which can enhance the sealing of the connection between the panel 100 and the water distribution pipe 300; the 5mm panel 100 can also prevent the panel 100 from deforming during welding.

[0032] During installation, the water distribution device can be placed vertically or horizontally.

[0033] When the water tank 200 is a water supply tank and the first end plate 410 is lower than the second end plate 420 in the vertical direction, the fluid flows from the first joint 510 through the first opening 203 and then flows into the water supply channel 201 (that is, the water supply channel 201 formed by the groove of the body 202 of the water tank 200 covered by the panel 100), and then flows out through the water distribution pipe 300. The second joint 520 is equipped with an exhaust valve, which can be used to remove the gas inside the water distribution device; or, the fluid flows from the second joint 520 through the second opening and then flows into the water supply channel 201, and then flows out through the water distribution pipe 300. In addition, the first joint 510 is equipped with a drain valve for discharging liquid when the water distribution device is maintained. The fluid can pass through the first through hole 411 and then flow out from the first joint 510.

[0034] When the water tank 200 is a water supply tank and the first end plate 410 and the second end plate 420 are located at the same horizontal position, the fluid flows from the first joint 510 through the first opening 203 into the water supply channel 201 and then flows out through the water distribution pipe 300. At the same time, the fluid can also flow out from the second joint 520 after passing through the second through hole.

[0035] When the water tank 200 is a return tank and the first end plate 410 is lower than the second end plate 420 in the vertical direction, the fluid flows from the water distribution pipe 300 through the water supply channel 201, flows through the first opening 203, passes through the first through hole 411, and then flows out from the first joint 510; the second joint 520 is equipped with an exhaust valve, which can be used to remove the gas inside the water distribution device.

[0036] When the water tank 200 is a return water tank and the first end plate 410 and the second end plate 420 are located at the same horizontal position, the fluid flows from the water distribution pipe 300 through the water supply channel 201, flows through the first opening 203, passes through the first through hole 411, and then flows out from the first joint 510, or the fluid passes through the second through hole and then flows out from the second joint 520.

[0037] In this embodiment, the threaded through holes 110 are arranged in a straight line. It is understandable that the threaded through holes 110 of the present invention are not limited to a straight line arrangement. The threaded through holes 110 can be arranged accordingly at the positions of the panel 100 corresponding to the water supply channels 201. More preferably, the threaded through holes 110 are arranged at equal intervals.

[0038] Figure 3 This is an exploded view of the water distribution device provided in the second embodiment of the present invention.

[0039] See also Figure 3 The water distribution device provided in the second embodiment of the present invention is substantially the same as the water distribution device provided in the first embodiment, and the difference from the first embodiment is that the cross-sectional area of ​​the groove of the body 202 (in the direction perpendicular to the extension of the water supply channel 201) gradually increases in the extension direction of the water supply channel 201 from the second opening 204 to the first opening 203. The cross-sectional area of ​​the first opening 203 in the direction perpendicular to the extension of the water supply channel 201 is greater than the cross-sectional area of ​​the second opening 204 in the direction perpendicular to the extension of the water supply channel 201. In detail, the width of the first opening 203 (in the X-axis direction as shown in the figure) is greater than the width of the second opening 204 (in the X-axis direction as shown in the figure), and the width of the groove of the main body 202 (in the extension direction perpendicular to the water supply channel 201) gradually increases in the extension direction of the water supply channel 201 from the second opening 204 to the first opening 203 (in the X-axis direction as shown in the figure). The present invention is not limited to this, as long as the cross-sectional area of ​​the groove of the main body 202 increases, such as gradually increasing in the height direction (in the Y-axis direction as shown in the figure), or increasing in both the height direction (in the X-axis direction as shown in the figure) and the width direction (in the Y-axis direction as shown in the figure).

[0040] When the water tank 200 is a water supply tank, the first end plate 410 is lower than the second end plate 420 in the vertical direction (from the second opening 204 to the first opening 203), and the fluid flows from the first joint 510 through the first opening 203 and then flows into the water supply channel 201, and then flows out through the water distribution pipe 300. The second joint 520 is equipped with an exhaust valve for connection.

[0041] At this time, when the water distribution device is in the lower water supply mode (the fluid flows from the first joint 510 located below through the first opening 203 and then flows into the water supply channel 201), since the first opening 203 with a larger width is the fluid inlet, the flow rate of the end of the water supply channel 201 close to the first opening 203 is larger, and under the diversion effect of multiple water distribution pipes 300, the flow rate of the end of the water supply channel 201 close to the second opening 204 (that is, the end away from the first opening 203) is smaller. The above-mentioned arrangement reduces the cross-sectional area of ​​the groove of the body 202 (in the extension direction perpendicular to the water supply channel 201) along the flow direction of the fluid, and the cross-section of the water supply channel 201 is reduced along the water flow direction, which can reduce the flow velocity difference at both ends of the water tank 200, thereby reducing the pressure difference of the water outlet from each threaded through hole 110 connected to the water distribution pipe 300, so that the water volume of each water distribution pipe 300 is more uniform.

[0042] When the water tank 200 is a water supply tank, the first end plate 410 is higher than the second end plate 420 in the vertical direction (from the second opening 204 to the first opening 203), or the first end plate 410 and the second end plate 420 are at the same horizontal position, the fluid flows from the first joint 510 through the first opening 203 and then flows into the water supply channel 201, and then flows out through the water distribution pipe 300.

[0043] At this time, when the water distribution device is in the upper water supply mode (the fluid flows from the first joint 510 located at the top through the first opening 203 and then flows into the water supply channel 201), since the first opening 203 with a larger width is the fluid inlet, the end of the water supply channel 201 close to the first opening 203 has a larger flow rate, and under the diversion effect of multiple water distribution pipes 300, the end of the water supply channel 201 close to the second opening 204 (that is, the end away from the first opening 203) does not discharge fluid. The above-mentioned arrangement reduces the cross-sectional area of ​​the groove of the body 202 (in the extension direction perpendicular to the water supply channel 201) along the flow direction of the fluid. The cross-section of the water supply channel 201 is reduced along the water flow direction, which can reduce the flow velocity difference at both ends of the water tank 200, thereby reducing the pressure difference of the water outlet from each threaded through hole 110 connected to the water distribution pipe 300, so that the amount of water outlet from each water distribution pipe 300 is more uniform.

[0044] When the water tank 200 is a return water tank, the first end plate 410 is higher than the second end plate 420 in the vertical direction (from the second opening 204 to the first opening 203), or the first end plate 410 and the second end plate 420 are at the same horizontal position, the fluid flows from the water distribution pipe 300 into the water supply channel 201 and then flows out of the first joint 510.

[0045] At this time, when the water distribution device is in the upper return water mode (the fluid flows from the water supply channel 201 through the first opening 203 and then flows into the first joint 510 located above), since the first opening 203 with a larger width is the fluid outlet, the end of the water supply channel 201 close to the first opening 203 has a larger flow rate, and the water flows into the water supply channel 201 from the multiple water distribution pipes 300, and the end of the water supply channel 201 close to the second opening 204 (that is, the end away from the first opening 203) does not discharge the fluid. The above-mentioned arrangement increases the cross-sectional area of ​​the groove of the body 202 (in the extension direction perpendicular to the water supply channel 201) along the flow direction of the fluid, and the cross-section of the water supply channel 201 increases along the water flow direction, which can reduce the flow velocity difference at both ends of the water tank 200, thereby reducing the pressure difference of the return water of each threaded through hole 110 connected to the water distribution pipe 300, so that the amount of water returned by each water distribution pipe 300 is more uniform.

[0046] When the water tank 200 is a return tank, the first end plate 410 is lower than the second end plate 420 in the vertical direction (from the second opening 204 to the first opening 203), the fluid flows from the water distribution pipe 300 into the water supply channel 201 and then flows out of the first joint 510. The second joint 520 is equipped with an exhaust valve.

[0047] At this time, when the water distribution device is in the lower water return mode (the fluid flows from the water supply channel 201 through the first opening 203 and then flows into the first joint 510 located below), since the first opening 203 with a larger width is the fluid outlet, the end of the water supply channel 201 close to the first opening 203 has a larger flow rate, and the water flows into the water supply channel 201 from multiple water distribution pipes 300. The end of the water supply channel 201 close to the second opening 204 (that is, the end away from the first opening 203) is equipped with an exhaust valve, and no fluid flows out. The above-mentioned arrangement increases the cross-sectional area of ​​the groove of the body 202 (in the extension direction perpendicular to the water supply channel 201) along the flow direction of the fluid. The cross-sectional area of ​​the water supply channel 201 increases along the water flow direction, which can reduce the flow velocity difference at both ends of the water tank 200, thereby reducing the pressure difference of the return water of each threaded through hole 110 connected to the water distribution pipe 300, so that the amount of water returned from each water distribution pipe 300 is more uniform.

[0048] Figure 4 This is a schematic diagram of the structure of the water distribution device provided in Example 3 of the present invention.

[0049] See also Figure 4 The water distribution device provided in the third embodiment of the present invention is substantially the same as the water distribution device provided in the first embodiment, and the difference from the first embodiment is that in the water distribution device, there are two water tanks, one of which is a return tank 210 and the other is a supply tank 220; the panel 100 covers both the return tank 210 and the supply tank 220. Fixing the return tank 210 and the supply tank 220 on the same panel can effectively reduce the space occupied during installation.

[0050] In addition, the panel 100 may also include a first panel covering the return tank 210 and a second panel covering the supply tank 220, and then a plurality of mounting plates with threaded holes are welded between the first panel and the second panel for installation and fixation, which can also effectively reduce the space occupied during installation.

[0051] Preferably, in the above water distribution device, the threaded through hole 110 includes a first threaded through hole connected to the return tank 210 and a second threaded through hole connected to the water supply tank 220, and the number of the first threaded through holes is the same as the number of the second threaded through holes. This ensures that the number of water distribution pipes connected to the return tank 210 is the same as the number of water distribution pipes connected to the water supply tank 220.

[0052] Figure 5 This is a schematic diagram of the structure of the water distribution device provided in Example 4 of the present invention.

[0053] See also Figure 5 The water distribution device provided in the fourth embodiment of the present invention is substantially the same as the water distribution device provided in the third embodiment, and differs from the first embodiment in that, in the water distribution device, the return water tank 210 and the water supply tank 220 are arranged on opposite sides of the panel 100 .

[0054] Since the fluid inside the cooling device will carry heat when it flows into the return water tank 210 after absorbing heat after flowing out through the water supply tank 220, the return water tank 210 and the water supply tank 220 are arranged on opposite sides of the panel 100, which can increase the distance between the return water tank 210 and the water supply tank 220, thereby preventing the fluid from transferring heat to the water supply tank 220 when the fluid absorbs heat and flows into the return water tank 210.

[0055] Figure 6 This is a schematic diagram of the structure of the water distribution device provided in Example 5 of the present invention.

[0056] See also Figure 6 The water distribution device provided in the fifth embodiment of the present invention is substantially the same as the water distribution device provided in the second embodiment, and is different from the second embodiment in that there are two water tanks, one of which is a return tank 210 and the other is a supply tank 220; the panel 100 covers the return tank 210 and the supply tank 220 at the same time, or the panel 100 includes a first panel covering the return tank 210 and a second panel covering the supply tank 220, and then the first panel and the second panel are welded together.

[0057] Fixing the water return tank 210 and the water supply tank 220 on the same panel can effectively reduce the occupied space during installation.

[0058] Figure 7 This is a schematic diagram of the structure of the water distribution device provided in Example 6 of the present invention.

[0059] See also Figure 7 The water distribution device provided in the sixth embodiment of the present invention is substantially the same as the water distribution device provided in the fifth embodiment, and differs from the fifth embodiment in that, in the water distribution device, the return water tank 210 and the water supply tank 220 are arranged on opposite sides of the panel 100 .

[0060] Since the fluid inside the cooling device still carries heat when it flows into the return water tank 210 after absorbing heat after flowing out through the water supply tank 220, the return water tank 210 and the water supply tank 220 are arranged on opposite sides of the panel 100, which can increase the distance between the return water tank 210 and the water supply tank 220, thereby preventing the fluid from transferring heat to the water supply tank 220 when the fluid absorbs heat and flows into the return water tank 210.

[0061] In addition, it is worth noting that the above-mentioned embodiments 5 and 6 only show the fixed positions between the water supply tank 220 and the return tank 210 and the panel 100. Among them, in the direction from the first interface 510 to the second interface 520, the cross-section of the groove of the water supply tank 220 (in the extension direction perpendicular to the water supply channel) gradually increases. Of course, in another feasible modification implementation, the cross-section of the groove of the water supply tank 220 (in the extension direction perpendicular to the water supply channel) can also be gradually increased in the direction from the second interface 520 to the first interface 510. Similarly, in the direction from the third interface 530 to the fourth interface 540, the cross-section of the groove of the return tank 210 (in the extension direction perpendicular to the water supply channel) gradually increases. Of course, in another feasible modification implementation, the cross-section of the groove of the return tank 210 (in the extension direction perpendicular to the water supply channel) can also be gradually increased in the direction from the fourth interface 540 to the third interface 530.

[0062] It can be understood by those skilled in the art that the above-mentioned embodiments are specific examples of the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention. Any person skilled in the art can make their own changes and modifications without departing from the spirit and scope of the present invention, so the protection scope of the present invention shall be based on the scope defined in the claims.
