Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of computer heat dissipation equipment, and particularly relates to a water cooling head and a water cooling heat dissipation system. BACKGROUND

[0002] The water cooling heat dissipation system is a circulating water channel system formed by a combination of a radiator (a cooling fin), a cooling fan, a pipeline and a water pump, etc. The system uses the water pump to drive the heat dissipation liquid to rapidly take away the heat absorbed on the radiator and discharge the heat outside the mainframe box through the cooling fan. It can be seen that the water cooling heat dissipation system is more active and efficient than the traditional cooling fin heat dissipation, and is beneficial to use in high heat and high integration electrical devices. Therefore, the installation of the water cooling heat dissipation system in the mainframe box of the computer is becoming more and more popular.

[0003] The water cooling heat dissipation system of the prior art generally comprises a heat dissipation water row and a water cooling head, and a fan is installed on the heat dissipation water row. The water cooling head is arranged on a central processing unit (hereinafter referred to as CPU) of the computer, and the water cooling head is connected with the heat dissipation water row through inlet and outlet pipelines to form a circulating heat dissipation water channel, and the fan discharges the heat on the heat dissipation water row outside the mainframe box. Among them, the liquid supplement operation of the water cooling heat dissipation system is to open a liquid supplement hole on the heat dissipation water row and block the hole with a plug. When the liquid needs to be supplemented, the plug needs to be opened, and then the liquid is supplemented into the heat dissipation water row from the liquid supplement hole. Since the plug is generally connected with the liquid supplement hole through threads, after long-term use, metal powder particles left by the friction of the plug in the threads may exist, which may fall into the flow channel of the heat dissipation water row and cannot be found or cleaned. These metal powder particles will flow with the liquid and produce noise, which cannot be handled. SUMMARY

[0004] The purpose of the embodiment of the application is to provide a water cooling head and a water cooling heat dissipation system, which solve the technical problem that the water cooling heat dissipation system of the prior art is prone to noise.

[0005] To achieve the above purpose, the technical scheme adopted by the application is:

During liquid supplementing, the sealing plug on the water inlet joint can be removed, and the entire water cooling and heat dissipation system can be supplemented with liquid from the water inlet joint. In this way, on the one hand, a hole is not needed to be formed on the heat dissipation water row as a liquid supplementing hole, thereby effectively ensuring the integrity and sealing performance of the heat dissipation water row. On the other hand, one of the water inlet joints on the water cooling head is used as a liquid supplementing opening, and a sealing plug is used to replace the conventional nail plug for plugging, thereby effectively eliminating the metal powder particles left by the thread friction of the conventional nail plug in the liquid supplementing hole of the heat dissipation water row, and the noise problem caused by the liquid flowing in the flow channel.

[0012] The structure on the pump body is improved, one of the two water inlet joints is symmetrically arranged on the opposite sides of the pump body, and the other of the two water inlet joints is arranged adjacent to the water outlet joint on the same side of the pump body. In this way, the user can select any one of the water inlet joints as a conventional water inlet end according to the available space on the installation environment, and connect the pipeline thereto, thereby effectively adapting to the installation environment and improving the assembly flexibility.

[0013] In one embodiment, the two water inlet joints and the one water outlet joint are each provided with a flow direction identifier for indicating the liquid flow direction.

The water outlet connector on the water-cooled head is connected with the water inlet pipe, one of the two water inlet connectors is connected with the water outlet pipe, and the other water inlet connector is provided with the sealing plug. In this way, the two water inlet connectors on the water-cooled head can be selected by the user, one of which is connected with the water inlet pipe as a conventional water inlet end of the pump body, and the other one is used as a liquid supplement port, and the sealing plug is opened when liquid supplement is needed, and the liquid is supplemented into the pump body through the other water inlet connector. The structure of the heat dissipation water row is complete, and no hole is needed on the heat dissipation water row as a liquid supplement hole, so that the sealing property of the heat dissipation water row is effectively ensured. In addition, the traditional plug plug on the liquid supplement hole of the heat dissipation water row is eliminated, and the metal powder particles left by the thread friction in the liquid supplement hole, which flow in the flow channel with the liquid, can cause noise problems.

[0018] The structure of the fan combination is improved, the fan combination comprises a box body and a plurality of cooling fans arranged on the box body, a display module is arranged on one side of the box body, and a wire hiding groove is arranged on the other side of the box body. In this way, a plurality of cooling fans are integrated on the box body to cover the entire cooling water row, which is conducive to quickly removing the heat on the cooling water row and effectively ensures the cooling effect. The one side of the box body is provided with a large display module, which is conducive to displaying various patterns or dazzling colors, thereby improving the aesthetic and dazzling effects. The connection cables in each cooling fan on the box body can be collected in the wire hiding groove on the other side of the box body and processed.

[0019] Another improvement is made to the structure of the fan combination, the fan combination is mainly composed of a plurality of separate cooling fans adjacent to each other, each side of each cooling fan is provided with a display module, and the other side opposite to the display module is provided with a wire hiding groove, and each adjacent joint surface of each cooling fan is provided with a wire hole communicating with the wire hiding groove.

[0048] In order to make the technical problems to be solved, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

Thus, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is more than one or more, unless otherwise explicitly specified.

[0052] For the liquid supplement operation of the water cooling system, the conventional scheme is to open a liquid supplement hole on the water cooling water discharge and to block it with a nail plug. When liquid supplement is needed, the nail plug needs to be opened, and then liquid is supplemented into the water cooling water discharge from the liquid supplement hole. Since the nail plug is generally connected with the liquid supplement hole by screw thread, after long time use, metal powder particles left by friction of the nail plug in the screw thread can easily fall into the flow channel of the water cooling water discharge and cannot be found or cleaned. These metal powder particles will flow with the liquid and generate noise, which cannot be handled.

[0053] Herein, the embodiments of the present application provide a novel water cooling head and a water cooling system using the same, the structure of the water cooling head is redesigned, at least two water inlet joints are arranged on the water cooling head for user to select as liquid supplement ports, thereby solving the technical problem that noise is easily generated in the conventional water cooling system, which will be described in detail.

[0054] Please refer to Figure 1 , Figure 2 and Figure 3 , the water cooling head comprises a pump body 100, at least two water inlet joints 101 and one water outlet joint 102 are arranged on the pump body 100, the pump body 100 further comprises a motor 103, an impeller 1, a partition plate 2, a confluence plate 3, a sealing plug 4 and a heat absorbing plate 5.

[0055] The two water inlet joints 101 can be connected with water inlet pipes, and the water outlet joint 102 is connected with a water outlet pipe. The sealing plug 4 can be selectively installed on any one of the water inlet joints 101.

[0056] In this way, the two water inlet joints 101 are selected by the user, one is connected with the water inlet pipe as the conventional water inlet end of the pump body 100, and the other is used as the liquid supplement port, when liquid supplement is needed, the sealing plug 4 is opened, and then liquid is supplemented into the pump body 100 from the water inlet joint 101.

[0057] Preferably, as shown in Figure 3 , the sealing plug 4 can be a plug made of soft rubber material, which replaces the nail plug arranged on the liquid supplement hole of the conventional water cooling water discharge, which is beneficial to eliminate the metal powder particles left by the thread friction of the nail plug in the liquid supplement hole of the water cooling water discharge, and the noise problem caused by the metal powder particles flowing with the liquid in the flow channel.

[0058] For the internal structure of the pump body, please refer to Figure 2 , Figure 4 and Figure 5 , the partition plate 2 divides the interior of the pump body 100 into an upper cavity 104 and a lower cavity 105, the upper cavity 104 is in communication with the water outlet joint 102, the lower cavity 105 is in communication with the two water inlet joints 101, and the partition plate 2 is provided with a flow guide hole 21 for guiding the flow between the upper cavity 104 and the lower cavity 105.

[0059] The impeller 1 is arranged in the upper cavity 104, and the motor 103 is used to drive the impeller 1 to rotate in the upper cavity 104, thereby driving the liquid to be discharged from the water outlet joint 102.

[0060] The confluence plate 3 is arranged in the lower cavity 105, and the confluence plate 3 is provided with a flow collecting pipe 31 and a flow guide groove 32, the flow collecting pipe 31 is arranged in the middle of the upper surface of the confluence plate 3. The flow guide groove 32 is also formed on the upper surface of the confluence plate 3 and extends from the outer periphery of the flow collecting pipe 31 to the symmetrical two sides of the confluence plate 3, and the flow guide grooves 32 on the two sides are in communication with the flow guide hole 21 on the partition plate 2 in the pump body 100.

[0061] The two ends of the flow collecting pipe 31 are in communication with the two water inlet joints 101 respectively, and the bottom of the flow collecting pipe 31 is provided with a liquid outlet 33 penetrating through the confluence plate 3 and facing the heat absorption plate 5. It can be understood here that the liquid can enter the lower cavity 105 from any one of the water inlet joints 101 and can reach the confluence plate 3, and the flow collecting pipe 31 on the confluence plate 3 discharges the input liquid through the bottom liquid outlet 33 to the heat absorption plate 5.

[0062] The flow guide groove 32 is located outside the flow collecting pipe 31, and the flow guide groove 32 is used to guide the liquid flowing back from the heat absorption plate 5 to the flow guide hole 21 of the partition plate 2 and to the upper cavity 104. It can be seen that the entering liquid in the flow collecting pipe 31 and the output liquid on the flow guide groove 32 are separated on the confluence plate 3, and the confluence plate 3 plays a role of flow distribution for the inlet and outlet water paths in the interior of the pump body 100.

[0063] The heat absorption plate 5 is used to be arranged on the heat generating body. In this embodiment, the heat generating body can be preferably the CPU installed on the mainboard of the computer, and the heat absorption plate 5 can be preferably made of heat absorption copper plate, and the bottom of the heat absorption plate 5 is coated with silicone grease, so that the heat absorption plate 5 can better adhere to the CPU, thereby improving the heat absorption effect.

[0064] The heat absorption plate 5 is provided with a row of heat dissipation fins 51 in the middle area of the upper surface, and the row of heat dissipation fins 51 is arranged in order by a plurality of heat dissipation fins. In this embodiment, the plurality of heat dissipation fins are arranged in order in a matrix, and the matrix can be preferably adapted to the size of the CPU and corresponds to the position of the region with the largest heat generation in the center of the CPU.

[0065] The heat sink array 51 has a guide gap 52 for guiding liquid to the outer edge of the heat absorber plate 5. This can be understood as the presence of a guide gap 52 between adjacent heat sinks, which extends toward the outer edge of the heat absorber plate 5.

[0066] Compared with the prior art, the water cooling head provided in this embodiment has at least two water inlet connectors 101. One of the two water inlet connectors 101 can be used as a conventional water inlet for connection with the water inlet pipe; the other of the two water inlet connectors 101 can be used as a liquid replenishment port, thereby replacing the traditional structure of opening a liquid replenishment hole on the radiator and sealing it with a plug. During liquid replenishment, the sealing plug 4 on the water inlet connector can be removed, and liquid can be replenished to the entire water cooling system through the water inlet connector 101. In this way, on the one hand, it is not necessary to open a hole on the radiator as a liquid replenishment hole, effectively ensuring the integrity and sealing of the radiator. On the other hand, by using one water inlet connector 101 on the water cooling head as a liquid replenishment port and using a sealing plug 4 instead of a traditional plug for sealing, the metal powder particles left behind by the thread friction of the traditional plug in the liquid replenishment hole on the radiator are effectively eliminated, and the noise problem caused by these metal powder particles flowing with the liquid in the flow channel is eliminated.

[0067] Regarding the internal structure of the water cooling head, in this embodiment, the water cooling head divides the pump body 100 into an upper cavity 104 and a lower cavity 105 via a partition plate 2. The impeller 1 is located in the upper cavity 104, and the manifold 3 and heat absorber 5 are located in the lower cavity 105. The upper cavity 104 serves as the liquid outlet chamber and communicates with the water outlet connector 102, while the lower cavity 105 serves as the liquid inlet chamber and communicates with the two water inlet connectors 101. Utilizing the structure on the manifold 3, such as... Figure 5 As shown, the liquid F1 entering the pump body 100 from any inlet connector 101 flows through the outlet 33 of the manifold 31 to the heat absorber plate 5, rapidly carrying away the heat absorbed by the heat absorber plate 5. Then, it flows back from the heat absorber plate 5 to the guide groove 32 of the manifold 3, and then through the guide hole 21 on the partition plate 2 into the upper cavity 104. Finally, driven by the impeller 1, it is output from F2 through the outlet connector 102. In this way, the impeller 1 pressurizes the liquid that rebounds from the heat absorber plate 5 and flows back to the upper cavity 104 before outputting it, effectively reducing hydraulic loss and ensuring the heat dissipation effect of the water-cooled heat dissipation system.

[0068] For the structure on the pump body 100, please refer to one embodiment of this application. Figure 3 and Figure 6 One of the two inlet connectors 101 is symmetrically arranged on opposite sides of the pump body 100 with the outlet connector 102, and the other of the two inlet connectors 101 is arranged on the same side of the pump body 100 adjacent to the outlet connector 102.

[0069] In the embodiment, as shown in Figure 5 the first water inlet joint 101a is arranged on the same side of the pump body 100 adjacent to the water outlet joint 102; the second water inlet joint 101b is symmetrically arranged on the opposite sides of the pump body 100 and coaxially aligned. The second water inlet joint 101b and the water outlet joint 102 are connected with the pipelines (such as the water outlet pipe and the water inlet pipe on the heat dissipation water row) respectively communicating with the heat dissipation water row.

[0070] In this way, the user can select any one of the water inlet joints 101 as the regular water inlet end according to the available space on the installation environment, and connect the pipeline thereon, effectively adapt to the installation environment, and further improve the assembly flexibility.

[0071] Preferably, in the embodiment of the present application, please refer to Figure 6 , the flow direction identifier 106 for indicating the liquid flow direction is arranged on each of the two water inlet joints 101 and the water outlet joint 102.

[0072] Among them, the flow direction identifiers 106 on the two water inlet joints 101 are respectively the indication arrows of the flow direction to the inside of the pump body 100, and the flow direction identifier 106 on the water outlet joint 102 is the indication arrow of the flow direction to the outside of the pump body 100.

[0073] In this way, the user can intuitively distinguish the water inlet joints 101 and the water outlet joint 102, and further improve the installation accuracy and assembly efficiency.

[0074] In order to improve the liquid flow pressure in the water cooling head and increase the lift of the pump body 100, the internal structure of the pump body 100 is further improved. In an embodiment of the present application, please refer to Figure 2 , Figure 4 and Figure 5 , the pump body 100 further includes a booster plate 6 arranged between the confluence plate 3 and the heat absorbing plate 5. The booster plate 6 covers the heat dissipation fin row 51 of the heat absorbing plate, and the booster plate 6 is provided with a booster port 61 corresponding to the liquid outlet 33.

[0075] In the embodiment, as shown in Figure 4 and Figure 5As shown, the booster plate 6 covers the fin array 51, and the booster port 61 on the booster plate 6 boosts the liquid output from the liquid outlet 33 at the bottom of the manifold 31 to increase the flow rate, so that the liquid can reach the fin array 51 of the heat absorption plate 5 and be dispersed to the outer edge of the heat absorption plate 5 from each flow guide gap 52, so as to quickly take away the heat absorbed on the heat absorption plate 5; then, the liquid rebounds upward from the heat absorption plate 5, passes through the flow guide groove 32 into the upper cavity 104, and the impeller 1 in the upper cavity 104 rotates to boost the liquid flowing through it for the second time and then outputs from the water outlet connector. In this way, the hydraulic loss is effectively reduced, and the output water pressure and lift are increased, and the heat dissipation effect of the entire water-cooled heat dissipation system is improved.

[0076] For the booster structure on the booster plate 6, the booster port 61 on the booster plate 6 can be designed accordingly to boost the liquid flowing through the booster port 61. For the specific structure of the booster port 61, including but not limited to the following forms:

[0077] In an embodiment of the present application, the area of the booster port 61 on the booster plate 6 is smaller than the area of the liquid outlet 33 on the manifold 3, so as to boost the liquid output from the liquid outlet 33 of the manifold 31.

[0078] In another embodiment of the present application, under the premise of ensuring the flow output, the inner diameter of the booster port 61 on the booster plate 6 can be preferably set to gradually decrease from the liquid outlet 33 to the heat absorption plate 5. In this way, the booster port 61 is set as a converging port that gradually decreases in the direction of the heat absorption plate 5, thereby boosting the liquid flowing through it.

[0079] In a third embodiment of the present application, the booster port 61 on the booster plate 6 is set by combining the above two schemes to maximize the boosting effect.

[0080] In actual application, the manifold 3 and the heat absorption plate 5 are both installed in the lower cavity 105 of the pump body 100. Due to the dimensional tolerance in production and manufacturing, when the manifold 3 and the heat absorption plate 5 are installed on the pump body 100, their fixed positions are locked, and if there is a spacing tolerance between the manifold 3 and the heat absorption plate 5, it cannot be adjusted, resulting in that the upper and lower surfaces of the booster plate 6 cannot be in close contact with the manifold 3 and the heat absorption plate 5, respectively, the liquid will flow out of the gap formed by the dimensional tolerance, and the hydraulic loss will be caused.

[0081] In addition, since the booster plate 6 needs to cover the fin array 51 of the heat absorption plate 5, so that the liquid output from the booster port 61 can directly enter the fin array 51. However, the height of each fin in the fin array 51 on the heat absorption plate 5 is difficult to be uniform, and there are likely to be size defects, resulting in uneven upper surface of the fin array 51. When the booster plate 6 covers the fin array 51, local gaps are formed, and the flowing liquid will flow out of these local gaps, resulting in hydraulic loss, and even the liquid flows out without reaching the deep part of the flow guide gap 52, finally the heat on the heat absorption plate 5 cannot be completely taken away, affecting the heat dissipation effect.

[0082] It can be seen that the close fit between the bus plate 3, the booster plate 6 and the heat absorption plate 5 is particularly important. If there is a gap due to size tolerance, the flowing liquid will be lost, resulting in pressure loss, booster failure and affecting the heat dissipation effect.

[0083] Therefore, in an embodiment of the present application, the material of the booster plate 6 is improved. The booster plate 6 can be preferably made of soft rubber material, so that the whole or part of the booster plate 6 can be twisted and deformed.

[0084] In this way, the upper and lower surfaces of the booster plate 6 can better fill the gap tolerance and the concave and convex surface on the fin array 51, effectively improve the fit between the bus plate 3, the booster plate 6 and the heat absorption plate 5, ensure that the liquid can reach the deep part of the flow guide gap 52 between each fin, and maximize the heat absorbed by the heat absorption plate 5, thereby improving the heat dissipation effect.

[0085] In addition, in actual application, after the liquid enters the pump body 100 from any water inlet joint 101, it will directly reach the collecting pipe 31 of the bus plate 3 and be output from the liquid outlet 33, and then be boosted through the booster port 61 on the booster plate 6. In this process, the booster port 61 on the booster plate 6 and the liquid outlet 33 on the bus plate 3 must be accurately aligned to ensure the water output, otherwise it will easily cause blockage. However, after a long time of use, the booster plate 6 and the bus plate 3 are easy to be relatively displaced under the long-term impact of the liquid, resulting in that the booster port 61 on the booster plate 6 and the liquid outlet 33 on the bus plate 3 cannot be accurately aligned, affecting the water output.

[0086] Therefore, in another embodiment of the present application, please refer to Figure 7 and Figure 8 The booster plate 6 is further provided with a protruding positioning block 62, and the bottom of the bus plate 3 has a positioning groove 34 for embedding the positioning block 62.

[0087] In this embodiment, the upper end surface of the booster plate 6 is provided with a plurality of positioning blocks 62 which are arranged to avoid the booster port 61; correspondingly, the bottom of the bus plate 3 has a plurality of positioning grooves 34 which are the same in shape and number as the above-mentioned positioning blocks 62.

[0088] In this way, the positioning block 62 on the booster plate 6 is inserted into the positioning groove 34 at the bottom of the bus plate 3, thereby fixing the booster plate 6 at the bottom of the bus plate 3, which is conducive to ensuring that the booster port 61 on the booster plate 6 is accurately positioned corresponding to the liquid outlet 33 on the bus plate 3, effectively avoiding the displacement of the booster plate 6 to ensure the water output.

On the one hand, the structure of the heat dissipation water tank 300 is complete, and there is no need to open a hole on the heat dissipation water tank 300 as a liquid supplement hole, thereby effectively ensuring the sealing property of the heat dissipation water tank 300. On the other hand, the metal powder particles left in the liquid supplement hole due to the friction between the threads are eliminated, and the noise problem caused by the metal powder particles flowing in the flow channel along with the liquid is also eliminated.
