DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solutions and advantages of the present specification clearer, the technical solutions of the present specification will be described clearly and completely below in combination with specific embodiments of the present specification and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present specification, but not all the embodiments. Based on the embodiments in the present specification, all other embodiments obtained by those skilled in the art without making any creative efforts fall within the scope of protection of the present specification.

[0049] Generally, a water pipe is connected to a water-cooled head through a water nozzle and connected to a water-cooled row through an inlet and outlet port of the water-cooled row. Limited by the limited space inside the case, the distribution of electronic components on the mainboard is often dense. Taking a CPU as an example, a memory is usually arranged near the CPU. The connection position of the water-cooled head and the water pipe is often located below the side surface of the water-cooled head, which is close to the electronic components, which also means that the connection position is close to the mainboard.

[0050] When there are a large number of electronic components on the mainboard, it is obviously not desirable to directly open a path on the surface of the mainboard for the water pipe to pass through. To solve this problem, designers usually use a clever method - designing the water nozzle in an L shape. Through this unique L-shaped structure, the flow direction of the cooling liquid can be effectively changed, so that the water pipe between the water nozzle and the radiator can bypass the electronic components on the mainboard, avoiding potential conflicts between the two, thereby ensuring the stability and safety of the water-cooled radiator.

[0051] In a water-cooled radiator, the connection point of the water pipe and the water-cooled row is usually the inlet and outlet of the water-cooled row, and its specific position is the short side of the water-cooled row, as shown in Figure 1

[0052] Figure 1 The structure of the water-cooled radiator is shown in the figure. It can be seen that the lower surface of the water-cooled head is arranged on the heat source, the water-cooled row is arranged on the top of the case, the water-cooled head and the water pipe are connected through the water nozzle, and the water nozzle is arranged on the side surface of the water-cooled head. The water pipe is connected to the inlet and outlet of the water-cooled row, and the outlet is arranged on the short side of the water-cooled row. It can be seen that in the case where the water pipe is not bent, there is no way to connect the water nozzle and the inlet and outlet of the water-cooled row.

[0053] Even if the inlet and outlet are arranged on the short side of the water-cooled row, in the case where the flow direction of the cooling liquid at the connection between the water nozzle and the water pipe is perpendicular to the mainboard, the flow direction of the cooling liquid at the connection between the water nozzle and the water pipe is often inconsistent with the flow direction of the cooling liquid at the connection between the water pipe and the water-cooled row, which leads to the need for the water pipe to be bent to change the flow direction of the cooling liquid. It can be seen that the above-mentioned situation requires the water pipe to be bent. Therefore, the resistance of the cooling liquid flowing at the bending position increases, resulting in a local pressure that is too high at the bending position of the water pipe, the material deteriorates quickly, and the service life of the water pipe is inevitably affected.

[0054] Based on this, the present application provides a water-cooled radiator, by connecting one end of the water pipe to the heat dissipation module near the heat exchange module, and the other end to the heat exchange module near the heat dissipation module on the side away from the heat source, to ensure that in the case where there are many electronic components on the mainboard, the connection module connecting the heat dissipation module and the heat exchange module does not need to be bent to connect the two components.

[0055] The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0056] ​The present specification provides a water-cooled radiator, which can be used for heat dissipation of electronic components, such as CPU, GPU, memory bar, motherboard chipset, power supply unit, etc. The radiator can also be used for heat dissipation of any one or more of electronic devices, such as server, medical imaging equipment, broadcast and communication equipment, etc. In the embodiments of the present specification, for the convenience of understanding, only the water-cooled radiator used for heat dissipation of CPU is taken as an example to illustrate the specific technical solutions. As shown in Figure 2A

[0057] Figure 2A The present specification provides a water-cooled radiator. As shown in the figure, the water-cooled radiator is arranged in the case, and includes a heat exchange module 1, a connecting module 2 and a heat dissipation module 3. The heat exchange module 1 is used to transfer the heat of the heat source to the cold liquid, and the electronic component is usually the heat source, so the heat exchange module 1 is arranged on the electronic component, and the bottom surface of the heat exchange module 1 is connected with the heat source.

[0058] The heat dissipation module 3 is used to cool the cold liquid in the water channel, so that it changes from high-temperature liquid to low-temperature liquid again. The heat dissipation module 3 is usually arranged at the top of the case, and the water-cooled row with a fan arranged thereon is taken as an example to illustrate the heat dissipation module 3 in the figure.

[0059] The connecting module 2 is used to connect the heat exchange module 1 and the heat dissipation module 3. The connecting module 2 can usually be a first water pipe 21, and the number of the first water pipe 21 is usually two, one of which is used to transfer the cold liquid from the heat dissipation module 3 to the heat exchange module 1, and the other is used to transfer the cold liquid from the heat exchange module 1 to the heat dissipation module 3.

[0060] ​In addition, the heat exchange module 1 can include a water cooling head 11 and a water nozzle 12, one end of the water nozzle 12 is connected with the water cooling head 11, the other end is connected with the connecting module 2, the connecting position of the water nozzle 12 and the connecting module 2 is the first position, the first position is located on the designated side of the heat exchange module 1, the designated side is the side with the shortest distance between the first position and the second position among the sides of the heat exchange module 1, and the distance between the first position and the lower bottom surface of the heat exchange module 1 is greater than the preset first distance threshold. The first distance threshold can be a specific value, such as 5mm, 7mm, 10mm, etc., or a proportion corresponding to the thickness of the water cooling head 11, such as 1 / 2 of the thickness of the water cooling head 11, 2 / 3 of the thickness of the water cooling head 11, etc. The specific first distance threshold can be set as needed, and this specification does not limit it. The thickness of the water cooling head 11 is the distance between the upper and lower bottom surfaces of the water cooling head 11, and the lower bottom surface of the water cooling head 11 is in contact with the heat source. In this way, the cold liquid flows out from the side of the heat exchange module 1 closest to the heat dissipation module 3, that is, the designated side, which can ensure that the heat exchange module 1 and the heat dissipation module 3 can be connected using a shorter water pipe to a certain extent, avoiding the problem that a too long water pipe occupies a large space in the case, is not beautiful enough, and is easy to collide with electronic components in the case, causing safety hazards, thereby ensuring the stability and safety of the water cooling radiator.

[0061] At the same time, the connecting module 2 is in communication with the heat dissipation module 3 at the second position, and the second position is located on the outer surface of the heat dissipation module 3 close to the heat exchange module 1. In this way, the cold liquid flows into the area on the outer surface of the heat dissipation module 3 close to the heat exchange module 1, which can further ensure that the heat exchange module 1 and the heat dissipation module 3 can be connected using a shorter water pipe, and further ensure the beauty and safety of the water cooling radiator. Taking the water cooling row 31 shown in the figure as an example, the second position can be located on the long side of the water cooling row 31 close to the heat exchange module 1.

[0062] It should be noted that the above-mentioned inflow and outflow process of the cold liquid is described by taking the cold liquid flowing from the heat exchange module to the heat dissipation module as an example. The cold liquid can also flow from the heat dissipation module to the heat exchange module. The flow direction in the flow process can be referred to the description of the flow direction in the above-mentioned embodiments, and this specification does not repeat it.

[0063] In order to more conveniently describe the structure of the water cooling radiator, this specification also provides a structure schematic diagram as shown in Figure 2B .

[0064] Figure 2B The structure schematic diagram of the water cooling radiator provided by this specification can be seen that the water cooling radiator includes three modules, namely the heat exchange module 1, the connecting module 2 and the heat dissipation module 3. Similar to the above-mentioned embodiment, Figure 2A , Figure 2BThe heat dissipation module 3 is still taken as an example of the water cooling radiator. As shown in the figure, the connection module 2 is connected to the heat exchange module 1 at a first position, which is located on the side of the heat exchange module 1 closest to the specified side of the heat dissipation module 3 and is located on the upper part of the specified side. Among them, the first position is located on the upper part of the specified side, which means that the distance between the first position and the lower bottom surface of the heat exchange module is greater than the preset first distance threshold.

[0065] Among them, the heat exchange module can be a minimum cuboid containing the water cooling head and the water nozzle, and the specified side is the side corresponding to the minimum cuboid containing the heat exchange module 1.

[0066] The above is only an example of the connection module 2, i.e., the first water pipe 21 does not bend at all, but in fact, taking the distance between the first position and the second position and the plane where the mainboard is located as an example, limited by the limited space inside the case, the first position and the second position are often located on both sides of the plane where the mainboard is located. Even if the first position and the second position are located on the same side of the plane where the mainboard is located, the distance from the first position to the plane where the mainboard is located is not the same as the distance from the second position to the plane where the mainboard is located. Therefore, when the water cooling radiator is deployed in the case, the connection module 2 will usually have some bends. Based on the above situation, the present specification also provides a water cooling radiator as shown in Figure 2C .

[0067] Figure 2C The structure diagram of the water cooling radiator provided by the present specification contains three modules: the heat exchange module 1, the connection module 2, and the heat dissipation module 3. As shown in the figure, the connection module 2 connecting the heat exchange module 1 and the heat dissipation module 3 has some bends, but compared with the radiator shown in Figure 1 , the length and bending angle of the corresponding bending part are smaller, the resistance of the bending part to the flow of the cooling liquid is also smaller, and the local pressure is also smaller than the water pipe in Figure 1 , so the service life is correspondingly prolonged.

[0068] Based on Figure 2A , Figure 2B and Figure 2CThe water-cooled radiator comprises a heat exchange module, a heat dissipation module and a connecting module. The connecting module is connected to the heat exchange module at a first position and connected to the heat dissipation module at a second position. By setting the first position on the heat exchange module close to the heat dissipation module and setting the second position on the heat dissipation module close to the heat exchange module, the heat exchange module and the connecting module can be connected through a shorter connecting module. By setting the first position on the side of the heat exchange module away from the heat source, the connecting module can avoid collision or friction with obstacles near the heat source, thereby avoiding the situation that the connecting module needs to bend a large angle to pass through the obstacles, ensuring the service life of the connecting module and avoiding safety hazards.

[0069] Further, one end of the water nozzle 12 is connected to the connecting module 2 at the first position, and the other end is connected to the water-cooled head 11 at the third position. In the aforementioned schematic diagram, the third position is located on the side of the water-cooled head 11 away from the heat source. However, in fact, most users use a water-cooled head 11 whose connection position with the water nozzle 12 is located on the side of the water-cooled head 11 close to the heat source. Based on the above situation, the present specification also provides a heat exchange module 1 as shown in the following figure. Figure 3A

[0070] Figure 3A The structure schematic diagram of the heat exchange module provided by the present specification is shown in the following figure. As can be seen, the heat exchange module 1 comprises a water-cooled head 11 and a water nozzle 12. In the figure, the water-cooled head 11 is taken as a cuboid structure for example. As can be seen, the connection position between the water-cooled head 11 and the water nozzle 12 is located on the side of the water-cooled head 11 close to the heat exchange module 1, that is, the third position where the water-cooled head 11 and the water nozzle 12 are connected is located on the side of the water-cooled head 11 close to the heat exchange module 1.

[0071] The water nozzle 12 can comprise three components. The first component 121 is used to connect with the water-cooled head 11. The second component 122 is used to connect the first component 121 and the third component 123. The third component 123 is used to connect with the first water pipe 21. That is, the first component 121 is connected to the first water pipe at the first position. One side of the second component 122 is connected to the first component 121, and the other side is connected to the third component 123. The third component 123 is connected to the water-cooled head 11 at the third position. The distance between the third position and the lower bottom surface of the water-cooled head 11 is less than a preset second distance threshold. Similar to the first distance threshold, the second distance threshold can be a specific value, such as 5mm, 7mm, 10mm, etc., or a proportion corresponding to the thickness of the water-cooled head 11, such as 1 / 2 of the thickness of the water-cooled head 11, 1 / 3 of the thickness of the water-cooled head 11, etc. The thickness of the water-cooled head 11 is the distance between the upper and lower bottom surfaces of the water-cooled head 11, and the lower bottom surface of the water-cooled head 11 is in contact with the heat source.​

[0072] Based on the same idea, the present specification also provides a partial schematic view of a water-cooled radiator as shown in Figure 3B .

[0073] Figure 3B A partial structural schematic view of a water-cooled radiator is provided in the present specification. The view includes a heat exchange module 1 and a part of a connecting module 2. It can be seen that a water nozzle 12 is connected to a water-cooled head 11 at a third position and connected to a first water pipe 21 at a first position. The third position is on the water-cooled head 11, and the first position is on the side of a smallest cuboid (not shown in the figure) containing the heat exchange module 1.

[0074] Furthermore, in order to more accurately describe the structure of the water nozzle 12, the present specification also provides a water nozzle 12 as shown in Figure 4A , Figure 4B and Figure 4C .

[0075] Figure 4A A structural schematic view of a water nozzle is provided in the present specification. It can be seen that a first component 121 and a third component 123 are hollow cylindrical structures, and a second component 122 is a hollow cuboid structure. The hollow structures are flow channels corresponding to the respective components. The flow channels corresponding to the first component 121, the second component 122, and the third component 123 form the flow channel of the water nozzle 12. At the same time, the first component 121 is perpendicular to the second component 122, and the third component 123 is also perpendicular to the second component 122. For each of the first component 121, the second component 122, and the third component 123, the flow direction of the cold liquid in the component is along the central axis of the component or in the positive or negative direction.

[0076] Taking the case where the bottom surface of the second component 122 is parallel to the bottom surface of the heat exchange module 1, the first component 121 and the third component 123 are respectively connected to the two opposite sides of the outer surface of the cuboid, and the distance between the connection position of the first component 121 and the second component 122 and the bottom surface of the second component 122 is different from the distance between the connection position of the second component 122 and the third component 123 and the bottom surface of the second component 122. That is, the distance between the first position and the bottom surface of the second component 122 is different from the distance between the third position and the bottom surface of the second component 122.

[0077] Figure 4A Taking the case where the second component 122 is a cuboid structure as an example, but in fact, the second component 122 can also be a cylindrical structure, as shown in Figure 4B .

[0078] Figure 4B A structural schematic view of a water nozzle is provided in the present specification. As Figure 4ASimilarly, the first component 121 and the third component 123 are hollow cylindrical structures, the difference being that the second component 122 is a hollow cylindrical structure.

[0079] Figure 4C This is a structural diagram of the faucet provided in this instruction manual. Figure 4A Similarly, the first component 121 and the third component 123 are hollow cylindrical structures, and the second component 122 is a hollow cuboid structure. The first component 121 and the third component 123 are respectively connected to two opposite sides of the outer surface of the second component 122. The difference is that the first component 121 is not perpendicular to the second component 122, and the third component 123 is also not perpendicular to the second component 122. Furthermore, the first component 121 and the third component 123 are not parallel to each other.

[0080] Obviously, the flow direction of the coolant in the first component 121 and the third component 123 is different from the flow direction of the coolant in the second component 122. However, the flow direction of the coolant in the first component 121 and the flow direction of the coolant in the third component 123 are less than a preset specified angle. This ensures that the angle at which the coolant flows out of the water cooling head 11 does not deviate significantly from the angle at which the coolant flows out of the water nozzle 12. This ensures that when the flow direction of the coolant from the water cooling head 11 is similar to the flow direction of the coolant at the inlet of the heat dissipation module 3, the first water pipe 21 does not need to undergo significant bends to change the flow direction of the coolant, further ensuring the service life of the connection module 2, i.e., the first water pipe 21. The specified angle can be 20°, 30°, 45°, etc., and the specific angle value can be set as needed; this specification does not impose any limitations on this.

[0081] certainly, Figure 4C The explanation is based solely on the example that the first component 121 and the third component 123 are not parallel, that is, the angle between the central axis of the first component 121 and the central axis of the second component 122 is different from the angle between the central axis of the third component 123 and the central axis of the second component 122. However, in reality, the first component 121 and the third component 123 included in the faucet 12 can be parallel components. In other words, the flow direction of the coolant in the first component 121 can be the same as the flow direction of the coolant in the third component 123.

[0082] Based on the above description of the water nozzle and water block, in order to more clearly describe the positional relationship between the first and third positions, this manual provides the following: Figure 4D The water tap shown.

[0083] Figure 4DThe first position and the third position provided in the present specification are illustrated by taking the first component 121 connecting the first water pipe 21 and the third component 123 connecting the water cooling head 11 as examples. The first position can be point A in the figure or point B in the figure. Point A in the figure is the middle position of the overlapping part of the first water pipe 21 and the first component 121 after the first water pipe 21 is connected to the first component 121, that is, point A is located on the specified side of the smallest cuboid containing the water cooling head, the second component, the third component and part of the first component. Point B in the figure is the middle point of the connecting part of the edge of the first component 121 and the water pipe, that is, point B is located on the specified side of the smallest cuboid containing the entire water nozzle and the water cooling head. Similarly, the third position can be point C in the figure or point D in the figure.

[0084] In addition, the material of the water nozzle 12 can generally be a plastic material, and the corresponding process can generally be an injection molding process. That is, the water nozzle 12 in the present specification can be made of plastic by injection molding process. Of course, the corresponding material of the water nozzle 12 can also be metal, ceramic, composite material (such as carbon fiber), graphite, etc. The specific material used to make the water nozzle 12 can be set as needed, and the present specification does not limit this.

[0085] However, in the case of a plastic water nozzle 12, due to the current process, it is generally not possible to make the aforementioned hollow water nozzle 12 with the flow channel in it being bent twice at one time. In this case, a preferred solution is to first make a water nozzle 12 that contains the first component 121, the second component 122 and the third component 123, but the bottom surface of one side of the second component 122 is an open structure, as shown in Figure 5A

[0086] Figure 5A The structure of the water nozzle provided in the present specification is shown in the figure. As an example, the bottom surface of the second component 122 of the water nozzle 12 is parallel to the bottom surface of the water cooling head 11, the bottom surface of one side of the second component 122 of the water nozzle 12 is an open structure, and a groove 1222 is provided in the open structure. Therefore, in addition to the body 1221 of the second component 122, the second component 122 also includes a sealing sub-component 1223 and a fixing sub-component 1224 (not shown in the figure).

[0087] The shape of the sealing sub-component 1223 and the shape of the groove 1222 are matched, so that after the sealing sub-component 1223 is fixed in the groove 1222, the second component body 1221 can be sealed, avoiding the situation that the open structure of the second component body 1221 leaks gas and / or liquid in the flow channel.

[0088] ​In addition, the sealing sub-component 1223 is fixed in the groove 1222 by the fixing sub-component. In the figure, the sealing sub-component 1223 is illustrated as including a pressing plate 12241 and a fastener 12242. The sealing sub-component 1223 is fixed in the groove 1222 by placing the sealing sub-component 1223 in the groove 1222, aligning the pressing plate 12241 with a connecting hole provided on the body of the second component 122, and finally fixing the sealing sub-component 1223 in the connecting hole.

[0089] Of course, the sealing sub-component 1223 and the fixing sub-component 1224 described above are only illustrative examples. The fixing sub-component can also be a hollow cylinder without a top surface and with external threads on the side surface, and the sealing sub-component 1223 can also be a sealing ring, a sealing paste, etc. Figure 5A

[0090] Further, the manufacturing process of the water nozzle 12 including only one bend is already relatively mature, and therefore, the water nozzle 12 can also be manufactured by combining two components each including only one bend. As shown in Figure 5B .

[0091] Figure 5B The structure of the water nozzle is shown in the figure. The figure actually shows one of the two components of the water nozzle 12 manufactured by the injection molding process. In the figure, the component is illustrated as including the first component 121 and part of the second component 122. After the different components of the water nozzle 12 are manufactured, they can be combined to obtain the complete water nozzle 12.

[0092] It should be noted that the figure is only a schematic diagram of the component. The second component included in the component can also have external threads at the opening position. The two components included in the water nozzle can be connected by various methods such as glue connection, heat connection, welding, threaded connection, etc. The specific shape of the component and how the two components are connected can be set as needed, and the present specification does not limit this.

[0093] Further, the water nozzle including two bends is described in detail above, but in the case where the third position is located on the side surface of the water cooling head away from the heat source, the shape of the water nozzle can be a cylinder.

[0094] Specifically, the heat exchange module 1 includes a water cooling head 11 and a water nozzle 12. The third position at which the water cooling head 11 and the water nozzle 12 are connected is located on the side surface of the water cooling head 11 close to the area of the heat exchange module 1, and the distance between the third position and the lower bottom surface of the heat exchange module 1 is greater than a preset first distance threshold. As shown in Figure 6A and Figure 6B .

[0095] Figure 6A ​As shown in the structural schematic diagram of the heat exchange module provided in the specification, the water cooling head 11 in the diagram is a cuboid structure, and the lower bottom surface of the water cooling head 11 is in contact with the heat source. The contact position of the water cooling head 11 and the water nozzle 12 is on the side surface of the water cooling head 11 closest to the heat dissipation component, and the water cooling head 11 is located at the upper section of the side surface, that is, the distance between the water cooling head 11 and the lower bottom surface of the heat exchange module 1 is greater than the preset first distance threshold.

[0096] In the specification, the lower bottom surface of the heat exchange module 1 is the lower bottom surface of the smallest cuboid containing the heat exchange module 1. In the example shown in FIG. 6, the lower bottom surface of the heat exchange module 1 can be coplanar with the lower bottom surface of the water cooling head 11.

[0097] Figure 6B As shown in the structural schematic diagram of the water nozzle provided in the specification, the shape of the water nozzle 12 can be a cylinder, one end of which is in contact with the connection module 2 at the first position, and the other end is in contact with the water cooling head 11 at the third position.

[0098] It should be noted that the shapes of the connection parts of the water nozzle 12 and the water cooling head 11, and the shapes of the connection parts of the water cooling and the water pipe are only examples, and the specific shapes of the connection parts of the water nozzle 12 and the water cooling head 11, and the specific shapes of the connection parts of the water cooling and the water pipe can be set as needed, and the specification does not limit this.

[0099] In addition, in the specification, the heat dissipation module 3 of the water cooling radiator can be a water cooling row 31. Therefore, the water cooling row 31 can be a cuboid structure, and when it is installed in the case, the common installation position is the top of the case, that is, the bottom surface of the water cooling row 31 is parallel to the top surface of the case.

[0100] The water cooling row 31 is provided with an inlet and outlet water port 32, that is, an inlet water port and an outlet water port, wherein the inlet water port and the outlet water port are adjacent. Figure 7

[0101] Figure 7 As shown in the structural schematic diagram of the heat dissipation module provided in the specification, the heat dissipation module 3 is taken as an example of the water cooling row 31, and it can be seen that the water cooling row 31 is provided with an inlet water port and an outlet water port, and the inlet water port and the outlet water port are adjacent. The inlet and outlet water port 32 is arranged on the long side of the water cooling row 31.

[0102] Taking the water cooling row 31 as an example, when the water cooling row 31 is arranged on the top of the case, the lower bottom surface of the water cooling row 31 is in contact with the top surface of the case, and the upper top surface of the water cooling row 31 faces the heat exchange component. The connection module 2 is connected to the heat dissipation module 3 at the position of the inlet and outlet water port 32, and obviously, the second position is located on the outer surface of the heat dissipation module 3 close to the heat exchange module 1. ​

[0103] Further, the positions of the corresponding CPUs in different types of cases are not completely the same. Taking the central part of the mainboard as the reference, there are cases where the CPU is on the left or right side of the reference position. Figure 7 For example, if the inlet and outlet 32 is arranged at the left segment of the long side, there may be a case where the CPU is on the right side of the reference position. In this case, the distance between the first position and the second position will be relatively far, and the length required for the connection module 2 will be relatively long.

[0104] In the case where the connection module 2 always needs to be deployed in the case and there is a certain distance between the connection position of the connection module 2 and the heat exchange module 1 and the vertical distance from the mainboard, the longer the length of the connection module 2, the larger the space occupied in the case, and the greater the probability of unattractive wiring in the case. Therefore, in general, when deploying a water-cooled radiator in a heat dissipation case, a shorter connection module 2 is usually selected. Based on the above idea, the water-cooled radiator in the present specification can be provided with a water-cooled row 31 with the inlet and outlet 32 arranged at different positions.

[0105] Specifically, for example, there are three positions of the inlet and outlet 32 of the water-cooled row 31, and the long side of the water-cooled row 31 can be divided into three regions of left segment, middle segment and right segment according to the length of the long side of the water-cooled row 31.

[0106] Then, during the manufacture of each water-cooled row 31, the inlet and outlet 32 of the water-cooled row 31 are arranged in the corresponding regions of the left segment, middle segment and right segment according to random probability. It should be noted that only one pair of inlet and outlet 32 is arranged on one water-cooled row 31.

[0107] Finally, a selection request from the user can be responded to. The selection request is sent by the user according to the position of the CPU in the case. According to the selection request, the position of the CPU in the case can be determined, and if the position is in the middle segment, the water-cooled row 31 matched with the case can be determined as the case with the inlet and outlet 32 in the middle segment. The same applies to the left segment and the right segment.

[0108] Therefore, based on the above situation, the water-cooled radiator matched with the case can be deployed in the case of the user, which takes into account safety and practicality, and the deployed case is also more beautiful.

[0109] Of course, the above-mentioned heat dissipation module 3 is only an example of a water-cooled row, and the heat dissipation module 3 can also be a water-cooled plate, a water-cooled tower or other devices for cooling cold liquid.

[0110] Further, in the case of the heat dissipation module 3 being a water cooling radiator 31, the water inlet and outlet of the water cooling radiator 31 can also be located on the short side of the water cooling radiator.

[0111] Specifically, the heat dissipation module 3 can include a water cooling radiator 31. The water inlet and outlet 32 of the water cooling radiator 31 are adjacently arranged, and the water inlet and outlet 32 are arranged on the short side of the cooling radiator, and the water inlet and outlet 32 are arranged on the short side close to the heat source. Or, in the area close to the mainboard on the short side. If the lower bottom of the water cooling head faces the top in the forward direction, the position of the water inlet and outlet is located at the rear side of the water cooling radiator.

[0112] The connection module 2 can also include a second water pipe 22, wherein the first water pipe 21 is used to connect the water nozzle 12 and is connected to the second water pipe 22 at the second position, and the second water pipe 22 is used to connect the first water pipe 21 at the second position and is connected to the water inlet and outlet 32 of the water cooling radiator. As shown. Figure 8

[0113] Figure 8 The structure diagram of the water cooling radiator provided in the present specification. The water cooling radiator includes a heat exchange module 1, a connection module 2 and a heat dissipation module 3, the connection module includes a first water pipe 21 and a second water pipe 22, the heat dissipation module 3 includes a water cooling radiator 31 and a water inlet and outlet 32, the water inlet and outlet 32 are arranged on the short side of the water cooling radiator 31, and the specific position is located on the short side close to the heat source.

[0114] Figure 8 The water pipe contained in the dashed box in the middle is the second water pipe 22, one end of which is connected to the water inlet and outlet 32 of the water cooling radiator 31, and the other end is connected to the first water pipe 21 at the second position. The water pipe outside the dashed box is the first water pipe 21, one end of which is connected to the heat exchange module 1, and the other end is connected to the second water pipe 22 at the second position.

[0115] The second position is on the heat dissipation module 3, and the heat dissipation module 3 is the smallest cuboid containing the water cooling radiator 31.

[0116] Based on the same concept, the present specification also provides a heat dissipation case, wherein the heat dissipation case includes a case body and a water cooling radiator. Specifically, refer to the structure diagram shown in the above Figure 9

[0117] Figure 9 The structure diagram of the heat dissipation case provided in the present specification can be seen that the heat dissipation case includes a case body and a water cooling radiator, wherein the water cooling radiator includes a heat exchange module 1, a connection module 2 and a heat dissipation module 3, the heat dissipation module 3 is arranged on the top surface of the case, the heat exchange module 1 is arranged inside the case, specifically arranged on the electronic components inside the case, and the connection module 2 connects the heat exchange module 1 and the heat dissipation module 3.​​

[0118] It should be noted that the heat dissipation module 3 is arranged on the top surface of the case in the present specification only as an example, and in fact, the heat dissipation module 3 can be arranged on any one side surface of the case, and the positional relationship between the heat exchange module 1 arranged on the electronic component and the heat dissipation module 3 is the same as the above-mentioned positional relationship.

[0119] In addition, the water-cooled heat sink in the heat dissipation case can refer to the specific description of the water-cooled heat sink mentioned above, and the present specification will not be repeated here.

[0120] Each of the embodiments in the present specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment mainly explains the difference from other embodiments.

[0121] The above only describes the embodiments of the present specification and is not used to limit the present specification. The present specification can have various changes and variations for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present specification shall be included in the scope of claims of the present specification.
