In addition, the cold plate type liquid cooling radiator is easy to maintain and the cost is remarkably reduced. Example embodiments of the present disclosure will be described below with reference to fig. 1 to 10.

Fig. 1 and 2 show schematic structural views of a cold plate type liquid-cooled radiator according to an embodiment of the present disclosure, wherein fig. 1 shows an assembled state thereof and fig. 2 shows an exploded state thereof. Fig. 3 shows a schematic cross-sectional view of the cold plate liquid-cooled radiator shown in fig. 1 along section line A-A. As shown in fig. 1-3, the cold plate liquid-cooled radiator described herein includes a base plate 10, a cover plate 20, a seal ring 30, and a fastener 40.

As shown in fig. 1-3, a first side of the base plate 10 is used to contact an electronic device (not shown) to be cooled, such as a CPU, GPU, or other type of electronic device. A second side of the base plate 10 opposite to the first side thereof is provided with heat radiating fins 11. In one embodiment, the base plate 10 and the heat radiating fins 11 provided thereon may be made of a metal material to provide high thermal conductivity. It should be appreciated that the base plate 10 and the heat dissipating fins 11 disposed thereon may also be made of any other suitable material, as embodiments of the present disclosure are not limited in this regard.

In embodiments of the present disclosure, the bottom plate 10 extends in a generally horizontal direction, depending on the orientation of the cold plate liquid cooled radiator shown in fig. 1-3, a first side of the bottom plate 10 may also be referred to as a bottom or underside of the bottom plate 10, and a second side of the bottom plate 10 may also be referred to as a top or underside of the bottom plate 10. It should be appreciated that the first and second sides of the base plate 10 may also be oriented in other directions with the cold plate liquid cooled radiator in other orientations, as embodiments of the present disclosure are not limited in this respect.

Fig. 4 and 5 show the structure of the base plate 10 more clearly, wherein fig. 4 shows a first side of the base plate 10 and fig. 5 shows a second side of the base plate 10. As shown in fig. 4, the first side of the base plate 10 comprises a heat dissipation area 15 for contacting the electronic device to be cooled, thereby removing heat from the electronic device. As shown in fig. 1-5, the base plate 10 may be connected to the electronic device to be cooled by screws or other types of connectors 14, thereby connecting the cold plate liquid-cooled heat sink to the electronic device. As shown in fig. 5, the heat radiating fins 11 are provided at positions on the second side of the bottom plate 10 that substantially correspond to the heat radiating areas 15 to efficiently conduct heat from the electronic device to the cooling liquid.

With continued reference to fig. 1-3, the first side of the cover plate 20 faces the second side of the base plate 10. The first side of the cover plate 20 is recessed to form an inner space 90 for accommodating the heat radiating fins 11 together with the second side of the bottom plate 10. A second side of the cover plate 20 opposite to its first side is used to connect coolant lines (not shown). With this arrangement, the cooling fluid provided by the external heat sink (e.g., an outdoor cooling tower, not shown) may flow into the interior space 90 via the inlet pipe in the coolant line and return to the external heat sink via the return pipe in the coolant line, thereby effecting cooling of the electronic equipment in contact with the first side of the base plate 10. The coolant lines may be implemented using hoses or any other type of conduit, as embodiments of the present disclosure are not limited in this regard.

In one embodiment, the cover plate 20 may be made of a polymer material through a molding process to improve the production efficiency of the heat sink and reduce the overall cost of the heat sink. It should be appreciated that the cover plate 20 may also be made of any other suitable material or by any other suitable process, as embodiments of the present disclosure are not limited in this regard.

In embodiments of the present disclosure, the cover plate 20 extends in a generally horizontal direction, depending on the orientation of the cold plate liquid cooled radiator shown in fig. 1-3, a first side of the cover plate 20 may also be referred to as a bottom or underside of the cover plate 20, and a second side of the cover plate 20 may also be referred to as a top or underside of the cover plate 20. It should be appreciated that the first and second sides of the cover plate 20 may also face in other directions with the cold plate liquid cooled radiator in other orientations, as embodiments of the present disclosure are not limited in this respect.

Fig. 6 and 7 more clearly show the structure of the cover plate 20, wherein fig. 6 shows a first side of the cover plate 20 and fig. 7 shows a second side of the cover plate 20. Referring to fig. 3 and 6, the central region 26 of the first side of the cover plate 20 is recessed with respect to the peripheral portion of the first side of the cover plate 20, thereby forming an inner space 90 for accommodating the heat radiating fins 11 together with the second side of the bottom plate 10. Referring to fig. 1 to 3 and 7, two adaptor connection parts 22 are provided on the second side of the cover plate 20, one adaptor connection part 22 being used to connect a feed pipe in a coolant line through the adaptor 50, and the other adaptor connection part 22 being used to connect a return pipe in the coolant line through the adaptor 50. The two adapter connection parts 22 communicate with the inner space 90, so that it is possible to supply the cooling liquid received via the liquid inlet pipe and the corresponding adapter 50 to the inner space 90 and return the warmed cooling liquid to the external cooling source via the corresponding adapter 50 and the liquid return pipe.

Referring to fig. 1 to 3 and 7, the adapter connection portion 22 protrudes from the second side of the cover plate 20 and includes internal threads. Accordingly, adapter 50 includes external threads that mate with internal threads on adapter coupling portion 22. In this way, the adapter 50 can be screwed onto the adapter connection 22. In order to improve the sealing performance between the adapter 50 and the adapter connection 22, a seal 60 may be provided between the adapter 50 and the adapter connection 22 for preventing leakage of the coolant from the gap between the adapter 50 and the adapter connection 22.

The seal 60 may be disposed at any suitable location between the adapter 50 and the adapter connector 22. In one embodiment, as shown in fig. 3 and 7, the bottom of the adapter connection 22 is provided with a step 221 for supporting the seal 60. In this case, the seal 60 may be pressed by both the end of the adapter 50 and the step 221, thereby achieving a seal between the adapter 50 and the adapter connection 22. In other embodiments, the seal 60 may be provided at other locations, as embodiments of the present disclosure are not limited in this regard. For example, a seal 60 may be provided between the top of the adapter connector 22 and the adapter 50, also enabling sealing between the adapter 50 and the adapter connector 22.

In one embodiment, as shown in fig. 1 and 7, a sump 23 is provided on the second side of the cover plate 20, and the adapter connection 22 is located in the sump 23. With this arrangement, even in the event that the coolant accidentally leaks from the gap between the adapter 50 and the adapter connecting portion 22, the liquid collecting tank 23 can collect the coolant, thereby preventing the coolant from flowing onto the electronic apparatus to some extent, avoiding damage to the electronic apparatus.

Referring to fig. 3 and 7, the adapter connector 22 is integrally formed on the cover plate 20. For example, in the case where the cover plate 20 is made of a high polymer material, the adapter connector 22 may be integrally formed on the cover plate 20, for example, during a molding process of the cover plate 20. In addition, the adaptor 50 can also be made of polymer material to reduce the overall cost of the radiator.

It should be understood that the above description with respect to the adapter connection 22 is merely an example and is not intended to limit embodiments of the present disclosure in any way. For example, a further plurality of adapter connections 22 may be provided on the second side of the cover plate 20 for connecting additional inlet or return pipes via the respective adapter 50. Furthermore, the adapter connector 22 may be formed on the cover plate 20 in other ways, for example the adapter connector 22 may be embedded in the cover plate 20, as will be further described below in connection with fig. 8-10.

Referring to fig. 2, 3 and 6, the gasket 30 is disposed around the inner space 90 between the second side of the base plate 10 and the first side of the cover plate 20. In other words, the seal ring 30 is closed such that the interior space 90 is inside the seal ring 30. The sealing ring 30 is adapted to be pressed by the bottom plate 10 and the cover plate 20 with the cover plate 20 being connected to the bottom plate 10 for sealing a gap between the second side of the bottom plate 10 and the first side of the cover plate 20, thereby preventing leakage of the cooling liquid in the inner space 90 through the gap. The number of seal rings 30 may be one or more. When the number of the seal rings 30 is plural, the plurality of seal rings 30 are disposed in a nested manner, that is, the plurality of seal rings 30 are disposed in order from the inside to the outside with respect to the internal space 90. For example, in one embodiment, as shown in fig. 2, 3, and 6, the number of seal rings 30 is two, with one seal ring 30 being closer to the interior space 90 than the other seal ring 30, nested inside the other seal ring 30. In the case where the number of the seal rings 30 is plural, good sealing performance can be provided, and leakage of the cooling liquid through the gap between the second side of the bottom plate 10 and the first side of the cover plate 20 can be more reliably prevented. It should be appreciated that in some embodiments, the number of sealing rings 30 is one to meet the sealing performance requirements, in which case only one sealing ring 30 may be provided between the second side of the base plate 10 and the first side of the cover plate 20.

With continued reference to fig. 1-3, the fastener 40 is adapted to removably connect the cover plate 20 to the base plate 10. As shown in fig. 3, in the case where the cover plate 20 is coupled to the base plate 10 using the fastener 40, the gasket 30 will be pressed by the base plate 10 and the cover plate 20, thereby sealing the inner space 90, preventing the coolant in the inner space 90 from leaking through the gap between the base plate 10 and the cover plate 20.

In embodiments according to the present disclosure, the fasteners 40 may removably connect the cover plate 20 to the base plate 10 using any suitable connection technique. For example, in one embodiment, as shown in fig. 1-3, the fastener 40 includes a plurality of fastening screws 41. In order to achieve connection between the cover plate 20 and the base plate 10 using the fastening screws 41, the cover plate 20 may be provided with a plurality of screw fixing holes 25 through which the plurality of fastening screws 41 pass, as shown in fig. 2, 6 and 7. Accordingly, a plurality of screw holes 12 are provided on the base plate 10 at positions corresponding to the plurality of screw fixing holes 25, as shown in fig. 2, 4 and 5. In assembling the cold plate type liquid-cooled radiator, the plurality of screw fixing holes 25 on the cover plate 20 may be aligned with the plurality of screw holes 12 on the base plate 10, respectively, and then the respective fastening screws 41 may be screwed into the screw holes 12 through the corresponding screw fixing holes 25, thereby connecting the cover plate 20 to the base plate 10.

It should be understood that the above description with respect to fastener 40 is merely an example and is not intended to limit embodiments of the present disclosure in any way. Any presently known or later-developed fastening techniques may be used in connection with the embodiments of the present disclosure.

In some embodiments, as shown in fig. 3 to 6, in order to achieve accurate positioning between the cover plate 20 and the base plate 10, a first positioning piece 241 is provided on a first side of the cover plate 20, and a first positioning hole 13 into which the first positioning piece 241 is inserted is provided on the base plate 10. The first positioning member 241 may be provided at any suitable location on the first side of the cover plate 20 and may be of any suitable number. For example, as shown in fig. 6, the first positioning pieces 241 may be provided at opposite ends of the cover plate 20 in pairs. Further, the first positioning member 241 may be columnar or any other suitable shape. With this arrangement, alignment between the cover plate 20 and the base plate 10 can be conveniently achieved by having the first positioning pieces 241 inserted into the respective first positioning holes 13.

In some embodiments, as shown in fig. 1-3, the cold plate liquid-cooled radiator further includes a mounting bracket 70 disposed on the second side of the cover plate 20. The mounting bracket 70 may be generally square-shaped in sheet form to conform to the second side of the cover plate 20. The mounting bracket 70 includes a plurality of mounting holes (not shown) provided corresponding to the plurality of screw fixing holes 25, respectively. A plurality of fastening screws 41 may pass through the corresponding mounting holes, screw fixing holes 25, and screw holes 12, respectively, to connect the cover plate 20 to the base plate 10. By providing the mounting bracket 70, the stress balance between the cover plate 20 and the bottom plate 10 at different positions can be ensured, thereby further improving the sealing performance of the sealing ring 30.

In some embodiments, as shown in fig. 2, 3 and 7, in order to achieve accurate positioning between the mounting bracket 70 and the cover plate 20, the second side of the cover plate 20 is provided with a second positioning piece 242, and the mounting bracket 70 is provided with a second positioning hole 71 into which the second positioning piece 242 is inserted. The second positioning member 242 may be disposed at any suitable location on the second side of the cover plate 20 and may be of any suitable number. For example, as shown in fig. 7, the second positioning pieces 242 may be provided at opposite ends of the cover plate 20 in pairs. Further, the second positioning member 242 may be columnar or any other suitable shape. With this arrangement, alignment between the cover plate 20 and the mounting bracket 70 can be conveniently achieved by having the second positioning pieces 242 inserted into the respective second positioning holes 71.

In some embodiments, as shown in fig. 3 and 6, a clamping groove 21 for limiting the sealing ring 30 is provided on the first side of the cover plate 20. In the case of two sealing rings 30, two clamping grooves 21 are correspondingly provided on the first side of the cover plate 20. Each clamping groove 21 is also closed for limiting the corresponding sealing ring 30. In case the sealing rings 30 are of other numbers, a corresponding number of clamping grooves 21 may be provided on the first side of the cover plate 20 for limiting the corresponding sealing rings 30. With this arrangement, the seal ring 30 can be reliably held in the limit groove 21 while being pressed by the cover plate 20 and the base plate 10, preventing the seal ring 30 from sliding with respect to the cover plate 20 or the base plate 10, so that the sealing effect can be further improved.

In some embodiments, as shown in fig. 3 and 5, the heat dissipation fins 11 include a first set of fins 111 and a second set of fins 112 spaced apart from each other. Accordingly, the inner space 90 includes a first space 91 and a second space 92, the first set of fins 111 being disposed within the first space 91, and the second set of fins 112 being disposed within the second space 92. As shown in fig. 3 and 6, the first space 91 and the second space 92 are separated from each other by the spacer 81 and communicate with each other via the through hole 82. The spacer 81 may be integrally formed on the cover plate 20. The through holes 82 may be provided at any suitable position with respect to the spacers 81, for example, may be provided at the ends of the spacers 81. With this arrangement, the cooling liquid supplied from the external heat sink can flow into the space in direct communication with the liquid inlet pipe, of the first space 91 and the second space 92, then flow into the space in direct communication with the liquid return pipe, of the first space 91 and the second space 92, via the through hole 82, and then return to the external heat sink via the liquid return pipe. In this way, the first space 91 and the second space 92 can space the cooling liquid with a lower temperature from the cooling liquid with a higher temperature, so that the waste of cooling capacity is avoided, and the heat dissipation efficiency of the cold plate type liquid cooling radiator is further improved.

As described above, the adapter connector 22 may be formed on the cover plate 20 in other manners, for example, the adapter connector 22 may be embedded in the cover plate 20. This arrangement will now be described in connection with fig. 8 to 10. Fig. 8 illustrates a schematic cross-sectional view of a cold plate liquid-cooled radiator according to another embodiment of the present disclosure, fig. 9 and 10 illustrate a schematic structural view of a cover plate in the cold plate liquid-cooled radiator illustrated in fig. 8, wherein fig. 9 illustrates a first side of the cover plate and fig. 10 illustrates a second side of the cover plate. The cold plate type liquid-cooled radiator shown in fig. 8 to 10 has a similar structure to that described in connection with fig. 1 to 7, only the differences between the two will be described hereinafter, and the same parts will not be repeated.

As shown in fig. 8 to 10, the adapter connector 22 is embedded in the cover plate 20, rather than being integrally formed with the cover plate 20. For example, in the case where the cover plate 20 is generally made of a high polymer material, the adapter connection portion 22 may be made of a metal material, and the adapter connection portion 22 may be buried in the cover plate 20 during manufacturing of the cover plate 20 using a molding process. In the case where the adapter connecting portion 22 is made of a metal material, the adapter 50 may also be made of a metal material. It should be appreciated that the adapter connector 22 may be made of any suitable material, as embodiments of the present disclosure are not limited in this regard.
