[0048] The embodiments of the present application disclose a liquid cooling box, a liquid cooling module and a liquid cooling system to reduce space occupancy and ensure work efficiency.

[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] The liquid cooling box and liquid cooling module provided in the present application are suitable for liquid cooling systems. It can be understood that the liquid cooling system is used for temperature control, which can specifically cool and heat as needed. The heating principle is similar to the cooling principle, and both use thermodynamic principles to exchange heat. Exemplarily, the liquid cooling system includes a first heat exchanger, a compressor, a condenser, a liquid pump, a valve, a second heat exchanger and a heater. The liquid pump drives the liquid to circulate between the first heat exchanger and the load. The second heat exchanger is connected in parallel with the first heat exchanger through a valve. The liquid pump can also be used to drive the liquid to circulate between the second heat exchanger and the load. The first heat exchanger is used to realize the heat exchange between the liquid from the load and the medium at the condenser end, and the heater is connected in series or in parallel with the first heat exchanger to heat the liquid flowing through. Specifically, the high-temperature liquid heated by the heater can be used to heat the load end. When the liquid cooling system is used to cool the load end, the temperature of the liquid sent to the load end can also be accurately controlled by heating the liquid by the heater combined with cooling the liquid by the first heat exchanger and / or the second heat exchanger. It should be noted that the liquid in the system can be pure water or a refrigerant can be added.

[0051] In one specific example, see Figure 1, the heater 3 is connected in parallel with the first heat exchanger 4. The outlet of the load end is connected to the inlet of the liquid pump 2. The first heat exchanger 4 has a first channel and a second channel. Heat exchange is achieved between the first channel and the second channel. The outlet of the liquid pump 2 is connected to the inlet of the first channel. The outlet of the first channel is connected to the inlet of the load end. A condenser 82 and a compressor 81 are connected between the inlet and the outlet of the second channel. The first heat exchanger 4 can be specifically a plate exchanger. The outlet of the liquid pump 2 is also connected to the inlet of the second heat exchanger 6 through a valve 5. The outlet of the second heat exchanger 6 is connected to the inlet of the load end. The second heat exchanger 6 can be specifically a dry cooler to cool the liquid at the outlet of the load end. The outlet of the liquid pump 2 is also connected to the inlet of the heater 3. The outlet of the heater 3 is connected to the inlet of the load end. The heater 3 is used to heat the liquid at the outlet of the load end. In the liquid cooling system, the heater 3, the first heat exchanger 4 and the second heat exchanger 6 are connected in parallel. According to the system operation conditions, the outlet of the liquid pump 2 can be selectively connected to one of the heater 3, the first heat exchanger 4 or the second heat exchanger 6 through the corresponding valves controlling each device, or can be connected to different devices respectively and the flow rate connected to the corresponding device can be adjusted.

[0052] In another specific example, the heater 3 is connected in series with the first heat exchanger 4. Specifically, the heater 3 is connected between the outlet of the liquid pump 2 and the inlet of the first heat exchanger 4, or between the outlet of the first heat exchanger 4 and the inlet of the load end. The connection relationship of other components is the same as the above-mentioned parallel connection of the heater 3 and the first heat exchanger 4, which will not be repeated here.

[0053] In order to simplify the structure of the above-mentioned liquid cooling system, facilitate on-site assembly, reduce space occupancy, and ensure work efficiency, the present application provides a liquid cooling module, a liquid cooling box, and a liquid cooling system, which can compactly arrange at least part of the components in the above-mentioned liquid cooling system and insulate the high-temperature area and the low-temperature area in the system, thereby reducing the size of the module and the system while ensuring work efficiency.

[0054] In some embodiments, see Figure 2-Figure 7 The liquid cooling module provided in the present application includes a shell 1, a pump body and at least one of a heater 3, a first heat exchanger 4, and a valve 5. Among them, a liquid inlet chamber 11 and a liquid outlet chamber 12 are formed in the shell 1. The shell 1 is the main integrated structure of the liquid cooling module, which is used to centrally arrange devices such as the liquid pump 2. It can be understood that the shell 1 can be an integral structure or a split structure connected by a conventional sealing method. In one example, the shell 1 is an integral structure, that is, it has excellent sealing performance through integral molding. In another example, the shell 1 is a split structure, including a base and a shell cover, and the base and the shell cover are sealed. The shape and size of the liquid inlet chamber and the liquid outlet chamber are not specifically limited in this embodiment and can be set as needed.

[0055] A heat insulating portion 13 is formed between the liquid inlet cavity 11 and the liquid outlet cavity 12. The liquid inlet cavity 11 and the liquid outlet cavity 12 are arranged adjacent to each other. The heat insulating portion 13 is arranged between the liquid inlet cavity 11 and the liquid outlet cavity 12 to disconnect the thermal bridge therebetween. It can be understood that the heat insulating portion 13 can be a part of the shell 1, such as the part of the wall of the shell 1 separating the liquid inlet cavity 11 and the liquid outlet cavity 12 is made of heat insulating material and used as the heat insulating portion 13, or the heat insulating portion 13 can be a heat insulating cavity formed by the shell 1, etc. The thermal conductivity of the heat insulating portion 13 is lower than the thermal conductivity of the shell 1 itself, that is, compared with the shell 1, it has a heat insulating effect.

[0056] At least one of the heater 3, the first heat exchanger 4, and the valve 5 is connected between the liquid inlet chamber 11 and the liquid outlet chamber 12, wherein the valve 5 is used to connect with the second heat exchanger 6 to adjust the connection between the liquid inlet chamber 11 and the second heat exchanger 6. The liquid pump 2 is arranged in the housing 1, the outlet of the liquid pump 2 is connected to the liquid inlet chamber 11, and the inlet of the liquid pump 2 is used to connect with the load end. The liquid pump 2 is used to pump the liquid at the load end through the liquid inlet chamber 11 to the heater 3, the first heat exchanger 4 or the valve 5, and then return to the liquid outlet chamber 12 and be discharged from the liquid outlet chamber 12. Specifically, the liquid pump 2, the heater 3, the first heat exchanger 4 and the valve 5 can be connected to the housing 1 to form the above-mentioned connection relationship. In the present application, at least one of the heater 3, the first heat exchanger 4 and the valve 5 is integrated with the liquid pump 2 in the liquid cooling module, and when the liquid cooling system is assembled on site, there is no need to assemble the corresponding components.

[0057] The liquid cooling module and liquid cooling box provided by the present application are applied, by setting a shell 1, the shell 1 is formed with a liquid inlet chamber 11 and a liquid outlet chamber 12, the liquid pump 2 can be arranged in the shell 1, and at least one of the heater 3, the first heat exchanger 4 and the valve 5 can be arranged between the liquid inlet chamber 11 and the liquid outlet chamber 12. The liquid pump 2 can pump the liquid at the load end to the liquid inlet chamber 11, and enter the corresponding heater 3, the first heat exchanger 4 or the valve 5 and the second heat exchanger 6 connected to the valve 5 through the liquid inlet chamber 11. The liquid heated by the heater 3, cooled by the first heat exchanger 4 or cooled by the second heat exchanger 6 flows back to the liquid outlet chamber 12, and flows back to the load end from the liquid outlet chamber 12, completing a cycle.

[0058] In summary, the liquid cooling module and liquid cooling box provided by the present application integrate at least some components such as the liquid pump 2 and the heater 3, the first heat exchanger 4, and the valve 5 through the housing 1, and the structure is compact, reducing the overall space occupation. At the same time, by arranging a heat insulating portion 13 between the liquid inlet cavity 11 and the liquid outlet cavity 12 to isolate most of the thermal bridges between the liquid inlet cavity 11 and the liquid outlet cavity 12, the heat transfer of the liquid in the liquid inlet cavity 11 and the liquid outlet cavity 12 is significantly reduced, and energy waste is avoided, thereby improving the working efficiency of the liquid cooling system.

[0059] In some embodiments, the heat insulating portion 13 includes a heat insulating material layer disposed on a partitioning side wall 14 of the shell 1 between the liquid inlet cavity 11 and the liquid outlet cavity 12. Exemplarily, the shell 1 includes an outer shell and a partitioning side wall 14 disposed in the outer shell, and the partitioning side wall 14 divides the cavity surrounded by the outer shell into a liquid inlet cavity 11 and a liquid outlet cavity 12, and a heat insulating material layer is disposed on the partitioning side wall 14 to isolate the heat exchange between the liquid inlet cavity 11 and the liquid outlet cavity 12 on both sides of the partitioning side wall 14. It can be understood that the heat insulating material layer can be a heat insulating coating coated on the surface of the partitioning side wall 14, or can be an interlayer embedded between the partitioning side walls 14, or the partitioning side wall 14 can be made of heat insulating material as a whole to form a heat insulating material layer. Of course, a heat insulating material layer can also be disposed on the entire surface of the shell 1, but the cost is relatively high.

[0060] In some embodiments, the heat insulating portion 13 includes a cavity provided on a partition side wall 14 of the shell 1 between the liquid inlet cavity 11 and the liquid outlet cavity 12. In the above-mentioned embodiment, the heat insulating portion 13 adopts a heat insulating material layer. The difference between this embodiment and the above-mentioned embodiment is that the heat insulating portion 13 adopts a cavity formed by the shell 1. It can be understood that the cavity can be either a closed cavity or an open cavity with an opening. In addition, when the cavity is a closed cavity, the cavity can be filled with air or other heat insulating materials, or it can be a vacuum cavity. When the cavity is an open cavity, it can be filled with air or other heat insulating materials. The cavity is used to disconnect the thermal bridge between the liquid inlet cavity 11 and the liquid outlet cavity 12, without the need to provide a heat insulating material layer, thereby reducing the material cost, and the heat insulation effect is stable and reliable.

[0061] In some embodiments, multiple cavities are provided at intervals on the partition side wall 14. On the one hand, by providing multiple cavities, the area of ​​the cavity occupied by the partition side wall 14 is increased, thereby improving the heat insulation effect. On the other hand, the multiple cavities are provided at intervals, and the intervals can ensure the structural strength of the housing 1 and improve the reliability of the overall liquid cooling module. Figure 4 In the left and right directions shown in FIG. 1 , the separated liquid inlet chamber 11 and liquid outlet chamber 12 are distributed vertically, and the multiple cavities are arranged along Figure 4 The left and right directions are shown in sequence.

[0062] In some embodiments, one end of the cavity extends to the edge of the shell 1. In this embodiment, the cavity is an open cavity, one end of which is open, and the other end can be either closed or open. As set above, the cavity can be prepared by machining grooves on the partition side wall 14, which is convenient for cavity molding and reduces the preparation cost of the liquid cooling module. It can be understood that the cavity extending to the edge of the shell 1 refers to a position that is not connected to the liquid inlet cavity 11 or the liquid outlet cavity 12. Exemplary, Figure 4 The hollow cavity extends to the edge of the housing 1 in a direction perpendicular to the paper surface.

[0063] In some embodiments, the housing 1 includes a base 15, a first shell cover 16 and a second shell cover 17. The base 15 is provided with a liquid inlet groove 151 and a liquid outlet groove 152, and a heat insulation portion 13 is provided between the liquid inlet groove 151 and the liquid outlet groove 152; the first shell cover 16 is provided on the base 15, and forms a liquid inlet cavity 11 with the liquid inlet groove 151; the second shell cover 17 is provided on the base 15, and forms a liquid outlet cavity 12 with the liquid outlet groove 152, and the first shell cover 16 and the second shell cover 17 are arranged at intervals. In this embodiment, the housing 1 adopts a split structure for easy molding. By providing a liquid inlet groove 151 and a liquid outlet groove 152 on the base 15, a cavity for accommodating liquid is formed, and the side wall between the liquid inlet groove 151 and the liquid outlet groove 152 is a partition side wall 14, and the heat insulation portion 13 can be provided on the partition side wall 14. The first shell cover 16 is sealed and connected to the edges of the liquid inlet groove 151, thereby forming a liquid inlet cavity 11; the second shell cover 17 is sealed and connected to the edges of the liquid outlet groove 152, thereby forming a liquid outlet cavity 12. The first shell cover 16 and the second shell cover 17 are arranged at intervals, and the specific interval position is opposite to the partition side wall 14. On the one hand, the liquid inlet groove 151 and the liquid outlet groove 152 are thermally insulated by the setting of the insulation part 13, and at the same time, the first shell cover 16 and the second shell cover 17 are also thermally insulated by the setting of the interval, thereby ensuring reliable thermal insulation between the liquid inlet cavity 11 and the liquid outlet cavity 12. The above arrangement further improves the thermal insulation effect, and the structure is stable and reliable, and easy to assemble.

[0064] In some embodiments, the extension direction of the interval between the first shell cover 16 and the second shell cover 17 is consistent with the extension direction of the heat insulation part 13, and the interval is arranged opposite to the heat insulation part 13, and the width of the interval is not less than the width of the heat insulation part 13. Figure 4 In the paper direction, the projection of the interval coincides with the projection of the heat insulating portion 13. Exemplarily, the projection of the heat insulating portion 13 falls within the range of the interval projection. The width of the interval is not less than the width of the heat insulating portion 13, which prevents the heat of the first shell cover 16 from exchanging heat with the liquid outlet cavity 12, and the heat of the second shell cover 17 from exchanging heat with the liquid inlet cavity 11, further improving the heat insulation effect.

[0065] In some embodiments, the liquid inlet cavity 11 is provided with at least one of a first liquid inlet outlet 112a, a second liquid inlet outlet 112b, and a third liquid inlet outlet 112c, and the liquid outlet cavity 12 is correspondingly provided with at least one of a first liquid outlet inlet 121a, a second liquid outlet inlet 121b, and a third liquid outlet inlet 121c; the first liquid inlet outlet 112a is used to set the inlet of the heater 3, and the first liquid outlet inlet 121a is used to set the outlet of the heater 3; the second liquid inlet outlet 112b is used to set the inlet of the first heat exchanger 4, and the second liquid outlet inlet 121b is used to set the outlet of the first heat exchanger 4; the third liquid inlet outlet 112c is used to connect to the inlet of the second heat exchanger 6, and the third liquid outlet inlet 121c is used to connect to the outlet of the second heat exchanger 6, and the valve 5 is used to adjust the connection between the third liquid inlet outlet 112c and the second heat exchanger 6. The liquid outlet cavity 12 is provided with a module outlet 122 to connect to the load end. That is, by setting interfaces corresponding to each device on the liquid inlet cavity 11 and the liquid outlet cavity 12, each device is directly connected to the housing 1 without using a pipeline, so that the overall structure of the liquid cooling module is more compact and occupies less space. Compared with the pipeline connection, the two ends of the pipeline need to be connected separately to generate two interfaces, while the device is directly connected to the housing 1 only needs one interface, which reduces the leakage points, improves the reliability of the liquid cooling module, simplifies the assembly process, and reduces the overall material cost and assembly cost.

[0066] Exemplarily, the liquid inlet cavity 11 is provided with a first liquid inlet outlet 112a, a second liquid inlet outlet 112b and a third liquid inlet outlet 112c, and the liquid outlet cavity 12 is correspondingly provided with a first liquid outlet inlet 121a, a second liquid outlet inlet 121b and a third liquid outlet inlet 121c. The liquid cooling module comprises a heater 3, a first heat exchanger 4 and a valve 5. Among them, the inlet of the heater 3 is provided at the first liquid inlet outlet 112a, and the outlet of the heater 3 is provided at the first liquid outlet inlet 121a; the inlet of the first heat exchanger 4 is provided at the second liquid inlet outlet 112b, and the outlet of the first heat exchanger 4 is provided at the second liquid outlet inlet 121b; the valve 5 is provided in the liquid inlet cavity 11, the third liquid inlet outlet 112c is used to connect with the inlet of the second heat exchanger 6, the third liquid outlet inlet 121c is used to connect with the outlet of the second heat exchanger 6, and the valve 5 is used to adjust the connection between the third liquid inlet outlet 112c and the second heat exchanger 6. In this embodiment, the first heat exchanger 4, the heater 3 and the valve 5 controlling the second heat exchanger 6 are integrated into the housing 1, and the first heat exchanger 4 is connected in parallel with the heater 3, which has a higher degree of integration. In some specific examples, the second liquid outlet inlet 121b can also be connected to the liquid injection and discharge pipe.

[0067] In order to control the flow rate of the liquid inlet chamber 11 entering the heater 3, the heater 3 includes a heater body and a valve connected to the heater body, such as a switch valve or a flow valve, that is, the heater body and the valve for controlling its flow rate are integrated into the housing 1. The valve can control the flow rate of the liquid in the liquid inlet chamber 11 that flows through the heater body and flows into the liquid outlet chamber 12, thereby achieving precise adjustment of the outlet liquid temperature. Exemplarily, a flow valve is provided between the outlet of the heater body and the liquid outlet chamber 12, or a flow valve is provided between the inlet of the heater body and the liquid inlet chamber 11, and the flow valve is used to adjust the flow rate of the liquid flowing from the liquid inlet chamber 11 through the heater body into the liquid outlet chamber 12, so that the liquid in the liquid inlet chamber 11 partially enters the heater body and partially enters the first heat exchanger 4 according to a suitable ratio, thereby achieving precise adjustment of the outlet liquid temperature, or the liquid in the liquid inlet chamber 11 does not flow into the heater body but all enters the first heat exchanger 4. In another example, a switch valve may be provided between the outlet of the heater body and the liquid outlet chamber 12, or between the inlet of the heater body and the liquid inlet chamber 11, and the switch valve may control the connection between the heater body and the liquid inlet chamber 11 or the liquid outlet chamber 12. It is understandable that, without providing the valve for controlling the flow of the heater body, the outlet temperature of the first heat exchanger 4 may be adjusted so that the temperature of the liquid flowing into the liquid outlet chamber 12 meets the requirements.

[0071] The above embodiments illustrate the case where the heater 3 is connected in parallel with the first heat exchanger 4. In other embodiments, the heater 3 and the first heat exchanger 4 may also be connected in series. The liquid inlet chamber 11 is provided with a first liquid inlet outlet 112a and a second liquid inlet outlet 112b, and the liquid outlet chamber 12 is correspondingly provided with a first liquid outlet inlet 121a and a second liquid outlet inlet 121b; the first liquid inlet outlet 112a is used to set the inlet of one of the heater 3 and the first heat exchanger 4, and its outlet is used to connect with the inlet of the other, and the first liquid outlet inlet 121a is used to set the outlet of the other; the second liquid inlet outlet 112b is used to connect with the inlet of the second heat exchanger 6, and the second liquid outlet inlet 121b is used to connect with the outlet of the second heat exchanger 6, and the valve 5 is used to adjust the connection between the second liquid inlet outlet 112b and the second heat exchanger 6.

In this embodiment, the first liquid inlet chamber 11a is provided at the inlet of the liquid pump 2, and the module inlet 131 can be specifically connected to the load end through a pipeline or the like. Under the action of the liquid pump 2, the liquid from the load end enters the first liquid inlet chamber 11a through the module inlet 131, and then enters the liquid pump 2 through the liquid pump chamber outlet 132. When the liquid pump 2 is connected to the system through a pipeline, the flow resistance is relatively large. In this embodiment, a first liquid inlet cavity 11a is provided in front of the inlet of the liquid pump 2. For example, the flow area of ​​the first liquid inlet cavity 11a is larger than the flow area of ​​the connecting pipeline, which significantly reduces the flow resistance compared to the connection between the pipeline and the liquid pump 2, thereby solving the problem of large flow resistance of the liquid pump 2 in the prior art. The shape of the liquid pump cavity can be set as needed, and is not specifically limited here. When the volume of the liquid pump cavity is small, it is not easy to generate bubbles therein to prevent bubbles from entering the liquid pump 2.

The specific direction of the connecting channel 11c, that is, the extension direction, can be set as needed, and is not specifically limited here.
