[0043] 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 heating module. 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 heat exchange between the liquid from the load and the medium at the condenser end, and the heating module is connected in series with the first heat exchanger to heat the coolant flowing through. Specifically, the high-temperature liquid heated by the heating module can be used to heat the load end, that is, the heating module is used to realize the heating of the liquid cooling system; when the liquid cooling system is used to cool the load end, the heating module can also be used to heat the liquid in combination with the first heat exchanger and / or the second heat exchanger to cool the liquid to accurately control the temperature of the liquid sent to the load end. It should be noted that the liquid in the system can be pure water or can be added with refrigerant.

[0044] See also Figure 1 , Figure 1 The schematic diagram of the principle of the liquid cooling system of a specific embodiment of the present application. The outlet of the load end is connected to the inlet of the liquid pump 2, and the outlet of the liquid pump 2 is connected to the inlet of the heater 9. The first heat exchanger 4 has a first channel and a second channel, and heat exchange is realized between the first channel and the second channel. The outlet of the heater 9 is connected to the inlet of the first channel, and 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, and 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. In the liquid cooling system, the heater 9 and the first heat exchanger 4 are connected in series, and 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 first heat exchanger 4 or the second heat exchanger 6 through the corresponding valve 5 via the heater 9, or can be connected to the heater 9 and the second heat exchanger 6 respectively, and the flow rate connected to the corresponding device can be adjusted.

[0045] In order to simplify the structure of the above-mentioned liquid cooling system, facilitate on-site assembly, and reduce leakage points, the present application provides a liquid cooling box, a liquid cooling module, and a liquid cooling system, which can integrate the pipelines and devices including at least the liquid pump 2 in the above-mentioned liquid cooling system. The liquid cooling module can connect other devices together by providing an integrated liquid cooling box, and a plurality of interconnected cavities are provided inside the shell 1 to form a channel for liquid circulation. Each device can be connected to the corresponding position of the shell 1 through a joint without being connected separately through pipelines. The devices in this application include but are not limited to a heater 9, a first heat exchanger 4 (such as a plate heat exchanger), a valve 5, an expansion tank, a sensor, etc.

[0046] In some embodiments, see Figure 2-Figure 6 The liquid cooling module provided by the present invention includes a shell 1, a heating module 3 and a liquid pump 2. A heating chamber 11 is formed in the shell 1. 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 first shell 1 and a second shell 1, and the first shell 1 and the second shell 1 are sealed. The heating chamber 11 is provided with a heating chamber inlet 111 and a heating chamber first outlet 112a. The shape, size and position of the heating chamber 11 are not specifically limited in this embodiment and can be set as needed.

[0047] The first outlet 112a of the heating chamber is used to be connected to the inlet of the first heat exchanger 4 or the valve 5, and the valve 5 is used to be connected to the second heat exchanger 6 to adjust the connection between the first outlet 112a of the heating chamber and the second heat exchanger 6; the heating module 3 is arranged in the heating chamber 11 to heat the liquid in the heating chamber 11. When the valve 5 is opened, the liquid in the heating chamber 11 enters the valve 5 and enters the second heat exchanger 6 through the outlet of the valve 5. When the valve 5 is closed, the heating chamber 11 is disconnected from the second heat exchanger 6. When the system is used for heating, the valve 5 can be controlled to be closed, and the compressor 81 connected to the first heat exchanger 4 is not started, that is, the first heat exchanger 4 is not used to cool the liquid, then the liquid is heated in the heating chamber 11 by the heating module 3, and flows through the first heat exchanger 4 to flow to the load end. When the system is used for refrigeration, the heating module 3 may not be started, and the liquid enters the first heat exchanger 4 through the heating chamber 11 to be cooled, or passes through the second heat exchanger 6 to be cooled when the valve 5 is opened, and flows to the load end after cooling; or the heating module 3 may also be started, and the heating module 3 heats the liquid in combination with the first heat exchanger 4 and / or the second heat exchanger 6 to cool the liquid, so as to accurately control the temperature of the liquid sent to the load end.

[0048] The liquid pump 2 is disposed in the housing 1, the inlet of the liquid pump 2 is used to communicate with the load end, and the outlet of the liquid pump 2 is disposed at the heating chamber inlet 111. It should be noted that the liquid pump 2 is disposed at the heating chamber inlet 111 means that the liquid pump 2 is installed at the heating chamber inlet 111, but is not connected to the heating chamber inlet 111 through a pipeline.

[0049] The liquid cooling module provided by the present invention is applied, by setting a shell 1, the shell 1 forms a heating chamber 11, the liquid pump 2 is arranged in the shell 1, the heating module 3 is arranged in the heating chamber 11, and the heating chamber 11 is also provided with a first heating chamber outlet 112a to be connected with the first heat exchanger 4 or the valve 5. The liquid pump 2 can pump the liquid at the load end to the heating chamber 11, and enter the corresponding first heat exchanger 4 or valve 5 and the second heat exchanger 6 connected with the valve 5 through the heating chamber 11 to be heated by the heating module 3, or cooled by the first heat exchanger 4 or the second heat exchanger 6, and then the liquid flows back to the load end to complete a cycle.

[0050] In summary, the liquid cooling module provided in the present application integrates the liquid pump 2 and the heating module 3 through the shell 1, and can install devices such as the first heat exchanger 4 or the valve 5 on the shell 1 without using pipelines. When the liquid cooling system is assembled on site, there is no need to install the liquid pump 2 and the heating module 3 and the corresponding liquid inlet and outlet pipes, which reduces the number of components assembled on site of the liquid cooling system, simplifies the assembly process, reduces the overall material cost and assembly cost, and the module design structure is compact, reducing the overall space occupancy.

[0051] In addition, by providing a heating chamber inlet 111 and a first heating chamber outlet 112a in the heating chamber 11 to integrate the liquid pump 2 and the first heat exchanger 4, or integrating the liquid pump 2 with the valve 5, the heating module 3 can be placed in the heating chamber 11, that is, no external heater 9 is required, thereby reducing the overall volume of the liquid cooling module, thereby reducing the space occupied, and facilitating its use in environments with high space requirements such as vehicles.

[0052] In some embodiments, the heating chamber 11 is further provided with a second heating chamber outlet 112b, which is used to connect to the valve 5, and the first heating chamber outlet 112a is used to connect to the inlet of the first heat exchanger 4. The liquid output by the liquid pump 2 enters the heating chamber 11, and the liquid in the heating chamber 11 can enter the first heat exchanger 4 through the first heating chamber outlet 112a on the one hand, and can enter the second heat exchanger 6 through the valve 5 on the other hand. The liquid flows through the first heat exchanger 4 or the second heat exchanger 6 and then flows into the load end. In this embodiment, interfaces are reserved for the first heat exchanger 4 and the valve 5 on the housing 1, so that the first heat exchanger 4 and the valve 5 can be installed on the housing 1 respectively. There is only one leakage point between the first heat exchanger 4 and the housing, and there is only one leakage point between the valve 5 and the housing. Compared with the first heat exchanger 4 and the valve 5 being connected by pipelines, there is a leakage point at each end of the pipeline. Therefore, the above integrated setting reduces the number of leakage points and improves the reliability of the liquid cooling module.

[0053] In some embodiments, the liquid cooling module further includes a first heat exchanger 4 provided at the first outlet 112a of the heating chamber and a valve 5 provided at the second outlet 112b of the heating chamber. That is, the heating chamber 11 is provided with the first outlet 112a of the heating chamber and the second outlet 112b of the heating chamber, the inlet of the first heat exchanger 4 is provided at the first outlet 112a of the heating chamber, and is not connected by a pipeline, and the valve 5 is provided at the second outlet 112b of the heating chamber, and is not connected by a pipeline. The first heat exchanger 4 and the valve 5 are also integrated into the housing 1, which further reduces the number of components installed on site of the liquid cooling system, simplifies the assembly process, and reduces leakage points. In some specific examples, the valve 5 is a two-way valve, the inlet of the two-way valve is connected to the second outlet 112b of the heating chamber, and the outlet of the two-way valve is connected to the inlet of the second heat exchanger 6.

In some other specific examples, the valve 5 is a three-way valve, the inlet of the three-way valve is arranged in the heating chamber 11, and the two outlets of the three-way valve are respectively connected to the first outlet 112a and the second outlet 112b of the heating chamber.

[0054] In some embodiments, the inlet of the first heat exchanger 4 is connected to the first outlet 112a of the heating chamber through the first joint 13. The inlet of the first heat exchanger 4 is connected to the first outlet 112a of the heating chamber through the first joint 13, which is easy to operate and has a reliable sealing connection. The specific model of the first joint 13 can be set according to the inlet of the first heat exchanger 4, and is not specifically limited here. It can be understood that the first joint 13 can be used as a part of the first heat exchanger 4 or as a separate component and arranged in the first heat exchanger 4 to connect with the first outlet 112a of the heating chamber; or, the first joint 13 can also be used as a part of the housing 1 or as a separate component and arranged in the housing 1 to connect with the first heat exchanger 4. Specifically, the first joint 13 includes a male head and a female head, the male head can be used as a part of the first heat exchanger 4 or as a separate component and arranged in the first heat exchanger 4, and the female head can be used as a part of the housing 1 or as a separate component and arranged in the housing 1. The male head is connected to the female head, such as a snap connection, to connect the first heat exchanger 4 to the first outlet 112a of the heating chamber. In some specific examples, the first connector 13 is a quick-release connector to facilitate assembly and disassembly of the liquid cooling module.

[0055] In some embodiments, the valve 5 and the second outlet 112b of the heating chamber are connected through a second joint 14. The inlet of the valve 5 is connected to the second outlet 112b of the heating chamber through the second joint 14, which is easy to operate and has a reliable sealing connection. The specific model of the second joint 14 can be set according to the corresponding inlet of the valve 5, and is not specifically limited here. It can be understood that the second joint 14 can be used as a part of the valve 5 or as a separate component and arranged on the valve 5 to connect with the second outlet 112b of the heating chamber; or, the second joint 14 can also be used as a part of the housing 1, or as a separate component and arranged on the housing 1 to connect with the valve 5. Specifically, the second joint 14 includes a male head and a female head, the male head can be used as a part of the valve 5 or as a separate component and arranged on the valve 5, and the female head can be used as a part of the housing 1 or as a separate component and arranged on the housing 1. The male head is connected to the female head, such as a snap connection, to connect the valve 5 to the second outlet 112b of the heating chamber. In some specific examples, the second joint 14 is a quick-release joint to facilitate the disassembly and assembly of the liquid cooling module.

[0056] In some embodiments, the housing 1 includes a first shell portion 16 and a second shell portion 17, the first shell portion 16 forms a heating chamber 11, the second shell portion 17 forms a volute of the liquid pump 2, a liquid pump chamber 12 is formed in the volute, the impeller of the liquid pump 2 is arranged in the liquid pump chamber 12, the liquid pump inlet 121 and the liquid pump outlet 122 are respectively arranged in the liquid pump chamber 12, and the liquid pump outlet 122 is connected to the heating chamber inlet 111. The liquid pump inlet 121 and the liquid pump outlet 122 are respectively arranged in the second shell portion 17 and communicated with the liquid pump chamber 12. The liquid pump inlet 121 is also the module inlet of the liquid cooling module, and the liquid at the load end enters the liquid pump chamber 12 through the liquid pump inlet 121, and then enters the heating chamber 11 through the liquid pump outlet 122. It is understandable that the first shell 16 forms the heating chamber 11, the first shell 16 can be regarded as the outer shell of the heater, the second shell 17 can be regarded as the volute of the liquid pump 2, and the housing 1 includes the first shell 16 and the second shell 17, that is, the housing 1 integrates the volute of the liquid pump 2 and the outer shell of the heater 9, so the liquid cooling module does not need to be externally connected to the integral heater 9 and the integral liquid pump 2, which simplifies the structure and reduces the volume. It is understandable that the first shell 16 and the second shell 17 can be either an integrated structure or a split structure connected by a conventional connection method.

[0057] In some embodiments, the liquid pump cavity 12 includes a liquid pump cavity 124, a liquid inlet channel 123 and a liquid outlet channel 125, and the liquid inlet channel 123 and the liquid outlet channel 125 are respectively connected to the liquid pump cavity 124. Exemplarily, one end of the liquid pump cavity 124 is provided with an inner cavity inlet 126, which is connected to the liquid inlet channel 123. Through the arrangement of the liquid inlet channel 123 and the liquid outlet channel 125, while satisfying the integration of various components, it is convenient to layout the module inlet, so as to facilitate connection with the load end. Exemplarily, the liquid pump chamber 12 includes a liquid pump inner cavity 124, a liquid inlet channel 123 and a liquid outlet channel 125, and the heating chamber 11 is provided with a first heating chamber outlet 112a and a second heating chamber outlet 112b. In this embodiment, the flow path of the liquid cooling module is as follows: the liquid at the load end enters the liquid inlet channel 123 through the liquid pump inlet 121, enters the liquid pump inner cavity 124 from the inner cavity inlet 126 along the liquid inlet channel 123, and then enters the liquid outlet channel 125 from the liquid pump inner cavity 124, and enters the heating chamber 11 along the liquid outlet channel 125. There are two flow paths when the liquid flows out of the heating chamber 11, one flow path goes to the first heat exchanger 4 through the first heating chamber outlet 112a, and the other flow path goes to the valve 5 and the second heat exchanger 6 through the second heating chamber outlet 112b.

[0058] In some embodiments, the liquid pump chamber 12 and the heating chamber 11 are distributed in the longitudinal direction, and the liquid pump 2 and the first heat exchanger 4 are arranged on opposite sides of the housing 1. The liquid pump chamber 12 and the heating chamber 11 are distributed in the longitudinal direction, thereby making full use of the longitudinal space. The liquid pump 2 and the first heat exchanger 4 are arranged on opposite sides of the housing 1, that is, the space on both sides of the housing 1 is utilized, and the space utilization rate is high. In the case where the housing 1 is also integrated with the valve 5, the valve 5 is arranged at one end of the housing 1 in the longitudinal direction, and the layout is combined and the structure is compact.

As set above, the space is reasonably utilized, and the liquid can flow longitudinally from one end to the other end in the housing 1, and the flow resistance is small.

[0060] In some embodiments, the liquid cooling module further includes an expansion box 7, which is disposed in the liquid pump chamber 12. It is understood that the shape of the expansion box 7 can be selected as needed, such as a can or a box. By integrating the expansion box 7 into the housing 1, the integration level of the liquid cooling module is further improved.
