Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of temperature control, and more particularly, to a water chiller. BACKGROUND

[0002] With the in-depth development of the energy storage industry, air conditioning temperature control applications are becoming more and more widely used. For example, a forced air-cooled water chiller used in the energy storage industry includes a liquid pump, a heater, an evaporator, a condenser, a valve, a compressor, a fan and other devices. During installation, the compressor, condenser, evaporator and other devices are usually assembled and installed separately. For example, the compressor is first installed at the bottom of the machine frame, then the condenser is installed into the machine frame, and then the evaporator is installed inside the machine frame, and finally the copper pipes between the compressor, condenser and plate heat exchanger and other devices are welded together. After the assembly of the refrigeration system devices is completed, the assembly of the electronic control module is performed.

[0016] Optionally, in the above water chiller, the electric control box is slidably arranged in the machine frame, and the sliding direction of the electric control box is perpendicular to the direction from the first side to the second side.

[0017] Optionally, in the above water chiller, the liquid cooling module is arranged above the electric control box.

[0018] Optionally, in the above water chiller, the liquid cooling module further comprises a valve arranged in the shell, the inlet of the valve is communicated with the liquid inlet cavity, and the valve is connected with the inlet of the second heat exchanger to adjust the on-off between the liquid inlet cavity and the second heat exchanger.

[0022] The water chiller provided in the application comprises a machine frame, a fan module, a compressor, a condenser, a second heat exchanger and a liquid cooling module. The first side of the machine frame is provided with an air inlet, the second side is provided with an air outlet, and the first side is opposite to the second side. The fan module is arranged in the machine frame and is used to drive gas to flow through the inside of the machine frame from the air inlet and be discharged from the air outlet. The compressor, the condenser and the second heat exchanger are respectively arranged on one side of the machine frame close to the air outlet. The liquid cooling module is arranged on one side of the machine frame close to the air inlet.

The water chiller adopts the liquid cooling module, and the liquid pump and the first heat exchanger are integrated in the shell and do not need to be connected through pipelines. On the one hand, the compact structure of the module design reduces the space occupation, and thus the overall volume of the water chiller is small, so as to facilitate the installation in the energy storage container or other equipment. On the other hand, when the water chiller is assembled, the liquid cooling module can be directly installed in the machine frame, so that the assembly is convenient. In addition, by reasonably arranging the liquid cooling module, the compressor, the condenser and the second heat exchanger in the machine frame, the space utilization rate is further improved, and the overall volume of the water chiller is reduced.

[0024] In one approach, the valve controlling the on / off connection between the second heat exchanger and the liquid inlet chamber is also integrated into the housing. Since both the first heat exchanger and the valve are located within the housing, there is only one leakage point between the inlet of the first heat exchanger or valve and the housing. This is significantly less than if the first heat exchanger and valve were connected to the liquid pump separately via pipelines, each with a leakage point at one end of the pipeline. Therefore, the integrated design reduces the number of leakage points and improves the reliability of the chiller unit. Furthermore, the reduced number of connection points simplifies the assembly process, lowers overall material and assembly costs, and reduces the difficulty of component maintenance.

[0046] This application discloses a water chiller unit to reduce space occupation, reduce leakage points, and lower costs.

[0047] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application.

[0048] The water chiller provided by the present application is used for temperature control, and can specifically refrigerate, and can also heat according to needs. The heating principle is similar to the refrigeration principle, and heat exchange is performed through the principle of thermodynamics. For example, 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 liquid to circulate between the first heat exchanger and a load. The second heat exchanger is connected in parallel with the first heat exchanger through the valve. The liquid pump can also be used to drive liquid to circulate between the second heat exchanger and the load. The first heat exchanger is used to realize heat exchange between liquid from the load and medium at the condenser end. The heater is connected in series or parallel with the first heat exchanger to heat the liquid flowing therethrough. Specifically, high-temperature liquid heated by the heater can be used to heat the load end, that is, the heater is used to realize heating of the water chiller. When the water chiller is used to refrigerate the load end, the heater can be used to heat the liquid in combination with cooling of the liquid by the first heat exchanger and / or the second heat exchanger, so as to accurately control the temperature of the liquid sent to the load end. It should be noted that the liquid in the water chiller can be pure water, or can be added with refrigerant.

[0049] Please refer to Figure 1 , Figure 1 The figure is a schematic diagram of the principle of the water chiller of one specific embodiment of the present application. The outlet of the load end is connected with the inlet of the liquid pump 2. 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 liquid pump 2 is connected with the inlet of the first channel. The outlet of the first channel is connected with the inlet of the load end. The inlet and the outlet of the second channel are connected with the condenser 82 and the compressor 81. The first heat exchanger 4 can specifically be a plate exchanger. The outlet of the liquid pump 2 is further connected with the inlet of the second heat exchanger 6 through the valve 5. The outlet of the second heat exchanger 6 is connected with the inlet of the load end. The second heat exchanger 6 can specifically be a dry cooler to cool the liquid at the outlet of the load end. The outlet of the liquid pump 2 is further connected with the inlet of the heater 3. The outlet of the heater 3 is connected with 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 operation of the water chiller, the outlet of the liquid pump 2 can be selectively connected with one of the heater 3, the first heat exchanger 4 or the second heat exchanger 6 through the valve corresponding to the control of each device, or can be connected with different devices respectively, and the flow rates respectively connected with the corresponding devices are adjusted.

[0050] In another specific example, please refer to Figure 2 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 connected 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.

[0051] The water chiller provided by the present application integrates part of the devices in the unit, including but not limited to the heater 3, the first heat exchanger 4 such as the plate heat exchanger, the valve 5, the expansion tank, the sensor, etc., and through the reasonable and compact layout of each device and module, the volume of the water chiller is reduced, thereby facilitating the installation in the equipment.

[0052] In some embodiments, please refer to Figures 3-5 The water chiller provided by the present application includes a machine frame 20, a fan module 30, a compressor 81, a condenser 82, a second heat exchanger 6, and a liquid cooling module 10. The first side of the machine frame 20 is provided with an air inlet 21, and the second side is provided with an air outlet 22, and the first side is opposite to the second side. That is, the air inlet 21 and the air outlet 22 are respectively arranged on the opposite sides of the machine frame 20. For example, the air inlet 21 is arranged on the front surface of the machine frame 20, and the air outlet 22 is arranged on the back surface of the machine frame 20. The fan module 30 is arranged in the machine frame 20, and the fan module 30 is used to drive the gas to flow through the inside of the machine frame 20 from the air inlet 21 and be discharged from the air outlet 22. Under the action of the fan module 30, the flow direction of the air in the machine frame 20 is from the first side to the second side. It can be understood that the number of fans in the fan module 30 can be set as needed, which can be one fan or multiple fans. The compressor 81, the condenser 82, and the second heat exchanger 6 are respectively arranged on the side of the machine frame 20 close to the air outlet 22.

[0053] The liquid cooling module 10 is arranged on the side of the machine frame 20 close to the air inlet 21, please refer to Figures 6-8The liquid cooling module 10 comprises a shell 1, a liquid pump 2 and a first heat exchanger 4 arranged in the shell 1, the shell 1 is formed with a liquid inlet cavity 11, the outlet of the liquid pump 2 is communicated with the liquid inlet cavity 11, the inlet of the first heat exchanger 4 is communicated with the liquid inlet cavity 11, the compressor 81 and the condenser 82 are communicated with the first heat exchanger 4 to exchange heat with the inlet of the second heat exchanger 6, the outlet of the first heat exchanger 4 and the outlet of the second heat exchanger 6 are used to be communicated with the load end. The shell 1 is formed with a liquid inlet cavity 11, the shell 1 is the main integrated structure of the liquid cooling module 10, and is used for centrally arranging the liquid pump 2 and other devices. It can be understood that the shell 1 can be an integrated structure or a split structure connected by a conventional sealing mode. In an example, the shell 1 is an integrated structure, that is, it is integrally formed, and has excellent sealing performance. In another example, the shell 1 is a split structure, comprising a base and a shell cover, and the base is sealingly connected with the shell cover. The shape and size of the liquid inlet cavity 11 are not limited in the embodiment, and can be set as required.

[0054] The liquid pump 2 is arranged in the shell 1, the inlet of the liquid pump 2 is used to be connected with the load end, the outlet of the liquid pump 2 is communicated with the liquid inlet cavity 11, and the liquid inlet cavity 11 is provided with a liquid inlet 111, and the outlet of the liquid pump 2 is arranged at the liquid inlet 111. The inlet of the first heat exchanger 4 is arranged in the shell 1 and communicated with the liquid inlet cavity 11, and it should be noted that the liquid pump 2 and the first heat exchanger 4 arranged in the shell 1 respectively means that the liquid pump 2 and the first heat exchanger 4 are respectively mounted in the shell 1, and are not connected with the shell 1 through a pipeline. The compressor 81 and the condenser 82 are communicated with the first heat exchanger 4 to exchange heat, and the connection relationship thereof can refer to the above embodiment and Figure 1 And Figure 2 For example, the compressor 81 and the condenser 82 are sequentially connected between the outlet of the second channel of the first heat exchanger 4 and the inlet thereof through a pipeline. It can be understood that the inlet of the first heat exchanger 4 arranged in the shell 1 refers to the inlet of the first heat exchanger 4 communicated with the load end, that is, the inlet of the first channel described above, and the compressor 81 and the condenser 82 are connected with the second channel.

[0055] The outlet of the first heat exchanger 4 and the outlet of the second heat exchanger 6 are used to be communicated with the load end, and it can be understood that they can be connected with the load end through a pipeline, or a liquid outlet cavity 12 can be arranged in the shell 1, and the outlet of the first heat exchanger 4 and the outlet of the second heat exchanger 6 are also integrated in the shell 1.

[0056] The water chiller provided by the application can be installed in the frame 20 in advance, and the water chiller is installed in the energy storage container and the like as a whole. The water chiller adopts the liquid cooling module 10, and the liquid pump 2 and the first heat exchanger 4 are integrated in the shell 1, without the need for connection through pipelines. On the one hand, the compact design structure of the module reduces the space occupation, and the overall volume of the water chiller is relatively small, so as to facilitate the installation in the energy storage container and the like. On the other hand, when the water chiller is assembled, the liquid cooling module 10 can be directly installed in the frame 20, and the assembly is convenient. In addition, through the reasonable space layout of the liquid cooling module 10, the compressor 81, the condenser 82 and the second heat exchanger 6 in the frame 20, the space utilization is further improved, and the overall volume of the water chiller is reduced.

[0057] In some embodiments, the water chiller comprises an inlet pipe 40 and an outlet pipe 50, the inlet pipe 40 is communicated with the inlet of the liquid pump 2, and the outlet pipe 50 is communicated with the outlet of the first heat exchanger 4 and the outlet of the second heat exchanger 6. It can be understood that the outlet pipe 50 can be used as a main pipe and connected with the outlet of the first heat exchanger 4 and the outlet of the second heat exchanger 6 through branch pipes, or the shell 1 can be provided with an outlet cavity 12, the outlet of the first heat exchanger 4 and the outlet of the second heat exchanger 6 are arranged in the outlet cavity 12, and the outlet pipe 50 is connected with the shell 1 and communicated with the outlet cavity 12. The inlet pipe 40 is used for connecting with the outlet of the load end, and the outlet pipe 50 is used for connecting with the inlet of the load end, so as to realize the circulation of the liquid. The inlet pipe 40 and the outlet pipe 50 are arranged at the top of the first side, which can provide a relatively large operation space for the operation of connecting with the load end, facilitate the connection with the load end, and better adapt to the height of the load end.

[0058] In some embodiments, the compressor 81, the second heat exchanger 6 and the condenser 82 are arranged in sequence from the first side to the second side. The volumes of the compressor 81, the second heat exchanger 6 and the condenser 82 are relatively large, and they are arranged in sequence from the first side to the second side, so as to realize the full use of the space. In addition, the compressor 81, the second heat exchanger 6 and the condenser 82 are arranged in sequence, and the air can more fully contact and exchange heat with them when flowing through the inside of the frame 20, so as to take away the heat generated in the working process.

[0059] For example, the second heat exchanger 6 and the condenser 82 are arranged obliquely relative to the second side wall of the frame 20. Since the widths of the second heat exchanger 6 and the condenser 82 are generally large, the oblique arrangement of the second heat exchanger 6 and the condenser 82 can be arranged in the frame 20 with a smaller width, that is, the overall layout of the water chiller is more compact, and the space is further saved.

[0060] In some embodiments, the machine frame 20 comprises an outer frame 23 and a support beam 24 arranged in the outer frame 23, the support beam 24 divides the inner part of the outer frame 23 into a first mounting area 25 and a second mounting area 26, the first mounting area 25 and the second mounting area 26 are arranged in sequence along the direction from the first side to the second side, the liquid cooling module 10 is arranged in the first mounting area 25, and the compressor 81, the condenser 82 and the second heat exchanger 6 are arranged in the second mounting area 26. For example, the outer frame 23 comprises two side parts arranged at the first side and the second side, and a top part and a bottom part connected between the two side parts, so as to Figure 4 As shown in the direction, the outer frame 23 surrounds each device in the up-down and left-right directions, and the front-rear direction can be arranged in an open manner. According to needs, the machine frame 20 can also comprise a front part and / or a rear part arranged at the front and rear ends of the outer frame 23. It can be understood that any one of the side part, the top part, the bottom part, the front part and the rear part can be a plate member or a frame structure. The support beam 24 is arranged in the outer frame 23, which can play a role in strengthening the stability of the overall structure, and on the other hand, it can divide the inner part of the outer frame 23 into two mounting areas, i.e. the first mounting area 25 and the second mounting area 26, thereby facilitating the installation of each device, such as the fixation and positioning of each device during assembly, and the corresponding device can be fixed to the support beam 24 or positioned by the support beam 24.

[0061] In some embodiments, the water chiller further comprises an electric control box 60 for controlling the operation of the water chiller, and the electric control box 60 is arranged in the machine frame 20 and close to the first side. On the one hand, the electric control box 60 has a relatively small volume compared with the liquid cooling module 10, so they are both arranged close to the first side, thereby achieving full utilization of space, and the electric control box 60 is also integrated into the machine frame 20, which further facilitates the assembly of the water chiller in the equipment. On the other hand, the control elements in the electric control box 60 generate a large amount of heat during operation, and arranging the electric control box 60 close to the air inlet 21 can preferentially cool the control elements by the ambient air, thereby improving the heat dissipation efficiency of the electric control box 60 and ensuring reliable operation.

[0062] In some embodiments, the electric control box 60 is slidably arranged in the machine frame 20. When the control elements in the electric control box 60 need to be repaired or replaced, the electric control box 60 can be easily pulled out of the machine frame 20, and after the repair or replacement is completed, the electric control box 60 can be pushed back into the machine frame 20, which greatly facilitates the maintenance of the control elements. For example, the sliding direction of the electric control box 60 is perpendicular to the direction from the first side to the second side, so the electric control box 60 can be arranged in avoidance of the air inlet 21 and the air outlet 22, thereby achieving full utilization of space and making the overall structure of the water chiller more compact.

[0063] In some embodiments, the liquid cooling module 10 is arranged above the electric control box 60. As arranged above, the inlet and outlet of the water chiller connected with the load end can be arranged above the machine frame 20, so as to facilitate the connection with the load end. In addition, the pipeline connection between the devices, i.e. the electrical connection between the electric control box 60 and the corresponding devices, is facilitated, and the overall space layout is more compact.

[0064] Referring to Figures 6-8 In some embodiments, the liquid cooling module 10 further comprises a valve 5 arranged in the shell 1. The inlet of the valve 5 is in communication with the liquid inlet cavity 11, and the valve 5 is connected with the inlet of the second heat exchanger 6 to regulate the on-off between the liquid inlet cavity 11 and the second heat exchanger 6. It should be noted that the valve 5 arranged in the shell 1 means that the valve 5 is installed in the shell 1, and is not connected with the shell 1 through a pipeline. Integrating the valve 5 that controls the communication between the second heat exchanger 6 and the liquid inlet cavity 11 in the shell also makes the degree of integration of the liquid cooling module 10 higher, the overall structure more compact, and the space occupation smaller. In addition, the first heat exchanger 4 and the valve 5 are both arranged in the shell 1, and there is only one leakage point between the inlet of the first heat exchanger 4 or the valve 5 and the shell 1. Compared with the case where the first heat exchanger 4 and the valve 5 are respectively connected with the liquid pump 2 through a pipeline, there is one leakage point at each end of the pipeline, so the integrated arrangement reduces the number of leakage points and improves the reliability of the water chiller. In addition, the reduction in the number of connection points also simplifies the assembly process, reduces the overall material cost and assembly cost, and reduces the difficulty of device maintenance.

[0065] Referring to Figures 6-8 In some embodiments, the liquid cooling module 10 further comprises a heating component 31 arranged in the liquid inlet cavity 11. In this embodiment, the first heat exchanger 4 and the heater 3 are connected in series, and the heating component 31 is arranged in the liquid inlet cavity 11, i.e. the shell 1 and the heating component 31 constitute the heater 3, and the first heat exchanger 4 is integrated therewith, so that the shell 1 does not need to be connected with the heater 3 having a liquid flow passage, further simplifying the structure and improving the degree of integration of the liquid cooling module 10, so that the space occupation is smaller. For example, the liquid inlet cavity 11 is provided with a liquid inlet first outlet 112a, and the inlet of the first heat exchanger 4 is arranged at the liquid inlet first outlet 112a, i.e. the inlet of the first heat exchanger 4 is installed at the liquid inlet first outlet 112a and is not connected through a pipeline. Then, the liquid can flow into the first heat exchanger 4 after passing through the liquid inlet cavity 11. When the heating component 31 is started and the first heat exchanger 4 is not working, the liquid is heated by the heating component 31 and then flows through the first heat exchanger 4 and returns to the load end. When the first heat exchanger 4 is working, the heating component 31 can not be started, the liquid passes through the liquid inlet cavity 11, enters the first heat exchanger 4 and is cooled, and then returns to the load end. Alternatively, according to the temperature of the liquid, the heating component 31 can be controlled to work to heat the liquid, so that the liquid entering the load end can meet the preset cooling temperature.

[0066] In some embodiments, the shell 1 is provided with a window, the window is in communication with the heating cavity 11, the heating component 31 comprises a mounting portion and a heating fin, the mounting portion covers the window and is sealingly connected with the shell 1, and the heating fin is arranged on the mounting portion and located in the heating cavity. By providing the window on the shell 1, the heating fin of the heating component 31 can be inserted into the heating cavity 11, and the mounting portion is sealingly connected with the shell 1 to prevent liquid leakage. As arranged above, the assembly is facilitated. For example, the mounting portion is bolted with the shell 1, and a sealing ring is arranged between the mounting portion and the shell 1 to seal.

[0067] In some embodiments, referring to Figures 6-8 , the liquid inlet cavity 11 is provided with a liquid inlet valve outlet 112c, the inlet of the valve 5 is arranged at the liquid inlet valve outlet 112c, and the outlet of the valve 5 is connected with the inlet of the second heat exchanger 6, that is, the inlet of the second heat exchanger 6 is indirectly connected with the liquid inlet cavity 11 by being connected with the valve 5, the valve 5 is simple to assemble, and is convenient to connect with the second heat exchanger 6, and the connection and disconnection between the liquid inlet cavity 11 and the second heat exchanger 6 is directly controlled by the valve 5. In other embodiments, the liquid inlet valve outlet 112c is connected with the inlet of the second heat exchanger 6, for example, by being connected by a pipeline, and the valve 5 is arranged on the shell and is used to control the connection and disconnection between the liquid inlet cavity 11 and the liquid inlet valve outlet 112c. In this embodiment, the liquid inlet valve outlet 112c is arranged to be connected with the inlet of the second heat exchanger 6 by a pipeline, which is convenient for the layout of the second heat exchanger 6.

[0068] In some embodiments, the liquid inlet cavity 11 is provided with a liquid inlet inlet 111, the liquid pump 2 is arranged on the shell 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 arranged at the liquid inlet inlet 111. It should be noted that the liquid pump 2 arranged at the liquid inlet inlet 111 means that the liquid pump 2 is mounted at the liquid inlet inlet 111, rather than being connected with the liquid inlet inlet 111 by a pipeline. The liquid pump 2 can pump the liquid at the load end to the liquid inlet cavity 11, and then to the corresponding first heat exchanger 4 or the valve 5 and the second heat exchanger 6 connected with the valve 5 through the liquid inlet cavity 11, so as to be heated by the heating component 31, or be cooled by the first heat exchanger 4 or the second heat exchanger 6, and then flow back to the load end, completing a cycle.

[0069] The liquid pump 2, the valve 5 and the heating component 31 are integrated by the shell 1, and the first heat exchanger 4 or the valve 5 and other devices can be mounted on the shell 1 without using a pipeline, so that the liquid cooling system does not need to install the liquid pump 2, the heating component 31 and the corresponding liquid inlet and outlet pipe fittings during on-site assembly, thereby reducing the number of devices for on-site assembly of the liquid cooling system, simplifying the assembly process, reducing the overall material cost and assembly cost, and compacting the modular design structure to reduce the overall space occupation.

[0070] In some embodiments, referring to Figures 6-8The housing 1 includes a first housing portion 14 and a second housing portion 15. The first housing portion 14 forms a heating chamber, and the second housing portion 15 forms a volute of the liquid pump 2. A liquid pump chamber 13 is formed inside the volute. The liquid pump chamber 13 includes a liquid pump inner cavity 134, a liquid inlet channel 133, and a liquid outlet channel 135. The liquid inlet channel 133 and the liquid outlet channel 135 are respectively connected to the liquid pump inner cavity 134. The impeller of the liquid pump 2 is disposed in the liquid pump inner cavity 134. The opening of the liquid inlet channel 133 extending to the end face of the second housing portion 15 forms a liquid pump inlet 131, and the opening of the liquid outlet channel 135 extending to the end face of the second housing portion 15 forms a liquid pump outlet 132. It is understood that the first shell portion 14 forms the liquid inlet chamber 11, and the first shell portion 14 can be regarded as the outer shell of the heater 3. The second shell portion 15 can be regarded as the volute of the liquid pump 2. The housing 1 includes the first shell portion 14 and the second shell portion 15, that is, the housing 1 integrates the volute of the liquid pump 2 and the outer shell of the heater 3. Therefore, the liquid cooling module 10 does not need to be connected to an external integrated heater 3 and an integrated liquid pump 2, which simplifies the structure and reduces the volume. It is understood that the first shell portion 14 and the second shell portion 15 can be either an integral structure or a separate structure connected by a conventional connection method.

[0071] For example, one end of the liquid pump cavity 134 is provided with an inner cavity inlet 136, which communicates with the liquid inlet channel 133. The arrangement of the liquid inlet channel 133 and the liquid outlet channel 135 not only satisfies the integration of various devices, but also facilitates the layout of the liquid pump inlet 131, thereby facilitating connection with the load end. For example, the liquid pump chamber 13 includes a liquid pump inner chamber 134, a liquid inlet channel 133, and a liquid outlet channel 135. The liquid inlet chamber 11 is provided with a first liquid inlet outlet 112a and a liquid inlet valve outlet 112c. In this embodiment, the flow path of the liquid cooling module 10 is as follows: the liquid at the load end enters the liquid inlet channel 133 through the liquid pump inlet 131, enters the liquid pump inner chamber 134 through the inner chamber inlet 136 along the liquid inlet channel 133, enters the liquid outlet channel 135 through the liquid pump inner chamber 134, and enters the liquid inlet chamber 11 along the liquid outlet channel 135. When the liquid flows out of the liquid inlet chamber 11, there are two flow paths: one flow path goes to the first heat exchanger 4 through the first liquid inlet outlet 112a, and the other flow path goes to the valve 5 and the second heat exchanger 6 through the liquid inlet valve outlet 112c.

[0072] Please see Figures 9-14 In other embodiments, the heater 3 and the first heat exchanger 4 are both integrated into the housing 1, and the heater 3 and the first heat exchanger 4 are connected in parallel. Specifically, the liquid cooling module 10 also includes a heater 3, and the liquid inlet chamber 11 is provided with a first liquid inlet outlet 112a and a second liquid inlet outlet 112b. The inlet of the heater 3 is located at the first liquid inlet outlet 112a, and the inlet of the first heat exchanger 4 is located at the second liquid inlet outlet 112b. In this embodiment, integrating the liquid pump 2, the first heat exchanger 4, and the heater 3 into the housing 1, and connecting the first heat exchanger 4 and the heater 3 in parallel, can also reduce space occupation.

[0073] To control the flow rate of the liquid in the liquid inlet cavity 11 into the heater 3 and into the first heat exchanger 4, the outlet of the heater 3 can be connected with a valve, such as an on-off valve or a flow valve. In an example, a flow valve is provided between the outlet of the heater 3 and the load end. The flow rate of the liquid flowing from the liquid inlet cavity 11 into the load end through the heater 3 can be adjusted by the flow valve, so that the liquid in the liquid inlet cavity 11 enters the heater 3 and the first heat exchanger 4 in a proper proportion, thereby achieving accurate regulation of the outlet liquid temperature, or the liquid in the liquid inlet cavity 11 does not flow into the heater 3 but enters the first heat exchanger 4 entirely. In another example, an on-off valve can also be provided between the outlet of the heater 3 and the load end. The on-off valve can control the connection between the branch of the heater 3 and the load end. It can be understood that, in the case where the above-mentioned valve for controlling the flow rate of the heater 3 is not provided, the outlet liquid temperature of the first heat exchanger 4 can also be adjusted to meet the demand of the liquid flowing into the load end.

[0074] In some embodiments, referring to Figures 12-14 , the liquid inlet cavity 11 is further provided with a liquid inlet valve outlet 112c, the inlet of the second heat exchanger 6 is connected to the liquid inlet valve outlet 112c through a pipeline, and the valve 5 is arranged in the shell 1 and used to control the connection between the liquid inlet cavity 11 and the liquid inlet valve outlet 112c. In this example, the liquid pump 2, the heater 3, the first heat exchanger 4 and the valve 5 are all integrated in the shell 1, so that the structure is more compact and the space occupation is smaller.

[0075] In some embodiments, the shell 1 is further formed with a liquid outlet cavity 12, the liquid outlet cavity 12 is provided with a liquid outlet first inlet 121a, a liquid outlet second inlet 121b and a liquid outlet valve inlet 121c, the outlet of the heater 3 is arranged at the liquid outlet first inlet 121a, the outlet of the first heat exchanger 4 is arranged at the liquid outlet second inlet 121b, and the outlet of the second heat exchanger 6 is connected to the liquid outlet valve inlet 121c through a pipeline. The liquid outlet cavity 12 is provided with a module outlet 122 to be connected to the load end through a pipeline. As described above, the liquid outlets of the first heat exchanger 4, the second heat exchanger 6 and the heater 3 are all integrated in the shell 1, so that the integration degree is further improved, the overall material cost and assembly cost are reduced, the overall space occupation is reduced, the number of leakage points is reduced, and the reliability of the liquid cooling module 10 is improved.

[0076] Further, to control the flow rate of the liquid in the liquid inlet cavity 11 into the heater 3, the heater 3 includes a heater body and a valve, such as a flow valve or an on-off valve, connected to the heater body, that is, the heater body and the valve for controlling the flow rate thereof are integrated in the shell 1. The valve can control the flow rate of the liquid in the liquid inlet cavity 11 flowing through the heater body and into the liquid outlet cavity 12, thereby achieving accurate regulation of the outlet liquid temperature. The flow rate adjustment mode of the on-off valve or the flow valve can refer to the above-mentioned embodiments, which will not be described herein again.

[0077] In some embodiments, the liquid cooling module 10 further comprises a temperature detecting device 91 arranged in the outlet cavity 12. The temperature detecting device 91 is arranged to detect the temperature of the liquid in the outlet cavity 12, so as to accurately control the outlet temperature of the water chiller. The temperature detecting device 91 is exemplarily a temperature sensor. By integrating the temperature detecting device 91 in the housing 1, the integration level of the liquid cooling module 10 is further improved.

[0078] In some embodiments, the liquid cooling module 10 further comprises a pressure detecting device 92 arranged in the outlet cavity 12. The pressure detecting device 92 is arranged to detect the pressure of the liquid in the outlet cavity 12, so as to accurately control the outlet pressure of the water chiller. The pressure detecting device 92 is exemplarily a pressure sensor. By integrating the pressure detecting device 92 in the housing 1, the integration level of the liquid cooling module 10 is further improved. The temperature detecting device 91 and the pressure detecting device 92 are exemplarily integrated, i.e. a temperature-pressure integrated sensor is arranged in the outlet cavity 12.

[0079] In other embodiments, only the inlet of the devices is integrated in the housing 1, i.e. the inlet of the first heat exchanger 4 and the valve 5 are integrated with the liquid pump 2, while the outlet of the devices, i.e. the outlet of the first heat exchanger 4 and the second heat exchanger 6, is not integrated in the housing 1, i.e. the liquid from the load is integrated, while the liquid to the load is not integrated, and is sent to the load through corresponding pipelines, so as to avoid the heat conduction between the liquid from the load and the liquid to the load, and avoid the mutual influence between the two, so as to ensure the working efficiency of the liquid cooling system.
