[0023] 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.

[0024] The chiller provided in the present application 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, and 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, that is, the heater is used to realize the heating of the chiller; when the chiller is used to cool the load end, the liquid can also be heated by the heater in combination with the cooling of the liquid by the first heat exchanger and / or the second heat exchanger to accurately control the temperature of the liquid sent to the load end. It should be noted that the liquid in the chiller can be pure water or a refrigerant can be added.

[0025] See also Figure 1 , Figure 1The schematic diagram of the principle of a chiller of a specific embodiment of the present application. 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, the inlet and outlet of the second channel are connected with a condenser 82 and a compressor 81, and 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. The outlet of the liquid pump 2 is also connected to the inlet of the heater 3, and 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 operation of the chiller, 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 that control each device, or it can be connected to different devices respectively and the flow rates connected to the corresponding devices can be adjusted.

[0026] In another specific example, see 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 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.

[0027] The chiller provided in the present application integrates some components in the unit, including but not limited to the heater 3, the first heat exchanger 4 such as a plate heat exchanger, the valve 5, the expansion tank, the sensor, etc., and reduces the volume of the chiller through a reasonable and compact layout of the components and modules, thereby facilitating installation in the equipment.

[0028] In some embodiments, see Figure 3-Figure 5The chiller provided in the present application includes a frame 20, a fan module 30, a compressor 81, a condenser 82, a second heat exchanger 6 and a liquid cooling module 10. Among them, an air inlet 21 is provided on the first side of the frame 20, an air outlet 22 is provided on the second side, and the first side is opposite to the second side. That is, the air inlet 21 and the air outlet 22 are respectively provided on the opposite sides of the frame 20. Exemplarily, the air inlet 21 is provided on the front of the frame 20, and the air outlet 22 is provided on the back of the frame 20. The fan module 30 is provided in the frame 20, and the fan module 30 is used to drive the gas to flow through the inside of the 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 wind in the 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, and it can be provided with one fan or multiple fans. The compressor 81 , the condenser 82 , and the second heat exchanger 6 are respectively disposed on one side of the frame 20 close to the air outlet 22 .

[0029] The liquid cooling module 10 is disposed on one side of the frame 20 near the air inlet 21, see Figure 6-Figure 8 The liquid cooling module 10 includes a shell 1 and a liquid pump 2 and a first heat exchanger 4 arranged in the shell 1. A liquid inlet cavity 11 is formed in the shell 1. The outlet of the liquid pump 2 is connected to the liquid inlet cavity 11, and the inlet of the first heat exchanger 4 is connected to the liquid inlet cavity 11. The compressor 81 and the condenser 82 are connected to the first heat exchanger 4 for heat exchange. The inlet of the second heat exchanger 6 is connected to the liquid inlet cavity 11, and the outlets of the first heat exchanger 4 and the second heat exchanger 6 are used to communicate with the load end. A liquid inlet cavity 11 is formed in the shell 1. The shell 1 is the main integrated structure of the liquid cooling module 10, which is used to centrally arrange the components such as the liquid pump 2. It can be understood that the shell 1 can be an integrated structure or a split structure connected by a conventional sealing method. In one example, the shell 1 is an integrated 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 cavity 11 are not specifically limited in this embodiment and can be set as required.

[0030] The liquid pump 2 is arranged in the housing 1, and the inlet of the liquid pump 2 is used to connect to the load end, and the outlet of the liquid pump 2 is connected to the liquid inlet chamber 11. For example, the liquid inlet chamber 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 housing 1 and is connected to the liquid inlet chamber 11. It should be noted that the liquid pump 2 and the first heat exchanger 4 are respectively arranged in the housing 1, which means that the liquid pump 2 and the first heat exchanger 4 are respectively installed in the housing 1, and are not connected to the housing 1 through pipelines. The compressor 81 and the condenser 82 are connected to the first heat exchanger 4 for heat exchange. For specific connection relationships, please refer to the above embodiments and Figure 1 and Figure 2, illustratively, the compressor 81 and the condenser 82 are connected in sequence between the outlet and the inlet of the second channel of the first heat exchanger 4 through pipelines. It can be understood that the inlet of the first heat exchanger 4 provided in the shell 1 refers to the inlet of the first heat exchanger 4 connected to the load end, that is, the inlet of the first channel mentioned above, and the compressor 81 and the condenser 82 are connected to the second channel.

[0031] The outlets of the first heat exchanger 4 and the second heat exchanger 6 are used to communicate with the load end. It can be understood that they can be connected to the load end through a pipeline, or a liquid outlet cavity 12 can be set in the shell 1, and the outlets of the first heat exchanger 4 and the second heat exchanger 6 can also be integrated into the shell 1.

[0032] By using the chiller provided by the present application, each device can be pre-installed in the frame 20, and then the chiller can be installed as a whole in equipment such as energy storage containers. The chiller adopts a liquid cooling module 10, and the liquid pump 2 and the first heat exchanger 4 are integrated into the housing 1, without the need to be connected through pipelines. On the one hand, the module design structure is compact, which reduces the space occupied, and the overall volume of the chiller is small, so that it is easy to install in equipment such as energy storage containers. On the other hand, when the chiller is assembled, the liquid cooling module 10 can be directly installed in the frame 20, which is convenient for assembly. In addition, through the reasonable spatial 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 rate is further improved and the overall volume of the chiller is reduced.

[0033] In some embodiments, the chiller includes a liquid inlet pipe 40 and a liquid outlet pipe 50, the liquid inlet pipe 40 is connected to the inlet of the liquid pump 2, and the liquid outlet pipe 50 is connected to the outlet of the first heat exchanger 4 and the outlet of the second heat exchanger 6. It can be understood that the liquid outlet pipe 50 can be used as a main pipe and connected to the outlet of the first heat exchanger 4 and the outlet of the second heat exchanger 6 through a branch pipe, or the shell 1 can be configured to form a liquid outlet cavity 12, the outlet of the first heat exchanger 4 and the outlet of the second heat exchanger 6 are respectively arranged in the liquid outlet cavity 12, and the liquid outlet pipe 50 is connected to the shell 1 and communicated with the liquid outlet cavity 12. The liquid inlet pipe 40 is used to connect to the outlet of the load end, and the liquid outlet pipe 50 is used to connect to the inlet of the load end to realize liquid circulation. The liquid inlet pipe 40 and the liquid outlet pipe 50 are respectively arranged at the top of the first side, which can provide a relatively large operating space for the operation of connecting to the load end, facilitate connection to the load end, and can better adapt to the height of the load end.

[0034] 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 compressor 81, the second heat exchanger 6, and the condenser 82 are relatively large in volume, and they are arranged in sequence from the first side to the second side to achieve full utilization of the space. In addition, the compressor 81, the second heat exchanger 6, and the condenser 82 are arranged in sequence, and the wind can more fully contact and exchange heat with the frame 20 when flowing through the inside of the frame 20 to take away the heat generated during its working process.

[0035] Exemplarily, the second heat exchanger 6 and the condenser 82 are arranged at an angle relative to the second side wall of the frame 20. Since the width of the second heat exchanger 6 and the condenser 82 is usually large, the two are arranged at an angle so that they can be arranged in the frame 20 with a smaller width, that is, the overall layout of the chiller is more compact, further saving space.

[0036] In some embodiments, the frame 20 includes an outer frame 23 and a support beam 24 disposed in the outer frame 23. The support beam 24 divides the interior of the outer frame 23 into a first installation area 25 and a second installation area 26. The first installation area 25 and the second installation area 26 are sequentially distributed from the first side to the second side. The liquid cooling module 10 is disposed in the first installation area 25, and the compressor 81, the condenser 82, and the second heat exchanger 6 are disposed in the second installation area 26. Exemplarily, the outer frame 23 includes two side portions disposed on the first side and the second side and a top and a bottom portion connected between the two side portions. Figure 4 In the direction shown, the outer frame 23 surrounds each device from the up, down, left and right directions, and the front and back directions can be open. As needed, the frame 20 can also include a front and / or rear portion arranged at the front and back ends of the outer frame 23. It can be understood that any one of the side, top, bottom, front and rear portions can be either a plate or a frame structure. The support beam 24 is arranged on the outer frame 23, which can play a role in strengthening the stability of the overall structure on the one hand, and on the other hand, it is convenient to divide the interior of the outer frame 23 into two installation areas, namely the first installation area 25 and the second installation area 26, so as to facilitate the installation of each device, such as the fixing of each device and the positioning during assembly. The corresponding device can be fixed to the support beam 24 or positioned by the support beam 24.

[0037] In some embodiments, the chiller also includes an electric control box 60 for controlling the operation of the chiller, and the electric control box 60 is arranged in the frame 20 and close to the first side. On the one hand, the volume of the electric control box 60 and the liquid cooling module 10 is relatively small, so both are arranged close to the first side to achieve full utilization of space, and the electric control box 60 is also integrated into the frame 20, which further facilitates the assembly of the chiller in the device. On the other hand, the control components in the electric control box 60 generate a lot of heat during operation. If it is installed close to the air inlet 21, the ambient air intake can give priority to cooling it, which improves the heat dissipation efficiency of the electric control box 60, thereby ensuring its reliable operation.

[0038] In some embodiments, the electric control box 60 is slidably disposed on the frame 20. When the electric control box 60 is slidably mounted on the frame 20, when the control elements in the electric control box 60 need to be inspected or replaced, the electric control box 60 can be conveniently pulled out from the inside of the frame 20, and the electric control box 60 can be pushed back into the frame 20 after the inspection or replacement is completed, which greatly facilitates the maintenance of the control elements. Exemplarily, the sliding direction of the electric control box 60 is perpendicular to the direction from the first side to the second side, so that the electric control box 60 can be arranged away from the air inlet 21 and the air outlet 22, so that the space is fully utilized, making the overall structure of the chiller more compact.

[0039] In some embodiments, the liquid cooling module 10 is disposed above the electric control box 60. As above, the inlet and outlet of the chiller connected to the load end can be disposed above the frame 20, so as to facilitate connection with the load end. In addition, it is convenient to connect the pipelines between the components, that is, the electrical connection between the electric control box 60 and the corresponding components, and the overall spatial layout is more compact.

[0040] See also Figure 6-Figure 8 In some embodiments, the liquid cooling module 10 further includes a valve 5 disposed on the housing 1, the inlet of the valve 5 is connected to the liquid inlet chamber 11, and the valve 5 is connected to the inlet of the second heat exchanger 6 to adjust the on-off between the liquid inlet chamber 11 and the second heat exchanger 6. It should be noted that the valve 5 disposed on the housing 1 means that the valve 5 is installed on the housing 1, and is not connected to the housing 1 through a pipeline. The valve 5 that controls the communication between the second heat exchanger 6 and the liquid inlet chamber 11 is also integrated into the housing, so that the liquid cooling module 10 has a higher degree of integration, a more compact overall structure, and a smaller space occupation. In addition, the first heat exchanger 4 and the valve 5 are both disposed on the housing 1, and there is only one leakage point between the inlet of the first heat exchanger 4 or the valve 5 and the housing 1. Compared with the first heat exchanger 4 and the valve 5 being connected to the liquid pump 2 through a pipeline respectively, there is a leakage point at each end of the pipeline, so the integrated setting reduces the number of leakage points and improves the reliability of the 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.

[0041] See also Figure 6-Figure 8In some embodiments, the liquid cooling module 10 further includes a heating component 31, and the heating component 31 is disposed 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 placed in the liquid inlet cavity 11, that is, the housing 1 and the heating component 31 form the heater 3, and the first heat exchanger 4 is integrated with the heater 3, so that the housing 1 does not need to be connected to the heater 3 with a liquid flow channel, which further simplifies the structure, improves the integration level of the liquid cooling module 10, and makes it occupy less space. Exemplarily, the liquid inlet chamber 11 is provided with a first liquid inlet outlet 112a, and the inlet of the first heat exchanger 4 is provided at the first liquid inlet outlet 112a, that is, the inlet of the first heat exchanger 4 is installed at the first liquid inlet outlet 112a, and is not connected by a pipeline, so that the liquid can flow into the first heat exchanger 4 after passing through the liquid inlet chamber 11, and 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 flows back to the load end; when the first heat exchanger 4 is working, the heating component 31 can be not started, and the liquid enters the first heat exchanger 4 after passing through the liquid inlet chamber 11 and flows back to the load end after being cooled, or the heating component 31 can be controlled to work accordingly according to the temperature of the liquid to heat the liquid, so that the liquid entering the load end can meet the preset cooling temperature.

[0042] In some embodiments, the housing 1 is provided with a window, the window is connected to the heating chamber 11, the heating component 31 includes a mounting portion and a heating fin, the mounting portion covers the window and is sealed with the housing 1, the heating fin is provided on the mounting portion, and the heating fin is located in the heating chamber. By providing a window on the housing 1, the heating fin of the heating component 31 can be inserted into the heating chamber 11, and the mounting portion is sealed with the housing 1 to prevent liquid leakage. As set above, it is easy to assemble. Exemplarily, the mounting portion is bolted to the housing 1, and a sealing ring is provided between the mounting portion and the housing 1 to seal.

[0043] In some embodiments, see Figure 6-Figure 8 , the liquid inlet chamber 11 is provided with a liquid inlet valve outlet 112c, the inlet of the valve 5 is provided at the liquid inlet valve outlet 112c, and the outlet of the valve 5 is connected to the inlet of the second heat exchanger 6, that is, the inlet of the second heat exchanger 6 is indirectly connected to the liquid inlet chamber 11 by connecting to the valve 5, the valve 5 is simple to assemble, and is convenient to connect to the second heat exchanger 6, and the connection and disconnection between the liquid inlet chamber 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 to the inlet of the second heat exchanger 6, specifically, by a pipeline, and the valve 5 is provided in the housing and is used to control the connection and disconnection between the liquid inlet chamber 11 and the liquid inlet valve outlet 112c. In this embodiment, by setting the liquid inlet valve outlet 112c to be connected to the inlet of the second heat exchanger 6 through a pipeline, etc., the layout of the second heat exchanger 6 is facilitated.

[0044] In some embodiments, the liquid inlet chamber 11 is provided with a liquid inlet 111, the liquid pump 2 is provided 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 provided at the liquid inlet 111. It should be noted that the liquid pump 2 is provided at the liquid inlet 111, which means that the liquid pump 2 is installed at the liquid inlet 111, and is not connected to the liquid inlet 111 through a pipeline. The liquid pump 2 can pump the liquid at the load end to the liquid inlet chamber 11, and enter the corresponding first heat exchanger 4 or valve 5 and the second heat exchanger 6 connected to the valve 5 through the liquid inlet chamber 11, so as to be heated by the heating component 31, 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.

[0045] The liquid pump 2, the valve 5 and the heating component 31 are integrated through the shell 1, and the first heat exchanger 4 or the valve 5 and other devices can be installed 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 component 31 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, which reduces the overall space occupancy.

[0046] In some embodiments, see Figure 6-Figure 8 The shell 1 includes a first shell portion 14 and a second shell portion 15. The first shell portion 14 forms a heating chamber, and the second shell portion 15 forms a volute of the liquid pump 2. A liquid pump chamber 13 is formed in 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 arranged in the liquid pump inner cavity 134. The liquid inlet channel 133 extends to the opening of the end face of the second shell portion 15 to form a liquid pump inlet 131. The liquid outlet channel 135 extends to the opening of the end face of the second shell portion 15 to form a liquid pump outlet 132. It is understandable that the first shell 14 forms the liquid inlet cavity 11, the first shell 14 can be regarded as the outer shell of the heater 3, the second shell 15 can be regarded as the volute of the liquid pump 2, and the housing 1 includes the first shell 14 and the second shell 15, that is, the housing 1 integrates the volute of the liquid pump 2 and the outer shell of the heater 3, so the liquid cooling module 10 does not need to be externally connected to the integral heater 3 and the integral liquid pump 2, which simplifies the structure and reduces the volume. It is understandable that the first shell 14 and the second shell 15 can be either an integrated structure or a split structure connected by a conventional connection method.

[0047] Exemplarily, one end of the liquid pump inner cavity 134 is provided with an inner cavity inlet 136, which is connected to the liquid inlet channel 133. The arrangement of the liquid inlet channel 133 and the liquid outlet channel 135 not only meets the requirements of the integration of various components, but also facilitates the layout of the liquid pump inlet 131, thereby facilitating the connection with the load end. Exemplarily, 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 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 cavity 134 from the inner cavity inlet 136 along the liquid inlet channel 133, and then enters the liquid outlet channel 135 from the liquid pump inner cavity 134, and enters the liquid inlet chamber 11 along the liquid outlet channel 135. When the liquid inlet chamber 11 flows out, 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.

[0048] See also Figure 9-14 In other embodiments, the heater 3 and the first heat exchanger 4 are 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, the liquid inlet cavity 11 is provided with a first liquid inlet outlet 112a and a second liquid inlet outlet 112b, the inlet of the heater 3 is provided at the first liquid inlet outlet 112a, and the inlet of the first heat exchanger 4 is provided at the second liquid inlet outlet 112b. In this embodiment, the liquid pump 2, the first heat exchanger 4 and the heater 3 are integrated into the housing 1, and the first heat exchanger 4 and the heater 3 are connected in parallel, which can also reduce space occupancy.

[0049] In order to control the flow rate of the liquid inlet chamber 11 entering the heater 3 and the flow rate entering the first heat exchanger 4, the outlet of the heater 3 can be connected to a valve, such as a switch valve or a flow valve. For example, a flow valve is provided between the outlet of the heater 3 and the load end, and the flow valve is used to adjust the flow rate of the liquid flowing from the liquid inlet chamber 11 through the heater 3 to the load end, so that the liquid in the liquid inlet chamber 11 partially enters the heater 3 and partially enters the first heat exchanger 4 according to a suitable proportion, thereby achieving precise adjustment of the outlet liquid temperature, or the liquid in the liquid inlet chamber 11 does not flow into the heater 3 but enters the first heat exchanger 4. In another example, a switch valve can also be provided between the outlet of the heater 3 and the load end, and the switch valve can control the on-off of the branch of the heater 3 and the load end. It can be understood that, in the case where the 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 for the liquid temperature flowing into the load end.

[0050] In some embodiments, see Figure 12-14The liquid inlet cavity 11 is also 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 provided on the housing 1 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 pump 2, the heater 3, the first heat exchanger 4 and the valve 5 are all integrated into the housing 1, the structure is more compact, and the space occupied is smaller.

[0051] In some embodiments, the housing 1 is further formed with a liquid outlet cavity 12, the liquid outlet cavity 12 is provided with a first liquid outlet inlet 121a, a second liquid outlet inlet 121b and a liquid outlet valve inlet 121c, the outlet of the heater 3 is provided at the first liquid outlet inlet 121a, the outlet of the first heat exchanger 4 is provided at the second liquid outlet 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 set above, the liquid outlets of the first heat exchanger 4, the second heat exchanger 6, and the heater 3 are also integrated into the housing 1, which further improves the degree of integration, reduces the overall material cost and assembly cost, reduces the overall space occupancy, reduces the number of leakage points, and improves the reliability of the liquid cooling module 10.

[0052] Furthermore, 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 flow valve or a switch 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 flowing through the heater body and into the liquid outlet chamber 12 in the liquid inlet chamber 11, thereby achieving accurate adjustment of the outlet liquid temperature. Please refer to the above embodiment for the specific flow rate adjustment method of the switch valve or the flow valve, which will not be repeated here.

[0053] In some embodiments, the liquid cooling module 10 further includes a temperature detection device 91, which is disposed in the liquid outlet cavity 12. The temperature detection device 91 is used to detect the temperature of the liquid in the liquid outlet cavity 12, so as to accurately control the liquid outlet temperature of the chiller. Exemplarily, the temperature detection device 91 is a temperature sensor. By integrating the temperature detection device 91 into the housing 1, the integration level of the liquid cooling module 10 is further improved.

[0054] In some embodiments, the liquid cooling module 10 further includes a pressure detection device 92, which is disposed in the liquid outlet cavity 12. The pressure detection device 92 is used to detect the pressure of the liquid in the liquid outlet cavity 12, so as to accurately control the liquid outlet pressure of the chiller. Exemplarily, the pressure detection device 92 is a pressure sensor. By integrating the pressure detection device 92 into the housing 1, the degree of integration of the liquid cooling module 10 is further improved. Exemplarily, the temperature detection device 91 and the pressure detection device 92 are integrated, that is, a temperature and pressure integrated sensor is used, and it is disposed in the liquid outlet cavity 12.

[0055] In other embodiments, in the liquid cooling module 10, only the inlet of the device is integrated with the shell 1, such as the inlet of the first heat exchanger 4 and the valve 5 are integrated with the liquid pump 2, while the outlet of the device, such as the outlet of the first heat exchanger 4 and the second heat exchanger 6, is not integrated with the shell 1, that is, the liquid inlet from the load end is integrated, while the liquid outlet to the load end is not integrated, and is respectively sent to the load end through corresponding pipelines, thereby avoiding heat conduction between different temperatures of the inlet and outlet liquids, avoiding mutual influence between the two, and ensuring the working efficiency of the liquid cooling system.
