[0044] The embodiments of the present application disclose a liquid cooling module and a liquid cooling system, so as to reduce the space occupation, reduce the leakage points and reduce the cost.

[0045] ​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 other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application.

[0046] The liquid cooling module provided by the present application is suitable for a liquid cooling system. It can be understood that the liquid cooling system is used for temperature control, and specifically can refrigerate, and can also heat according to needs. The heating principle is similar to the refrigeration principle, and both are heat exchange 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 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 the 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. The heater is connected in series or parallel with the first heat exchanger to heat the liquid flowing therethrough. 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 refrigerate the load end, the heater can be used to heat the liquid in combination with the 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 system can be pure water, or can be added with a refrigerant.

[0047] In a specific example, referring to Figure 1 The heater 3 is connected in parallel with the first heat exchanger 4. 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, 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 be a plate exchanger. The outlet of the liquid pump 2 is also 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 be a dry cooler to cool the liquid at the outlet of the load end. The outlet of the liquid pump 2 is also 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 system operation, 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 rate connected with the corresponding device is adjusted.

[0048] 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 connected between the outlet of the first heat exchanger 4 and the inlet of the load end, and 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.

[0049] In order to simplify the structure of the above-mentioned liquid cooling system, facilitate on-site assembly, reduce space occupation, and reduce leakage points, the application provides a liquid cooling module, a liquid cooling box and a liquid cooling system, which can compactly arrange at least part of the devices in the above-mentioned liquid cooling system and thermally insulate the high-temperature region and the low-temperature region in the system, thereby reducing the volume of the module and the system on the basis of ensuring working efficiency.

[0050] In some embodiments, referring to Figure 2 The liquid cooling module provided by the application includes a shell 1, a liquid pump 2, a temperature regulator and a valve 5. The shell 1 is formed with a liquid inlet cavity 11, which is provided with a liquid inlet inlet 111 and a liquid inlet first outlet 112a. The shell 1 is the main integrated structure of the liquid cooling module, which is used to compactly arrange devices such as the liquid pump 2. It can be understood that the shell 1 can be a one-piece structure or a split structure connected by a conventional sealing method. In one example, the shell 1 is a one-piece structure, that is, it is integrally formed, which has excellent sealing performance. In another example, the shell 1 is a split structure, including a base and a shell cover, which are sealingly connected. The shape and size of the liquid inlet cavity 11 are not limited in this embodiment and can be set as needed.

[0051] The liquid pump 2 is arranged in the shell 1, and the inlet of the liquid pump 2 is used to connect with the load end. The outlet of the liquid pump 2 is communicated with the liquid inlet inlet 111. The inlet of the temperature regulator is arranged at the liquid inlet first outlet 112a, and the temperature regulator is the first heat exchanger 4 or the heater 3. It should be noted that the liquid pump 2 is arranged in the shell 1, which means that the liquid pump 2 is installed in the shell 1 and is not connected to the shell 1 by a pipeline. The inlet of the first temperature regulator is arranged at the liquid inlet first outlet 112a, that is, the inlet of the first temperature regulator is installed at the liquid inlet first outlet 112a and is not connected by a pipeline. The valve 5 is arranged in the shell 1 and communicated with the liquid inlet cavity 11, and the valve 5 is used to connect with the second heat exchanger 6 to adjust the on-off relationship between the liquid inlet cavity 11 and the second heat exchanger 6. The valve 5 is installed in the shell 1 and is not connected by a pipeline.

[0052] The outlet of the temperature regulator is used to communicate with the load end through a corresponding pipeline, and the outlet of the second heat exchanger 6 is used to communicate with the load end through a corresponding pipeline. That is, in the present application, only the inlet of the temperature regulator and the valve 5 are integrated with the liquid pump 2, and the outlet of the temperature regulator and the outlet of the second heat exchanger 6 connected with the valve 5 are not integrated in the shell 1, that is, the inlet liquid from the load end is integrated, and the outlet liquid to the load end is not integrated, and is respectively sent to the load end through a corresponding pipeline.

[0053] By using the liquid cooling module provided in the present application, the shell 1 is provided, the shell 1 is formed with the liquid inlet cavity 11, the liquid pump 2 is arranged in the shell 1, the inlet of the heater 3 or the first heat exchanger 4 is arranged in the liquid inlet cavity 11, and the valve 5 is also arranged in the liquid inlet cavity 11. The liquid pump 2 can pump the liquid of the load end to the liquid inlet cavity 11, and then into the corresponding heater 3, first heat exchanger 4, valve 5 and second heat exchanger 6 connected with the valve 5 through the liquid inlet cavity 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 load end through the corresponding pipeline, and a cycle is completed.

[0054] In summary, the liquid cooling module provided in the present application integrates the liquid pump 2 in the shell 1, and integrates at least two of the heater 3, first heat exchanger 4 and valve 5 in the shell 1. When the liquid cooling system is assembled on site, it is not necessary to install the liquid pump 2, corresponding devices and liquid inlet pipelines of the devices, thereby reducing the number of devices during the on-site assembly of the liquid cooling system, simplifying the assembly process, and reducing the overall material cost and assembly cost. The difficulty of device maintenance is reduced, the module design structure is compact, and the overall space occupation is reduced. In addition, the first heat exchanger 4 and the valve 5 or the heater 3 and the valve 5 are respectively integrated in the shell 1, and there is only one leakage point between the respective inlets and the shell 1. Compared with the connection of the liquid pump 2 through the pipeline, there is one leakage point at each end of the pipeline, so the above integrated arrangement reduces the number of leakage points and improves the reliability of the liquid cooling module. Furthermore, the liquid cooling module only integrates the inlet liquid from the load end, and does not integrate the outlet liquid to the load end, thereby avoiding the heat conduction between the inlet liquid and the outlet liquid at different temperatures, avoiding the mutual influence of the two, and thereby ensuring the working efficiency of the liquid cooling system.

[0055] In some embodiments, the outlet 51 of the valve 5 used to connect with the second heat exchanger 6 and the outlet of the temperature regulator are located at opposite ends of the shell 1, so as to be connected with the corresponding pipelines from the two ends of the shell 1. For example, the outlet 51 of the valve 5 used to connect with the second heat exchanger 6 is located at the top end of the shell 1, and the outlet 41 of the first heat exchanger 4 or the outlet of the heater 3 is located at the bottom end of the shell 1. The pipeline connected with the outlet 51 of the valve 5 and the second heat exchanger 6 can be arranged from the top end of the shell 1, and the pipeline between the outlet 41 of the first heat exchanger 4 or the outlet of the heater 3 and the load end can be arranged from the bottom end of the shell 1, thereby achieving full utilization of space and avoiding layout interference between different pipelines.

[0056] In some embodiments, the liquid inlet cavity 11 is further provided with a second liquid inlet outlet 112b, the temperature regulator is a heater 3, and the liquid cooling module further comprises a first heat exchanger 4. The inlet of the heater 3 is arranged at the first liquid inlet outlet 112a, the inlet of the first heat exchanger 4 is arranged at the second liquid inlet outlet 112b, and the outlet of the heater 3 and the outlet 41 of the first heat exchanger 4 are respectively communicated with the load end through corresponding pipelines. In this embodiment, the liquid inlets of the heater 3, the first heat exchanger 4 and the valve 5 are integrated in the shell 1, and the heater 3 and the first heat exchanger 4 form a parallel relationship. The heater 3, the first heat exchanger 4 and the valve 5 are respectively installed in the shell 1 and are not connected through pipelines, further reducing the number of devices to be installed on site of the liquid cooling system, simplifying the assembly process and reducing the leakage points.

[0057] In order to control the flow rate of the liquid inlet cavity 11 into the heater 3 and the flow rate of the liquid inlet cavity 11 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 arranged between the outlet of the heater 3 and the load end, and the flow rate of the liquid flowing from the liquid inlet cavity 11 into the load end through the heater 3 is adjusted through the flow valve, so that part of the liquid in the liquid inlet cavity 11 enters the heater 3 and part of the liquid in the liquid inlet cavity 11 enters the first heat exchanger 4, thereby realizing accurate adjustment 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 arranged between the outlet of the heater 3 and the load end, and 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 arranged, the outlet liquid temperature of the first heat exchanger 4 can also be adjusted to make the liquid flowing into the load end meet the requirements.

[0058] In some embodiments, the first liquid inlet outlet 112a and the second liquid inlet outlet 112b are arranged at two sides of the shell 1. In this way, the heater 3 and the first heat exchanger 4 are arranged at different sides of the shell 1. In one way, the heater 3 and the first heat exchanger 4 are arranged at two adjacent sides of the shell 1. In another way, the heater 3 and the first heat exchanger 4 are arranged at two opposite sides of the shell 1. As arranged above, the space is fully utilized, the overall space occupation of the liquid cooling module is reduced, thereby being conducive to reducing the overall volume of the liquid cooling system, so that the liquid cooling system can also be used in an environment with small space.

[0059] In some embodiments, the inlet of the heater 3 is connected with the liquid inlet first outlet 112a through the first joint 12. The inlet of the heater 3 is connected with the shell 1 through the first joint 12, which is convenient for operation and reliable for sealing connection. The specific model of the first joint 12 can be set according to the inlet of the heater 3, which is not limited here. It can be understood that the first joint 12 can be part of the heater 3, or a separate component provided on the heater 3 to connect with the shell 1; or the first joint 12 can be part of the shell 1, or a separate component provided on the shell 1 to connect with the heater 3. Specifically, the first joint 12 includes a male head and a female head, and the male head can be part of the heater 3 or a separate component provided on the heater 3, and the female head can be part of the shell 1 or a separate component provided on the shell 1. The male head is connected with the female head, such as clamped, to connect the heater 3 with the shell 1. In some specific examples, the first joint 12 is a quick release joint to facilitate disassembly and assembly of the liquid cooling module.

[0060] The inlet of the first heat exchanger 4 is connected with the liquid inlet second outlet 112b through the second joint 13. The specific model of the second joint 13 can be set according to the inlet of the first heat exchanger 4, which is not limited here. It can be understood that the second joint 13 can be part of the first heat exchanger 4, or a separate component provided on the first heat exchanger 4 to connect with the shell 1; or the second joint 13 can be part of the shell 1, or a separate component provided on the shell 1 to connect with the first heat exchanger 4. Specifically, the second joint 13 includes a male head and a female head, and the male head can be part of the first heat exchanger 4 or a separate component provided on the first heat exchanger 4, and the female head can be part of the shell 1 or a separate component provided on the shell 1. The male head is connected with the female head, such as clamped, to connect the first heat exchanger 4 with the shell 1. In some specific examples, the second joint 13 is a quick release joint to facilitate disassembly and assembly of the liquid cooling module. For example, the first joint 12 and the second joint 13 are of the same model to facilitate unified processing and assembly.

[0061] In some embodiments, the temperature regulator is the heater 3, the inlet of the heater 3 is arranged at the liquid inlet first outlet 112a, and the outlet of the heater 3 is connected with the inlet of the first heat exchanger 4, and the outlet of the first heat exchanger 4 is communicated with the load end through a pipeline. In this embodiment, the inlet of the heater 3 and the inlet of the valve 5 are integrated in the shell 1, and the heater 3 is connected in series with the first heat exchanger 4, and the inlet of the first heat exchanger 4 can be mounted at the outlet of the heater 3 or connected with the outlet of the heater 3 through a pipeline. When the liquid cooling system is installed on site, the liquid pump 2 and the heater 3 do not need to be assembled, and the assembly process is simplified. The heater 3 is connected in series with the first heat exchanger 4, when the heater 3 is started and the first heat exchanger 4 is not working, the liquid is heated by the heater 3 and then flows through the first heat exchanger 4 and returns to the load end; when the first heat exchanger 4 is working, the heater 3 can not be started, the liquid enters the first heat exchanger 4 after passing through the liquid inlet chamber 11 and is cooled and then returns to the load end, or the heater 3 can be controlled to work 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.

[0062] In some embodiments, the temperature regulator is the first heat exchanger 4, the inlet of the first heat exchanger 4 is arranged at the liquid inlet first outlet 112a, the outlet of the first heat exchanger 4 is connected with the inlet of the heater 3, and the outlet of the heater 3 is communicated with the load end through a pipeline. This embodiment and the above-mentioned embodiment both adopt the series connection mode of the first heat exchanger 4 and the heater 3, and the difference lies in that the inlet of the first heat exchanger 4 and the inlet of the valve 5 are integrated in the shell 1 in this embodiment. The inlet of the heater 3 can be mounted at the outlet of the first heat exchanger 4 or connected with the outlet of the first heat exchanger 4 through a pipeline. When the liquid cooling system is installed on site, the liquid pump 2 and the first heat exchanger 4 do not need to be assembled, and the assembly process is simplified.

[0063] In some embodiments, please refer to Figure 3 and Figure 4, the temperature regulator is the first heat exchanger 4, and the liquid cooling module further comprises a heating module 31, and the heating module 31 is arranged in the liquid inlet cavity 11. In this embodiment, the first heat exchanger 4 and the heater 3 are also connected in series, and the difference is that the heating module 31 is arranged in the liquid inlet cavity 11, so that the heater with a liquid flow channel is not needed to be connected, the first outlet 112a of the liquid inlet cavity 11 is connected with the inlet of the first heat exchanger 4, and then the liquid can flow into the first heat exchanger 4 after passing through the liquid inlet cavity 11. When the heating module 31 is started and the first heat exchanger 4 is not working, the liquid is heated by the heating module 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 module 31 can not be started, the liquid enters the first heat exchanger 4 after passing through the liquid inlet cavity 11 and is cooled, and then returns to the load end, or the heating module 31 can be controlled to work 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. Compared with the above-mentioned mode that the first heat exchanger 4 and the heater 3 are connected in series, the integration degree of the liquid cooling module is further improved in this embodiment, and the space occupation is smaller.

[0064] In some embodiments, referring to Figure 2 , the liquid inlet cavity 11 is further provided with a liquid inlet valve outlet 112c, the liquid inlet valve outlet 112c is used for being connected with the inlet of the second heat exchanger 6, and the valve 5 is used for controlling the opening and closing of 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 through a pipeline or the like, so that the layout of the second heat exchanger 6 is facilitated. In other embodiments, referring to Figure 4 , the liquid inlet cavity 11 is provided with a liquid inlet valve outlet 112c, the inlet of the valve 5 is arranged in 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 not connected with the shell 1 through a pipeline, but is connected with the valve 5, so that the control of the valve 5 on the connection of the second heat exchanger 6 with the liquid cooling module can also be realized.

[0065] In some embodiments, the valve 5 is a two-way valve, the inlet of the two-way valve is arranged in the liquid inlet cavity 11, and the outlet of the two-way valve is connected with the liquid inlet valve outlet 112c. When the two-way valve is opened, the liquid in the liquid inlet cavity 11 enters the two-way valve and then enters the second heat exchanger 6 through the liquid inlet valve outlet 112c. When the two-way valve is closed, the liquid inlet valve outlet 112c is disconnected with the second heat exchanger 6. In this embodiment, the two-way valve is integrated in the shell 1, and the second heat exchanger 6 and the liquid inlet valve outlet 112c of the shell 1 are connected through a pipeline or the like. In other embodiments, the inlet of the two-way valve can be connected with the liquid inlet valve outlet 112c, and the outlet of the two-way valve and the inlet of the second heat exchanger 6 can be connected through a pipeline or the like.

[0066] In some embodiments, the valve 5 is a three-way valve, an inlet of the three-way valve is connected to the liquid inlet cavity 11, and two outlets of the three-way valve are respectively connected to the liquid inlet first outlet 112a and the liquid inlet valve outlet 112c. When the liquid inlet first outlet 112a is opened and the liquid inlet valve outlet 112c is closed, the liquid in the liquid inlet cavity 11 enters the temperature regulator through the three-way valve; when the liquid inlet first outlet 112a is closed and the liquid inlet valve outlet 112c is opened, the liquid in the liquid inlet cavity 11 enters the second heat exchanger 6 through the three-way valve. In this embodiment, the three-way valve is integrated in the shell 1, the second heat exchanger 6 is connected to the liquid inlet valve outlet 112c of the shell 1 through a pipeline, and the inlet of the first temperature regulator is arranged at the liquid inlet first outlet 112a. In other embodiments, the inlet of the three-way valve can be connected to the liquid inlet valve outlet 112c, one outlet of the three-way valve is connected to the inlet of the second heat exchanger 6 through a pipeline, and the other outlet of the three-way valve is connected to the liquid inlet first outlet 112a.

[0067] In some embodiments, the liquid cooling module includes a shell 1, a liquid pump 2, a first heat exchanger 4, and a heater 3. The shell 1 is provided with a liquid inlet cavity 11, the liquid inlet cavity 11 is provided with a liquid inlet inlet 111, a liquid inlet first outlet 112a, and a liquid inlet second outlet 112b; the liquid pump 2 is arranged in the shell 1, and an outlet of the liquid pump 2 is connected to the liquid inlet inlet 111; an inlet of the first heat exchanger 4 is arranged at the liquid inlet first outlet 112a; an inlet of the heater 3 is arranged at the liquid inlet second outlet 112b; and outlets of the first heat exchanger 4 and the heater 3 are respectively connected to a load end through corresponding pipelines. In this embodiment, the liquid pump 2, the first heat exchanger 4, and the heater 3 are integrated in the shell 1, and the first heat exchanger 4 and the heater 3 are connected in parallel. The valve 5 can be integrated in the shell 1 or not, for example, the valve 5 can be connected through a pipeline. For specific structures of the liquid pump 2, the shell 1, and the first heat exchanger 4 and the heater 3, refer to the related descriptions in the above embodiments, which will not be repeated here. In this liquid cooling module, when the liquid cooling system is assembled on site, the liquid pump 2, the first heat exchanger 4, the heater 3, and the corresponding liquid inlet pipe do not need to be installed, thereby reducing the number of devices during the assembly of the liquid cooling system on site, simplifying the assembly process, and reducing the overall material cost and assembly cost. The difficulty of device maintenance is reduced, the module design structure is compact, and the overall space occupation is reduced. In addition, the first heat exchanger 4 and the heater 3 are integrated in the shell 1, and there is only one leakage point between the inlets of the first heat exchanger 4 and the heater 3 and the shell 1. Compared with the case where the first heat exchanger 4 and the heater 3 are respectively connected to the liquid pump 2 through pipelines, there is one leakage point at each end of the pipeline, so the above integrated arrangement reduces the number of leakage points and improves the reliability of the liquid cooling module. Furthermore, the liquid cooling module only integrates the liquid inlet from the load end, but does not integrate the liquid outlet to the load end, thereby avoiding heat conduction between the liquid inlet and the liquid outlet at different temperatures and avoiding mutual influence between the two, thereby ensuring the working efficiency of the liquid cooling system.

[0068] In some embodiments, the housing 1 further forms a liquid pump cavity, which is provided with a module inlet 14 and a liquid pump cavity outlet, and the inlet of the liquid pump 2 is arranged at the liquid pump cavity outlet, and the module inlet 14 is connected to the load end. In this embodiment, the liquid pump cavity is arranged at the inlet of the liquid pump 2, and the module inlet 14 is connected to the load end through a pipeline. Under the action of the liquid pump 2, the liquid from the load end enters the liquid pump cavity through the module inlet 14, and then enters the liquid pump 2 through the liquid pump cavity outlet. When the liquid pump 2 is connected through a pipeline, the flow resistance is large. In this embodiment, the liquid pump cavity is arranged in front of the inlet of the liquid pump 2, and the flow area of the liquid pump cavity is larger than that of the pipeline connected to the inlet of the liquid pump 2. Compared with the pipeline, the flow resistance is significantly reduced, 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 arranged as needed, which is not limited here. When the volume of the liquid pump cavity is small, bubbles are not easy to form in it, so as to prevent bubbles from entering the liquid pump 2. In other embodiments, the inlet of the liquid pump 2 can also be connected to the load end through a pipeline.

[0069] In some embodiments, the liquid cooling module further comprises an expansion tank 7 arranged in the liquid pump cavity. It can be understood that the shape of the expansion tank 7 can be selected as needed, such as a tank or a box. By integrating the expansion tank 7 into the housing 1, the integration level of the liquid cooling module is further improved.

[0070] Based on the liquid cooling module provided in the above embodiments, please refer to Figure 5 The application also provides a liquid cooling system, which comprises any one of the liquid cooling modules 10 in the above embodiments. Since the liquid cooling system adopts the liquid cooling module 10 in the above embodiments, the beneficial effects of the liquid cooling system are referred to the above embodiments.

[0071] In some embodiments, the liquid cooling system further comprises a temperature detection device 91 arranged in a pipeline connected to the outlet of the temperature regulator. The temperature detection device 91 is used to detect the temperature of the liquid, so as to accurately control the outlet temperature of the system. For example, the temperature detection device 91 is a temperature sensor.

[0072] In some embodiments, the liquid cooling module further comprises a pressure detection device arranged in a pipeline connected to the outlet of the temperature regulator. The pressure detection device is used to detect the pressure of the liquid, so as to accurately control the outlet pressure of the system. For example, the pressure detection device is a pressure sensor. For example, the temperature detection device 91 and the pressure detection device are integrated, that is, a temperature and pressure integrated sensor is used. The outlet is not integrated into the housing 1, but is connected through a pipeline respectively, and the corresponding temperature detection device 91 and pressure detection device are arranged in the outlet pipeline, and the detection results are more accurate and reliable, and are not affected by the inlet temperature.
