Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and more particularly to a cooling device and a data center. Background Technology

[0002] Cooling equipment (e.g., cooling distribution units, CDUs) is used to transfer external cooling energy to equipment (e.g., servers) to achieve cooling. The cooling equipment and the equipment to be cooled are typically connected via closed-loop piping to allow the cooling medium to circulate. During the delivery of cooling equipment, the piping within the cooling equipment, the connecting piping, and the piping inside the equipment to be cooled generally need to be flushed separately before being connected to the grid. However, due to the lack of a power source, additional flushing pumps and filters are required during the flushing process. The addition and removal of these components makes the flushing process redundant and complex, wasting significant labor and time costs. Therefore, optimizing the flushing structure has become a pressing technical problem. Summary of the Invention

[0003] This application provides a cooling device and data center to reduce additional facilities and lower flushing costs during the flushing process.

[0004] To achieve the above objectives, the embodiments of this application adopt the following technical solutions: A first aspect of this application provides a cooling device comprising a heat exchanger, a secondary inlet pipe, and a secondary outlet pipe, wherein the outlet of the secondary inlet pipe and the inlet of the secondary outlet pipe are both connected to the heat exchanger; the cooling device further comprises a pump body, a filter, and two first multi-way valves, wherein one of the secondary inlet pipe and the secondary outlet pipe is provided with the pump body and the two first multi-way valves, and the pump body is located between the two first multi-way valves; the filter is connected to one of the two first multi-way valves; two ports of each first multi-way valve are used to connect to the secondary inlet pipe or the secondary outlet pipe; the inlet of the secondary inlet pipe and the outlet of the secondary outlet pipe are used to connect to the equipment to be cooled; the pump body is used to drive a first coolant to flow within the heat exchanger, the secondary inlet pipe, the secondary outlet pipe, and the equipment to be cooled; or, the other port of each first multi-way valve is used to connect to the equipment to be cooled, and the pump body is used to drive a cleaning fluid to flow within a portion of the secondary inlet pipe or the secondary outlet pipe between the equipment to be cooled, the filter, and the two first multi-way valves.

[0005] In this cooling device, one side of the heat exchanger is connected to the secondary side inlet pipe, and the other side is connected to the secondary side outlet pipe. A pump body is installed in either the secondary side inlet pipe or the secondary side outlet pipe. During use, the ends of the secondary side inlet pipe and the secondary side outlet pipe that are away from the heat exchanger are connected to the external equipment to be cooled. This creates a complete liquid flow channel, allowing the first cooling medium to form a hot-cold alternating cycle between the heat exchanger and the equipment to be cooled through the secondary side inlet pipe and the secondary side outlet pipe, thereby achieving effective cooling of the equipment to be cooled.

[0006] Secondly, by installing two first multi-way valves on one of the secondary side inlet pipes or the secondary side outlet pipes, and positioning the pump body between the two first multi-way valves, in another usage process, the equipment to be cooled can be connected to the secondary side inlet pipe or the secondary side outlet pipe located between the two first multi-way valves through the two first multi-way valves. This can create another liquid flow channel. Applying this architecture to the rinsing process of the equipment to be cooled can reuse the pump body of the cooling equipment to provide power for the cleaning fluid, so that the cleaning fluid can repeatedly rinse the equipment to be cooled. Meanwhile, the filter can intercept impurities in the rinsing process, effectively improving the rinsing effect.

[0007] Compared to flushing the equipment to be cooled by adding an external drive pump and filter, this cooling device can reuse the internally installed pump body. That is, the pump body can not only drive the first cooling medium to play a role in the cooling process of the equipment to be cooled, but also drive the cleaning fluid to play a role in the flushing process of the equipment to be cooled. This architecture can reduce the number of additional parts in the flushing process of the equipment to be cooled, reduce the number of on-site parts, and reduce the installation time of flushing parts, thereby improving the efficiency of flushing the equipment to be cooled and reducing costs.

[0008] In one implementation, the cooling device has a working mode and a cleaning mode. In the working mode, the inlet of the secondary side liquid inlet pipe and the outlet of the secondary side liquid outlet pipe are used to connect to the equipment to be cooled, and the pump body is used to drive the first coolant to flow in the heat exchanger, the secondary side liquid inlet pipe, the secondary side liquid outlet pipe and the equipment to be cooled. In the cleaning mode, the other port of each first multi-way valve is used to connect to the equipment to be cooled, and the pump body is used to drive the cleaning fluid to flow in the equipment to be cooled, the filter and part of the secondary side liquid inlet pipe or the secondary side liquid outlet pipe between the two first multi-way valves.

[0009] The two different liquid flow channel architectures mentioned above are implemented in the working mode and cleaning mode of this implementation, respectively. In other words, the two different usage processes of the pump body mentioned above are the working mode and cleaning mode of this implementation. This setting enables the cooling equipment to have two different modes, which serve the different needs (cooling or rinsing) of the equipment to be cooled. On the one hand, it can make the functions of the cooling equipment more complete and comprehensive. On the other hand, it can eliminate the need to switch between different service equipment under different needs of the equipment to be cooled, thereby improving the user experience.

[0010] In one implementation, the cooling device further includes a second multi-way valve. The secondary side inlet pipe is equipped with a pump body and two first multi-way valves. One port of the second multi-way valve is connected to the outlet of the secondary side outlet pipe, and the other port of the second multi-way valve is connected to the other port of one of the first multi-way valves. One of the first multi-way valves is located on the side of the pump body away from the inlet of the secondary side inlet pipe, and the other port of the second multi-way valve is used to connect to the equipment to be cooled. Alternatively, the secondary side outlet pipe is equipped with a pump body and two first multi-way valves. One port of the second multi-way valve is connected to the inlet of the secondary side inlet pipe, and the other port of the second multi-way valve is connected to the other port of one of the first multi-way valves. One of the first multi-way valves is located on the side of the pump body away from the outlet of the secondary side outlet pipe, and the other port of the second multi-way valve is used to connect to the equipment to be cooled.

[0011] In this implementation, a second multi-way valve is installed at the outlet of the secondary side liquid outlet pipe. This second multi-way valve is used to connect the equipment to be cooled to the first multi-way valve on the side of the secondary side liquid outlet pipe or pump body away from the inlet of the secondary side liquid inlet pipe. Alternatively, a second multi-way valve is installed at the inlet of the secondary side liquid inlet pipe. This second multi-way valve is used to connect the equipment to be cooled to the first multi-way valve on the side of the secondary side liquid inlet pipe or pump body away from the outlet of the secondary side liquid outlet pipe. In this way, by changing the valve core of the second multi-way valve, the inlet or outlet of the equipment to be cooled can be switched between two modes. On the one hand, this reduces the number of times the joints between the equipment to be cooled and the cooling equipment are switched during the switching between working mode and cleaning mode, reducing the steps and time in the mode switching process. On the other hand, it also reduces the number of interfaces on the surface of the cooling equipment, reducing the difficulty of processing and assembly, and reducing the risk of external debris entering the interior of the cooling equipment through the interfaces on the surface of the cooling equipment.

[0012] In one implementation, the cooling device further includes a third multi-way valve. The secondary side inlet pipe is equipped with a pump body and two first multi-way valves. One port of the third multi-way valve is connected to the inlet of the secondary side inlet pipe, and the other port of the third multi-way valve is connected to the other port of one of the first multi-way valves. One of the first multi-way valves is located on the side of the pump body facing the inlet of the secondary side inlet pipe, and the other port of the third multi-way valve is used to connect to the equipment to be cooled. Alternatively, the secondary side outlet pipe is equipped with a pump body and two first multi-way valves. One port of the third multi-way valve is connected to the outlet of the secondary side outlet pipe, and the other port of the third multi-way valve is connected to the other port of one of the first multi-way valves. One of the first multi-way valves is located on the side of the pump body facing the outlet of the secondary side outlet pipe, and the other port of the third multi-way valve is used to connect to the equipment to be cooled.

[0013] In this implementation, a third multi-way valve is installed at the inlet of the secondary side liquid inlet pipe. The second multi-way valve is used to connect the equipment to be cooled with the first multi-way valve on the side of the secondary side liquid inlet pipe or pump body facing the inlet of the secondary side liquid inlet pipe. Alternatively, a third multi-way valve is installed at the outlet of the secondary side liquid outlet pipe. The third multi-way valve is used to connect the equipment to be cooled with the first multi-way valve on the side of the secondary side liquid outlet pipe or pump body facing the outlet of the secondary side liquid outlet pipe. In this way, by changing the valve core of the third multi-way valve, the inlet or outlet of the equipment to be cooled can be switched between two modes. On the one hand, it can reduce the number of joint switching between the equipment to be cooled and the cooling equipment during the switching between working mode and cleaning mode, and reduce the steps and time in the mode switching process. On the other hand, it can reduce the number of interfaces on the surface of the cooling equipment, reduce the difficulty of processing and assembly, and reduce the risk of external debris entering the interior of the cooling equipment through the interfaces on the surface of the cooling equipment.

[0014] In one implementation, the cooling device further includes two cleaning branch pipes, each of which is connected to a secondary side liquid inlet pipe or a secondary side liquid outlet pipe via a corresponding first multi-way valve. The two cleaning branch pipes are also used to connect to the equipment to be cooled.

[0015] In this implementation, by setting two cleaning branch pipes, the length of the ports of the two first multi-way valves used to connect to the equipment to be cooled is extended. This allows the operator to freely deploy the positions of the two first multi-way valves according to the internal spatial layout of the cooling equipment, which effectively reduces the difficulty of the internal structural layout of the cooling equipment and improves the flexibility of the layout design.

[0016] In one implementation, the cooling device further includes two valves, one of the two cleaning branch pipes is equipped with a filter and the two valves, and the filter is located between the two valves.

[0017] In this implementation, by placing the filter in one of the two cleaning branch pipes, the first cooling medium can be prevented from flowing through the filter during operation. This reduces unnecessary flow resistance of the first cooling medium and unnecessary frictional wear on the filter, thereby improving the filter's service life. Secondly, the two valves located on both sides of the filter can cut off the cleaning fluid upstream and downstream of the filter during filter maintenance. This structure reduces the difficulty of filter maintenance and improves convenience.

[0018] In one implementation, the heat exchanger has multiple adjacent heat exchange channels, the outlet of the secondary side liquid inlet pipe and the inlet of the secondary side liquid outlet pipe are both connected to one of the multiple heat exchange channels, and the other heat exchange channel is used to connect to refrigeration equipment.

[0019] In this implementation, one of the multiple heat exchange channels, together with the secondary side liquid inlet pipe, the secondary side liquid outlet pipe, and the heat dissipation equipment, forms the circulation channel of the first cooling medium in the working mode. Another heat exchange channel is used to connect to the refrigeration equipment (such as a chiller or cooling tower) located outside the computer room. In this way, during operation, the refrigeration equipment can provide uninterrupted cooling to the other heat exchange channel, and the first cooling medium in the adjacent heat exchange channel can achieve the purpose of cooling through heat exchange between the two adjacent heat exchange channels.

[0020] In one implementation, the cooling device further includes a primary side inlet pipe and a primary side outlet pipe. The outlet of the primary side inlet pipe and the inlet of the primary side outlet pipe are both connected to another heat exchange channel. The inlet of the primary side inlet pipe and the outlet of the primary side outlet pipe are both used to connect to a refrigeration device. The refrigeration device is used to cool the second coolant and drive the second coolant to flow in the primary side inlet pipe, the primary side outlet pipe and the other heat exchange channel.

[0021] In this implementation, a high-temperature first cooling medium from the equipment to be cooled enters one heat exchange channel of the heat exchanger through the secondary side inlet pipe, while a low-temperature second cooling medium from the refrigeration equipment enters another heat exchange channel of the heat exchanger through the primary side inlet pipe. The high-temperature first cooling medium and the low-temperature second cooling medium are indirectly in contact through the intermediate wall of the two heat exchange channels, thereby achieving the exchange of heat and cold. After heat exchange, a low-temperature first cooling medium and a high-temperature second cooling medium are formed. The low-temperature first cooling medium flows along the secondary side outlet pipe and flows to the equipment to be cooled, thereby cooling the equipment. The high-temperature second cooling medium flows along the primary side outlet pipe and flows to the refrigeration equipment, and then enters the next refrigeration cycle.

[0022] In one implementation, the cooling device further includes at least one detection element, which is connected to at least one of the secondary side liquid inlet pipe, the secondary side liquid outlet pipe, the primary side liquid inlet pipe, or the primary side liquid outlet pipe. The detection element is used to detect at least one parameter among pH, conductivity, and turbidity.

[0023] In this implementation, by setting up multiple detection devices, the status of the first cooling medium, the second cooling medium, or the cleaning fluid can be monitored online in real time. Taking the first cooling medium as an example, during long-term use, the first cooling medium inevitably produces problems such as bacterial colonies or impurities carried from the pipe wall. If these problems are not resolved in time, they can easily affect the operation of the heat exchanger and the equipment to be cooled. By setting up the aforementioned multiple detection devices in the secondary side inlet pipe or the secondary side outlet pipe, the pH, conductivity, and turbidity of the first cooling medium during the flow process can be obtained in real time. If there are many bacterial colonies or impurities in the first cooling medium, the operator can easily judge the current health status of the first cooling medium by the changes in pH, conductivity, and turbidity and their comparison with reference values, thereby facilitating the operator to adjust and improve the first cooling medium in a timely manner. In addition, by matching and comparing real-time pH, conductivity, and turbidity with historical data, it is possible to predict the changing trend of the first cooling medium. This allows operators to identify potential deterioration of the first cooling medium in advance and provides sufficient time for adjustment, thereby improving the stability and reliability of the cooling equipment during use. The second cooling medium and cleaning fluid can also be monitored in the same way, which will not be elaborated here.

[0024] In addition, the secondary side inlet and outlet pipes need to be flushed with cleaning fluid during delivery. If the cleaning fluid is not drained in time after flushing, it may affect the operation of the cooling equipment in working mode. In this implementation, if one of the secondary side inlet or outlet pipes is connected to the above-mentioned multiple detection devices, it is possible to identify whether there is cleaning fluid in the secondary side inlet or outlet pipe by monitoring the change in conductivity and the operating status of the pump. This will promptly remind the operator to drain the cleaning fluid or start the pump to run at low load to maintain the flow of liquid in the secondary side inlet or outlet pipe and reduce the risk of colony formation.

[0025] In one implementation, a detection element is connected to a secondary side inlet pipe or a secondary side outlet pipe, and the detection element is located between two first multi-way valves.

[0026] In this implementation, during operation, the first cooling medium flows through the secondary inlet or outlet pipe between the two first multi-way valves. During this flow, the sensors detect the state of the first cooling medium. During cleaning, the cleaning fluid flows through the secondary inlet or outlet pipe between the two first multi-way valves. During this flow, the sensors detect the state of the cleaning fluid. In other words, by placing these sensors between the two first multi-way valves, they achieve a "multi-purpose" effect, simultaneously meeting the detection needs of both the first cooling medium and the cleaning fluid. This reduces the number of sensors in the piping system, lowering the cost of the cooling equipment, and effectively reduces the number of components, improving the utilization of space within the cooling equipment. Furthermore, during cleaning, monitoring the status of these sensors and the pump body allows for monitoring of the cleaning duration and effect, making the cleaning process data traceable and reducing the difficulty of on-site delivery.

[0027] In one implementation, the cooling device further includes at least one liquid storage tank, which is connected to at least one of a secondary side inlet pipe, a secondary side outlet pipe, a primary side inlet pipe, or a primary side outlet pipe, and is used to store the liquid medicine.

[0028] In this implementation, the storage tank can replenish the first or second cooling medium with a chemical solution, which can be a corrosion inhibitor or a bactericide. The corrosion inhibitor can improve the corrosion of the inner wall of the pipe and components such as the pump body, while the bactericide can improve the bacterial colony problem in the first or second cooling medium.

[0029] In one implementation, the liquid storage tank is connected to a secondary side inlet pipe or a secondary side outlet pipe, and the outlet of the liquid storage tank is located between two first multi-way valves.

[0030] In this implementation, the liquid storage tank is configured to provide liquid for the first cooling medium in working mode and to provide liquid for the cleaning fluid in cleaning mode. In other words, the liquid storage tank can function in both modes, taking into account the needs of both the first cooling medium and the cleaning fluid, thus achieving the effect of "one unit for multiple uses".

[0031] A second aspect of this application provides a data center comprising a server room, a plurality of devices to be cooled, and a cooling device according to any of the foregoing implementations, wherein the plurality of devices to be cooled and the cooling device are both located within the server room, and the cooling device is used to cool the plurality of devices to be cooled.

[0032] During operation, the cooling equipment delivers a low-temperature first cooling medium to each device to be cooled. The first cooling medium heats up within each device to become a high-temperature first cooling medium. The high-temperature first cooling medium flows back to the cooling equipment through the connecting pipes within each device to enter the next cycle. The heat within the device is carried away by the flowing first cooling medium, and the coldness within the first cooling medium is evenly diffused into the interior of the device by the air, thus achieving effective cooling of the device. Furthermore, since this data center includes the cooling equipment in any of the aforementioned implementations, it also possesses the technical effects of the cooling equipment in any of the aforementioned implementations. Detailed technical effects can be found in the preceding text and will not be repeated here. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the embodiments of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0038] In the accompanying drawings of this application embodiment, lower-level specific physical structures such as valves and pipelines are represented by leader lines; higher-level components or enlarged areas such as components and parts are represented by leader lines with solid arrows; auxiliary lines are represented by dashed lines; reference directions are represented by straight lines with arrows; and overall components are represented by horizontal superscript characters or curly braces.

[0039] A data center (1000) is an infrastructure used for centralized storage, processing, and management of data information. It centralizes computing devices (such as servers), storage devices (such as hard drives), network devices (such as switches), and power supply devices (such as uninterruptible power supply cabinets). These devices are generally located in the server room (1100) of the data center (1000). During operation, these devices generate a large amount of heat. Excessive heat accumulation can lead to excessively high ambient temperatures in the server room (1100), which can affect the operation of devices such as servers. Therefore, a data center (1000) generally needs to be equipped with at least one (or more) cooling devices (1300). The cooling devices (1300) are used to cool down the heat source devices (1210) that need cooling (such as servers). It can be understood that the cooling devices (1300) and the heat source devices (1210) can have a one-to-one or one-to-many connection relationship, which can be adapted according to the actual situation.

[0040] In order to transfer the cooling output of the cooling equipment 1300 to these heat source devices 1210, a connecting pipe 1220 needs to be laid between the cooling equipment 1300 and these heat source devices 1210. Figure 1 The structure of a data center 1000 provided in an embodiment of this application is illustrated by way of example, wherein the solid line "1220" represents the connecting pipe 1220 for transporting cold energy, and the dashed line "1220" represents the connecting pipe 1220 for transporting heat energy. (See reference...) Figure 1 The data center 1000 has multiple heat source devices 1210 arranged in its server room 1100, and a cooling device 1300 configured therein. The cooling device 1300 is connected to these heat source devices 1210 through connecting pipes 1220. Cold and heat are exchanged between these heat source devices 1210 and the cooling device 1300 through the connecting pipes 1220. The connecting pipes 1220 include a main pipe and branch pipes to facilitate the connection between the cooling device 1300 and these heat source devices 1210. In another embodiment of this application, multiple connecting pipes 1220 are provided, and multiple heat source devices 1210 and cooling devices 1300 are connected one-to-one through multiple connecting pipes 1220.

[0041] For ease of explanation, the heat source devices 1210 and the connecting pipes 1220 between these heat source devices 1210 and the cooling device 1300 will be collectively referred to as the cooling device 1200. That is, the cooling device 1200 includes the heat source devices 1210 and the connecting pipes 1220. One heat source device 1210 and the part of the connecting pipes 1220 between it and the cooling device 1300 can be understood as one cooling device 1200. Alternatively, multiple heat source devices 1210 and all the connecting pipes 1220 between these heat source devices 1210 and the cooling device 1300 can be understood as one cooling device 1200.

[0042] Continue reading Figure 1 During operation, the cooling device 1300 delivers a low-temperature first cooling medium (e.g., deionized water) to each device 1200 to be cooled. The first cooling medium heats up within each device 1200 to form a high-temperature first cooling medium. This high-temperature first cooling medium flows back to the cooling device 1300 via the connecting pipe 1220 within each device 1200 to enter the next cycle. It should be noted that in this application, "high temperature" and "low temperature" are only used to indicate the relative temperature state of the first cooling medium (and the second cooling medium described below). For example, the first cooling medium cooled by the cooling device 1300 is in a "low temperature" state relative to the first cooling medium that has not been cooled, while the first cooling medium heated by the device 1200 is understood to be in a "high temperature" state relative to the first cooling medium cooled by the cooling device 1300. In other words, high temperature and low temperature are not used as specific limitations on the first cooling medium, i.e., they do not specifically refer to the temperature of the first cooling medium reaching a certain threshold.

[0043] Within each device 1200 to be cooled, a low-temperature first cooling medium flows through a cold plate 1230 (the cold plate 1230 is a heat dissipation structure with channels inside the device 1200, and its surface is usually provided with multiple heat dissipation fins) and exchanges heat with the air inside the device 1200. The heat inside the device 1200 is carried away by the flowing first cooling medium, and the coldness in the first cooling medium is evenly diffused into the interior of the device 1200 by the air. That is, the first cooling medium and the device 1200 are cooled through indirect contact to achieve cooling. In other embodiments of this application, an immersion cooling method can also be used, for example, immersing at least a portion (partial or all) of the heating element in the device 1200 in the first coolant, or the heating element itself has a flow channel structure that allows the first cooling medium to flow through. That is, the first cooling medium and the device 1200 can also be cooled through direct contact.

[0044] Before connecting the cooling device 1300 and the device to be cooled 1200, it is generally necessary to flush the pipes in the cooling device 1300, the connecting pipes 1220 in the device to be cooled 1200, and the interior of the heat source device 1210 separately. Only after these flushes meet the required standards can they be connected to the grid. However, during the flushing process of the connecting pipes 1220 and the heat source device 1210, due to the lack of a power source, additional flushing pumps and filters are required. The addition and removal of these additional facilities makes the flushing process redundant and complicated, wasting significant labor and economic costs. Therefore, this application provides a cooling device 1300 to reduce the need for additional facilities and lower flushing costs during the flushing process.

[0045] Figure 2 An exemplary illustration shows the internal piping connection structure of a first cooling device 1300 provided in this application embodiment, wherein region A represents the primary side, region B represents the secondary side, and the curved dashed line between region B and the device to be cooled 1200 represents the omitted portion of the pipe. The meaning of the same portions in other accompanying drawings will not be explained further. See also... Figure 2 The cooling device 1300 includes a heat exchanger 100, a secondary side liquid inlet pipe 210, and a secondary side liquid outlet pipe 220. The outlet of the secondary side liquid inlet pipe 210 and the inlet of the secondary side liquid outlet pipe 220 are both connected to the heat exchanger 100. That is, the inlet of the heat exchanger 100 is connected to the secondary side liquid inlet pipe 210, and the outlet of the heat exchanger 100 is connected to the secondary side liquid outlet pipe 220. The first coolant flows from the secondary side liquid inlet pipe 210 to the heat exchanger 100, and then flows from the heat exchanger 100 to the secondary side liquid outlet pipe 220.

[0046] In one embodiment of this application, the cooling device 1300 further includes a pump body 230, see further details. Figure 2 The pump body 230 is disposed on the secondary side inlet pipe 210. In one example of the embodiments of this application, the pump body 230 is disposed at the inlet or outlet of the secondary side inlet pipe 210, that is, disposed between the secondary side inlet pipe 210 and other components (such as heat exchanger 100 or cooling device 1200). In another example of the embodiments of this application, the pump body 230 is disposed in the middle part of the secondary side inlet pipe 210. In this case, it is equivalent to the pump body 230 dividing the secondary side inlet pipe 210 into two parts, which are located on both sides of the pump body 230.

[0047] Figure 3 An exemplary illustration shows the internal piping connection structure of a second cooling device 1300 provided in an embodiment of this application. (See reference...) Figure 3In another embodiment of this application, the pump body 230 is disposed on the secondary side outlet pipe 220. In one example of the embodiments of this application, the pump body 230 is disposed at the inlet or outlet of the secondary side outlet pipe 220, that is, disposed between the secondary side outlet pipe 220 and other components (such as heat exchanger 100 or cooling device 1200). In another example of the embodiments of this application, the pump body 230 is disposed in the middle part of the secondary side outlet pipe 220. In this case, it is equivalent to the pump body 230 dividing the secondary side outlet pipe 220 into two parts, which are located on both sides of the pump body 230 respectively.

[0048] The cooling unit 1300 also includes two first multi-way valves 250, see further. Figure 2 With the pump body 230 located on the secondary inlet pipe 210, two first multi-way valves 250 are also located on the secondary inlet pipe 210, and the two first multi-way valves 250 are located on both sides of the pump body 230. Two ports of each first multi-way valve 250 are used to connect to the secondary inlet pipe 210; continue reading Figure 3 When the pump body 230 is installed on the secondary side outlet pipe 220, two first multi-way valves 250 are also installed on the secondary side outlet pipe 220, and the two first multi-way valves 250 are located on both sides of the pump body 230. Two ports of each first multi-way valve 250 are used to connect to the secondary side outlet pipe 220.

[0049] The cooling device 1300 also includes a filter 240, which is connected to one of the two first multi-way valves 250, see further. Figure 2 In one embodiment of this application, when two first multi-way valves 250 are disposed in the secondary side inlet pipe 210, the filter 240 is disposed in the portion of the secondary side inlet pipe 210 between the two first multi-way valves 250; see also... Figure 3 When two first multi-way valves 250 are installed in the secondary side outlet pipe 220, the filter 240 is installed in the portion of the secondary side outlet pipe 220 between the two first multi-way valves 250.

[0050] See Figure 2 and Figure 3In one operation, the inlet of the secondary side liquid inlet pipe 210 and the outlet of the secondary side liquid outlet pipe 220 are used to connect to the device to be cooled 1200. The low-temperature first cooling medium is generated at the heat exchanger 100, then enters the secondary side liquid outlet pipe 220 and flows along the secondary side liquid outlet pipe 220, and finally leaves the cooling device 1300 from the outlet of the secondary side liquid outlet pipe 220 and enters the device to be cooled 1200. The high-temperature first cooling medium from the device to be cooled 1200 enters the secondary side liquid inlet pipe 210 through the inlet of the secondary side liquid inlet pipe 210 and flows along the secondary side liquid inlet pipe 210 to the heat exchanger 100, where it is cooled and then forms the low-temperature first cooling medium for the next cycle. That is, in this process, the pump body 230 drives the first cooling medium to circulate in the secondary side liquid inlet pipe 210, the heat exchanger 100, the secondary side liquid outlet pipe 220 and the device to be cooled 1200.

[0051] Figure 4 An exemplary illustration shows the internal piping connection structure of a third cooling device 1300 provided in an embodiment of this application. Figure 4 and Figure 2 Correspondingly, the pump body 230 and the two first multi-way valves 250 are both located on the secondary side inlet pipe 210; Figure 5 An exemplary illustration shows the internal piping connection structure of the fourth cooling device 1300 provided in this application embodiment. Figure 5 and Figure 3 Correspondingly, the pump body 230 and the two first multi-way valves 250 are both located on the secondary side outlet pipe 220.

[0052] See Figure 4 and Figure 5 In another usage scenario, the other port of one of the two first multi-way valves 250 located on the pump body 230 outlet side (distinguished from the aforementioned "two ports") is used to connect to the inlet of the device to be cooled 1200, and the other port of the other first multi-way valve 250 located on the pump body 230 inlet side (distinguished from the aforementioned "two ports") is used to connect to the outlet of the device to be cooled 1200. It should be noted that inside the cooling device 1300, the "other port" of the two first multi-way valves 250 can be extended to the surface of the cooling device 1300 by extending pipes to facilitate communication with the device to be cooled 1200. The two first multi-way valves 250 can also be set against the surface of the cooling device 1300 and the "other port" can be directly connected to the connector on the surface of the cooling device 1300, or the "other port" of the two first multi-way valves 250 can be directly exposed on the outside of the cooling device 1300 (the outer surface of the cooling device 1300 has an opening).

[0053] In this case, the liquid flowing within the secondary system is the cleaning fluid. (See [reference needed]) Figure 4 If the pump body 230 and the two first multi-way valves 250 are located in the secondary side inlet pipe 210, the cleaning fluid is driven by the pump body 230 and flows to the portion of the secondary side inlet pipe 210 between the two first multi-way valves 250; see reference Figure 5 If the pump body 230 and the two first multi-way valves 250 are installed in the secondary side outlet pipe 220, the cleaning fluid is driven by the pump body 230 and flows to the secondary side outlet pipe 220 between the two first multi-way valves 250.

[0054] Then, the cleaning fluid flows from the other port of the first multi-way valve 250 located on the outlet side of the pump body 230 to the cooling device 1200. After rinsing once inside the cooling device 1200, it enters from the other port of the first multi-way valve 250 located on the inlet side of the pump body 230 and flows back to the pump body 230, finally entering the next cycle. During each cleaning process, the cleaning fluid is filtered by the filter 240 to intercept impurities washed down during the rinsing process. It should be noted that the filter 240 can be located between the two first multi-way valves 250 mentioned in the aforementioned embodiment, or it can be located on the pipeline connecting either of the two first multi-way valves 250 to the cooling device 1200.

[0055] In summary, in the cooling device 1300 provided in this application embodiment, one side of the heat exchanger 100 is connected to the secondary side liquid inlet pipe 210, and the other side is connected to the secondary side liquid outlet pipe 220. A pump body 230 is provided on either the secondary side liquid inlet pipe 210 or the secondary side liquid outlet pipe 220. During use, the ends of the secondary side liquid inlet pipe 210 and the secondary side liquid outlet pipe 220 that are away from the heat exchanger 100 are connected to the external cooling device 1200. This creates a complete liquid flow channel, allowing the first cooling medium to form a hot-cold alternating cycle between the heat exchanger 100 and the cooling device 1200 through the secondary side liquid inlet pipe 210 and the secondary side liquid outlet pipe 220, thereby achieving effective cooling of the cooling device 1200.

[0056] Secondly, by setting two first multi-way valves 250 on one of the secondary side inlet pipe 210 or the secondary side outlet pipe 220, and placing the pump body 230 between the two first multi-way valves 250, in another usage process, the device to be cooled 1200 can be connected to the secondary side inlet pipe 210 or the secondary side outlet pipe 220 located between the two first multi-way valves 250 through the two first multi-way valves 250, thus constructing another liquid flow channel. Applying this architecture to the rinsing process of the device to be cooled 1200, the pump body 230 of the cooling device 1300 can be reused to provide power for the cleaning fluid, so that the cleaning fluid can repeatedly rinse the device to be cooled 1200. Meanwhile, the filter 240 can intercept impurities that fall off during the rinsing process, effectively improving the rinsing effect.

[0057] Compared to flushing the device 1200 to be cooled by adding an external drive pump and filter, the cooling device 1300 provided in this application embodiment can reuse the pump body 230 already installed inside the cooling device 1300. That is, the pump body 230 can not only drive the first cooling medium to play a role in the cooling process of the device 1200 to be cooled, but also drive the cleaning fluid to play a role in the flushing process of the device 1200 to be cooled. This architecture can reduce the additional components in the flushing process of the device 1200 to be cooled, reduce the number of on-site components, and reduce the installation time of the flushing components, which can improve the efficiency of flushing the device 1200 to be cooled and reduce costs.

[0058] In one embodiment of this application, the cooling device 1300 has a working mode and a cleaning mode, see reference. Figure 2 and Figure 3 In the working mode, the inlet of the secondary side liquid inlet pipe 210 and the outlet of the secondary side liquid outlet pipe 220 are used to connect to the device to be cooled 1200. The pump body 230 is used to drive the first cooling medium to flow in the heat exchanger 100, the secondary side liquid inlet pipe 210, the secondary side liquid outlet pipe 220 and the device to be cooled 1200. For a detailed description, please refer to the previous text. In the cleaning mode, the other port of each first multi-way valve 250 (distinct from the ports other than the aforementioned "two ports") is used to connect to the device to be cooled 1200. The pump body 230 is used to drive the cleaning fluid to flow in the device to be cooled 1200, the filter 240 and part of the secondary side liquid inlet pipe 210 or the secondary side liquid outlet pipe 220 between the two first multi-way valves 250.

[0059] In other words, the two different liquid flow channel architectures in the aforementioned embodiments are implemented in the working mode and cleaning mode of this application embodiment, respectively. In other words, the two different usage processes of the aforementioned pump body 230 are the working mode and cleaning mode of this application embodiment. This setting enables the cooling device 1300 to have two different modes, serving the different needs (cooling or rinsing) of the device 1200 to be cooled. On the one hand, it can make the functions of the cooling device 1300 more comprehensive and complete; on the other hand, it can eliminate the need to switch between different service devices under different needs of the device 1200 to be cooled, thereby improving the user experience.

[0060] In one embodiment of this application, the cooling device 1300 further includes a second multi-way valve 260. Figure 6 An exemplary illustration shows the internal piping connection structure of the fifth cooling device 1300 provided in this application embodiment, see reference. Figure 6 The pump body 230 and two first multi-way valves 250 are disposed on the secondary side inlet pipe 210, and the second multi-way valve 260 is located at the outlet of the secondary side outlet pipe 220. One port of the second multi-way valve 260 is connected to the outlet of the secondary side outlet pipe 220, and the other port of the second multi-way valve 260 is connected to the other port of one of the two first multi-way valves 250 (different from the ports other than the aforementioned "two ports"). The first multi-way valve 250 is located on the side of the pump body 230 away from the inlet of the secondary side inlet pipe 210, that is, the first multi-way valve 250 is located on the outlet side of the pump body 230. The other port of the second multi-way valve 260 is used to connect to the device 1200 to be cooled.

[0061] In the working mode, the second multi-way valve 260 connects the cooling device 1200 and the secondary side liquid outlet pipe 220. The low-temperature first cooling medium starts from the heat exchanger 100, flows through the secondary side liquid outlet pipe 220 and the second multi-way valve 260, and then flows into the cooling device 1200. After being heated in the cooling device 1200, the high-temperature first cooling medium enters the cooling device 1300 through the inlet of the secondary side liquid inlet pipe 210, and flows to the heat exchanger 100 under the drive of the pump body 230 for the next refrigeration cycle. The two first multi-way valves 250 are used to connect the secondary side liquid inlet pipe 210.

[0062] In cleaning mode, the second multi-way valve 260 connects the device to be cooled 1200 and the first multi-way valve 250 connected to the second multi-way valve 260. The two first multi-way valves 250 cut off the secondary side inlet pipe 210. The cleaning fluid is driven by the pump body 230 and flows from the first multi-way valve 250 on the outlet side of the pump body 230 to the second multi-way valve 260. After passing through the second multi-way valve 260, it flows into the device to be cooled 1200 to rinse the device to be cooled. After rinsing once, the cleaning fluid flows from the first multi-way valve 250 on the inlet side of the pump body 230 into the secondary side inlet pipe 210 between the two first multi-way valves 250, and enters the next cycle under the drive of the pump body 230.

[0063] Understandable Figure 6 The solid black line between the intermediate cooling device 1200 and the secondary liquid inlet pipe 210 indicates the connection structure in the working mode. Figure 6 The black dotted line between the cooling device 1200 and the secondary liquid inlet pipe 210 indicates the connection structure under cleaning mode.

[0064] That is, the outlet of the cooling device 1200 switches between the inlet of the secondary side liquid inlet pipe 210 and the first multi-way valve 250 on the inlet side of the pump body 230, depending on the working mode and the cleaning mode. The inlet of the cooling device 1200 is connected to the second multi-way valve 260 in both the working mode and the cleaning mode. The inlet of the cooling device 1200 is connected to the outlet of the secondary side liquid outlet pipe 220 or the first multi-way valve 250 on the outlet side of the pump body 230 by changing the valve core of the second multi-way valve 260.

[0065] In another example of this application embodiment, the pump body 230 and two first multi-way valves 250 are disposed on the secondary side outlet pipe 220, and the second multi-way valve 260 is located at the inlet of the secondary side inlet pipe 210. Figure 7 An exemplary illustration shows the internal piping connection structure of the sixth cooling device 1300 provided in this application embodiment. (See reference...) Figure 7 In this configuration, one port of the second multi-way valve 260 is connected to the inlet of the secondary side liquid inlet pipe 210, and the other port of the second multi-way valve 260 is connected to the other port of one of the two first multi-way valves 250 (distinguished from the ports other than the aforementioned "two ports"). The first multi-way valve 250 is located on the side of the pump body 230 away from the outlet of the secondary side liquid outlet pipe 220, that is, the first multi-way valve 250 is located on the inlet side of the pump body 230. The other port of the second multi-way valve 260 is used to connect to the cooling device 1200.

[0066] In the working mode, the second multi-way valve 260 connects the cooling device 1200 and the secondary side liquid inlet pipe 210. The low-temperature first cooling medium starts from the heat exchanger 100 and flows into the cooling device 1200 along the secondary side liquid outlet pipe 220. After being heated in the cooling device 1200, the high-temperature first cooling medium enters the secondary side liquid inlet pipe 210 through the second multi-way valve 260 and flows along the secondary side liquid inlet to the heat exchanger 100 for the next cycle. The two first multi-way valves 250 are used to connect the secondary side liquid outlet pipe 220.

[0067] In cleaning mode, the second multi-way valve 260 connects the device to be cooled 1200 and the first multi-way valve 250 connected to the second multi-way valve 260. The two first multi-way valves 250 cut off the secondary side liquid outlet pipe 220. The cleaning fluid is driven by the pump body 230 and flows from the first multi-way valve 250 on the outlet side of the pump body 230 to the device to be cooled 1200. After flowing into the device to be cooled 1200, it flushes the device to be cooled. After one flush, the cleaning fluid enters the cooling device 1300 from the second multi-way valve 260 and flows to the first multi-way valve 250 on the inlet side of the pump body 230. Under the drive of the pump body 230, it enters the next cycle.

[0068] Understandable Figure 7 The solid black line between the intermediate cooling device 1200 and the secondary side liquid outlet pipe 220 indicates the connection structure in the working mode. Figure 7 The black dotted line between the cooling device 1200 and the secondary side liquid outlet pipe 220 indicates the connection structure under cleaning mode.

[0069] That is, depending on the working mode and the cleaning mode, the inlet of the cooling device 1200 switches between the outlet of the secondary side liquid outlet pipe 220 and the first multi-way valve 250 on the outlet side of the pump body 230. The outlet of the cooling device 1200 is connected to the second multi-way valve 260 in both the working mode and the cleaning mode. The outlet of the cooling device 1200 is connected to the inlet of the secondary side liquid inlet pipe 210 or the first multi-way valve 250 on the inlet side of the pump body 230 by changing the valve core of the second multi-way valve 260.

[0070] In summary, in the cooling device 1300 provided in this application embodiment, by setting a second multi-way valve 260 at the outlet of the secondary side liquid outlet pipe 220, the second multi-way valve 260 is used to connect the device to be cooled 1200 with the first multi-way valve 250 at the outlet side of the secondary side liquid outlet pipe 220 or the pump body 230. Alternatively, by setting a second multi-way valve 260 at the inlet of the secondary side liquid inlet pipe 210, the second multi-way valve 260 is used to connect the device to be cooled 1200 with the first multi-way valve 250 at the inlet side of the secondary side liquid inlet pipe 210 or the pump body 230. In this way, on the one hand, the number of joint switching between the device to be cooled 1200 and the cooling device 1300 can be reduced during the switching between working mode and cleaning mode, and the steps and time in the mode switching process can be reduced. On the other hand, the number of interfaces on the surface of the cooling device 1300 can be reduced, the difficulty of processing and assembly can be reduced, and the risk of external debris entering the interior of the cooling device 1300 through the interfaces on the surface of the cooling device 1300 can be reduced.

[0071] In one embodiment of this application, the cooling device 1300 further includes a third multi-way valve 270. Figure 8 An exemplary illustration shows the internal piping connection structure of the seventh cooling device 1300 provided in this application embodiment. (See reference...) Figure 8 The pump body 230 and two first multi-way valves 250 are disposed on the secondary side inlet pipe 210. The third multi-way valve 270 is located at the inlet of the secondary side inlet pipe 210. One port of the third multi-way valve 270 is connected to the inlet of the secondary side inlet pipe 210, and the other port of the third multi-way valve 270 is connected to the other port of one of the two first multi-way valves 250 (different from the ports other than the aforementioned "two ports"). The first multi-way valve 250 is located on the side of the pump body 230 facing the inlet of the secondary side inlet pipe 210, that is, the first multi-way valve 250 is located on the inlet side of the pump body 230. The other port of the third multi-way valve 270 is used to connect to the device 1200 to be cooled.

[0072] In the working mode, the third multi-way valve 270 connects the cooling device 1200 and the secondary side liquid inlet pipe 210. The low-temperature first cooling medium starts from the heat exchanger 100, flows through the secondary side liquid outlet pipe 220 and then flows into the cooling device 1200. After being heated in the cooling device 1200, the high-temperature first cooling medium enters the secondary side liquid inlet pipe 210 through the third multi-way valve 270 and flows to the heat exchanger 100 under the drive of the pump body 230 for the next refrigeration cycle. Among them, the two first multi-way valves 250 are used to connect the secondary side liquid inlet pipe 210.

[0073] In cleaning mode, the third multi-way valve 270 connects the device to be cooled 1200 and the first multi-way valve 250 connected to the third multi-way valve 270. The two first multi-way valves 250 cut off the secondary side inlet pipe 210. The cleaning fluid is driven by the pump body 230 and flows from the first multi-way valve 250 on the outlet side of the pump body 230 to the device to be cooled 1200 to rinse the device to be cooled. After rinsing once, the cleaning fluid flows from the third multi-way valve 270 to the first multi-way valve 250 on the inlet side of the pump body 230, and then enters the secondary side inlet pipe 210 between the two first multi-way valves 250, and enters the next cycle under the drive of the pump body 230.

[0074] Understandable Figure 8 The solid black line between the intermediate cooling device 1200 and the secondary liquid inlet pipe 210 indicates the connection structure in the working mode. Figure 8 The black dotted line between the cooling device 1200 and the secondary liquid inlet pipe 210 indicates the connection structure under cleaning mode.

[0075] That is, depending on the working mode and the cleaning mode, the inlet of the cooling device 1200 switches between the outlet of the secondary side liquid outlet pipe 220 and the first multi-way valve 250 on the outlet side of the pump body 230. The outlet of the cooling device 1200 is connected to the third multi-way valve 270 in both the working mode and the cleaning mode. The outlet of the cooling device 1200 is connected to the outlet of the secondary side liquid outlet pipe 220 or the first multi-way valve 250 on the inlet side of the pump body 230 by changing the valve core of the third multi-way valve 270.

[0076] In another example of this application embodiment, the pump body 230 and two first multi-way valves 250 are disposed on the secondary side outlet pipe 220, and the third multi-way valve 270 is located at the outlet of the secondary side outlet pipe 220. Figure 9 An exemplary illustration shows the internal piping connection structure of the eighth cooling device 1300 provided in this application embodiment, see reference. Figure 9 In this configuration, one port of the third multi-way valve 270 is connected to the outlet of the secondary side liquid outlet pipe 220, and the other port of the third multi-way valve 270 is connected to the other port of one of the two first multi-way valves 250 (distinct from the ports other than the aforementioned "two ports"). The first multi-way valve 250 is located on the side of the pump body 230 facing the outlet of the secondary side liquid outlet pipe 220, that is, the first multi-way valve 250 is located on the outlet side of the pump body 230. Another port of the third multi-way valve 270 is used to connect to the cooling device 1200.

[0077] In the working mode, the third multi-way valve 270 connects the cooling device 1200 and the secondary side liquid outlet pipe 220. The low-temperature first cooling medium starts from the heat exchanger 100, flows along the secondary side liquid outlet pipe 220, and flows into the cooling device 1200 from the third multi-way valve 270. After being heated in the cooling device 1200, the high-temperature first cooling medium enters the cooling device 1300 from the secondary side liquid inlet pipe 210, and flows along the secondary side liquid inlet pipe 210 to the heat exchanger 100 for the next cycle under the drive of the pump body 230. Among them, the two first multi-way valves 250 are used to connect the secondary side liquid outlet pipe 220.

[0078] In cleaning mode, the third multi-way valve 270 connects the device to be cooled 1200 and the first multi-way valve 250 connected to the third multi-way valve 270. The two first multi-way valves 250 cut off the secondary side outlet pipe 220. The cleaning fluid is driven by the pump body 230 and flows from the first multi-way valve 250 on the outlet side of the pump body 230 to the third multi-way valve 270. It enters the device to be cooled 1200 from the third multi-way valve 270 and then rinses the device to be cooled 1200. After rinsing once, the cleaning fluid enters the secondary side outlet pipe 220 between the two first multi-way valves 250 from the first multi-way valve 250 on the inlet side of the pump body 230 and enters the next cycle under the drive of the pump body 230.

[0079] Understandable Figure 9 The solid black line between the intermediate cooling device 1200 and the secondary liquid inlet pipe 210 indicates the connection structure in the working mode. Figure 9 The black dotted line between the cooling device 1200 and the first multi-way valve 250 on the inlet side of the pump body 230 indicates the connection structure in the cleaning mode.

[0080] That is, the outlet of the cooling device 1200 switches between the inlet of the secondary side liquid inlet pipe 210 and the first multi-way valve 250 on the inlet side of the pump body 230, depending on the working mode and the cleaning mode. The inlet of the cooling device 1200 is connected to the third multi-way valve 270 in both the working mode and the cleaning mode. The inlet of the cooling device 1200 is connected to the outlet of the secondary side liquid outlet pipe 220 or the first multi-way valve 250 on the outlet side of the pump body 230 by changing the valve core of the third multi-way valve 270.

[0081] In summary, in the cooling device 1300 provided in this application embodiment, by setting a third multi-way valve 270 at the outlet of the secondary side liquid outlet pipe 220, the third multi-way valve 270 is used to connect the device to be cooled 1200 with the first multi-way valve 250 at the outlet side of the secondary side liquid outlet pipe 220 or the pump body 230. Alternatively, by setting a third multi-way valve 270 at the inlet of the secondary side liquid inlet pipe 210, the third multi-way valve 270 is used to connect the device to be cooled 1200 with the first multi-way valve 250 at the inlet side of the secondary side liquid inlet pipe 210 or the pump body 230. In this way, on the one hand, the number of times the connector between the device to be cooled 1200 and the cooling device 1300 is switched during the switching between the working mode and the cleaning mode can be reduced, and the steps and time in the mode switching process can be reduced. On the other hand, the number of interfaces on the surface of the cooling device 1300 can be reduced, the difficulty of processing and assembly can be reduced, and the risk of external debris entering the interior of the cooling device 1300 through the interfaces on the surface of the cooling device 1300 can be reduced.

[0082] In one embodiment of this application, the cooling device 1300 includes both a second multi-way valve 260 and a third multi-way valve 270. The pump body 230 and two first multi-way valves 250 are disposed on the secondary side inlet pipe 210. The second multi-way valve 260 is located at the outlet of the secondary side outlet pipe 220, and the third multi-way valve 270 is located at the inlet of the secondary side inlet pipe 210. Figure 10 An exemplary illustration shows the internal piping connection structure of the ninth cooling device 1300 provided in this application embodiment. (See reference...) Figure 10 In this configuration, one port of the second multi-way valve 260 is connected to the outlet of the secondary side liquid outlet pipe 220, and the other port of the second multi-way valve 260 is connected to the other port of one of the two first multi-way valves 250 (distinct from the ports other than the aforementioned "two ports"). This first multi-way valve 250 is located on the side of the pump body 230 away from the inlet of the secondary side liquid inlet pipe 210, that is, on the outlet side of the pump body 230. The remaining port of the second multi-way valve 260 is used to connect to the device 120 to be cooled. 0; One port of the third multi-way valve 270 is connected to the inlet of the secondary side liquid inlet pipe 210, and the other port of the third multi-way valve 270 is connected to the other port of one of the two first multi-way valves 250 (different from the ports other than the aforementioned "two ports"). The first multi-way valve 250 is located on the side of the pump body 230 facing the inlet of the secondary side liquid inlet pipe 210, that is, the first multi-way valve 250 is located on the inlet side of the pump body 230. Another port of the third multi-way valve 270 is used to connect to the cooling device 1200.

[0083] In the working mode, the second multi-way valve 260 connects the cooling device 1200 to the secondary side liquid outlet pipe 220, and the third multi-way valve 270 connects the cooling device 1200 to the secondary side liquid inlet pipe 210. The low-temperature first cooling medium starts from the heat exchanger 100, flows through the secondary side liquid outlet pipe 220 and the second multi-way valve 260, and then flows into the cooling device 1200. After being heated in the cooling device 1200, the high-temperature first cooling medium enters the secondary side liquid inlet pipe 210 through the third multi-way valve 270, and flows to the heat exchanger 100 under the drive of the pump body 230 for the next refrigeration cycle. Among them, the two first multi-way valves 250 are used to connect the secondary side liquid inlet pipe 210.

[0084] In cleaning mode, the second multi-way valve 260 connects the device to be cooled 1200 and the first multi-way valve 250 connected to the second multi-way valve 260, and the third multi-way valve 270 connects the device to be cooled 1200 and the first multi-way valve 250 connected to the third multi-way valve 270. The two first multi-way valves 250 cut off the secondary side inlet pipe 210. The cleaning fluid is driven by the pump body 230 and flows from the first multi-way valve 250 on the outlet side of the pump body 230 to the second multi-way valve 260. After passing through the second multi-way valve 260, it flows into the device to be cooled 1200 to rinse the device to be cooled 1200. After rinsing once, the cleaning fluid flows from the third multi-way valve 270 to the first multi-way valve 250 on the inlet side of the pump body 230, and then enters the part of the secondary side inlet pipe 210 between the two first multi-way valves 250, and enters the next cycle under the drive of the pump body 230.

[0085] In other words, the inlet of the cooling device is connected to the second multi-way valve 260 in both working and cleaning modes. The inlet of the cooling device 1200 and the outlet of the secondary side liquid outlet pipe 220 or the first multi-way valve 250 on the pump body 230 outlet side are connected by the valve core change of the second multi-way valve 260. The outlet of the cooling device 1200 is connected to the third multi-way valve 270 in both working and cleaning modes. The outlet of the cooling device 1200 and the inlet of the secondary side liquid inlet pipe 210 or the first multi-way valve 250 on the pump body 230 in only the valve core change of the third multi-way valve 270 are connected by the valve core change of the third multi-way valve 270.

[0086] In another example of this application embodiment, the pump body 230 and two first multi-way valves 250 are disposed on the secondary side outlet pipe 220, the second multi-way valve 260 is located at the inlet of the secondary side inlet pipe 210, and the third multi-way valve 270 is located at the outlet of the secondary side outlet pipe 220. Figure 11 An exemplary illustration shows the internal piping connection structure of the tenth cooling device 1300 provided in this application embodiment, see reference. Figure 11In this configuration, one port of the second multi-way valve 260 is connected to the inlet of the secondary side inlet pipe 210, and the other port of the second multi-way valve 260 is connected to the other port of one of the two first multi-way valves 250 (distinct from the ports other than the aforementioned "two ports"). This first multi-way valve 250 is located on the side of the pump body 230 away from the outlet of the secondary side outlet pipe 220, that is, on the inlet side of the pump body 230. The remaining port of the second multi-way valve 260 is used to connect to the device 120 to be cooled. 0; One port of the third multi-way valve 270 is connected to the outlet of the secondary side liquid outlet pipe 220, and the other port of the third multi-way valve 270 is connected to the other port of one of the two first multi-way valves 250 (different from the ports other than the aforementioned "two ports"). The first multi-way valve 250 is located on the side of the pump body 230 facing the outlet of the secondary side liquid outlet pipe 220, that is, the first multi-way valve 250 is located on the outlet side of the pump body 230. Another port of the third multi-way valve 270 is used to connect to the cooling device 1200.

[0087] In the working mode, the second multi-way valve 260 connects the cooling device 1200 to the secondary side liquid inlet pipe 210, and the third multi-way valve 270 connects the cooling device 1200 to the secondary side liquid outlet pipe 220. The low-temperature first cooling medium starts from the heat exchanger 100, flows along the secondary side liquid outlet pipe 220, and flows into the cooling device 1200 from the third multi-way valve 270. After being heated in the cooling device 1200, the high-temperature first cooling medium enters the secondary side liquid inlet pipe 210 through the second multi-way valve 260, and flows along the secondary side liquid inlet pipe 210 to the heat exchanger 100 for the next cycle. Among them, the two first multi-way valves 250 are used to connect the secondary side liquid outlet pipe 220.

[0088] In cleaning mode, the second multi-way valve 260 connects the device to be cooled 1200 and the first multi-way valve 250 connected to the second multi-way valve 260, and the third multi-way valve 270 connects the device to be cooled 1200 and the first multi-way valve 250 connected to the third multi-way valve 270. The two first multi-way valves 250 cut off the secondary side liquid outlet pipe 220. The cleaning fluid is driven by the pump body 230 and flows from the first multi-way valve 250 on the outlet side of the pump body 230 to the third multi-way valve 270, and enters the device to be cooled 1200 from the third multi-way valve 270. After flowing into the device to be cooled 1200, it flushes the device to be cooled. After one flush, the cleaning fluid enters the cooling device 1300 from the second multi-way valve 260 and flows to the first multi-way valve 250 on the inlet side of the pump body 230. Driven by the pump body 230, it enters the next cycle.

[0089] In other words, the inlet of the cooling equipment is connected to the third multi-way valve 270 in both working and cleaning modes. The inlet of the cooling equipment 1200 and the outlet of the secondary side liquid outlet pipe 220 or the first multi-way valve 250 on the pump body 230 outlet side are connected by the valve core change of the third multi-way valve 270. The outlet of the cooling equipment 1200 is connected to the second multi-way valve 260 in both working and cleaning modes. The outlet of the cooling equipment 1200 and the inlet of the secondary side liquid inlet pipe 210 or the first multi-way valve 250 on the pump body 230 in only the valve core change of the second multi-way valve 260 are connected by the valve core change of the second multi-way valve 260.

[0090] In summary, in the cooling device 1300 provided in this application embodiment, a second multi-way valve 260 is provided at the outlet of the secondary side liquid outlet pipe 220 to connect the device 1200 to be cooled with the first multi-way valve 250 at the outlet side of the secondary side liquid outlet pipe 220 or the pump body 230; a third multi-way valve 270 is provided at the inlet of the secondary side liquid inlet pipe 210 to connect the device 1200 to be cooled with the first multi-way valve 250 at the inlet side of the secondary side liquid inlet pipe 210 or the pump body 230; or, a second multi-way valve 260 is provided at the inlet of the secondary side liquid inlet pipe 210 to connect the device 1200 to be cooled with the first multi-way valve 250 at the inlet side of the secondary side liquid inlet pipe 210. The first multi-way valve 250 on the inlet side of the pump body 230 is connected to the first multi-way valve 250 on the outlet side of the secondary side liquid outlet pipe 220 by setting a third multi-way valve 270. The third multi-way valve 270 is used to connect the cooling device 1200 to the first multi-way valve 250 on the outlet side of the secondary side liquid outlet pipe 220 or the pump body 230. In this way, on the one hand, the number of joint switching between the cooling device 1200 and the cooling device 1300 can be reduced during the switching between working mode and cleaning mode, and the steps and time in the mode switching process can be reduced; on the other hand, the number of interfaces on the surface of the cooling device 1300 can be reduced, the difficulty of processing and assembly can be reduced, and the risk of external debris entering the interior of the cooling device 1300 through the interfaces on the surface of the cooling device 1300 can be reduced.

[0091] In one embodiment of this application, the cooling device 1300 further includes two cleaning branch pipes 280, see reference. Figure 4 With two first multi-way valves 250 installed on the secondary side inlet pipe 210, each of the two cleaning branch pipes 280 is connected to the secondary inlet pipe through a corresponding first multi-way valve 250; see reference Figure 5 With two first multi-way valves 250 installed on the secondary side outlet pipe 220, each of the two cleaning branch pipes 280 is connected to the secondary side outlet pipe 220 through a corresponding first multi-way valve 250; see reference Figure 6 and Figure 7With the second multi-way valve 260 installed, one of the two cleaning branch pipes 280 is used to connect the device to be cooled 1200 and one of the first multi-way valves 250, and the other of the two cleaning branch pipes 280 is used to connect the second multi-way valve 260 and the other first multi-way valve 250; see reference Figure 8 In connection with 9, with the third multi-way valve 270 provided, one of the two cleaning branch pipes 280 is used to connect the device to be cooled 1200 and one of the first multi-way valves 250, and the other of the two cleaning branch pipes 280 is used to connect the third multi-way valve 270 and the other first multi-way valve 250; see reference Figure 10 and Figure 11 When both a second multi-way valve 260 and a third multi-way valve 270 are provided, one of the two cleaning branch pipes 280 is used to connect the second multi-way valve 260 and one of the first multi-way valves 250, and the other of the two cleaning branch pipes 280 is used to connect the third multi-way valve 270 and the other first multi-way valve 250.

[0092] That is, the two cleaning branch pipes 280 are pipes inside the cooling equipment 1300, used to connect the two first multi-way valves 250 and the equipment to be cooled 1200 in the cleaning mode. In the cleaning mode, the pump body 230 drives the cleaning fluid to flow through the two cleaning branch pipes 280, the equipment to be cooled 1200 and part of the secondary side inlet pipe 210 or part of the secondary side outlet pipe 220 between the two first multi-way valves 250.

[0093] In the cooling device 1300 provided in this embodiment, the spatial deployment of the two first multi-way valves 250 is facilitated by providing two cleaning branch pipes 280. For example, without the cleaning branch pipes 280, the second multi-way valve 260, and the third multi-way valve 270, the two first multi-way valves 250 need to be installed close to the side wall of the cooling device 1300 so that the ports of the two first multi-way valves 250 used to connect to the device 1200 to be cooled can directly align with the connectors on the surface of the device 1200 to be cooled. Alternatively, if the second multi-way valve 260 or the third multi-way valve 270 is provided, and there are no two cleaning branch pipes 280, the two first multi-way valves 250 may need to be installed close to the side wall of the cooling device 1300 so that the ports of the two first multi-way valves 250 used to connect to the device 1200 to be cooled can directly align with the connectors on the surface of the device 1200. The placement of the first multi-way valves 250 against the side wall of the cooling device 1300 may also require placement against the second multi-way valve 260 or the third multi-way valve 270, which limits the possible placement of the two first multi-way valves 250. In this embodiment, by setting two cleaning branch pipes 280, the length of the ports of the two first multi-way valves 250 used to connect to the second multi-way valve 260, the third multi-way valve 270, or the surface connector of the cooling device 1300 is extended. This allows the operator to freely deploy the positions of the two first multi-way valves 250 according to the internal spatial layout of the cooling device 1300, which effectively reduces the difficulty of the internal structural layout of the cooling device 1300 and improves the flexibility of the layout design.

[0094] In one embodiment of this application, the cooling device 1300 further includes two valves 290. Figure 12 An exemplary illustration shows the internal piping connection structure of the eleventh cooling device 1300 provided in this application embodiment, see reference. Figure 12 Two valves 290 are located on both sides of the filter 240, and the two valves 290 and the filter 240 are disposed on one of the two cleaning branch pipes 280. In one example of the embodiments of this application, the two valves 290 and the filter 240 can be disposed near the first multi-way valve 250 or near the device to be cooled 1200, that is, the two valves 290 and the filter 240 can be disposed at the end of the cleaning branch pipe 280. In another example of the embodiments of this application, the two valves 290 and the filter 240 can also be disposed in the middle of the cleaning branch pipe 280. In this case, it is equivalent to the two valves 290 and the filter 240 dividing the cleaning branch pipe 280 into multiple sub-parts.

[0095] By placing the filter 240 in one of the two cleaning branch pipes 280, the first cooling medium can be prevented from flowing through the filter 240 during operation. This reduces unnecessary flow resistance of the first cooling medium and unnecessary frictional wear of the filter 240, thus extending its service life. Furthermore, the two valves 290 located on both sides of the filter 240 can cut off the cleaning fluid upstream and downstream of the filter 240 during maintenance. This structure reduces the difficulty of maintaining the filter 240 and improves convenience.

[0096] In one embodiment of this application, the heat exchanger 100 has a plurality of adjacent heat exchange channels 110. Figure 13 An exemplary illustration shows the internal piping connection structure of the twelfth cooling device 1300 provided in this application embodiment. Figure 14 yes Figure 13 See the enlarged view of part C in the middle. Figure 13 and Figure 14 The outlet of the secondary side liquid inlet pipe 210 and the inlet of the secondary side liquid outlet pipe 220 are connected to one of the multiple heat exchange channels 110. That is, the heat exchange channel 110, the secondary side liquid inlet pipe 210, the secondary side liquid outlet pipe 220 and the heat dissipation equipment form the circulation channel of the first cooling medium in the working mode. Another heat exchange channel 110 in the multiple heat exchange channels is used to connect to the refrigeration equipment 1400 (e.g., a chiller or a cooling tower) located outside the machine room 1100. During operation, the refrigeration equipment 1400 can provide uninterrupted cooling to the heat exchange channel 110, and the first cooling medium in the adjacent heat exchange channel 110 can achieve the purpose of cooling through heat exchange between the two adjacent heat exchange channels 110.

[0097] In other embodiments of this application, the cooling device 1300 can also cool the first cooling medium inside it by means of air cooling. For example, a fan is installed on the outside of the cooling device 1300, and the fan drives the air to flow, thereby cooling the first cooling medium inside the cooling device 1300.

[0098] Continue reading Figure 13 In one embodiment of this application, the cooling device 1300 further includes a primary-side liquid inlet pipe 310 and a primary-side liquid outlet pipe 320. The outlet of the primary-side liquid inlet pipe 310 and the inlet of the primary-side liquid outlet pipe 320 are both connected to another heat exchange channel 110 used in the aforementioned embodiment for connection with the refrigeration device 1400. The inlet of the primary-side liquid inlet pipe 310 and the outlet of the primary-side liquid outlet pipe 320 are both used to connect the refrigeration device 1400. That is, the primary-side liquid inlet pipe 310 and the primary-side liquid outlet pipe 320 are located between the refrigeration device 1400 and the heat exchanger 100, and are used to connect the refrigeration device 1400 and the heat exchanger 100. The refrigeration device 1400 is used to cool the second cooling medium (e.g., water) and drive the second cooling medium to circulate within the refrigeration device 1400, the primary-side liquid inlet pipe 310, the primary-side liquid outlet pipe 320, and the other heat exchange channel 110 of the heat exchanger 100.

[0099] During operation, the high-temperature first cooling medium from the device to be cooled 1200 enters one heat exchange channel 110 of the heat exchanger 100 through the secondary side inlet pipe 210, and the low-temperature second cooling medium from the refrigeration device 1400 enters another heat exchange channel 110 of the heat exchanger 100 through the primary side inlet pipe 310. The high-temperature first cooling medium and the low-temperature second cooling medium are indirectly in contact through the intermediate wall of the two heat exchange channels 110, thereby realizing the exchange of heat and cold. After heat exchange, the low-temperature first cooling medium and the high-temperature second cooling medium are formed. The low-temperature first cooling medium flows along the secondary side outlet pipe 220 and flows to the device to be cooled 1200, thereby cooling the device to be cooled 1200. The high-temperature second cooling medium flows along the primary side outlet pipe 320 and flows to the refrigeration device 1400, and then enters the next refrigeration cycle.

[0100] Continue reading Figure 13 In one embodiment of this application, the cooling device 1300 further includes at least one detection element 400, and at least one of the secondary side liquid inlet pipe 210, the secondary side liquid outlet pipe 220, the primary side liquid inlet pipe 310 and the primary side liquid outlet pipe 320 is connected to the detection element 400. The detection element 400 is used to detect at least one parameter among pH, conductivity and turbidity.

[0101] In one example of an embodiment of this application, multiple detection elements 400 are provided, one detection element 400 is used to detect pH, another detection element 400 is used to detect conductivity, and yet another detection element 400 is used to detect turbidity. All of these detection elements 400 are connected to the secondary side inlet pipe 210. In another example of an embodiment of this application, multiple detection elements 400 are provided, one detection element 400 is used to detect pH, another detection element 400 is used to detect conductivity, and yet another detection element 400 is used to detect turbidity. All of these detection elements 400 are connected to the secondary side outlet pipe 220. In yet another example of an embodiment of this application, multiple detection elements 400 are provided, one detection element 400 is used to detect pH, another detection element 400 is used to detect conductivity, and yet another detection element 400 is used to detect turbidity. All of these detection elements 400 are connected to the primary side inlet pipe 31. 0; In another example of the embodiments of this application, multiple detection elements 400 are provided, one detection element 400 is used to detect pH, another detection element 400 is used to detect conductivity, and yet another detection element 400 is used to detect turbidity. These detection elements 400 are all connected to the primary side outlet pipe 320; In yet another example of the embodiments of this application, multiple detection elements 400 are provided, some of which are used to detect pH, another part of which are used to detect conductivity, and yet another part of which are used to detect turbidity. Some of these detection elements 400 that can detect pH, conductivity, and turbidity are connected to the primary side inlet pipe 310 or the primary side outlet pipe 320, and other parts of these detection elements 400 that can detect pH, conductivity, and turbidity are connected to the secondary side inlet pipe 210 or the secondary side outlet pipe 220.

[0102] By setting multiple detection elements 400, the status of the first cooling medium, the second cooling medium, or the cleaning fluid can be monitored online in real time. Taking the first cooling medium as an example, during long-term use, it is inevitable that bacterial colonies or impurities carried from the pipe walls will be generated. If these problems are not resolved in time, they can easily affect the operation of the heat exchanger 100 and the equipment to be cooled 1200. By setting the aforementioned multiple detection elements 400 in the secondary side inlet pipe 210 or the secondary side outlet pipe 220, the pH, conductivity, and turbidity of the first cooling medium during its flow can be obtained in real time. If there are many bacterial colonies or impurities in the first cooling medium, the operator can determine the cause based on the pH. Changes in alkalinity, conductivity, and turbidity, along with comparisons to reference values, make it relatively easy to determine the current health status of the primary cooling medium. This allows operators to adjust and improve the primary cooling medium in a timely manner. Furthermore, by matching and comparing real-time pH, conductivity, and turbidity with historical data, it is possible to predict the changing trend of the primary cooling medium. This allows operators to identify potential deterioration of the primary cooling medium in advance and provides sufficient time for adjustment, thereby improving the stability and reliability of the cooling equipment 1300 during operation. The secondary cooling medium and cleaning fluid can also be monitored in the same way, which will not be elaborated upon here.

[0103] Additionally, it is understood that the secondary side inlet pipe 210 and the secondary side outlet pipe 220 need to be flushed with cleaning fluid during delivery. If the cleaning fluid is discharged in time after flushing, it may affect the operation of the cooling equipment 1300 in working mode. In this embodiment, if one of the secondary side inlet pipe 210 or the secondary side outlet pipe 220 is connected to the above-mentioned multiple detection devices 400, it is possible to identify whether there is cleaning fluid in the secondary side inlet pipe 210 or the secondary side outlet pipe 220 by monitoring the change in conductivity and the operating status of the pump body 230. This will also remind the operator to drain the cleaning fluid in time or start the pump body 230 to operate at low load to maintain the flow of liquid in the secondary side inlet pipe 210 or the secondary side outlet pipe 220.

[0104] Continue reading Figure 13 In one embodiment of this application, when the pump body 230 and two first multi-way valves 250 are disposed on the secondary side inlet pipe 210, the secondary side inlet pipe 210 is connected to the aforementioned detection element 400, and these detection elements 400 are located between the two first multi-way valves 250; or, see [link to relevant documentation]. Figure 11 When the pump body 230 and the two first multi-way valves 250 are provided on the secondary side outlet pipe 220, the secondary side outlet pipe 220 is connected to the aforementioned detection element 400, and these detection elements 400 are located between the two first multi-way valves 250.

[0105] With this configuration, in the working mode, the first cooling medium flows through the secondary side inlet pipe 210 or the secondary side outlet pipe 220 between the two first multi-way valves 250. During the flow of the first cooling medium through this part of the pipe, the detection elements 400 can detect the state of the first cooling medium. In the cleaning mode, the cleaning fluid flows through the secondary side inlet pipe 210 or the secondary side outlet pipe 220 between the two first multi-way valves 250. During the flow of the cleaning fluid through this part of the pipe, the detection elements 400 can detect the state of the cleaning fluid. In other words, by placing these detection elements 400 between the two first multi-way valves 250, these detection elements 400 can achieve a "multi-purpose" effect, taking into account the detection needs of both the first cooling medium and the cleaning fluid. This reduces the number of detection elements 400 in the pipeline system, lowering the cost of the cooling equipment 1300. On the other hand, it effectively reduces the number of components in the cooling equipment 1300, improving the utilization rate of the internal space of the cooling equipment 1300. In addition, in cleaning mode, by monitoring the status of these detection components 400 and the pump body 230, the cleaning time and cleaning effect can be monitored, making the process data traceable and reducing the difficulty of on-site delivery.

[0106] Continue reading Figure 13 In one embodiment of this application, the cooling device 1300 further includes at least one liquid storage tank 500. In one example of this application embodiment, the liquid storage tank 500 is connected to the secondary side inlet pipe 210; in another example of this application embodiment, the liquid storage tank 500 is connected to the secondary side outlet pipe 220; in yet another example of this application embodiment, the liquid storage tank 500 is connected to the primary side inlet pipe 310; in yet another example of this application embodiment, the liquid storage tank 500 is connected to the primary side outlet pipe 320. The liquid storage tank 500 is used to store the liquid medicine. The liquid storage tank 500 can actively replenish the first cooling medium or the second cooling medium with the liquid medicine through an external drive pump or a built-in drive pump. The liquid medicine can be a corrosion inhibitor or a bactericide, etc. The corrosion inhibitor can improve the corrosion problem of the inner wall of the pipe and the pump body 230 and other components; the bactericide can improve the problem of bacterial colonies in the first cooling medium or the second cooling medium.

[0107] In one embodiment of this application, the cooling device 1300 further includes a controller. The controller is electrically connected to the aforementioned detection elements 400 and the storage tank 500. The controller is used to control the automatic dosing process of the storage tank 500 in real time based on the detection results of each detection element 400. Taking the first cooling medium as an example, a database can be established based on the historical data of the first cooling medium to determine the alarm threshold. When the water quality parameters (conductivity, pH, or turbidity) in the first cooling medium reach the alarm threshold, the controller controls the storage tank 500 to actively replenish the chemical solution into the secondary side inlet pipe 210 or the secondary side outlet pipe 220. The treatment method for the second cooling medium is similar to that for the first cooling medium and will not be described in detail here.

[0108] This setup reduces the steps required for manual control of the first or second cooling medium water quality, improves the automation of the cooling equipment 1300, reduces human error in detection or untimely replacement, and enhances the stability and reliability of the cooling equipment 1300.

[0109] Continue reading Figure 13 In one embodiment of this application, the liquid storage tank 500 is connected to the secondary side inlet pipe 210 or the secondary side outlet pipe 220, and the outlet of the liquid storage tank 500 is located between the two first multi-way valves 250. That is, the junction of the liquid storage tank and the secondary side inlet pipe 210 or the secondary side outlet pipe 220 is located between the two first multi-way valves 250. With this configuration, the liquid storage tank 500 can be used to provide liquid for the first cooling medium in the working mode, and also to provide liquid for the cleaning fluid in the cleaning mode. In other words, the liquid storage tank 500 can function in both modes, taking into account the needs of both the first cooling medium and the cleaning fluid, achieving the effect of "one piece for multiple uses".
