[0002] For medium to large-scale data centers, liquid-liquid heat exchangers are widely used as core heat exchange equipment in current server chip liquid cooling systems due to their advantages such as high heat exchange efficiency, large heat transfer capacity, and high energy utilization efficiency. However, in some application scenarios, due to limitations in physical space, process piping, and other factors, liquid-liquid heat exchange cannot be used to cool servers. In such cases, air-liquid heat exchange can be used to cool servers. However, traditional air-liquid heat exchangers are limited by physical space, resulting in insufficient heat exchange area and number of fans, thus leading to low overall heat exchange efficiency.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] refer to Figures 1 to 3 The air-liquid heat exchange device 1000 in this embodiment may include a housing 100, a heat exchange module 200, a circulation pipe group 300, and an electrical control system 400, wherein the heat exchange module 200, the circulation pipe group 300, and the electrical control system 400 are all disposed inside the housing 100.

[0024] Specifically, the enclosure 100 may include a bottom plate 110, a top plate 120, and side plates, with the side plates connecting the bottom plate 110 and the top plate 120. The side plates may include two opposing first side plates 130 and two opposing second side plates 140, so that the enclosure 100 has an overall cuboid structure. For the sake of detailed description of the internal structure of the enclosure 100, the arrangement direction of the bottom plate 110 and the top plate 120 is defined as the first direction, the arrangement direction of the two first side plates 130 as the second direction, and the arrangement direction of the two second side plates 140 as the third direction.

[0025] like Figures 1 to 3 As shown, the space inside the enclosure 100 can be divided into an air inlet zone A, a heat exchange zone B, and an equipment zone C along the direction from the bottom plate 110 to the top plate 120. That is, the air inlet zone A is close to the bottom plate 110, and the equipment zone C is close to the top plate 120. The bottom plate 110 is provided with a bottom air inlet 111, and the top plate 120 is provided with a top air outlet 121. External air can enter the enclosure 100 through the bottom air inlet 111, pass through the air inlet zone A, the heat exchange zone B, and the equipment zone C in sequence, and then leave the enclosure 100 through the top air outlet 121.

[0026] The heat exchange module 200 is disposed in the heat exchange zone B. The heat exchange module 200 may include a fan-liquid heat exchanger 210 and a fan assembly 220 arranged along a first direction. Here, the fan-liquid heat exchanger 210 may be disposed above or below the fan assembly 220. Figure 2 The structure shown depicts a fan-liquid heat exchanger 210 positioned below a fan assembly 220. The fan assembly 220 may include multiple fans 2212, each with its axis parallel to a first direction. Coolant flows inside the fan-liquid heat exchanger 210. When external low-temperature gas flows into the housing 100, the fan assembly 220 drives the gas to flow from the bottom plate 110 towards the top plate 120, allowing the low-temperature gas to exchange heat with the fan-liquid heat exchanger 210, thereby lowering the temperature of the coolant inside the fan-liquid heat exchanger 210.

[0027] Figure 2Only one set of heat exchange modules 200 is shown in the illustration. In actual applications, at least one set of heat exchange modules 200 is used in this embodiment. When the number of heat exchange modules 200 is greater than or equal to two, multiple heat exchange modules 200 are arranged sequentially along the first direction. In this case, the circulation pipe assembly 300 is connected to multiple air-liquid heat exchangers 210 respectively, so as to cool the coolant through the multiple air-liquid heat exchangers 210, thereby improving the heat dissipation effect of the coolant. Furthermore, the increased number of fan assemblies 220 and air-liquid heat exchangers 210 not only increases the airflow in the housing 100 but also increases the heat exchange area between the gas and the air-liquid heat exchangers 210, thereby further improving the heat exchange efficiency with the coolant.

[0028] A circulation pipe assembly 300 is located in equipment area C and is connected to the air-liquid heat exchanger 210, allowing the coolant to circulate between the circulation pipe assembly 300 and the air-liquid heat exchanger 210. Furthermore, in conjunction with... Figure 2 and Figure 3 The side panel, corresponding to equipment area C, is also equipped with a return port 302 and a supply port 301. The circulation pipes in the circulation pipe assembly 300 are connected to the return port 302 and the supply port 301, respectively. The return port 302 and the supply port 301 are used to connect to the server, allowing coolant to enter the server and dissipate heat from the heat-generating components inside. In this way, the high-temperature coolant that has exchanged heat with the heat-generating components inside the server can enter the circulation pipes through the return port 302, and then flow into the air-liquid heat exchanger 210. After exchanging heat with the low-temperature gas in the enclosure 100, the low-temperature coolant returns to the circulation pipes, and then flows back to the server through the supply port 301. Thus, through the synergistic cooperation of air cooling and liquid cooling, the server can be efficiently cooled.

[0029] It is worth mentioning that during the process of the low-temperature gas flowing towards the top plate 120, the low-temperature gas flows through the circulation pipe assembly 300, and the low-temperature gas can also exchange heat with the coolant in the circulation pipe assembly 300, thereby playing a secondary cooling effect on the coolant in the circulation pipe assembly, so as to further improve the heat dissipation efficiency.

[0030] Continue to refer to Figure 2 The electrical control system 400 is located in equipment area C, and the projection of the electrical control system 400 along the first direction does not overlap with the projection of the circulation pipe assembly 300 along the first direction. In other words, the circulation pipe assembly 300 and the electrical control system 400 are relatively independent, thereby achieving water and electricity separation and ensuring the safety of product operation.

[0031] In this embodiment, the space within the enclosure 100 is partitioned, placing devices with different functions in different areas. This not only effectively utilizes the internal space of the enclosure 100 but also facilitates future partitioning and maintenance. In this design, the air inlet and outlet are respectively located on the bottom plate 110 and top plate 120, increasing their area to allow more low-temperature gas to flow through the enclosure 100. By stacking the air-liquid heat exchanger 210 and the fan assembly 220, compared to the traditional flat arrangement, this design increases the area of ​​both the air-liquid heat exchanger 210 and the fan assembly 220, thereby increasing the heat exchange area and the number of fans, thus improving the heat exchange efficiency of the air-liquid heat exchange device 1000.

[0032] Furthermore, by designing the fan 2212 with its axis parallel to the first direction, and given the small size of the fan 2212 along its axis, placing the fan 2212 horizontally reduces the space occupied by the fan 2212 in the housing 100 in the first direction. This allows for the arrangement of more than one layer of fans 2212 within the housing 100, thereby increasing the number of fans 2212 and further improving heat exchange efficiency. Simultaneously, the stacked arrangement of the air-liquid heat exchanger 210, the circulation pipe assembly 300, and the fan assembly 220 along the first direction enables the low-temperature gas to exchange heat with both the air-liquid heat exchanger 210 and the circulation pipe assembly 300, further enhancing heat exchange efficiency.

[0033] In some embodiments, reference is also made to Figures 3 to 5 The circulation pipe assembly 300 may specifically include a circulation supply pipe 303, a circulation return pipe 304, and a circulation pump 305. The circulation supply pipe 303 is connected to the supply port 301, and the circulation return pipe 304 is connected to the return port 302. The circulation pump 305 is installed in either the circulation supply pipe 303 or the circulation return pipe 304 to provide power for the circulation of the coolant. The circulation supply pipe 303 and the circulation return pipe 304 are also connected to the air-cooled heat exchanger 210, so that the coolant can enter the air-cooled heat exchanger 210 for heat exchange.

[0034] In addition, the circulation pipe assembly 300 may also include a pressure sensor 306, a temperature sensor 307, a flow sensor 308, a pressure stabilizing tank 309, a coolant replenishment tank 310, a bypass pipe 311, an electric bypass valve 312, and a coolant replenishment pump 315. The pressure sensor 306 is used to detect the pressure in the circulation pipe, the temperature sensor 307 is used to detect the temperature of the coolant at the supply port 301 and the return port 302, and the flow sensor 308 is used to detect the flow rate of the coolant in the circulation pipe. The coolant replenishment tank 310 replenishes the circulation pipe with coolant according to parameters such as flow rate and pressure. The two ends of the coolant replenishment pump 315 are connected to the coolant replenishment tank 310 and the circulation return pipe 304, respectively, to drive the coolant in the coolant replenishment tank 310 into the circulation return pipe 304. The pressure stabilizing tank 309 is used to ensure the pressure at the supply port 301 is stable. The two ends of the bypass pipe 311 can be connected to the two ends of the circulating pump 305, for example. The electric bypass valve 312 is installed on the bypass pipe 311. The flow rate in the air-liquid heat exchanger 210 can be adjusted by opening or closing the electric bypass valve 312, thereby ensuring the normal operation of the circulating system.

[0035] In practical applications, multiple temperature sensors 307, pressure sensors 306, and flow sensors 308 can be arranged to more accurately collect liquid parameters in the circulation pipe group 300, thereby improving the efficiency of the heat exchange device.

[0036] In some embodiments, such as Figure 1 and Figure 2 As shown, in practical applications, the first direction can be understood as the height direction of the housing 100, the second direction as the width direction of the housing 100, and the third direction as the length direction of the housing 100. When the circulation pipe assembly 300 and the electrical control system 400 are arranged in equipment area C, they can be arranged along the third direction. Since the housing 100 has a larger dimension in the third direction, there is sufficient space to divide equipment area C into two areas: water and electricity. (Reference) Figure 3 The liquid supply port 301 and the liquid return port 302 can be located on the second side plate 140 near the circulation pipe assembly 300, corresponding to the equipment area C, so that the circulation pipe assembly 300 can be connected to the liquid supply port 301 and the liquid return port 302 respectively.

[0037] To further improve heat exchange efficiency, combined with Figure 2 , Figure 3 and Figure 6The two first side plates 130, corresponding to the air inlet area A, may also be provided with first side air inlets 131, and the second side plate 140a, close to the electronic control system 400, may also be provided with second side air inlets 141 corresponding to the air inlet area A. By providing side air inlets, low-temperature gas at 270° can be supplied from the side, which can further increase the total area of ​​the air inlets, thereby increasing the air volume in the housing 100 and improving the heat exchange efficiency with the air-liquid heat exchanger 210 and the circulation pipe assembly 300.

[0038] A side air outlet 142 may also be provided on the second side plate 140b near the circulation pipe assembly 300, corresponding to the equipment area C, to increase the total area of ​​the air outlet and thereby improve the air circulation flow rate in the housing 100. Furthermore, a top air outlet 121 may also be provided on the top plate 120 corresponding to the circulation pipe assembly 300. For example, in the third direction, the ratio of the area of ​​the portion of the top plate 120 corresponding to the circulation pipe assembly 300 to the area of ​​the top plate 120 itself is approximately 2 / 3, so the top air outlet 121 is located at 2 / 3 of the top plate 120. In this way, in the horizontal direction, the air inlet and outlet of the housing 100 can be relatively independent, preventing turbulence in the air within the housing 100 and thus ensuring heat exchange efficiency.

[0039] Continue to refer to Figure 6 A replenishment port 314 and an overflow port 313 may also be provided on the second side plate 140b near the circulation pipe assembly 300, corresponding to the equipment area C. One end of the replenishment port 314 can be connected to... Figure 4 or Figure 5 The coolant tank 310 shown is connected to a liquid supply device outside the tank 100, and the other end of the liquid supply port 314 can be connected to ensure sufficient coolant in the coolant tank 310. The overflow port 313 is connected to... Figure 4 The circulating supply line 303 or circulating return line 304 shown in the illustration, exemplarily, may have an overflow port 313 with an internal threaded fitting and equipped with a combination of a pneumatic quick-connect fitting and a hose, which can meet the directional discharge of overflow liquid.

[0040] Furthermore, refer again Figure 6 The second side plate 140b, corresponding to the part of the equipment area C, is also provided with a network communication interface 143. The network communication interface 143 may include, for example, an RJ45 communication interface and a DB9 communication interface. The sensors and other structures set in the circulation tube group 300 may be connected to the DB9 communication interface to realize data transmission. The device can be connected to the network through the RJ45 communication interface to ensure stable communication.

[0041] The ports and interfaces on the second side plate 140b can be designed according to the actual layout requirements. For example, the liquid replenishment port 314 can be set on the second side plate 140b at a position corresponding to the equipment area C near the heat exchange area B, so that the liquid replenishment port 314 can be located at a low position of the circulation pipe group 300. At the same time, the liquid replenishment port 314 can also be equipped with a UQD quick connector to ensure that the liquid does not leak when passing through the liquid replenishment port 314.

[0042] Furthermore, combined Figure 5 and Figure 7 The liquid supply port 301 may include a filter housing 3011, a filter element structure 3012, and a filter element fixing structure 3013. The filter housing 3011 may be made of stainless steel and is installed through the second side plate 140b, such that a portion of the filter housing 3011 is located inside the housing 100, and another portion is located outside the housing 100. The filter housing 3011 includes an inlet 30111, an outlet 30112, and a reserved port 30113. The inlet 30111 and the reserved port 30113 are located inside the housing 100. The inlet 30111 is connected to the circulating liquid supply pipeline 303 shown in the figure. The outlet 30112 is located outside the housing 100 for connection to a server.

[0043] Specifically, the outlet 30112 and the reserved port 30113 are located at opposite ends of the filter housing 3011, and the axes of both the outlet 30112 and the reserved port 30113 are parallel to a third direction. The inlet 30111 is located between the outlet 30112 and the reserved port 30113, and the axis of the inlet 30111 is parallel to the first direction. The reserved port 30113 can be used to install a pressure sensor, which can be used to detect the pressure at the supply port 301, thereby determining whether there is a blockage in the filter housing 3011. In this way, by setting three ports at the supply port 301, not only can the flow of coolant be realized, but the installation of the pressure sensor is also facilitated.

[0044] The filter element structure 3012 is installed inside the filter housing 3011. The axis of the filter element structure 3012 is parallel to a third direction, and the filter element structure 3012 extends from the outlet 30112 to the reserved port 30113. When the coolant in the circulation pipe assembly 300 enters the filter housing 3011 through the inlet 30111, the filter element structure 3012 can filter the coolant. The filtered coolant then flows to the server through the outlet 30112, thereby ensuring the cleanliness of the coolant entering the server.

[0045] The filter element fixing structure 3013 is fixedly connected to the filter element structure 3012, and the filter element fixing structure 3013 is detachably connected to the end of the filter housing 3011 that has the liquid outlet 30112. When it is necessary to replace or maintain the filter element structure 3012, the filter element fixing structure 3013 can be separated from the filter housing 3011, and then the filter element structure 3012 and the filter element fixing structure 3013 can be pulled out from the filter housing 3011 in a third direction. The operation is simple and convenient.

[0046] Furthermore, a filter element sealing ring 3014 can be provided between the end of the filter element structure 3012 near the reserved port 30113 and the filter housing 3011, and the filter element sealing ring 3014 is located between the reserved port 30113 and the liquid inlet 30111. In this way, when the coolant enters the filter housing 3011 from the liquid inlet 30111, the coolant can only flow to the liquid outlet 30112 due to the obstruction of the filter element sealing ring 3014, which effectively ensures the flow direction of the coolant at the liquid supply port 301.

[0047] As an optional implementation, the inlet 30111, outlet 30112, and reserved port 30113 can all be quick-release chuck interfaces. Correspondingly, the filter element fixing structure 3013 can be an internally threaded hexagonal chuck, facilitating quick and easy installation and removal between the filter element fixing structure 3013 and the filter housing 3011. In this case, the filter element fixing structure 3013 can also be connected to a quick connector, such as a UQD quick connector, for connection to a server. A chuck sealing ring 3015 can also be provided between the filter element fixing structure 3013 and the filter housing 3011 to ensure the sealing at the connection between the filter element filter structure and the filter housing 3011, preventing coolant leakage.

[0048] In addition, the pressure sensor located at the reserved port 30113 can also be configured as a chuck-type quick-release sensor, so that the pressure sensor can be quickly and efficiently installed and removed from the reserved port 30113.

[0049] Understandably, in this embodiment, the filter structure and the liquid supply port 301 are designed as an integrated structure, which not only effectively filters the coolant and prevents particulate impurities in the pipeline from entering the server, but also simplifies the pipeline design.

[0050] In some embodiments, combined with Figure 3 and Figure 8The heat exchange module 200 may further include a mounting bracket 230, which includes a support plate 231 and two mounting plates 232. The support plate 231 is arranged parallel to the base plate 110, and the air-liquid heat exchanger 210 can be fixed to the side of the support plate 231 facing the base plate 110. The two mounting plates 232 are respectively connected to the two sides of the support plate 231 along a third direction. The mounting plates 232 protrude from the side of the support plate 231 facing the base plate 110, and are perpendicular to the support plate 231, so that the mounting bracket 230 as a whole forms a U-shaped structure.

[0051] The mounting plate 232 is fixedly connected to the side plate so that the mounting bracket 230 can be relatively fixed to the housing 100. For example, the mounting plate 232 can be connected to the first side plate 130 by screws. Furthermore, each mounting plate 232 may also be provided with a carrying handle 234 on the side facing the second side plate 140. The carrying handle 234 can rotate relative to the mounting plate 232 so that the carrying handle 234 is either stored on the surface of the mounting plate 232 or protrudes from the surface of the mounting plate 232. When assembling the heat exchange module 200 with the housing 100, the carrying handle 234 can be used to move the mounting bracket 230, thereby placing the heat exchange module 200 inside the housing 100.

[0052] The two second side plates 140 may each be provided with mounting plate clearance grooves for avoiding the mounting plate 232. When the mounting bracket 230 is assembled with the housing 100, the outer surfaces of the two mounting plates 232 can be flush with the outer surfaces of the second side plates 140, so that the overall appearance of the housing 100 is neater.

[0053] Continue to refer to Figure 3 , Figure 8 and Figure 9 The fan assembly 220 is located on the side of the support plate 231 away from the bottom plate 110. The support plate 231 can support and fix the fan assembly 220 so that the fan assembly 220 can be relatively fixed with the housing 100.

[0054] The fan assembly 220 may include at least one set of fan modules 221, each set of fan modules 221 including a fan housing 2211 and at least one fan 2212. The fan housing 2211 may have multiple compartments arranged along a third direction, each compartment being used to install one fan 2212, which can be fixed to the fan housing 2211 with bolts. When there are two or more fan modules 221, the multiple fan modules 221 may be arranged along a second direction. In this way, each fan module 221 can be installed independently with the mounting bracket 230, and each fan 2212 can be installed independently with the fan housing 2211, so as to flexibly adjust the number of fans 2212 and facilitate maintenance.

[0055] The second side panel 140b, facing inwards from the housing 100, has at least one fan connector (not shown in the figure) corresponding to at least one set of fan modules 221. Each fan box 2211, facing the second side panel 140b, has a fan plug 2213. The fan plug 2213 can be moved relative to the housing 100 in a third direction to be inserted into or detached from the fan connector. That is, the fan box 2211 can be moved relative to the mounting bracket 230 in a third direction so that the fan plug 2213 is close to the fan connector, thereby allowing the fan plug 2213 to be inserted into the fan connector so that each fan 2212 in the fan box 2211 can be powered. When maintenance is required on one set of fan modules 221, the fan box 2211 can be moved away from the fan connector so that the fan plug 2213 is detached from the fan connector. It is understood that when one set of fan modules 221 is maintained, the remaining fan modules 221 can operate normally without affecting the heat dissipation within the housing 100.

[0056] In a specific implementation, the fan plug 2213 can be an aviation quick-connect. Each fan 2212 in the fan box 2211 can be connected to the fan plug 2213 via an aviation plug wiring to achieve a conductive connection between each fan 2212 and the fan plug 2213.

[0057] Furthermore, a limiting plate 233 may be provided on the support plate 231 near the second side plate 140b, and the limiting plate 233 is fixed relative to the support plate 231. The limiting plate 233 has a limiting surface parallel to the second side plate 140b for abutting against the support plate 231, thereby limiting the position of the fan box 2211 to ensure that the fan plug 2213 can remain plugged into the fan 2212 connector. Moreover, when the support plate 231 abuts against the limiting plate 233, screws can be used to fix the support plate 231 and the limiting plate 233 together to ensure the fixation effect of the fan plug 2213 and the fan connector, and to prevent poor contact between the fan plug 2213 and the fan connector during operation from affecting the heat dissipation effect.

[0058] The fan housing 2211 may also be equipped with a pull-out handle 2214. The pull-out handle 2214 and the fan plug 2213 are located on both sides of the fan housing 2211 along a third direction, that is, the pull-out handle 2214 is located near the second side panel 140a. When it is necessary to remove the fan module 221 from the housing 100, the fan housing 2211 can be pulled outward by using the pull-out handle 2214 for easy operation.

[0059] Furthermore, refer again Figure 3 and Figure 8 The air-liquid heat exchanger 210 may include a liquid inlet 211 and a liquid outlet 212. The liquid inlet 211 can be connected to... Figure 4The circulating return pipeline 304 is connected, and the outlet port 212 can be connected to... Figure 4 The circulating coolant supply pipe 303 is connected. The high-temperature coolant enters the air-liquid heat exchanger 210 through the circulating return pipe 304 and the inlet port 211. After heat exchange, the low-temperature coolant can enter the circulating coolant supply pipe 303 through the outlet port 212 and then flow to the server.

[0060] Since the circulation pipe assembly 300 is located on the side of the support plate 231 away from the bottom plate 110, to facilitate the connection of the inlet port 211 and the return port to the circulation pipe assembly 300, the inlet port 211 and the outlet port 212 can be located on the support plate 231 near the second side plate 140b. Furthermore, the inlet port 211 and the outlet port 212 are respectively inserted through the support plate 231, so that a portion of the inlet port 211 and the outlet port 212 are located on the side of the support plate 231 away from the bottom plate 110. This allows the inlet port 211 and the outlet port 212 to be connected to the circulation pipe assembly 300 via connecting pipes. Specifically, the inlet port 211 and the outlet port 212 can each use a quick-connect chuck connector and be connected to the connecting pipes via quick-connect clamps.

[0061] In this embodiment, the air-liquid heat exchanger 210 can be, for example, a copper tube and copper sheet structure dry cooler, which may be provided with a vent and an exhaust port, wherein the vent and exhaust port may be located at the branch pipe of the copper tube. By providing an exhaust port, the gas in the air-liquid heat exchanger 210 can be discharged when coolant is injected into the air-liquid heat exchanger 210. By providing a vent, the internal coolant can be discharged when the air-liquid heat exchanger 210 is maintained.

[0062] In some embodiments, continue to refer to Figure 3 A water-electricity separation plate 500 can be installed between the circulation pipe assembly 300 and the electrical control system 400. The two ends of the water-electricity separation plate 500 can be respectively connected to… Figure 1 The two first side panels 130 shown are connected to separate the water and electrical circuits using the water-electricity separation plate 500. As previously described, the circulation pipe assembly 300 and the electrical control system 400 are arranged along a third direction, thus, in conjunction with the water-electricity separation plate 500, the potential threat of water and electricity mixing can be resolved through both spatial isolation and material protection.

[0063] Combination Figure 3 and Figure 10The electronic control system 400 may include a circuit board 410, a power supply housing 420, and a power module 430. The power supply housing 420 has openings at both ends along a third direction. The circuit board 410 is fixed to one of these openings and is fixedly connected to the water-electricity separation plate 500. A power slot 411 is provided on the side of the circuit board 410 facing the power supply housing 420. The power module 430 can be movably inserted into the power supply housing 420 through the other opening along a third direction. A power plug-in structure 431 may be provided on the side of the power module 430 facing the circuit board 410, and the power plug-in structure 431 can be plugged into the power slot 411. For example, the power plug-in structure 431 may be a hot-swappable gold finger.

[0064] Combination Figure 3 , Figure 6 and Figure 10 The second side plate 140b may also be provided with a power interface 144. The power module 430 can be connected to the power interface 144 via a connecting cable to supply power to the power interface 144. It is understandable that placing the power interface 144 on the second side plate 140b not only facilitates the connection of the power interface 144 to components such as the fan 2212 connector and the circulation pump 305, avoiding messy cable routing, but also enables the power module 430 to supply power to various components, ensuring the normal operation of the device.

[0065] In this embodiment, there can be two power modules 430, arranged along the first direction and respectively plugged into the circuit board 410. One power module 430 can serve as a backup. When the normally used power module 430 needs maintenance, the backup power module 430 can be used, thus enabling online operation and maintenance and improving product maintenance efficiency. Correspondingly, there can also be two power interfaces 144 on the second side panel 140b. One power interface 144 is connected to the normally used power module 430, and the other power interface 144 is connected to the backup power module 430.

[0066] In some embodiments, combined with Figure 2 and Figure 11 The air-liquid heat exchange device may include an air inlet baffle plate 600 disposed in the air inlet zone A, and the air inlet baffle plate 600 and the base plate 110 may be arranged at intervals. The air inlet baffle plate 600 is provided with a plurality of air inlet holes 610 arranged at intervals along a third direction. The air inlet holes 610 may be elongated, and each air inlet hole 610 extends along a second direction.

[0067] The base plate 110 is provided with a plurality of liquid collection tanks 112 arranged at intervals along a third direction. The bottom air inlet 111 is formed at the part of the base plate 110 between any two adjacent liquid collection tanks 112. The bottom air inlet 111 can also be elongated. Each bottom air inlet 111 extends along a second direction.

[0068] Figure 11 Solid arrows indicate the direction of gas flow, while dashed arrows indicate the direction of liquid flow. In this embodiment, the air inlet 610 can be positioned directly opposite the liquid collection tank 112, and each bottom air inlet 111 can be positioned directly opposite the location between two adjacent air inlets 610. Furthermore, the projection of the liquid collection tank 112 along the first direction overlaps with the projection of the air inlet along the first direction. That is, in the third direction, the bottom air inlets 111 and the air inlets 610 are staggered. When gas from outside the housing 100 enters the space between the bottom plate 110 and the air inlet baffle plate 600 through the bottom air inlet 111, the gas can diffuse to both sides and then flow from the obliquely upward air inlet toward the heat exchange zone B.

[0069] Understandably, when the air-liquid heat exchanger 210 or the circulation pipe assembly 300 located above the air inlet baffle 600 leaks, the leaked coolant drips onto the air inlet baffle 600 under gravity, and then falls into the collection tank 112 through the air inlet hole 610. Thus, through the cooperation of the air inlet baffle 600 and the base plate 110, the leaked coolant can be collected, enabling efficient monitoring of whether there is any leakage inside the housing 100.

[0070] In specific configuration, the dimension of the collection tank 112 along the first direction can be greater than or equal to 10mm. Due to the relatively large height of the collection tank 112, it can effectively collect leaked coolant. In addition, each collection tank 112 can be equipped with a leakage alarm device. When there is liquid in any of the collection tanks 112, the leakage alarm device can issue an alarm in time, thereby realizing real-time monitoring of leakage.

[0071] Based on the same inventive concept, and referring to Figure 12 and Figure 13 This application embodiment can also provide a wind-liquid heat exchange system, which may include a cabinet 10, an inlet liquid distribution pipe 20, a return liquid distribution pipe 30, and a wind-liquid heat exchange device 1000 as described in the foregoing embodiments, wherein the wind-liquid heat exchange device 1000, the inlet liquid distribution pipe 20, and the return liquid distribution pipe 30 are all disposed within the cabinet 10. Furthermore, the cabinet 10 can also be used to house a server 1 for heat exchange via the wind-liquid heat exchange device 1000.

[0072] The dimensions of the air-liquid heat exchanger 1000 can be designed to meet the installation dimensions of a standard server rack 10. For example, the length, width, and height of the air-liquid heat exchanger 1000 can be 865mm, 445mm, and 390mm, respectively. When the air-liquid heat exchanger 1000 is placed in the rack 10, it can be positioned close to the bottom of the rack 10. Furthermore, an L-shaped support plate 40 can be installed on the inner wall of the rack 10, with a portion of the L-shaped support plate 40 extending towards the center of the rack 10, thereby supporting and securing the air-liquid heat exchanger 1000.

[0073] In addition, combined Figure 6 and Figure 12 The side panel of the enclosure 100 may also be equipped with a limiting handle 132. For example, the limiting handle 132 may be located on the first side panel 130. When the air-liquid heat exchanger 1000 is placed in the cabinet 10, the limiting handle on the first side panel 130 can abut against the inner wall of the cabinet 10, thereby ensuring that the enclosure 100 is installed in place. Specifically, the inner wall of the cabinet 10 may be equipped with a U-shaped plate, with the opening of the U-shaped plate facing the limiting handle 132. The limiting handle 132 can be inserted into the U-shaped plate to limit the movement between the air-liquid heat exchanger 1000 and the cabinet 10.

[0074] Continue to refer to Figure 12 and Figure 13 , Figure 13 Due to the angle, only the structure of the return liquid distribution pipe 30 is shown. The inlet liquid distribution pipe 20 and the return liquid distribution pipe 30 can be respectively installed on opposite sides of the cabinet 10, and both extend along a first direction. The inlet liquid distribution pipe 20 and... Figure 3 The liquid supply port 301 is connected, and the return liquid distribution pipe 30 is connected to... Figure 3 Connect to the return port 302 in the middle.

[0075] The liquid inlet separator 20 is connected to multiple liquid inlet UQD connectors 21 along the first direction, and the liquid return separator 30 is connected to multiple liquid return UQD connectors 31 along the first direction, with one liquid inlet UQD connector 21 and one liquid return UQD connector 31 correspondingly set.

[0076] Server 1 can be positioned above the air-liquid heat exchanger 1000. When multiple servers 1 are placed in the rack 10, they are stacked along a first direction. Each server 1 can be connected to an inlet UQD connector 21 and a return UQD connector 31 to maintain connection between the server 1 and the inlet and return distribution pipes 20 and 30. When the server 1 is running, the low-temperature coolant in the air-liquid heat exchanger 1000 enters the inlet distribution pipe 20 through the supply port 301, and then enters the server 1 through the inlet UQD connector 21, where it exchanges heat with the heating elements inside the server 1. The high-temperature coolant enters the return distribution pipe 30 through the return UQD connector 31, and then returns to the air-liquid heat exchanger 1000 through the return port 302, where it is further heated by the heat exchange structure inside the air-liquid heat exchanger 1000.

[0077] In the aforementioned air-liquid heat exchange system, the coolant, driven by a circulating pump, is continuously circulated within the server, absorbing heat and rising to a high-temperature liquid. This liquid then passes through an air-liquid heat exchanger to achieve heat exchange between the air and the liquid. The operating principle is relatively simple and easy to implement. Furthermore, the air-liquid heat exchanger can be used as a standalone device, applicable to various scenarios, thus enhancing its versatility.

[0078] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this utility model without departing from the spirit and scope of this utility model. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
