Description

Technical Field

[0001] This application relates to the field of refrigeration technology, specifically to a cold capacity distribution device and a cooling system. Background Technology

[0002] Servers and similar equipment typically rely on cooling systems to prevent overheating and disruption to operation. These systems include cooling equipment and a cooling distribution unit. The distribution unit is connected to both the cooling equipment and the liquid cooling plates within the server. It cools the server by using a primary coolant sourced from the cooling equipment to cool a secondary coolant within the liquid cooling plates. However, if the cooling distribution unit malfunctions, the cooling system cannot cool the secondary coolant within the liquid cooling plates, thus affecting server operation. Summary of the Invention

[0003] This application provides a cooling distribution device and a cooling system, which can ensure that the cooling distribution device works continuously and that the server works normally.

[0004] In a first aspect, embodiments of this application provide a cooling capacity distribution device, including a housing, a plurality of cooling capacity distribution units, and a plurality of connector units. The plurality of cooling capacity distribution units are disposed within a cavity enclosed by the housing. Each cooling capacity distribution unit can be detachably connected to a cooling device and a liquid cooling plate via a connector unit. The cooling capacity distribution unit is used for heat exchange between a first coolant and a second coolant. The connector unit is used to prevent the first coolant and the second coolant from flowing out in the detached state.

[0005] The cooling distribution device includes multiple cooling distribution units connected in parallel and detachably connected to the cooling equipment and liquid cooling plate. If one cooling distribution unit fails, it can switch to another cooling distribution unit to ensure the cooling distribution device continues to work and the server works normally.

[0006] Meanwhile, the connector unit can prevent the first and second coolants from flowing out when disassembled, avoiding coolant leakage and ensuring that the faulty cooling distribution unit can be removed to the external space for maintenance in a timely manner, thus improving the maintainability and ease of operation of the cooling distribution device.

[0007] In some embodiments that may include the above embodiments, the housing includes an inlet and a bottom end opposite to the inlet, and the connector unit is disposed between the cold energy distribution unit and the bottom end.

[0008] The inlet is used for loading and unloading the cooling capacity distribution unit. The connector unit is located between the cooling capacity distribution unit and the bottom end. The connection direction of the connector unit is parallel to the movement direction of the cooling capacity distribution unit. By pushing and pulling the cooling capacity distribution unit, the connection and disconnection of the connector unit can be achieved.

[0009] In some embodiments that may include the above embodiments, a groove is provided on the surface of the housing, and a pulley is provided on the surface of the cold energy distribution unit, with at least a portion of the pulley located in the groove.

[0010] The combination of pulleys and slides can reduce the force required for disassembling and installing the cooling distribution unit, thus reducing the difficulty of operating the cooling distribution unit.

[0011] In some embodiments that may include the above embodiments, the connector unit includes a first sub-connector, a second sub-connector, a third sub-connector, and a fourth sub-connector. One end of the first sub-connector is connected to the water inlet of the cooling device, and the other end of the first sub-connector is connected to the first water outlet of the cooling capacity distribution unit. One end of the second sub-connector is connected to the water outlet of the cooling device, and the other end of the second sub-connector is connected to the first water inlet of the cooling capacity distribution unit.

[0012] One end of the third sub-connector is connected to the inlet of the liquid cooling plate, and the other end of the third sub-connector is connected to the second outlet of the cooling capacity distribution unit. One end of the fourth sub-connector is connected to the outlet of the liquid cooling plate, and the other end of the fourth sub-connector is connected to the second inlet of the cooling capacity distribution unit.

[0013] The first and second sub-connectors can connect the cooling distribution unit and the cooling equipment, while the third and fourth sub-connectors can connect the cooling distribution unit and the liquid cooling plate, thereby enabling heat exchange between the first coolant from the cooling equipment and the second coolant from the liquid cooling plate.

[0014] In some embodiments that may include the above embodiments, the first sub-connector includes a first connector and a second connector. The first connector includes a first pipe body and a first valve structure, and the second connector includes a second pipe body and a second valve structure. The first pipe body is connected to the first outlet of the cooling capacity distribution unit, and the first valve structure is disposed within the first pipe body for sealing the first pipe body.

[0015] The second pipe is mounted on the outer casing and is connected to the water inlet of the cooling equipment. A second valve structure is located inside the second pipe and is used to close the second pipe. In the assembled state, the first and second pipes are connected, triggering both the first and second valve structures, causing them to open.

[0016] The first sub-connector can realize the connection and disconnection of the first pipe body and the second pipe body, which can ensure the normal operation of the cooling distribution unit, and reduce the difficulty of disassembling the cooling distribution unit in case of failure, and can avoid coolant leakage during the disassembly of the cooling distribution unit.

[0017] In some embodiments that may include the above embodiments, the first valve structure includes a first spring, a first fixing member, and a first valve core. The first fixing member is provided with a first sealing surface. The first spring is connected to the first valve core and the first pipe body. The first spring is used to drive the first valve core to move out of the first pipe body so that the first valve core contacts the first sealing surface, thereby sealing the first pipe body.

[0018] The second valve structure includes a second spring, a second fixing member, and a second valve core. The second fixing member is provided with a second sealing surface. The second spring is connected to the second valve core and the second pipe body. The second spring is used to drive the second valve core to move out of the second pipe body so that the second valve core contacts the second sealing surface, thereby sealing the second pipe body.

[0019] In the assembled state, the first valve core abuts against the second fixing member, the second valve core abuts against the first fixing member, the first valve core moves toward the direction of the first spring, the first valve core separates from the first sealing surface, the second valve core moves toward the direction of the second spring, the second valve core separates from the second sealing surface, so that the first tube body and the second tube body are connected.

[0020] The first valve core abuts against the second fixing member, and the second valve core abuts against the first fixing member. The first spring and the second spring are compressed, so that a flow channel is formed between the first valve structure and the second valve structure, and the coolant can flow in the flow channel to realize the connection between the first pipe body and the second pipe body.

[0021] When the first valve core is pushed by the first spring and the second valve core is pushed by the second spring, the first valve core moves toward the first sealing surface and contacts the first sealing surface, and the second valve core moves toward the second sealing surface and contacts the second sealing surface, so that the first pipe body and the second pipe body are sealed, thereby preventing coolant leakage.

[0022] In some embodiments that may include the above embodiments, the cooling capacity distribution unit further includes a locking structure, and a mating structure is provided on the outer shell. The locking structure and the mating structure cooperate to prevent the cooling capacity distribution unit from moving out of the cavity.

[0023] The locking structure and the mating structure work together to prevent the cold distribution unit from moving out of the cavity, so that the first connector is continuously subjected to thrust, ensuring that the first connector and the second connector are connected.

[0024] In some embodiments that may include the above-described embodiments, the locking structure includes a fixed base, a locking rod, and a snap-fit ​​structure. The fixed base is connected to the cooling distribution unit, the locking rod is hinged to the fixed base, and the snap-fit ​​structure is disposed at the first end of the locking rod. The mating structure includes a locking hole disposed on the housing. When the locking structure is in the locked state, the snap-fit ​​structure snaps into the fixed base to prevent the locking rod from rotating, and the second end of the locking rod extends into the locking hole. When the locking structure is in the unlocked state, the snap-fit ​​structure disengages from the fixed base, and the second end of the locking rod is located outside the locking hole.

[0025] The locking rod is hinged to the mounting base, allowing it to connect to the cooling distribution unit. The mating structure includes a locking hole on the housing; the locking rod engages with the locking hole to secure the cooling distribution unit to the housing. A snap-fit ​​mechanism is located at the first end of the locking rod; by controlling this mechanism, the rotation direction and angle of the locking rod can be controlled.

[0026] The locking rod engages with the locking hole to fix the position of the cold distribution unit, preventing the cold distribution unit from moving out of the cavity, thereby keeping the first spring and the second spring in a compressed state, and keeping the first connector and the second connector connected.

[0027] In some embodiments that may include the above-described embodiments, the snap-fit ​​structure includes a snap-fit ​​rod, which is hinged to the first end. The snap-fit ​​end of the snap-fit ​​rod is provided with a hook portion, and a fixing block is provided on the fixing base. When the locking structure is in the locked state, the hook portion hooks onto the fixing block.

[0028] The locking rod is hinged to the first end, meaning that the locking rod and the first end of the locking rod can be connected via a rotating shaft, allowing the locking rod to rotate around the shaft. The locking end of the locking rod is equipped with a hook, and the fixed base is equipped with a fixing block. Since the locking rod can rotate, the hook can also rotate. After the hook rotates a certain angle, it can hook onto the fixing block, thereby fixing the angle and position of the locking rod.

[0029] In some embodiments that may include the above embodiments, the snap-fit ​​structure further includes a first elastic element, which is connected to the fixing seat and the snap-fit ​​rod. The first elastic element is used to prevent the snap-fit ​​rod from rotating in the direction in which the hook part disengages from the fixing block.

[0030] The latching rod is hinged to the first end. That is, when the latching rod is pressed, the hook will rotate at a certain angle. At this time, the hook will hook onto the fixed block, and the first elastic element will undergo elastic deformation, thereby generating a clamping force, so that the hook and the fixed block are firmly connected, preventing the hook from detaching from the fixed block under its own weight.

[0031] At the same time, after the hook part is separated from the fixing block, the first elastic element will gradually return to its initial state, so that the relative position of the hook part and the locking rod is restored to the initial state, ensuring that the hook part can continue to be used.

[0032] In some embodiments that may include the above embodiments, the locking structure further includes a second elastic element, which is used to drive the locking rod to rotate in the direction in which the second end disengages from the locking hole.

[0033] One end of the second elastic element is connected to the locking rod, and the other end is connected to the fixed base. When the locking structure is engaged with the fixed base, the position of the locking rod is fixed, and the second elastic element is stretched. When the locking structure disengages from the fixed base, the locking rod can rotate, and the second elastic element will return from its stretched state to its normal state, thus moving in the contraction direction. The locking rod connects to the second elastic element and moves with it, causing the second end of the locking rod to be located outside the locking hole.

[0034] Secondly, embodiments of this application provide a cooling system, including a cooling device and the aforementioned cold energy distribution device. The cold energy distribution device is connected to both the cooling device and a liquid cooling plate inside the server. The cold energy distribution device cools the second coolant inside the liquid cooling plate using a first coolant from the cooling device, thereby cooling the server.

[0035] The cooling system provided in this application includes the cooling capacity distribution device in any of the above embodiments. Therefore, both can solve the same technical problem and achieve the same technical effect. Attached Figure Description

Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments 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.

[0049] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0050] Furthermore, in the embodiments of this application, directional terms such as "up," "down," "left," "right," "horizontal," and "vertical" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0051] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0052] It should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection or an integral connection; they can also refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0053] Please refer to Figure 1 , Figure 1 The solid line represents the flow direction of cold water, and the dashed line represents the flow direction of hot water. Servers such as server 12 typically require a cooling system 10 for heat dissipation. The cooling system 10 includes a cooling device 11 and a cooling capacity distribution device 20. The cooling capacity distribution device 20 is connected to both the cooling device 11 and the liquid cooling plate 13 within the server 12. The cooling capacity distribution device 20 cools the second coolant within the liquid cooling plate 13 using the first coolant from the cooling device 11, thereby cooling the server 12.

[0054] Please refer to Figure 1 and Figure 2 Since the server 12 needs continuous heat dissipation, the cooling distribution device 20 needs to work continuously. In related technologies, the cooling distribution device 20 includes a housing 21, a cooling distribution unit 22, and a long pipe 14. The cooling distribution unit 22 and the long pipe 14 are disposed within the cavity 211 enclosed by the housing 21. The cooling distribution unit 22 is connected to the cooling device 11 and the liquid cooling plate 13 through the long pipe 14.

[0055] Understandably, the long tube 14 is relatively long. In the event of a malfunction in the cooling distribution unit 22, the cooling distribution unit 22 can be pulled out of the cavity 211 to ensure the connection between the cooling distribution unit 22 and the cooling equipment 11 and the liquid cooling plate 13. This allows for online maintenance of the cooling distribution unit 22 without affecting heat dissipation.

[0056] However, when the cooling distribution unit 22 is working normally, the long pipe 14 is located between the cooling distribution unit 22 and the outer casing 21, occupying a lot of space in the cavity 211, which is not conducive to the miniaturization of the cooling distribution device 20. When replacing the cooling distribution unit 22, the coolant needs to be drained, which increases the risk of coolant leakage. At the same time, the cooling distribution unit 22 is small in size and has compact internal components, making online disassembly and assembly difficult.

[0057] Please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the cooling capacity distribution unit 22 during normal operation. Figure 4 This is a schematic diagram showing the structure when the cooling capacity distribution unit 22 is removed. The cooling capacity distribution device 20 provided in this embodiment includes a housing 21, multiple cooling capacity distribution units 22, and multiple connector units 23. The multiple cooling capacity distribution units 22 are disposed within the cavity 211 enclosed by the housing 21. This embodiment does not limit the arrangement of the multiple cooling capacity distribution units 22. For example, the multiple cooling capacity distribution units 22 can be spaced apart along the width direction of the housing 21; the multiple cooling capacity distribution units 22 can also be spaced apart along the height direction of the housing 21.

[0058] Each cooling distribution unit 22 can be detachably connected to the cooling device 11 and the liquid cooling plate 13 via a connector unit 23. The cooling distribution unit 22 is used for heat exchange between the first coolant and the second coolant. The connector unit 23 is used to prevent the first coolant and the second coolant from flowing out in the detached state. The detached state refers to the state in which the cooling distribution unit 22 is separated from the cooling device 11 and the liquid cooling plate 13, and the assembled state refers to the state in which the cooling distribution unit 22 is connected to the cooling device 11 and the liquid cooling plate 13.

[0059] It is understood that the cooling distribution device 20 includes multiple cooling distribution units 22, which are connected in parallel and detachably connected to the cooling equipment 11 and the liquid cooling plate 13. If one cooling distribution unit 22 fails, the operation can be switched to another cooling distribution unit 22 to ensure the continuous operation of the cooling distribution device 20 and guarantee the operation of the server 12. Figure 1 (As shown) It is working normally.

[0060] The connector unit 23 can prevent the first and second coolants from flowing out in the disassembled state, avoiding coolant leakage and ensuring that the faulty cooling distribution unit 22 can be removed to the external space for maintenance in a timely manner, thereby improving the maintainability and ease of operation of the cooling distribution device 20.

[0061] Meanwhile, compared with the aforementioned related technologies, the cooling capacity distribution device 20 provided in this application embodiment can remove the faulty cooling capacity distribution unit 22 without online disassembly or online maintenance, which can reduce the maintenance difficulty of the cooling capacity distribution device 20.

[0062] In some embodiments, the cooling capacity distribution unit 22 includes a heat exchanger, and a first pipeline and a second pipeline are provided inside the heat exchanger. The first coolant flows out from the outlet of the cooling device 11 and flows into the first pipeline through the first inlet 222 of the cooling capacity distribution unit 22. The second coolant flows out from the outlet of the liquid cooling plate 13 of the server 12 and flows into the second pipeline through the second inlet 224 of the cooling capacity distribution unit 22.

[0063] Because the temperature of the second coolant flowing out of the liquid cooling plate 13 is higher and the temperature of the first coolant flowing out of the cooling device 11 is lower, there is a temperature difference between the first pipe and the second pipe, which will generate heat exchange. The temperature of the second coolant gradually decreases and the temperature of the first coolant gradually increases.

[0064] After the temperature of the first coolant rises, it returns to the inlet of the cooling device 11 through the first outlet 221 of the cooling distribution unit 22. After the temperature of the second coolant decreases, it returns to the liquid cooling plate 13 through the second outlet 223 of the cooling distribution unit 22 to continue cooling the server 12.

[0065] In some embodiments, the cooling capacity distribution device 20 further includes a water pump disposed between the inlet of the heat exchanger and the cooling device 11, and between the inlet of the heat exchanger and the liquid cooling plate 13. It is understood that the cooling capacity distribution device 20 is typically located at the bottom of the server 12, and there is a height difference between the cooling capacity distribution unit 22 and the cooling device 11 and the liquid cooling plate 13. The water pump can deliver coolant to the cooling device 11 and the liquid cooling plate 13.

[0066] In some embodiments, the cooling distribution device 20 further includes a temperature sensor, which is disposed between the inlet of the heat exchanger and the cooling device 11, and between the inlet of the heat exchanger and the liquid cooling plate 13. The temperature sensor can detect the temperature of the first coolant flowing back to the cooling device 11 and the temperature of the second coolant flowing back to the liquid cooling plate 13. The temperature difference between the first coolant and the second coolant can reflect the heat exchange capacity of the heat exchanger. The cooling system 10 can adjust the water volume of the first coolant and the second coolant according to the temperature difference, thereby adjusting the heat exchange capacity and ensuring the heat dissipation of the server 12.

[0067] In the above embodiment, the outer casing 21 includes an inlet 212 and a bottom end 213 opposite to the inlet 212, and the connector unit 23 is disposed between the cold energy distribution unit 22 and the bottom end 213.

[0068] It is understandable that the inlet 212 is used for loading and unloading the cooling capacity distribution unit 22, and the connector unit 23 is located between the cooling capacity distribution unit 22 and the bottom end 213. The connection direction of the connector unit 23 is parallel to the movement direction of the cooling capacity distribution unit 22. By pushing and pulling the cooling capacity distribution unit 22, the connector unit 23 can be turned on and off.

[0069] In the above embodiment, a groove is provided on the surface of the outer casing 21, and a pulley is provided on the surface of the cold energy distribution unit 22, with at least a portion of the pulley located in the groove.

[0070] Understandably, the combination of pulleys and slides can reduce the force required for disassembling and installing the cooling distribution unit 22, and reduce the difficulty of operating the cooling distribution unit 22.

[0071] Please refer to Figure 5 , Figure 5 The solid line represents the flow direction of cold water, and the dashed line represents the flow direction of hot water. In the above embodiment, the connector unit 23 includes a first sub-connector 31, a second sub-connector 32, a third sub-connector 33, and a fourth sub-connector 34. One end of the first sub-connector 31 is connected to the water inlet of the cooling device 11, and the other end of the first sub-connector 31 is connected to the first water outlet 221 of the cold energy distribution unit 22. One end of the second sub-connector 32 is connected to the water outlet of the cooling device 11, and the other end of the second sub-connector 32 is connected to the first water inlet 222 of the cold energy distribution unit 22.

[0072] One end of the third sub-connector 33 is connected to the inlet of the liquid cooling plate 13, and the other end of the third sub-connector 33 is connected to the second outlet 223 of the cooling capacity distribution unit 22. One end of the fourth sub-connector 34 is connected to the outlet of the liquid cooling plate 13, and the other end of the fourth sub-connector 34 is connected to the second inlet 224 of the cooling capacity distribution unit 22.

[0073] The first sub-connector 31 and the second sub-connector 32 can connect the cooling capacity distribution unit 22 and the cooling device 11, and the third sub-connector 33 and the fourth sub-connector 34 can connect the cooling capacity distribution unit 22 and the liquid cooling plate 13, thereby enabling heat exchange between the first coolant from the cooling device 11 and the second coolant from the liquid cooling plate 13.

[0074] Please refer to Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the structure of the first sub-connector 31. Figure 7This is a schematic diagram showing the structure of the first sub-connector 31. In the above embodiment, the first sub-connector 31 includes a first connector 41 and a second connector 42. The first connector 41 includes a first pipe body 43 and a first valve structure 44. The second connector 42 includes a second pipe body 45 and a second valve structure 46. The first pipe body 43 is connected to the first outlet 221 of the cooling capacity distribution unit 22. The first valve structure 44 is disposed inside the first pipe body 43 and is used to close the first pipe body 43.

[0075] The second pipe body 45 is installed on the outer casing 21 and is connected to the water inlet of the cooling device 11. The second valve structure 46 is installed inside the second pipe body 45 and is used to close the second pipe body 45.

[0076] In the assembled state, the first tube 43 and the second tube 45 are connected, and the first valve structure 44 and the second valve structure 46 are triggered, so that both the first valve structure 44 and the second valve structure 46 are opened.

[0077] The first sub-connector 31 can realize the connection and disconnection of the first pipe body 43 and the second pipe body 45, which can ensure the normal operation of the cooling distribution unit 22, and reduce the difficulty of disassembling the cooling distribution unit 22 when the cooling distribution unit 22 fails, thus avoiding coolant leakage during disassembly of the cooling distribution unit 22.

[0078] Continue to refer to Figure 6 and Figure 7 In the above embodiment, the first valve structure 44 includes a first spring 51, a first fixing member 52 and a first valve core 53. The first fixing member 52 is provided with a first sealing surface 431. The first spring 51 is connected to the first valve core 53 and the first tube body 43. The first spring 51 is used to drive the first valve core 53 to move outward from the first tube body 43 so that the first valve core 53 contacts the first sealing surface 431, thereby sealing the first tube body 43.

[0079] The second valve structure 46 includes a second spring 54, a second fixing member 55, and a second valve core 56. The second fixing member 55 is provided with a second sealing surface 451. The second spring 54 is connected to the second valve core 56 and the second tube 45. The second spring 54 is used to drive the second valve core 56 to move outward from the second tube 45 so that the second valve core 56 contacts the second sealing surface 451, thereby sealing the second tube 45.

[0080] In the assembled state, the first valve core 53 abuts against the second fixing member 55, the second valve core 56 abuts against the first fixing member 52, and the first valve core 53 moves toward the first spring 51. Figure 6 (Moves from center to left), the first valve core 53 separates from the first sealing surface 431, and the second valve core 56 moves toward the direction closer to the second spring 54. Figure 6(Move to the right from the center), the second valve core 56 separates from the second sealing surface 451, so that the first tube 43 and the second tube 45 are connected.

[0081] The first valve core 53 abuts against the second fixing member 55, and the second valve core 56 abuts against the first fixing member 52. The first spring 51 and the second spring 54 are compressed, so that a flow channel is formed between the first valve structure 44 and the second valve structure 46, and the coolant can flow in the flow channel to realize the connection between the first pipe body 43 and the second pipe body 45.

[0082] When the first valve core 53 is pushed by the first spring 51 and the second valve core 56 is pushed by the second spring 54, the first valve core 53 moves toward the first sealing surface 431. Figure 6 The second valve core 56 moves towards the second sealing surface 451 and then moves to the right, contacting the first sealing surface 431. Figure 6 (Moves from center to left) and contacts the second sealing surface 451, so that the first tube 43 and the second tube 45 are sealed, thereby preventing coolant leakage.

[0083] In some embodiments, a sealing element 57 is provided between the first valve core 53 and the first sealing surface 431, and a sealing element 57 is provided between the second valve core 56 and the second sealing surface 451.

[0084] The seal 57 can fill the gap between the first valve core 53 and the first fixing member 52, as well as the gap between the second valve core 56 and the second fixing member 55, so that when the first valve core 53 contacts the first sealing surface 431, the first tube body 43 is almost completely sealed, and when the second valve core 56 contacts the second sealing surface 451, the second tube body 45 is almost sealed, thereby preventing coolant leakage when the first connector 41 and the second connector 42 are separated.

[0085] Please refer to Figure 3 , Figure 6 and Figure 8 In the above embodiment, the cooling capacity distribution unit 22 further includes a locking structure 61, and a cooperating structure 62 is provided on the outer shell 21. The locking structure 61 and the cooperating structure 62 cooperate to prevent the cooling capacity distribution unit 22 from moving out of the cavity 211.

[0086] Understandably, after the first connector 41 and the second connector 42 are connected, the first spring 51 and the second spring 54 are in a compressed state, exerting an outward force on the first valve core 53 and the second valve core 56, preventing the first connector 41 and the second connector 42 from conducting. Therefore, an external force needs to be applied to the first sub-connector 31 to keep the first connector 41 and the second connector 42 in a conducting state.

[0087] The locking structure 61 and the cooperating structure 62 cooperate to prevent the cold distribution unit 22 from moving out of the cavity 211, so that the first connector 41 is continuously subjected to thrust, ensuring that the first connector 41 and the second connector 42 are connected.

[0088] Please refer to Figure 6 , Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the locking structure 61 in the locked state. Figure 9 This is a schematic diagram of the locking structure 61 in the unlocked state. In the above embodiment, the locking structure 61 includes a fixed base 71, a locking rod 72, and a snap-fit ​​structure 73. The fixed base 71 is connected to the cooling distribution unit 22, the locking rod 72 is hinged to the fixed base 71, and the snap-fit ​​structure 73 is disposed at the first end 721 of the locking rod 72. The mating structure 62 includes a locking hole 621 disposed on the outer casing 21.

[0089] When the locking structure 61 is in the locked state, the locking structure 73 engages with the fixing seat 71 to prevent the locking rod 72 from rotating, and the second end 722 of the locking rod 72 extends into the locking hole 621. When the locking structure 61 is in the unlocked state, the locking structure 73 disengages from the fixing seat 71, and the second end 722 of the locking rod 72 is located outside the locking hole 621.

[0090] The locking rod 72 is hinged to the fixing base 71, thereby connecting the locking rod 72 to the cooling capacity distribution unit 22. The mating structure 62 includes a locking hole 621 provided on the housing 21. The locking rod 72 and the locking hole 621 engage to fix the cooling capacity distribution unit 22 to the housing 21. A snap-fit ​​structure 73 is provided at the first end 721 of the locking rod 72. By controlling the snap-fit ​​structure 73, the rotation direction and rotation angle of the locking rod 72 can be controlled.

[0091] When the locking structure 61 is locked, the snap-fit ​​structure 73 snaps into the fixed seat 71, preventing the locking rod 72 from rotating. This causes the second end 722 of the locking rod 72 to extend into the locking hole 621, thereby fixing the cooling distribution unit 22 to the outer shell 21. At this time, the first connector 41 and the second connector 42 are connected. The first spring 51 is compressed and generates a thrust on the first valve core 53. The second spring 54 is compressed and generates a thrust on the second valve core 56, causing the first connector 41 and the second connector 42 to close, and the cooling distribution unit 22 moves out of the cavity 211.

[0092] Locking rod 72 engages with locking hole 621 to fix the position of cooling distribution unit 22 and prevent cooling distribution unit 22 from ( Figure 4 As shown) To cavity 211 ( Figure 4 (As shown) Move outward, thereby keeping the first spring 51 and the second spring 54 in a compressed state, and keeping the first connector 41 and the second connector 42 connected.

[0093] When the locking structure 61 is in the unlocked state, the snap-fit ​​structure 73 is disengaged from the fixed seat 71, and the second end 722 of the locking rod 72 is located outside the locking hole 621. At this time, the first valve core 53 is pushed by the first spring 51, and the second valve core 56 is pushed by the second spring 54, causing the first valve core 53 to move outward from the first tube 43 and the second valve core 56 to move outward from the second tube 45. The first connector 41 and the second connector 42 are cut off, making it convenient to pull out the cooling capacity distribution unit 22.

[0094] Please refer to Figure 9 and Figure 10 In the above embodiment, the snap-fit ​​structure 73 includes a snap-fit ​​rod 81, which is hinged to the first end 721. The snap-fit ​​end of the snap-fit ​​rod 81 is provided with a hook portion 82, and a fixing block 83 is provided on the fixing base 71. When the locking structure 61 is in the locked state, the hook portion 82 is hooked onto the fixing block 83.

[0095] The locking rod 81 is hinged to the first end 721, meaning that the locking rod 81 and the first end 721 of the locking rod 72 can be connected via a rotating shaft, allowing the locking rod 81 to rotate around the rotating shaft. The locking end of the locking rod 81 is provided with a hook portion 82, and the fixing base 71 is provided with a fixing block 83. Because the locking rod 81 can rotate, the hook portion 82 can also rotate. After the hook portion 82 rotates a certain angle, it can hook onto the fixing block 83, thereby fixing the angle and position of the locking rod 72.

[0096] In the above embodiment, the snap-fit ​​structure 73 further includes a first elastic element 74, which is connected to the fixed base 71 and the snap-fit ​​rod 81. The first elastic element 74 is used to prevent the snap-fit ​​rod 81 from rotating in the direction of disengaging the hook portion 82 from the fixed block 83.

[0097] It is understandable that the latching rod 81 is hinged to the first end 721. That is, when the latching rod 81 is pressed, the hook part 82 will rotate at a certain angle. At this time, the hook part 82 hooks onto the fixing block 83, and the first elastic element 74 will undergo elastic deformation, thereby generating a clamping force, so that the hook part 82 is firmly connected to the fixing block 83, preventing the hook part 82 from detaching from the fixing block 83 under its own weight.

[0098] Meanwhile, after the hook part 82 disengages from the fixing block 83, the first elastic element 74 will gradually return to its initial state, so that the relative position of the hook part 82 and the locking rod 81 returns to its initial state, ensuring that the hook part 82 can continue to be used.

[0099] Continue to refer to Figure 8 and Figure 9In the above embodiment, the locking structure 61 further includes a second elastic element 75, which is used to drive the locking rod 72 to rotate in the direction in which the second end 722 disengages from the locking hole 621.

[0100] Understandably, one end of the second elastic element 75 is connected to the locking rod 72, and the other end is connected to the fixed seat 71. When the locking structure 73 is engaged with the fixed seat 71, the position of the locking rod 72 is fixed, and the second elastic element 75 is stretched. When the locking structure 73 disengages from the fixed seat 71, the locking rod 72 can rotate, and the second elastic element 75 will return from its stretched state to its normal state, thus moving the second elastic element 75 in the contraction direction. The locking rod 72 is connected to the second elastic element 75 and moves with the second elastic element 75, so that the second end 722 of the locking rod 72 is located outside the locking hole 621.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
