Technical Field

[0002] A server cabinet is a special cabinet used to install hardware devices such as servers, network equipment, and storage devices in data centers and network centers.

[0003] At present, the heat dissipation device used for servers in server cabinets often adopts a liquid cooling device, which includes a cooler, a liquid cooling pipe and a pipeline pump arranged on the liquid cooling pipe. The pipeline pump drives the cold liquid to flow out from the water outlet of the liquid cooling pipe to the cooler, and after being cooled by the cooler, it flows into the water inlet of the liquid cooling pipe. In this way, by arranging the liquid cooling pipe in the server chassis and controlling the temperature and flow rate of the liquid cooling pipe, the temperature stability in the server chassis is ensured. However, the current liquid cooling device has low heat dissipation efficiency, high power consumption, and a single heat dissipation mode, resulting in the heat dissipation effect cannot meet the heat dissipation requirements of different types of servers inside the server cabinet. Summary of the invention

[0004] The purpose of the present invention is to provide a heat dissipation device and a server cabinet, which solves the problem that the heat dissipation effect of the current liquid cooling device cannot meet the heat dissipation requirements of different types of servers inside the server cabinet.

[0005] To achieve the above object, the present invention provides a heat dissipation device, comprising:

[0006] Liquid cooling module, the liquid cooling module includes a cold liquid tank, a heat absorbing component and a heat dissipating component. The cold liquid tank and the heat absorbing component are used to be arranged inside the cabinet, and the heat dissipating component is used to be arranged outside the cabinet. Both ends of the heat absorbing component are respectively connected to the cold liquid tank and the heat dissipating component. The heat dissipating component is connected to the cold liquid tank. The cold liquid in the cold liquid tank flows through the heat absorbing component to take away the heat inside the cabinet, and flows through the heat dissipating component to dissipate the heat.

[0007] The air cooling module includes a heat dissipation module, a motion module, a movable air permeable plate and a baffle. The heat dissipation module is arranged below the cold liquid tank. The motion module is connected to the movable air permeable plate and the baffle. The movable air permeable plate is used to block the air vents arranged in the cabinet. The baffle is used to block the heat dissipation vents arranged on the cabinet. After the motion module drives the movable air permeable plate and the baffle to open the air vents and the heat dissipation vents respectively, the heat dissipation module is used to introduce air outside the cabinet into the interior of the cabinet, and is also used to lead the air after heat exchange with the cold liquid tank out of the cabinet through the air vents and the heat dissipation vents.

[0008] In some aspects, the heat sink assembly includes:

[0009] The heat absorbing plate is used to absorb the heat generated by the heating components in the cabinet when they are working;

[0010] The heat absorbing coil is arranged on the heat absorbing plate in an S-shaped coil.

[0011] In other aspects, the heat dissipation assembly includes:

[0012] A heat dissipation pipe, one end of which is connected to the heat absorbing coil, and the other end is connected to the cold liquid tank. A circulating pump is provided on the heat dissipation pipe;

[0013] A plurality of heat dissipation fins are arranged on the heat dissipation pipe and are used to dissipate the heat in the heat dissipation pipe to the outside of the cabinet.

[0014] In other aspects, the heat dissipation component also includes a heat dissipation fan, which is arranged on the side of the heat dissipation fins away from the heat absorption component, and the heat dissipation fan is used to blow air to the heat dissipation fins and the heat dissipation pipes.

[0015] In other aspects, the motion module includes:

[0017] The telescopic pump is connected to the driving connecting rod and is used to drive the driving connecting rod to move relative to the cabinet.

[0018] In other aspects, a sliding rod is fixedly connected to one side of the baffle away from the transmission connecting rod, and the sliding rod is used to be slidably embedded in the cabinet. The baffle slides relative to the cabinet between a first position and a second position through the sliding rod, so that the baffle blocks the heat dissipation port in the first position and opens the heat dissipation port in the second position.

[0019] In other aspects, a bracket is provided above the cold liquid tank, the bracket is fixedly connected to a fixed air-permeable plate, the upper end of the fixed air-permeable plate is slidably connected to a movable air-permeable plate, the movable air-permeable plate is fixedly connected to a connecting cross bar, and one end of the connecting cross bar away from the movable air-permeable plate passes through the cabinet and is fixedly connected to the bottom end of the transmission connecting rod;

[0020] The fixed air permeable plate is provided with a plurality of first air permeable slots distributed at intervals, and the movable air permeable plate is provided with a plurality of second air permeable slots distributed at intervals. When the movable air permeable plate moves until the second air permeable slots are aligned with the corresponding first air permeable slots, the air below the fixed air permeable plate can flow into the top of the movable air permeable plate through the second air permeable slots and the first air permeable slots.

[0021] In other aspects, the air cooling module further includes a support positioning frame, the support positioning frame being used to be fixedly connected to the bottom end of the cabinet;

[0022] The heat dissipation module includes a servo motor and a heat dissipation fan. The top surface of the support and positioning frame is fixedly connected with the servo motor. The output end of the servo motor extends to the bottom of the support and positioning frame, and the output end of the servo motor is connected to the heat dissipation fan located below the support and positioning frame.

[0023] The heat dissipation device also includes a dustproof component, which is arranged below the heat dissipation fan and is used to prevent dust outside the cabinet from entering the space where the heat dissipation fan is located;

[0024] The dustproof assembly includes a dustproof mesh plate, a cleaning cross bar and a cleaning brush, wherein the dustproof mesh plate is fixedly connected to the bottom surface of the support and positioning frame, the output end of the servo motor is rotatably connected to the middle part of the dustproof mesh plate, the cleaning cross bar is fixedly connected to the output end of the servo motor, the cleaning cross bar is located on the side of the dustproof mesh plate away from the cooling fan, and a cleaning brush is fixedly connected to a side of the cleaning cross bar close to the dustproof mesh plate, the top surface of the cleaning brush is in contact with the bottom surface of the dustproof mesh plate, so that when the output end of the servo motor rotates, the cleaning brush is driven to rotate relative to the dustproof mesh plate, so that the cleaning brush cleans the dust on the dustproof mesh plate;

[0025] When the servo motor is turned on, the servo motor drives the cooling fan to rotate to introduce natural wind from outside the cabinet into the cabinet. After the natural wind enters the cabinet, it exchanges heat with the cold liquid tank and then flows out of the cabinet through the air vents and the heat dissipation ports, thereby completing the heat dissipation inside the cabinet. In addition, the output end of the servo motor drives the cleaning cross bar and the cleaning brush to clean the bottom surface of the dustproof screen to avoid clogging of the dustproof screen.

[0026] In other aspects, the heat dissipation device also includes a base, the top of the base is used to connect to the cabinet, the base and the dustproof screen form a accommodating cavity, and the accommodating cavity is used to accommodate the heat dissipation fan.

[0027] The present invention also provides a server cabinet, comprising any one of the above-mentioned heat dissipation devices.

[0028] With respect to the above background technology, the heat dissipation device provided in the embodiment of the present invention includes a liquid cooling module and an air cooling module. The liquid cooling module includes a cold liquid tank, a heat absorption component and a heat dissipation component. The cold liquid tank and the heat absorption component are used to be arranged inside the cabinet, and the heat dissipation component is used to be arranged outside the cabinet. The two ends of the heat absorption component are respectively connected to the cold liquid tank and the heat dissipation component. The heat dissipation component is connected to the cold liquid tank. The cold liquid in the cold liquid tank flows through the heat absorption component to take away the heat inside the cabinet, and flows through the heat dissipation component to dissipate the heat; the air cooling module includes a heat dissipation module, a motion module, a movable air permeable plate and a baffle. The heat dissipation module is arranged below the cold liquid tank. The motion module is connected to the movable air permeable plate and the baffle. The movable air permeable plate is used to block the air permeable port arranged in the cabinet. The baffle is used to block the heat dissipation port arranged on the cabinet. After the motion module drives the movable air permeable plate and the baffle to open the air permeable port and the heat dissipation port respectively, the heat dissipation module is used to introduce the air outside the cabinet into the cabinet, and is also used to lead the air after heat exchange with the cold liquid tank out of the cabinet through the air permeable port and the heat dissipation port in sequence.

[0029] It can be seen that in the first working mode, the liquid cooling module is turned on, and the cold liquid forms a liquid cooling cycle between the cold liquid tank, the heat absorbing component and the heat dissipation component. In this circulation mode, the cold liquid in the cold liquid tank flows through the heat absorbing component and the heat dissipation component successively. When the cold liquid flows through the heat absorbing component, it takes away the heat inside the cabinet absorbed by the heat absorbing component. When the cold liquid flows through the heat dissipation component, it dissipates the heat. Finally, the cold liquid flows back to the cold liquid tank, so that the heat inside the cabinet can be taken away by liquid cooling. In the second working mode, on the basis of keeping the liquid cooling module turned on, the air cooling module is further turned on. The natural wind outside the cabinet enters the cabinet and passes through the cold liquid tank. The temperature of the natural wind can be further reduced while passing through the cold liquid tank. The cold air passes through the air vent and is led out of the cabinet from the heat dissipation port. In this flow process, auxiliary heat dissipation inside the cabinet can be completed.

[0030] The heat dissipation device thus arranged has the following beneficial effects: the heat dissipation device provided by the embodiment of the present invention combines two heat dissipation modes, namely, liquid cooling and air cooling. In the first working mode, the liquid cooling module is turned on, and the cold liquid in the cold liquid tank flows successively through the heat absorption component and the heat dissipation component to bring out the heat inside the cabinet and dissipate it, thereby realizing heat dissipation inside the cabinet by liquid cooling. In the second working mode (especially after the temperature inside the cabinet continues to rise), the liquid cooling module and the air cooling module are turned on at the same time. On the basis of the aforementioned liquid cooling, natural wind outside the cabinet is further introduced to form cold wind after heat exchange with the cold liquid tank. The cold wind circulates inside the cabinet to realize further heat dissipation inside the cabinet. As a result, the server cabinet can apply two heat dissipation modes, namely, liquid cooling and liquid cooling + air cooling, and different heat dissipation modes can be used to cope with different working conditions inside the cabinet, thereby optimizing the overall heat dissipation effect and greatly improving the heat dissipation efficiency, so that the heat dissipation effect can meet the heat dissipation requirements of different types of servers inside the server cabinet, solving the problem that the heat dissipation effect of the current liquid cooling device cannot meet the heat dissipation requirements of different types of servers inside the server cabinet.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] It should be noted that the directional words such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.

[0049] See also Figure 1 and Figure 2 The heat dissipation device provided in the embodiment of the present invention includes a liquid cooling module 10 and an air cooling module 20.

[0050] The liquid cooling module 10 includes a cold liquid tank 11, a heat absorbing component 12 and a heat dissipation component 13. The cold liquid tank 11 and the heat absorbing component 12 are used to be arranged inside the cabinet 40, and the heat dissipation component 13 is used to be arranged outside the cabinet 40. The two ends of the heat absorbing component 12 are respectively connected to the cold liquid tank 11 and the heat dissipation component 13. The heat dissipation component 13 is connected to the cold liquid tank 11. The cold liquid in the cold liquid tank 11 flows through the heat absorbing component 12 to take away the heat inside the cabinet 40, and flows through the heat dissipation component 13 to dissipate the heat.

[0051] The air cooling module 20 includes a heat dissipation module 21, a motion module 22, a movable air permeable plate 23 and a baffle 24. The heat dissipation module 21 is arranged below the cold liquid tank 11. The motion module 22 connects the movable air permeable plate 23 and the baffle 24. The movable air permeable plate 23 is used to block the air vents arranged in the cabinet 40. The baffle 24 is used to block the heat dissipation port 41 arranged on the cabinet 40. After the motion module 22 drives the movable air permeable plate 23 and the baffle 24 to open the air vents and the heat dissipation port 41 respectively, the heat dissipation module 21 is used to introduce air outside the cabinet 40 into the interior of the cabinet 40, and is also used to lead the air after heat exchange with the cold liquid tank 11 out of the cabinet 40 through the air vents and the heat dissipation port 41 in turn.

[0052] It can be seen that in the first working mode, the liquid cooling module 10 is turned on, and the cold liquid forms a liquid cooling cycle between the cold liquid tank 11, the heat absorbing component 12 and the heat dissipation component 13. In this circulation mode, the cold liquid in the cold liquid tank 11 flows through the heat absorbing component 12 and the heat dissipation component 13 successively. When the cold liquid flows through the heat absorbing component 12, it takes away the heat inside the cabinet 40 absorbed by the heat absorbing component 12. When the cold liquid flows through the heat dissipation component 13, the heat is dissipated, and finally the cold liquid flows back to the cold liquid tank 11, so that the heat inside the cabinet 40 can be taken away by liquid cooling. In the second working mode, on the basis of keeping the liquid cooling module 10 turned on, the air cooling module 20 is further turned on, and the natural wind outside the cabinet 40 enters the cabinet 40 and passes through the cold liquid tank 11. The temperature of the natural wind can be further reduced while the natural wind passes through the cold liquid tank 11. The cold wind is led out of the cabinet 40 through the air vent and the heat dissipation port 41. In this flow process, the auxiliary heat dissipation inside the cabinet 40 can be completed.

[0053] The heat dissipation device thus arranged has the following beneficial effects: the heat dissipation device provided in the embodiment of the present invention combines two heat dissipation methods, namely liquid cooling and air cooling. In the first working mode, the liquid cooling module 10 is turned on, and the cold liquid in the cold liquid tank 11 flows successively through the heat absorption component 12 and the heat dissipation component 13 to bring out the heat inside the cabinet 40 and dissipate it, thereby realizing the heat dissipation inside the cabinet 40 by liquid cooling. In the second working mode (especially after the temperature inside the cabinet 40 continues to rise), the liquid cooling module 10 and the air cooling module 20 are turned on at the same time. On the basis of the aforementioned liquid cooling, natural wind outside the cabinet 40 is further introduced to form cold wind after heat exchange with the cold liquid tank 11. The cold wind circulates inside the cabinet 40 to realize further heat dissipation inside the cabinet 40. Therefore, the server cabinet can adopt two cooling modes: liquid cooling and liquid cooling + air cooling, and respond to different working conditions inside the cabinet 40 through different cooling modes, thereby optimizing the overall cooling effect and greatly improving the cooling efficiency, so that the cooling effect can meet the cooling requirements of different types of servers inside the server cabinet, solving the problem that the cooling effect of the current liquid cooling device cannot meet the cooling requirements of different types of servers inside the server cabinet.

[0054] In some embodiments, the heat absorption assembly 12 includes a heat absorption plate 121 and a heat absorption coil 122 .

[0055] Please also read Figure 3 , Figure 4 and Figure 5 The heat absorbing plate 121 is used to contact the heating component in the cabinet 40 to absorb the heat generated by the heating component in the cabinet 40 when it is working; the heat absorbing coil 122 is S-shaped and arranged on the heat absorbing plate 121, one end of the heat absorbing coil 122 is connected to the cold liquid tank 11, and the other end extends to the outside of the cabinet 40 to connect to the heat dissipation component 13, and the heat absorbing coil 122 is used to lead the cold liquid in the cold liquid tank 11 to the heat absorbing plate 121 to take away the heat of the heat absorbing plate 121.

[0056] In this embodiment, the overall structure of the heat absorbing plate 121 and the heat absorbing coil 122 is fixed in the internal space of the cabinet 40. For example, a refrigeration heat absorbing copper plate can be fixedly connected to the middle of the cabinet 40, and the surface of the refrigeration heat absorbing copper plate is S-shaped and fixedly arranged with circulating heat absorbing copper tubes.

[0057] Specifically, the refrigeration heat-absorbing copper plate can be fixedly connected to one side inner wall of the cabinet 40 by a detachable connection assembly (screw or bolt assembly), and the refrigeration heat-absorbing copper plate is arranged in a vertical posture inside the cabinet 40. Correspondingly, the circulating heat-absorbing copper tube is also arranged in a vertical posture on the surface of the refrigeration heat-absorbing copper plate close to the inner wall of the cabinet 40. In this way, the heat generated by the heating component (server) inside the cabinet 40 can be absorbed by the refrigeration heat-absorbing copper plate, and when the cold liquid in the cold liquid tank 11 passes into the circulating heat-absorbing copper tube, the heat of the refrigeration heat-absorbing copper plate can be transferred to the cold liquid through the circulating heat-absorbing copper tube, and the heat is taken out to the outside of the cabinet 40 as the cold liquid flows.

[0058] Furthermore, in order to improve the heat absorption efficiency, the circulating heat absorption copper tube should cover the surface of the refrigeration heat absorption copper plate as much as possible, so as to increase the contact area between the refrigeration heat absorption copper plate and the circulating heat absorption copper tube, thereby improving the heat transfer efficiency.

[0059] In some embodiments, the heat dissipation assembly 13 includes a heat dissipation pipe 131 and a plurality of heat dissipation fins 133 .

[0060] One end of the heat pipe 131 is connected to the heat absorbing coil 122, and the other end is connected to the cold liquid tank 11. A circulating pump 132 is provided on the heat pipe 131, and a plurality of heat dissipating fins 133 are provided on the heat pipe 131. Each heat dissipating fin 133 is used to dissipate the heat in the heat pipe 131 to the outside of the cabinet 40. Of course, the heat pipe 131 can be a circulating heat dissipation copper pipe.

[0061] Specifically, one end of the circulating heat-absorbing copper tube extends to the outside of the cabinet 40, the output end of the circulating heat-absorbing copper tube is fixedly connected to the circulating heat-dissipating copper tube, the middle of the circulating heat-dissipating copper tube is fixedly connected to a circulating pump 132, and the surface of the circulating heat-dissipating copper tube is fixedly connected to a plurality of heat-dissipating fins 133 in a linear array. Of course, the arrangement of the heat-dissipating fins 133 on the heat-dissipating tube 131 needs to comprehensively consider multiple factors such as the shape, arrangement, thickness, length and spacing of the fins to achieve the best heat dissipation effect.

[0062] It can be seen that the circulation pump 132 is used to provide power for the flow of cold liquid, so that the cold liquid circulates between the cold liquid tank 11-heat absorbing coil 122-heat dissipation pipe 131-cold liquid tank 11, and each heat dissipation fin 133 is combined with the heat dissipation pipe 131 to form a fin-tube radiator to dissipate the heat carried in the cold liquid through the heat dissipation pipe 131 and the heat dissipation fins 133 arranged outside the heat dissipation pipe 131.

[0063] Furthermore, the heat dissipation component 13 further includes a heat dissipation fan 134 . The heat dissipation fan 134 is disposed on a side of the heat dissipation fins 133 away from the heat absorption component 12 . The heat dissipation fan 134 is used to blow air toward the heat dissipation fins 133 and the heat dissipation pipes 131 .

[0064] It is understandable that a cooling fan 134 capable of actively dissipating heat is fixedly connected to the side of the cooling fin 133 away from the cabinet 40, and the cooling fan 134 is used to blow out cooling air, thereby accelerating the flow of air in the cooling fin 133 and improving the efficiency of the cooling fin 133 in dissipating heat.

[0065] It should be noted that the heat absorption component 12 composed of the heat absorption plate 121 and the heat absorption coil 122 is arranged inside the cabinet 40, and the heat dissipation component 13 composed of the heat dissipation pipe 131, multiple heat dissipation fins 133 and the heat dissipation fan 134 is arranged outside the cabinet 40. The heat absorption component 12 and the heat dissipation component 13 are separated by the side panel of the cabinet 40, and a heat dissipation connection is established between the heat absorption component 12 and the heat dissipation component 13 through the heat absorption coil 122 extending to the outside of the cabinet 40.

[0066] When in use, first turn on the circulation pump 132, and the circulation pump 132 sucks the cold liquid inside the cold liquid tank 11 through the circulating heat-absorbing copper tube. After passing through the refrigeration heat-absorbing copper plate, the heat inside the cabinet 40 absorbed by the refrigeration heat-absorbing copper plate and the circulating heat-absorbing copper tube can be brought out to the circulating heat-dissipating copper tube through the circulating heat-absorbing copper tube. When the cold liquid reaches the middle of the circulating heat-dissipating copper tube, the heat absorbed by the cold liquid inside the circulating heat-dissipating copper tube is converted through the heat dissipating fins 133, and then the heat is dissipated through the active heat dissipation cooling fan 134. After completion, the cold liquid returns to the inside of the cold liquid tank 11, thereby completing the circulation heat dissipation.

[0067] In some embodiments, the inner bottom of the cabinet 40 is fixedly connected with a plurality of plate-type cold liquid tanks 11 in a linear array, the input end of the circulating heat-absorbing copper tube is fixedly connected to the surface of the cold liquid tank 11, and the output end of the circulating heat-dissipating copper tube is fixedly connected to the surface of the cold liquid tank 11. The cold liquid tank 11 includes a plurality of plate-type water tanks, which are connected by a plurality of pipes, and a certain gap is reserved between any two adjacent plate-type water tanks to ensure that the external natural wind is cooled when flowing through the cold liquid tank 11.

[0068] In some embodiments, the motion module 22 includes a transmission connecting rod 221 and a telescopic pump 222 .

[0069] Please also read Figure 6 The transmission connecting rod 221 is used to be movably connected to the outer surface of the cabinet 40 to move relative to the cabinet 40. The transmission connecting rod 221 connects the movable air permeable plate 23 and the baffle 24; the telescopic pump 222 is connected to the transmission connecting rod 221, and the telescopic pump 222 is used to drive the transmission connecting rod 221 to move relative to the cabinet 40.

[0070] In this embodiment, the telescopic pump 222 is an electric telescopic pump, the fixed end of the telescopic pump 222 is fixedly connected to the top of the cabinet 40, the output end of the telescopic pump 222 is fixedly connected to a transmission connecting rod 221, and the side of the transmission connecting rod 221 close to the cabinet 40 is fixedly connected to a baffle 24 and a movable air permeable plate 23. In this way, under the telescopic power of the telescopic pump 222, the transmission connecting rod 221 moves outward relative to the cabinet 40 to drive the baffle 24 to move relative to the heat dissipation port 41 and the movable air permeable plate 23 to move relative to the fixed air permeable plate 26, thereby opening the circulation channel required for the natural wind outside the cabinet 40 to flow inside the cabinet 40.

[0071] To facilitate the movement of the baffle 24, a sliding rod 241 is fixedly connected to the side of the baffle 24 facing away from the transmission connecting rod 221. The sliding rod 241 is used to be slidably embedded in the cabinet 40. For example, a sliding rod 241 can be fixed at each of the four corners of the baffle 24. The baffle 24 slides relative to the cabinet 40 between a first position and a second position through the sliding rod 241, so that the baffle 24 blocks the heat dissipation port 41 when it is in the first position and opens the heat dissipation port 41 when it is in the second position.

[0072] It should be noted that the above-mentioned heat dissipation port 41 is opened on the side panel of the cabinet 40 away from the heat dissipation fan 134, and the heat dissipation port 41 is set at an upper position. At the same time, a heat dissipation window 42 located below the transmission connecting rod 221 is also opened on the side panel, and a corresponding heat dissipation window 42 is also opened on the side panel on the other side, so as to ensure the efficient dissipation of heat inside the cabinet 40.

[0073] When the baffle 24 is located at the initial position (i.e., the first position), the baffle 24 covers the surface of the heat dissipation port 41, thereby achieving the purpose of blocking the heat dissipation port 41, that is, the baffle 24 completely covers the heat dissipation port 41, and the heat dissipation port 41 cannot achieve air circulation at this time; when the baffle 24 is located at the target position (i.e., the second position), the baffle 24 maintains a preset distance from the heat dissipation port 41, and at this time, the heat dissipation port 41 is opened, so that the air inside the cabinet 40 can flow out to the outside of the cabinet 40, which is beneficial to the efficient dissipation of heat inside the cabinet 40.

[0074] In some embodiments, a bracket 25 (also called a sliding bracket) is provided above the cold liquid tank 11, and the bracket 25 is fixedly connected to a fixed air-permeable plate 26, and the upper end of the fixed air-permeable plate 26 is slidably connected to a movable air-permeable plate 23, and the movable air-permeable plate 23 is fixedly connected to a connecting cross bar 27, and the end of the connecting cross bar 27 away from the movable air-permeable plate 23 passes through the cabinet 40 and is fixedly connected to the bottom end of the transmission connecting rod 221.

[0075] In this embodiment, a plurality of first ventilation slots 261 are provided at intervals on the fixed ventilation plate 26, and a plurality of second ventilation slots 231 are provided at intervals on the movable ventilation plate 23. When the movable ventilation plate 23 moves until the second ventilation slots 231 are aligned with the corresponding first ventilation slots 261, the air below the fixed ventilation plate 26 can flow into the upper part of the movable ventilation plate 23 through the second ventilation slots 231 and the first ventilation slots 261.

[0076] It can be seen that, since the movable air permeable plate 23 can slide relative to the fixed air permeable plate 26, the air permeable opening formed by the first air permeable slot 261 and the second air permeable slot 231 can be switched from a closed state to an open state. Specifically, in the initial state, the transmission connecting rod 221 is attached to the outer wall of the cabinet 40. At this time, the first air permeable slot 261 on the fixed air permeable plate 26 and the second air permeable slot 231 on the movable air permeable plate 23 are staggered, and the first air permeable slot 261 on the fixed air permeable plate 26 and the second air permeable slot 231 on the movable air permeable plate 23 are both blocked, and the natural wind outside the cabinet 40 cannot pass through the air permeable slot; when the telescopic pump 222 drives the transmission connecting rod 221 to move outward, the movable air permeable plate 23 follows the transmission connecting rod 221 to move outward until the movable air permeable plate 23 moves to align with the second air permeable slot 231 and the corresponding first air permeable slot 261. At this time, the air permeable slot is open, and the air below the fixed air permeable plate 26 can flow into the top of the movable air permeable plate 23 through the second air permeable slot 231 and the first air permeable slot 261, thereby dissipating the heat of the server inside the cabinet 40.

[0077] In this way, when the temperature inside the cabinet 40 rises, the telescopic pump 222 is turned on, and the telescopic pump 222 pushes the transmission connecting rod 221 to move outward, thereby driving the baffle 24 and the connecting cross bar 27 to move. The movement of the baffle 24 stops blocking the heat dissipation port 41, and the movement of the connecting cross bar 27 can drive the movable air permeable plate 23 to move in the bracket 25 until the second air permeable slot 231 on the surface of the movable air permeable plate 23 is aligned with the first air permeable slot 261 of the fixed air permeable plate 26 up and down. At this time, the heat dissipation module 21 is turned on, and the heat dissipation module 21 introduces external natural wind into the cabinet 40. After the natural wind enters the cabinet 40, it passes through the middle part of the cold liquid tank 11. While passing through the cold liquid tank 11, the temperature of the natural wind can be further reduced. The wind enters the interior of the cabinet 40 through the fixed air permeable plate 26 and the movable air permeable plate 23 and is discharged through the heat dissipation port 41, thereby completing the auxiliary heat dissipation of the interior of the cabinet 40.

[0078] In some embodiments, the air cooling module 20 also includes a support positioning frame 28, which is used to be fixedly connected to the bottom end of the cabinet 40. The middle part of the support positioning frame 28 can be a cross-shaped structure. The support positioning frame 28 is used to provide fixed support for the heat dissipation module 21.

[0079] For details, please refer to Figure 7 and Figure 8 The heat dissipation module 21 includes a servo motor 211 and a heat dissipation fan 212. The servo motor 211 is fixedly connected to the top surface of the support and positioning frame 28. The output end of the servo motor 211 extends to the bottom of the support and positioning frame 28, and the output end of the servo motor 211 is connected to the heat dissipation fan 212 located below the support and positioning frame 28. Multiple blades of the heat dissipation fan 212 are installed in a ring array below the support and positioning frame 28.

[0080] In this way, when the servo motor 211 is turned on, the servo motor 211 drives the cooling fan 212 to rotate, so as to introduce natural wind outside the cabinet 40 into the interior of the cabinet 40. After the natural wind enters the interior of the cabinet 40, it exchanges heat with the cold liquid tank 11 and then flows out of the cabinet 40 through the air vent and the heat dissipation port 41, thereby completing the heat dissipation inside the cabinet 40.

[0081] Furthermore, the heat dissipation device further includes a dustproof component 30 , which is disposed below the heat dissipation fan 212 . The dustproof component 30 is used to prevent dust outside the cabinet 40 from entering the space where the heat dissipation fan 212 is located.

[0082] Specifically, the dustproof component 30 includes a dustproof mesh plate 31, a cleaning cross bar 32 and a cleaning brush 33, wherein the dustproof mesh plate 31 is fixedly connected to the bottom surface of the support positioning frame 28, the output end of the servo motor 211 is rotatably connected to the middle part of the dustproof mesh plate 31, the cleaning cross bar 32 is fixedly connected to the output end of the servo motor 211, the cleaning cross bar 32 is located on the side of the dustproof mesh plate 31 away from the cooling fan 212, and the cleaning brush 33 is fixedly connected to the side of the cleaning cross bar 32 close to the dustproof mesh plate 31, and the top surface of the cleaning brush 33 is in contact with the bottom surface of the dustproof mesh plate 31.

[0083] In this way, after the servo motor 211 is turned on, the output end of the servo motor 211 rotates to drive the cleaning brush 33 to rotate relative to the dustproof mesh plate 31, so that the cleaning brush 33 cleans the dust on the dustproof mesh plate 31.

[0084] That is to say, when the servo motor 211 is turned on, the servo motor 211 drives the cooling fan 212 to rotate so as to introduce natural wind from the outside of the cabinet 40 into the inside of the cabinet 40. After the natural wind enters the inside of the cabinet 40, it exchanges heat with the cold liquid tank 11 and then flows out of the cabinet 40 through the air vent and the heat dissipation port 41, thereby completing the heat dissipation inside the cabinet 40. In addition, the output end of the servo motor 211 drives the cleaning cross bar 32 and the cleaning brush 33 to clean the bottom surface of the dustproof mesh plate 31 to prevent the dustproof mesh plate 31 from being blocked.

[0085] In some embodiments, the heat dissipation device also includes a base 50, the top of the base 50 is used to connect to the cabinet 40, and the bottom of the base 50 is provided with a dustproof mesh plate 31. The base 50 and the dustproof mesh plate 31 form a accommodating cavity, and the accommodating cavity is used to accommodate the cooling fan 212.

[0086] In some embodiments, the heat dissipation device further includes a temperature detection module and a control module. The temperature detection module is disposed inside the cabinet 40, and is used to detect the temperature inside the cabinet 40 to achieve the purpose of monitoring the temperature inside the cabinet 40. The control module is connected to the temperature detection module, the circulation pump 132, the servo motor 211, and the telescopic pump 222 for communication, and is used to control the circulation pump 132, the servo motor 211, and the telescopic pump 222 to start and stop according to the temperature value detected by the temperature detection module.

[0087] In some embodiments, a temperature detection module is used to monitor the temperature inside the cabinet 40 in real time, and multiple temperature thresholds are set. When the temperature inside the cabinet 40 reaches these thresholds, the movement of the movable air permeable plate 23 and the baffle 24 is triggered. Specifically, a first temperature threshold and a second temperature threshold are set, and the second temperature threshold is greater than the first temperature threshold. When the temperature inside the cabinet 40 reaches the first temperature threshold, the temperature detection module transmits a temperature signal to the control module, and the control module sends a control signal to the telescopic pump 222, thereby driving the movable air permeable plate 23 to move relative to the fixed air permeable plate 26, and making the air port half open, so that on the basis of the operation of the liquid cooling module 10, by opening half of the air port, the external natural wind enters the cabinet 40 through the air port for air cooling and heat dissipation; when the temperature inside the cabinet 40 reaches the second temperature threshold, the temperature detection module transmits a temperature signal to the control module, and the control module sends a control signal to the telescopic pump 222, thereby driving the movable air permeable plate 23 to move relative to the fixed air permeable plate 26, and making the air port fully open, so that on the basis of the operation of the liquid cooling module 10, by fully opening the air port, the external natural wind enters the cabinet 40 through the air port for air cooling and heat dissipation.

[0088] In this way, by setting a temperature detection module in the cabinet 40, the temperature changes inside the cabinet 40 can be monitored in real time. The communication connection between the temperature detection module and the control module can realize automatic control, reduce manual intervention, and improve the convenience and accuracy of operation, thereby ensuring the safety and stability of the server operation inside the cabinet 40. The control module controls the opening and closing of the circulation pump 132, the servo motor 211, and the telescopic pump 222 according to the temperature value detected by the temperature detection module. In this way, the operation of the liquid cooling module 10 and the air cooling module 20 can be adjusted according to the actual heat dissipation requirements, thereby improving energy efficiency and cost-effectiveness.

[0089] To sum up, when in use, first turn on the circulation pump 132, and the circulation pump 132 sucks out the cold liquid inside the cold liquid tank 11 through the heat absorbing coil 122. After passing through the heat absorbing plate 121, the heat inside the cabinet 40 absorbed by the heat absorbing plate 121 and the heat absorbing coil 122 can be brought out to the heat dissipation pipe 131 through the heat absorbing coil 122. When the cold liquid reaches the middle of the heat dissipation pipe 131, the heat absorbed by the cold liquid inside the heat dissipation pipe 131 is converted through the heat dissipation fins 133, and then the heat is dissipated through the active heat dissipation fan 134. After completion, the cold liquid returns to the inside of the cold liquid tank 11, thereby completing the circulation heat dissipation.

[0090] When the temperature inside the cabinet 40 rises, the telescopic pump 222 is turned on, and the telescopic pump 222 pushes the transmission connecting rod 221 to move outward, thereby driving the baffle 24 and the connecting cross bar 27 to move. The movement of the baffle 24 stops blocking the heat dissipation port 41, and the movement of the connecting cross bar 27 can drive the movable air permeable plate 23 to move in the bracket 25 until the second air permeable notch 231 on the surface of the movable air permeable plate 23 is aligned with the first air permeable notch 261 of the fixed air permeable plate 26. At this time, the servo motor 211 is turned on, and the servo motor 211 drives the heat dissipation fan 2 12 rotates to introduce external natural wind into the cabinet 40. At the same time, the output end of the servo motor 211 drives the cleaning cross bar 32 and the cleaning brush 33 to clean the bottom surface of the dustproof mesh plate 31 to avoid clogging of the dustproof mesh plate 31. After the natural wind enters the cabinet 40, it passes through the middle part of the cold liquid tank 11. While passing through the cold liquid tank 11, the temperature of the natural wind can be further reduced. After the natural wind enters the cabinet 40 through the fixed air permeable plate 26 and the movable air permeable plate 23, it is discharged through the heat dissipation port 41, thereby completing the auxiliary heat dissipation of the interior of the cabinet 40.

[0091] A server cabinet provided by the present invention includes a cabinet body 40 and also includes the heat dissipation device described in the above specific embodiment. The heat dissipation device is installed in the cabinet body 40 and is used to dissipate heat inside the cabinet body 40, thereby ensuring that the server inside the cabinet body 40 is in a stable working state. Other parts of the server cabinet can refer to related technologies and will not be expanded in this article.

[0092] The server cabinet using the above-mentioned heat dissipation device combines the two heat dissipation methods of liquid cooling and air cooling. In the first working mode, the liquid cooling module 10 is turned on, and the cold liquid in the cold liquid tank 11 flows through the heat absorption component 12 and the heat dissipation component 13 in succession to bring out the heat inside the cabinet 40 and dissipate it, thereby realizing the heat dissipation of the inside of the cabinet 40 by liquid cooling. In the second working mode (especially when the temperature inside the cabinet 40 continues to rise), the liquid cooling module 10 and the air cooling module 20 are turned on at the same time. On the basis of the above-mentioned liquid cooling, natural wind outside the cabinet 40 is further introduced to form cold wind after heat exchange with the cold liquid tank 11. The cold wind circulates inside the cabinet 40 to achieve further heat dissipation inside the cabinet 40.

[0093] Therefore, the server cabinet can adopt two cooling modes: liquid cooling and liquid cooling + air cooling, and respond to different working conditions inside the cabinet 40 through different cooling modes, thereby optimizing the overall cooling effect and greatly improving the cooling efficiency, so that the cooling effect can meet the cooling requirements of different types of servers inside the server cabinet, solving the problem that the cooling effect of the current liquid cooling device cannot meet the cooling requirements of different types of servers inside the server cabinet.

[0094] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

The description of the above embodiments is only used to help understand the scheme of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the present invention.
