Technical Field

[0001] This invention relates to the field of server rack technology, and in particular to server racks and heat dissipation systems. Background Technology

[0002] A server is a device that provides computing or application services. Currently, servers are all placed in server racks.

[0003] In existing technology, server racks serve to support and install servers. Server racks are equipped with ventilation holes, and the ventilation holes, together with the air conditioning in the computer room, reduce the high temperature generated by the servers when they are working inside the server rack.

[0004] However, the above method, which simply changes the ambient temperature of the computer room to reduce the high temperature generated by the servers when they are working, will limit the heat dissipation effect on the servers inside the server rack. Summary of the Invention

[0005] The purpose of this invention is to provide a server rack and a heat dissipation system to solve the technical problem that the heat dissipation effect of servers inside server racks is limited in the prior art. The specific technical solution is as follows:

[0006] In a first aspect of the present invention, a server rack is provided, including a rack body, wherein a cooling fan and a cooling component are disposed within the rack body, wherein the air blown out from the exhaust side of the cooling fan is used to dissipate heat from the server inside the rack body, and the cooling component is located on the intake side of the cooling fan.

[0007] The cooling component includes an inlet pipe and a drain pipe. The inlet pipe is used to introduce low-temperature coolant. The cooling component is used to cool the air intake side of the cooling fan by means of the low-temperature coolant and heat exchange. The drain pipe is used to discharge high-temperature coolant. The high-temperature coolant is stored in a cooling tank and cooled into low-temperature coolant under natural cooling in a low-temperature environment.

[0008] Optionally, the cooling fan is driven to rotate by a connecting shaft, which is connected to the cooling assembly via a clutch component. The clutch component is used to connect the cooling assembly to the connecting shaft and also to disconnect the cooling assembly from the connecting shaft. When the cooling assembly is connected to the connecting shaft, the low-temperature coolant is introduced into the cooling assembly through the inlet pipe to cool the air intake side of the cooling fan.

[0009] Optionally, the cooling assembly includes a cooling component connected to the clutch component. The cooling component includes a mounting cylinder located on the air inlet side of the cooling fan, a hollow tube disposed in the mounting cylinder, a plurality of liquid-throwing pipes connected to the hollow tube, and a drain pipe connected to the mounting cylinder. When the cooling assembly is connected to the connecting shaft, the hollow tube rotates with the rotation of the connecting shaft.

[0010] The mounting cylinder has a cooling cavity, and multiple liquid-throwing pipes are located in the cooling cavity. The drain pipe is connected to the cooling cavity. The hollow tube is used to introduce the low-temperature coolant. The liquid-throwing pipes are used to throw the low-temperature coolant onto the inner wall of the mounting cylinder when the hollow tube rotates. The low-temperature coolant on the inner wall of the mounting cylinder is used to exchange heat with the outer side of the mounting cylinder, thereby cooling the air intake side of the cooling fan.

[0011] Optionally, the cooling assembly further includes a liquid inlet component connected to the cooling member, the liquid inlet component being used to introduce the low-temperature coolant into the hollow tube in the cooling member;

[0012] The liquid inlet component includes a pump cylinder connected to the mounting cylinder, a liquid inlet pipe connected to the end of the pump cylinder away from the mounting cylinder, a pump screw disposed inside the pump cylinder, and a connecting frame connected to the pump screw.

[0013] The pump cylinder has a pump chamber, which is isolated from the cooling chamber. The pump screw and the connecting frame are located in the pump chamber. The liquid inlet pipe is connected to the pump chamber and is used to introduce the low-temperature coolant into the pump chamber.

[0014] The connecting frame is also connected to the hollow tube. One end of the hollow tube near the pump cylinder extends into the pump cavity. The connecting frame rotates with the rotation of the hollow tube, and the pump screw rotates with the rotation of the connecting frame. When the pump screw rotates, it is used to guide the low-temperature coolant in the pump cavity into the hollow tube.

[0015] Optionally, the inner wall of the mounting cylinder is provided with a plurality of inner heat exchange fins, and the outer wall of the mounting cylinder is provided with a plurality of outer heat exchange fins. The liquid-throwing pipe is used to throw the low-temperature coolant onto the inner wall of the mounting cylinder and the plurality of inner heat exchange fins when the hollow tube rotates. The low-temperature coolant located on the inner wall of the mounting cylinder and the inner heat exchange fins is used to exchange heat with the plurality of outer heat exchange fins, thereby cooling the air intake side of the cooling fan.

[0016] Optionally, the cabinet body is provided with a first mounting cavity and a second mounting cavity connected to the first mounting cavity, the cooling fan is located in the first mounting cavity, the cooling component is located in the second mounting cavity, and the end of the second mounting cavity away from the first mounting cavity is connected to the outside of the cabinet body.

[0017] Optionally, the cabinet body is further provided with a first control module connected to the clutch component. The first control module is used to control the clutch component to connect the connecting shaft and the cooling component when the temperature on the outside of the cabinet body is greater than or equal to a first preset value.

[0018] The first control module is also used to control the clutch component to disconnect the cooling component from the connecting shaft when the temperature on the outside of the cabinet body is lower than the first preset value.

[0019] Optionally, the cabinet body is provided with a flow cavity, which is connected to the first mounting cavity. The flow cavity is connected to a blower pipe, which faces the server. The air blown out by the exhaust side of the cooling fan flows to the server through the flow cavity and the blower pipe to dissipate heat from the server.

[0020] In a second aspect of the present invention, a heat dissipation system is also provided, the heat dissipation system comprising at least one server rack as described in any of the preceding claims.

[0021] Optionally, it also includes a cooling tank and a storage tank connected to the cooling tank. The cooling tank is connected to a drain pipe in the server rack. The high-temperature coolant discharged from the drain pipe is stored in the cooling tank and cooled to low-temperature coolant under natural cooling in a low-temperature environment.

[0022] The storage tank is used to store the cryogenic coolant, and the storage tank is connected to the inlet pipe in the server rack. The storage tank is used to supply the cryogenic coolant to the inlet pipe.

[0023] Optionally, the cooling tank and the storage tank are connected by a first connecting pipe, and a solenoid valve is provided on the first connecting pipe;

[0024] The heat dissipation system also includes a second control module, which is electrically connected to the solenoid valve. The second control module is used to control the solenoid valve to open when the high-temperature coolant in the cooling tank is cooled to the low-temperature coolant, so that the low-temperature coolant in the cooling tank flows into the storage tank.

[0025] In this embodiment of the invention, the air blown out from the exhaust side of the cooling fan can dissipate heat and cool the server inside the server rack, achieving air-cooled cooling of the server. When the ambient temperature of the server rack is high, a cooling component can work in conjunction with the cooling fan to dissipate heat and cool the server. The cooling component can utilize low-temperature coolant and employ heat exchange to cool the intake side of the cooling fan, thereby improving the heat dissipation and cooling effect on the server. In this embodiment of the invention, both the cooling fan and the cooling component are located inside the server rack, allowing them to directly act on the server inside the rack, thus ensuring the heat dissipation and cooling effect on the server. This solves the technical problem in the prior art where simply changing the ambient temperature of the server room to reduce the high temperature generated by the server during operation limits the heat dissipation effect on the server inside the rack. Furthermore, this embodiment of the invention can utilize a low-temperature environment to naturally cool the high-temperature coolant to a low-temperature coolant, thereby reducing energy consumption.

Detailed Implementation

[0032] The technical solutions of the present invention will now be described with reference to the accompanying drawings in the embodiments of the present invention.

[0033] The embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. The invention is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0034] A server is a device that provides computing services. Because servers need to respond to and process service requests, they generally need to have the ability to undertake and guarantee services. Currently, servers are all housed in server racks.

[0035] In existing technologies, server racks only serve to support and install servers, as well as install modules, enclosures, electronic components, devices, and mechanical parts and components. Server racks themselves do not have temperature regulation capabilities. Typically, the high temperatures generated by servers during operation are reduced by altering the ambient temperature of the server room, such as through air conditioning, combined with the ventilation of the server rack. However, simply reducing the high temperatures generated by servers through changing the ambient temperature and ventilation has limitations in its heat dissipation effect. For example, in high summer temperatures, relying solely on ambient cooling is ineffective; furthermore, since air conditioning needs to cool the entire server room, this significantly increases energy consumption.

[0036] To address the aforementioned problems, in a first aspect, embodiments of the present invention provide a server rack. A server rack is a freestanding or self-supporting enclosure for housing electrical or electronic equipment, specifically for housing servers. The server rack mentioned above will be described in detail below.

[0037] Reference Figures 1 to 3 The server rack includes a rack body 10, which contains a cooling fan 20 and a cooling component 30. The air blown out from the exhaust side of the cooling fan 20 is used to dissipate heat from the server 60 inside the rack body 10. The cooling component 30 is located on the intake side of the cooling fan 20. The cooling component 30 includes an inlet pipe 324 and a drain pipe 314. The inlet pipe 324 is used to introduce low-temperature coolant. The cooling component 30 is used to cool the intake side of the cooling fan 20 by using the low-temperature coolant and heat exchange. The drain pipe 314 is used to discharge high-temperature coolant. The high-temperature coolant is stored in a cooling tank 70 and cooled to low-temperature coolant under natural cooling in a low-temperature environment.

[0038] Specifically, server 60 is placed inside rack 10. Cooling fan 20 can be an axial fan. Low-temperature coolant refers to coolant with a temperature less than or equal to a second preset value, and high-temperature coolant refers to coolant with a temperature greater than the second preset value. The coolant can be a liquid with high specific heat capacity, such as water or ethylene glycol aqueous solution, and has the advantage of strong heat carrying capacity. The second preset value can be set according to actual needs, such as any value within the range of 10-15 degrees Celsius. After the high-temperature coolant is stored in cooling tank 70, it can be naturally cooled to low-temperature coolant by utilizing a low-temperature environment, such as the low temperature at night. After cooling, the low-temperature coolant is recycled back to the cooling component 30. A low-temperature environment refers to an environment with a temperature less than or equal to a third preset value. The third preset value can be equal to or less than the second preset value.

[0039] The air blown out by the exhaust side of the cooling fan 20 can cool the server 60 inside the rack body 10. The cooling fan 20 alone can achieve air cooling of the server 60. When the ambient temperature of the server rack is high, such as when the ambient temperature is greater than or equal to a first preset value, the cooling component 30 can work in conjunction with the cooling fan 20 to cool the server 60. The cooling component 30 uses low-temperature coolant and heat exchange to cool the intake side of the cooling fan 20, thus ensuring that the air blown out by the exhaust side of the cooling fan 20 is cool. The first preset value can be set according to actual needs, such as any value within the range of 30 degrees Celsius to 40 degrees Celsius.

[0040] Reference Figure 4 The inlet pipe 324 is used to connect to the storage tank 80, which stores cryogenic coolant and supplies cryogenic coolant to the inlet pipe 324. The storage tank 80 stores cryogenic coolant in a capacity sufficient to meet the daytime operating needs of the cooling component 30. During the day, the high-temperature coolant discharged from the cooling component 30 is stored in the cooling tank 70. At night, when temperatures are lower, the high-temperature coolant stored in the cooling tank 70 is cooled to cryogenic coolant and flows into the storage tank 80 for storage. The storage tank 80 is designed with an insulated structure and uses insulating materials; for example, it can be designed with a double-layered vacuum structure and made of materials such as stainless steel or glass. The storage tank 80 can be placed outdoors to take full advantage of the low-temperature environment at night.

[0041] A server is a device that provides computing or application services. Servers possess high-speed CPU processing power and the characteristic of reliable operation over long periods. Server deployment and use require server racks, but conventional server racks have some drawbacks. Existing technologies typically rely on environmental cooling, but this is limited in effectiveness when summer air temperatures are high. In regions with significant diurnal temperature variations, daytime temperatures can reach over 40 degrees Celsius, while nighttime temperatures are much lower, at 10, 20, or even lower. Therefore, a technical solution that utilizes the lower nighttime temperatures to promote daytime server cooling is feasible. The server rack provided in this invention is specifically applied in regions with significant diurnal temperature variations.

[0042] In this embodiment of the invention, the air blown out from the exhaust side of the cooling fan 20 can dissipate heat and cool the server 60 inside the rack body 10, achieving air-cooled cooling of the server 60. When the ambient temperature of the server rack is high, the cooling component 30 can work in conjunction with the cooling fan 20 to dissipate heat and cool the server 60. The cooling component 30 can use low-temperature coolant and employ heat exchange to cool the intake side of the cooling fan 20, thereby improving the heat dissipation and cooling effect on the server 60. In this embodiment of the invention, both the cooling fan 20 and the cooling component 30 are located inside the rack body 10, and can directly act on the server 60 inside the rack body 10, thus ensuring the heat dissipation and cooling effect on the server 60. This solves the technical problem in the prior art where simply changing the ambient temperature of the computer room to reduce the high temperature generated by the server during operation limits the heat dissipation effect on the server inside the rack. Furthermore, this embodiment of the invention can utilize a low-temperature environment to naturally cool the high-temperature coolant to a low-temperature coolant, thereby reducing energy consumption. In addition, the cooling fan 20 and the cooling component 30 only need to cool the server 60 inside the rack body 10, without having to cool the entire environment where the server rack is located, thereby reducing energy consumption.

[0043] Reference Figure 1 The cooling fan 20 is driven to rotate by the connecting shaft 41. The connecting shaft 41 is connected to the cooling assembly 30 through the clutch component 50. The clutch component 50 is used to connect the cooling assembly 30 and the connecting shaft 41. The clutch component 50 is also used to disconnect the cooling assembly 30 from the connecting shaft 41. When the cooling assembly 30 is connected to the connecting shaft 41, the low-temperature coolant is introduced into the cooling assembly 30 through the inlet pipe 324 to cool the air intake side of the cooling fan 20.

[0044] Specifically, the rack body 10 is also equipped with a power motor 40. The output shaft of the power motor 40 is connected to the connecting shaft 41. The power motor 40 is used to drive the connecting shaft 41 to rotate. When the connecting shaft 41 rotates, it drives the cooling fan 20 to rotate. At this time, the exhaust side of the cooling fan 20 blows air to cool down the server 60 inside the rack body 10.

[0045] The clutch component 50 can be an electromagnetic clutch. When the electromagnetic clutch is engaged, connecting the cooling component 30 to the connecting shaft 41, the cooling component 30 operates, and low-temperature coolant is introduced into the cooling component 30 through the inlet pipe 324 to cool the air intake side of the cooling fan 20. When the electromagnetic clutch is disengaged, disconnecting the cooling component 30 from the connecting shaft 41, the cooling component 30 does not operate, and cooling is achieved solely through the cooling fan 20. In this embodiment of the invention, the clutch component 50 allows the connection between the cooling component 30 and the connecting shaft 41 to be disconnected at low temperatures, thereby enabling cooling to be achieved solely through the cooling fan 20 and reducing energy consumption.

[0046] In other embodiments, the cooling component 30 may be driven by a separate motor.

[0047] Reference Figure 1 The cooling assembly 30 includes a cooling component 31 connected to the clutch component 50. The cooling component 31 includes a mounting cylinder 311 located on the air inlet side of the cooling fan 20, a hollow tube 312 disposed inside the mounting cylinder 311, a plurality of liquid-throwing pipes 313 connected to the hollow tube 312, and a drain pipe 314 connected to the mounting cylinder 311. When the cooling assembly 30 is connected to the connecting shaft 41, the hollow tube 312 rotates with the rotation of the connecting shaft 41. The mounting cylinder 311 has a cooling function. The cavity 3111 and multiple liquid-throwing pipes 313 are all located inside the cooling cavity 3111. The drain pipe 314 is connected to the cooling cavity 3111. The hollow pipe 312 is used to introduce low-temperature coolant. The liquid-throwing pipes 313 are used to throw the low-temperature coolant onto the inner wall of the mounting cylinder 311 when the hollow pipe 312 rotates. The low-temperature coolant on the inner wall of the mounting cylinder 311 is used to exchange heat with the outside of the mounting cylinder 311, thereby cooling the air intake side of the cooling fan 20.

[0048] Specifically, refer to Figure 2The cross-section of the mounting cylinder 311 can be circular. The interior of the hollow tube 312 is hollow to allow the introduction of cryogenic coolant. The mounting cylinder 311 is fixed, and the clutch component 50 can be indirectly connected to the hollow tube 312. When the connecting shaft 41 rotates, the rotation of the connecting shaft 41 can be transmitted to the hollow tube 312 through the clutch component 50, thereby causing the hollow tube 312 to rotate. Multiple liquid-throwing pipes 313 can be spaced apart along the length of the hollow tube 312. When the hollow tube 312 rotates, the multiple liquid-throwing pipes 313 throw the cryogenic coolant inside the hollow tube 312 onto the inner wall of the mounting cylinder 311. After exchanging heat with the outside of the mounting cylinder 311, the cryogenic coolant on the inner wall of the mounting cylinder 311 absorbs heat and becomes a high-temperature coolant, which is then discharged from the drain pipe 314. In this embodiment of the invention, by setting up the hollow tube 312 and the liquid-throwing tube 313, the low-temperature coolant can be directly thrown onto the inner wall of the mounting cylinder 311 by the rotation of the connecting shaft 41, thereby exchanging heat with the outer side of the mounting cylinder 311, and thus cooling the air intake side of the cooling fan 20.

[0049] Reference Figure 1 and Figure 3 The cooling component 30 also includes a liquid inlet component 32 connected to the cooling component 31. The liquid inlet component 32 is used to introduce low-temperature coolant into the hollow tube 312 in the cooling component 31. The liquid inlet component 32 includes a water pump cylinder 321 connected to the mounting cylinder 311, a liquid inlet pipe 324 connected to the end of the water pump cylinder 321 away from the mounting cylinder 311, a water pump screw 322 disposed in the water pump cylinder 321, and a connecting frame 323 connected to the water pump screw 322.

[0050] The pump cylinder 321 has a pump chamber 3211, which is isolated from the cooling chamber 3111. The pump screw 322 and the connecting frame 323 are located inside the pump chamber 3211. The liquid inlet pipe 324 is connected to the pump chamber 3211 and is used to introduce low-temperature coolant into the pump chamber 3211. The connecting frame 323 is also connected to the hollow tube 312. One end of the hollow tube 312 near the pump cylinder 321 extends into the pump chamber 3211. The connecting frame 323 rotates with the rotation of the hollow tube 312. The pump screw 322 rotates with the rotation of the connecting frame 323. When the pump screw 322 rotates, it is used to guide the low-temperature coolant in the pump chamber 3211 into the hollow tube 312.

[0051] Specifically, the pumping chamber 3211 and the cooling chamber 3111 are not connected. The connecting frame 323 can be a hollow rectangular frame structure. The pumping screw 322 is used to pump the cryogenic coolant in the storage tank 80 into the inlet pipe 324 through the second connecting pipe 92, and then into the pumping chamber 3211. When the cooling assembly 30 is connected to the connecting shaft 41, the rotation of the connecting shaft 41 is first transmitted to the hollow tube 312 through the clutch component 50, thereby causing the hollow tube 312 to rotate. The rotation of the hollow tube 312 will first drive the connecting frame 323 to rotate, thereby driving the pumping screw 322 to rotate. Then, the cryogenic coolant is pumped from the storage tank 80 into the inlet pipe 324 through the second connecting pipe 92, and then into the pumping chamber 3211. The rotation of the pumping screw 322 guides the cryogenic coolant in the pumping chamber 3211 into the hollow tube 312. In this embodiment of the invention, the pump screw 322 can pump water by rotating the connecting shaft 41 without the need for an additional drive mechanism, and the structure is simple.

[0052] Reference Figure 1 and Figure 2 The inner wall of the mounting cylinder 311 is provided with multiple inner heat exchange fins 3112, and the outer wall of the mounting cylinder 311 is provided with multiple outer heat exchange fins 3113. The liquid-throwing pipe 313 is used to throw low-temperature coolant onto the inner wall of the mounting cylinder 311 and the multiple inner heat exchange fins 3112 when the hollow tube 312 rotates. The low-temperature coolant on the inner wall of the mounting cylinder 311 and the inner heat exchange fins 3112 is used to exchange heat with the multiple outer heat exchange fins 3113, thereby cooling the air intake side of the cooling fan 20.

[0053] Specifically, multiple inner heat exchange fins 3112 and multiple outer heat exchange fins 3113 can be distributed at intervals along the circumference of the mounting cylinder 311. In this embodiment of the invention, the arrangement of multiple inner heat exchange fins 3112 and multiple outer heat exchange fins 3113 improves the heat exchange effect, thereby improving the heat dissipation effect.

[0054] Reference Figure 1 The cabinet body 10 is provided with a first mounting cavity 11 and a second mounting cavity 12 connected to the first mounting cavity 11. The cooling fan 20 is located in the first mounting cavity 11, and the cooling component 30 is located in the second mounting cavity 12. The end of the second mounting cavity 12 away from the first mounting cavity 11 is connected to the outside of the cabinet body 10.

[0055] Specifically, both the first mounting cavity 11 and the second mounting cavity 12 are located at the lower part of the cabinet body 10. The second mounting cavity 12 is located on the air intake side of the cooling fan 20, and the mounting cylinder 311 is located inside the second mounting cavity 12. When the cooling fan 20 is working, it draws air from the outside of the cabinet body 10 through the second mounting cavity 12. When the cooling component 30 is connected to the connecting shaft 41, the hollow tube 312 rotates, and the liquid-throwing tube 313 throws the low-temperature coolant onto the inner wall of the mounting cylinder 311 and onto the multiple inner heat exchange fins 3112, so that the low-temperature coolant exchanges heat with the multiple outer heat exchange fins 3113, thereby reducing the temperature of the second mounting cavity 12 and thus cooling the air intake side of the cooling fan 20.

[0056] The rack body 10 can have multiple ventilation holes, which connect the second mounting cavity 12 to the outside of the rack body 10. Filters can be installed at these ventilation holes to filter dust, preventing external dust from being drawn into the rack body 10 by the cooling fan 20, thus ensuring a cleaner interior. In this embodiment, the connection between the second mounting cavity 12 and the outside of the rack body 10 facilitates continuous airflow from the cooling fan 20.

[0057] The cabinet body 10 is also equipped with a first control module connected to the clutch component 50. The first control module is used to control the clutch component 50 to connect the cooling component 30 and the connecting shaft 41 when the temperature on the outside of the cabinet body 10 is greater than or equal to a first preset value; the first control module is also used to control the clutch component 50 to disconnect the cooling component 30 and the connecting shaft 41 when the temperature on the outside of the cabinet body 10 is less than the first preset value.

[0058] Specifically, the first preset value can be set according to actual needs, such as any value within the range of 30-40 degrees Celsius. A first temperature sensor can be installed on the outside of the cabinet body 10 to monitor the temperature on the outside of the cabinet body 10. The first control module is also electrically connected to the first temperature sensor. The clutch component 50 is an electromagnetic clutch, and the first control module is electrically connected to the electromagnetic clutch. The first control module obtains the temperature on the outside of the cabinet body 10 through the first temperature sensor and controls the electromagnetic clutch according to the temperature on the outside of the cabinet body 10. In this embodiment of the invention, through the setting of the first control module, automatic control of the clutch component 50 can be realized, so that when the temperature is high, the connecting shaft 41 is automatically connected to the cooling component 30, and when the temperature is low, the cooling component 30 is automatically disconnected from the connecting shaft 41.

[0059] The first control module can also be electrically connected to the power motor 40, enabling it to control the motor 40. Specifically, the first control module can control the power motor 40 based on the temperature outside the server rack 10. For example, when the temperature outside the server rack 10 is less than or equal to a fourth preset value, the power motor 40 will stop operating; when the temperature outside the server rack 10 is greater than the fourth preset value, the power motor 40 will operate. The fourth preset value can be set according to actual needs, such as any value within the range of 15-20 degrees Celsius. When the power motor 40 stops operating, the cooling fan 20 does not rotate, allowing the server rack to dissipate heat naturally through ventilation.

[0060] Reference Figure 1 The cabinet body 10 is provided with a flow cavity 13, which is connected to the first mounting cavity 11. The flow cavity 13 is connected to a blower pipe 14, which faces the server 60. The air blown out by the exhaust side of the cooling fan 20 flows to the server 60 through the flow cavity 13 and the blower pipe 14 to dissipate heat from the server 60.

[0061] Specifically, the flow cavity 13 is connected to multiple air ducts 41. For any server 60 within the rack body 10, there are two air ducts 41 on each side. The number of air ducts 41 is twice the number of servers 60 that the rack body 10 can accommodate. The air blown from the exhaust side of the cooling fan 20 first flows into the flow cavity 13, then through the flow cavity 13 to the multiple air ducts 14, and finally blows towards both sides of the server 60. In this embodiment of the invention, the arrangement of the air ducts 14 ensures that the air blown from the exhaust side of the cooling fan 20 can ultimately reach the server 60, thereby improving the heat dissipation and cooling effect on the server 60.

[0062] Reference Figure 1 A rotating door 15 is rotatably connected to the rack body 10, and the rotating door 15 is located on the upper part of the rack body 10. A flow opening is provided on the rack body 10, and the flow opening is connected to the end of the flow cavity 13 away from the cooling fan 20. The rotating door 15 is specifically located at the flow opening. The rotating door 15 is used to connect the flow cavity 13 to the outside of the rack body 10. When the rotating door 15 is open, the flow cavity 13 is connected to the outside of the rack body 10; when the rotating door 15 is closed, the rotating door 15 completely covers the flow opening, and the flow cavity 13 is not connected to the outside of the rack body 10.

[0063] The rotating door 15 is made of a low-density material. The rotating door 15 is designed so that when the cooling fan 20 is rotating, the air blown out by the exhaust side of the cooling fan 20 flows through the flow cavity 13 to the rotating door 15, which can push the rotating door 15 open, so that the air blown out by the exhaust side of the cooling fan 20 can finally flow to the outside of the cabinet body 10.

[0064] When the cooling fan 20 is not running for an extended period, the rotating door 15 can be locked to ensure the server rack's dustproof performance. A filter can be installed at the airflow opening to filter dust, effectively keeping the inside of the rack 10 clean.

[0065] Secondly, referring to Figure 4 The present invention provides a heat dissipation system, which includes at least one server rack according to any one of the first aspects.

[0066] Specifically, the heat dissipation system includes at least one server rack, which includes a rack body 10. The rack body 10 is equipped with a cooling fan 20 and a cooling component 30. The air blown out from the exhaust side of the cooling fan 20 is used to dissipate heat from the server 60 inside the rack body 10. The cooling component 30 is located on the intake side of the cooling fan 20. The cooling component 30 includes an inlet pipe 324 and a drain pipe 314. The inlet pipe 324 is used to introduce low-temperature coolant. The cooling component 30 is used to cool the intake side of the cooling fan 20 by using the low-temperature coolant and heat exchange. The drain pipe 314 is used to discharge high-temperature coolant. The high-temperature coolant is stored in a cooling tank 70 and cooled to low-temperature coolant under natural cooling in a low-temperature environment.

[0067] In this embodiment of the invention, the air blown out from the exhaust side of the cooling fan 20 can dissipate heat and cool the server 60 inside the rack body 10, achieving air-cooled cooling of the server 60. When the ambient temperature of the server rack is high, the cooling component 30 can work in conjunction with the cooling fan 20 to dissipate heat and cool the server 60. The cooling component 30 can use low-temperature coolant and employ heat exchange to cool the intake side of the cooling fan 20, thereby improving the heat dissipation and cooling effect on the server 60. In this embodiment of the invention, both the cooling fan 20 and the cooling component 30 are located inside the rack body 10, and can directly act on the server 60 inside the rack body 10, thus ensuring the heat dissipation and cooling effect on the server 60. This solves the technical problem in the prior art where simply changing the ambient temperature of the computer room to reduce the high temperature generated by the server during operation limits the heat dissipation effect on the server inside the rack. Furthermore, this embodiment of the invention can utilize a low-temperature environment to naturally cool the high-temperature coolant to a low-temperature coolant, thereby reducing energy consumption.

[0068] Reference Figure 4The heat dissipation system provided in this embodiment of the invention also includes a cooling tank 70 and a storage tank 80 connected to the cooling tank 70. The cooling tank 70 is connected to a drain pipe 314 in the server rack. The high-temperature coolant discharged from the drain pipe 314 is stored in the cooling tank 70 and cooled to a low-temperature coolant under natural cooling in a low-temperature environment. The storage tank 80 is used to store the low-temperature coolant and is connected to an inlet pipe 324 in the server rack. The storage tank 80 is used to provide low-temperature coolant to the inlet pipe 324.

[0069] Specifically, when the cooling system includes multiple server racks, these racks can share a single cooling tank 70 and storage tank 80. The storage tank 80 stores a sufficient amount of cryogenic coolant to meet the daytime usage needs of the cooling component 30. During the day, the high-temperature coolant discharged from the cooling component 30 is stored in the cooling tank 70. At night, when temperatures are lower, the high-temperature coolant stored in the cooling tank 70 is cooled to cryogenic coolant and flows into the storage tank 80 for storage. The storage tank 80 is designed with an insulated structure and uses insulating materials; for example, it can be designed with a double-layer vacuum structure and made of materials such as stainless steel or glass. The storage tank 80 can be placed outdoors to take full advantage of the low nighttime temperatures. The storage tank 80 is specifically connected to the inlet pipe 324 via a second connecting pipe 92, and the outlet pipe 314 is specifically connected to the cooling tank 70 via a third connecting pipe 93.

[0070] It should be noted that the cooling tank 70 itself may be equipped with a cooling component, which is used to cool the high-temperature coolant in the cooling tank 70, so that even when the temperature is consistently high at night, the high-temperature coolant can be cooled to a low-temperature coolant, so that the low-temperature coolant can be recycled to the cooling component 30.

[0071] Reference Figure 4 The cooling tank 70 and the storage tank 80 are connected by a first connecting pipe 91, and a solenoid valve 911 is provided on the first connecting pipe 91. The heat dissipation system also includes a second control module, which is electrically connected to the solenoid valve 911. The second control module is used to control the solenoid valve 911 to open when the high-temperature coolant in the cooling tank 70 is cooled to a low-temperature coolant, so that the low-temperature coolant in the cooling tank 70 flows into the storage tank 80.

[0072] Specifically, a second temperature sensor 71 is installed inside the cooling tank 70. The second temperature sensor 71 is electrically connected to the second control module. The second control module obtains the temperature of the coolant in the cooling tank 70 through the second temperature sensor 71 to determine whether the high-temperature coolant in the cooling tank 70 has been cooled to a low-temperature coolant. Specifically, the second control module can receive the temperature value transmitted by the second temperature sensor 71, and then determine whether the temperature value transmitted by the second temperature sensor 71 is less than or equal to a second preset value. If the temperature value transmitted by the second temperature sensor 71 is less than or equal to the second preset value, it is determined that the high-temperature coolant in the cooling tank 70 has been cooled to a low-temperature coolant, and the solenoid valve 911 is opened to allow the low-temperature coolant in the cooling tank 70 to flow into the storage tank 80.
