Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and more specifically to a cooling device for a data center. Background Technology
[0002] Data centers, as the primary carriers of network infrastructure, provide support for technological innovation and application across various industries. Currently, most small and medium-sized data centers are built in buildings where space is extremely limited, and high density has always been a pursuit for IT equipment. Existing small and medium-sized data centers have bulky air handling units that occupy a lot of server rack space. Furthermore, the cold air used for cooling is directly discharged into the building and then enters the server racks from within the building. However, the ventilation holes in the server racks dissipate heat and exhaust it outwards during operation, meaning that the cold air mostly acts on the periphery of the server racks and has difficulty entering the racks themselves, resulting in low cooling efficiency. Summary of the Invention
[0003] To overcome the shortcomings of existing technologies, a cooling device for data centers is provided to solve the problems of large size of existing air handling equipment that occupies rack space and difficulty in getting cooling air into the rack, resulting in low cooling efficiency.
[0004] To achieve the above objectives, a data center cooling device is provided, comprising: The computer room has an inner cavity formed in its side wall. The side wall has an air inlet and an air outlet that communicate with the inner cavity. The computer room is equipped with server racks, and the air outlet is connected to the server racks through an air supply duct. Heat exchange tubes are laid inside the cavity; A container for holding coolant is installed outside the machine room. Both ends of the heat exchange tube are connected to the container via pipelines, and a delivery pump is installed on the pipelines. A cooler for cooling the coolant is installed inside the container.
[0005] Furthermore, the outer wall of the heat exchange tube is provided with a plurality of heat dissipation fins, which are spaced apart along the circumference of the heat exchange tube and along the length of the heat exchange tube.
[0006] Furthermore, a heat-conducting coil is wound around the outside of the plurality of heat dissipation fins.
[0007] Furthermore, a filter is detachably installed in the middle of the container.
[0008] Furthermore, the container is equipped with two opposing partitions, the filter is embedded between the two partitions, the partitions are provided with flow guide holes, the container is provided with an outlet, and the outlet is aligned with the filter.
[0009] Furthermore, the computer room includes a base plate, side plates, and a top plate. The side plates are erected on the base plate, and the top plate is connected to the top of the side plates. The cavity is formed within the side plates and the top plate.
[0010] The beneficial effects of this invention are that the cooling equipment of the data center of this invention introduces external air into the cavity through a fan, and cools the air in the cavity through the cooperation of the housing and heat exchange pipes. Then, the cooled air in the cavity is introduced into the rack. The cooled air enters directly from the bottom of the rack and is discharged from the heat dissipation holes at the top of the rack. This ensures that the cooling air delivery route does not conflict with the heat dissipation route of the rack itself, thereby ensuring the utilization rate of the cooling air, reducing the loss of cooling air in the computer room, improving the overall cooling module's performance, and avoiding encroachment on the rack space in the computer room.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] Reference Figures 1 to 5 As shown, the present invention provides a cooling device for a data center, including: a computer room 1, a heat exchange pipe 2, a container 3, and a cooler 4.
[0020] In this embodiment, the side wall of the computer room 1 forms an inner cavity. An air inlet and an air outlet communicating with the inner cavity are provided on the side wall. A server rack 11 is installed inside the computer room 1. The air outlet is connected to the server rack 11 via an air supply duct.
[0021] Specifically, the server room contains multiple server racks. These racks are used to house data center equipment. Server room 1 includes a base plate 12, side plates 13, and a top plate 14. The side plates 13 are erected on the base plate 12. The top plate 14 is connected to the top of the side plates 13. A cavity 10 is formed within the side plates 13 and the top plate 14.
[0022] Heat exchange tube 2 is installed inside cavity 10. (See reference...) Figure 5 As shown, the heat exchange tubes inside the cavity of computer room 1 are S-shaped. The heat exchange tubes are metal pipes with good thermal conductivity.
[0023] As a preferred implementation method, see [reference]. Figure 2 As shown, the outer wall of the heat exchange tube 2 has multiple heat dissipation fins 21. The multiple heat dissipation fins 21 are spaced apart along the circumference of the heat exchange tube 2. The heat dissipation fins 21 are arranged along the length of the heat exchange tube 2.
[0024] In this embodiment, four heat dissipation fins are provided on the outer side of the heat exchange tube. The four heat dissipation fins are arranged at equal intervals along the circumference of the heat exchange tube.
[0025] Continue reading Figure 1 and Figure 2 As shown, a plurality of heat dissipation fins 21 are wound with heat-conducting coils 22. In this embodiment, heat-conducting metal wires are wound around the outside of the heat dissipation fins on the heat exchange tube. The heat-conducting metal wires are arranged in a spiral shape.
[0026] Heat dissipation fins and heat conduction coils are installed on the outside of the heat exchange tubes to increase the heat dissipation area and improve cooling efficiency.
[0027] The container 3 is used to hold coolant (such as water). The container 3 is installed outside the machine room 1. Both ends of the heat exchange tube 2 are connected to the container 3 via pipelines. A transfer pump 31 is installed on the pipelines.
[0028] In this embodiment, combined with Figure 1 and Figure 2 As shown, the storage box is located at the rear of the computer room. The side panels of the computer room include at least four sides. The four side panels are arranged along the outer edge of the base plate. The four side panels are rectangular. The storage box is located on the outer side of the side panels at the rear of the computer room.
[0029] Cooler 4 is installed inside housing 3. Cooler 4 is used to cool the coolant.
[0030] In a preferred embodiment, a filter 33 is detachably installed in the middle of the housing 3. By installing the filter, impurities are prevented from accumulating inside the heat exchange tubes and forming scale, which would affect the heat exchange efficiency. In this embodiment, two opposing partitions 32 are installed inside the housing 3. A filter 33 is embedded between the two partitions 32. The partitions 32 have flow guide holes. The housing 3 has an outlet. The outlet is aligned with the filter 33.
[0031] Combination Figure 3 and Figure 4 As shown, one end of the container is connected to the outlet end of the heat exchange tube via an inlet pipe, and the other end of the container is connected to the inlet end of the heat exchange tube via an outlet pipe. The coolant in the container is fed into the heat exchange tube via the outlet pipe by a delivery pump, and then discharged back into the container via the inlet pipe to form a circulation.
[0032] The data center cooling equipment of this invention has several server racks mounted on the base plate of the room. The server racks are connected in series via piping. A cavity is formed within the side and top panels of the room. Heat exchange pipes are installed within the cavity. Both ends of the heat exchange pipes extend to the back of the room. The portion of the heat exchange pipes within the cavity is arranged in an S-shaped routing pattern. Air outlets are located at the bottom of the side panels of the room, allowing communication between the interior and exterior spaces and the exhaust of hot air from the room. The cavity is connected to the bottom of the server racks via piping. Right-angle pipes are installed on the lower inner side of the opposite side panels of the room. The top of the right-angle pipes extends to the bottom of the cavity. A detachable connecting pipe is installed between the bottom end of the right-angle pipe and one end of the bottom pipe. Ventilation ducts are installed at the bottom of both sides of the room, and these ducts are located within the air outlets.
[0033] A mounting platform is connected to the lower rear of the computer room. A container is mounted on the platform. Both ends of the heat exchange tubes are connected to the container via inlet and outlet pipes, respectively. A fan is also installed at the upper rear of the computer room. The fan is located at the air inlet, drawing outside air into the cavity. A filter element is installed at the bottom inlet of the fan to filter the outside air.
[0034] The heat exchange tube has cross-shaped heat dissipation fins installed on its outer wall. A heat-conducting coil is spirally wound around the periphery of the heat dissipation fins. Both the heat dissipation fins and the heat-conducting coil are made of copper.
[0035] Flanges are installed at both ends of the connecting pipe, the bottom end of the right-angle pipe, and the end of the base pipe. A telescopic section is provided in the middle of the connecting pipe. The end of the base pipe is designed as an upward-curved right angle. The connecting rod is installed vertically between the right-angle pipe and the base pipe. The telescopic section on the connecting pipe is a folded pipe for easy installation. Sealing rings are provided on the flanges at both ends of the connecting rod. The flanges are connected using bolts.
[0036] A first transfer pump is installed at the connection between the inlet pipe and the container. A drain pipe is installed at the outlet end of the first transfer pump. The bottom end of the drain pipe extends to the top of the container's inner cavity. A second transfer pump is installed at the connection between the outlet pipe and the container. A discharge pipe is installed at the outlet end of the second transfer pump. The bottom end of the discharge pipe extends to the bottom of the container's inner cavity. A water exchange pipe connected to an external drainage pipe is connected to the bottom of the container, and a water replenishment pipe connected to an external water supply pipe is connected to the top of the container.
[0037] The container has two symmetrically spaced partitions in the center of its inner cavity. Each partition has a flow guide hole in its center. An insertion slot is located at the top of the container between the two partitions. A filter box is installed between the two partitions via the insertion slot. A mounting plate is connected to the top of the filter box. Grooves are provided on both sides of the filter box. A filter (purified water plate) is installed in the center of the filter box's inner cavity. The purified water plate uses a filter material suitable for filtering and purifying coolant, as is currently available in the technology. A collection tank is located at the bottom of the filter box, below the first groove opening. Impurities filtered by the purified water plate flow downwards into the collection tank for sedimentation and collection. A cooler is installed in the inner cavity of the container near the discharge pipe. The cooler is selected from existing cooling devices used for cooling coolant. The filter box is inserted into the container and secured by the mounting plate for easy disassembly and replacement.
[0038] During operation, an external air is drawn into the cavity by a fan. The first and second delivery pumps are activated, causing the coolant in the container to circulate. The coolant, after being cooled by the cooler, is then delivered to the heat exchange tubes. The air in the cavity is cooled by heat exchange around the heat exchange tubes. The cooled air then enters the bottom tube through a right-angle pipe and connecting pipe, and from there enters the bottom of the cabinet's interior. When the cabinet (which is not a sealed enclosure; some cabinets have ventilation holes) dissipates heat, the cooling air enters the cabinet and cools it. Afterward, the cooling air and the exhaust air from the cabinet are discharged through the ventilation holes on the cabinet. After a period of use, the old water in the container is drained through the water change pipe, and new water is added to the container through the water replenishment pipe. The water in the container is filtered by a water purification plate as it circulates through the heat exchange tubes.
[0039] The data center cooling equipment of this invention introduces external air into a cavity through a fan, and cools the air in the cavity through a housing and heat exchange pipes. The cooled air in the cavity is then introduced into the server rack. The cooled air enters directly from the bottom of the server rack and exits from the heat dissipation holes at the top of the server rack. This ensures that the cooling air delivery route does not conflict with the heat dissipation route of the server rack itself, thereby ensuring the utilization rate of the cooling air, reducing the loss of cooling air in the computer room, improving the overall cooling module's performance, and avoiding encroachment on the server rack space in the computer room.
