Abstract
Description
Technical Field
[0001] This utility model relates to the field of data center technology, and in particular to an integrated rack with a single-sided movable enclosed passage. Background Technology
[0002] Regarding hot and cold aisle isolation, in the open rack layouts widely used in current data centers, cold and hot aisles are only formed by the arrangement of racks, lacking a physical enclosure. When air is supplied from the bottom plate or top, cold air easily escapes from the unenclosed side of the rack, while hot air flows back into the cold aisle through the gaps between adjacent racks, creating an airflow short circuit. Hot air also flows back directly through empty areas, causing localized hot spots and reducing cooling efficiency.
[0003] To solve this problem, the main approach now is to install fixed metal or acrylic baffles (such as side panels or top panels) on one side of the cabinet to create a permanent cold or hot aisle enclosure. However, this method has the drawback of the enclosed space not being adjustable in size or being unable to be moved flexibly. Utility Model Content
[0004] The purpose of this invention is to provide an integrated rack with a single-sided movable closed channel, which can realize the closure of the single-sided channel to prevent cold loss or hot air backflow, thereby improving the cooling capacity and thermal performance of the entire rack.
[0005] An integrated rack with a single-sided movable enclosed passage includes a rack body with openings on the front and rear sides. A movable outer shell with a "U"-shaped cross-section is provided on the rear side of the rack body. The rack body is installed inside the movable outer shell through the opening of the movable outer shell, and a gap is left between the rear side of the rack body and the rear side wall of the movable outer shell, which forms an air passage.
[0006] The movable outer shell is movably connected to the outer walls of the left and right sides of the frame body, respectively. The movable outer shell can move back and forth relative to the frame body, thereby changing the size of the air passage.
[0007] The above structure seals the air passage, thereby preventing cold loss or hot air recirculation and improving the cooling capacity and thermal performance of the entire rack.
[0008] At the same time, the area of the air passage can be changed by moving the outer shell, thus adapting to changes in actual engineering.
[0009] Furthermore, guide rails are installed on the outer walls of both the left and right sides of the frame body, and guide grooves that cooperate with the corresponding guide rails are provided on the inner walls of the left and right sides of the movable housing, thereby realizing the forward and backward movement of the movable housing.
[0010] The combination of guide grooves and guide rails enhances the stability of the housing's movement.
[0011] Furthermore, scale markings are provided on the guide rail.
[0012] The specific distance the outer casing moves is known by the markings on the guide rail.
[0013] Furthermore, a blind plate is detachably installed on the front side of the frame body.
[0014] Furthermore, N partitions are installed along the vertical direction inside the rack body, and all partitions divide the interior of the rack body into N+1 server placement areas.
[0015] Furthermore, the blind plate covers one or more of the server placement areas.
[0016] Furthermore, a handle is installed on the outside of the blind plate.
[0017] Beneficial effects: This utility model seals the air passage, thereby preventing the loss of cold air or the recirculation of hot air, and improving the cooling capacity and thermal performance of the entire frame.
[0018] At the same time, the area of the air passage can be changed by moving the outer shell, thus adapting to changes in actual engineering. Attached Figure Description

[0025] Figure 7 This is embodiment six of the application of this utility model. Detailed Implementation
[0026] The specific embodiments and working principle of this utility model will be further described in detail below with reference to the accompanying drawings.
[0027] like Figure 1As shown, the integrated rack with a single-sided movable enclosed channel includes a rack body 1 with open front and rear sides and a movable outer shell 2 with a "U"-shaped cross-section. The rack body 1 can be made of stainless steel, and the movable outer shell 2 can be made of stainless steel or high carbon steel, which have poor thermal conductivity and are economical.
[0028] like Figure 1 As shown, the frame body 1 is embedded and installed inside the movable housing 2 through the opening of the movable housing 2, and there is a gap between the rear side of the frame body 1 and the rear side wall of the movable housing 2. This gap forms an air passage a, which can be used as a cold air passage or a hot air passage depending on the actual use.
[0029] like Figure 1 As shown, guide rails 3 are installed on the outer walls of both sides of the frame body 1. The guide rails 3 are marked with a scale of 0-60cm. The inner walls of the movable outer shell 2 are provided with guide grooves that cooperate with the corresponding guide rails 3.
[0030] The guide rail 3 and the guide groove are installed together to movably connect the frame body 1 and the movable outer shell 2, thereby realizing the adjustment of the size of the air passage a by moving the movable outer shell 2 back and forth.
[0031] like Figure 1 As shown, seven 60cm×60cm×1cm partitions 4 are installed inside the frame body 1 along the vertical direction. The two sides of the partitions 4 are fixedly connected to the inner walls of the left and right sides of the frame body 1, respectively.
[0032] The partition 4 is made of stainless steel to ensure the strength and durability of the structure.
[0033] like Figure 1 As shown, seven partitions 4 divide the interior of the rack body 1 into eight server placement areas of identical size, each capable of holding one server.
[0034] like Figure 1 As shown, a blind plate 5 is detachably installed on the front side of the frame body 1. The two sides of the blind plate 5 are respectively fitted with the inner walls of the left and right sides of the frame body 1 with a gap of 1mm.
[0035] The blind plate 5 is a lightweight, heat-insulating polyurethane insulation board.
[0036] like Figure 1 As shown, each blind plate 5 covers one of the server placement areas.
[0037] Example 1:
[0038] like Figure 2As shown, the current state is that all eight server placement areas have servers, and none of the eight server placement areas have blind plates 5 installed. The air passage a is a cold air passage.
[0039] like Figure 2 As shown, the lower end of the cold air duct is the air inlet 6, which is connected to the air supply device, and the opening in the server placement area away from the cold aisle is the air outlet 7.
[0040] At this time, the cold air delivered by the air supply device flows upward along the cold air channel and is successively distributed to the eight server placement areas to cool the servers. After passing through the servers, the cold air becomes hot air and flows out from the air outlet 7.
[0041] Example 2:
[0042] like Figure 3 As shown, the current state is that all eight server placement areas have servers, and none of the eight server placement areas have blind plates 5 installed. The air passage a is a cold air passage.
[0043] like Figure 3 As shown, the upper end of the cold air duct is the air inlet 6, which is connected to the air supply device, and the opening in the server placement area away from the cold aisle is the air outlet 7.
[0044] At this time, the cold air delivered by the air supply device flows downward along the cold air channel and is successively distributed to the eight server placement areas to cool the servers. After passing through the servers, the cold air becomes hot air and flows out from the air outlet 7.
[0045] Example 3:
[0046] like Figure 4 As shown, the current state is that all eight server placement areas have servers, and none of the eight server placement areas have blind plates 5 installed. The air passage a is a hot air passage.
[0047] like Figure 4 As shown, the opening in the server placement area away from the hot aisle is the air inlet 6, which is connected to the air supply device, and the upper end of the hot air duct is the air outlet 7.
[0048] At this time, the cold air delivered by the air supply device becomes hot air after passing through the server and is gathered into the hot air duct. The hot air flows upward along the hot air duct and flows out from the air outlet 7.
[0049] Example 4:
[0050] like Figure 5 As shown, the current state is that servers are placed in five server placement areas, and the three server placement areas without servers are equipped with blind plates 5. The air passage a is a cold air passage.
[0051] like Figure 5As shown, the lower end of the cold air duct is the air inlet 6, which is connected to the air supply device, and the opening in the server placement area away from the cold aisle is the air outlet 7.
[0052] At this time, the cold air delivered by the air supply device flows upward along the cold air channel and is successively distributed to the five server placement areas to cool the servers. After passing through the servers, the cold air becomes hot air and flows out from the air outlet 7.
[0053] Meanwhile, the blind plate 5 isolates hot air, so hot air will not flow back into the cold aisle along the three server placement areas where no servers are placed, thus preventing it from affecting the temperature of the cold air.
[0054] Example 5:
[0055] like Figure 6 As shown, the current state is that servers are placed in five server placement areas, and the three server placement areas without servers are equipped with blind plates 5. The air passage a is a cold air passage.
[0056] like Figure 6 As shown, the upper end of the cold air duct is the air inlet 6, which is connected to the air supply device, and the opening in the server placement area away from the cold aisle is the air outlet 7.
[0057] At this time, the cold air delivered by the air supply device flows downward along the cold air channel and is successively distributed to the five server placement areas to cool the servers. After passing through the servers, the cold air becomes hot air and flows out from the air outlet 7.
[0058] Meanwhile, the blind plate 5 isolates hot air, so hot air will not flow back into the cold aisle along the three server placement areas where no servers are placed, thus preventing it from affecting the temperature of the cold air.
[0059] Example 6:
[0060] like Figure 7 As shown, the current state is that servers are placed in five server placement areas, and the three server placement areas without servers are equipped with blind plates 5. The air passage a is a hot air passage.
[0061] like Figure 7 As shown, the opening in the server placement area away from the hot aisle is the air inlet 6, which is connected to the air supply device, and the upper end of the hot air duct is the air outlet 7.
[0062] At this time, the cold air delivered by the air supply device becomes hot air after passing through the server and is gathered into the hot air duct. The hot air flows upward along the hot air duct and flows out from the air outlet 7.
[0063] In particular, the above embodiments can all change the area of the air passage a by moving the outer shell 2, thereby adapting to changes in actual engineering, and the specific moving distance can be known through the scale of the guide rail 3.
