Description

Technical Field

[0001] The embodiments of the present application relate to the field of server technology, and in particular to a server cabinet and a data center. Background Art

[0002] Prefabricated data center is a form of data center construction. Specifically, the various components of the data center are prefabricated in the factory and then simply assembled on site, thereby improving installation efficiency, speeding up the installation process, and controlling installation quality.

[0003] The main component of an assembled data center is the server cabinet. Since the server cabinet generates a large amount of heat during operation, in order to avoid the problem of excessive temperature causing a decrease in server operating efficiency, it is necessary to install an air handling unit (AHU) in conjunction with the server cabinet in the assembled data center and set a return air device on the server cabinet side to discharge the heat.

[0004] However, the return air devices of current prefabricated data centers are generally installed on the ceiling. In this method, the return air device and the server cabinet are installed separately, resulting in cross-construction at the delivery site, large amounts of engineering customization, and complex on-site installation.

The embodiment of the present application also provides a corresponding data center.

[0006] In a first aspect, the present application provides a server cabinet, which includes a cabinet device and a return air bin, wherein the cabinet device is coupled to the return air bin, and the cabinet device includes a hot channel, which is connected to the return air bin.

[0009] In this application, the server cabinet is placed in the server room. When the air-conditioning unit blows cold air into the server room, the cold air will enter the cabinet equipment for heat exchange.

By coupling the server cabinet device with the return air bin and decoupling it from the building body such as the ceiling, the delivery time of the data center is accelerated and the difficulty of construction work is reduced.

[0011] In a possible implementation manner of the first aspect, the cabinet device includes a device layer and a wiring layer, the wiring layer is located between the device layer and the return air silo, and the heat channel runs through the device layer and the wiring layer from top to bottom.

[0016] In this possible implementation, speeding up the flow of hot air is equivalent to speeding up the cooling efficiency of the server cabinet.

[0017] In a possible implementation manner of the first aspect, the top of the return air bin includes a gas spray hole.

[0018] In this possible implementation, the setting of the gas nozzle allows the gas fire nozzle of the computer room of the data center to penetrate deep into the return air compartment, thereby completing the function of extinguishing fire in the hot channel and improving the safety of the server cabinet.

[0019] In a possible implementation manner of the first aspect, the length and width of the return air silo are the same as those of the cabinet device.

[0020] In this possible implementation, the size of the return air silo is the same as that of the cabinet equipment, which facilitates construction and installation.

[0041] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0042] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0043] The following is an example of the application scenario involved in the embodiments of the present application.

[0044] Prefabricated data center is a form of data center construction. Prefabricated data center is to prefabricate the various components of the data center in the factory, and then simply assemble them on site, so as to improve the installation efficiency, speed up the installation process and control the installation quality.

[0045] The components of the prefabricated data center include power modules, building modules, etc., and its main component is the server cabinet. Since the server cabinet will generate a large amount of heat during operation, in order to avoid the problem of excessive temperature causing a decrease in server operating efficiency, it is necessary to install an air handling unit (AHU) in conjunction with the server cabinet in the prefabricated data center and set a return air device on the server cabinet side to discharge the heat.

[0046] However, the return air devices of current prefabricated data centers are generally installed on the ceiling. Figure 1 As shown, in this method, the return air device is installed separately from the server cabinet, resulting in cross-construction at the delivery site, large engineering customization, and complex on-site installation. Based on this, the embodiment of the present application provides a server cabinet for decoupling the return air silo of the server cabinet from the building body such as the ceiling, speeding up the delivery time of the data center and reducing the difficulty of construction operations. The embodiment of the present application also provides a corresponding server room. The following are detailed descriptions.

[0047] The server cabinet provided in the embodiment of the present application is described below in combination with the above application scenarios.

[0048] like Figure 2 As shown, an embodiment of the present application provides a server cabinet, and an embodiment of the server cabinet includes cabinet equipment and a return air plenum 300 .

[0049] Among them, refer to Figure 3 The cabinet device is coupled with the return air bin 300, and the cabinet device includes a hot channel 400, which is connected to the return air bin 300. The cabinet device is used to exchange heat with cold air input from the outside to obtain hot air, and the hot channel 400 is used to transport the hot air to the return air bin 300, and the return air bin 300 is used to output the hot air to the outside.

[0050] Specifically, the cabinet device is fixedly connected to the return air bin 300 to form a whole. The cabinet device includes one or more servers, and the servers are carried by the cabinet. Cold air can be understood as cold air or gas with a temperature less than a certain threshold, and hot air can be understood as hot air or gas with a temperature greater than a certain threshold. The cabinet device includes an equipment layer 100, a wiring layer 200 and a return air bin 300 from bottom to top, which are described below.

[0051] The equipment layer 100 is used to accommodate equipment, such as servers. Optionally, the cabinet equipment is a single cabinet, a double cabinet or a triple cabinet, and auxiliary measures such as side panels, blind panels and trays can be flexibly configured according to the needs of specific projects. The embodiment of the present application takes the cabinet equipment as a double cabinet as an example, that is, the cabinet equipment is composed of two rows of cabinets, the two rows of cabinets are placed back to back, and a space is left in the middle, and a cabinet door 101 is set at the position of the remaining space in the middle. The cabinet door 101 is used to close the remaining space to form a space inside the cabinet through which air can circulate, that is, a hot channel 400. The equipment layer 100 has a load-bearing capacity of more than 1,500 kilograms and can be used as a structural support to form an independent system of the building with the wiring layer 200 and the return air silo 300. It is prefabricated in the factory to achieve engineering productization.

[0052] like Figure 4 As shown, the wiring layer 200 is located between the equipment layer 100 and the return air bin 300, and the hot channel 400 runs through the equipment layer 100 and the wiring layer 200 from top to bottom. In the hot channel 400 located at the same height as the wiring layer 200, the hot channel 400 is surrounded by an aluminum alloy structure 201 and a solar panel 202, which can guide the hot air upward and enter the return air bin 300. The wiring layer 200 is fixed to the equipment layer 100, that is, the top of the cabinet, using an aluminum alloy structure 201, and is connected to the aluminum alloy structure 201 on the upper part of the hot channel 400. According to the standard, one support for the wiring layer 200 is set for every 2 cabinets (1.2m), and 3 to 5 layers of bridge supports can be set, and small busbars 203 can also be supported. According to standard requirements, the spacing between each layer of support is greater than 300mm.

[0053] The heat channel 400 may also be surrounded by sheet metal parts and the solar panels 202 , that is, the aluminum alloy structure 201 is replaced by sheet metal parts.

[0054] Furthermore, the middle wiring layer 200 is composed of a maintenance window frame and a wiring support. The maintenance window frame is composed of a metal frame and a detachable maintenance window. The metal frame is formed by bending and welding the sheet metal. The maintenance window is made of aluminum alloy profiles or sheet metal integrally bent and fixed to the maintenance window frame by a tool-free lock. The maintenance window frame is installed on the top of the cabinet rear door and fixed to the cabinet frame with M10 screws. The wiring support is made of aluminum alloy profiles. Relying on the cabinet top structure frame and load-bearing, the wiring support is connected to the hot channel 400 maintenance window frame, and the busbar and bridge support are integrated on the top of the cabinet. According to the specifications, the structural parts are designed to have one support for every 2 cabinets, so as to meet the load-bearing requirements of the busbar bridge. Each support is connected to the adjacent support with a structural part to ensure the stability of the support. The strong / weak current layered and partitioned design and deployment avoids the standardized connection design of strong / weak current crossover, and is quickly assembled and delivered on site. The wiring layer 200 is unobstructed and the support is detachable, which is convenient for the maintenance of the busbar, optical fiber or network cable. The small busbar can be removed and replaced as a whole.

[0055] like Figure 5 As shown, the return air bin 300 is a rectangular cavity hollowed out in the middle of the bottom plate 302, and the size of the bottom plate hollowing is consistent with the hot channel 400, so that hot air can enter the return air bin 300 from the hot channel 400. The length of the return air bin 300 is consistent with the length and width of the entire cabinet equipment. The return air bin 300 is also provided with a docking port 301 for outputting the hot air in the return air bin 300.

[0056] Furthermore, the return air bin 300 is composed of a return air bin side frame 303, a return air bin interconnecting beam 304, an inclined support 305, a rock wool board 306 and an L-shaped fixing part 204 (sheet metal). The return air bin side frame 303 is installed above the support for the wiring in the direction of the front door of the cabinet, and is formed by sheet metal bending and welding. The rock wool board 306 is installed on the inner side close to the outside, and the rock wool board 306 is fixed to the inside of the return air bin side frame 303 by an L-shaped sheet metal 204. The return air bin interconnecting beam 304 is installed on the maintenance window frame. The return air bin interconnecting beam 304 is divided into two layers, the lower layer is fixed to the wiring layer support, and the upper layer is installed flush with the top of the return air bin side frame 303, and the two ends are fixed to the return air bin side frame 303. The installation spacing of the return air bin interconnecting beam 304 is the same as that of the cabinet equipment, and a group of 2-3 cabinets is used. The inclined support 305 is used to strengthen the strength of the return air bin interconnection beam 304 and the return air bin side frame 303. The inclined support 305 is made of sheet metal and is fixed to the return air bin interconnection beam 304 and the return air bin side frame 303 by screws. The L-shaped fixing part 204 is used to fix the rock wool board 306. The rock wool board 306 is installed in two layers, the lower layer is installed on the top of the wiring support, and the upper layer is installed at the position of the upper return air bin interconnection beam 304. The whole body forms an independent closed cavity with the return air bin 300, the wiring layer 200 and the equipment layer 100. The air outlet can be made on the air conditioning side to connect the return air with the wall air conditioning return air outlet. The rock wool opening on the top of the return air bin 300, that is, the gas spray hole is set, so that the gas fire nozzle of the computer room of the data center can penetrate into the return air bin 300 to complete the function of extinguishing the fire in the hot channel 400.

[0057] The rock wool board 306 can also be replaced by a solar panel 202, and the L-shaped fixing piece 204 can be replaced by an aluminum alloy profile.

[0058] Correspondingly, each structure in the equipment layer 100, the wiring layer 200 and the return air plenum 300 in the server cabinet provided in the embodiment of the present application can also be adaptively replaced to meet the different needs of users.

[0059] Optionally, the cabinet device further includes a first blowing device, and the return air chamber 300 includes a second blowing device. The first blowing device is used to accelerate the flow speed of hot air in the hot channel 400, and the second blowing device is used to accelerate the flow speed of hot air in the return air chamber 300, thereby accelerating the heat exchange cycle of the entire server cabinet and improving the heat dissipation efficiency.

[0060] like Figure 6 and Figure 7 As shown (circles indicate directions toward the outside of the paper, and crosses indicate directions toward the inside of the paper), the external cold air flows along direction A into the server room, and then flows along direction B into the cabinet equipment, where heat exchange occurs to obtain hot air. The hot air is transported to the return air bin 300 along direction C through the hot channel 400, and the return air bin 300 outputs the hot air to the outside along direction D, completing a heat cycle.

[0061] In the embodiment of the present application, the server cabinet includes a cabinet device and a return air bin, the cabinet device is coupled with the return air bin, the cabinet device includes a hot channel, and the hot channel is connected to the return air bin. The cabinet device is used to exchange heat with cold air input from the outside to obtain hot air, the hot channel is used to transport the hot air to the return air bin, and the return air bin is used to output the hot air to the outside. By coupling the server cabinet device with the return air bin and decoupling it from the building body such as the ceiling, the delivery time of the data center is accelerated and the difficulty of construction work is reduced.

[0062] The server cabinet provided in the embodiment of the present application is introduced above. The data center provided in the embodiment of the present application is introduced below with reference to the accompanying drawings.

[0063] like Figure 8 As shown, an embodiment of the present application provides a data center, and an embodiment of the data center includes an air handling unit 500 and a server cabinet 600.

[0064] Specifically, the server cabinet 600 is the above Figure 2-Figure 7 In the server cabinet shown in FIG. , the air handling unit 500 may be an air conditioning unit, and the air handling unit 500 is used to output cold air to the cabinet equipment and receive hot air output from the return air silo 300 through the docking port 301. The air handling unit 500 and the server cabinet 600 are respectively located in two independent and separated spaces, for example, the air handling unit 500 is located in the air conditioning room, and the server cabinet 600 is located in the server room, and the air conditioning room and the server room are separated by a wall.

[0065] Optionally, a cold air plenum box 501 and a hot air plenum box 502 are provided between the air-conditioning room and the server room. The air handling unit 500 outputs cold air through the cold air plenum box 501, and the return air compartment 300 outputs hot air through the hot air plenum box 502, thereby avoiding contact between cold air and hot air.

[0066] Among them, Fig. 9 and Fig.10As shown, the lower part of the wall is a louver, and the air handling unit sends cold air into the server room along the direction A through the louver to cool the servers in the server room. The cold air enters the server from the front along the direction B, and the hot air after heat exchange with the server is concentrated in the hot channel at the rear of the server. Driven by the wind pressure, the hot air flows upward along the direction C in the hot channel, returns to the air-conditioning room through the return air bin along the direction D, and enters the air handling unit for the next heat exchange cycle.
