数据中心data center

技术领域technical field

本发明涉及一种数据中心。The invention relates to a data center.

背景技术Background technique

目前针对数据中心的每一服务器内通常都设有风扇，利用该风扇将空气自服务器的一端吸入而自另一端排出而对服务器进行散热。然而，在服务器内设置风扇必将占用服务器内有限的空间，从而影响功能元件，如运算器、存储器等的安装密度。At present, a fan is usually provided in each server in a data center, and the fan is used to draw air from one end of the server and exhaust it from the other end to dissipate heat from the server. However, installing a fan in the server will inevitably occupy a limited space in the server, thus affecting the installation density of functional components such as computing units and storage devices.

发明内容Contents of the invention

鉴于以上内容，有必要提供一种数据中心，其可提高服务器中功能元件的安装密度。In view of the above, it is necessary to provide a data center that can increase the installation density of functional elements in servers.

一种数据中心，包括一柜体及设置于柜体内的若干组服务器，各组服务器之间以及外侧两组服务器与柜体的侧壁之间设有供空气流通的通道，这些通道被间隔地设置成冷通道及热通道，每一服务器的相对的两侧分别设有与通道连通的散热孔，该柜体内部于每一冷通道的上方均设有至少一冷却单元，该柜体内设有抽风装置，可使热通道的空气经冷却单元流入对应的冷通道，吸收服务器的热量后排入热通道。A data center includes a cabinet and several groups of servers arranged in the cabinet. There are passages for air circulation between each group of servers and between the two groups of servers on the outside and the side walls of the cabinet. These passages are spaced apart. It is arranged as a cold aisle and a hot aisle, and the opposite sides of each server are respectively provided with cooling holes communicating with the aisle, and the inside of the cabinet is provided with at least one cooling unit above each cold aisle, and the cabinet is provided with The ventilation device can make the air in the hot aisle flow into the corresponding cold aisle through the cooling unit, absorb the heat of the server and discharge it into the hot aisle.

相较现有技术，该数据中心利用冷通道及热通道之间的压差使冷空气流入服务器，无需在服务器中设置风扇，可留出更多空间安装功能元件。Compared with the existing technology, the data center utilizes the pressure difference between the cold aisle and the hot aisle to make the cold air flow into the server, and there is no need to install a fan in the server, leaving more space for installing functional components.

具体实施方式detailed description

请参阅图1，本发明数据中心包括一柜体10，该柜体10包括上壁11、与上壁11平行的下壁12以及连接上壁11与下壁12的左、右两侧壁13。柜体10内装设有若干组服务器40。每一组服务器40竖直设置于柜体10内。每一服务器40的左右两侧壁开设有散热孔(图未示)。各组服务器40之间以及外侧两组服务器40与柜体10的侧壁13之间设有供空气流通的通道。这些通道间隔地设置成冷通道101及热通道102，使得与每一冷通道101相邻的通道均为热通道102，而每一热通道102相邻的通道均为冷通道101。柜体10内部邻近上壁11的位置设有隔板15，该隔板15对应每一热通道102设有风流入口151，而对应每一冷通道101设有风流出口152。柜体10内部于隔板15上方且对正每一风流出口152处，即每一冷通道101的上方均设有一对呈“八”字形排布的冷却单元30。冷却单元30可以是散热器模组或者冷却器等。柜体10内部于隔板15上方对应每一冷却单元30设有一抽风装置20，该抽风装置20可以是轴流风扇或鼓风机。Referring to Fig. 1, the data center of the present invention includes a cabinet body 10, which includes an upper wall 11, a lower wall 12 parallel to the upper wall 11, and left and right side walls 13 connecting the upper wall 11 and the lower wall 12 . Several groups of servers 40 are installed in the cabinet body 10 . Each group of servers 40 is vertically arranged in the cabinet 10 . Cooling holes (not shown) are defined on the left and right side walls of each server 40 . Channels for air circulation are provided between each group of servers 40 and between the two groups of servers 40 on the outside and the side wall 13 of the cabinet 10 . These passages are arranged at intervals as cold passages 101 and hot passages 102 , so that passages adjacent to each cold passage 101 are hot passages 102 , and passages adjacent to each hot passage 102 are cold passages 101 . A partition 15 is provided inside the cabinet 10 adjacent to the upper wall 11 , and the partition 15 is provided with an air inlet 151 corresponding to each hot aisle 102 and an air outlet 152 corresponding to each cold aisle 101 . A pair of cooling units 30 arranged in a "eight" shape are arranged inside the cabinet body 10 on the top of the partition plate 15 and aligned with each air outlet 152 , that is, above each cold aisle 101 . The cooling unit 30 may be a radiator module or a cooler. Inside the cabinet body 10, above the partition 15, a ventilation device 20 is provided corresponding to each cooling unit 30, and the ventilation device 20 may be an axial flow fan or a blower.

柜体10内的风流方向如箭头A、B、C、D所示。工作时，抽风装置20运转，空气沿A方向流向对应的冷却单元30被冷却，然后沿B方向向下流入对应的冷通道101，从而于该冷通道101形成正压，同时于与该冷通道101相邻的热通道102形成负压区，使得空气自冷通道101沿C方向流入服务器40对服务器40进行冷却并将吸收热量的空气排入热通道102，而热空气由于自然对流及抽风装置20的作用沿D方向向上流动，从而将服务器40产生热量散发出去。由于隔板15将冷、热空气分隔开而在每一组服务器40的两侧分别形成冷通道101及热通道102，同时，抽风装置20使冷通道101内形成正压而热通道102内形成负压，从而利用冷通道101及热通道102之间压差使冷空气流入服务器40对其散热，而无须如在服务器40内设置风扇，以便安装更多的运算器、存储器等功能元件。The direction of wind flow in the cabinet body 10 is shown by arrows A, B, C, and D. When working, the ventilation device 20 operates, and the air flows along the direction A to the corresponding cooling unit 30 to be cooled, and then flows downwards along the direction B into the corresponding cold aisle 101, thereby forming a positive pressure in the cold aisle 101, and simultaneously with the cold aisle 101 The adjacent hot aisle 102 forms a negative pressure zone, so that air flows into the server 40 from the cold aisle 101 along the direction C to cool the server 40 and discharge the air that absorbs heat into the hot aisle 102, while the hot air is due to natural convection and drafting device The function of 20 flows upward along the direction D, so as to dissipate the heat generated by the server 40 . Because the partition 15 separates the cold and hot air, a cold aisle 101 and a hot aisle 102 are respectively formed on both sides of each group of servers 40. Negative pressure is formed, so that the cold air flows into the server 40 to dissipate heat by using the pressure difference between the cold aisle 101 and the hot aisle 102, without the need to install fans in the server 40 to install more functional components such as processors and memories.

另外，柜体10内于冷却单元30的位置附近装设有若干感温单元50，用于感测柜体10内进入冷却单元30的空气温度，利于控制抽风装置20转速，以调节各组服务器40两侧冷通道101及热通道102之间得压差，进而控制流入服务器40的冷空气的流速，实现以最低的抽风装置20功耗达到预期的散热效果。In addition, a number of temperature sensing units 50 are installed near the position of the cooling unit 30 in the cabinet 10 to sense the temperature of the air entering the cooling unit 30 in the cabinet 10, which is beneficial to control the speed of the exhaust device 20 to adjust the temperature of each group of servers. The pressure difference between the cold aisle 101 and the hot aisle 102 on both sides of 40 is obtained, and then the flow rate of the cold air flowing into the server 40 is controlled, so as to achieve the expected heat dissipation effect with the lowest power consumption of the ventilation device 20 .
