A roof-mounted heat-dissipating whole cabinet server architecture

technical field

The invention relates to the technical field of data center and server design, in particular to a roof-type heat-dissipating whole cabinet server architecture.

Background technique

With the rapid development of information technology, traditional business has shown a diversified development model, and centralized data management has become an important cornerstone for improving the core competitiveness of the industry. On the one hand, it can carry out immediate risk control on the business, and on the other hand, it can also support the large-scale and low-cost expansion of new businesses. Electronicization is to build a comprehensive network operation mode through the use of network and information processing technology in traditional business. Under the trend of large data concentration, the data center began to be extended from the center to cover the branch business, and the existing network infrastructure was constructed and transformed. The goal of the transformation was to build a backbone network integrating voice, video and data applications. Realize that the data gradually moves from the region to the centralization.

For the traditional computer room, the heat dissipation requirements of a single cabinet with a heat generation of 2~3KW can only be met by adopting methods such as under-floor air supply and reasonable layout of hot and cold aisles. However, with high-performance computing and other demanding applications, the power consumption of a single cabinet has doubled to 10~30KW, and traditional cabinets have encountered greater difficulties. At the same time, when the lines are piled up under the floor, the airflow organization becomes more disordered, and the ideal cooling effect cannot be achieved, and the power of the air conditioner fan is also high, even exceeding the total IT power consumption.

The layout of the hot and cold aisles in the computer room prevents the air intake end of the cabinet from directly facing the exhaust end, so that the air intake end of the cabinet sucks in the surrounding cold air. However, due to the back-to-back arrangement of the cabinets, a large amount of exhausted hot air directly exchanges heat with the cold air in the equipment room, resulting in increased air-conditioning load. In addition, what is more serious is that due to the size of the room and the power characteristics of the air conditioner, the local hot air in the computer room is seriously accumulated and cannot be effectively cooled. All of these make the cabinets in these positions unable to work, or can only be left idle.

Based on the above problems, the present invention proposes a roof-mounted heat-dissipating cabinet server architecture.

Contents of the invention

The heat exchange roof can also adopt a water-cooled refrigeration device, the water-cooled refrigeration device includes an air inlet channel, a return air channel and a heat exchange tube, the heat exchange tube is arranged along the top of the cabinet, and the heat exchange tube includes a liquid inlet and a liquid outlet The liquid inlet is on the top and the liquid outlet is on the bottom. The heat exchange medium in the heat exchange tube is cold water; the hot air is discharged through the return air channel and exchanges heat with the heat exchange tube during the return air process.

The beneficial effects of the present invention are: the server architecture of the roof-type heat-dissipating complete cabinet is based on the design concept of "small overall computer room", relies on the standard cabinet as the physical space, and condenses the hot and cold channels at the computer room level into the cabinet, which occupies a small area , with high cooling efficiency, it is a server cabinet specially designed for high-density data centers; and the cabinet adopts the method of front air supply and upper return air, saving the floor space of the computer room.

detailed description

In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. It should be noted that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The roof-mounted heat-dissipating whole cabinet server architecture is based on the concept of a small overall computer room, relying on a standard cabinet as the physical space, condensing the hot and cold channels at the computer room level into the cabinet, and adopting the method of front air supply and upper return air for heat exchange;

The top of the cabinet 1 is equipped with an axial flow fan 3 and a heat exchange roof 4, the cabinet 1 is arranged in the machine room, and the server is placed in the cabinet 1;

The front door 2 of the cabinet is the air intake section 5. Cold air enters the cabinet 1 from the front door 2 of the cabinet and flows evenly across the surface of the server. The axial flow fan 3 makes the hot air flow through the heat exchange roof 4 along the air duct, and finally exhaust it to the outside of the cabinet 1.

The heat exchange roof 4 adopts an air-cooled refrigeration device, the air-cooled refrigeration device includes a return air channel, and a heat exchange pipe 7, the heat exchange pipe 7 is arranged along the top of the cabinet 1, and the heat exchange pipe 7 includes a liquid inlet 8 and a The liquid outlet 9, the liquid inlet 8 is on the top, and the liquid outlet 9 is on the bottom. The heat exchange medium in the heat exchange tube 7 is cold air; The heat pipe 7 performs heat exchange.

The heat exchange roof 4 can also adopt a water-cooled refrigeration device, the water-cooled refrigeration device includes an air inlet channel, a return air channel and a heat exchange tube 7, the heat exchange tube 7 is arranged along the top of the cabinet 1, and the heat exchange tube 7 includes an inlet The liquid inlet 8 and the liquid outlet 9, the liquid inlet 8 is on the top, the liquid outlet 9 is on the bottom, the heat exchange medium in the heat exchange tube 7 is cold water; the hot air is discharged through the return air channel, and is Heat exchange with the heat exchange tube 7 in the process.

In the server architecture of the roof-type heat dissipation whole rack, the cold air entering the rack 1 enters the rack 1 from the front door 2 of the rack and flows evenly across the surface of the server, and the hot air passing through the server gathers to the air return section 6 at the rear of the rack 1 . Due to the principle of thermal expansion and contraction, hot air rises and cold air descends, and the hot air naturally gathers on the top of the cabinet 1; at the same time, under the action of the axial flow fan 3 installed on the top of the cabinet 1, the hot air flows through the heat exchange along the air duct Roof 4, and finally discharged to the outside of cabinet 1. The hot air is effectively cooled after being exchanged by the heat exchange roof, and the temperature is lowered to become cold air. The cold air entering the cabinet 1 will not be affected, thereby improving the cooling efficiency of the cabinet 1 .
