Description

a data center

technical field

The utility model generally relates to a data center, and more specifically relates to a data center heat dissipation scheme.

Background technique

A data center is a large-scale centralized computing facility, which usually includes a large number of servers. These servers are placed in racks to form a server system. Since there are many server systems and they are all installed in the data center, the overall cooling solution of the data center becomes very important.

At present, the heat dissipation methods of the server cabinet are mainly top heat dissipation and back heat dissipation. When the server cabinet uses the top heat dissipation, in order to improve the heat dissipation effect, it is necessary to reduce the sealing of the heat dissipation part to ensure the smooth flow of heat dissipation. If the airtightness is not enough, the heat dissipation of the cabinet will be reduced. Therefore, the cabinet with top heat dissipation is not ideal in terms of protection and heat dissipation.

When the server cabinet uses back cooling, the airflow must enter from the front of the cabinet door. However, in order to ensure a certain degree of safety, there are generally no cooling channels on the cabinet door, so the overall cooling performance of the cabinet with rear cooling is poor.

To sum up, at present, the heat dissipation method adopted by the existing server cabinets has a mediocre overall heat dissipation effect, and cannot take into account the dustproof effect well, so the heat dissipation method needs to be improved.

On the other hand, for the server cabinets currently cooled by air conditioners, since the air outlet of the air conditioner can only be located at one point, the temperature of the server closer to the air conditioner is lower, while the temperature of the server farther away from the air conditioner is higher, resulting in uneven cooling inside the cabinet. Due to the lack of cooling effect locally, there is still a risk of server failure due to overheating.

Contents of the invention

The purpose of the utility model is to provide a data center in order to overcome the deficiencies in the prior art.

In order to solve the problems of the technologies described above, the technical scheme adopted in the utility model is as follows:

Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings and examples.

As shown in Figure 1, the structural diagram of the data center of the present invention and the top view of the cooling system in the server rack of the data center of the present invention shown in Figure 2, a data center includes a plurality of server racks (1), located in the server rack The server (2) and the cooling system (3) located in the server rack; the cooling system (3) includes a heat exchanger (4) and a fan (5) arranged on the side of the heat exchanger, and the heat exchanger (4) of the cooling system ) is vertically placed in the server rack (1), the side of the heat exchanger (4) is parallel to the rear wall of the server rack (1); the fan (5) of the cooling system is parallel to the heat exchanger (4) placed side by side; the server racks (1) are placed side by side, the cooling system (3) and the server (2) are placed in different server racks at intervals, and the airflow direction and placement inside the server rack where the cooling system (3) is placed The direction of the wind flow inside the server rack of the server (2) is opposite; the cold air enters the inside of the server rack where the server (2) is placed for heat exchange with the server, and the cold air is heated and then sent to the nearby cooling system (3 ) of the server rack is cooled by the cooling system and then sent to the server rack next door with the server. The real data center rack has multiple such small cycles to complete the heat dissipation.

As shown in Figure 3, the structural diagram of the first embodiment of the data center of the present invention includes at least two columns of server racks in the data center, and each row of server racks is provided with servers and cooling systems at intervals, and the server racks of the cooling system are placed The air flow direction inside is opposite to the air flow direction inside the server rack where the server is placed. The air flow direction inside all the server racks where the server is placed is the same, and the air flow direction inside all the server racks where the cooling system is placed is also the same. The cold air enters the inside of the server rack where the server is placed to exchange heat with the server to be heated, and the hot air enters the server rack where the cooling system is placed and is cooled by the cooling system.

As shown in Figure 4, the structure diagram of the second embodiment of the data center of the present invention includes at least two rows of server racks in this embodiment. The cold air performs heat exchange. After being heated, the cold air is sent from the server rack with the server between the two rows of server racks. The cooling system draws hot air from the hot air area between the two rows of server racks for cooling. The hot air is then sent again to the other side of the server rack.

As shown in Figure 5, the structure diagram of the third implementation of the data center of the present invention includes two rows of server racks in the data center in this embodiment, and there is a cold air area between the two rows of server racks. The cold air area between the server racks sucks in cold air for heat exchange. After the cold air is heated, it is sent out from the other side of the server rack where the server is placed, and then the cooling system sucks in hot air for cooling. The cooled hot air is again It is fed into the cool air zone between the two rows of server racks.
