Description

A data center ventilation system with integrated solar chimney

technical field

The utility model belongs to the field of the influence of building structures on the thermal environment of data centers, in particular to a data center ventilation system integrating solar chimneys.

Background technique

The data center has the characteristics of high heat generation of equipment, uneven temperature distribution, and high energy consumption of air conditioning. At present, the air-conditioning system in the data center mostly adopts the floor air supply method. The system supplies air through the cold aisle. After cooling the equipment inside the cabinet, the heat is sent out through the return air vent on the ceiling. If the system parameter design is not reasonable, This will cause a large amount of heat to gather in the upper part of the computer room, causing the temperature in the upper part of the computer room to be significantly higher than other peripheral areas, forming a heat island effect. On the other hand, since there are many types of servers, the heat dissipation methods and heat dissipation are also different. This feature will easily cause the air supply and exhaust in some areas of the cabinet to be unsmooth, and the airflow organization will be chaotic, resulting in uneven temperature distribution inside a single cabinet and local temperature. If the temperature is too high, local hot spots will be generated, which will lead to low utilization rate of the air-conditioning cold source and reduce the operating efficiency of the air-conditioning. At the same time, the operation of the data center will also be plagued by problems such as air short circuit and recirculation.

In order to improve the airflow organization form, heat island effect, and local hotspots in the data center, most of them optimize the internal cabinets of the computer room and the form of supply and return air, but the way of optimizing by changing the structure of the computer room is very rare.

Therefore, a data center ventilation system with integrated solar chimney is designed.

Utility model content

Based on the above-mentioned background technology, the utility model designs a data center ventilation system integrating solar chimneys, which solves problems such as heat island effect and local hot spots inside the computer room while realizing safe and efficient year-round cooling of the computer room.

The utility model provides a data center ventilation system integrating a solar chimney, comprising: a high-precision air conditioner, a raised floor, servers with different rated power, multiple cabinets arranged in a machine room, a solar chimney (insulation wall, heat collecting plate, glass plate, damper, etc.). A vertical solar chimney is installed on the roof of the data center, and the cold air floats up to take away the heat, making the bottom-up system more complete and integrated. The Trombe wall supplies heat to the room in winter, which does not meet the year-round cooling needs of the computer room; the airflow velocity of the inclined solar chimney is related to its inclination angle, and the application in the data center using floor air supply will increase the resistance of air circulation and reduce the efficiency.

Wherein, the solar chimney is installed on the roof of the house above the heat channel, one side is an insulating wall, the heat collecting plate is close to the insulating wall, the middle is a chimney channel, the other side is a glass plate, and the top of the channel is a damper.

Wherein, the single cabinet is provided with an air inlet and an air outlet, and the raised floor in the cold aisle area is provided with openings.

Wherein, there are multiple rows of cabinets inside the computer room, each row has multiple cabinets, and multiple servers with different powers are arranged inside the cabinets.

Wherein, the heat collecting plate is a flat plate heat collector.

The beneficial effect of the data center ventilation system integrating the solar chimney is:

1. Effectively improve airflow organization form:

Before the solar chimney is integrated, cold air enters the front door of the cabinet through the raised floor, takes away the heat and discharges from the rear door of the cabinet, gathers at the top of the machine room and enters the return air vent of the air conditioner. Through this improvement, the solar chimney is set above the hot aisle, so that the heat taken away by the cold air through the cabinet can be directly discharged from the solar chimney without passing through other places in the computer room, and the airflow organization form is simpler and more effective.

2. Effectively reduce the temperature inside the computer room and even the cabinet:

The exhaust effect of the solar chimney makes the cold air in the cold aisle flow upwards, increases the amount of cold air inside the cabinet, reduces the mixing of hot and cold air, further reduces the temperature inside the computer room and inside the cabinet, and provides a guarantee for the safe and reliable operation of the server.

3. Energy saving and environmental protection

Before integrating the solar chimney, the air conditioner was completely used to process the air. After this improvement, the solar chimney uses more solar energy to discharge hot air, uses more primary energy, and reduces the use of secondary energy.

Referring to Figure 1, a data center ventilation system with integrated solar chimney includes: data center ventilation system 4, multiple server cabinets in the computer room 2, multiple high-precision air conditioners placed inside the computer room 3, raised floor 1, and solar chimney 600 , an insulating wall 601 , a heat collector 602 , a glass plate 604 , and a damper 603 .

Among them, the cabinets 2 are placed in the machine room in multiple rows, with multiple rows in each row, the raised floor 11 with openings is an air supply port, and the cabinet air exhaust port 12 .

Wherein, the solar chimney includes an insulating wall, a heat collecting plate, a glass plate, and an air valve. The solar chimney is installed on the roof of the house above the heat passage, one side is an insulating wall, the one close to the heat insulating wall is a heat collecting plate, the middle is a chimney passage, the other side is a glass plate, and the top of the passage is provided with a damper. The cold air sent by the high-precision air conditioner 3 enters the machine room through the open raised floor 11, enters through the front doors of multiple cabinets 2, takes away the heat emitted by the servers, and is exhausted from the air outlets 12 of the multiple cabinets 2. The exhaust function of the chimney 600 makes the exhausted hot air rise into the chimney, and the heat collecting plate 602 collects the solar radiation energy passing through the glass plate 600, and the heat of the heat collecting plate heats the air in the chimney, increasing the temperature difference between the inside and outside of the chimney to enhance the thermal pressure , At the same time, the suction effect of the chimney is used to enhance natural ventilation and enhance the ventilation effect.

The data center ventilation system integrated with the solar chimney discharges the heat in the computer room through the thermal pressure exhaust function of the solar chimney, the air flow is more uniform, and the mixing of cold and heat is reduced.

The utility model has simple design and remarkable practical effect, ensures safe and reliable operation of servers in the computer room, and effectively improves the thermal environment in the computer room.
