technical field

The invention relates to the field of water circulation heat dissipation, in particular to a water cooling system for a data center.

Background technique

Building a comprehensive data center can facilitate data maintenance and application, improve the data processing capability of traditional power data networks, and is of great significance to building an "Internet +" smart grid. The biggest difference between a data center and other power grid sites is that there are There are many computer rooms, and the construction of the computer room has high requirements for heat dissipation. The existing technology has some problems in heat dissipation, such as high energy consumption, insufficient heat dissipation capacity, and high noise.

For example, the invention of Authorized Announcement No. CN102869237B discloses a cooling system for a server and a communication cabinet, including a server and a communication cabinet. The cabinet is provided with a water cooling circulation pipe for absorbing the heat emitted by the server and the heat in the cabinet. A water pump connected to the water cooling circulation pipeline and a heat transfer device are arranged outside the cabinet, and the heat transfer device includes a heat exchanger and a heat pipe. The water cooling circulation pipe is arranged on the back side or the left and right sides of the server or communication equipment. The water cooling circulation pipe exchanges heat with the public tap water pipe through the heat conduction device, and the tap water in the tap water pipe will take away the absorbed heat, thereby Improve the cooling efficiency of the cabinet.

The above technology helps the cooling system of the cabinet to dissipate heat through tap water. There are some drawbacks. First of all, the cooling system is combined with the water for personnel, which may easily cause the water temperature to be unstable when using water, which affects the use. The flow of tap water depends on the water consumption, such as night and other time periods for a long time. The slower water flow rate cannot help heat dissipation. In order to continue to dissipate heat, additional power units are required, so the heat dissipation capacity is still poor, and energy consumption cannot be effectively reduced.

The power required by the circulation device 2 will ultimately reduce energy consumption. At the same time, since the water tank 5 is on the roof 4, the rainwater flowing in the auxiliary cooling pipe 7 does not require additional power, and the entire process can be completed only by the rainwater’s own gravity. Monitor the temperature of the water cooling circulation device 2 to determine the opening and closing of the control valve without wasting rainwater.

The water tank 5 includes a drain port, the side wall section where the drain port is located is lower than the adjacent side walls, and the drain port is connected to the drain pipe 8 . Due to the limited capacity of the water tank 5, if there is too much rainfall and the control valve is fully opened, the water still cannot be effectively drained, and the drainage port needs to be intervened to prevent the rainwater from overflowing and causing adverse effects on the roof 4.
