Data center and its cooling system

Abstract

The invention discloses a data center, comprising a cabinet and at least one server system, wherein the cabinet is provided with an elevated floor, and the at least one server system is arranged in the cabinet; the server system comprises multiple severs at different heights; and the elevated floor has a ventilating grate hole. The cooling system used for the data center comprises an air conditioner, multiple temperature sensors respectively arranged nearby the exhaust ends of the servers, a group of guide fans arranged nearby the ventilating grate hole of the elevated floor, and a control module electrically connected with the air conditioner, the temperature sensor and the guide fans, wherein the cool air from the air conditioner is injected below the elevated floor; the guide fans can drive the cool air to pass through the ventilating grate hole to flow upwards at an acceleration mode; and the control module adjusts the rotation speed of the guide fan based on the temperature value acquired by the temperature sensor, so as to enable the cool air to be uniformly distributed, and servers at different heights to uniformly cool. Compared with the prior art, the data center provided by the invention can improve the cooling efficiency, so as to save energy.

Description

Technical field [0001] The invention relates to a data center and its heat dissipation system. Background technique [0002] With the development of online applications, the demand for data centers has grown rapidly. A data center is a large-scale centralized computing facility, which usually includes a large number of servers, which are placed in racks. Since there are many server systems and are all installed in the data center, the overall heat dissipation scheme of the data center becomes very important. [0003] A common way to dissipate heat is to set up a raised floor, and the cold air generated by air conditioning equipment is injected under the raised floor. The raised floor is provided with ventilation grid holes in the front of each rack for cooling air to pass through the raised floor and flow into the server to dissipate heat. Due to the different placement of servers, servers close to the ventilation grilles, such as those placed on the lower level of the rack, will...

AI Technical Summary

Problems solved by technology

Due to the different locations of the servers, the servers that are close to the ventilation grilles, such as those placed on the lower rack, will inhale more cold air than the servers that are farther away from the ventilation grills, such as those placed on the upper rack, resulting in Uneven air intake between servers

Therefore, the total cooling capacity of the air conditioner must be large enough to meet the heat dissipation requirements of the servers that are far away from the ventilation grid holes, so that the intake of cold air by the servers that are close to the ventilation grid holes exceeds their heat dissipation requirements, resulting in energy waste
