Abstract

The invention provides a machine room cooling device which comprises a fan, a temperature sensor arranged on a cabinet, and a controller connected with the temperature sensor and used for controlling the rotational speed of the fan, wherein the temperature sensor comprises a first temperature sensor and a second temperature sensor arranged at the air inlet and the air outlet of the cabinet; the controller is used for decreasing the rotational speed of the fan when the detected temperature difference value of the second temperature sensor and the first temperature sensor is smaller than the minimum value of a set interval; or the controller is used for increasing the rotational speed of the fan when the detected temperature difference value of the second temperature sensor and the first temperature sensor is larger than the maximum value of the set interval. The machine room cooling device achieves more precious adjustment of the cooling air supply amount, and achieves more efficient utilization of the cold airflow. The invention further provides a cooling air supply adjusting method.

Description

Technical field [0001] The present invention relates to the technical field of equipment cooling, and more specifically, provides a device for cooling a machine room. The present invention also provides a method for applying the above-mentioned device for cooling a machine room for cooling and air supply adjustment. Background technique [0002] There are a large number of IT equipment in the communication room. In order to ensure the normal operation of the IT equipment in the communication room, the IT equipment in the communication room needs to be cooled. [0003] The prior art provides a reinforced air supply floor device with a structure such as figure 1 As shown, the reinforced air supply floor device adopts the EC fan 14 arranged in the housing 15 for forced air supply, and the cold air flows out of the floor 13 after being guided by the adjustable air valve plate 11. Among them: the control of the EC fan 14 The device 12 can adjust the speed of the EC fan 14 according to t...
