Evaporative cooling unit and data center

Abstract

The invention provides an evaporative cooling unit and a data center. The evaporative cooling unit comprises an outdoor channel, an indoor channel and a heat exchange device; the evaporative cooling unit further comprises a filter screen and a defrosting device which are arranged in the outdoor channel; the defrosting device is located on the side, close to an air inlet of the outdoor channel, of the filter screen; the defrosting device comprises a heat exchange film; a first channel and a second channel which are arranged in a crossed mode are arranged in a heat exchange film; wherein the first channel is in communication with an air inlet of the outdoor channel; the second channel is in communication with the indoor channel; the first channel is in communication with the second channel; the defrosting device further comprises a switch valve; and the switch valve is used for controlling the second channel to communicate with the indoor channel. When the temperature of the outside air is low, the second channel communicates with the indoor channel, the cold air in the outdoor channel can be heated by the indoor hot air, and the defrosting effect is achieved. When the temperature of the outside air is high, the outside air can be humidified through a water supply device, and the using effect of the evaporative cooling unit is improved.

Description

technical field [0001] The present application relates to the technical field of air conditioning, in particular to an evaporative cooling unit and a data center. Background technique [0002] Evaporative heat sink is a conventional equipment in the field of heat dissipation. For example, in scenarios such as data centers or large buildings, evaporative heat sinks are required for heat dissipation. Taking the data center as an example, the data center uses indirect evaporative cooling equipment to dissipate heat. The indirect evaporative cooling equipment uses the principle of indirect evaporative cooling to dissipate heat. In order to achieve the effect of cooling the data center. In addition, in order to prevent outdoor impurities from entering the heat exchange device, a filter screen is installed in the indirect evaporative cooling equipment to filter the outdoor air. [0003] When in use, indirect evaporative cooling equipment can obtain cooling energy from the natura...
