Abstract:
The present application 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 disposed in the outdoor channel; the defrosting device is located on the side of the filter screen close to an air inlet of the outdoor channel; the defrosting device comprises a heat exchange film; a first channel and a second channel arranged in a cross are provided in the heat exchange film; the first channel is communicated with the air inlet of the outdoor channel; the second channel communicates with the indoor channel; the first channel communicates with the second channel; the defrosting device further comprises a switching valve; the switching valve is used for controlling the communication between the second channel and the indoor channel. When the temperature of outside air is low, the second channel is communicated with the indoor channel, and indoor hot air can heat cold air in the outdoor channel, thereby achieving a defrosting effect. When the temperature of the outside air is high, the outside air can be humidified by means of a water supply device, thereby improving the use effect of the evaporative cooling unit.
