Title:
INDIRECT EVAPORATIVE COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/110670
Kind Code:
A1
Abstract:
An indirect evaporative cooling device (10). A filter screen (200) and a wet film (300) are arranged on an outdoor air-intake transition section (150), the wet film (300) is arranged on the side of the filter screen (200) away from an outdoor air inlet (170) of a heat exchange core (100), and a water inlet of the wet film (300) is in communication with a water storage device (400), such that the wet film (300) is first used for filtering large-sized debris such as catkin and large-particle sand dust in outdoor air, and then the filter screen (200) is used for finely filtering small-sized debris such as small-particle sand dust; and when the wet film (300) is blocked, a water source can be directly provided for the wet film (300) by means of the water storage device (400) so as to rinse the wet film (300), thereby simplifying the maintenance procedure of the wet film (300), reducing the difficulty and costs of subsequent maintenance of the indirect evaporative cooling device, and also further preventing the blockage of the filter screen (200) due to filth in the short term, prolonging the service life of the filter screen (200), and reducing the maintenance costs of the filter screen (200).
