Regeneration type evaporative cooler

Abstract

The invention discloses a regenerative evaporative cooler. The cooling unit is composed of a dry channel and a wet channel arranged in the cooling unit so as to be in close contact with each other. A portion of the initial air is separated at the end to form separated air that flows in a direction opposite to that of the initial air in the wet channel. Multiple cooling radiators are arranged in the dry and wet channels to improve water evaporation efficiency and water evaporation area in the wet channels. The first blower draws initial air into the dry channel, and the second blower draws a portion of the initial air from the dry channel into the wet channel to form separated air. The water supply unit supplies water to the wet passage. In the cooler of the present invention, the separated air flowing in the wet channel absorbs the heat of the dry channel through the fins of the wet channel to cool the initial air flowing in the dry channel.

Description

technical field [0001] This invention relates to an evaporative cooler designed to distribute a flow of cold air cooler than the outside air into a target room without the use of refrigerant, unlike conventional air conditioners, and more particularly to a Regenerative evaporative coolers designed to use the latent heat of water evaporation to reduce the temperature of incoming air before it is distributed into the intended room. Background technique [0002] As is well known to those skilled in the art, evaporative coolers spray water onto the air flowing in the channels, thereby causing the water to evaporate to absorb latent heat from the air and thus make the air cool before it is distributed from the cooler to the target room. get cooler. Various types of evaporative coolers have been proposed and used in the prior art. For example, Korean Patent Publication No. 961649, and U.S. Patents 3,792,841 and 4,337,216 each disclose direct-type evaporative coolers that spray w...

Problems solved by technology

However, when increasing the size of the thermally conductive plates as described above, it is difficult or almost impossible to maintain the ideal 1-2 mm gap between the enlarged thermally conductive plates

As a result, the heat transfer plates may locally contact each other, or the gap between them becomes large, resulting in uneven distribution of airflow, reducing the effective heat transfer area and effective heat transfer rate, and reducing the operating performance of the regenerative evaporative cooler
