Closed adiabatic air cooler

Abstract

The invention relates to a closed heat insulation air cooler which comprises an upper heat exchange chamber and a lower heat insulation chamber, wherein finned tube heat exchangers and spraying nozzles are mounted in the upper heat exchange chamber; the finned tube heat exchangers are arranged in a V-shaped manner; the lower heat insulation chamber comprises three corrugated fiber moistening boards which are arranged in an encircling manner to form a cavity; the cavity takes the shape of an inverted triangle, so as to form air intake surfaces, used for enlarging the air intake filtering surfaces and improving adiabatic humidifying and cooling effects, on two sides of a V-shaped structure. The air inlet of the air cooler is V-shaped, so as to enlarge the air intake area and improve the supply air rate of the air cooler, and further improve the integral heat exchange effect of the air cooler. The closed heat insulation air cooler comprises four working modes, namely a spraying evaporation cooling mode, an adiabatic humidifying evaporation cooling mode, a dry cooling mode and a natural cooling mode, which are controlled automatically through an electric control device, so that the air cooler can be in an optimal economical operation mode all the while, and electrical energy and water resources are saved.

Description

technical field [0001] The invention relates to a closed adiabatic air cooler, which uses air to cool the heat flow medium, and is mainly used for cooling the process circulating fluid of heating equipment such as industrial electric furnaces, power supplies and motors. Background technique [0002] Existing air coolers mainly include dry air coolers and dry-wet combined air coolers. Dry air coolers use ambient air as the cooling medium and rely on finned tubes to expand the heat transfer area to strengthen the heat transfer outside the tubes. The air temperature rise after traversing the finned tube takes away heat and achieves the purpose of cooling the fluid in the tube. It is characterized by simple operation and convenient use, but the temperature of the heat flow outlet in the tube depends on the air dry bulb temperature. Cooling does nothing. In order to make up for the shortcomings of dry air coolers, dry and wet combined air coolers have emerged. The working mechan...

AI Technical Summary

Problems solved by technology

The residue after the water evaporation of the dry-wet combined air cooler will adhere to the root of the finned tubes, resulting in fouling of the heat exchange coil, which will affect the heat exchange effect of the tube bundle after a period of use

Existing air coolers cannot be adjusted according to the external climatic conditions and the temperature of the fluid to be cooled. In transition seasons or cold seasons, the air coolers also run at full capacity, wasting electricity and water resources
