Direct evaporation type heat exchanger

Abstract

The invention provides a direct evaporation type heat exchanger which is composed of multilayer corrugated fibers, wherein the corrugation wave height is 5mm and the corrugations are staggered and opposed at 90 degrees. The invention has the beneficial effects that: the contact area is large, the evaporation efficiency is higher, and the cooling effect is better; the multilayer corrugated fiber superimposed wet screen has good filterability on fine dust in the air; the surface of the wet screen washed by tap water forms a water film and can be cleaned automatically, thus achieving cleaning and cooling effects, and water in a fan can be circularly used to reduce waste of water resources; and the wet screen paper does not contain chemical substances such as phenol and the like which are easy to cause skin allergy, so that the wet screen paper is nontoxic and harmless to the human body when installed and used, and is green, safe, energy-saving, environment-friendly, economic and applicable.

Description

Technical field [0001] The invention belongs to the field of heat exchange, and particularly relates to a direct evaporation heat exchanger. Background technique [0002] In the existing technology, the wet curtain fan cooling system has been widely used in agriculture, textile factories in high-temperature workshops, and places that need to cool down and adjust humidity. In agriculture, it is often used in greenhouses and livestock and poultry houses to cool down, and they have achieved good results. The wet curtain is mainly made of special polymer materials and wood pulp fibers in a minute space cross-linking, and is made of high water resistance and strong weather resistance materials to ensure other It has sufficient wet stiffness, high water absorption performance, large evaporation specific surface area and low flow resistance loss. It uses water to evaporate to convert the sensible heat in the air into latent heat. Although the cooling effect is good, the existing In the...

Problems solved by technology

In agriculture, it is often used in greenhouses and livestock and poultry houses to cool down, and all have achieved good results. The wet curtain is mainly made of special polymer materials and wood pulp fibers that are cross-linked in a minute space, and cemented with high water resistance and strong weather resistance materials to ensure it. It has sufficient wet stiffness, high water absorption performance, large evaporation specific surface area and low flow resistance loss. When water evaporates, it converts the sensible heat in the air into latent heat. Although its cooling effect is good, the existing In the actual use of wet curtain products, the water absorption and ventilation performance are not very good, and the actual heat dissipation area is not large enough
