Abstract

The invention discloses a wet curtain for an evaporating type cooling fan and a preparation method of the wet curtain. The wet curtain for the evaporating type cooling fan is formed by adhering wave-shaped water absorbing radiating plates which are coated with magnetic / electric resin compositions, wherein the magnetic / electric resin compositions include magnetic power, tourmaline powder and heat convertible resin. According to the wet curtain for the evaporating type cooling fan, the surface is provided with the magnetic and electric functional coating, so that the surface tension of water can be reduced, the steam pressure can be reduced, and therefore, the water evaporating rate can be obviously increased, and the cooling is sped up.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a wet curtain for an evaporative cooling fan and a preparation method thereof. Background technique [0002] Evaporative cooling fan (also known as "air conditioning fan") is a system that uses the principle of water evaporation to ventilate, humidify and cool indoor air. Its core component is a honeycomb wet curtain placed in it. Fiber paper is prepared by dipping, drying, corrugating, bonding and other processes. When the air-conditioning fan is working, the air in the environment is drawn into the air-conditioning fan, and when the air flows through the porous and humid wet curtain, a large amount of water on the surface of the wet curtain evaporates, and the heat reflected by the temperature in the air is converted into the latent heat of evaporation, thereby reducing the The temperature of the air itself, the air-conditioning fan will introduce the cold air cooled ...
