What is an evaporative cooling pad?

Farm cooling pad is a common cooling equipment its working principle is mainly through the evaporation of water to absorb the heat in the air, so as to achieve the effect of cooling. Cooling pad system consists of cooling pads, pumps, water pipes, nozzles and drainage systems.
Cooling pad is made of several water pipes arranged in parallel, the two ends of the water pipe through the connection pipe connected to a circulating water circuit. The water pump pumps water out of the circulating water circuit, through the nozzle sprayed on the water curtain, forming a thin film of water. When the hot air passes through the cooling pad, the water film will absorb the heat in the air, and the water base will be sent off, thus making the air temperature drop.
The working principle of the cooling pads can be explained by the process of water evaporation. According to the laws of thermodynamics, water molecules need to absorb or release heat to switch between liquid and gas states. When water evaporates, the water molecules change from a liquid state to a gas state, requiring the absorption of heat from the surrounding environment. When hot air passes through the water curtain, the heat in the air is transferred to the water film, which causes the water molecules to evaporate and the air temperature to drop
The effectiveness of an evaporative cooling pad system is affected by a variety of factors, such as water flow rate, water temperature, air temperature, humidity, and wind speed. The higher the flow of water, the better the cooling pad cooling effect. The lower the temperature of the water, the stronger the ability to absorb heat and the better the cooling effect. The higher the temperature and the lower the humidity, the better the cooling effect. The higher the wind speed, the faster the water film evaporates and the better the cooling effect.

WUSEN Plastic Evaporative Cooling Pad is a new product produced by polypropylene injection molding, which is optimized based on the application of paper cooling pads. Plastic cooling pads not only have the cooling effect of paper cooling pads, but also have the characteristics of water corrosion resistance, non mold and insect resistance. Their normal service life can reach more than 10 years. Due to the long service life of plastic liners, there is no need to replace the liners during use, greatly reducing the material costs and high labor costs that customers pay for replacing the liners.
