Evaporative Cooling Pads: Principle and Structure

I. Material Characteristics: A Perfect Combination of Natural

Environmental Protection and Highly Effective Water Absorption The core material of the paper evaporative cooling pad is specially treated corrugated wet-strength paper. This paper, made from natural plant fibers using advanced production processes, not only retains the natural environmental properties of paper but also endows it with superior physical properties.

High Absorbency Corrugated wet-strength paper has extremely high water absorption, quickly absorbing and locking in large amounts of moisture. When air flows over the moistened surface of the cooling pad, the moisture on the pad evaporates rapidly, absorbing heat from the air and achieving a cooling effect. This high absorbency ensures that the cooling pad can continuously provide a moist evaporation surface during long-term use, maintaining stable cooling performance.

Structural Design The paper evaporative cooling pad adopts a unique corrugated structure design. This design not only increases the heat exchange surface area and improves evaporation efficiency but also reduces ventilation resistance, allowing for smoother airflow. The corrugated structure also guides the water flow to distribute evenly, ensuring that all parts of the cooling pad are fully moistened, further improving the cooling effect.

II. Working Principle: Evaporation and Heat Absorption, Natural Cooling The working principle of the paper evaporative cooling pad is based on the phenomenon of evaporative heat absorption in physics. When air flows over the moist surface of the cooling pad, the moisture on the pad evaporates rapidly. The evaporation process requires the absorption of heat from the air, thereby lowering the air temperature. This process requires no compressor or refrigerant; it relies solely on the natural evaporation of water, resulting in extremely low energy consumption.

In practical applications, the paper evaporative cooling pad is typically used in conjunction with a negative pressure fan. The negative pressure fan extracts hot air from the barn or workshop while simultaneously introducing fresh outside air. This fresh air experiences a significant temperature drop as it flows over the moist paper evaporative cooling pad and is then circulated into the barn or workshop, creating a beneficial air circulation. This cooling method not only effectively lowers the ambient temperature but also increases air humidity, creating a more suitable growing environment for livestock or plants.
