Evaporative Cooling Pad working principle

Material and Structural Characteristics

The evaporative cooling pad uses special polymer materials and wood pulp fibers as its base material, forming a corrugated porous structure through molecular spatial cross-linking technology. Its core advantages are.

High Water Absorption:The point contact design between each fiber layer, combined with highly water-resistant adhesive materials, ensures that the structure remains sturdy even in high humidity environments and is not easily deformed after absorbing water.

Large Evaporative Surface Area:The corrugated structure significantly increases the surface area for water evaporation, improving heat exchange efficiency. For example, the 7090 type cooling pad has a thickness of 150-200mm, achieving more efficient cooling.

Low Wind Resistance Design:The porous structure reduces airflow resistance, ensuring minimal fan energy consumption. Experimental data shows that at a face wind speed of 1-1.5m/s, the resistance is only 10-15Pa, with a cooling efficiency of 80%.

Core Working Principle

Natural Cooling Through Water Evaporation The cooling principle of the evaporative cooling pad originates from the most basic physical phenomenon in nature—the heat absorption of water evaporation. Its core structure is made of porous paper material, which undergoes a special process to achieve excellent water absorption and air permeability. When outside air is drawn in by a fan and passes through the impregnated paper cooling pad, the moisture in the pad comes into full contact with the flowing air and evaporates rapidly. During this process, the moisture absorbs a large amount of heat from the air, causing the air temperature to drop rapidly. The cooled air is then sent into the room, thereby lowering the indoor temperature.
