Cellulose Evaporative Cooling Pads

Cellulose Evaporative Cooling Pads: A Comprehensive Analysis from Material Properties to Multi-Scenario Applications

I. The Technological Empowerment of Natural Fibers
Cellulose evaporative cooling pads are made from plant fibers (such as kraft paper and wood pulp) and formed into a porous honeycomb structure through a special process.

Efficient Water Absorption and Retention
The fiber surface is covered with micron-sized pores, allowing it to quickly absorb and store large amounts of water. For example, the 7090 cellulose cooling pad can absorb 60-70 mm of water in 5 minutes, holding 6-8 times its own weight in water, ensuring continuous evaporative cooling.

Low-Resistance Ventilation Design
The honeycomb channels or corrugated structure reduce airflow resistance by 30%-50%. At wind speeds of 1-1.5 m/s, the resistance is only 10-15 Pa, far lower than traditional materials, significantly reducing fan energy consumption.

II. Technical Principle: The Physical Wisdom of Evaporative Heat Absorption
The cooling mechanism is based on the wet-bulb effect: when unsaturated air flows over a moist cellulose surface, the water evaporates, absorbing sensible heat from the air, lowering the temperature. For example, in an environment with a dry bulb temperature of 35°C and a humidity of 20%, a high-quality cellulose pad can reduce the air temperature to 25-28°C while increasing the humidity by only 5%-8%, achieving gentle cooling.
