Honeycomb Type Evaporative Cooling Pad & Frame

How Honeycomb Type Evaporative Cooling Pad & Frame Filters Particles and Impurities in the Air

1. Honeycomb Structure Design
Airflow Channels: The honeycomb structure of the cooling pad is designed with multiple staggered airflow channels, so that the air flow direction changes multiple times when passing through the pad. This design not only increases the residence time of the airflow, but also causes the particles to settle due to the weakening of kinetic energy, reducing the passage of unfiltered air.
Increase Surface Area: The honeycomb structure has a larger surface area and can contact more air than a flat pad. This means that more particles are captured during the flow process, improving the filtration efficiency.
2. Cellulose Material Characteristics
High Adsorption: Cellulose materials that have undergone special chemical treatments have excellent adsorption and can effectively capture dust, pollen, bacteria and other tiny particles in the air. These treatments include adding hydrophilic substances to make the material perform better in a wet state.
Hydrophilicity: The hydrophilicity of cellulose allows moisture to diffuse in the material, thereby improving the filtration effect. Moisture not only captures particles, but also enhances adhesion to fine particles through the action of water film.
3. Layer-by-layer filtration mechanism
Multi-layer structure: Cooling pads are usually made of multiple layers of cellulose, forming a layer-by-layer filtration mechanism. Larger particles are captured in the outermost layer, while fine particles are further filtered in deeper layers.
Gradient pore size: The pore size design of cooling pads is usually gradually reduced from the outside to the inside. This gradual pore size helps to filter particles of various sizes more efficiently. Larger particles are captured first, and then smaller particles are further filtered in the next layer.
4. Fluid dynamic effect
Airflow disturbance: When air passes through the cooling pad, the disturbance caused by the structural design enhances the sedimentation of particles. This disturbance makes it easier for particles suspended in the air to contact the cellulose surface, increasing the probability of being captured.
Reduced speed: The airflow deceleration caused by the honeycomb structure makes it easier for particles to settle on the surface of the pad during the flow.
5. Humid environment
Water evaporation: During operation, the cooling pad absorbs water and produces moisture, which helps to adhere to particles in the air. The humid environment increases the adhesion between the particles and the surface of the pad, thereby improving the filtration efficiency.
Evaporative cooling: The evaporation of water absorbs heat during the evaporation process, and the resulting cold air can effectively reduce the temperature, further promote air flow, and is conducive to enhancing the filtering effect.
6. Regular maintenance and replacement
Regular cleaning: Keeping the cooling pad clean is an important measure to ensure its filtering effect. Regularly use a soft brush or vacuum cleaner to clean the surface of the pad to remove dust and prevent clogging.
Timely replacement: Replace the cooling pad in time according to the frequency of use and environmental conditions.
