What is a honeycomb sheet? How important is it?
A honeycomb sheet is a cooling pad made from various materials depending on the manufacturer’s brand, including cellulose fibers, paper pulp, and glass fibers. It is a square sheet with a wave pattern designed with holes to help air flow through and water permeability. It also helps to make cleaning easy. It is considered one of the most important components of an evaporative fan because it absorbs water from the water tank to distribute water across the surface of the sheet. When you turn on the evaporative fan, the hot air outside that is sucked into the honeycomb sheet turns the water into vapor and helps reduce the water temperature, giving you cool wind. It also helps purify the air, traps dust and air pollution, and reduces the problem of allergies.
! Maintenance of honeycomb panels
clean regular
1. honeycomb c clean water
– ไม่ใช่ low-pressure cleaning agents
– หรือใช้ soft brush moistened c water เพื่อ remove dust , dirt ใน crevices-รอยแยก
– hole สัปดาห์ละครั้ง และไม่ expose sunlight
– dry ,well-ventilated area จน complete dry
2. replace ทุก 1-2 yr , เมื่อ sheet deteriorate , rotten, musty smell , air coming out , ไม่เย็นย
3. water tank- fill c clean water
wash regular

1. Antibacterial and Antifungal Coatings:
- Copper-Based Coatings: Copper also has strong antibacterial and antifungal properties. Copper ions disrupt the cell walls of bacteria and fungi, preventing their growth on the surface of the pad.
- Polymeric Coatings: Some manufacturers use special polymeric coatings that include antimicrobial agents to create a barrier that prevents the buildup of bacteria and fungi.
2. Deodorizing Coatings:
- Activated Carbon: A common deodorizing substance is activated carbon. This material adsorbs impurities, odors, and volatile organic compounds (VOCs), helping to neutralize unpleasant smells in the air that might pass through the cooling pad.
- Zeolite: Another substance used for deodorization is zeolite, a natural mineral that absorbs moisture and neutralizes odors, helping to keep the air cleaner and fresher.
3. Honeycomb Design Modifications:
- 2-Layer Honeycomb Sheets: Some cooling pads use a two-layer honeycomb design to improve airflow, moisture distribution, and cooling efficiency. The inner layer may be made from a more durable material, while the outer layer is designed for maximum evaporation.
- Larger Honeycomb Holes: Increasing the size of the holes in the honeycomb structure can allow more air to flow through the pad, improving cooling efficiency. However, the size of the holes needs to be balanced with the ability of the pad to hold water and prevent it from drying out too quickly.
4. Waterproof Coatings:
- Hydrophobic Coatings: Some cooling pads are treated with hydrophobic (water-repelling) coatings to help prevent water from evaporating too quickly, ensuring that the cooling process is effective over a longer period.
Manufacturing Process for Coating:
- Spraying or Dipping: The cooling pads are often coated with these substances through spraying or dipping during the manufacturing process. The coating is typically applied to the pad material before it is assembled into the final cooling unit.
- Heat Curing: After the coatings are applied, the pads may undergo a heat curing process to bond the coatings to the material, making them durable and long-lasting.
By incorporating these technologies, manufacturers can create cooling pads that offer enhanced air quality, longer durability, and improved efficiency, catering to the evolving needs of consumers and adapting to various environmental conditions.
