How does the staggered corrugated design of the Cooling Pad for 18 In. Evaporative Coolers improve cooling efficiency? How is it different from traditional flat designs?

1. Increased surface area
Staggered corrugated design:
The staggered corrugated structure used in the Cooling Pad for 18 In. Evaporative Coolers significantly increases the surface area of ​​the pad through a curved and tilted design. This means that more air and water can come into contact with the surface of the cooling pad, enhancing the evaporation process of water and thus improving cooling efficiency.
Traditional flat design: The surface area is relatively small, and the contact time and contact area between the air and the cooling pad are limited, so the evaporation efficiency is low and the cooling effect brought by the evaporation of water cannot be fully utilized.
2. Optimized air flow path
Staggered corrugated design: The corrugated structure guides the air to form a tortuous flow path in the cooling pad. This complex air flow can increase the residence time of the air and ensure that the air and water are in more contact. Longer contact time helps the air absorb more water, thereby improving the effect of evaporative cooling.
Traditional flat design: air passes through the cooling pad in a relatively straight line, and the contact time between air and water is shorter, resulting in evaporation efficiency that is not as high as the corrugated design.
3. Improve the uniformity of moisture distribution
Staggered corrugated design: This structure helps water to be evenly distributed on the surface of the cooling pad, avoiding the problem of water accumulation or loss too quickly on the surface of the pad. The uniform moisture distribution ensures that every part of the cooling pad can effectively participate in the evaporation process, thereby improving the overall cooling performance.
Traditional flat design: moisture may be unevenly distributed on the pad, and some areas may be overly dry or wet, resulting in uneven cooling effect and affecting overall performance.
4. Enhanced air filtration effect
Staggered corrugated design: The corrugated structure not only improves cooling efficiency, but also enhances air filtration effect. Large particles of impurities and pollutants in the air will be blocked or adsorbed by the corrugated structure of the cooling pad, providing cleaner air input for the evaporative cooler and extending the service life of the equipment.
Traditional flat design: Due to the simple structure, the air flows faster, impurities can easily pass through, and the filtration effect is weaker.
5. Reduce airflow resistance
Staggered corrugated design: Although the air flow path is more complicated, the corrugated structure can effectively control the airflow resistance through optimized design, ensuring that the cooler fan will not increase the load due to excessive resistance, and maintain the efficient operation of the equipment.
Traditional flat design: Although the air flow path is more direct, the air contact effect is not as deep as the corrugated design, and it cannot effectively improve the cooling efficiency.
