Honeycomb Evaporative Cooling Pad

The Honeycomb Evaporative Cooling Pad is a structured cooling medium designed for direct evaporative cooling in livestock buildings, poultry houses, greenhouses and other agricultural facilities. Its three-dimensional corrugated structure creates a large effective contact area between water and incoming air.

During operation, water is distributed across the upper part of the cooling pad and moves downward through the structured media. Warm outdoor air is drawn through the wet pad by the ventilation system, allowing part of the water to evaporate and absorb heat from the passing air.

The cooling pad can be installed at the fresh-air intake side of tunnel or negative-pressure ventilation systems. When combined with exhaust fans, water distribution pipes, circulation pumps and collection troughs, it becomes an important component of a complete livestock ventilation system.

Pad dimensions, thickness, material and configuration can be selected according to airflow requirements, building design, local climate, water quality and project conditions. This makes the product suitable for new livestock facilities as well as existing ventilation-system upgrades.

• Honeycomb Airflow Structure: Provides extensive contact between incoming air and the wetted cooling surface.
• Evaporative Heat Exchange: Uses the natural heat-absorption effect of water evaporation to cool incoming air.
• Large Contact Surface: The corrugated structure increases the effective air-water interaction area.
• Continuous Wetting: Designed to support consistent water distribution through the cooling media.
• Fresh-Air Cooling: Helps reduce the temperature of outdoor air before it enters the livestock building.
• Suitable for Negative-Pressure Ventilation: Compatible with tunnel and negative-pressure ventilation layouts.
• Modular Installation: Individual pad sections can be combined into larger cooling-wall assemblies.
• Material Flexibility: Cellulose and plastic cooling media can be selected according to project requirements.
• Wide Agricultural Application: Suitable for pig, poultry, cattle, greenhouse and other controlled agricultural environments.
• Project Customization: Product dimensions and configuration can be designed according to ventilation calculations.

• Evaporative Cooling Media: Corrugated or honeycomb material forms the main heat-exchange surface.
• Airflow Channels: Internal passages guide outdoor air through the wetted media.
• Water Absorption Surface: Provides the wetted area required for evaporation.
• Upper Water Distribution Area: Receives water from the distribution pipe or header.
• Lower Drainage Area: Allows excess water to leave the cooling media.
• Supporting Frame: Holds the cooling-pad modules securely within the cooling-wall opening.
• Water Collection System: Optional trough or gutter collects unused water for recirculation.
• Sealing Elements: Help minimize air bypass around individual pad modules.

The Honeycomb Evaporative Cooling Pad operates through direct evaporative heat transfer. Water is supplied to the upper section of the pad and flows downward through the structured media, creating a continuously wetted surface.

When exhaust fans create negative pressure inside the building, warm outdoor air is drawn through the wet cooling pad. As the air passes through the honeycomb channels, part of the water evaporates and absorbs heat from the air, resulting in cooler and more humidified incoming airflow.

Unevaporated water continues downward and can be collected through a lower trough before being returned to the circulation system. The structured media provides a controlled airflow path while maintaining extensive contact between air and water.

Actual cooling performance depends on outdoor temperature, relative humidity, airflow velocity, water distribution and the complete ventilation-system design.

2. Prepare a structurally suitable opening and supporting frame for the cooling-pad modules.
3. Install the cooling pads according to the designed airflow direction.
4. Align adjacent modules carefully to minimize air leakage and bypass.
5. Install the upper water distribution pipe or header above the cooling pads.
6. Connect the water distribution system to the circulation pump and collection system.
7. Ensure that the lower drainage section is unobstructed.
8. Seal unnecessary gaps around the cooling-wall frame.
