How Does a Cooling Pad Making Machine Work? Working Principle Explained

In modern industrial ventilation and evaporative cooling systems, the cooling pad making machine plays a key role in producing high-efficiency evaporative cooling pads widely used in greenhouses, livestock farms, industrial workshops, and HVAC cooling systems.

As global demand for energy-saving cooling solutions continues to increase, understanding the working principle of a cooling pad production machine helps manufacturers improve production efficiency and product quality.

What Is a Cooling Pad Making Machine?

A cooling pad making machine is an automated industrial production line designed to manufacture evaporative cooling pads (also known as wet curtains or cooling pad paper).

These cooling pads are made from:

• High-strength kraft paper

• Special anti-corrosion resin

• Water-absorbing fiber materials

The machine converts raw paper into a corrugated honeycomb structure, which provides excellent water absorption and air cooling performance.

How Does a Cooling Pad Making Machine Work?

The working process is a continuous automated system that includes paper feeding, corrugation, glue coating, stacking, pressing, and drying.

1. Paper Feeding Process

The production begins with kraft paper rolls being automatically fed into the machine.

• Paper rolls are unwound continuously

• Tension control ensures stable feeding

• Multi-layer paper preparation for forming

This ensures smooth and uninterrupted production.

2. Corrugation Process (Wave Forming)

The paper passes through corrugation rollers to form wave shapes.

• Heated rollers shape the paper into a corrugated structure

• Different roller designs control wave height and angle

• Increases surface area for better cooling efficiency

This step determines the core structure of the cooling pad.

3. Glue Coating Process

After corrugation, a special adhesive is applied.

• Uniform resin glue coating system

• Controlled glue thickness

• Ensures strong bonding between layers

This improves durability and water resistance.

4. Stacking and Pressing Process

Corrugated sheets are stacked and pressed into a honeycomb structure.

• Sheets are arranged in cross-direction (45°–90° angles)

• Hydraulic or mechanical pressing system

• Forms a stable and uniform structure

This structure is essential for evaporative cooling performance.

5. Drying and Curing Process

The final stage is drying and curing.

• Material passes through a drying system

• Moisture is removed completely

• Resin is fully cured and hardened

After this process, the cooling pad becomes strong and ready for cutting and packaging.
