Pillow Plate Heat Exchanger for Immersion Cooling

Pillow Plate Heat Exchanger for immersion cooling

Pillow plate heat exchangers for immersion cooling are high-efficiency, laser-welded stainless steel panels submerged directly into a liquid bath to cool fluids, gases, or solids. These custom-shaped plates offer excellent turbulence, high heat transfer coefficients, and are easy to clean, making them ideal for industrial, food, chemical, and pharmaceutical applications.

Key Aspects of Pillow Plate Immersion Cooling:

Design & Structure: Formed by welding two metal sheets (often stainless steel 304/316) with a specific pattern, then inflating them to create internal channels for cooling media like water, glycol, or refrigerant.

Application: Used individually or in "banks" (multiple plates) inside tanks to cool liquids, often utilized in batch processes to maintain temperature.

Benefits:

High Efficiency: The welding pattern creates high turbulence, optimizing heat transfer.

Low Fouling & Easy Cleaning: Open systems with relatively flat surfaces facilitate easy maintenance.

Durability: High resistance to pressure and temperature without gaskets.

Customization: Plates can be custom-made in various shapes, sizes, and configurations to fit specific vessels.

Performance Enhancement: Agitation (e.g., pumps, mixers) around the plates significantly improves the heat transfer coefficient.

Pillow plates are often used as an alternative to shell-and-tube or traditional coil exchangers for superior cooling performance in, for example, industrial chillers or cooling for food and beverage products.
