The pillow plate consists of two stainless steel sheets that are laser welded together by welding a custom circular weld pattern. The inflation process pressurizes the two sheets, deforming the material and forming a cavity for the heat transfer medium. This inner cavity facilitates efficient fluid flow and heat transfer, enabling the pillow plate to handle liquids, vapors, or refrigerants effectively.
In addition to the inner channel, the space between adjacent pillow plates (outer channel) also allows fluid to flow. This enables heat exchange with external mediums, ensuring uniform temperature distribution and optimizing the overall heat transfer process.
This dual-channel design-combining inner and outer fluid pathways-makes pillow plates a compact and efficient heat exchanger solution for industrial cooling, heating, and energy recovery applications.
How Pillow Plate Heat Exchangers Operate?
Connecting pipe work to single and double plates necessitates careful layout to mitigate tensions from thermal and mechanical expansion, ensuring panel connections remain intact. Proper support for pipe work weight is essential, often achieved through suitable supports or expansion bends/joints.
For efficient heat transfer or uniform temperature distribution within tanks, installing double-profiled panels directly within the tank proves beneficial. These panels also serve as guide surfaces in tanks with agitators, facilitating optimal mixing and homogeneous heating or cooling.
Pillow plates offer unparalleled reliability and durability, capable of withstanding high pressures while maintaining structural stability. Their automated manufacturing process ensures flexibility, making them ideal across a spectrum of applications. Additionally, their ability to operate at extreme temperatures further enhances their suitability for demanding industrial processes.
