What’s a plate coil?

Plate coils are flat metal plates welded together with a fluid flow channel between them to absorb or diffuse heat energy. They offer larger heat radiating surfaces, flexible shaping, and space-saving features. The plates can be rolled into cylinders as small as 12 inches in diameter, making them a flexible and efficient heat transfer option.

A plate coil is a heat transfer device that uses flat metal plates welded together with a fluid flow channel between them to absorb or diffuse heat energy. The plate coil heat exchanger design offers several distinct advantages over stacked plate and tube coil designs, including larger heat radiating surfaces, flexible shaping, and space-saving features. Depending on system requirements, coils of plate can be stacked together to form modular units or formed to fit drums or pipes. The plates can be rolled into cylinders as small as 12 inches (30cm) in diameter, thus making the plate coil a flexible and efficient heat transfer option.

The introduction or removal of heat from an environment or material is usually achieved by heat transfer or exchange. This concept underlies all air and fluid conditioning systems and works on the principle of allowing a medium, usually a liquid or gas, to absorb heat from one place and move it to another. Heat exchangers typically use water to effect this transfer of thermal energy. Most work by channeling water through a series of pipes or vessels where they absorb or spread heat across surfaces in the flow path. Obviously the greater these surfaces, the greater the transfer area and the better the exchanger will work.

The plate heat exchanger takes advantage of this concept by using flat stainless steel or titanium plates that are embossed with a predetermined pattern on one or both sides. When these patterns are aligned with those on a second plate, they form a channel or flow path between the plates. This channel has two exit points from the indoor area which are equipped with inlet and outlet fittings. When water is circulated through the channel, it effectively uses both the channel and the entire plate surface as a radiant mechanism to spread or absorb heat. This design allows for large radiating areas in an assembly with flat and compact physical dimensions.

Another advantage of plate coil is its flexibility in forming. The plates can be stacked together to form modular stacks and the plates themselves can be formed into different shapes depending on the application. As noted above, barrel plate coil assemblies can be stacked concentrically in drums, tanks, or pipes up to 12 inches (30 cm) in diameter. This allows for maximum use of most internal profiles, while still allowing for good flow patterns and optimal exposure and heat transfer. Plate coils are also quite easy to maintain and replace as needed, thus further increasing their value as efficient heat transfer mechanisms.
