Plate-fin heat exchanger: a heat exchange device carefully constructed of plates and fins. Its key components include baffles, fins, seals and guide vanes. Fins, guide vanes and seals are cleverly placed between adjacent baffles to form a sandwich, which is called a channel. By stacking multiple such channels in different ways of fluid flow and connecting them into a whole using a brazing process, a plate bundle is formed. As the core part of the plate-fin heat exchanger, the plate bundle is equipped with necessary headers, pipes, supports and other components to complete the overall assembly of the plate-fin heat exchanger.
Plate fin heat exchangers have a wide range of applications, a few of which are:
A Plate-Fin Heat Exchanger (PFHE) is constructed from alternating layers of flat metal plates and corrugated fins, creating a series of parallel channels for fluid flow. Hot and cold fluids flow through adjacent channels in either a countercurrent (opposite directions) or crossflow (perpendicular directions) arrangement. Heat transfers through the metal plates and fins via conduction: the high-temperature fluid releases heat to the plates and fins, where the corrugated design—featuring shapes like triangular, sine, or sawtooth—increases surface area and induces turbulence to enhance heat transfer. The low-temperature fluid in the neighboring channel absorbs this heat, completing the exchange process. Diverters and sealing strips at the channel ends prevent fluid mixing, while headers or joints connect the inlets and outlets. Fin height and channel design can be optimized to improve heat exchange efficiency and minimize pressure loss.
Plate-fin heat exchangers offer distinct advantages for efficient thermal management. The corrugated fins boost surface area and turbulence, delivering 30%-50% higher heat transfer efficiency than traditional heat exchangers, making them ideal for gas-to-gas or gas-to-liquid applications. Their compact, lightweight design—typically 1/3 to 1/5 the size and weight of shell-and-tube exchangers—supports multi-fluid heat exchange (up to 10+ fluids) for complex systems. Constructed from aluminum alloy or stainless steel, PFHEs withstand high temperatures (up to 650°C) and pressures (up to 100 bar), with optimized channels reducing pressure drop for low-pressure scenarios. The brazed structure minimizes leaks, turbulence reduces fouling for less maintenance, and customizable fin shapes and materials ensure versatility across aerospace, petrochemical, and refrigeration industries.
