Plate heat exchanger (PHE) consists of a stack of corrugated metal plates, each featuring four corner ports to facilitate heat transfer between two fluids. These plates are assembled in a frame with a fixed plate and a movable clamping plate, secured by clamping bolts. Sealing gaskets on the plates define separate fluid channels, directing the fluids to flow alternately through adjacent spaces and enabling heat exchange. The corrugated surface enhances fluid turbulence and forms structural support points, ensuring the plate pack can withstand pressure differences between media while maximizing heat transfer efficiency.
Plates are suspended on upper guide rods and aligned by lower guide rods, with the frame’s end fixed to support columns. While single-pass configurations—where all pipelines connect to the fixed clamping plate—are most common, multi-pass setups (requiring interface openings on fixed or movable plates) are possible for specific applications. Unlike shell-and-tube heat exchangers, PHE plates are manufactured in standardized sizes using pressed tools (eliminating custom designs) but offer flexibility through adjustable plate counts and arrangements to meet diverse heat transfer duties.
As the most advanced energy-efficient heat transfer equipment, gasketed plate heat exchangers optimize performance through their compact design, turbulent flow dynamics, and modular construction, allowing easy maintenance (e.g., inspection or cleaning without pipeline disassembly by releasing clamping bolts).
