What is a Plate-Shell Heat Exchanger?
A Plate-Shell Heat Exchanger (PSHE) is a high-efficiency heat transfer device that combines the advantages of plate-type and shell-and-tube heat exchangers. Its core consists of a corrugated plate bundle enclosed in a pressure-resistant shell, offering both high heat transfer efficiency and high-pressure tolerance.
Key Features
High Heat Transfer Efficiency: Corrugated plates induce turbulence, achieving 3–5x higher heat transfer coefficients than shell-and-tube exchangers.
Compact Design: High surface-area-to-volume ratio saves space.
High-Pressure Capability: Shell withstands pressures exceeding 10 MPa, far beyond conventional plate heat exchangers (typically ≤2.5 MPa).
Vibration & Thermal Stress Resistance: Fully welded plate bundles suit harsh environments (e.g., ships, chemical plants).
