PARTS OF PLATE HEAT EXCHANGER
- Plates: The most important part. They are thin plates stamped from corrosion-resistant metals (like stainless steel, titanium, or aluminum) with a corrugated (wavy) pattern. This pattern creates turbulence in the fluids and provides structural support.
- Gaskets: Rubber seals that sit in grooves around the edge of each plate. They prevent the fluids from leaking to the outside and ensure they flow in the correct alternate channels. (Note: Some are brazed or welded instead of gasketed).
- Frame: A fixed frame plate and a movable pressure plate that hold the entire pack of plates together under pressure with large tightening bolts.
- Ports: Inlet and outlet holes at the corners of the plates that align to form continuous passages for the two fluids to enter and exit the plate pack.
