Plate and Channel Design
BPHE type B utilizes two types of plates and three types of channels, influencing thermal characteristics:
Plate Types:
- H type plate: Features obtuse angles, increasing fluid turbulence for higher heat transfer efficiency.
- L type plate: Features acute angles, reducing pressure drop and turbulence, leading to lower heat transfer efficiency.
Channel Types:
- H channel: Made by two H plates, offering high heat transfer coefficient and high pressure drop.
- L channel: Made by two L plates, offering lower heat transfer coefficient and lower pressure drop.
- M channel: Made by one H plate and one L plate, providing medium pressure drop and heat transfer coefficient.
Diagram Description: The structure of a BPHE shows corrugated plates forming flow channels. Key components include front/back cover plates, tail pieces, refrigerant channels, water channels, and mounting bolts. Adaptors can feature temperature transmitter ports.
