Plate Heat Exchanger Working Principle

Working Principle

The demountable plate heat exchanger is an efficient heat exchange device with alternating metal corrugated plates, forming cold and hot channels through rubber gaskets for full counter-current heat exchange.

2. Features

1) Compact and Space-Saving: The structural design of the demountable plate heat exchanger is compact, with a smaller overall size. Compared to shell-and-tube heat exchangers, it can save 50%-80% of space. Online teaching at Shangtian Niao Education's HVAC design, Teacher Du

2) Energy-saving & Efficient: Under the same working conditions, less cooling medium is required. Therefore, less propulsion power is needed when conditions are identical.

3) Diverse Material Options: Choose the appropriate material for the plate based on the acidity or alkalinity of the user's medium to meet the lifespan requirements of the user's product.

4) Low maintenance and repair costs: Modular design for easy post-maintenance, with the option to replace individual modules for greater cost-effectiveness. Additionally, the removable plate heat exchangers can be easily opened for cleaning. Moreover, the cleaning agents used for surface cleaning can be high-pressure water (or acid solutions for special working environments).

3. Key Technologies

1) Plate Fluid Distribution Design: Incorporating分流, 导流, and heat exchange zones, this design reduces drawbacks such as decreased heat exchange efficiency, increased flow dead zones, and a higher tendency for localized scaling due to uneven flow distribution.

2) Sheet Contact Design: The wavy peak-valley surface contact design between the sheet's guidance and heat exchange areas plays a crucial role in enhancing the sheet heat exchange efficiency.

3) Diverse Channel Designs: The H, L size angles of the plates, as well as the B, M width and narrow channel designs, allow for better utilization of different fluid media states, and reasonable adjustment of flow rate, pressure drop, and the intensity of heat transfer.

4) The design of clip, cross-section, leakage cavity, and double sealing for gaskets effectively addresses issues such as strength, sealing, and compactness that arise from the squeezing of plates.
