I. Product Structure and Working Principle

1. Core Structure

• Heat Exchange Plates: Made of stamped thin metal sheets with corrugated grooves on the surface (to enhance heat transfer efficiency and structural rigidity), serving as the core carrier for heat transfer;
• Sealing Gaskets: Installed around the plates to seal gaps between plates, prevent medium leakage, and assist in dividing flow channels;
• Clamping Assembly: Includes clamping studs and other components, which fix all plates through clamping force to ensure the overall sealing performance and structural stability of the equipment.

2. Working Process

• Medium Distribution: Two fluids to be heat-exchanged (hot medium and cold medium) enter their respective dedicated channels from the equipment inlets and are distributed into independent flow channels between the plates (separated by sealing gaskets to avoid cross-flow);
• Countercurrent Heat Exchange: Under normal circumstances, the hot medium and cold medium flow in countercurrent in the flow channels (to maximize temperature difference and improve heat transfer efficiency), and the hot medium transfers heat to the metal plates;
• Heat Transfer: The plates act as intermediate heat-conducting carriers, transferring the absorbed heat to the cold medium on the other side;
• Temperature Regulation: Finally, the temperature of the hot medium decreases (achieving cooling), and the temperature of the cold medium increases (achieving heating), thus completing the heat exchange goal.

II. Core Product Features

1. Advantageous Features

• High Heat Transfer Efficiency: The corrugated-groove plates expand the heat transfer area, disrupt the fluid boundary layer, and combined with the countercurrent heat exchange design, the heat transfer coefficient is significantly higher than that of traditional heat exchangers;
• Easy Maintenance: Plates can be separated by disassembling the clamping assembly, facilitating inspection and cleaning (Note: With the development of THE-type heat exchanger technology, this advantage has relatively diminished);
• Low Fouling Impact: Fluids flow in a turbulent state in the corrugated flow channels, making it difficult for fouling to accumulate. The fouling coefficient is low, reducing the need for frequent cleaning;
• Compact Structure: Adopts a plate-stacking design, featuring small floor space and light equipment weight, saving installation space;
• Strong Flexibility: The heat exchange area can be adjusted by increasing or decreasing the number of plates, or the process can be optimized by changing the plate combination method, adapting to different working condition requirements;
• High Heat Exchange Precision: Small end temperature difference (small temperature difference between the outlets of hot and cold media), enabling more precise temperature control.
