If the heat exchange medium outlet temperature continuously deviates from the set range during equipment operation, or if inspection reveals dust accumulation between fins causing increased pressure drop, this is often related to how well the heat exchanger selection matches the installation space, medium viscosity, and heat exchange load.
The plate-frame fin structure combines plate and fin channels, providing a large heat exchange area per unit volume, making it suitable for retrofit projects with limited space. During selection, the length, width, height, and nozzle orientation should be verified, space for core-pulling and cleaning should be reserved, and interference with adjacent piping should be avoided.
The nameplate should indicate design pressure, design temperature, heat exchange area, and medium flow direction, facilitating inspection personnel in verifying operating parameters. It is recommended to regularly record inlet and outlet temperature differences, pressure drop, and flow rate changes as a basis for judging scaling or blockage trends.
Suitable for scenarios such as hydraulic oil cooling, flue gas waste heat recovery, and HVAC water systems. When the medium contains particles or is prone to scaling, a filtration device should be installed at the inlet, and cleaning frequency should be appropriately increased.
