putkilämpönvaihdin

Putkilämpönvaihdin is a Finnish term referring to a shell and tube heat exchanger. This common type of heat exchanger consists of a bundle of tubes inside a larger cylindrical shell. One fluid flows through the tubes, while another fluid flows over the tubes within the shell. Heat is transferred between the two fluids through the tube walls.

Shell and tube heat exchangers are widely used in various industrial applications due to their robustness, flexibility, and ability to handle high pressures and temperatures. They are found in power plants, chemical processing facilities, HVAC systems, and refrigeration units. The design can be adapted for different purposes by varying the number of tubes, shell diameter, tube material, and baffling.

The efficiency of a putkilämpönvaihdin depends on factors such as the temperature difference between the fluids, the flow rates, the surface area for heat transfer, and the thermal conductivity of the tube material. Maintenance is crucial to prevent fouling, corrosion, and leaks, which can reduce performance and lifespan. Regular cleaning and inspection are standard procedures for ensuring optimal operation.
