putkilämmönsiirtimessä

A putkilämmönsiirrin, or tubular heat exchanger, is a device used to efficiently transfer heat between two fluids. These fluids can be liquids or gases, and they are kept separate by a series of tubes. The heat exchanger consists of a shell or casing that encloses a bundle of tubes. One fluid flows through the inside of the tubes, while the other fluid flows over the outside of the tubes, within the shell. Heat is conducted through the tube walls from the hotter fluid to the colder fluid.

The design of a putkilämmönsiirrin can vary significantly based on its intended application. Common configurations include single-pass, where fluids flow in one direction, and multi-pass, where fluids are directed back and forth multiple times to increase the surface area for heat transfer. The materials used for the tubes and shell are chosen based on the properties of the fluids being handled, such as temperature, pressure, and corrosiveness. Stainless steel, copper, and titanium are frequently employed.

Putkilämmönsiirtimet are widely used across various industries. They are found in HVAC systems for heating and cooling buildings, in power plants for generating electricity, in chemical processing for controlling reaction temperatures, and in refrigeration systems. Their robust construction and ability to handle high pressures and temperatures make them a reliable choice for demanding industrial environments. Maintenance typically involves cleaning the tubes and shell to remove any fouling that could impede heat transfer efficiency.
