kuoriputkilämpösiirrin

A kuoriputkilämpösiirrin, also known as a shell and tube heat exchanger, is a common type of heat exchanger used in various industrial applications. It consists of a bundle of tubes enclosed within a larger cylindrical shell. One fluid flows through the tubes, while another fluid flows around the outside of the tubes within the shell. Heat is transferred between the two fluids through the tube walls.

The design of a kuoriputkilämpösiirrin allows for efficient heat transfer due to the large surface area provided by the tubes. The fluids can be configured to flow in either a counter-current or co-current direction. Counter-current flow, where the fluids flow in opposite directions, is generally more efficient as it maintains a larger temperature difference across the heat exchanger, leading to better heat transfer.

Shell and tube heat exchangers are versatile and can handle a wide range of operating pressures and temperatures. They are commonly used in chemical processing, petroleum refining, power generation, and HVAC systems. The materials used for construction depend on the specific application and the properties of the fluids being handled, with common materials including various metals like steel, stainless steel, and copper alloys. Maintenance typically involves cleaning the tubes and shell to remove any fouling or scaling that can impede heat transfer efficiency.
