Levylämpövaihtimia

Levylämpövaihdin is a Finnish term referring to a plate heat exchanger. It is a type of heat exchanger that uses metal plates to transfer heat between two fluids. These fluids can be liquids or gases. The plates are typically made of stainless steel and are corrugated to increase the surface area for heat transfer and to provide structural support.

The fluids flow through alternating channels between the plates. One fluid flows through one set of channels, and the other fluid flows through the adjacent set. Heat is transferred from the hotter fluid to the colder fluid through the thin metal plates. The corrugated design of the plates also induces turbulence in the fluid flow, which further enhances the efficiency of heat transfer.

Levylämpövaihtimia are widely used in various applications due to their compact size, high thermal efficiency, and ease of maintenance. They are commonly found in industrial processes, HVAC systems, refrigeration, food and beverage production, and power generation. Their modular design allows for easy adjustment of the heat transfer capacity by adding or removing plates. Maintenance typically involves cleaning the plates to remove any fouling or scaling that can reduce performance.
