Levylämmönsiirrim

Levylämmönsiirrin is a Finnish term that translates to "plate heat exchanger" in English. It is a type of heat exchanger that uses metal plates to transfer heat between two fluids. These fluids can be liquids or gases, and they flow in separate channels created by the plates. The design of a plate heat exchanger allows for efficient heat transfer due to the large surface area provided by the plates and the thinness of the plates themselves.

The construction of a levylämmönsiirrin typically involves a series of thin, corrugated metal plates stacked together. Gaskets are used between the plates to prevent leakage and to direct the flow of the fluids into alternating channels. The corrugations on the plates increase turbulence, which enhances heat transfer efficiency. The fluids enter the heat exchanger at opposite ends and flow through their respective channels, with heat being exchanged across the plate material.

Levylämmönsiirrim are widely used in various industrial applications due to their compactness, high efficiency, and ease of maintenance. They are commonly found in HVAC systems, refrigeration, food processing, chemical industries, and power generation. Their modular design allows for easy adjustment of the heat transfer capacity by adding or removing plates. The materials used for the plates and gaskets are chosen based on the fluids being handled and the operating temperature and pressure.
