Lämmönsiirtolaite

Lämmönsiirtolaite, known in English as a heat exchanger, is a device designed to efficiently transfer thermal energy from one medium to another. The two media are typically separated by a solid wall, preventing them from mixing. This separation allows for controlled heating or cooling processes.

Heat exchangers are crucial components in a vast array of applications, from everyday conveniences to industrial operations. In domestic settings, they are found in central heating systems, where they transfer heat from a boiler to the circulating water, and in refrigerators, where they facilitate the removal of heat from the interior. Air conditioning units also rely heavily on heat exchangers to cool indoor air.

Industrially, heat exchangers are indispensable. They are used in power plants to generate steam, in chemical processing to control reaction temperatures, and in manufacturing to manage heat in various stages of production. The design of a heat exchanger varies significantly depending on its intended use, including factors like the types of fluids involved, the required heat transfer rate, and operating pressures and temperatures. Common types include shell and tube, plate, and finned tube heat exchangers. The efficiency of a heat exchanger is a key performance indicator, influencing energy consumption and operational costs.
