Plissékaihtimet

Plissékaihtimet, a term of Finnish origin, describes a specific type of heating device. Literally translating to "pleated chimney" or "folded chimney," it refers to a heating system that utilizes a series of folded or pleated metal sheets to create a larger surface area for heat exchange. This design is intended to maximize the efficiency of heat transfer from the combustion gases to the surrounding air or water.

These heating systems are often found in specialized industrial applications or in certain types of wood-burning stoves and boilers where enhanced heat recovery is a primary concern. The pleated structure allows for a more compact unit while still providing the extensive surface area that a traditional, smooth-surfaced heat exchanger would require. The airflow or water flow is directed across these folded surfaces, facilitating a more thorough absorption of thermal energy before the exhaust gases are released. The specific materials used in plissékaihtimet can vary, but they are typically heat-resistant metals capable of withstanding high temperatures. Their construction requires precise engineering to ensure durability and optimal performance in demanding environments.
