Kelalämmitin

Kelalämmitin is a Finnish term that translates to "fin heater" or "fin radiator." It refers to a type of heating element that is characterized by its finned structure. These fins significantly increase the surface area of the heating element. This increased surface area allows for more efficient heat transfer to the surrounding air, leading to faster and more effective heating.

Kelalämmittimet are commonly used in various applications where rapid and efficient heating is desired. They are frequently found in industrial settings, such as in ovens, dryers, and air curtains. In some domestic appliances, like certain types of space heaters or portable hair dryers, kelalämmittimet can also be employed. The design of a kelalämmitin typically involves a resistive wire or element that is wound around or passes through a series of metal fins. As the resistive element heats up due to electrical current, it transfers its thermal energy to the fins, which then dissipate this heat into the environment. The materials used for the fins are usually good thermal conductors, like aluminum or copper, to maximize heat transfer efficiency. The specific shape and spacing of the fins can be optimized depending on the intended application and the required heating performance.
