jäähdytyskennoon

Jäähdytyskenno, often translated as cooling fin or heat sink, is a passive heat exchanger component designed to increase the surface area of a device for more efficient heat dissipation. It is typically made from materials with high thermal conductivity, such as aluminum or copper. The primary function of a jäähdytyskenno is to draw heat away from a hot component and transfer it to the surrounding environment, usually air or a liquid.

These components are essential in a wide range of applications where heat generation is a concern. In electronics, they are commonly found attached to microprocessors, power transistors, and other heat-generating integrated circuits to prevent overheating and ensure reliable operation. The fins are shaped to maximize the surface area exposed to the cooling medium, allowing for greater heat transfer through convection.

In automotive systems, jäähdytyskenno, often in the form of a radiator, is used to cool engine coolant, transferring heat from the engine to the air. Other applications include cooling in power supplies, lighting systems, and industrial machinery. The design of a jäähdytyskenno can vary significantly depending on the specific application and the amount of heat that needs to be dissipated, ranging from simple extruded fins to complex stamped or bonded structures.
