Top 10 heat sink Manufacturers in the world 2025

Introduction to Heat Sinks

A heat sink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature. Heat sinks are essential components in various industries, including electronics, automotive, and power generation. They play a crucial role in ensuring the proper functioning and longevity of devices by preventing overheating.
