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 at optimal levels. Heat sinks are widely used in various industries such as electronics, automotive, aerospace, and telecommunications. In the electronics industry, for example, heat sinks are crucial for components like CPUs, GPUs, and power transistors, as these components generate a significant amount of heat during operation. Without proper heat dissipation, the performance of these components can be severely degraded, and their lifespan can be shortened.
