Furukawa Review No.27

Trends in State-of-the-Art Heatsinks and Their Patent Technology

Takeshi Hirasawa and Yoshikatsu Inagaki

Abstract

In recent years, the performance of electronic equipment improves year by year, while the equipment continues downsizing. As a result, there is a need for more efficient dissipation of heat generated by the electronic devices incorporated in the equipment. Heatsink plays an important role for such performance improvements, making it indispensable to use high-performance heatsinks suitable for each equipment so as to realize the design and performance required by customers. Accordingly, every heatsink manufacturer earnestly develops various heatsink technologies, thereby improving heatsinks through application of these technologies.
This paper presents technologies for heatsink performance upgrading placing emphasis on the patents owned by Furukawa Electric, together with explanatory description of the trends in state-of-the-art heatsink technologies.
