As liquid cooling technology is more readily adopted in electronics thermal management, particularly where very high heat fluxes are involved, there is a push to develop more efficient and cost effective cold plates to transfer device heat into the liquid cooling loop.  More than twenty years ago, Tuckerman and Pease pioneered the notion of microchannels for high-capacity cooling. They noted that one particularly effective design would be to carve microscale channels into a piece of material.  The local heat transfer coefficient increases with the decrease of channel size and heat transfer would increase as more surface area is generate.
How do you create a cost effective and thermally efficient microchannel heat sink from this?  Click to ATS’s free “how to do it” paper by ATS’s Thermal Team, by visiting this link, “Using Silicon Microchannel Heat Sinks for Thermal Management“
