Abstract

The paper contains charts of the micro-channel structures´ simulation data from a benchmark done using air as a cooling medium. It is showing Rth and other performance data in comparison to needed air volume in m³/h. Therefore, several Rogers’ standard micro-channel-structures, such as Qua 50, 100, Hex 50 and off the shelf standard lamellar heat sinks were benchmarked in thermal simulations using Solid Works. Comparing the results at a given flow rate of 1 m³/h all Rogers’ cooling structures show a lower chip temperature then the reference coolers. This is due to a higher heat transfer coefficient of these cooling structures resulting in up to 43 % lower thermal resistances versus the benchmark. Summing up the results show a clear picture, for certain use cases Rogers’ micro-channel coolers can close a gap for customers using air cooling but reach the limits of current solutions and future needs
