PERFORMANCE OF A MULTI-STACK MICROCHANNEL HEAT SINK

Jurnal Teknologi, 2016
The usage of a very large scale integrated circuits generate high heat fluxes and require an effective cooling system. A microchannel heat sink (MCHS) is one of the reliable cooling systems that had been applied. In terms of performance, a MCHS can be appraised by obtaining low total thermal resistance and pumping power.
