Experimental And Numerical Study Of Aluminium Microchannel Heatsink
Main Article Content
Abstract
Metallic micro channels are attractive option for electronics cooling applications. In this paper experimental and numerical study of aluminium based micro channel heat sink is studied. Rectangular micro channel of 400μm width and 800μm depth is machined on circular aluminium blank using micro milling technique. The thermal and fluid flow characteristics is found experimentally and validated with CFD software using FloEFD for three flow rates 5.26g/s, 7.7g/s, and 9.43g/s. The pressure drop is measured to vary from 1558Pa to 3432Pa. The maximum performance index of 45 is found 45. The simulated results have been validated with the experimental results. Variation of Nusselts number and heat transfer coefficient with respect to flow rate also discussed.
