Influence of the Fin Shape on Heat Transport in Phase Change Material Heat Sink with Constant Heat Loads

Nowadays, the heat transfer enhancement in electronic cabinets with heat-generating elements can be achieved using phase change materials and finned sink. The latter allows to improve energy transference surface augment cooling effects for sources. present research deals numerical analysis of material behavior an cabinet energy-generating element. For intensification removal, complex sink overall width 10 cm was introduced, having complicated shape fins 0.33 height H = 5 cm. fatty acid melting temperature 46 °C considered as a material. two-dimensional challenge formulated employing non-primitive variables solved finite difference method. Impacts volumetric flux element sizes on circulation within chamber were studied. It shown that presence transverse ribs makes it possible accelerate process reduce source by more than 12 at load 1600 W/m. should also noted nature depends hydrodynamics melt, so horizontal partitions intensity convective between upper part region lower part.
