<p>A method and apparatus of cooling a heat source 120, comprises coupling a fin diffuser 102 to a heat spreader 112 to define a cooling assembly 100, and coupling the cooling assembly to the heat source and spreading heat from the heat source thereby cooling the heat source by using a centrifugal fan 104. The fan is integrated with the fin diffuser. The heat spreader may comprise a vapour chamber (202, fig 2) for spreading the heat using motion of working fluid in the vapour chamber. The working fluid transfers heat via an evaporation condensation cycle. The spreader may comprises a capillary wick heat pipe or an oscillating heat pipe (304, fig 3) that transfers heat away from the heat source a in radial direction. The apparatus may comprise a plurality of heat pipes used to cool a plurality of heat sources. At least one heat pipe may direct heat in a perpendicular direction towards and away from a surface of the spreader (fig 7).</p> |
