COOLING APPARATUS WITH SURFACE ENHANCEMENT BOILING HEAT TRANSFER

摘要

A cooling apparatus boiling and condensing liquid coolant has a vessel including a microporous surface enhancement coating applied on a thermally-conductive plate which is fully immersed under the liquid coolant in the vessel. The surface enhancement coating augments significantly a nucleate boiling heat transfer and critical heat flux when receiving heat from a heating object coupled to the thermally-conductive plate at a surface outside of the vessel. One embodiment of this invention including a vessel with a height/length dimension less than 300mm, a microporous coating with nickel particles of 30-50µm in size bonded by a thermally-conductive binder, and water as the liquid coolant, without complicated radiator component, is used for cooling a heating electronics element.
