Abstract
Official abstract text for this publication.
An immersion heat dissipation structure is provided. The immersion heat dissipation structure includes a porous metal heat dissipation material, an integrated heat spreader, and a thermal interface material. The porous metal heat dissipation material has a porosity greater than 8%. The porous metal heat dissipation material and the integrated heat spreader have the thermal interface material arranged therebetween so that a thermal connection is formed therebetween. A super-wetting layer is formed on a connection surface between the porous metal heat dissipation material and the thermal interface material, and the super-wetting layer has a wetting angle of less than 10 degrees to water. Alternatively, a super-hydrophobic layer is formed on the connection surface between the porous metal heat dissipation material and the thermal interface material, and the super-hydrophobic layer has a wetting angle of greater than 120 degrees to water.
