Résumé

The concept of the network heat pipe employing the boiling heat-transfer mechanism in a narrow space is described. Two flat-plate wickless network heat-pipes (or thermal spreaders) are designed, fabricated, and tested based on this concept. The fabricated thermal spreaders, which are made of copper or aluminium, are wickless, cross-grooved heat transfer devices that spread a concentrated heat source to a much larger surface area. As a result, the high heat flux generated in the concentrated heat source may be dissipated through a finned surface by air cooling. The maximum heat fluxes achieved are about 40 W/cm² for water with a total heat input of 393 W.
