HEAT TRANSPORT DEVICE, ELECTRONIC APPARATUS AND METHOD OF MANUFACTURING THE HEAT TRANSPORT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a heat transport device capable of efficiently performing heat transport, an electronic apparatus including the heat transport device and a highly reliable method of manufacturing the heat transport device facilitating manufacturing.

SOLUTION: A heat spreader 1 includes a container 2 constituted of a heat receiving plate 4, a heat radiation plate 3 provided opposing to the heat receiving plate 4, and side walls 5 for airtightly jointing the heat receiving plate 4 and the heat radiation plate 3 to each other. A refrigerant is filled in the container 2. An evaporation portion 7 is provided on an evaporation face 42 of the heat receiving plate 4 constituting the inner wall face of the container 2. The evaporation portion 7 includes: grooves 71 in which a liquid-phase refrigerant can be moved; and protrusion portions 75 made of a nanomaterial protruded from inner wall faces 72 of the grooves 71 so as to partially cover opening faces of the grooves 71. The liquid-phase refrigerant is made to flow in liquid-phase flow passages 74 formed within the grooves 71.
