Heat conduction device

Japanese Patent JP6340641

B2

PROBLEM TO BE SOLVED: To provide a heat conduction device which can achieve a reduction in weight of a graphene sheet without impairing heat conductivity in an in-plane direction.SOLUTION: A heat conduction device 1 comprises: a heating member 2 which generates heat by energy supplied thereto; a heat dissipation member 3 which dissipates the heat of the heating member 2 to the outside; and a graphene sheet 10 which is a heat-conducting member connecting between the heating member 2 and the heat dissipation member 3 so as to enable heat-conduction therebetween. The graphene sheet 10 comprises: a heat-absorbing part 13 directly or indirectly brought into contact with the heating member 2 in a thickness direction of the graphene sheet 10; and a heat-conducting part 14 extending from the heat-absorbing part 13, and having a leading end directly or indirectly brought into contact with the heat dissipation member 3. The heat-conducting part 14 is formed in a substantially sheet-like shape having a predetermined thickness. The heat-absorbing part 13 has a plurality of faces substantially opposed to the heating member 2 in the thickness direction. The heat-absorbing part is folded in a three-dimensional shape having a length equal to or larger than a thickness of the heat-conducting part 14 in the thickness direction.SELECTED DRAWING: Figure 1
