Title:
HEAT DISSIPATION STRUCTURE AND BATTERY HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2020/105377
Kind Code:
A1
Abstract:
[Problem] To provide: a heat dissipation structure which can conform to various shapes of heat sources, has a light weight, has an abundant elastic deformation property, and has excellent heat dissipation efficiency; and a battery provided with said heat dissipation structure. [Solution] The present invention pertains to a heat dissipation structure 25 in which a plurality of heat dissipation members 28 for enhancing heat dissipation from a heat source 20 are connected, and to a battery 1 provided with the same, wherein the heat dissipation members 28 are each provided with: a heat conductive sheet 30 having a shape that extends while winding in a spiral shape for transferring the heat from the heat source 20; a cushion member 31 which is provided on an annular rear surface of the heat conductive sheet 30 and can be more easily deformed to conform to the outer surface shape of the heat source 20 than the heat conductive sheet 30; and a penetration path 32 penetrating in the direction in which the heat conductive sheet 30 extends while winding, the plurality of heat dissipation members 28 being connected to each other by connection members 35 in a state of being aligned in a direction perpendicular to the direction in which the heat conductive sheet 30 extends while winding.
