Document Type and Number:
WIPO Patent Application WO/2021/106444
Kind Code:
A1
Abstract:
[Problem] To provide: a heat conductive member that can be adapted to various forms of heat sources, has excellent heat dissipation efficiency, and can have reduced heat conduction to adjoining heat sources; and a battery provided with the heat conductive member. [Solution] The present invention pertains to a heat conductive member 1 in which: a plurality of elongated members 10 are arranged and fixed in a width direction perpendicular to a longitudinal direction of the elongated members 10; the elongated members 10 each have a heat conductive sheet 11 as an outer shell; a space 15 is provided inside the outer shell; a surface of the elongated member 10 as viewed in the longitudinal direction thereof is in the shape of an oval, a quadrangle, or a polygon having five or more corners; the plurality of elongated members 10 are arranged such that flat surfaces, or surfaces closest to flat surfaces, of the elongated member 10 are parallel with the width direction; and the plurality of elongated members 10 are fixed on at least opposite end sides in the longitudinal direction thereof by fixing sheets 21 and 22 extending in the width direction. The present invention also pertains to a battery 50 provided with the heat conductive member 1.
