摘要：A sheet-like heat pipe for a heat-generating element, which is intended to make an electronic device more compact, more lightweight, and thinner, while also reducing costs, is provided. A sheet-like heat pipe (10) of the present invention includes a container (17) in which the peripheries of the sheet-like members (11, 12) disposed facing each other are bonded to form a cavity inside, and a working liquid which is enclosed in a cavity (15) of the container (17). At least one of the sheet-like members (11, 12) disposed facing each other is formed with protruding pieces (12A, 12B) which project outwards from the bonded part with the other sheet-like member and have a spring structure which causes the container (17) to elastically abut a heat-generating element (5) of an electronic device.
主权项：1. A sheet-like heat pipe, comprising: a container in which peripheries of sheet-like members disposed facing each other are bonded at a bonded part to form a cavity inside; and a working liquid which is enclosed in the cavity of the container, wherein at least one of the sheet-like members disposed facing each other is formed with protruding pieces which project outwards from the bonded part with the other sheet-like member and include a spring structure which causes the container to elastically abut a heat-generating element of an electronic device, so that the container directly contacts an entire surface of one side of the heat-generating element without the spring structure and the protruding pieces directly contacting the heat-generating element, the protruding pieces including the spring structure are formed at several locations so as to generate load in different directions on a periphery of the container which abuts the heat-generating element, and the at least one of the sheet-like members and the protruding pieces including the spring structure together form a single integral piece, the protruding pieces project outwards from the container in a direction of extension of the container, and the protruding pieces are abutted against and held at latching parts formed in the electronic device so that the container closely contacts, by a restoring force of the spring structure of the protruding pieces, the heat-generating element with a predetermined elastic force, and so that the container dissipates heat from the heat-generating element.
