Abstract: A heat pipe including a container being a tubular body, the container having an end surface of one end portion and an end surface of another end portion, the end surfaces each being sealed; a wick structure provided inside the container; and a working fluid enclosed inside the container. The wick structure includes a first wick portion and a second wick portion in at least one cross section perpendicular to a longitudinal direction of the container, the second wick portion being integral with the first wick portion, the second wick portion extending outward from the first wick portion, the second wick portion being thinner than the first wick portion, and the second wick portion includes a flat portion extending in a direction perpendicular to a height direction of the internal space of the container.

Abstract: The invention provides a flattened heat pipe whose vapor flowing passage is not clogged and which has an excellent capillary force. The flattened heat pipe has a closed container formed by flattening a tubular container, a plurality of wick structures arrayed within the container in a longitudinal direction so as to form an acute-angled portion where a capillary force is large at least partially within the container, a hollow portion formed of an outer peripheral surface of the wick structure and an inner wall surface of the container and a working fluid sealed into the container.

Abstract: An object of the present disclosure is to provide a heat sink that can equalize heat input in a heat receiving portion and increase a volume of the heat receiving portion, prevent an increase in heat resistance in the heat receiving portion even when a heat generation amount from a heat-generating element increases, and exhibit excellent cooling performance with respect to a cooling target.There is provided a heat sink including: a heat transport member having a heat receiving portion thermally connected to a heat-generating element; a tube body connected to a heat insulating portion or a heat radiating portion of the heat transport member; and a heat radiation fin group which is thermally connected to the tube body and in which a plurality of heat radiation fins are arranged, in which the heat transport member has an integral internal space that communicates from the heat receiving portion to a connection portion with the tube body and is sealed with a working fluid, and the internal space of the heat transport member communicates with an internal space of the tube body.

Abstract: A heat pipe has a heat receiving portion that is to be thermally connected to a heat generating member so as to absorb heat from the heat generating member. The heat pipe includes a sealed flat container; a wick structure housed inside the flat container; and a working fluid sealed inside the flat container. In at least one cross section of the flat container, the wick structure includes a first wick member and a second wick member disposed vertically, the wick structure also has a first wick part and a second wick part respectively disposed in the lengthwise direction of the flat container, the second wick part having a maximum width that is wider than a maximum width of the first wick part. The second wick part is disposed in the heat receiving portion of the heat pipe.
