  • Flattened heat pipe and manufacturing method thereof
    Patent number: 10408547
    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.
    Type: Grant
    Filed: October 9, 2015
    Date of Patent: September 10, 2019
    Assignee: FURUKAWA ELECTRIC CO., LTD.

  • Heat exchanger tube and method for manufacturing the same
    Patent number: 5992512
    Abstract: A heat exchanger tube for effecting a heat exchange between a fluid inside the heat exchanger tube and another fluid flowing outside the heat exchanger tube, which is provided with a first kind of spiral grooves and a second kind of spiral grooves, each being formed on an outer surface of the heat exchanger tube. The twisting direction of the first kind of spiral grooves in relative to the axis of the heat exchanger tube is the same as that of the second kind of spiral grooves but differs in helix angle from each other with helix angles of the first kind of spiral grooves and the second kind of spiral grooves falling within the range of 3.degree. to 80.degree. in relative to the axis of the heat exchanger tube.
