A heat exchanger tube includes a curved wall, a leg, and a joint. The leg extends orthogonal to an end of the curved wall. The joint connects the curved wall and leg. A plurality of dimples is aligned along the joint.

A heat pipe operating noiselessly by preventing, or reducing the effects of, the mixing of working fluid at different temperatures includes a hollow tube, a capillary structure, a working fluid, and a bushing. The porous capillary structure able to carry the fluid is disposed on an inner wall of the tube. The bushing is hollow, and the bushing is disposed on a surface of the capillary structure away from the tube. The heat pipe is divided into evaporation, adiabatic, and condensation sections, the capillary structure being at all sections. The working fluid is disposed in the capillary structure of the evaporation section, the bushing is disposed on a side of the capillary structure of the adiabatic section.

A process for winding a convolutely wound tubular structure having a machine direction, a cross-machine direction coplanar thereto, and a Z-direction orthogonal to both the machine- and cross-machine directions is disclosed.

An integrated vapor chamber includes an outer shell and a plurality of composite capillary structures. The outer shell includes a flat casing and a plurality of partitions integrally formed. The flat shell includes a chamber, and the partitions are disposed in the chamber to separate the chamber into a plurality of flow channels. Each composite capillary structure is extended along each flow channel and distributed in the chamber. The composite capillary structure includes a metal mesh and a plurality of sintered powder uniformly sintered in the metal mesh. Furthermore, this disclosure also discloses a manufacturing method of the integrated vapor chamber. Therefore, the manufacturing method of the thin vapor chamber is simplified to improve the yield rate.

A method includes: an inner pipe insertion step of inserting an inner pipe to between a cored bar and a metal movable claw; a designated section corrugated portion formation step of forming a corrugated portion in a first designated section by pressing the first designated section of the inner pipe radially inward by the metal movable claw and plastically deforming the first designated section; a movable claw moving step of moving the metal movable claw outward in the radial direction of the inner pipe; and an inner pipe moving step of moving a second designated section that is the next designated section to between the cored bar and the metal movable claw.

A sticker for spacing wood is extruded from an aluminum alloy. The sticker can have different configurations. In a first configuration, the sticker has a width about the same as its height, with longitudinal ridges on all sides that grip wood when wood is stacked on the sticker. In a second configuration, the sticker has a width significantly greater than its height, with longitudinal ridges on the top and bottom surfaces, and with smooth side surfaces. The longitudinal ridges have a height within a specified range and are spaced at a distance peak-to-peak within a specified range. The ridges provide good grip of lumber stacked on the sticker yet do not easily plug with wood fibers through repeated use. The extruded aluminum sticker is very rugged and can be used for hundreds or even thousands of drying cycles.

The present invention is related to a thin heat dissipation device and a method for manufacturing the same. The device of the present invention mainly comprises a hollow body having an enclosed chamber and a working fluid with which the enclosed chamber is filled. The enclosed chamber comprises a first fluid channel and a second fluid channel. The first and second fluid channels extend in the longitudinal direction of the hollow body, are juxtaposed in the width direction of the hollow body and communicated with each other, and an interface between the first fluid channel and the second fluid channel has a height of about 0.1 mm or less. As such, a novel capillary structure which is capable of greatly reducing the entire thickness, enhancing heat transfer efficiency and reducing cost and which is reliable and durable is provided.

A method for calibrating a metal profile blank configured as a hollow-chamber profile having at least one solid wall. A pressing tool is closed in a main direction about one end region of an element of the profile blank until surfaces of the pressing tool lie against a pair of surfaces of the profile blank to be calibrated, deforming and bending the at least one end region of the element. The pressing tool is closed in a secondary direction perpendicular to the main direction until surfaces of the pressing tool lie against surfaces of the at least one end region, and wedge-like limbs of a drive element of the pressing tool engage wedge-like dies of the pressing tool. The pressing tool is closed further in the secondary direction, subjecting the profile blank to plastic deformation so as to reduce or eliminate the bending of the end region.

A vehicle structural member includes an elongate hollow member having an integrated structure, and supporting members joined to the elongate hollow member. The elongate hollow member includes: a first portion that includes a first pipe, a second pipe disposed outside the first pipe and extending along the first pipe, and a connection portion extending along the first pipe and the second pipe, formed integrally with the first pipe and the second pipe, and connecting the first pipe and the second pipe; and a second portion that includes the first pipe continuing from the first portion, and does not include the second pipe.

A heat exchanger tube includes a curved wall, a leg, and a joint. The leg extends orthogonal to an end of the curved wall. The joint connects the curved wall and leg. A plurality of dimples is aligned along the joint.
