Abstract: A heat pipe comprises a tube and a wick structure. The tube includes a hollow chamber and has two sealed ends along an axial direction. The wick structure is disposed in the hollow chamber and extended along the axial direction of the tube. The wick structure has a first section near one of the sealed ends, a third section near the other of the sealed ends, and a second section between the first and third sections. The wick structure is composed of the first, the second and the third sections, and cross-sections of the first section, the second section and the third section in the axial direction are rectangles, respectively. A cross-sectional area of the first section is greater than that of the second and that of third section. The edge of each of the sections of the wick structure has a smooth form without the sectional difference.

Abstract: A vapor chamber with a support structure and its manufacturing method are provided. The vapor chamber with the support structure includes a first plate, a second plate spaced apart from the first plate, and multiple support elements fixed between the first and second plates. On an outer surface of any of the first plate or the second plate, laser welding is performed on positions corresponding to the support elements so as to join the support elements to the first and second plates and to form weld ports on the outer surface of any of the plates. The invention solves the problem of fixing the support structure inside the thin vapor chamber, and therefore mass production can be realized.

Abstract: A heat pipe is divided into an evaporation section, an insulation section and a condensation section. The insulation section includes a pipe section and a liquid delivery structure. The pipe section has a top wall and a bottom wall. The liquid delivery structure is a solid structure and in contact with the top and bottom walls of the pipe section. The liquid delivery structure and the top and bottom walls of the pipe section form a vapor channel. The liquid delivery structure is divided into a center portion and an outer layer, and the center portion has a porosity greater than the porosity of the outer layer. The outer layer is coupled to the center portion, and the center portion and the vapor channel are spaced from one another, so as to achieve the liquid and vapor isolation and improve the heat conducting effect of the heat pipe.

Abstract: A heat pipe comprises a flat tube and a wick structure. The flat tube includes a hollow chamber and has a front and a rear sealed ends along an axial direction. The wick structure is disposed in the hollow chamber and extended along the axial direction of the flat tube. The wick structure is divided into a front, a middle and a rear sections sequentially along the axial direction. The front section is near the front sealed end, the rear section is near the rear sealed end. The front, middle and rear sections have a maximum length parallel to the width direction, respectively. The maximum length of the front section is greater than that of the middle section, and the maximum length of the middle section is greater than that of the rear section.
