    Abstract: A fan includes a motor base, a bearing, an impeller, a stator and a magnetic element. The motor base has a bearing stand in a center portion thereof. The impeller includes a metallic case, plural blades and a rotating shaft. A top surface of a top wall of the metallic case continuous with curved surface that defines part of a central opening, and a depth of the central opening is equal to a thickness of the top wall. The blades are disposed around an outer periphery of said metallic case. The rotating shaft is inserted into the central opening and penetrated through the bearing stand, wherein no raised ring structure is formed in the top wall, and the rotating shaft and the metallic case are jointed together by a laser welding process. The magnetic element is disposed on an inner wall of the metallic case and aligned with the stator.

    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 heat pipe comprises a first pipe and at least a second pipe. The first pipe includes an evaporator, a heat insulator and a condenser communicating with each other to define a hollow chamber. The second pipe disposed in the hollow chamber includes an accommodating space and a first capillary structure disposed in one end of the accommodating space closer to the evaporator. At least one side of an outer pipe wall of the second pipe directly abuts an inner pipe wall of the first pipe. The first pipe further includes a second capillary structure disposed in the hollow chamber closer to the evaporator and extended to an outside of the second pipe and occupies at least 2/3 volume of the evaporator. A first part of the first capillary structure and the second capillary structure are connected to each other by winding so as to enhance transportation therebetween.

    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.
