    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 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 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 bearing is accommodated within the bearing stand. The impeller includes a metallic case, a hub, plural blades and a rotating shaft. The metallic case has a top wall and a sidewall. The hub is sheathed around the metallic case. The blades are disposed around an outer periphery of the hub. The rotating shaft is inserted into a central opening of the top wall and penetrated through the bearing stand, wherein no raised ring structure is formed in the top wall of the metallic case, 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.
