Abstract: A heat dissipation assembly is disclosed and includes a frame and a fan. The frame includes a heat conduction channel and an airflow intake. The heat conduction channel is communication with an exterior through airflow intake. The frame includes a first plane, a second plane and an inclined plane. The first plane is disposed adjacent to the airflow intake. The inclined plane is connected between the first plane and the second plane. The second plane includes an inlet. The heat conduction channel is in communication between the airflow intake and the inlet. A cross-section area of the heat conduction channel adjacent to the airflow intake is greater than that of the heat conduction channel adjacent to the inlet. The fan is spatially corresponding to the inlet, and assembled with the frame to form an outlet in communication with the airflow intake and the heat conduction channel through the inlet.

Abstract: A fan includes a fan frame and a driving device. The fan frame includes a base, a frame shell and static blades arranged on the periphery of the base. The driving device includes a stator structure and a rotor structure. The stator structure includes a stator magnetic pole group and a bushing. The rotor structure includes a bearing, a shaft, a rotor shell, a magnetic structure and blades. The shaft is connected with the rotor shell and disposed through the bearing. The stator magnetic pole group magnetically drives the magnetic structure to rotate the rotor shell. The blades are arranged on the periphery of the rotor shell. Two ends of the frame shell are configured with two turning portions, respectively. The two turning portions are disposed between parts of the frame shell with different curvatures.

Abstract: The disclosure relates to an asymmetrical double-outlet blower, including an upper case, a lower case and an impeller. The upper case includes an inlet. The lower case and the upper case are assembled to form a housing having an accommodation space, and form a first outlet and a second outlet. The accommodation space is in fluid communication with the first outlet, the second outlet and the inlet. The first outlet and the second outlet are disposed on a lateral periphery of the housing and face two opposite directions, respectively. An opening cross-sectional area of the first outlet is less than an opening cross-sectional area of the second outlet. The impeller is accommodated within the accommodation space of the housing, spatially corresponding to the inlet, and rotated around a rotation axis. An airflow is inhaled through the inlet and transported to the first outlet and the second outlet, respectively.

Abstract: A centrifugal fan is disclosed and includes a lower case, an impeller and an upper case. The lower case includes a bottom plate and a sidewall. The impeller is disposed on the bottom plate. The upper case is assembled with the sidewall to form an outlet. The upper case is formed by stamping and includes a first plane, an inlet and a grille. When the impeller is rotated, an airflow flowing from the inlet to the outlet is formed. The grille is protruded outwardly from the first plane, and includes a connecting frame and plural ribs. A spacing height is formed between the connecting frame and the inlet. Each rib has a first end connected to the connecting frame and a second end connected to the first plane. A pair of notches are disposed adjacent to two opposite lateral edges of the second end of the corresponding rib, respectively.

Abstract: An impeller includes a hub and blades. In radial direction, an upper surface of the blade near the outer edge includes a groove structure, a lower surface of the blade relating to the groove structure includes a peak structure, the lower surface of the blade includes a recess structure aside the trailing edge or the leading edge. The recess structure is connected to the peak structure. The blade has at least five airfoils from the inner edge to the outer edge. The blade is defined by continuously connecting the at least five airfoils at different sections in sequence so as to form the groove structure and the peak structure respectively on the upper surface and the lower surface. The groove structure and the peak structure are aside the outer edge of the blade.
