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: The present invention provides a motor structure including a heat dissipation module, a motor base, a circuit board, a rotor and a winding set. The heat dissipation module has a first side and a second side opposite to each other. The motor base is connected to the heat dissipation module. The first side and the second side are uncovered. The thermal conductivity of the heat dissipation module is greater than that of the motor base. The circuit board is disposed on the first side. The rotor is disposed on the second side. The winding set is disposed on the second side and electrically connected to the circuit board to drive the rotor to rotate. By integrating the motor base and the heat dissipation module into one piece, the assembly process is simplified, and the use of components is eliminated. It benefits to achieve the effects of waterproofing, dustproof and protection.

Abstract: A centrifugal fan with dual outlets in the same direction includes a fan frame, an impeller, and a motor. The fan frame includes an upper cover, a base plate and a first air deflector. The base plate and the upper cover are connected to form an accommodating space and an air outlet plane. The first air deflector is arranged near the air outlet plane and divides the air outlet plane into a first air outlet and a second air outlet. The impeller is disposed in the accommodating space. The impeller and the side wall of the fan frame form a flow channel therebetween. The motor is connected to the impeller and drives it to rotate. The first air deflector extends inward of the flow channel from the air outlet plane and the end of the first air deflector has a first guide portion, which is a slanted surface.

Abstract: A fan includes a base, a motor and an impeller, and the motor includes a sleeve, a rotor, a position limiting element and a composite elastic element. The sleeve is disposed on the base, and the sleeve has a bottom portion and a side wall, which constitute an accommodation space. The rotor has a rotating shaft disposed within the accommodation space, and the rotating shaft has an outer wall. An annular groove is formed on the outer wall and has a surface. The position limiting element is disposed on the sleeve and extended from the side wall toward the rotating shaft, and the position limiting element has a bottom surface. The bottom surface faces toward the bottom portion, and the bottom surface is interfered with the surface, thereby eliminating the gap between the bottom surface and the surface. Therefore, noise of the up and down vibration is avoided from generating.
