Abstract: A fan structure automatically mountable on a system circuit board includes a fan. The fan includes a fan frame main body. A connector connection section is disposed on the fan frame main body for connecting with a fan end connector, whereby the fan end connector can be assembled with the fan frame main body. Accordingly, when the fan is mounted on the system circuit board, the fan end connector can be directly pressed down by means of an automated device to plug into the circuit board end connector. Therefore, the manufacturing process can be automated.

Abstract: A fan flow guide structure includes a centrifugal fan impeller and a case. The case includes an upper cover and a base seat. A fan impeller space and a flow passage are defined between the upper cover and the base seat. The fan impeller space serves to receive the centrifugal fan impeller. The flow passage is in communication with the fan impeller space and a lateral wind outlet. A tongue section is disposed in the flow passage in adjacency to the lateral wind outlet. A wind supplementing section is defined opposite to the tongue section. An intake gill section is disposed on the upper cover and/or the base seat in communication with the wind supplementing section. Accordingly, the airflow outside the case can be guided from the intake gill section into the wind supplementing section to enhance the flow amount of the fan.

Abstract: An axial fan frame with electrical connection structure includes a frame and a circuit board. The frame includes a shaft holder having a receiving recess located near an air outlet of the frame for receiving the circuit board therein, a plurality of stator blades connected to between the shaft holder and the frame, a groove formed on an outer surface of the frame for receiving an external cord assembly therein, and a communicating passage located between the receiving recess of the shaft holder and the groove of the frame to communicate them with each other. The circuit board has an outward extended arm, which has a metal contact end for connecting to an electrical connector provided at an end of the external cord assembly. Therefore, the external cord assembly can be quickly electrically connected to the circuit board in an automated manner without the need of welding manually.

CPC classification number: F04D29/281 , F04D29/441
Abstract: A centrifugal-to-axial mixed flow blower includes a blower enclosure defining a blower chamber and a centrifugal impeller supported on an impeller seat to suspend in the blower chamber. The centrifugal impeller includes a plurality of blades and a radially outward declined flow passage defined between any two adjacent blades and communicable with the blower chamber. The blower chamber is communicable with a rectangular air outlet of a heat dissipation system via a frame passage of a flow guide frame connected to below the blower enclosure. Air stream centrifugally drawn in by the centrifugal impeller passes through the declined flow passages to radially outward and downward flow into the blower chamber and then passes through the frame passage to flow axially through the rectangular air outlet into the heat dissipation system, so as to realize the effects of reduced noise, changing centrifugal vortical flow into axial flow, and decreased flow loss.

Abstract: A fluid pressurizing structure and fan using same are disclosed. The fluid pressurizing structure includes a hub having a plate portion located therearound. The plate portion has a first and a second surface provided with a plurality of first and second hollow protrusions, respectively. Each of the first hollow protrusions has a first fluid inlet and a first fluid outlet, and each of the second hollow protrusions has a second fluid inlet and a second fluid outlet. The first and second fluid outlets extend through the plate portion to communicate the first and second fluid inlets with the second and first surface, respectively. When the fan rotates, fluid drawn thereinto sequentially flows through the first fluid inlets and outlets and the second fluid inlets and outlets in a helical movement in cycles, and is therefore continuously pressurized, which facilitates reduced fan vibration and noise and fan motor power consumption.

Abstract: A centrifugal fan frame body structure includes a lower case body and a cover body. The lower case body has a bottom section and an outer wall section. The outer wall section is formed with a wind outlet. The cover body and the lower case body are correspondingly mated with each other to form a space. In the space, the lower case body and the cover body define therebetween a first height. The lower case body and the cover body define therebetween a second height at the wind outlet. The second height is larger than the first height. The height of the wind outlet is enlarged, whereby the wind outlet will not be blocked by the cooperative heat dissipation component (module) so that the flow field efficiency is enhanced and the noise is lowered.

Abstract: A blade wheel structure for axial fan includes a hub and a plurality of blades circumferentially outward extended from the hub. Each of the blades has a tip portion, which is located at a windward side of the blade and is curved in shape. With the curved tip portions of the blades, it is able to create largely increased air pressure and reduce the noise produced during fan operation.
