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 fan impeller structure includes a hub and a blade set. The hub has a top wall and a circumferential wall extending from a circumference of the top wall. The blade set has multiple upper blades and multiple lower blades. The upper and lower blades are alternately arranged on the circumferential wall. Each upper and lower blade respectively has a first windward face and a second windward face which is extending in a different direction from the first windward face. The first windward face is disposed in such a direction as to face the rear edge of the lower blade on the lower side, while the second windward face is disposed in such a direction as to face the rear edge of the upper blade on the upper side.

Abstract: A fan connector structure is applicable to a system circuit board having a circuit board-end connector provided thereon and includes a fan having a fan frame main body and a fan-end connector projected from an outer side of the fan frame main body. The fan-end connector and the fan frame main body can be selectively integrally or non-integrally formed with each other. The fan-end connector is correspondingly connectable to the circuit board-end connector, so as to realize the purpose of automated and quick assembling of the fan to the system circuit board with less labor and time cost.

Abstract: An anti-press fan structure includes a fan frame and a fan impeller. The fan impeller has a support shaft supporting the fan impeller disposed in the fan frame. The support shaft has a protrusion section protruding from the fan frame to bear and connect with an external unit positioned above the fan impeller so as to keep an axial space between the fan impeller and the external unit. Accordingly, the fan impeller is prevented from being compressed by the external unit and the pressure applied to the fan frame is dispersed.
