Radiating fan casing seat

Abstract

The invention provides a radiating fan casing seat, comprising an outer frame, a bearing part and a plurality of fixed blades, wherein, the outer frame is internally equipped with a holding space; an air inlet and an air outlet are respectively formed at two ends of the holding space; the bearing part is arranged in the holding space; and the fixed blades are combined between the outer frame and the bearing part. The holding space of the outer frame sequentially forms a moving blade area, a fixed blade area and a current collecting area from the air inlet towards the air outlet, wherein, the fixed blades are positioned in the fixed blade area; the fixed blades are respectively provided with a first end edge towards the air inlet and a second end edge towards the air outlet; and the current collecting area is positioned between the second end edge and the air outlet. In the invention, the current collecting area can be effectively adopted to concentrate and guide air current so as to achieve the efficacies of reduced noise, increased wind pressure, saved power consumption and the like.

Description

technical field [0001] The present invention relates to a fan frame structure, in particular to a heat dissipation fan case seat with stator vane design. Background technique [0002] At present, the common heat dissipation fan housings on the market usually have a vane structure, so that the design of the vane can be used to achieve the effect of pressurization and flow diversion. Such as China Taiwan Announcement No. 488497 "fan pressurization deflector device" new patent, discloses the first kind of existing cooling fan case seat with stationary blade. Please refer to figure 1 As shown, the heat dissipation fan case seat 80 has an outer frame 81, and the inner side of the outer frame 81 has a receiving portion 82, and the receiving portion 82 can be combined with a moving blade 83, and the rotating blade 83 is controlled by a driving device 85. , and the bearing part 82 is connected with a flow guiding device composed of several stationary vanes 84, and each of the stat...

Problems solved by technology

[0006] However, although the second type of existing heat dissipation fan case base 90 utilizes the wing-shaped air guides 93 to achieve the function of reducing noise, it must also form several airfoil guides on the inner edge of the outer frame 91. Part 93, so it is not easy to make and shape, and relatively leads to an increase in the overall manufacturing cost

Furthermore, although the bottom edge 931 of each wing-shaped air guide 93 of the existing cooling fan case base 90 is not aligned with the air outlet 912 of the outer frame 91, the bottom edge 921 of each stationary vane 92 is still It is aligned with the air outlet 912 of the outer frame 91; therefore, the inner side of the outer frame 91 near the air outlet 912 has no structural design for concentrating the air flow; when the rotor blade 94 rotates, the air flow generated If it is not concentrated, it will cause the airflow to spread to different directions immediately after passing through each of the stator blades 92, and also cause the airflow to easily generate wind shear noise between each other, and still affect each of the stator blades 92 is used to strengthen the effect of the wind pressure of this airflow
