Abstract

A housing structure for an axial-blowing heat-dissipating fan comprises an annular wall, a plurality of longitudinal slots and at least two combination surfaces. The annular wall forms an air inlet and an air outlet between which to accommodate a fan motor. The longitudinal slots are arranged parallel along an axis of the annular wall on which each of the combination surfaces provided. When the fan motor is rotated, air may synchronously enter the air inlet and the longitudinal slots for increasing inlet air and reducing air noise and then exhaust from the air outlet. The combination surfaces of the two adjacent housing permit an assembled relationship therebetween and alternatively mount to a proper position.

Description

1259241 V. EMBODIMENT OF THE INVENTION u) Technical Field of the Invention The present invention relates to a housing structure of an axial flow cooling fan, and more particularly to forming a plurality of axial slots and at least two combined surfaces for a ring wall to increase heat dissipation The housing of the fan and the stability of the assembly. [Prior Art] A conventional axial flow type cooling fan structure, such as the invention patent of "Blower and Method f〇r Molding Housing Thereof", which is disclosed in U.S. Patent No. 6,132,171. The housing of the cooling fan comprises a ring wall, a substrate and a rotor. The ring wall is round and located on the wind side of the housing. The substrate is rectangular in shape and positioned on the wind side of the housing. The rotor is provided with a plurality of blades and is accommodated in the ring wall. The ring wall is formed by axially stacking a plurality of ring plates, and a plurality of narrow radial slots are formed between the two adjacent ring plates. When the rotor rotates, the blades of the rotor can be sucked into the airflow around the housing via the radial slots to increase the overall intake air. The outer circumference of the annular wall forms four flat cut surfaces, and the flat cut surfaces should be combined. The central portion of the upper, lower, left, and right sides of the panel is substantially in the same plane as the sides of the panel. Since the flat cut surface is still composed of the ring plate and the radial notch, the flat cut surface is formed by supporting a partition outwardly to form a support. The housing may have to be selected for in parallel connection when it is assembled in a personal computer housing for heat dissipation, for example. At this time, the flat sides of the two adjacent casings can be used for corresponding contact bonding. However, since the flat section has a plurality of radial slots, after the assembly of the housing is assembled, the radial slots corresponding to the adjacent flat sections will be opposite each other.

1259241 V. INSTRUCTIONS (2) The respective side suction movements, in addition, because the flat section is convexly connected in parallel, the adjacent two heat-dissipating fans are familiar with the corresponding contact knots, and another conventional axial-flow heat dissipation number "heat dissipation fan" The seat structure Heat~Dissipation Fan is thus tilted. The fan structure [Hous is turbulent, turbulent and turbulent. The block is used, so the use of the flat face block will cause the adjacent two flats. The cut surface, such as the U.S. Patent No. 6,7 1 ing Structure for invention patent, the heat sink fan 0, 486 a shell also includes a ring wall, a composite plate and a rotor. The ring wall is further selected to form a narrow length. However, the housing inlet is not stable enough to be constructed. Therefore, in view of the formation of a plurality of arrangements, the present invention can improve the number of axial slots in the invention. The axial flow to the inconsistent ring wall lacks any parallel connection and it is necessary to enter the same. This creation changes the axial slot to the second and the surface, so as to increase the stability of the assembly. The main purpose is to increase the airflow to the air inlet of the rotor when the rotor is rotated. When the rotor is rotated, the airflow of the rotor flows to the same airflow. Relatively for the purpose of reducing noise. However, under the premise of the construction, the use of the shell is limited to improve the range of the conventional heat-dissipating fan. The one of the above-mentioned shortcomings in a shell is better than the shell. The seat ring wall smoothly draws in the lateral airflow, and the ring wall can be combined or fixed in parallel to fix the housing. The overall air intake and noise reduction, and the accuracy and convenience. For two kinds of axial cooling fans a housing structure having at least two combined faces and a plurality of axial grooves formed thereon

The heat dissipation wind can be at least two walls. The fan can be used to increase the seat utilization. The device fixes the housing and can also smooth the invention to improve assembly stability and air volume. The effect of reducing the blast noise is the structure of the housing of the axial flow cooling fan, and the adjacent positions of the at least two combined faces and the plurality of axial grooves further form a lateral expansion efficiency, so that the invention has a fan a housing structure comprising a ring combination surface, the ring wall forming an air inlet to accommodate a fan motor. The axial slot combination surface is formed on the ring wall. When the air inlet and the axial slot are simultaneously sucked The amount of intake air is reduced and the noise volume is reduced. The combined surface of the group is combined to form a stable white ridge and the combined surface is fixed at an appropriate position. The other objects, features, and advantages of the present invention will be more clearly described and matched. The axial flow heat dissipation system of the first embodiment of the present invention comprises a ring wall 1 〇 forming a main body of a casing 1, and the two ends thereof respectively form an air inlet 1 〇 1 and an out r 1 〇 2 There are several ribs 3 and a pedestal
