Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a fan frame structure, and more particularly to a heat dissipation fan housing having a vane design. [Prior Art] The cooling fan housing that is seen on the market usually has a vane structure to achieve the effect of pressurized flow using the vane design. For example, the new patent of the Republic of China Announcement No. 488497 "Fan Pressurized Diversion Device" discloses that the first type has a (4) customary case. As shown in the figure, the heat dissipation fan housing 80 has an outer frame 8 and an inner frame & and a receiving portion 82. The receiving portion 82 can be combined with a moving blade 83. The rotation is controlled by the driving device 85, and the receiving portion is slidably connected to the flow guiding device composed of a plurality of vanes 84. Each of the vanes 84 is radially disposed around the receiving portion 82 for deriving the The moving blade 83 rotates the generated air flow to enhance the wind pressure of the air flow. However, as shown in FIG. 2, the outer frame 81 is further provided with an air inlet m and an air outlet 812. Each of the vanes 84 has a bottom edge 841 adjacent to the air outlet 812. The bottom edge 841 of each of the vanes 84 of the seat 80 is aligned with the air outlet 812 of the outer frame 81, so that the inner side of the outer frame 81 has no structural design capable of collecting airflow near the air outlet 812; therefore, the The airflow generated by the rotation of the buckets 83 is not concentrated. 'When the airflow passes through the vanes 84, it is inclined by the axial direction of each of the vanes 84 relative to the outer frame 81. The airflow is immediately diffused to different directions, so that the airflow is likely to generate wind-cut noise with each other at 201035454, and the effect of each of the vanes 84 to enhance the wind pressure of the airflow is still quite limited. In addition, although the above description is made only by the bottom edge 841 of each of the vanes 84 being aligned with the air outlet 812; however, the heat sink housing 80 may still be limited in various processes during actual manufacturing. Uncertain factors in the process (such as mold tolerance or process control such as quality control), so that the bottom edge 841 of each of the vanes 84 of the partial heat sink housing is not completely aligned with the air outlet 812 (not shown); It should be emphasized here that the bottom edge 841 of each of the vanes 84 is not completely aligned with the air outlet 812 due to process error, but the bottom edge 841 and the air outlet 812 are There is still not enough room to form a structural design that can be used to direct the flow. In addition, as for the invention patent of the Republic of China Certificate No. 1276743 "Fan frame and fan with a guide vane", the second known heat-dissipating fan seat with a stationary blade is disclosed. As shown in FIG. 3, the heat dissipation fan housing 90 has an outer frame 91 for combining a moving blade 94. The outer frame 91 is provided with an air inlet 911 and an air outlet 912, and the inner side of the outer frame 91 is equally spaced. A plurality of vanes 92 are arranged and arranged, and between each of the two vanes 92, a wing-shaped baffle 93 extending from the inner edge of the outer frame 91, each of the vanes 92 and each of the wing guides The flow members 93 respectively have a bottom edge 921, 931 adjacent to the air outlet 912. By the combination of the airfoil guides 93 and the vanes 92, the flow generation is reduced to reduce the airflow. The noise that may be generated by each vane 92. However, the second conventional heat-dissipating fan housing 9 uses the respective wing-shaped deflecting members 93 to achieve the function of reducing noise, but must also form a plurality of wing-shaped guides on the inner edge of the outer frame 91. The flow piece 93, so it is not easy to make the molding on 201035454, and it is difficult to make the increase. Moreover, although the bottom edge 931 of each of the wing-shaped baffles 93 of the conventional heat-dissipating fan housing 90 is not aligned with the air outlet 912 of the outer frame 91, the bottom edge 921 of each of the vanes 92 is still The air outlet 912 is aligned with the outer frame 91. Therefore, the inner side of the outer frame 91 is also designed to have no concentrated airflow near the air outlet 912; when the rotor 94 rotates, If the money has not been concentrated, the airflow will be immediately spread to the unidirectional direction after passing through each of the women's leaves 92, and the airflow will easily generate wind-cut noise between each other' and still affect each of the static S 92帛 to enhance the effect of the wind pressure of the airflow. SUMMARY OF THE INVENTION The present invention provides a heat dissipating fan housing for airflow to pass through the vanes and still substantially cover the towel-off direction, to reduce the noise and increase the wind of the reel housing. Pressure is the main purpose of the invention. In order to achieve the foregoing object, the technical means and the functions that can be achieved by the technical method include: a heat dissipation fan housing comprising an outer frame, a receiving portion and a plurality of vanes, the outer An accommodating space is formed in the frame, and an air inlet and an air outlet are respectively formed at the two ends of the accommodating space. The receiving portion is disposed in the accommodating space, and the stationary blades are coupled to the outer frame and the receiving portion. between. The accommodating space of the outer frame sequentially forms a moving blade area, a stationary leaf area and a collecting area from the air inlet opening toward the air outlet, wherein the stationary leaves are located in the stationary leaf area, and each of the stationary leaves is respectively There is a first end edge facing the air inlet and a second end edge facing the air outlet. The current collecting area is located between the second end edge of each of the vanes and the air outlet of 201035454. Thereby, in order to utilize the concentrated concentrated airflow in the collecting area, the utility model can reduce noise, increase wind pressure and save electricity. The outer frame has an axial height 'the second end edge of each of the vanes has a first axial distance between the air outlets, and the first end edge of each vane has a first end edge to the first end edge a second axial distance; wherein the first axial distance occupies at least twenty percent of the axial height, the second axial distance occupies at least ten percent of the axial height; or, the first The axial distance may also be equal to the second axial distance. Thereby, the bucket area still has enough space for accommodating the body _-blade, so as to further form the current collecting area without the air volume provided by the moving blade, thereby ensuring The airflow concentration effect of the current collecting area. The frame has a horizontal reference plane, and each of the rotating leaves has a windward side facing the air inlet, and the windward surface has an angle between the line connecting the second end edge and the horizontal reference surface, and the refreshing angle is between Sixty to seventy-five degrees. Thereby, the airflow generated by the moving blades can be concentrated and less likely to spread. Said all. The second end edge of the static vane or the second end edge of the partial vane further forms a baffle, and each of the baffles extends toward the choke toward the air outlet of the outer frame. Thereby, each of the baffles can be combined with the current collecting zone to form a better airflow concentration effect. Each of the baffles is perpendicular to the horizontal reference plane of the outer frame. Thereby, the effect of each of the crucibles for preventing the diffusion of the airflow is more remarkable. The above and other objects, features and advantages of the present invention will become more apparent from the following description of the appended claims. Referring to Figures 4 and 5, the heat-dissipating fan housing of the present invention includes at least one outer frame 10, one receiving portion 20 and a plurality of vanes 30. The outer frame has an accommodating space 11 and an air inlet 12 and an air outlet 13 respectively formed at two ends of the accommodating space 11. Further, the accommodating space 11 of the outer frame 1 依 sequentially forms a moving blade region 111, a stationary blade region 112 and a collecting region 113 from the air inlet 12 toward the air outlet 13 . The receiving portion 20 is disposed in the accommodating space u of the outer frame 1 , and is mainly located in the vane region 112 . The receiving portion 20 is configured to be coupled with a motor such as a moving blade 40 and a stator (not shown). The basic member is such that the bucket 4 can be located in the bucket region 111, so that when the stator rotates to drive the bucket 4, the bucket 40 can introduce airflow from the air inlet 12, and sequentially guide the The airflow passes through the bucket region 111, the vane region 112 and the collecting region, and the airflow can flow to the external space through the air outlet 13 to achieve a predetermined heat dissipation. Each of the static vanes 30 is coupled between the outer frame 1 and the receiving portion 2, for example, one end of each of the vanes 30 can be coupled to the outer peripheral surface of the receiving portion 2, and the other end can be coupled The inner circumferential surface of the outer frame 10; or one of the partial stationary vanes 30 may be selected to not engage the outer circumferential surface of the receiving portion 20 or to select the inner circumferential surface of the outer frame 10. In addition, each of the static dies 3 has a first end edge 31 and a second end edge 32, and the first end edge 31 faces the air inlet 12 of the outer frame 10, and the second end edge 32 faces the outer frame The outlet of the raft is 13. Further, in the fifth embodiment of FIG. 5 and FIG. 6 shown in FIG. 5, the embodiment of the present invention defines that the outer frame 10 has a to-reference datum (s) which is perpendicular to the movement. The axial direction of the blade 40 causes the bucket 4 to be introduced into the inside of the outer frame 10, and the airflow flowing in the axial direction is also relatively perpendicular to the horizontal reference plane (S). In addition, each of the vanes 30 has a windward surface 33 facing the air inlet 12, and the windward surface 33 has a line (L) adjacent to the second end edge 32 and the horizontal reference surface (S). An angle (0), and a subtraction (4) are preferably between six and seventy-five degrees, whereby the airflow generated by the rotation of the bucket 4 is passed through the rotor blades and the manifold region 113. 'It can be concentrated and not easy to spread. The main structural feature of the eight heat dissipation secrets of the invention is that each of the stationary vanes 30 is hidden between the second end edge 32 of the static vane 3G and the outgoing wind σ 13 of the static Wei 112 'the spurious area 113 (10). The collecting area ι ΐ 3 has a function of concentrating the flow of the air; thereby, as shown in FIG. 5, when the moving blade 40 rotates to introduce airflow from the air inlet 12, the air passes through the static After the leaf 30 directly enters the collecting area U3, so that the airflow is concentrated in the same direction by the collecting area 113, and then the air is secreted by the air outlet 13 for heat dissipation; therefore, the heat dissipation of the present invention The housing can ensure that the airflow is concentrated after the air outlet 13 is discharged, and the airflow is prevented from being generated, and the airflow is prevented from being generated between the airflows. The effect of wind pressure. In order to ensure that the current collecting area 113 has a better concentrated guiding airflow effect, please refer to FIG. 5 again. When the outer frame 10 is defined to have an axial height (H), In the axial direction of the moving blade 4G, the first end edge 32 of each of the vanes 3 至 has a -first-axis distance from 201035454 (hl) between the air outlets 13 , and each of the static slabs a second axial distance (between h2^d and the second end edge %) preferably occupies at least the first-axial distance of the axial height (H) (the hl-direction distance (10) preferably occupies the axial height ( '2|, the second axis=, the first axial twenty-axis axial distance (h2) may also be directly set; thereby, the 兮(丨) is equal to the second axis for accommodating the predetermined volume The space of the material can provide the amount of wind under the condition of the leaf into a cow = without affecting the movement, and the progress of the formation of the collecting area 113 ^ the blade 40 _ generated airflow in the available collecting area 113 The effective sputum guides ^f 3〇 and then the 叼 叼 叼 叼 导 导 导 导 导 又 又 又 又 又 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流 气流_ show the invention scattered Another embodiment of each of the static chambers 30 of the hot-seat housing is mainly formed by a partial vane and a second end edge 32 to form a baffle 321; or, depending on the entire vane 3〇 The baffle cuts are formed (treeting > each of the baffles 321 extending toward the air outlet 13 of the outer frame 10 to the current collecting area 113, wherein each of the baffles 321 can be cut as shown Or the air outlets 321 may not be aligned with the air outlets 13 (not shown) and each of the air deflectors is preferably perpendicular to the level of the outer frame 1 The reference plane (S). Thereby, after the airflow passes through the vane 30 and directly enters the collecting zone 113, the design of the deflector 321 can be utilized to make the airflow more easily concentrated toward the same direction. The diffusion of the airflow from the air outlet 13 can also be prevented. As described above, the heat dissipation fan housing of the present invention and the conventional heat dissipation housing can be applied to the fan field, when both are actually used for fans having the same power. , 201035454 The heat dissipation fan housing of the present invention can indeed utilize the design of the current collecting area 113 to enable the present invention Compared with the conventional cooling fan housing, it has the effect of increasing the wind pressure and the air volume; in other words, under the condition of the same wind pressure and air volume, the cooling fan housing of the invention is used in the fan field to achieve energy saving.
