Therefore, in order to avoid affecting the operation efficiency of itself and the board unit due to excessive temperature, Burning, a cooling fan will be added to the assembly to assist in heat dissipation. Referring to FIG. 1 ' generally used for heat dissipation of an electronic component such as a central processing unit, a similar processing unit, or a chipset, the external cooling fan 9 is mainly provided by a housing 91 and a housing 91. The fan wheel 92 is formed on the housing 91 and covers the outer frame 93 of the fan wheel 92. The housing 91 has a plurality of pole posts 9n, and the fan wheel 92 has a magnet ring 923 attached to the outer edge of each of the blades 922. The conventional external heat radiating fan 9 is disposed on the heat dissipating fin group 8 to dissipate heat from the heat generating element=7. In the material, the poles 910 are energized, so that each pole 911 and the magnet ring 923 generate an electromagnetic effect to sense each other, and the operation of the magnet ring 923 drives the rotation of each _ riding M2, that is, The heat generated by the heat-generating electronic component 7 is absorbed by the heat-dissipating fin group 8, and then released by the heat of the fan-wheel 92 to release the heat fins, thereby achieving auxiliary heat dissipation. The cooling fan 9 must be used in conjunction with 20 1257974, 'and. Further, on the heat-dissipating fin group 8, the heat-dissipating fin group 8 can be added to the heat-generating electronic component 7 to increase the overall thickness and increase the assembly space, which limits the space utilization. In addition, the overall thermal conductivity effect is also due to the addition of the heat-dissipating cymbal group 8 and the multi-layer medium, the U fruit is not good. In addition, the operating frequency of electronic components such as central processing units, similar computing processing units, or chipsets used in the technology industry at this stage has increased, resulting in higher heat generation of these electronic components during operation. Therefore, how to more effectively improve the heat dissipation function of the externally exposed external fan, in order to improve the overall heat dissipation effect, is an important issue for the active research and development of the industry today. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an extreme cooling fan that can effectively improve the overall heat dissipation effect while reducing the overall thickness to save space. 15 & is an external pole type heat dissipating fan of the present invention, which is suitable for dissipating heat from a heat generating component, comprising: a housing, a fan wheel disposed on the housing, and a cover disposed on the housing The fan wheel outer frame has a heat dissipation shaft plate that can be coupled to the heating element, and the heat dissipation vehicle is made of a plate and a fan wheel: the fan blade group is made of a heat conductive material. The heat absorbing plate and the mandrel 20 are used to form a good heat absorbing body to absorb heat energy, and then transmitted to the fan blade group of the fan wheel, and at the same time, the fan wheel is operated to improve the heat dissipation efficiency, and because it is directly transmitted to the heat dissipation plate It is then directly discharged through the fan blade group, so the overall heat dissipation effect is excellent. In addition, the design of the present invention is not required to be combined with the heat-dissipating set, so that the overall thickness is thinned and the height is greatly reduced, and the available space is more flexible than 1257974. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the preferred embodiments.

Referring to Figures 2 and 3, a first embodiment of the external heat sink fan i of the present invention is suitable for dissipating heat from a heat generating component 2 (shown in Figure 3) 10 such as a central processing unit, the external pole cooling fan 1 comprising : a shell u, a wheel 12, and an outer frame 13. The housing 11 has a heat dissipation plate 111 that can be coupled to the heating element 2, a seat plate 112 that is disposed around the periphery of the heat dissipation plate 1U, and a bracket 113 that connects the heat dissipation plate 111 and the seat plate 112. The air outlet 11 is defined by the distance between the heat dissipation 15 shaft plate 111 and the seat plate H2, and a plurality of magnetic poles 114 are disposed on the seat plate 112. In the present embodiment, the heat dissipation shaft plate 111 may be made of a heat conductive material such as copper or aluminum which has a relatively good heat dissipation effect. The 5th fan wheel 12 is not disposed on the heat dissipation plate ill of the housing 11. The fan 20 wheel 12 has a spindle 121 erected on the heat dissipation plate 111, and is pivoted on the spindle 121. A blade set 122 that is rotatable relative to the mandrel 121, and a ring of magnets 123 disposed on the periphery of the blade set 122. In the present embodiment, the mandrel 121 and the blade group 122 may be made of a heat conductive material such as copper or aluminum which has a relatively good heat dissipation effect. 1257974 The outer frame 13 is disposed on the housing 11 to cover the fan wheel 12, and the outer frame 13 has a frame 131, and an air inlet 130 disposed on the frame 131 corresponding to the fan wheel 12 And a plurality of brackets 132 disposed on the frame 131 and corresponding to the air inlet 130. As shown in FIG. 3, the exception-type heat-dissipating fan 1 of the present embodiment is disposed such that the heat-dissipating shaft 111 of the housing 11 is attached to the heating element 2, and the heat-dissipating shaft 111 is directly connected to the heat-generating component 2. Contacting and absorbing the thermal energy conducted by the heating element 2. In use, the magnetic poles 114 of the housing 11 are also energized, so that each of the magnetic poles 114 and the magnet ring 123 of the fan wheel 15 12 are electromagnetically induced to each other, and the magnet ring 123 is operated. By driving the blade group 122 to rotate, the gas flow can be driven to achieve the purpose of cooling air. In particular, the heat dissipation shaft plate lu is made of a heat conductive material. When the heat generating component 2 is gradually heated, the heat energy released by the heat generating component 2 is immediately absorbed by the heat dissipation shaft plate ln, and the fan wheel 12 is reused. The operation of the airflow introduced from the air inlet 13 of the outer frame 13 causes the heat flow on the heat dissipation plate 111 to be carried out by the air outlet 丨1 of the casing, thereby achieving the purpose of dissipating heat of the driving gas (4). Therefore, the external-pole cooling fan i is not required to be disposed as in the conventional external-type cooling fan, and the heat-dissipating fin assembly can be used to dissipate the central processing unit 2 on a heat-dissipating fin group. hP uses components such as heat sink fins to achieve easy assembly and space saving. In addition, the straw from the fan wheel 12 is 121 and the fan blade group 122 is also the heat material; #丄" § The heat is not completely blown to the outside and rises to the heat! Above the heat dissipation plate 111 'Using the mandrel 121 and the blade group 12 20 1257974 are both made of a heat conductive material and have good heat conduction conditions, and absorb the residual heat hovering above the heat dissipation plate 111 again, and make the 122 absorb heat. At the same time, the residual heat is blown off from the air outlet 110 of the casing 11 to the outside. Therefore, in the present invention, the heat dissipation shaft plate lu and the mandrel 121 and the blade group 122 can respectively absorb the heat energy, and at the same time, when the blade group 122 is operated, the heat energy is blown out, so that the double auxiliary heat dissipation can be achieved. The function enhances the overall heat dissipation. Ben Sheming's external pole cooling fan Cang Ying ίο 15 cases also include: - shell 1 b - fan wheel 12, and - frame 13. The first embodiment is characterized in that the case 11 further has a first heat sink 115 on the plurality of convex heat dissipation fins 111, and each of the first heat sinks 115 is made of a heat conductive material. When the heat energy released by the heat generating component 2 is absorbed by the heat dissipation shaft plate 1U, the heat absorption effect of each of the first heat sink sheets 115 protruding from the heat dissipation shaft plate 111 is matched, thereby having better heat dissipation effect. . (4) The remaining side of the heat-dissipating plate 111 may be raised when the residual heat of the king's government has not risen to the outside of the heat-dissipating plate 111; the mother: the younger one between the fins 115, and when the fan wheel 12 is in operation, - The heat remaining in the 1st and 115th rooms is blown away from the exit 110 of the shell U to the outside world, so it is better to have two 丄田凤1, thus improving the overall heat dissipation effect. Referring to Figures 6 and 7, the third and third examples of the external heat-dissipating fan 1 of the present invention also include: a saki η η ... Λ 11, a fan wheel 12, and an outer frame 13. The disc, 1Q, is that the outer frame 13 further has a plurality of cymbals arranged on both sides of each bracket 132, and a mother heat sheet 133, and each second slab sheet is made of a heat conductive material. . , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , And the good heat absorption effect of the second heat release sheet 133 disposed on both sides of each bracket 132 can cause the residual heat that has not been completely blown to the outside to rise above the heat dissipation shaft plate ln or rise above the blade group 122 At the same time, the heat absorption of the second fins 133 can be utilized, so that the residual heat rising above the blade group 122 can be absorbed by each of the second fins 133 and blown away by the air outlet m of the housing 11 To the outside world, it can improve the overall heat dissipation effect. As described above, the external pole type heat dissipating fan 1 of the present invention is designed such that the squeaking seat 11 has a heat dissipating shaft plate 111 which can be coupled to the heating element 2 such as the central processing unit, and the heat dissipating shaft board U1 and The mandrel of the fan wheel 12 and the blade group 122 are all made of a heat conductive material. The invention utilizes the good heat-dissipating condition of the heat-conducting material, so that the heat energy of the heat-generating component 2 is the heat-dissipating plate 111 and the heat-dissipating plate 111, and then cooperates with the operation of the fan wheel 12 to discharge heat, thereby achieving the function of multiple auxiliary heat-dissipating, thereby improving the overall heat radiation. In addition, the present invention does not need to be configured with a heat dissipating fin group to achieve a heat dissipating function, so that the overall thickness can be reduced, the height is greatly reduced, and the available space is larger and more flexible. It is indeed possible to achieve the object of the present invention.
