Description of the Invention: [Technical Field] The present invention relates to a heat dissipation fan which is applied to a servo, and more particularly to a heat dissipation fan which improves the heat dissipation efficiency of a server. [Prior Art] In recent years, due to the rapid development of computers, the price of many computer devices has been greatly reduced. The design of servers is also the same, so computers have become a must-have item in most people's daily lives. The general-purpose vestibule will have a touch-up rack, and the feeding machine rack can be detachably set on the host L (four) rack material with a recording electronic device for use, such as: hard disk drive And so on, because the height of the rack of the feeding machine has a certain specification, in order to increase the space, there is not much space in front of the electronic device, and the electronic device often has heat generated during the operation. Therefore, how to use the heat-dissipating technology to heat the heat generated by these electronic devices, the height of the specification is low, and the space around the electronic device is narrow and the space is small, and the heat dissipation efficiency is one. Great learning. Please refer to the cross-sectional view of the scorpion scorpion device installed in the server rack in the "Picture 1". The server rack 10 is equipped with a hot-swappable hard disk. The disk drive 20 and the turbo fan 30 provided for dissipating heat, so that the heat generated during the operation of the machine 20 can be released from the servo with the rotation of the turbo fan 30. It is clearly seen that the turbine fan 30 has a housing 31, a glaze s glaze 32, and a plurality of fan blades 33. The rotation axis 32 is disposed 1275343 and is small and the fan blades 33 extend outward from the rotation axis 32. And because the length of the axis of rotation is short, so the fan blade for rotating to bring out heat, the area of the fan blade that can be used to cut the air is also the phase. So, we can know that the fan fan 3 heat efficiency In view of the above problems, the main object of the present invention is to provide a cooling fan applied to a rack-type ship to greatly improve the heat dissipation efficiency of the server. The disclosed cooling fan, It is used in the ship-frame, which is used for the operation of the green electronic device. The heat-dissipating fan includes a rotating shaft center and a plurality of fan blades. The rotating shaft center is composed of interconnected main shafts and extending shafts. Including the rotating device, the heat source is radiated in a direction perpendicular to the axis of the main axis of the rotating shaft at most equal to the axial length of the extending shaft. That is, the total length of the rotating shaft is more than twice the length of the main shaft. The fan blades are connected to the peak and An extension shaft, wherein the wind direction of the heat dissipation fan is a radial 'wind sheet' of the rotation axis, and the wind is taken from one side of the rotation axis to the other side in a direction perpendicular to the rotation axis. Therefore, the present invention The special design of the extended shaft with a smaller diameter of the rotating shaft center will greatly increase the cutting air area of the fan blade, because the area of the cutting gas of the fan blade extending outward from the autonomous axis and the extending axis is more than The cutting air area of the fan blade which is only extended from the bee, and the cutting air area of the fan blade can be increased by increasing the axial length of each of the extending shafts. Therefore, in the servo cradle with the electronic device and the small heat dissipation space, the heat dissipation efficiency of the ship can be greatly improved, and the electronic device 1273533 can be operated smoothly.

However, due to the side rate of the test (4), a number of thirsty wheels are used. The fan 3 is achieved, however, because the design of the full-wheel fan 3 is tender, and the _ direction is parallel to the rotation axis 32, the fan blades 3 of the respective turbine fans (10). The cut area can only be designed by using the space beyond the axis of the rotation axis, so it can be seen that the heat dissipation efficiency achieved by the fan 3G is not good. Please refer to the section of the conventional electronic «shown in the "!" diagram for the __. Because of the need to increase the heat dissipation efficiency of the cooling fan in the server, the key is to increase the cutting of the fan blades. The reason for the area is to redesign the cooling fan to increase the cutting air area of the fan blades. 2 is a perspective view of a heat dissipating fan of the present invention shown in a cross-sectional view of an electronic device according to an embodiment of the present invention, and a third embodiment. There are a plurality of hot-swappable hard disk drives in the servo rack 1 and a cooling fan provided with (4), so that the recording of the hard disk drive can be performed with the heat dissipation. The rotation of the fan (10), 7 Ϊ 275343, is taken out of the servo. The heat dissipating fan 40 disclosed in the present invention can be clearly seen from the figure, and has a casing 41, a rotating shaft center 42, and a plurality of fan blades 43. The rotating shaft center 42 is disposed on the outer casing 41. The heat dissipating direction 21 of the heat generated by the electronic device is a vertical rotating shaft center 32, and the rotating shaft center 42 is composed of an integrally formed main shaft 421 and an extended vehicle shaft 422. The diameter is larger than the diameter of the extension shaft 422, and the axis of the main shaft 421 is equal to the length of the shaft of the extension shaft. Wherein, the rotating device included in the main shaft is a fan motor. Fig. 4 is a cross-sectional view of the main shaft 421, and the fan motor 5 is mounted in the main shaft to rotate the rotating shaft 32 during operation. The fan blade 43 W is coupled to the main shaft 421 and the extension shaft 422, and the air blowing direction of the cooling fan is the radial direction of the rotation axis, and the wind is brought from one side of the rotation axis 42 to the other side. The special design of the small extension shaft 422 passing through the rotating shaft, 43 straight, will greatly increase the cutting air area of the fan blade 43, which is the autonomous shaft 421 and the extension shaft 422 - and is extended to the fan blade 43 The air area is inevitably larger than the cutting air area of the fan blade 43 that extends only from the autonomous axis. Moreover, the cutting air area of the fan blade 43 can be increased by simply extending the length of each of the cooling fans (4). Of course, as can be seen from "Fig. 2", compared to the "fan" fan%, the main axis of the cooling fan 4 is still equivalent to the size of the moving shaft (n) of the fan (4), and the hot air (4) The extension shaft 422 can be made using a _ to the outside of the main axis to thereby have a higher cutting air area on the blades 4 . Moreover, unlike the conventional technology, the rotating wheel of the turbofan 30 is locked by the shaft 32. Many of the space in the turbo fan 3G is added to each of the servo racks 20 _ _ _ λ α, Τ 3 There are a lot of sigh turbine fans 30, so I know: 1275343 Intraoperative servo stalks 2 smashed to the heart 32 (10) handsome. However, in comparison, the main shaft 421 of each of the cooling fans 40 of the present invention requires only a small amount of space in the cooling fan 40, and the number of the cooling fans 40 provided in the server rack 20 is small. In the present invention, the main frame of the server rack 2 is only required to use a relatively small amount of space, and the space saved by these can be used to improve the remaining efficiency. The hard disk drive 20 and the server rack 20 having a small heat dissipation space greatly improve the heat dissipation efficiency of the server, and allow the hard disk drive 20 to operate smoothly. With such a design, the recording of the cooling fan 4 () of the servo money is greatly reduced, so the cost of detecting the failure of each cooling fan 4 can be greatly reduced. It is known that the space of the cooling fan 4〇 of the present invention is three to five times the space used by the conventional turbo fan 3〇, but the figure is self-illustrated. In the present invention, the area of the cutting air of the fan blade 43 is greatly increased. Although the present invention has been disclosed in the above preferred embodiments of the present invention, it is not intended to limit the invention, and those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The dumping of the present invention is subject to the definition of the patent application bribe.
