[Prior Art] According to a type of motor, as shown in the fifth figure, a motor body (20) is disposed on the outer casing (40), and the motor body (20) has an output shaft extending from each end. (21) (22), the two output shafts (21) (22) are combined with an impeller (30) having a plurality of blades (32) arranged in a circular wheel shape, the impeller (30) being a fixed plate at the center of the interior (31) ), the fixed plate (31) is connected to the output shaft (21) (22), so that the motor body (20) drives the two impellers (30) to rotate, and the outer casing (5〇) covers the impeller (30), and is left At the outlet of the outlet (41), the outer seat (5〇) is adjacent to the motor (20), corresponding to the impeller (30) to form the air inlet (42), the motor body (20) is fixed at the end faces respectively A motor cover (5〇). Therefore, when the motor body (20) drives the impeller (30) to rotate, the wind is brought into the impeller (30) by the air inlet (42), and a wind is generated to be sent out by the air outlet (41). In the foregoing configuration, the heat dissipation performance of the motor body is not good. Since the wind contact area of the motor body and the air inlet is small, only close to the outer circumference of the end portion of the air inlet, and the air volume of the motor cover contacts is small because the axial contact area is short, so the heat dissipation efficiency of the motor body Poor, this will affect motor power and performance. • M322677 [New Content] The creator of this creator has carefully studied and developed in view of the above problems. Therefore, the main purpose of this creation is to provide a motor heat sink which is mainly provided with a plurality of axially extending fins on the motor cover of the motor body. The sheet is used to increase the contact area of the inflow air volume, thereby effectively improving the heat dissipation efficiency of the motor body. In order to achieve the foregoing objectives, the technical means employed in the present invention is to provide a motor heat sink which is a motor body having at least one wheel output shaft, the output shaft of the motor body drives an impeller, and the impeller is in the inner center. Forming a fixing plate for connecting the wheel-out shaft, and the motor owning the end surface of the output shaft, and providing a motor cover plate having a base plate and a plurality of fins, the center of the substrate is for the output shaft to pass through, and The substrate extends a plurality of fins axially toward the impeller, each of the fins extending into the impeller, and the fixed plate maintains a safe distance without interference. Therefore, according to the technical means of this creation, the brief descriptions of the functions that can be obtained by this creation are as follows: This creation is mainly based on the extension of the motor cover of the motor at the end of the ship, especially the extension length of the recording film is entered into the impeller. The wind entering the wind is subjected to the impeller agitation process, so that the axial contact area of the fins allows the incoming air to follow the flow path formed by the fins, and fully contacts the recording film, so that the long and wide fins have sufficient The contact area can greatly improve the heat dissipation performance of the motor body, extend the service life of the motor, and maintain the operating power of the motor. [Embodiment] The present invention is a motor heat sink, as shown in the first and second figures, the basic type is the same as the conventional one, the housing seat (40) is fixed to the motor body (20), and the M3^2677 motor body (20) The output shafts (21) and (22) extending to the outer ends of the impellers (30) are respectively provided with a plurality of blades (32) on the side of the fixing plate (31) of the fixed plate (31), and the motor (20) The two impellers (3 turns) can be driven to rotate, the outer casing (4 〇) covers the impeller (30), and an outlet air outlet (41) is left, and the outer casing (4 〇) is adjacent to the motor body (20) respectively. The impeller (3 turns) forms an air inlet (42). The main feature of this creation is that the motor body (2〇) is fixed with a motor cover (1〇) with several fins (12) on both end faces to improve the heat dissipation efficiency of the motor. The motor cover (10) is further as shown in the second and third figures. The motor cover (10) has a base plate (11), and the base plate (11) has a hole for the output shaft (21) (22) to pass through. The convenient output shaft (21) (22) is coupled to the impeller (30), and the substrate (11) is oriented toward the impeller (30), and the fins (12) are axially extended. The extension of the fins (12) is to enter the impeller ( 30) inside, and the longest position is a safe distance that does not interfere with the fixed plate (31). And the outer shape of each fin (12) arranged on the motor cover plate (1〇) may be a tapered shape, that is, the axial length of each of the chips (12), from the outermost side of the radial surface of the substrate (π) toward the center The portion is gradually enlarged, so that the groups of the fins (12) are formed into a tapered shape, and the fins (12) are extended in length and in the outer diameter range, and can be symmetrically matched to the inner shape of the impeller (30). As shown in the second figure, after the wind enters the air inlet (42), since the creation is intentionally arranged in the axial length of the fins (12) of the motor body (20), the guiding wind is along the contact fins (12). The axial extension of the area, with the impeller (3 〇) agitating wind, effectively increase the contact area of the wind motor body (20), so that the wind from the air inlet (42) to the air outlet (41) blast process, the motor body (20) Also 7 M322677 achieves excellent heat dissipation efficiency at the same time, greatly improving heat dissipation performance. The above embodiments are merely illustrative of the techniques and effects of the present invention, and are not intended to limit the present invention. Anyone skilled in the art can implement the above without departing from the technical principles and spirit of the present invention. Modifications and changes are made to the examples, so the scope of protection of this creation should be as listed in the patent application scope mentioned later. ‘M3, 22677 BRIEF DESCRIPTION OF THE DRAWINGS (I) Schematic Part The first figure is a three-dimensional appearance of the preferred embodiment of the present invention.
