The flow channel defines a first through hole and a second through hole on both sides of the frame body. The frame body is formed on the side of the frame through the first through hole and has a first frame wall which is inclined and radially outwardly diffused, and is close to The second through hole side is formed with a second frame wall which is opposite to the first frame wall, wherein the first frame wall is outwardly diffused to at least exceed the floor and the first frame wall and the first The second frame wall is connected with a third frame wall which is not inclined. The above and other structural and functional features of the present invention will be described in accordance with the preferred embodiments of the accompanying drawings. The present invention is directed to a "fan unit", which is a preferred embodiment of the present invention. Please refer to the first to fourth embodiments as a preferred embodiment of the present invention, which includes at least one a frame η and a fan wheel 12, wherein the frame body η has a flow passage through the frame body 11, and the flow channel defines a first through hole 111 and a second through hole on both sides of the frame body η. And the at least one through hole 113 is formed in the through hole 113 of the frame body, and the through hole 113 is disposed through the at least one fixing element 1275240. The inner side of the frame body 11 is formed near the first through hole HI. The outer frame 11 is inclined and radially outwardly diffused to at least exceed the first frame wall 114 of the frame 11 and the through hole 113 of the frame 11 , and is formed adjacent to the second through hole 112 side. a second frame wall 115 is inclined in a direction opposite to the first frame wall 114. The third frame wall 116 is non-inclinedly connected between the first frame wall 114 and the second frame wall 115. 13 is disposed in the frame body u adjacent to the second through hole 112 side, and at least one supporting member 131 is connected to the periphery of the hub seat 13 and the second Between the frame walls 115, a hollow shaft tube 132 is formed on the hub seat 13, and the shaft tube 132 is provided with at least one bearing 14 and a buckle body 15, and the shaft tube 132 is provided with a motor stator 16 sleeve. The fan wheel 12 has a hub 121 and at least one fan blade 122 extending outwardly around the hub 121. The hub 121 is provided with an axial center mu and a motor rotor 17 (as shown in the fourth figure). When the assembly is assembled, the shaft 1211 is inserted through the bearing 14 in the barrel 132 and the buckle 15 is fastened to the shaft 1211, so that the fan wheel 12 is movably pivoted on the hub seat 13, The motor stator 16 is magnetically coupled to the motor rotor 17. The through hole 1 is connected to the first frame wall 114, and the first frame wall 1H and the second frame wall 11s are not equal in length, and the fan wheel U of the first frame wall 1M is outwardly diffused. Therefore, the size of the closing wheel u can be increased. Referring again to the fourth and fifth figures and with reference to the first figure, when the motor stator 16 1285240 and the motor rotor 17 are excited, a physical transformation is made into kinetic energy to drive the motor rotor 17 to rotate, and then the genus 12 is driven. Rotating, at the same time, driving the fluid to flow from the first through-hole m. 'Because the first frame wall 114 radially outwardly exceeds at least the through hole 113 of the body u and its four turns, the fluid of the first through hole iu flows into the body_ Increasing, (4) the flow rate of the first-view m red increases, and when the fluid passes through the third frame wall μ, the pressurized side is generated via the fan blade 122 and the third frame wall 116#, thereby accelerating the flow rate of the face. When the fluid flows through the second frame wall 115, the flow is outwardly diffused by the inclination of the second frame wall 115, and the heat dissipation area of the flow can be increased, and the first frame wall 114 is inclined to be large. Reducing the noise generated by the direct impact of the fluid directly on the first frame wall 114 (i.e., the fluid can flow along the inclined wall of the first frame wall 114) and the noise generated by the uneven flow area, and the through hole 113 Directly through the first frame wall 114, greatly improving the yield in the process, Moreover, the problem that the conventional fan has a through hole in a thin wall and the opening of the wall is very fragile B is improved. Since the first frame wall 114, the second frame wall 115, and the third frame wall 116 of the frame 11 are used to generate a three-stage action of the fluid, that is, 1) increase the flow rate of the fluid; Flow speed; 3·Enlarge the heat dissipation area of the fluid; greatly improve the heat dissipation efficiency to improve the problem that the conventional air inlet is too small, resulting in easy noise generation and insufficient heat dissipation performance. Furthermore, as shown in the sixth and seventh figures, the second frame wall 115 can be formed with the first frame wall 1285240 === the first, 114 is up and down, and the above-mentioned "fan unit" "According to the requirements of the permit", please make a special offer in accordance with the law, please pray for the patent, but the above is only the preferred embodiment of the present invention.
