That is, the bottom wall of the disk holder 121 and the top wall of the housing 112 have a gap therebetween, and the gap is formed with a third passage 1113.

The sum of the air outlet areas of the second air outlets 1131 is greater than or equal to the sum of the air inlet areas of the second air inlets 1211 minus the sum of the air outlet areas of the third passages 1113. As a preferred embodiment of the present invention, the total air-out area B1 of the second air outlet 1131 is greater than the total air-out area B of the third channel 1113, so as to ensure that the cold air flowing out of the first air outlet 1122 smoothly enters the second channel 1112 from the second air inlet 1211 and is prevented from flowing from the third channel 1113 to the second air outlet 1131. Air flowing from the second channel 1112 to the second outlet 1131 is also prevented from flowing to the second inlet 1211 and/or the first outlet 1122 through the third channel 1113.

As a preferred embodiment of this embodiment, after flowing into the first channel from the first inlet 1121, it flows into the third channel 1113 from the first outlet 1122, then flows into the second channel 1112 from the second inlet 1211, and then flows toward the second air channel 211 from the second outlet 1131. Thus, the outer magnetic disc assembly 12 can fully dissipate heat to reduce the temperature of the magnet 122, prevent the magnet from demagnetizing, and prolong the service life of the outer magnetic disc assembly 12.
Further, referring to fig. 3 and 4, a plurality of heat dissipating ribs 1212 are convexly disposed on the bottom wall of the outer magnetic disc assembly 12, the heat dissipating ribs 1212 are radially arranged to disturb the airflow in the first air duct 111, and the heat dissipating ribs 1212 are in a shape of a sheet or a vane. It can be understood that the heat dissipating ribs 1212 are located in the first air duct 111, and a plurality of heat dissipating ribs 1212 are convexly disposed on a side of the bottom wall of the disk support 121 facing the protective cover 113, where the heat dissipating ribs 1212 are arranged in a radial fan shape. At this time, each of the second air inlets 1211 is disposed between two adjacent heat dissipation ribs 1212. The bottom wall of the disk holder 121 is provided with the heat dissipating ribs 1212 arranged radially, so that when the disk holder 121 rotates along with the motor 13, the heat dissipating ribs 1212 form turbulent flow on the bottom wall of the disk holder 121, which is similar to a fan, so that the first accommodating groove 124 of the outer disk assembly 12 generates pressure, and thus the cool air flowing out of the first air outlet 114 is smoothly introduced into the second channel 1112 through the second air inlet 1211.
Specifically, the projection of each heat dissipating rib 1212 on the bottom wall of the outer disk assembly 12 is a straight line, an arc line or a curve. Preferably, as shown in fig. 3 and 4, the projection of each heat dissipation rib 1212 on the bottom wall of the disk holder 121 is arc-shaped, which is beneficial to better form a turbulent flow effect on the bottom wall of the disk holder 121 by the heat dissipation rib 1212 when the disk holder 121 rotates with the motor 13, so that the outer disk assembly 12 can fully dissipate heat, and the demagnetizing phenomenon of the outer disk assembly 12 is avoided.
