Example two

Compared with the first embodiment, the difference of this embodiment is that:

referring to fig. 3, the heat conduction wheel 4 is a first heat conduction wheel 401.

The blades of the first heat conduction wheel 401 are wave blades 4011, the axial section of each wave blade 4011 is wave-shaped, and the assembly angle of each wave blade 4011 and the inner ring is equal to the axis of the inner ring;

a plurality of gaps 4012 are symmetrically arranged on the outer ring by taking the radial center axis of the first heat conduction wheel 401 as a reference, and the positions of the gaps 4012 correspond to the gaps of the adjacent wave blades 4011.

From the aspect of the airflow flowing process, the design is a diversion mode of active suction and passive discharge.

Example III
