With rotor dispersing hot wind runner is constituted, it is fixed at least two panels blade in the rotor end plates, one between blade and rotor end plates
Body formed, blade and shaft collectively form aerofoil fan, and air is in rotor dispersing hot wind flow passage, and heat is handed between air and rotor
It changes, the shaft is hollow shaft at least open at one end, and is provided with shock absorbing ring, damping between the rotor and shaft
Interference contact is connect circle between rotor, shaft respectively；Motor-driven rotatable shaft rotation, drives the blade being mounted in rotor end plates
Rotation, so that air is circulated by rotor dispersing hot wind runner, heat exchange between air and rotor, and rotor heat is taken away,
To realize the purpose of rotor heat dissipation.
Above-mentioned technical proposal is improved further and is refined, the blade is direct by area by rotor end plates
Punch forming, blade forming is on the outside of rotor end plates.
Above-mentioned technical proposal is improved further and is refined, the blade by rotor end plates hot investment casting directly at
Type, blade forming is on the outside of rotor end plates.
Above-mentioned technical proposal is improved further and is refined, the installation number of the blade is according to the outer diameter of rotor
It is configured, is made of aluminum alloy materials or high strength composite.
Above-mentioned technical proposal is improved further and is refined, the blade in rotor end plates circumferentially radially
It is uniformly distributed, positioned at the opposite exterior lateral sides of through-hole.
The benefit of the generation of the utility model: cooperate blade construction using rotor dispersing hot wind runner, blade rotation makes to have leisure
