Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in more detail.
Consult shown in Fig. 1, be the structural representation of embodiment of the present invention blower, described blower comprises support body 1, motor 2 and at least one vortex fan 3.Wherein, the parts of all blowers are all arranged in described support body 1.Preferably, this support body 1 adopts steel structure, can ensure stability and the Security of described blower.Preferably, motor 2 adopts high-speed electric expreess locomotive.Further, vortex fan 3 is arranged on an end of this motor 2, and described vortex fan 3 is connected with motor 2 mechanical transmission.
In an embodiment of the present invention, described blower operationally, high-speed electric expreess locomotive 2 is utilized to drive vortex fan 3, make air after the intake grill suction of vortex fan 3, flow through the impeller of vortex fan 3, formation increasing temperature and pressure is compressed through the impeller of vortex fan 3 and the shell friction of vortex fan 3, then by the exhaust outlet ejection at a high speed of vortex fan 3.
Preferably, described blower also comprises base 4, is arranged on the lower end of motor 2, and motor 2 can be made to produce distance with the bottom of support body 1.
Preferably, described blower also comprises control cabinet 5 and cable 6.Be provided with frequency variator in this control cabinet 5, frequency variator is connected with motor 2 by cable 6, is used for controlling motor speed, thus the air force of controlled vortex flow blower fan 3 exhaust outlet.In addition, be provided with temperature control box in this control cabinet 5, temperature control box is connected with the exhaust outlet of vortex fan 3 by cable 6, is used for the temperature of controlled vortex flow blower fan 3 exhaust outlet.In an embodiment of the present invention, at the exhaust outlet place of vortex fan 3, low profile thermal galvanic couple is housed, is connected with temperature control box by cable 6.Temperature control box arranges required temperature, feeds back to frequency variator and goes to control motor 2 rotating speed.
As an alternative embodiment of the invention, consulting shown in Fig. 2, is the structure sectional view of embodiment of the present invention vortex fan and high-speed electric expreess locomotive.Described high-speed electric expreess locomotive 2 comprises rotor 201, air hydrodynamic bearing 202, coil 207 and iron core 208, is separately installed with described air hydrodynamic bearing 202 at the two ends of this rotor 201.Iron core 208 is arranged on the outer wall of rotor 201, and described coil 208 is wrapped on this iron core 208.
