High-speed magnetic suspension air blower electrically-controlled element radiating system

Abstract

The invention provides a high-speed magnetic suspension air blower electrically-controlled element radiating system. The system comprises a sound insulation cover, an air blower, a base, a flow collector, an air pressure silica gel expansion joint and a runner flow guiding cone; the sound insulation cover is fixed at an upper end of the base, the air blower is fixed in the sound insulation cover through a bolt, the flow collector is fixed at a left end of the air blower, and the runner flow guide cone is fixed in the sound insulation cover. Through the design provided by the invention, the useis convenient, the extra power supply is avoided, the inlet negative pressure of the air blower main impeller is utilized, and the running efficiency of the whole machine can be further improved; themagnetic bearing controller and frequency converter design control of the high-speed magnetic separation air blower is simplified, the system stability is improved, the axle flow air blower is removed, the use cost is lowered, and the system integration structure is simplified.

Description

technical field [0001] The invention relates to a heat dissipation system for an electric control element of a high-speed magnetic levitation blower, and belongs to the technical field of magnetic levitation blower equipment. Background technique [0002] At present, the high-speed magnetic levitation blower magnetic bearing controller and the inverter cooling device are mainly equipped with an axial flow blower to dissipate heat for the controller and the inverter. The operation of the axial flow blower will increase the instability of the magnetic bearing controller and the inverter equipment. Usually, in order to cope with the sudden failure of the axial flow blower, the number of axial flow blowers is increased, which will increase the power consumption of the whole machine, and the air filter is directly fixed on the equipment, which is extremely inconvenient to disassemble and repair. decrease productivity.
