Abstract
The utility model discloses a frequency converter single-fan structure, which comprises a casing. The casing is provided with a power input interface; a fan control panel connected with the power input interface is mounted in the casing; and a fan is mounted under the fan control panel and connected with the fan control panel. As the single cylindrical fan is mounted under the fan control panel, the number of fans to be used is decreased, cost is reduced, wind pressure is increased, the fan control panel is capable of blowing from an upper hollow area through the fan, and the frequency converter single-fan structure has fine heat dissipation effect.
Description
Technical field:
The utility model relates to frequency converter, and what be specifically related to is a kind of frequency converter list blower fan structure, is mainly used in the heat radiation of frequency converter.
Background technology:
Frequency converter is the AC power that power frequency supply (50Hz or 60Hz) is transformed into various frequencies, to realize the equipment of motor speed-changing operation, wherein control circuit is finished the control to main circuit, rectification circuit is transformed into direct current with alternating current, DC circuit is carried out smothing filtering to the output of rectification circuit, and inverter circuit becomes alternating current with direct current another mistake.
In the now common frequency converter, blower fan generally adopts a plurality of, and is installed in the top of transducer control circuit plate substantially, and it exists that blast is low, cost is high and problem such as radiating effect difference.
Summary of the invention:
For this reason, the purpose of this utility model is to provide a kind of frequency converter list blower fan structure, has to solve present frequency converter that blast is low, cost is high and the problem of radiating effect difference.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of frequency converter list blower fan structure, comprise housing (1), described housing (1) is provided with power input interface (4), the blower fan control board (2) that is connected with this power input interface (4) is installed in the housing (1), one blower fan (3) is installed under the blower fan control board (2), and this blower fan (3) is connected with blower fan control board (2).
Wherein said blower fan control board (2) is provided with power input unit (201), rectification unit (202), inversion unit (203), charhing unit (204), filter unit (205) and power supply output unit (206), described power input unit (201) is connected with rectification unit (202), rectification unit (202) is connected with filter unit (205) by charhing unit (204), and filter unit (205) is connected with power supply output unit (206) by inversion unit (203).
Wherein said blower fan (3) is the monomer cylindrical shape.
The utility model with monomer cylindrical shape blower fan be installed in the blower fan control board under, reduce the usage quantity of blower fan, reduced cost, improved blast, and the blower fan control board can directly spacious zone blows out from top by blower fan, has better heat radiating effect.
