The invention discloses
inverter type
welding equipment by using side inlet air. The
inverter type
welding equipment comprises a
front panel, a rear panel, a
rectifier and filter circuit, a control module, a driver module,
MOSFET (
metal-
oxide-
semiconductor field effect transistor) devices, an
inverter module, a
rectifier module, a high-frequency
transformer, a current regulating device, an input power line, an output port, a fan, a rack and the like. The inverter type
welding equipment is chracterized in that the fan is installed at the side of the rack, air outlets are arranged on the
front panel and the rear panel, heat-transfer surfaces of the
MOSFET devices are arranged on an identical plane which keeps close
thermal contact with one same plane of E-shaped heat sinks and forms the inverter module by being installed together with a driver plate, a rectification module and the heat sinks are installed together to form the
rectifier module, the fan is arranged above fins of the E-shaped heat sinks of the inverter module, airstream flows vertically to the fins of the heat sinks and flows along a flow channel formed by the fins of the heat sinks so as to continue to cool the rectification module and a main
transformer; the airstream is discharged out of the rack from the air outlets on the
front panel and the rear panel, so as to form the inverter type welding equipment which has
high heat dissipation efficiency,
high load rate and simple structure, and is stable and reliable.
