FIELD: technological processes. ^ SUBSTANCE: invention is related to welder inverter source and may find application in electrical engineering. Source body includes base, front and back panels with ventilation grates, detachable cover with side walls, and separating panel installed horizontally relative to base. This panel is fixed between front and back panels, which are joined to base and detachable cover to create an upper compartment. High-voltage and low-voltage electronic components are installed in upper compartment. Lower compartment is arranged in the form of air duct, which is equipped with fan and at least the first and second radiators for cooling of the following components installed in it - power transformer, throttles and power rectifying modules. Separating panel has an opening for installation of the first radiator with its flat horizontal surface inside the upper compartment. The first and second radiators are installed with vertical location of fins relative to base and are fixed on separating panel with longitudinal installation of fins relative to air flow direction from fan. The second radiator is fixed with vertical displacement relative to separating panel with creation of gap. Power rectifying modules are installed in specified gap on flat horizontal surface of this radiator. ^ EFFECT: higher reliability of source operation. ^ 9 cl, 9 dwg |
