Abstract
Systems and methods are disclosed relating to welding-type power supplies. In some examples, the power supplies may have no vents, which may help prevent environmental contaminants from entering the power supplies. Instead, the power supplies include one or more thermal interfaces configured to conduct heat generated by internal circuitry of the power supply from the interior of the power supply to an exterior of the power supply. Additionally, the thermal interface(s) may be configured for attachment to one or more exterior heat dissipating devices.
Claims20
A welding-type power supply, comprising:
- power conversion circuitry configured to convert input power to output power suitable for welding, cladding, brazing, induction heating, plasma cutting, carbon arc cutting, gouging, hot wire preheating, or resistive preheating;
- an enclosure housing the power conversion circuitry, wherein the welding-type power supply includes no fans disposed within the enclosure;
- and
- a thermal interface in thermal communication with the power conversion circuitry, the thermal interface comprising a thermally conductive material configured to conduct heat generated by the power conversion circuitry to an exterior surface outside of the enclosure.
