First Claim
Patent Images
1. A wind tunnel for a welder comprising:
- a base of a welding-type power supply;
front and rear end panels mounted on opposite ends of the base, each having an opening therein; and
a U-shaped panel mounted to the base and attached about the openings of the front and rear end panels, the U-shaped panel having two side portions and a top portion, wherein at least one of the side portions has therein a slot to receive a component inside the U-shaped panel to form a substantially closed tunnel from the front panel to the rear panel.

Abstract
A system and method for a welding power supply housing is disclosed. The power supply housing includes a U-shaped panel positioned between two louvered end panels and a base. The combination of the U-shaped panel and the base forms a wind tunnel. The U-shaped panel includes a slot configured to receive a heat sink. The heat sink is in thermal connection with heat generating electrical components of the power supply and is exposed to the cooling flow within the wind tunnel thereby cooling the electrical components of the power supply.
