Welding Type Power Supply With Wind Tunnel
First Claim
Patent Images
1. A welding type power supply comprising:
- an outer housing;
a wind tunnel, disposed within the outer housing, having an air flow direction, and a first cross direction perpendicular to the air flow direction, wherein a first width of the wind tunnel in the first cross direction at a first location in the air flow direction is less than a second width of the wind tunnel in the first cross direction at a second location in the air flow direction; and
electrical components disposed to receive power and provide a welding type output, wherein the electrical components include a first group of components that require air flow for cooling, and a second group of components;
wherein the first group of components are disposed at least partially in the wind tunnel and the second of components are not disposed in the wind tunnel.

Abstract
A method and apparatus for providing a welding type power is disclosed. It includes an outer housing having a wind tunnel within the outer housing. Air flows through the wind tunnel in an air flow direction. The width of the tunnel is less at one location than at another location. Electrical components receive power and provide a welding type output. A first group of those components require air flow for cooling, and are disposed at least partially in the wind tunnel. A second group of components are not disposed in the wind tunnel. The wind tunnel can also change direction.
