Abstract:
A power supply apparatus for supplying electrical power for a piece of equipment that produces an electrical arc, the power supply apparatus comprising:a housing having at least one air inlet and at least one air outlet;an air moving device for moving cooling air from the air inlet to the air outlet along a flowpath extending through the housing; anda heat dissipator extending in a longitudinal direction, positioned along the flowpath, and comprising an upstream portion and a downstream portion, wherein the heat dissipator is oriented along the flowpath so that an upstream section of the flowpath is proximate to the upstream portion of the heat dissipator,said flowpath having a flow axis that forms an acute angle with respect to the longitudinal direction such that air flowing from the upstream section of the flowpath impinges upon and is deflected by the heat dissipator so as to create a downstream section of the flowpath that is proximate to the downstream portion of the heat dissipator and extends generally in the longitudinal direction.
