Patent ID: 8000102

Claim:
A housing apparatus for electrostatic precipitator voltage control circuitry components, comprising: a hermetically sealable high-voltage component tank portion filled with a liquid coolant and containing at least a high-voltage transformer-rectifier component set submerged within the liquid coolant, a removable cover plate on a top side of the tank portion, a high-voltage output terminal insulating bushing mounted through the removable cover plate at the top side of the tank portion, the tank portion having at least one panel-type radiator structure mounted on an outside wall of the tank portion for circulating and cooling the liquid coolant, wherein the liquid coolant contained within the tank portion circulates through the radiator structure via convection currents when heated by the submerged high-voltage transformer-rectifier component set; a liquid-free air-cooled high-voltage component compartment sharing a common sidewall with the tank portion, one or more high-voltage conductor pass-through insulating bushings mounted through the common sidewall, and a high-voltage spiral-wound capacitor filter network contained in the liquid-free air-cooled high-voltage component compartment.
