Apparatus and arrangement for housing voltage conditioning and filtering circuitry components for an electrostatic precipitator

A unitary-enclosure housing apparatus and arrangement for protecting and cooling the high voltage electronic conditioning and filtering circuitry components used for providing a high-voltage waveform to an electrostatic precipitator device includes a hermetically sealed dielectric liquid coolant filled tank/housing having one or more side-mounted hollow-panel type radiator structures for dissipating heat from the coolant. The disclosed unitary-enclosure housing apparatus and the particular arrangement of the internal electronic components results in a relatively external small footprint while containing both the transformer-rectifier (TR) set and high-voltage resistor-capacitor (R-C) filter components associated with a high-voltage electrostatic precipitator device in a single unitary package. The housing apparatus is outfitted with a removable top cover plate and access panel for providing easy access to the TR set and R-C filter components. A coolant drain spigot is also provided on the housing for simplifying the draining and replacement of coolant liquid.
