Claim Text:
1. An ignition protection housing assembly, comprising: an external casing having a plurality of solid walls that define an internal compartment having an open side, and a cover disposed along the open side to enclose the internal compartment, wherein an air gap is defined along an interface between the cover and the walls of the casing, the air gap being configured to have a dimension that inhibits ignition flashover between the internal compartment and the environment, a temperature sensor thermally and rigidly connected to one of the plurality of walls disposed to measure, and provide information indicative of, a temperature of the casing wall to which the temperature sensor is connected to a control device; and a temperature altering device thermally connected to one of the plurality of walls and operating to change a temperature of the casing by conducting heat to or away from the plurality of walls in response to commands provided by the control device; wherein the control device selectively activates and deactivates the temperature altering device for heating or cooling the casing by conductive heat transfer in response to temperatures determined by the temperature sensor.
