The present protective/cooling system includes a housing which contains electronic circuitry and optics for a vision system typically operating in a high temperature, turbulent dust and debris environment. The vision system is located in an inner chamber which is sealed from the surrounding harsh environment. A cooling fluid flows through spiral passages around the inner chamber for drawing heat from the contained vision system. The cooling fluid exits across an optical interface in a spiral flow pattern which enhances both the cleaning ability and the cooling efficiency of the cooling system.
