Abstract
A high temperature camera apparatus having an elongated camera housing tube and an elongated camera support member, supporting a video camera at the interior end of the camera housing tube. A ceramic heat shield tube telescopically surrounds at least a portion of the camera, and preferably the portion of the camera housing tube which contains the camera. The exterior surface of the camera housing tube is plated and polished to provide a highly reflective surface. The ceramic heat shield is spaced in position around the camera housing tube by a plurality of spacers projecting outwardly form the outer surface of the camera housing tube. A liquid coolant jacket may also be formed on radially opposite sides of the camera housing tube.
Claims13
A high temperature camera apparatus including a video camera for viewing the interior of a high temperature chamber through an opening in a wall of the chamber, the apparatus comprising:
- (a) an elongated camera housing tube forming an interior passageway, for extending through the opening and having an exterior end for mounting relatively nearer the exterior of the chamber wall and an interior end for mounting near the interior of the chamber wall;
- (b) a removable, elongated camera support member extending into and along the camera housing tube and having the camera mounted near an interior end of the support member and extending to the exterior end, the support member supporting the camera at the interior end of the camera housing tube;
- (c) a ceramic heat shield tube telescopically surrounding and spaced radially from the camera, the ceramic heat shield extending an entire axial length of the camera and surrounding at least a portion of the camera support member;
- (d) an air inlet manifold including an air inlet in fluid communication with the interior passageway of the camera housing tube for transporting cooling fluid along the interior passageway and cooling the camera.
