Abstract
An improved structure for cooling a cathode ray tube apparatus for projecting color images includes a cooling medium contained in a space defined by a front panel of the cathode ray tube, a front panel or lens, and a metallic frame for transferring heat from the tube to the frame. An improvement includes an air or expansion chamber communicating with the defined cooling medium space to permit expansion of the heated cooling medium into the chamber, while preserving the distance between the front panel of the tube and the lens.
