<p>A structure for cooling a cathode ray tube apparatus (10) for projecting colour images includes a cooling medium (28) contained in a space (17) defined by a front panel (11A) of the cathode ray tube (11), an outer front panel or lens (27), and a metallic frame (12), for transferring heat from the cathode ray tube (11) to the frame (12). An air or expansion chamber (29) communicates with the cooling medium space (17) to permit expansion of the heated cooling medium (28) into the expansion chamber (29), while preserving the distance between the front panel (11A) of the cathode ray tube (11) and the outer front panel or lens (27).</p> |
