Abstract
Projection television display tube comprising an evacuated envelope having a display window provided on its inside with a display screen, a transparent second window which is disposed in front of said display window on its outside, and a transparent coolant flowing through the space between the display window and the second window, said coolant conveying the heat taken up at the display window through a cooling member to the atmosphere. The coolant is also in thermally conducting contact with a latent heat accumulator, so that an effective cooling is obtained even at peak loads of more than 40 W, and without external pipes.
