PURPOSE:To further improve heat radiation effect by providing a liquid tight extending space, into which a transparent liquid coolant flows, between a protruded part provided at least at the upper edge of a transparent panel and a metal frame of said transparent panel. CONSTITUTION:The internal edge of frame part 3A of metal frame 3 is immersed into liquid coolant 6 which is provided in contact with the front panel 1a of a cathode ray tube body 1, assuring direct contact between the edge and coolant. Moreover, a space 5A is provided between the protruded part 2C of transparent panel 2 and particularly the protruded part 3C of metal frame 3 so that the liquid coolant can also flows into such space. Thereby, the contact area between metal frame 3 and coolant 6 increases and the contact area between transparent panel 2 and coolant 6 also increases, resulting in increase of heat radiating area and heat absorbing area formed by the metal frame 3 and the front panel 2. Since the protruded part 2C is provided at least at the upper edge of panel 2, the heat on the upper part of coolant 6 at a high temperature which is raised by the heat generated from the cathode ray tube body 1 is radiated effectively. |
