Heat sinking means and method for projection television CRTs |
摘要 |
Heat sink means for a projection television cathode ray picture are disclosed. The tube has a face plate on the inner surface of which is deposited a cathodoluminescent screen for forming a television image. The face plate develops an undesirably high temperature during operation resulting in cracking. The heat sink means according to the invention comprises a heat-conductive panel, which may be a metallic plate, larger in area than the face panel. The panel has a window for passing the television image. The panel is in intimate contact with the face plate for conducting heat from the face plate and inhibiting thermal cracking.
