摘要： A method and apparatus for cooling a cathode ray tube in a projection television receiver including a lens assembly for focusing images formed by the cathode ray tube. A cooling chamber is arranged in front of the cathode ray tube and behind the lens assembly in thermal contact with the face of the cathode ray tube through which the images are projected. This cooling chamber is then filled with an optically clear substantially waterless liquid consisting of an isoparaffinic solvent which is distributed under the trademark ISOPAR V.
