<p>PURPOSE:To improve heat radiation and prevent heating of receiver apparatus by using a transparent film bag which is filled with cooling liquid while has a space partly without cooling liquid, wherein the liquid part are connected to the space part by a bypass. CONSTITUTION:A video projection part 51 contains a transparent film bag 53 filled wit cooling liquid 52, by the use of a frame 54. A CRT 55 and a lens 56 are attached to the frame 54 through transparent film bag 53. The lower part of the transparent film 53 is a part 57 where cooling liquid 52 is filled and sealed and the upper part is a pressure absorbing part 58 to absorb pressure from the part 57. The frame 54 which contains the transparent film bag 53 is formed by metal such as aluminum die casting, etc. Heat generated at the CRT 55 therefore, is once absorbed to the cooling liquid 52, and then radiated from the frame 54 through the transparent film bag 53, after the expanded and vaporized cooling liquid 52 goes through the bypass part to the upper side of the transparent film bag 53. Heat radiation is thus improved.</p> |
