PROBLEM TO BE SOLVED: To improve cooling efficiency by natural air cooling at low cost by integrally installing a rib-shaped member like a plate, a curved surface and others to control the air flow inside appliances in a desired direction on an outer surface of a built-in box to be incorporated inside various electronic equipment. SOLUTION: A CRT 5 and a speaker box 6 are installed at exterior parts 2 of a television at a front surface, and the positions of heat generating parts 4 are on a substrate 3 come approximately the rear of the box 6. The air flows inside completed appliances can be controlled by integrally providing the rib- shaped wind-direction panel 7 like a plate, with the curve on the upper side of the heat generating parts 4 at the rear of the box 6. Therefore, the air flow for emitting heat which is generated inside the appliances, especially in the case of the natural air cooling to the outside becomes changeable with only the box 6. Thus, the ringing of the box is reduced by increasing the rigidity of the box 6, efficiency of the natural air cooling enhanced at the same time, and increase in cost is suppressed.
