Abstract:
To provide an electronic equipment capable of preventing temperature raise of a casing by improving heat radiation ability by means of natural air cooling without increasing the cost.SOLUTION: The electronic equipment comprises: a casing 9 which is formed by sandwiching both ends of a case 3 with a first end face plate 1 and a second end face plate 2; circuit boards 41, 42 on which heating components 31, 32 are mounted; and outer fins 11, 12, 13 protruding out of the casing 9. In a space of the casing 9 in a portion excluding a circuit board 41 on which the heating component 31 is mounted, an inner fin 14 is formed in which the inner side of the first end face plate 1 protrudes. With this, the inner fin 14 absorbs heat and the heat is radiated via an outer fin 11 of the first end face plate 1 to prevent temperature raise of the casing 9.SELECTED DRAWING: Figure 4
