<P>PROBLEM TO BE SOLVED: To provide a camera device in which air-cooling effect of a camera can be improved without using electric power. <P>SOLUTION: The camera device 1 comprises: a camera 2; and a special sun-shield 4. The special sun-shield 4 comprises: a sun-shield section 5 covering the camera 2; and an air-cooling enhancement unit 6 arranged above the sun-shield section 5. A ventilation path 7 for air-cooling which has an intake port 8 at its bottom and an exhaust port 9 at its upper part is arranged between an outer periphery of the camera 2 and an inner peripheral surface of the sun-shield section 5. The air-cooling enhancement unit 6 comprises a cylindrical body 10 having a lower opening 13; and an upper opening 14. The lower opening 13 of the cylindrical body 10 is connected to the exhaust port 9 of the ventilation path 7. A material having a higher rate of solar heat absorption for absorbing the solar energy and converting it into thermal energy than the sun-shield section 5 is used for the material of the air-cooling enhancement unit 6. <P>COPYRIGHT: (C)2013,JPO&INPIT |
