PURPOSE:To enable cooling of an indoor air by a heat generating body and to prevent a bad influence from being exercised on a temperature detecting sensor, by a method wherein, in a device having the heat generating body mounted in the proximity of said sensor, a cooling air path is formed in the heat generating body. CONSTITUTION:One end of a suction duct 2 is connected to an air inlet 2 in an instrument panel 1, and a suction cylinder 31 having a suction fan 3 is joined to the other end thereof. An indoor temperature detecting sensor 5 is located in the air inlet 2, and an audio unit, acting as a heat generating body, is installed in the proximity of the sensor 5. In which case, the inner space of said unit 6 acts as a cooling air path 61, the front end thereof is formed into an indoor opening 62, and the rear end is linked to the suction duct 4 through the medium of a branch lpipe 4. This prevents heating of the unit 6 by the passage of an indoor air through the inner space of the unit 6 through the medium of the branch pipe 41 to achieve a required purpose. |
