TEMPERATURE RISE SUPPRESSING DEVICE OF VEHICULAR OVERHEAD MODULE

摘要

PROBLEM TO BE SOLVED: To provide a temperature rise suppressing device of a vehicular overhead module capable of allowing equipment of low heat resistance such as communication equipment by suppressing the temperature rise of an overhead module when it is left under the scorching sun. SOLUTION: A blower 3 utilizing the tornado air current is integrated with an overhead module body 1 mounted on the inner side of a roof outer plate B1 of a vehicle. The blower 3 has an inlet 305 opened in a vehicular ceiling part and an outlet 306 therearound. The blow-out air flow A2 discharged from the outlet 306 works as an air curtain, and generates the rising suction air flow A1 while spirally rotating toward the inlet 305 in a center part. Low-temperature air below the vehicle is sucked by the tornado air current to suppress the temperature rise of a ventilation duct part 104 with an electronic equipment 2 mounted thereon.
