Broadcast vans are often used in harsh external environments, and in summer the temperature inside the car sometimes rises to about 45 ° C. At such a high temperature, a flow of cool air as shown in FIG. 8 can be expected in an ideal state by simply blowing out cool air from the upper portion of the vehicle body 11 as in a conventional cooling device. Under the environment, the flow of the cold air becomes unstable and does not reach sufficiently below the inside of the vehicle main body 11, so that the electronic devices installed particularly below the shelves cannot be sufficiently cooled.

As described above, since the electronic unit 14b, which is made of an integrated circuit and is greatly affected by heat, is placed below the shelf 15, the upper and lower regions of the shelf 15 are secured in order to ensure operational reliability. It is desired that good cooling be performed over the entire area. In the future, as more sophisticated electronic units are developed and installed in the future, it is considered that in vehicles equipped with electronic devices such as broadcast broadcast vehicles, measures against heat will be a major technical problem.

To cope with this heat problem, a large air conditioner having a large capacity / capacity may be used. , Height), driving operation problems (vehicle length), etc., and restrictions on the internal space, etc., it is not easy to install a large-sized air conditioner.
