BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor housing which incorporates electronic equipment and is installed outdoors.

[0002]

2. Description of the Related Art This outdoor housing is used, for example, in a disaster prevention radio system, as a receiving station that receives and broadcasts radio waves from a base, or a relay station that transmits radio waves received from a base to other receiving stations. In this case, the outdoor housing is often installed on a high place such as a telephone pole where radio waves can pass well.

As shown in FIG. 13, an outdoor housing 31 includes a main body 32 and a lid 33 for opening and closing the front of the main body 32, for example.
And an electronic device 34 and a battery 35 are built in.

[0004] In the outdoor housing 31, the space between the main body 32 and the lid 33 is sealed by packing (not shown), and the closed lid 33 is locked. In addition, since the outdoor housing 31 is used as a receiving station or a relay station, once the power is turned on, the lid 33 is not opened or the power is not turned off for a long time except for maintenance and inspection or when there is a failure. used.

[0005] Since the outdoor housing 31 is sealed for a long period of time, the air around the electronic equipment 34 and the like is warmed by heat generated from the electronic equipment 34 and the like, and the hot air accumulates in the upper portion inside the main body 32.

Since the temperature inside the main body 32 rises as described above,
This may cause a failure of the electronic device 34 or shorten its life.

Further, when the outdoor housing 31 is installed in a cold region, a temperature difference between the inside and the outside of the outdoor housing 31 increases, and water drops are generated on the inner top wall, and the outdoor housing 31 falls on the electronic device 34 or the like. , Causing a failure.

As a countermeasure against the rise in the internal temperature of the outdoor housing, an air-cooling structure of the outdoor housing disclosed in Japanese Patent Application Laid-Open No. 8-116190 has been conventionally known.

In this air-cooled structure, the air around the electronic equipment and the like becomes an ascending airflow due to the heat of the electronic equipment and the like, and after colliding with the top wall, becomes a descending airflow along the side wall.
The heat is emitted from the side wall while being guided by the convection guide plate so as not to return to the electronic device or the like.

[0010]

However, in the air cooling structure described in Japanese Patent Application Laid-Open No. Hei 8-116190, the heat radiation is slow because the convection inside the housing is used.
There is a problem that the air cooling performance is limited.

An object of the present invention is to provide an outdoor housing having an air-cooling structure having a high air-cooling performance for quickly releasing heat.
