FIG. 1 is a perspective view showing a configuration example of an embodiment of an electronic apparatus according to the present invention. As shown in FIG. 1, the unit 1 is provided with a front slit 5 for securing an air flow path, and has a built-in fan (FAN) 2 for forcibly cooling the components mounted on the substrate 4. . An input / output connector 8 for power supply and signal input / output is mounted on the back of the unit 1. In addition, the substrate 4
The unit 1 is connected via a vertical / horizontal conversion relay board 6 for converting the mounting direction (horizontal direction) of the board 4 to the vertical direction.
Is connected to a power supply backboard 7 which is arranged so as to be detachable in a direction perpendicular to the direction in which air flows.

Next, the operation will be described. FAN
2 starts the rotation operation after the start switch 3 of the unit 1 is turned on, and starts to draw air from the front slit 5 of the unit 1. Thus, forced air cooling of the heat-generating component mounted on the board 4 is started.

On the other hand, each voltage, current and signal generated by the components mounted on the unit 1
Is supplied to the input / output connector 8 of the vertical / horizontal conversion relay board 6 mounted in parallel with the plane including the board 4 of the unit 1 via the input / output connector 8 provided on the back surface of the unit 1.

The convection of the air after the forced air cooling is
2, the air is forcibly exhausted from the back of the unit 1. At this time, since the vertical / horizontal conversion relay substrate 6 is mounted so as to be parallel to the substrate 4 of the unit 1, the convection of the exhausted air is blocked. Exhausted from the back without being
Ventilation is provided.

As described above, in the above embodiment,
In the case where forced air cooling is performed by the FAN 2 mounted on the rear surface or the front surface of the unit 1, the power supply backboard 7 mounted close to the rear surface and connected to another unit as in the conventional device shown in FIG. Does not exist, the exhaust passage is not obstructed from the front to the back of the device, and forced air cooling can be efficiently performed. For this reason,
It is possible to make it difficult for heat to remain inside the unit 1 and in the vicinity thereof, and it is possible to perform almost complete ventilation. Further, the unit 1 can be easily attached to and detached from the vertical / horizontal conversion relay board 6.

As described above, when the air-cooling structure of the electronic device is the same as that of the above-described embodiment, the air-cooling structure of the fan can be reduced when the unit on which the fan for forced air-cooling is mounted is mounted on the housing. Can be prevented from obstructing the exhaust passage. Also, the unit can be easily attached and detached.

In the above embodiment, the case where the present invention is applied to a unit mounted on an exchange or the like has been described. However, the present invention can be applied to other electronic devices requiring cooling.
