By providing the partition plate 25 inside the casing 21, it is formed that the airflow generated by the fan unit 30 does not hit an electronic component that does not belong to the cooling target.

Further, when the partitioning plate 25 is not present inside the casing 21, the portion where the airflow from the fan unit 30 does not directly hit is also caused by the air being sucked by the airflow from the fan unit 30. airflow. In the industrial device 110 of the second embodiment, since the partition plate 25 is provided inside the casing 21, no other airflow is generated in the portion where the airflow from the fan unit 30 does not directly hit.

In the industrial machine 110 of the second embodiment, the cooling efficiency can be improved by limiting the cooling range of the fan unit 30. Further, since the dust can be restricted from entering the range in the industrial machine 110, the size of the filter 36 can be reduced.

In addition, when the industrial equipment 110 has a plurality of electronic components that become heat sources, the electronic components that generate heat during operation are concentrated in the cooling range of the fan unit 30, and electronic components that do not generate heat are concentrated. Since the fan unit 30 has a cooling range outside, the temperature of the electronic component that does not generate heat can be suppressed from rising.

Further, inside the casing 21, the portion separated from the fan unit 30 by the partition plate 25, that is, the cooling range of the fan 32, does not flow the airflow from the fan unit 30, and the fan unit 30 The other airflow generated by the outgoing airflow prevents the dust from adhering to the electronic components outside the cooling range of the fan unit 30.

The configuration shown in the above embodiments is an example of the present invention, and may be combined with other known techniques, and a part of the configuration may be omitted or changed without departing from the gist of the present invention.
