  • the fan unit 30 is arranged above the object to be cooled, if the filter 36 is made small, the airflow flowing through the industrial equipment 100 becomes thin and the cooling performance deteriorates, but the industrial equipment according to the first embodiment. Since the airflow 100 blows the airflow to the cooling target from below, the cooling performance is not impaired even if the filter 36 is made small.
  • the industrial device 100 blows an airflow from below to the cooling target, even when the electronic component that generates heat is the cooling target, the fan 32 is not blown by the heat generated by the electronic component, The durability of the fan 32 can be improved.

  • FIG. FIG. 14 is a perspective view showing a configuration of an industrial device according to Embodiment 2 of the present invention.
  • a part of the industrial device 110 is not shown for easy understanding of the structure of the industrial device 110.
  • the industrial device 110 according to the second embodiment is different from the industrial device 100 according to the first embodiment in that a partition plate 25 that restricts the reach of the airflow is provided inside the housing 21.
  • the partition plate 25 is disposed on the side surface of the fan unit storage unit 22.
  • the partition plate 25 is positioned on the left and right of the fan unit storage unit 22.
  • the partition plates 25 arranged on the side surface of the fan unit storage unit 22 are positioned in front of and behind the fan unit storage unit 22.
  • the partition plate 25 is a planar member.
  • electronic parts to be cooled are mounted on a portion sandwiched between the partition plates 25. That is, in the industrial device 110, electronic components that generate heat are arranged on the same side as the fan unit 30 with the partition plate 25 as a boundary. Since the partition plate 25 is provided inside the housing 21, the air current generated by the fan unit 30 is not applied to electronic components that are not to be cooled.
  • the industrial device 110 according to Embodiment 2 can improve the cooling efficiency by limiting the cooling range by the fan unit 30. In addition, since the range in which dust enters the industrial device 110 can be limited, the size of the filter 36 can be reduced.
  • the electronic components that generate heat during operation are collected in the cooling range by the fan unit 30, and the electronic components that do not generate heat are cooled by the fan unit 30.
  • the fan unit 30 By concentrating out of the range, it is possible to suppress an increase in the temperature of the electronic component that does not generate heat.
  • the airflow from the fan unit 30 and the airflow from the fan unit 30 are generated outside the cooling range of the fan 32 by the part separated from the fan unit 30 by the partition plate 25. Since no other airflow is allowed to pass through, it is possible to prevent dust from adhering to electronic components outside the cooling range by the fan unit 30.
  • the configuration described in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and can be combined with other configurations without departing from the gist of the present invention. It is also possible to omit or change the part.
