体保管器６が設置されている。Conventionally, this type of casing has been used, for example, in collective optical disk devices. FIG. 2 is a longitudinal sectional view of this collective optical disk device. To explain this with reference to the figure, the inside of the flute body 1 is separated into a power supply chamber 2 and a storage chamber 3 by a partition wall 11. In the power supply room 2, there are devices 4a to 4 for power supply, etc.
A cooling fan 8 is provided in the upper part of the power supply room 2, and an opening 1b is provided in the upper surface of the housing 1. The storage chamber 3 consists of an electronic device storage section at the bottom and a medium storage section at the top. Optical disk units 5 each consisting of two decks 5& and two electronic devices 5b are installed in the electronic device storage sections. A medium storage device 6 containing an optical disk medium 7 is installed in the storage section.

対流するかまたは収納室３の上部に澱むことになる。When this collective optical disk device is powered on and starts operating, the power supply devices 4a to 4C in the power supply room 2 generate heat. The surrounding air heated by this generation moves to the upper part of the power supply room 2 as shown by the arrow, and is exhausted to the outside of the housing through the opening 1b provided in the upper part of the housing 1 by the cooling fan 8. Ru. On the other hand, in the storage room 3, the upper and lower 2
The air heated by the heat generated by the electronic device 5b in the optical disk unit 5 of the stand moves in the direction of the arrow and convects around the medium storage means 6 and the optical disk medium 7 in the upper part of the storage chamber 3. It will accumulate in the upper part of the storage chamber 3.
上述した従来の筐体の冷却構造では、収納室３内の熱は
、隔壁によって電源室と分離されているため、筐体外へ
排出されることがないから、媒体収納部の温度を上昇さ
せるという不都合があった。In the conventional case cooling structure described above, the heat inside the storage chamber 3 is separated from the power supply room by a partition wall, so it is not discharged outside the case, which increases the temperature of the medium storage section. There was an inconvenience.
本発明の電子機器筐体の冷却構造は、隔壁で左右に分離

６を設置し、中に光デイスク媒体７が保管されている。FIG. 1 is a longitudinal cross-sectional view of a collective optical disk device showing an embodiment of the cooling structure for an electronic device housing according to the present invention. The inside of the casing 1 is divided into a power supply room 2 and a storage room 3 on the left and right sides by a partition wall 1a.The power supply room 2 stores equipment 4&~4c for power supply, and the upper part of the power supply room 2 contains A cooling fan 8 is provided, and an opening 1b is provided on the top surface of the housing 1. The storage chamber 3 is partitioned by a partition member 1d into a lower electronic device storage section and an upper medium storage section. Two optical disk units 5, upper and lower, are installed in the electronic device storage section at the bottom.
This optical disk unit 5 includes a deck 5o and an electronic device 5b.
It is made up of. A medium storage device 6 is installed in the upper medium storage section, and an optical disk medium 7 is stored therein.
