3. A pair of upper and lower shelves on which electronic devices are mounted are spaced apart from each other at an installation location such as a cabinet, and a forced air cooling unit is installed between the pair of shelves so as to be removable therefrom. The forced air cooling unit comprises a shielding housing having a substantially box shape and an air cooling board having a fan that ventilates the inside of the shielding housing through a forced air hole formed on the back surface of the shielding housing, The lower surface of the shielding housing is open to face a ventilation hole provided on the upper wall of the lower shelf of the pair of shelves,
The upper surface of the shielding case is a slope inclined from the rear side to the front side of the shielding case so as to face a ventilation hole formed in the lower wall of the upper shelf. Charger with structure.
