Claims

[Scope of utility model registration request]

The airtight inner casing has multiple shelves inside and supports and stores electronic devices, etc., and heat dissipation fins are installed on the outside and inside of the case, using the inner body wall as a common wall plate for the duct. Internal ventilation ducts equipped with heat absorbing fins are placed adjacent to each other to form an external ventilation duct, the external ventilation duct is configured to pass outside air, and the internal ventilation duct is equipped with a ventilator for agitating and circulating the heated air inside the inner cylinder body. A heat dissipation structure characterized in that the hot air is controlled to flow in opposite directions to each duct and is connected to each duct, and the inner body wall surface, which is a common wall plate of both the ducts, maintains a heat exchange function. Closed housing with.
