Claims

[Scope of utility model registration request]

The first surface is provided with an opening, and the first surface is provided with an opening.
A second surface, which is perpendicular to the surface, is provided with an air plenum surrounded by an inner wall and an outer wall, and the inner wall is provided with a plurality of ventilation holes, and a colloid, which is perpendicular to the first surface, is provided. A box-shaped chassis is provided with a square hole in the outer wall at a position opposite to the ventilation hole provided in the inner wall, and a flange portion is slightly larger than the square hole;
and a guide plate that is installed perpendicularly to the flange portion and is provided with a large number of round holes for adjusting air volume, and further includes a guide plate that is positioned within the air plenum, and a guide plate that is installed perpendicularly to the flange portion, and is arranged such that the guide plate is located within the air plenum. Electronic circuit components are mounted on both outer surfaces of an air volume distribution plate attached to the chassis so as to be covered from the outside by the flange portion, and a rectangular plate-shaped heat exchanger with an internal ventilation passage. It is made up of a printed circuit board glued together, one side of which is provided with a cooling air inlet and is inserted into the U-shaped groove, and an electronic circuit module housed in the chassis. An electronic device characterized by:
