子機器筐体の冷却構造。[Scope of Claim for Utility Model Registration] A heat generating unit that is equipped with electronic components, etc. installed in an electronic device housing that has an outside air inlet that introduces outside air and an outlet that exhausts high-temperature air inside the housing. A cooling fan is provided at the top of the housing, and a box-shaped duct is provided inside the housing, having an air inlet at the bottom facing the cooling fan, and having an opening face facing the exhaust port of the housing. In the cooling structure for an electronic device housing, the inside of the housing is cooled by discharging high-temperature air generated from the heat generating unit from the exhaust port of the housing through a duct by a cooling fan, is partitioned by a partition plate along the air flow, one side of which is formed as a main duct with an inlet on the bottom, and the other side as a secondary duct with an inlet on the surface opposite to the opening surface. A ventilation hole is provided in the center of this partition plate, and an inclined guide member is provided to guide the air from the main duct sent through the ventilation hole toward the opening surface of the duct. Features a cooling structure for electronic device housings.
