Claims

[Scope of Claim for Utility Model Registration] 1. A plurality of panels in a housing that has an openable door on the opening surface, an intake port for taking in outside air for cooling on the bottom surface, and an exhaust port for discharging hot air on the upper back surface. A storage case consisting of an array of circuit boards is stored for a predetermined period of time.
A plurality of circuit boards are provided in the storage case to stack them vertically for storage, and a cooling fan is provided between the storage cases and at the upper end of the case, and the plurality of circuit boards in the storage case are pressed to the back of the case. and a holding member for holding the outside air inside the case while preventing movement due to vibrations, etc.; In the cooling structure, a separation shielding plate is provided inside the intake port on the lower surface of the casing to divide the taken in outside air into two in the front and back direction, and the outside air separated by this separation and incoming air is taken in, A cavity is provided on almost the entire inside of the door to feed air from the opening to the bottom side of each of the upper storage cases, and between each of the plurality of storage cases, the ventilation between each of the storage cases is partitioned to A partition plate that guides air from the case to the back side of the upper storage case, and a cooling fan at the rear of the upper surface of the lower storage case so as to be on the bottom side of this partition plate, are installed to draw outside air to each storage case. A cooling structure for an electronic device case, characterized in that it is configured to cool independently by feeding the air. 2. The electronic device casing according to item 1, wherein the holding member is attached to the inside of the cavity of the door corresponding to the upper and lower ends of the circuit board stored in the storage case when the door is closed. cooling structure.
