Abstract: An electronic apparatus includes a housing that includes an air inlet, and an air-intake duct section provided to supply air to the air inlet, and a filter housing that houses a filter provided to cover the air inlet, and moves toward the air-intake duct section in a thickness direction of the filter housing, to shift from a closed state in which the filter covers the air inlet to an open state in which the air inlet is uncovered.

Abstract: A cooling apparatus includes: a plurality of evaporation chambers in which a refrigerant is accommodated; a steam path including a plurality of steam path branch portions which extend from the plurality of evaporation chambers, respectively, and a steam path body portion in which the plurality of steam path branch portions join with each other; a condensing chamber coupled to the plurality of evaporation chambers through the steam path; a liquid path including a liquid path body portion which extends from the condensing chamber, and a plurality of liquid path branch portions, which are branched from the liquid path body portion to be coupled to the plurality of evaporation chambers, respectively; and a check valve installed in the steam path and suppresses a reverse flow of the refrigerant from one evaporation chamber to another evaporation chamber among the plurality of evaporation chambers.

Abstract: An electronic device includes: a plurality of board units, each configured to include a board and a heat generation part installed on the board, the plurality of board units configured to be arranged in an axial direction perpendicular to the board; and a radiating structure configured to thermally connect with the heat generation part, and include a plurality of duct formation portions provided in the plurality of board units, the plurality of duct formation portions being arranged in the axial direction perpendicular to the board so that an air duct extending in an axial direction perpendicular to each board is formed.
