Patent ID: 8096861

Claim:
A housing apparatus for a heat generating device, comprising: a housing which has a height, a width, and a depth, and which includes a plurality of sidewalls arranged in a lateral direction along the width to separate from each other, and a plurality of shelf members placed at a plurality of positions along the sidewalls between the sidewalls to support a plurality of devices including at least one heat generating device, the plurality of positions being arranged in a height direction along the height, and each sidewall having a plurality of ventilation openings arranged in the height direction to correspond to the devices held by the shelf members; a duct member which is provided on at least one outermost sidewall of the sidewalls of the housing, and which corresponds to at least two ventilation openings located adjacent to each other in the height direction in the at least one outermost sidewall, the duct member including an airflow guide plate providing at least two adjacent airflow guide paths corresponding to the at least two adjacent ventilation openings, the at least two adjacent airflow guide paths communicating with the at least two adjacent ventilation openings respectively; and an airflow producing unit which is provided on the duct member and which includes at least two airflow producing devices performing one of supplying outside air into the inside of the housing and evacuating the inside air from the housing through the at least two adjacent ventilation openings corresponding thereto; wherein the at least two airflow producing devices of the airflow producing unit are arranged in the back and forth direction; each of the at least two airflow producing devices arranged in the back and forth direction faces the at least two adjacent ventilation openings located adjacent to each other in the height direction and corresponding to the at least two airflow producing devices through the duct member, the airflow guide plate being located between the at least two airflow producing devices and the at least two adjacent ventilation openings located adjacent to each other in the height direction; and each airflow producing device performs one of supplying outside air to the inside of the housing and evacuating the inside air from the housing, through each airflow guide path corresponding to the respective airflow producing device and through each of the at least two adjacent ventilation openings corresponding to the respective airflow producing device wherein when evacuating the inside air from the housing, the outlets of the at least two adjacent airflow guide paths are arranged in a back and forth direction along the depth.
