Mounting device and an air flow control device

A mounting device comprising:

• a housing in which accommodation portions accommodating a plurality of electronic units, respectively, are arranged in parallel;
• a fan configured to send cooling air to the plurality of electronic units;
• and
• a plurality of air flow control devices, provided in an airflow path for the cooling air in accommodation portions, configured to control flow of the cooling air,
• wherein
• each air flow control device includes:
• a first panel having at least one opening for the cooling air to pass therethrough;
• a second panel, slidably provided to overlap the first panel, configured to open or close the opening of the first panel;
• a driving force generation mechanism provided in the airflow path configured to cool air and have an air receiving member for receiving an air pressure of the cooling air, the driving force generation mechanism configured to generate a driving force corresponding to the air pressure received by the air receiving member;
• and
• a link mechanism, coupled to the driving force generation mechanism and the second panel, configured to receive the driving force generated by the driving force generation mechanism and provide a driving force that slides the second panel.
