Abstract
PURPOSE:To allow a certain, optimal control of cooling air with a simple constitution by controlling with upper and lower bars on a link mechanism the opening and closing operation of vanes of a vane mechanism arranged between package guides. CONSTITUTION:When an electronic circuit package 1 is not inserted into a package guide, vanes 6 of a vane mechanism 3 are closed with a lower bar 8 being pulled by a spring 16, whereby the flow of cooling air is blocked. Upon insertion of the package 1, a guide pin 5 thereof presses a connecting part 15 of an upper bar 7 to rotate the vanes 6 to an opening position, whereby cooling air is introduced to the package 1. At this point, cooling air flow volume is adjusted by rotating angle of the vanes 6 being changed in function of the mounting position of the pin 5. According to the constitution, cooling air can be controlled optimally without fail with a simple constitution which requires no dummy module or cover plate.
