1. A cooling structure of an electronic equipment needing forced-air-cooling comprising:

  • at least one substrate housing part detachably housing therein one or plurality of substrate units;

    an upstream side duct provided at the upstream side of air for cooling which is allowed to flow to said substrate housing part;

    a downstream side duct for allowing the air for cooling which passed from said upstream side duct through said substrate housing part to flow;

    exhaust means provided at an exhaust part for allowing said downstream side duct to open to an outside air to forcibly discharge air in said substrate housing part to the outside air, thereby allowing the air for cooling to flow to said substrate housing part; and

    air adjusting means for adjusting the air for cooling which passes from said upstream side duct to said downstream side duct through said substrate housing part, said air adjusting means having a plurality of adjustable air openings in opening areas corresponding to each of said substrate units in said substrate housing part,wherein said air adjusting means is installed in either or both of a first boundary part where said substrate housing part and said downstream side duct contact each other or a second boundary part where said substrate housing part and said upstream side duct contact each other, thereby adjusting the air for cooling to a volume of air corresponding to said substrate units installed in said substrate housing part.
