Abstract

A cooling structure of an electronic equipment includes substrate housing parts, an upstream side duct, a downstream side duct, an exhaust device and an air adjusting part. The substrate housing parts detachably house therein one or plurality of substrate units, and the downstream side duct allows the cooling air, which passed from the upstream side duct though the substrate housing part, to flow. The exhaust device is provided at an exhaust part to forcibly discharge air to the outside, thereby allowing the cooling air to flow to the substrate housing parts. The air adjusting part adjusts the volume for cooling air which flows to the downstream side duct.
