Abstract
An electronic equipment has a heat-generating part therein. A housing accommodates component parts including the heat-generating part. A cooling-medium circulation system circulates a liquid internal cooling-medium between a heat-absorbing part and a heat-radiating part, the heat-absorbing part absorbing heat from the heat-generating part, the heat-radiating part radiating the heat absorbed by the heat-absorbing part. The heat-radiating part of the cooling-medium circulation system includes a first heat exchanger that performs heat exchange between a liquid external cooling-medium and the internal cooling-medium, the external cooling-medium being supplied from outside the electronic equipment, and a second heat exchanger that performs heat exchange between an air and said internal cooling-medium, the air being exhausted from the housing to outside.
