Abstract:
1. An electronic equipment having a heat-generating part therein, the electronic equipment comprising: a housing accommodating component parts including the heat-generating part; and a cooling-medium circulation system for circulating a liquid internal cooling-medium between a heat-absorbing part and a heat-radiating part, the heat-absorbing part absorbing heat from said heat-generating part, the heat-radiating part radiating the heat absorbed by the heat-absorbing part, wherein said heat-radiating part of said cooling-medium circulation system includes: a first heat exchanger, which is a medium exchanging heat between a high temperature fluid and a low temperature fluid, the first heat exchanger performing heat exchange between a liquid external cooling-medium and said internal cooling-medium, the external cooling-medium being supplied from outside said electronic equipment; a second heat exchanger, which is a medium exchanging heat between a high temperature fluid and a low temperature fluid, the second heat exchanger performing heat exchange between an air and said internal cooling-medium, the air being exhausted from said housing to outside; and said first heat exchanger is separate from said second heat exchanger so that the cooling medium discharged from said first heat exchanger is supplied to said second heat exchanger.
