Abstract

An electronic apparatus has a water-cooling system suited for a construction having compact, thin design. In the electronic apparatus, a water-cooling jacket is thermally connected to a heat-generating element, a heat-dissipating pipe is thermally connected to a heat-dissipating metal sheet provided at a rear panel of a display case, and a cooling medium liquid is circulated between the water-cooling jacket and the heat-dissipating pipe by a liquid-moving device. A necessary and sufficient circulating flow rate and a necessary discharge pressure are determined by the relation between the upper limit temperature of the heat-generating element and the limit amount of heat dissipation from the surface of the housing. With this structure, heat occurring in the heat-generating element can be dissipated from the rear surface of the display case due to the necessary and sufficient liquid-circulating flow rate.
