  • Patent number: 10420252
    Abstract: Provided is an electronic apparatus that makes it possible to improve a heat transfer property from a heat generating element to a heat storage material. The electronic apparatus is provided with a heat generating element and a heat storage device for storing heat generated by the heat generating element. The heat storage device includes a reaction chamber containing a heat storage material for absorbing the heat generated by the heat generating element. The reaction chamber is defined by a first surface, a second surface opposed to the first surface, and a plurality of side surfaces connecting the first surface with the second surface. In the reaction chamber, a thermal conductivity of a peripheral part is smaller than a thermal conductivity of a central part of the reaction chamber.

  • Publication number: 20150144295
    Abstract: There is provided an electronic apparatus having a novel means capable of suppressing temperature rise of a heat generating element. The electronic apparatus (20), which includes a heat generating element, is provided with a device (or a chemical heat pump) (10) comprising: a reaction chamber (1) containing a chemical heat storage material showing an endothermic reaction in response to heat emitted by the heat generating element (11); a condensation/evaporation chamber (3) for condensing or evaporating a condensable component produced from the endothermic reaction of the chemical heat storage material; and a communication part (5) communicating the reaction chamber (1) with the condensation/evaporation chamber (3) such that the condensable component is movable between the reaction chamber (1) and the condensation/evaporation chamber (3).
