Electronic Apparatus Having a Heat-Radiating Unit for Radiating Heat of Heat-Generating Components

Abstract

An electronic apparatus includes a main unit, display unit and support unit. The main unit has a heat-receiving portion thermally connected to a heat-generating component. The display unit is separated from the main unit. The support unit is coupled to the main unit and display unit. The support unit includes a heat-radiating portion to cool a liquid coolant, and a reserve tank to temporarily store the liquid coolant. The liquid coolant absorbs heat produced by the heat-generating component and transferred by the heat-receiving portion. The liquid coolant is circulated between the heat-receiving portion and the heat-radiating portion.
