Abstract:
1. An electronic apparatus comprising: an enclosure in which an air outlet is formed; a circuit substrate built in the enclosure and mounted with circuit components including plural heat-producing components; and a heat radiating unit disposed in the enclosure and having a fan for blowing air, a heat radiating member in which heat radiation fins for transmitting heat to passing air are arranged, and a supporting member provided with a fan fixing section where the fan is fixed, the supporting member further having a heat-radiating-member biasing section disposed between the fan fixing section and the air outlet, the heat-radiating-member biasing section having an opening facing downward in the direction opposite to the circuit substrate to bias the heat radiating member toward the circuit substrate, the supporting member forming an air flow path in cooperation with the main unit, wherein the heat radiating member has an endothermic section that contacts a top surface of a first heat-producing component disposed on the circuit substrate so as to absorb heat from the first heat-producing component, and the supporting member has an endothermic arm that extends toward and contacts a top surface of a second heat-producing component on the circuit substrate so as to absorb heat from the second heat-producing component.
