Electronic device including radiation structure

An electronic device comprising:

• a housing including a first plate facing a first direction, a second plate facing a second direction that is opposite to the first direction, and side members configured to surround a space between the first plate and the second plate;
• a bracket disposed in the space of the housing;
• a first graphite sheet disposed between the bracket and the first plate, the first graphite sheet being supported by the bracket and thermally combined with the first plate;
• a circuit board disposed between the bracket and the second plate in the space of the housing and including at least one heat generation element;
• a first vapor chamber configured to receive and diffuse a first portion of heat discharged from the at least one heat generation element, the first vapor chamber disposed at least some of a space between the bracket and the circuit board;
• a heat sink configured to receive and absorb a second portion of the discharged heat from the at least one heat generation element, the heat sink disposed in at least some of a space between the circuit board and the second plate;
• and
• a fan configured to blow air so that the absorbed second portion of the heat by the heat sink is forcibly moved toward an outside of the electronic device.
