Abstract:
1. An electronic device comprising: an enclosure having a side wall in which vent holes are formed; a first heat generator stored in the enclosure; a second heat generator stored in the enclosure; a first radiator disposed adjacent to the vent holes; a second radiator disposed adjacent to the first radiator; a first heat receiver thermally connected to the first heat generator; a second heat receiver thermally connected to the second heat generator; a first heat pipe having one end thermally connected to the first heat receiver, and the other end thermally connected to the first radiator; a second heat pipe having one end thermally connected to the second heat receiver, and the other end thermally connected to the second radiator; a fan disposed adjacent to the second radiator to generate cooling air toward the first and the second radiators; and a seal plate that seals a first gap formed between the first radiator and the side wall in which the vent holes are formed, and a second gap formed between the first radiator and the second radiator, wherein the second radiator is disposed between the first radiator and the fan, the cooling air flows from the fan to the vent holes serially through the second radiator and the first radiator, the seal plate is formed of two side seal plates that seal both sides of the first gap and the second gap, and a top seal plate that seal an upper portion of the first gap and the second gap, an edge portion of each of the side seal plates is formed to be connected to at least one of a bottom wall and the side wall having the vent holes formed therein of the enclosure so as to be integrally formed into a rib structure, and a recess portion is formed in the bottom wall of the enclosure for accommodating the fan, the first radiator, and the second radiator.
