Abstract:
1. A heat dissipation device, comprising: a box defining a first air passage, a second air passage, a first air intake, a second air intake, a plurality of first dissipation holes, and a plurality of second dissipation holes; a partitioning plate located inside the box between the first air passage and the second air passage, the first air intake and the first dissipation holes communicating with the first air passage, the second air intake and the second dissipation holes communicating with the second air passage; a cooling member fixed to the partitioning plate, and comprising a cold side facing the first air passage and a hot side facing the second air passage; a first heat sink received in the first air passage and abutting the cold side of the cooling member; a second heat sink received in the second air passage and abutting the hot side of the cooling member; and an air driven element mounted in the box, wherein the air driven element drives air to flow into the first air passage through the first air intake to be cooled by the first heat sink and expelled out of the box through the first dissipation holes; the air driven element also drives air to flow into the second air passage through the second air intake to absorb heat from the second heat sink and be expelled out of the box through the second dissipation holes.
