Abstract:
1. A heat dissipation device mountable on a heat-generating component, comprising: a base in contact with the heat-generating component; a heat dissipating member on the base and having a cellular structure integrally formed therein; a fan mounted on the base adjacent to an end of the base close to the heat dissipating member and generating airflow to the heat dissipating member; and a covering body comprising a top wall in contact with a top of the heat dissipating member and a sidewall extending downwardly from an edge of the top wall and surrounding the heat dissipating member and the fan; wherein the cellular structure of the heat dissipating member comprises a plurality of elongated passages extending from an end of the heat dissipating member adjacent to the fan to another end of the base away from the fan; and wherein the base comprises a base plate defining an opening therein and a conductive envelope which is a plate-shaped vapor chamber received in the opening.
