ABSTRACT:
A heat dissipator accessory for a notebook computer, which is concealed in an expansion slot of a notebook computer to effectively dissipate heat generated by the computer, is disclosed. The external heat dissipator for a notebook computer comprises a cooling module inserted into an expansion slot of the notebook computer. The cooling module includes a flat body having a connector electrically connected with a signal socket disposed in the expansion slot of the notebook, a cover disposed on the flat body and an air duct attached on the cover and mounted to the flat body. The flat body defines therein a chamber for receiving a fan and an air passage in communication with the chamber. The air passage has an air deflector transversely mounted at an end thereof for changing the direction of horizontal air flow. The cover defines a hole aligning with the fan chamber of the flat body and forming thereon a beveled portion corresponding to the air deflector. The beveled portion defines a plurality of openings for directing air from the flat body outside. The air duct defines therein a plurality of slits extending to an edge of the air duct and corresponding to the hole of the cover to allow air to be introduced to the chamber of the flat body via the hole of the cover.
