Abstract: An auxiliary cooling device for a notebook computer, the device is for placing beneath the notebook computer and is comprised of: a base with a receiving space therein and at least a heat-sinking hole in communication with outside; at least a fan mounted in the base, and being communicated with outside via the heat-sinking hole; and an upper lid having an upper panel provided with an air-venting hole. When the notebook computer is placed on the upper lid, heat generated by operating the notebook computer is led into the receiving space of the base, and is dissipated by running the fan, thus temperature of the notebook computer is lowered to afford long-time operation of the notebook computer without generating higher temperature. The device is suitable to help heat sinking of notebook computers.
