Abstract: A heat dissipating protective cover for electronic devices includes a bottom plate, a protective edge disposed around the periphery of the bottom plate, a containing space defined by an enclosure jointly formed by the bottom plate and the protective edge for containing an electronic device, and a heat dissipating plate installed in the bottom plate, so that the heat generated by the electronic device installed with the protective cover is dissipated through the heat dissipating plate to the outside to achieve a good heat dissipation effect during the operation of the electronic device without the need of removing the protective cover and assure the service life of the electronic device. Meanwhile, the electronic device can be operated without removing the protective cover, so that the protective cover will not be lost easily, and this design can eliminate the trouble and inconvenience of the users.
