An exemplary projector includes a power supply circuit, a heat dissipation device, a rechargeable cell and a first switching circuit connected between the heat dissipation device and the rechargeable cell. The heat dissipation device is configured for dissipating heat produced by the projector. The power supply circuit is configured for powering the heat dissipation device. The rechargeable cell is configured for receiving and storing electrical power from the power supply circuit. The first switching circuit is configured for controlling the rechargeable cell to power the heat dissipation device when the power supply circuit stops powering the heat dissipation device. A related heat dissipation system is also provided.
