description The utility model relates to a digital video recorder and a temperature control device, wherein, the digital video recorder is provided with the temperature control device which can perform radiating or heating treatment by automatic control according to the temperatures of different work environments. The temperature control device comprises a heater, a radiator, a temperature sensor module, a signal transmission module, a signal processing module, a high-temperature control module and a low-temperature control module, wherein, the temperature sensor module is used for receiving a temperature signal transmitted by the signal transmission module, then sending out a radiating control signal when judging the temperature signal is too high, and sending out a heating control signal while judging the temperature signal is too low; the high-temperature control module is used for controlling the starting of the radiator according to the radiating control signal, and is connected with the signal processing module and
