Abstract

A heating and heat dissipation apparatus of an integrated camera core comprises a cooling fin, a heating resistor and a heating control circuit. Two ends of the cooling fin form right angle arms which are mutually vertical to each other respectively. A central section of one right angle arm in the cooling fin is bended so as to form a groove. An outer side surface of the groove is mutually contacted with a main chip. Another right angle arm in the cooling fin is mutually contacted with and fixed to a chassis. The heating resistor is fixed to the groove of the cooling fin above the main chip. The heating control circuit is arranged on a circuit board in a movement. The heating resistor is connected with the heating control circuit through a lead. When the main chip works, heat generated by the main chip can be timely conducted to the chassis through the cooling fin and heat exchange with the outside world is performed through the chassis so that overheating of the main chip is avoided and normal operation of the integrated camera core is guaranteed. In addition, when an external temperature of the integrated camera core is low, the heating resistor carries out preheating on the main chip so that a cold start capability of the main chip in a low temperature environment is increased.
