Abstract
The utility model relates to a heat dissipation structure of a vehicle-mounted navigation system. The heat dissipation structure of the vehicle-mounted navigation system comprises a heat-emitting element support, a side insulation heat plate support and a heat dissipation sheet which are arranged at two sides of a heat-emitting element in a parallel manner. In an actual heat dissipation process, the heat-emitting element can be completely isolated from the interior of a machine through the side insulation heat plate support, and therefore, the other electronic components inside the machine can be prevented from being affected by high temperature of a power amplifier; a heat dissipation space for natural up-down convection can be formed between the heat dissipation sheet and the side insulation heat plate support, and therefore, the heat dissipation efficiency of the heat dissipation sheet can be improved; and at the same time, fins are additionally arranged at two side surfaces of the heat dissipation sheet, and therefore, the heat dissipation area of the heat dissipation sheet can be increased, and the heat dissipation efficiency of the heat dissipation sheet can be improved.
