Thermal Solution for Car Navigator

Introduction of car navigator:

A car navigator is a driving assistance device that can help car users accurately locate the current driving position, calculate the itinerary according to the established destination, and guide the car user to the destination through multimedia methods such as map display and voice prompts. GPS is working.

Car navigator structure:

The car navigator includes a chassis, a power supply, a core circuit board and a display panel. The chassis is usually a rectangular metal box with one end open. The power supply and the core circuit board are fixedly installed in the chassis, and the display panel is then installed in the chassis. The open end is closed; among them, the power supply is used to provide the system working voltage of the vehicle navigation system, and the core circuit board mainly provides communication, Operation, scheduling and processing functions, the display panel mainly provides display interface and input operation buttons.
