Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle-mounted navigators, and particularly relates to a heat dissipation structure of a vehicle-mounted navigator. Background Art

[0002] The car navigation system is an indispensable part of modern cars. It integrates advanced positioning, map display, route planning and voice guidance functions to provide drivers with comprehensive navigation services. The car navigation system will generate a lot of heat after working for a long time, so a heat dissipation structure is needed to discharge the heat to prevent heat accumulation and reduce the service life of the car navigation system.

[0003] A Chinese patent application with publication number CN216546015U discloses a high heat dissipation and shock absorption vehicle navigation, including a mounting frame and a vehicle-mounted navigation device, wherein the vehicle-mounted navigation device is movably arranged inside the mounting frame, the inner wall of the mounting frame is provided with a second groove, the side of the vehicle-mounted navigation device is fixedly connected with a connecting block, the connecting block is slidably installed inside the second groove, the side of the mounting frame is provided with a third groove, a first fan is installed inside the third groove, the inner wall of the third groove is provided with an air inlet, the inner wall of the mounting frame is provided with a first groove, the inside of the first groove is provided with an air outlet, the air inlet and the air outlet are connected, the utility model improves the heat dissipation capacity of the vehicle-mounted navigation, facilitates the rapid and timely discharge of the heat generated during its operation, thereby improving the stability of the vehicle-mounted navigation and improving the service life of the vehicle-mounted navigation.

[0004] Although the heat generated by the car navigation system is discharged in time through ventilation of the fan and heat dissipation of the heat plate and the heat pipe, the heat generated by the car navigation system during operation cannot be quickly discharged only through air cooling. The engine components of most vehicles are located at the front of the vehicle. During the driving process of the vehicle, the engine generates a large amount of heat, which will heat the nearby air, making the temperature of the air sucked by the fan high, resulting in the car navigation system being unable to cool down quickly. The car navigation system is prone to damage to its internal electronic components when working in a high temperature state for a long time, thus reducing the service life of the car navigation system. To this end, we provide a heat dissipation structure for a car navigation system to solve the above problems. Utility Model Content
