AI Technical Summary
The heat dissipation mechanism of existing dashcams affects the normal use of internal non-heat-generating components, and external dust can easily enter, affecting the lifespan of the device.
The recorder employs a compartmentalized heat dissipation mechanism, dividing the main body into a high-temperature chamber and a low-temperature chamber. Targeted heat dissipation is achieved through heat conduction rods and a fan system, and a dust filter is installed to prevent dust from entering.
It achieves efficient cavity-based heat dissipation for the dashcam, preventing dust from entering and significantly improving the service life of internal components.
