Automotive Display HUD Case Study

Automobiles continue to be at the vanguard of technology convergence. One example of this is after market head-up display (HUD) devices that project information for the driver directly above the steering wheel of a car. A prime example of these innovative devices is Navdy’s upcoming head up display that links with an Android or iOS phone to display various notifications from the phone onto a transparent screen. The display allows the driver to control the HUD using hand gestures and voice recognition so the driver can keep their eyes focused on the road.

The largest threat to the success of this groundbreaking driving device is thermal management. The sophisticated electronics and projection system contained within the device is subject to varying and often high temperatures as it is mounted to the dashboard of the vehicle.

Because of the mounting location, both storing and operation conditions pose a threat. The worst storing condition is also one of the most common, when a vehicle is parked out in the open on a hot, sunny day. The ambient temperature rises drastically as solar loading pours heat energy into the car and the unit’s top surface. During operation there are several crucial components inside the unit that need to be maintained below a specific temperature for the unit to function properly.

To understand these problems and develop an effective thermal solution forth HUD, Navdy hired Aavid, Thermal division of Boyd Corporation.
