To solve the given challenges, the design focus was broken up into two parts. The first was to investigate the effectiveness of a solar shield for the unit during storage. The second to design options for active cooling inside the unit during operation.
To develop the solar shield solution, Aavid did extensive research and solar testing to design a suitable top housing that reduced the overall thermal load during storage and operating. The solar test setup has the unit inside a car and placed inside an environment chamber with a controlled solar load.
To evaluate active cooling options for operating mode, Aavid modeled the unit in CFD to improve the air flow path within the unit, thermal solutions on various components, and components placement inside the unit.
The result from the collaboration between Navy and Aavid was a head up display unit that has an innovative thermal management solution for two significant technical problems.
Aavid's solutions enhanced Navdy’s product and enabled a device higher in reliability and with a longer lifetime. The development and use of devices such as Navdy’s HUDs increase road safety for all and the more reliable they are, the safer our roads become.
