要約

Automotive vehicles are equipped with various electronic devices for human interaction and interfacing (display panel, touch panel), human comfort and entertainment (lightning, sound system, camera), proper system operation (electronic control unit), system safety (fuse-box, junction box), and so on. With increase in the performance and functionalities of these devices, cooling modules with high thermal performance and lighter weight have to be developed. LEDs (light emitting diodes) in headlamps, displays and internal lightning, and high power semiconductors in entertainment, information, and control systems are most potential areas for cooling by heat pipe-based passive thermal solution. The present investigation discusses heat pipe cooling modules developed for automotive electronics including headlamp, display panel, head-up display, sound system, and camera. Heat output from these devices range from 1 to 50 W with natural convection cooling using air. Heat pipe heat sinks have been proposed and tested for cooling 10 W and 30 W LED light functions in two headlamps, respectively. For front panel and head-up-display cooling, a heat pipe system with 3−10 W capacity was designed and tested. In addition to this, heat pipe solution for sound system and camera cooling was also evaluated. In summary, heat pipe-based cooling modules outlined in this paper will provide energy efficient and thin thermal management solutions for space conservative high density electronics in automotive vehicles.
