ABSTRACT: This paper researches a design process of a parallel plate-fins heatsink subjected to an impinging airflow in a broadcast vehicle system. It is demonstrated theoretically that the thermal conductance between the plate and the air stream can be maximized by optimizing geometric parameters. The research studies the theory of heat transfer across parallel plate-fins of the heatsink to optimize the geometric parameters. Those parameters are used to design three-dimensional heatsink. In the next step, the design model is used to simulate temperature under working conditions by using computational fluid dynamics (CFD) in Solidworks software. The simulation results show that the maximum temperature is smaller than the maximum permitted temperature of electronic equipment that given by manufacturer. Then, the design model is trial manufactured for testing before moving to mass production.

KEYWORDS: Heatsink, broadcast vehicle system, optimal geometric parameters, maximum temperature, CFD.
