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