A Parametric DOE Study of Various Factors that Influence the CD Temperature in Automotive Radios 2005-01-0566

A continuous demand for added multimedia features in the automotive audio systems not only requires adequate cooling of the internal electronics, but also the media itself. Thermal engineers focus their efforts only on keeping the electronics below thresholds by conventional methods such as internal fans, heat sinks, etc., while overlooking the CD media.
The environment within the instrument panel (IP) poses a challenge in maintaining the media at a temperature level that is comfortable to the human touch.
This paper investigates the effectiveness of various factors that influence the CD temperature in a car player. These factors represent independent and interactive effects of the three modes of heat transfer.
In this study, a design of experiment (DOE) technique is utilized to generate a response function that filters insignificant parameters and their interactions, in order to minimize the CD temperature. This investigation would then lead to a method that combines various factors at their optimum levels to achieve the maximum cooling effect on the media.
