|Practical comparison on heat pipes versus vapor chambers in various heat spreading applications to show total cost vs. benefit.|
|Keywords: heat pipes , vapor chambers, cost vs.performance|
|This paper will look at various practical aspects of using vapor chambers to augment heat spreading in a solid metal heat sink base, comparing their thermal results to heat pipes with resulting temperature rise data and showing costs associated with each option. The paper will also explore the size ratio of heat spreader in relationship to heat input contact footprint. In detail the paper will discuss thermal results of both vapor chambers and heat pipes in various contact area ratios (percentage) of heat input area versus the overall size of the heat spreader. Additionally costs of each option will contrast the thermal results results achieved. Of significance are the costs associated with each method and heat input ratio size as they relate to tooling dollars, part price and increased product launch schedule.|
