Electronic components used in many non-computer related devices require cooling in order to operate effectively. While cooling of such devices does not pose difficulties as severe as those arising in computer systems, ensuring adequate thermal management can be challenging. Such components, e.g. those in industrial measuring systems, are often cooled by natural convection due to its high reliability and cost effectiveness. Adequate thermal management requires knowledge of the natural convective heat transfer rates that exist in situations arising in such devices. This research program aims to accomplish this by providing a wide range of important new basic information for use in the design of such cooling systems. Situations considered are simplified models of those occurring in real-world electronic component cooling. Components will be modeled as flat heated elements of various shapes embedded in a surrounding flat surface, and in most cases, assumed to be horizontal.

许多非计算机相关设备中使用的电子组件需要冷却才能有效运行。尽管这种设备的冷却并不像在计算机系统中产生的设备一样严重，但确保足够的热管理可能具有挑战性。这样的组件，例如由于其高可靠性和成本效益，工业测量系统中的人通常会因自然对流而冷却。足够的热管理需要了解在此类设备中出现的情况下存在的自然对流传热率。该研究计划旨在通过提供多种重要的新基本信息来实现此类冷却系统的设计。所考虑的情况是在现实世界电子组件冷却中发生的情况的简化模型。组件将建模为嵌入周围平坦表面的各种形状的平坦加热元件，在大多数情况下，假定为水平。
