RAC Thermal Management Guidebook.

Abstract : In the light of the vital influence of temperature on the reliability of electronic equipment and the evermore stringent reliability demands of commercial products and military systems, a major concern is ensuring the implementation of a disciplined thermal management program. Many managers and engineers have little or no knowledge of thermal design and analysis. Moreover, texts and available handbooks published usually stress theory rather than practical applications. Recognizing this situation, Rome Laboratory (then Rome Air Development Center) contracted with Hughes Aircraft Company to develop the 'RADC Thermal Guide for Reliability Engineers' in 1982. This publication represents an update to that outstanding document focusing on new thermal approaches and commercial application of the techniques included. It is the result of a joint effort with Hughes and RAC engineers participating. Part I presents guidelines for assuring the development of a thermally adequate, cost-effective product. It defines the activities that should be addressed in product specifications and statements of work. And it shows how to tailor the tasks to details the implementation of these tasks. It summarizes the fundamentals of heat transfer; tells how to evaluate not only thermal designs, but the thermal adequacy of production equipment; and explains the thermal aspects of environmental screening. It gives 'do's' and 'don'ts' and rules of thumb, and shows ow to improve existing designs. Only the essence of each subject is presented. For more detailed information, references are listed in the appendix.
