The Thermal Evaluation of Air-Cooled Electronic Equipment
Abstract
Air-cooled electronic equipments designed for airborne application are classified according to their cooling methods. Basic thermal test methods and techniques of making the necessary measurements are described with emphasis on bench testing. Calculation methods for the prediction of altitude performance from bench test data are presented. The analysis of altitude chamber test data and calculation methods for their correction are discussed for equipments which cannot be evaluated by bench tests only, and for other equipments for which certain data may be conveniently secured by altitude chamber test. Methods applicable to various types of equipment for evaluation of non-steady state operation are covered in detail. One chapter is devoted to the theory, performance, evaluation and selection of cooling blowers. Throughout the report, charts are presented which allow graphical means to be utilized to a great extent for purposes of analysis. All methods are illustrated by means of examples listed in the Contents. Physical property data, air flow theory, blower test methods and details of experimental apparatus are presented in the appendices.
