Product Code:SAE AIR1277 Title:Cooling of Modern Airborne Electronic Equipment Issuing Committee:Ac-9 Aircraft Environmental Systems Committee Scope:This document contains information on the cooling of modern airborne electronics, emphasizing the use of a heat exchange surface which separates coolant and components. It supplements the information contained in AIR64 for the draw through method and in AIR728 for high Mach Number aircraft. Report contents include basic methods, characteristics of coolants, application inside and outside of the "black box" use of thermostatic controls to improve reliability and system design. Characteristics of typical cooling components are treated sufficiently to permit selection and to estimate size and weight.
