ABSTRACT
The author proposes the total mathematical model of nonstationary thermal processes occurring in the plate heat exchangers of air preparation system of aircrafts, taking into account the heat losses to the environment and design. Heat exchanger is considered as a set of homogeneous plates, the thickness of which is significantly less than the length and the width. The solution of the differential heat conduction equation for a thin plate by the method of finite differences is presented.
KEYWORDS
plate heat exchanger, triple-flow, heat conduction equation, finite differences method.
