Abstract

Compact plate-fin heat exchangers are extensively used in automotive, marine and aviation industries. The thermal stress in structure of heat exchange surfaces is sufficient and leads to reduction of the resource of such devices if they are used for cooling hot air (300…600 ºС). The utilization of the approach considers the variable ratio of the thermal resistance between hot and cold sides of the heat transfer surface for design of plate-fin heat exchangers, which is one of the potential prospective ways to reduce the thermal stress in the structure. The results of numerical experiments based on the mentioned approach for the modeling of pre cooler for the aviation air conditioning systems (ACS) are presented in the article. In the present study the authors established the basic appropriateness and proposed the most optimum options for design to sharply reduce the thermal stress in the structure of plate-fin heat exchangers
