High power density onboard electrical/electronic equipment cooling system for modern commercial transport airplane, has two heat exchangers, where one of exchangers cools heat transfer fluid by thermal coupling to external ambient air

摘要

The system (1) has a heat exchanger (5) transferring heat of a heat transfer medium circulating in a closed cooling circuit (4) towards heat transfer fluid circulating in another closed cooling circuit (6), by evaporation of the heat transfer fluid circulating in the latter closed cooling circuit. Another heat exchanger (7) permits condensation of the heat transfer fluid circulating in the latter closed cooling circuit. The latter heat exchanger cools the heat transfer fluid by thermal coupling the external ambient air.
