The heat exchanger is typically fabricated from aluminum construction. It is designed to allow easy installation and removal for periodic maintenance. The interface features are tailored to accommodate various installations, and in some instances the cooling flow inlet and outlet headers may be integral with the ram air ducting. The heat exchanger performance can be sized to best meet the required temperature application.
Fundamentally, the air-to-air heat exchanger conditions the temperature of engine bleed air or boosted output flow from a compressor prior to delivery of the pressurized air flow to the downstream air separation module (ASM). The pressurized air flow is cooled by means of ram air or by way of an electric cooling fan using a prescribed thermal control algorithm.
APPLICATIONS:
Commercial aircraft, military fighters and transports, business and general aviation, engines, helicopters, and military ground vehicles.
FEATURES AND ATTRIBUTES:
• Cools the hot bleed air to temperature up to 154°F
• Operates in ambient temperature range of -67°F to 176°F
• Interface features are tailored to accommodate various installations
