CAAC-PMA Approved Replacement for Primary dual heat exchanger core manufactured byHAMILTON SUNDSTRAND

Eligibility: B777

FEATURES

It is air-to-air plate-fin heat exchanger. The hot bleed air is cooled twice through the Primary Dual Heat Exchanger Core. During operation,the hot air enters the inlet of the hot air circuit, flows through fins and plates of hot chamber, and exits from the outlet of hot air circuit; the coldair enters the square flange inlet of cold air circuit, flows through fins of cold chamber, and exits from the outlet of cold air circuit. The heat of the hot air flow is conducted to the cold air flow through fins and plates, and the cold air flow takes away the heat to complete the heat exchange and achieving the goal of reducing temperature of the bleed air.
