Additive Manufactured Titanium-Ammonia Heat Pipes for Space Electronic Devices

Overview

Additive Manufacturing (AM) is a unique fabrication method that enables complex and flexible geometry designs for a wide range of components, including two-phase thermal management components like heat pipes. This project focuses on titanium-ammonia heat pipes used for future space electronic payloads like satellites and comparing their performance against conventionally manufactured heat pipes with screen mesh capillary wicks. AM increases the ability to integrate components into chassis elements, directly cool electronics components, and improve the functionality against gravity which eases ground testing. Both AM and screen mesh wick structures offer enhanced evaporator heat flux versus aluminum-ammonia, grooved wick heat pipes, enabling direct thermal management of electronics components.
