Abstract
Avionics cooling is quickly becoming the limiting factor of aircraft/spacecraft performance and reliability, particularly with the rapidly increasing power density, and decreasing module size. This paper looks at the high-efficiency heat removal using loop heat pipe technology, as an advanced two-phase thermal control method by reducing the thermal resistance between the heat sources and heat sinks. Two high performance loop heat pipes (LHPs) are developed and experimented. The test results show that LHPs can well work at the heat load up to 663 W, with low thermal resistance of 0.042°C/W.
