This paper presents the experimental results of controlling an evaporator wall temperature overshoot problem under a high thermal load by applying a bypass line to the loop heat pipe (LHP). To solve the overshoot problem during the LHP start-up, any nucleation bubbles generated on the wick...

The heat transfer of an air-to-air heat pipe heat exchanger (HPHEX) with counter flow and a high-temperature range was modeled. The HPHEX was constructed from sodium-stainless steel (STS) heat pipes (HPs) using a staggered configuration. The thermal numerical model was developed by the nodal...
