WebNov 10, 2015 · Capillary Pumped Loop can be used for cooling of high power electronics. The present paper describes the world's first use of a CPL inboard a train. The CPLIP-3 demonstrator used two CPLs equipped with two flat evaporators in parallel, a common air exchanger and filled with methanol as working fluid with a 6 microns nickel wick. WebJun 14, 2012 · Loop heat pipes are similar to a competing technology called Capillary Pumped Loops (CPL). The CPL was invented in the US in the 1960's, but has only recently (early 1980's) received much attention. …
WebOct 3, 2024 · The Capillary Pumped Loop 2 (CAPL-2) payload was an in-orbit microgravity demonstration of the full scale capillary pumped loop system planned for (and subsequently used on) the Earth Observing System (EOS) Terra Mission. The CAPL-2 payload flew on STS-69 in September 1995. WebThe proposed CTPL differs from the traditional loop heat pipes and capillary pumped loops in the evaporator design, which provides inherent tolerance to shock and vibration. Two additional features are added to further improve the shock and vibration tolerance: (1) graded wicks are used in the evaporator to mitigate the shock and vibration ...
