Since heat pipes are two phase devices, they demonstrate effective thermal conductivities ranging between 50,000 and 200,000 W/m-K, depending on the heat pipe length. Installing heat pipes into an AlSiC plate dramatically increases the plate’s effective thermal conductivity. AlSiC plates alone have a thermal conductivity of roughly 200 W/m-K and a CTE ranging from 7-12 ppm/ deg C, similar to that of silicon. An equivalent sized heat pipe embedded AlSiC plate has effective thermal conductivity ranging from 400 to 500 W/m-K and retains the CTE of AlSiC.","","","Kansas City Plant (KCP), Kansas City, MO (United States)","USDOE National Nuclear Security Administration (NNSA)","","United States","2010-01-07T00:00:00Z","English","Conference","","Conference: ITHERM 2010, IEEE, 2-5 Jun 2010, Las Vegas, Nevada (United States)","","Medium: ED","","KCP-613-8705","DE-AC04-01AL66850","","","","2013-04-22T00:00:00Z","1074137","https://www.osti.gov/biblio/1074137","https://www.osti.gov/servlets/purl/1074137","","",""
