Round Heat Pipe
ATS Part#: ATS-HP-D10L400S49W-172
Description: Closed evaporator-condenser heat transfer systems.
A heat pipes wick structure and embedded liquid enables it to
produce a very high heat flux transport capability, which can be
10-20 times higher than the equivalent diameter solid copper pipe.
Round heat pipes offer advantages for certain fin configurations
