Round Heat Pipe ATS Part#: ATS-HP-D5L200G40W-003 Description: Closed evaporator-condenser heat transfer systems. A heat pipe’s 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 at the condenser end. For Illustration Purposes ONLY.
