Round Heat Pipe
ATS Part#:
ATS-HP-D3L100S18W-112
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.

HEAT PIPE JOINING TECHNIQUES
1) For small batches/prototypes, heat pipes
can be joined to heat sinks or other pieces
with thermal epoxy.

2) For optimal results, heat pipes should
be soldered using low temperature solder
at temperatures above 139°C but no
greater than 250°C.
