How to simulate high temperature heat pipes?

In Flow Simulation there is an option for heat pipes, but it does not have a limiting operating temperature range.  Real heat pipes only work as heat pipes within a certain temperature range.  I am specifically interested in 600K water based SS316 heat pipes for space applications.  So my question, is it possible to model high temperature heat pipes in Flow Simulation using the built in heat pipe system?  The current heat pipe system will work if I force steady state situations, but I need a startup and cool down.  I have tried using a combination of solids that act as heat pipes and the inherent heat pipe function, but it only gives me mildly reliable results.  My system looks like this:Full render.JPG
