You should be able to make the heat pipe either with water or alcohol, alcohol of course is not going to freeze as easily but is going to have to be under a slight pressure to get it to the liquid form and that is key, to have the fluid boil then as it cools turn back in to a liquid and drain back on it's own, I would use a diluted isopropal alcohol because it likes to bond with water so as it cools the water at the lowest point will want to suck it up, but it will need to be under pressure, not sure how high, maybe 10psi?
Your idea sounds good, so I say go for it.
