If you turn off the pump on a longer drive, let it boil, then you just fill it up before the next time you expect it to work. Maybe there would be a more elaborate way of having a reservoir which would refill the system with the circulation pump the next time it's turned on, without having the reservior be part of the circulation circuit.
Edit: Maybe position the pump and reservoir as low as possible, so that with the pump off, water would drain back to the reservior, away from the heat exchangers. Sizing the reservior to be running near empty while the pump is on / system circulating |
This is basically the other idea that I've been toying around with in my head. A second second coolant loop with gravity drain back that is open to the atmosphere. I even drew up a quick diagram yesterday before coming up with the air idea. At the moment, I think that this idea would probably be more effective (able to move more heat), but it'll also cost more and is more complex. So, for now I think I'll be pursuing the air idea. I'd encourage someone else to try it though! I'd love to see testing and results.
There are issues to deal with in this scenario, but I'd like to keep this thread about the air idea. Feel free to make another thread on this though as I'd love to discuss and develop the idea.
Here is the diagram I made for it.
