If you can run the numbers on how thick a wall of tubing that you'll need to contain He at a somewhat high gas pressure and find a reasonable gas density that will be able to carry/transfer sufficient thermal energy, it should be fairly straight forward.

If you look around at the new technologies coming out within the automotive industry, you'll notice the use of Carbon Dioxide instead of a HCFC or HFC for the HVAC on automobiles. It would be far easier, safer, and cheaper to use Carbon Dioxide instead of trying to use Helium in any sort of environment where you'll be requiring a significant fluid density in the loop.
