So... was considering heat transfer...

Flat surfaces and tubing really sucks! Limited area for the heat to be transferred to from the block to the tubing. What are the options?

  1. Wrapping the tubing around a block (or a cylinder) with a groove cut for it.
  2. Same as #2 with a matching outer casing.
  3. Submersing into a fluid.

#1 : Only about half of the tubing gets the heat transferred from the heater.

#2: Parts must match exactly in order not to damage the tubing. Also, makes the application of the heater much more difficult.

#3: Add a liquid to the handling, and thus more risks.
