Heat Highway¶

The core of XO-VAC+ is what is referred to as the heat highway. This is a linked series of conductors and thermoelectric coolers (TECs) that pulls heat out of the chamber or pushes it in.

Below is a flow diagram for this showing transfer mechanisms that are primarily conduction, convection or radiation based.
