The Thermal Hard Pipe is an air to water intercooler made from Aluminum. Aluminum is known for the fact that is has a very fast heat transfer rate compared to other metals. When we pass heated air through the inner finned tube "Air Passage", the heated air passes over these fins and they absorb the heat. From there, we pull that heat out and away from those fins by the outer jacket's Coolant Passage.

We run a liquid through this Coolant Passage and this is used to pull the heat away from the fins, cooling the heated air in the inner Air Passage. The Thermal Hard Pipes have an incredible 101.5 inches of linear surface. This means for every inch of air passage, we have 101.5 square inches of surface contacting the heated air less the perforations.

We run the liquid through the Coolant Passage in the opposite direction of the flow of heated air in the Air Passage. This makes for the coldest possible output.
