Heatpipes for Super Thermal Conductivity
So what is a Heatpipe?
In simple terms, a heatpipe is a super heat conductor, the device can exhibit a thermal conductivity that is in excess of 300 times better than that of an equivalently sized component made from pure copper. Typically, they take the form of a rod of circular cross section with a diameter ranging from 5/16 to 2.00 inches, and lengths which may be from only a few inches, to several yards. Other sections include rectangular, flattened and also annular with an open centric bore.
How does a Heatpipe work?
A heat pipe consists of a sealed evacuated metal envelope containing a porous capillary action wick lining and is charged with a working fluid. The preferred working fluid is usually high purity water or alcohol which exists as a saturated vapor within the vessel. When heat is applied to any point along the external surface of the heatpipe, the fluid inside the heat pipe evaporates at that point and then condenses again at any other points at fractionally lower temperatures. The working fluid is returned to the evaporator area by capillary action developed in the capillary wick lining and or by gravity. In so doing, the latent heat capacity of the working fluid is utilized to effect a very efficient energy transfer, with only a very minimal internal thermal resistance.
