So what is a Heatpipe?
In simple terms a Heatpipe is a super heat conductor, and the device can exhibit a thermal conductivitiy that is in excess of 100 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 diameters ranging from 3 to 50 mm, and lengths which may be from only a few centimeters to several metres long.
Other sections include rectangular, flattened and also annular Heatpipes with an open centric bore section.
How does a Heatpipe work?
A heatpipe comprises of a sealed evacuated metal envelope containing a porous capillary action wick linning and is charged with a working fluid.
The prefered working fluid is usually high purity water or alcohol which exists as a saturated vapour inside the vessel.
When heat is applied to any point along the external surface of the heatpipe, the fluid inside the heatpipe evaporates at this point and then condenses again at any other points at fractionally lower temperatures.
The working fluid is returned to the evaporator area by capillary forces developed in the capillary wick lining.
In so doing, the latent heat capacity of the working fluid is utilised to effect a very efficient energy transfer, with only a very minimal internal thermal resistance.
DAU Super Thermal Conductors are engineered to very exacting standards to achieve superb thermally conductive performance properties.
STCs enable large quantities of heat to be transmitted with only very minimal thermal resistance from heat source to suitable engineered heatsinks.
Furthermore DAU STCs provide:
- Extremely High Thermal Conduction
- Fast Response to Thermal Loading
- Silent Operation
- Highly Reliable
- No Moving
