Cooler Star Amazon are a new company to us here at FrostyTech. While the company is officially called Chein Fu International Technology Co. Ltd., the Cooler Star Amazon logo is what its heatsinks are branded under. The focus of Cooler Star Amazon appears to be heat column heatpipes. These are slightly different from the standard 6-10mm diameter copper heatpipes we are used to seeing, and typically start off at 25mm in diameter or more.

According to documentation by QuTech, the heat column's used in Cooler Star's heatsinks are essentially empty cylinders of copper coated internally with a thin chemical "superconducting heat transfer medium." The copper cylinder is sealed off at both ends, and inside is under a vacuum of approximately 1 Torr.

Given that the size of the copper heat column is ideal for socket 775 and socket 754/939/940 processors, this is a cooling technology consumers are likely to be seeing much more of from many different manufacturers, not just Cooler Star.

The vacuum sealed copper heat columns come in various lengths to accommodate variously sized heatsinks as this Cooler Star Amazon exhibit showcases.

The manufacturing process is pretty simple, the extruded aluminum heatsink is made separately, and then the copper heat column is pressed into the center of the aluminum for form the finished cooler. A simple tolerance interference fit holds the copper in place and assures a good thermal interface between the two metals.

The aluminum extrusion is reamed to create an inner diameter just about the same as the outer diameter of the copper heat column. The two are then press-fit together.

Patent no. 6,132,823 explains QuTech's very interesting and potentially revolutionary adaption of heatpipes, entitled Superconducting Heat Transfer Medium. Here is a short excerpt from the patent which explains the technology in plain english.

"Inorganic Medium Thermal Conductive Device.

This heat conducting device greatly improves the heat conductive abilities of materials over their conventional state. Experimentation has shown this device capable of transferring heat along a sealed metal shell having a partial vacuum therein at a rate of 5,000 meters per second.

On the internal wall of the shell is a coating applied in three steps having a total optimum thickness of 0.012 to 0.013 millimeters. Of the total weight of the coating, strontium comprises 1.25%, beryllium comprises 1.38%, and sodium comprises 1.95%...

The fact that a conventional heat pipe shares a similar outside shape to a thermal superconductive heat pipe used to raise some misunderstandings. Therefore, it is necessary to give a brief description on the differences and similarities of the two. A convectional heat pipe makes use of the technique of liquids vaporizing upon absorbing great amounts of heat and vapors cooling upon emitting heat so as to bring the heat from the pipe's hot end to its cold end. The axial heat conducting velocity of the heat pipe depends on the value of the liquid's vaporization potent heat and the circulation speed between two forms of liquid and vapor. The axial heat conducting velocity of the heat pipe also is restrained by the type and quantity of the carrier material and the temperatures and pressures at which the heat pipe operates (it can not be too high).

The company showcased an assortment of heatpipes and heat columns hinting at a range of possibilities.

The present superconductive heat transfer device is made of a thermal superconductive medium whose axial heat conduction is accomplished by the thermal superconductive mediums' molecules high speed movement upon being heated and activated. The present superconductive heat transfer device's heat conducting velocity is much higher than that of any metal bars or any convectional heat pipes of similar size, while its internal pressure is much lower than that of any convectional heat pipe of the same temperature."
