Heat Column, A Two Phase Heat Transfer Device

Heat Transfer Column

A Two Phase Heat Transfer Device

A Highly Effective, Thermally Conductive Solution

A closed-loop heat column has the ability to conduct immense heat. The amount of heat that can be moved by way of phase change conduction is quite significant.

The heat columns are sealed, reliable, and predictable in its behaviour. Since it functions with gravity, a customized design will allow it to function as well horizontally.

The heat column is a hollow cylinder with a wick structure bonded to the interior surface. The evaporator section is the base of the column, and the walls and head of the column are the condenser section. Heat columns are paired with radial heat sinks that are attached to the heat column, providing a large surface area to dissipate the heat. However, great care must be taken to ensure that the column base is flat enough to provide a good thermal interface with the heat source.

Heat columns excel in high-power single heat source applications, since the heat spreads from the small evaporator section at the base to a very wide condenser section at the walls and cap. Heat columns are seen in L.E.D. and PC CPU thermal modules, and other industrial thermal management applications.
