What is a heat column?
The heat column is a sealed copper hollow cylinder that is under vacuum, with a wick structure bonded to the interior walls.
Compare to heatpipe, heat column have biger diameter of cooper tube, it can be assmblied to the heat source directly by the copper plate which at the bottom of the heat column, while heatpipe need connect with another plate.
How the Heat column works?Heat column has the same work priciple with heatpipe, 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.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. Heat columns are seen in L.E.D. and PC CPU thermal modules, and other industrial thermal management applications. Heatcolumn contructionHeat column has a sintered copper powder wick on the inner copper pipe wall and the bottom plate, and the wick is connected by special design.
Heatcolumn Benifits
The heat column has a large pipe diameter and can conduct more heat, so the thermal power can be higher; At the same time, its substrate design can be very flexible to meet more installation requirements.
