Description

Heat pipes transfer heat with minimal thermal resistance through a closed-loop system where liquid evaporates and condenses. They efficiently move heat within a thermal system but do not dissipate it into the environment.

A heat pipe consists of a copper tube with an internal wick and a small amount of water. When heat is applied, the water evaporates, travels to the cooler section of the pipe, and condenses, creating a pumping effect.

The performance of a heat pipe depends on its length, diameter, wick structure, and shape. A larger diameter increases capacity, while a longer length reduces it. Sintered heat pipes are the most efficient, followed by mesh and grooved types. Bending or flattening affects heat transfer. For higher heat loads, multiple pipes can be combined for better performance.

There are different wick structures:

Grooved wick – works horizontally but is limited beyond a 15° tilt.
Mesh wick – performs well up to a 30° tilt.
Powder wick (sintered) – provides the best performance in all orientations, including upside down

We only offer sintered heat pipes due to their superior performance.
