How To Find A Quality Heat Pipe Cooling System

A heat pipe is defined as a closed evaporator system that includes sealed hollow tubes lined with wick or capillary structures. The operating temperature saturates the pores of the wick in a equilibrium state between the liquid and the vapor.

The evaporating fluid then fills the heat pipe’s hollow center and diffuses throughout its length. Condensation occurs as soon as the temperature is slightly below the evaporating area. As it occurs, the vapor gives up the heat that was required to cause evaporation. High thermal conductance helps maintain near constant temperatures along the entire dimensions of the pipe.

The 3 Major Components Of A Heat Pipe

– Vacuum tight sealed containment shell/vessel
– Working fluid
– Capillary/wick structure

A heat pipe transfers heat from the heat source (evaporator) to a heat sink (condenser) over a relatively long distance via the latent heat of vaporization through working fluid. It is important that each section is handled accordingly through all of the essential parts. Heat pipes enable passive cooling solutions for high heat loads and high temperature equipment that are lacking moving parts, allowing for more heat at a lower delta than traditional cooling methods.

3 Sections Of A Heat Pipe

– Evaporator section
– Adiabatic section
– Condenser section

Heat pipe manufacturers also provide a variety of different wicks to avoid a heat overload. You will get long lasting protection against corrosion on your equipment with quality and durable heat pipes.
