FAQs

What is the function of a heat pipe?
A heat pipe's primary function is to transfer heat from one location to another, using a wick and a working liquid in order carry this heat.

What are the benefits of using a heat pipe?
The primary benefit of a heat pipe is its ability to transfer heat passively. This means that you need no other power source to transfer the heat except for the heat source itself. Heat pipes are also relatively low maintenance, as they are self contained systems and have no moving parts (besides the fluid within them).

How does a heat pipe work?
A heat pipe relies on a temperature difference between its two ends. At the end closer to the heat source, the fluid within it vaporizes and travels to the other end, where it condenses back into a fluid, dissipating its heat and traveling back to begin the vaporization condensation cycle again.

What are some applications for heat pipes?
There are many applications for heat pipes, and they're very commonly used in projects where passive transfer of heat is a big advantage. For example, heat pipes are often used on spacecraft to provide cooling, as they don't require additional energy that is at a premium while away from earth. They also have terrestrial uses as well, such as keeping computer components cool to avoid overheating. These are just a couple of common heat pipe applications, but there are many more not mentioned here.

What should a heat pipe be made of?
What a heat pipe is made of is heavily dependent on its purpose and the other components. For example, the thermal conductivity of your main material is an important aspect of how the pipe will transfer heat, and different projects may call for different materials. It's also important to know how compatible is with your working fluid. Your choice of material may vary depending on if you're using water as the working fluid as opposed to a refrigerant. It all comes down to compatibility, and doing the research required to ensure that your heat pipe works well for its intended use.
