2. What Is a Heat Pipe

Essentially, a heat pipe looks like a closed metal tube. Heat pipes move heat through the process of evaporation and condensation.

The heat source applies heat to one end of the tube. A working fluid inside the pipe then evaporates from the heat. Vapor then travels to the cold end of the pipe.

Condensation then occurs and releases heat. Lastly, a wick inside the pipe returns the liquid to the hot end.

Heat pipes cycle through these steps over and over again. Since a phase-change is involved, heat pipes can conduct heat far quicker than solid materials.

You may also refer to ASHRAE for standard thermal engineering materials.

3. How a Heat Pipe Works

The cycle a heat pipe uses is called a closed thermodynamic cycle.

Heat is applied to the pipe through the evaporator. A working fluid then evaporates by absorbing heat.

Vapor will then flow through the pipe until it reaches the condenser. Since vapor can flow freely, heat can be distributed effectively.

The vapor will condense back into liquid when it reaches the condenser. The wick will then move the liquid back to the evaporator.

Just remember that heat pipes continue to cycle like this.

4. Structure of Heat Pipe

A heat pipe consists of the following structural elements.

• Metal Shell

Heat pipes commonly use copper or aluminum shells. Copper and aluminum allow heat pipes to transfer heat well.

• Wick Structure

The wick structure enables capillary force. Many producers choose sintered powder method, mesh, or grooved method.

• Working Fluid

The working fluid is the medium that transports heat within the heat pipe. Although deionized water is the most widely used heat transfer medium, you can use other fluids.

• Vacuum Environment

Heat pipes are in a vacuum environment. Therefore, they exhaust all the air before sealing them.

If one element is out of balance, it can cause problems with the heat pipe. For this reason, heat pipe production requires precision machinery.

5. Production Process of Heat Pipe

The production of heat pipes can be divided into the following stages.

• Cutting copper tubes to size
• Removing impurities on the inner wall with cleaning equipment
• Inserting wick materials and sintering them with furnace
• Exhausting internal gas with vacuum system and replenishing working fluid
• Sealing both ends of the heat pipe with welding or sealing equipment
• After production, leakage tests and thermal performance tests must be performed on the heat pipes.

6. Benefits of Heat Pipe Technology

Heat pipes have many notable advantages.

They can maintain an extremely high thermal conductivity.

They can transport heat over large distances with minimal loss.

Additionally, heat pipes have no moving parts. As a result, they retain a great deal of reliability over time.

Heat pipes are also very small and lightweight. Engineers can place them in even the smallest electronics.

Thus, heat pipe technology is utilized in most modern cooling systems.

Since industries continue to value energy efficiency, heat pipes will continue to be used widely.

7. Industries that use Heat Pipes

Heat pipes enable the following industries and technologies to function:

• Cooling laptops and computers
• Cooling servers in data centers
• LED lightbulbs
• Power electronics for electric vehicles
• Aircraft
• Solar energy

Heat pipes are used in computer processors because they generate a lot of heat. Cooling systems must move heat towards heatsinks to keep these devices working.

Heat pipes allow for consistent thermal control in these cooling modules.

Internationally, energy research agencies such as the International Energy Agency recognize heat pipe technology.

8. Difference Between Heat Pipe and Vapor Chamber

Heat pipes and vapor chambers both work off of phase-change heat transfer. However, they do vary when it comes to physical construction.

Heat pipes are often cylindrical. Because of this they only dissipate heat in one direction.

Vapor chambers allow for heat dissipation across a wide flat surface. This allows for more uniform heat distribution.

Today it is common to see products that use both heat pipes and vapor chambers. Combining the two allows for the best thermal performance.
