What is a heat pipe?

7 Jan 2019
A heat pipe is a sealed hollow tube that contains a small amount of liquid, usually water or refrigerant, under vacuum. Heat pipes are designed to transfer heat from one end to the other with extremely high efficiency. When heat is applied to one end of the pipe, the liquid inside evaporates, turning into steam. This vapor then flows to the cooler end of the pipe, where it condenses into a liquid, releasing the absorbed heat. The liquid then returns to the hot end via capillary action or gravity, and the cycle repeats.

The effectiveness of a heat pipe heatsink lies in its ability to transfer heat through two primary mechanisms: conduction and phase change.
1. Conduction: Heat pipes are usually made of materials with high thermal conductivity, such as copper. When heat is applied to the evaporator portion of the heat pipe, it conducts heat to the liquid inside, causing it to evaporate.
2. Phase Change: The phase change from liquid to vapor is where the magic happens. This process absorbs a large amount of heat (latent heat of vaporization) without a corresponding increase in temperature. The vapor then moves to the condenser section where it releases heat and condenses back into a liquid.
This combination of conduction and phase change allows heat pipes to transfer heat from thermal components more efficiently than traditional heat sinks that rely solely on conduction and convection.
Applications in the field of electronics
Heat pipe heat sinks are used in a wide variety of electronic applications, from computer processors to LED lighting systems. For example, in high-performance computing, CPUs and GPUs generate large amounts of heat during operation. Heat pipe heatsinks can effectively remove heat, maintain optimal operating temperature and prevent thermal throttling.
In addition to computers, heat pipes are used in power electronics, telecommunications equipment, and even renewable energy systems such as solar panels. Their ability to manage heat in compact spaces makes them ideal for modern electronic designs, where space and weight are often at a premium.
