Heat pipes are closed systems whose thermal conductivity is based on a thermodynamic cycle of evaporation and condensation of a liquid. Heat pipes can transmit high thermal flows with only a minor temperature gradient. The thermal conductivity of a heat pipe filled with water is 20 to 50 times greater than that of an equivalent copper pipe. Heat pipes are therefore especially well-suited for rapid spot heating with full capacity. They offer ideal options for external heat transmission in cramped installation situations. Heat pipes can also be used as a heat splay in heat sinks.
Advantages of heat pipes:
- Rapid spot heating for full performance
- Ideal for transmitting heat in cramped installation situations
- Freedom of design and flexibility provided by increasing the number of heat pipes
- Selecting qualified heat pipes provides for a long service life
- Working temperature of up to 275 °C
- Applications possible at temperatures as low as –40 °C when alcohol mix is used
