Abstract: The paper presents a few solutions for energy saving by the use of the devices/installations using heat pipes.
A heat pipe is a heat transfer device with an extremely high effective thermal conductivity. This device transfer heat by the evaporation and condensation of a working fluid and can transfer a large quantity of heat with a relatively small temperature drop because it transports this heat in its latent form.
Heat pipes are used for a wide variety of applications covering the complete spectrum of heat transfer applications. They are ideal for any application were heat must be transferred with a minimum thermal gradient either to increase the size of heat sink or were isothermal surfaces are required.
Heat pipe heat exchangers for heat recovery are very attractive namely because of their important design flexibility and their high thermal efficiency. In high quantity applications, the cost of heat pipes drops significantly and often provides the most economical solution to many applications.
