Proven Heat pipe technology is used by Synventive to provide unsurpassed temperature uniformity in its products. The heat pipe ensures even temperatures with no hot or cold spots, resulting in high quality plastics processing.
A heat pipe is an evacuated chamber (a), inside of which is a liquid and a capillary wick (b), which acts as a transport device. The phenomena of evaporation, condensation, and surface-tension pumping of liquid in the wick are used to transfer latent heat of vaporisation continuously from one region to another.
c) Consumption of energy caused by evaporation.
d) Vapor transport to a region of lower pressure. Surface tension pumping of liquid.
e) Release of energy caused by condensation.
