A dielectric heat pipe (DHP) with glass electric insulator was constructed and tested. Freon R365/227 was used as a working fluid in the DHP. The bar electrode was introduced into the condenser section to determinate the electric field influence on condensation of the working fluid vapour. The high voltage potential (AC and DC) was connected to the bar electrode. On the basis of experimental data the DHP working characteristics were made. Under the high voltage potential the temperature of the condenser section decreased and the thermal conductivity of the DHP increased (about 5 %).
