HIGH-TEMPERATURE HEAT PIPE Russian patent published in 2004 - IPC

FIELD: heating engineering.

SUBSTANCE: pipe has hermetic body partially filled with heat carrier with zones of condensation and evaporation, made of dielectric material with protective metallic cover closely enveloping it on the outside, cap, fixed on body at end of evaporation zone, on which inside the body a heater is fixed in form of pair of electrodes made of plates made of electrolysis-resistant material and mounted in parallel to each other or perpendicularly to axis of body, power of electrodes made in alternating current, heat carrier is made of electro-conductive material, at end of body in condensation zone a pressurizing plug is mounted, at end of which a container with getter is fixed, while as dielectric material of body ceramics is selected, on inner surface of which being in contact with heat carrier a layer of melting-resilient material is applied, for example, tungsten, combined with heat carrier gases, hermetic body is filled with heat carrier in hard condition, electrodes are mounted in heat carrier, depth of immersion of upper electrode h into heat carrier and level of feeding of liquid heat carrier H into body are connected by relation h/H-0.65-0.75. Also, heat pipe is provided with sensor of heat carrier level in the body, for example, in form of current resistance sensor, between electrodes and system for automatic heating control and operation of heat pipe.

EFFECT: higher efficiency, higher reliability, higher durability.
