When the heat load changes, the T {p-azov boundary moves accordingly, freeing or hurt- ing the new areas of the condensation zone, which ensures the stabilization of the pipe t-ry. At the same time, M 6 can relocate between the inner and outer limits and a constant pressure is maintained in the working range equal to the pressure okrul (moreover, which helps to achieve control accuracy.

Description

one

The invention relates to heat engineering, in particular to adjustable heat transfer devices.

The aim of the invention is to improve the accuracy of regulation.

The drawing shows schematically a gas heat pipe, a longitudinal section.

The gas-regulated heat pipe contains a hermetic body 1 partially filled with heat carrier with a wick 2 on its inner surface, zones 3 and 4 of evaporation and condensation, respectively, and a gas reservoir 5 having a flexible wall in the form of an inelastic membrane 6 bounding the body 1 from the end. The tank 5 inside the housing 1 is separated from the condensation zone 4 by a membrane movement limiter 6 made in the form of a transverse partition 7 of capillary-porous material connected to a wick 2. Outside the membrane 6, the external movement limiter in the form of a perforated casing 8 is connected to the body 1. The vapor-gas boundary is conventionally shown by line 9. The membrane 6 can be made, for example, from a thin sheet of fluoroplastic.

Heat pipe works as follows.

When heat is supplied and removed to the evaporation and condensation zones 3 and 4, respectively, heat and mass transfer is carried out through the pipe with a change in the state of aggregation of the coolant. With changes (fluctuations) thermal

the load is moved accordingly by the lem.

the vapor – gas boundary liberates or occupies new areas of the condensation zone, which ensures the stabilization of the pipe temperature, while the inelastic membrane can move between the inner and outer limiters and in this working range the pressure in the pipe is almost constant, equal to the ambient pressure that. contributes to the improvement of regulation accuracy. The septum 7 removes condensate droplets from the capillary-porous material upon contact with the membrane 6, which thus returns to the wick 2, which also contributes to the stability of the heat transfer characteristics of the pipe.
