Abstract

The invention relates to heat engineering and makes it possible to increase the heat transfer capacity of a heat pipe when the heat supply conditions change locally. The heat pipe includes a housing 1 with zones 2 and 3 of evaporation and condensation, respectively, and a high-voltage electrode placed in the first zone, made of sections 4 mounted transversely on heat-sensitive elements in the form of bimetallic plates 5 mounted on housing 1. When the pipe is in operation In the case of a local change, for example, an increase in the heat supply of the plate 5, in this area, they increase their deflection and bring their "own" sections 4 of the electrode closer to the wall of the housing 1, which leads to an increase in the electric intensity floor-parameter and heat intensity. 3 il.

an electrode made of R3 sections 4 installed with the possibility of lateral movement on the temperature-sensitive elements in the form of bimetaplic plates 5 mounted on the housing. When the pipe operates, in the event of a local change, for example, an increase in the heat supply of the plate 5, this section increases its deflection and brings its electrode sections 4 closer to the wall of the housing 1, which leads to a higher electric field and heat transfer intensity. 3 il.

FIELD OF THE INVENTION The invention relates to heat engineering, namely to heat transfer devices.

The purpose of the invention is to increase the heat transfer capacity with a local change in heat supply conditions.

Figure 4.1 shows a heat pipe, a longitudinal section; figure 2 - section aa in figure 1; FIG. 3 shows a section of the housing and one of the sections of the electrode.

The heat pipe includes a housing 1 with zones 2 and 3 of evaporation and condensation, respectively, in the first of which inside the housing 1 a high-voltage electrode is placed, made of sections 4, each of which is transversely mounted on its temperature-sensitive element (holder) in the form of a bimetillic plate 5 fixed to the housing 1 and electrically distributed with the electrode section 4 by means of a dielectric strip 6. All sections 4 of the electrodes are interconnected by conductors 7 and connected to one pole of the high-voltage current source 8. Case 1 is grounded.

Heat pipe works as follows.

by changing the state of the coolant. When the heat load changes locally, for example, when it increases in any part of the evaporation zone 2, the corresponding bimetallic plates 5 increase the bend and bring their sections 4 of the electrode closer to the wall of the pipe body 1, which causes an increase in the electric field intensity and heat transfer intensity. A similar effect will be observed with stationary uneven heat load.
