Description

"one

The invention relates to heat engineering and can be used in heat pipes.

The purpose of the invention is to intensify heat transfer in the evaporation zone and reduce energy consumption.

Fig, 1 shows the proposed heat pipe; in fig. 2 shows section A-A in FIG. one,

A vertical heat pipe with evaporation zones 1, transport 2 and condensation 3, comprises a housing 4 and a coaxially located inside the monotonically extending towards the zone I evaporation an insert 5 that forms the central 6 and peripheral 7 channels connected by holes 8-10, which are made on the insert in the zone, evaporation at the ends of the evaporation zones 1 and condensation 3 will be squeezed. With this insert. 5 is mounted in the housing 4 in bearings 11 for rotation and provided with internal longitudinal fins 12 with the formation of sectors 13, the holes 8 are made with edges j bent away to the side of the peripheral channel 7, in which, in turn, in the evaporation zone 1 additionally install annular pockets 14, and in zone 2 of transport in the riverbed are placed the lobe / 2

The apparatus 15 and 16, fortified respectively on the housing 4. and in the inset 5.

The proposed heat pipe works as follows.

When heat is applied to the evaporation zone 1, the coolant in the pockets 14 begins to boil, and its vapors along the peripheral ry channel 7 move towards the condensation zone 3, interact with the blades 5 and 1 6 and bring the cone box 5 into rotation. In this case, the condensate through the holes 10 enters the central channel 6 and under the influence of centrifugal forces rises upward along the inner surface of the conical insert 5 in the form of a liquid film. Partially condensate is sprayed through the holes 8 onto the wall of the casing 4 of the evaporation zone 1, and the other part of the condensate is distributed evenly across the surface of the evaporation zone 1 through the upper end of the insert 5 and flows as a film, taking heat. The presence of sectors inside the insert 5 and the holes 8 contributes to the penetration of the coolant to different height sections of the 1. evaporation zone. Thus, a thin film is formed.
