Abstract

The invention relates to heat engineering and makes it possible to increase the heat transfer capacity. The heat pipe contains a horizontal casing 1 with zones 2 and 3 of evaporation and condensation on diametrically opposite sides of its cross section and a steam duct 4. Throughout the entire length of the evaporation zone 2 an insert 5 is installed, forming with the case 1 parlift channels 6 for a heat carrier, divided into sections 7 by means of transverse ribs or corrugations. Angles 6 are connected to the steam channel 4 in the upper and lower parts of the insert 5 by holes 10 and 11, respectively. In the steam channel 4 with a gap 12 relative to the insert 5, a longitudinal vertical partition 13 is installed, in contact with the case 1 by the upper side. During the operation of the pipe, the two-phase flow moves up along the parlift channels 6 upwards, a part of the liquid evaporates and then the entire stream enters the partition 13, from where the liquid rushes down, and the vapor condenses as a thin film onto the surface of the condensation zone 3 5 il.

Description

The invention relates to heat engineering and is an improvement of the known technical solution for auth. St. No. 1399639,

The purpose of the invention is to increase the heat transfer capacity when placing evaporation and condensation zones on diametrically opposite sides of the cross section of the housing.

Fig, 1 schematically shows a heat pipe with a cylindrical insert, longitudinal section; in FIG. 2, section A-A in FIG. one ; in fig. 3 - a pipe with flat walls and a corrugated insert, longitudinal section; FIG. 4 is a section BB in FIG. 3; . figure 5 - section bb In Fig.Z.

The heat pipe contains a horizontally arranged cylindrical housing G with zones 2 and 3 of evaporation and condensation, respectively, on diametrically opposite sides of the cross section and steam channel 4 " on section

a longitudinal partition 13 arranged in a vertical plane and contacting the upper side with the housing 1.

Heat pipe works as follows.

When heat is applied and removed in the corresponding zones between these zones, heat and mass transfer is carried out with a change in the aggregate state — i, and no heat transfer medium, while in parlift channels 6 the two-phase medium rises up; and the entire stream enters the partition 13, where the liquid and vapor are separated, the first rushing down and the latter condensing as a thin film on the surface of the condensation zone 3, which contributes to an increase in the heat transfer capacity of the pipe,
