Description

one .

The invention relates to heat engineering, can be used to thermally stabilize objects, and is an improvement on a heat pipe according to ed. No. 994899.

The purpose of the invention is to automate the regulation.

The drawing shows the proposed heat pipe, a general view.

The heat pipe includes a housing 1 with evaporation zones 2, transport 3 and condensation 4, the axis of which is fitted with an insert 5 j on the outlet end of the latter installed NASA / OK 6 in the form of a Lawal nozzle, reinforced with guide vanes 7. In addition, in insert 5 At the end of the evaporation zone 2, a tuning needle 10 is installed using the bellows 8 of the adjustment screw 9.

At the end of the condensation zone 4, an bellows 11 is additionally installed, connected by means of the rod 12 to the tuning needle 10, the cavity of which is communicated by means of the pipeline 13 to the evaporation zone-2, and the adjusting screw 9 is spring-loaded in the direction of the bellows 8 by means of. springs p 1 14 and nuts 15.

Tegsov pipe works as follows.

When heat flux is supplied to the evaporation zone 2, the resulting coolant steam enters the insert 5 and then through the annular gap between the insert 5 and the needle 10 it flows to the nozzles 6 and the condensation zone 4. The non-condensible gases generated during the operation of the heat pipe and accumulating as a layer in the condensation zone 4 are ejected into the annular gap of the nozzle 6, which is twisted with

Loop (1 current 7. At the same time, due to turbulization of the boundary layer, the process of condensation of the steam of the heat generator in the condensation zone 4 is intensified. The heat carrier condensate formed in the condensation zone 4 returns to the evaporation zone through the wick.

When the value of the heat supply to the evaporation zone 2 changes. The steam consumption of the heat transfer fluid from the evaporation umbrellas 2 to the condensation zone 4 increases, which causes a corresponding increase in pressure in the volumes of the evaporation zone 2, insert 5 and the associated bellows 11. As a result, stretching occurs the bellows 11 and the corresponding movement of the tuning needle 10 stem 12 connected with it, which causes an increase in the cross-sectional area of the annular gap between the insert 5 and the needle 10. Therefore, the increasing steam flow rate of the coolant can be transferred to the zone 4 with slightly increased pressure drop. This increase in saturation pressure slightly affects the temperature of the medium to be cooled.

The adjustment of the heat pipe in case of transition to other cooling modes is carried out with the help of an adjusting screw 9 and a nut 15. With the rotation of the screw 9, the position of the needle 10 relative to the insert 5 changes, i.e. the initial value of the annular gap and the degree of akati of the bellows 8 is established. With the help of the nut 15, the compression of the spring 14 is varied and the degree of sensitivity to the change in the control pressure in the bellows 1 1 or is established. however, the stiffness of the bellows 8 is compensated for by adjusting the gap with the screw 9.
