5k HEAT HELIOTROP

I

The invention relates to a helio (technique, in particular to tegshovy heliotropes for tracking the sun.

A thermal heliotrope is known, comprising a housing, a lens mounted thereon and a sensing element located in the housing, made in the form of a heat pipe with a heat-absorbing surface, an evaporation zone divided by sealed chambers with a heat-insulating wall located in the focal zone of the non-lens, and connected by flexible pipes filled with non-condensable gas to the control cavities of the body turning mechanism.

In this thermal gel of the lotus, the evaporation zone of the heat pipe is divided into two chambers, and the radiation focused by the lens is collected in the point zone IJ.

Having two cameras allows the heliotrope to track the position of the sun.

only in one plane, with the point focal zone of the lens limiting the sensitivity of the heliotrope.

The purpose of the invention is to expand the range of the heliotrope and increase its sensitivity.

The goal is achieved by the fact that in the evaporation zone of the heat pipe perpendicular to the heat insulating wall 10 there is a second heat insulating wall, the heat-receiving surface of the heat pipe is made flat and equipped with two grooves located above

15 ends of the insulating walls, the latter and the heat-receiving surface have a capillary-porous coating, the heat pipe in the condensation zone is made in

In FIG. 1 schematically shows a thermal heliotrope, section; figure 2 - the same general view. The thermal heliotrope contains a housing 1 (Fig. O, a lens 2 mounted on it and located in the housing 1 sensitive element made in the form of a heat pipe with a heat-receiving surface 3 with an evaporation zone k divided into sealed chambers 5 by a heat insulating wall b located the end face in the focal zone of the lens 2, and the condensation zone -7, connected by flexible pipes L filled with non-condensing gas, to the control cavities of the mechanism 9 for turning the housing 1. In the evaporation zone 4, the heat pipes are perpendicularly warm The insulating wall 6 is provided with a second heat insulating wall 10, the heat absorbing surface 3 of the heat pipe is made flat and provided with two grooves 11 (Fig. 2 located above the ends of the heat insulating walls b and 10, the latter and the heat absorbing surface 3 having a capillary porous coating 12 ( Fig. 1), the heat pipes in the condensation zone 7 are made in the form of four U-shaped pipes 13 (Fig. 2), which are located across the TIP ABOVE and connected to the cameras 5, the lens 2 is made in the form of intersecting, at a right angle qi In the evaporating zone 4 of the heat pipe, the hermetic chambers 5 are formed by heat insulating walls 6 and 10 together with a pallet made up of a cup 1b and inclined planes 17 that go to guide ramps 18. The capillary-porous coating 12 is brought along the walls b and 10 to the bottom of the glass 16. The lower ends of the U-shaped pipes 13, which constitute the condensation zone 7 of the heat pipe, communicate with its evaporation zone 4, and the upper parts of the pipes 13 are fitted with spiral cients 19Tsilindry lens 2 may be solid or hollow with a cavity complements of transparent zhidkos Tew. Each pair of flexible pipes 8 connects oppositely arranged. Shaped pipes 13 with a corresponding pair of bellows 15, which are freely placed in guide cylinders 20 with stops 21. The damped ends of each pair of bellows 15 are connected kinematically with a corresponding gear 23, fixed on the shaft 2 rotating in bearings 25. To each shaft 24 are fixedly attached the lower ends of the corresponding pair of rods 26 placed in vertical planes passing through the grooves 11. The upper ends of the rods 2b are a hinge on associated with the housing 1. The tubes 13 (in their places of connection to flexible pipes 8) installed check valves 27. The heat heliotrope operates sleduneschim manner. Cylinders-14 lenses 2 focus solar radiation on mutually intersecting lines lying in the plane of the heat-receiving surface 3. The rays of the Sun, concentrated along the grooves 11, symmetrically with respect to walls 6 and 10, heat the working fluid impregnating the coating 12. In all chambers 5 of the evaporator zone 4 is thermal pipes generate the same amount of vapor of the working fluid, which develops the same non-condensable gas pressure in the bellows 15, as a result of which the equilibrium of the heliotrope is not disturbed. The deviation of the focal lines of the cylinders 14 of the lens 2 to one or the other side of the grooves 11 of the heat-receiving surface 3 causes asymmetric steam generation of the working fluid in the chambers 5 and, accordingly, develops unequal gas pressure in the bellows cavity 13 of each pair, which in turn leads due to the kinematic connection of each pair of bellows 15 with the housing 1. Placement of the second heat-insulating wall 10 in the evaporation zone 4 of the heat pipe and its perpendicular arrangement to the first wall b It is necessary to create four chambers 5 / which, in combination with four U-shaped tubes 13 of the condensation zone 7 and two pairs of bellows 15, ensure the rotation of the heliotrope in two planes, which expands the range of its operation. At the same time, the implementation of lens 2 in the form of two cylinders AND, as well as the execution of a heat-receiving surface 3 of a heat pipe flat and with grooves 11 located above the ends of walls 6 and 10 in the focal zones of the cylinders k, increase the amount of perceived solar radiation and make heliotrope sensitive to the deviation of the focal lines of the lens 2 from the grooves 11, which, in turn, improves the accuracy of tracking the sun.
