The invention relates to electrothermal, namely the temperature control of complex geometric shapes, and can be used in industries such as building, for heating various elements of the structure, as well as in everyday life, medicine, celosamente and other industries.

A device for carrying out physical-therapeutic procedures, containing a sealed bag-like container for medicinal substances with an inner insulating coating, in which the elastic longitudinal ribs of elastic material introduced heating elements (A.S. No. 914068, CL A61F 7/00, 1982, USSR).

Known multi-layer package for temperature control of complex geometric shapes containing outer and inner protective layers placed between stacked insulating strips and strips of conductive material with electrically insulating layers that are connected at the ends of the conductive jumpers (A.S. No. 1496759, CL A41D 13/00, 1989).

Also known multilayer package for temperature control of complex geometric shapes containing inner and outer protective layers of waterproof and dustproof fabric placed between the insulating strips and the strips of conductive material, which is made from attainihienty, the outer layers are in the peripheral areas equipped with textile fastener, coupled along the lines of mates and additionally fixed mechanical clamps (see patent No. 2225083, CL NW 3/36, WV 27/02, A41D 13/00).

The main disadvantage of the known devices is that in case of large complex geometric shapes dismantling of long sections at the launch site with thermostatic products is very difficult. This is because the design of long sections, in which the insulating strip disposed between waterproof and dustproof cloth, do not allow them evenly to collapse into a compact package because of a difference of thicknesses of materials.

In addition, the strips of conductive material length 4.0-4.5 m voltage drop occurs along the length tokovodov, and given the fact that the supply voltage for these devices is 24-32 V, then the voltage drop in the peripheral zones tokovodov significantly (1.2-1.3 times). It should also be noted that the operation of the multilayer stack approximate power is about 10 kW, the total current is about 300 W, i.e. for each section accounts for 30 (10 sections), the width of tokovodov in each individual section should be 35-40 mm. this circumstance to decrease the AET effective area of the heating element and affect thermal characteristics of multilayer package.

The closest analogue, selected as a prototype, is the patent of Russia №2225083, CL NW 3/36, WV 27/02, A41D 13/00, 2004.

The main task is the development of such a multi-layer package and products based on it, which would have excluded the above mentioned disadvantages, i.e. developed device must be capable of temperature control of complex geometric shapes and to be efficient in operation.

The technical result that can be obtained from the use of the invention is to increase efficiency and operational reliability of the multilayer stack to a temperature of complex geometric shapes.

The main problem is solved and the technical result is achieved due to the fact that in a multi-layer package for temperature control of complex geometric shapes containing outer and inner protective layers placed between stacked insulating strips and strips of conductive material with electrically insulating layers, the multi-layer package replicates the geometry of a controlled product and is made of separate sections, exterior and protective layers are of waterproof and dustproof fabric in the peripheral zones equipped with textile clasp fastened together along the lines of the pair at nodes of intersection of teplota the operating gaskets and additionally fixed by mechanical fixing devices, the upper part of the multilayer stack consisting of a conical part and a cap mounted on the head part of the product, and a cylindrical part, consisting of separate sections, is provided on the final perimeter of the apron with a through hole connected with the body, according to the invention the heat-shielding gaskets are made from high density foam given the estimated thickness, while the tapered portion of the multilayer stack made in the form of books from separate sections, mechanically fastened together along the lines of the pair and placed in separate zones on the perimeter of the head portion controlled products, as a separate section of the cylindrical part of the multilayer stack is also made in a book of two or more constituent elements, mechanically fastened together along the lines of mates and located on the generatrix of the cylindrical part termostatico product, and the final section of the composite element is equipped with a apron with through holes or without them, performed with him for one and repeats the geometry of the transition compartment.

Also according to the invention foam high density duplicated with two layers of foam, which is placed between the resistive element in the form of conductive fabrics, containing on the basis of the power electrode is of tinsel threads and the fuel zone in the form of strips of a given width of the electrically conductive threads, when this strip of electrically conductive threads are isolated from the power electrode insulating yarns and weft conductive fabric distributed insulating yarns and alternating current distribution electrodes of tinsel threads, evenly distanced from each other and intersecting with glitz, insulating and electrically conductive warp threads.

Also according to the invention in the resistive element peripheral zone power distribution of electrodes placed in the array of insulating threads, alternating chopped it with one or the other side of the strip of electrically conductive threads and together with the power electrodes form a switching comb specified resistive element, the ends of power and power distribution electrodes soldered copper foil, tin tin, and the cord with electrical connectors, and power cords are fed through a lot of the multilayer stack, where each element and each separate section for forming articles are interconnected electrical connectors.

Distinctive features are essential, because each of them separately and together is aimed at solving the problem and achieving a new technical result.

Use as insulating strips at the dock foam high density calculated thickness will provide temperature control of complex geometric shapes without built-in multilayer package heating system during the short-term effects of climate factors, for example during transportation of the rocket from the Assembly and test facility at launch complex with subsequent rises with the dismantling of the multi-layer package for temperature control of the head fairing.

The presence of duplicated high density foam with two layers of foam, which is placed between the resistive element in the form of conductive fabric on the basis of glitz and electrically conductive threads, will provide temperature control of complex geometric shapes with prolonged exposure to harsh environmental factors without the use of air systems provide temperature control of the rocket.

Use as a resistive element conductive fabrics, containing on the basis of the power electrodes of tinsel threads and the fuel zone in the form of strips of a given width of the electrically conductive threads, and duck - insulating yarns and alternating current distribution electrodes, evenly distanced from each other and intersecting with glitz, insulating and conductive warp threads, will allow you to create a resistive element with a longitudinal cross-switching circuit and, consequently, will provide a parallel electrical connection of the individual elements of each section, as well as to increase performance and reliability is the outer coat of the multilayer stack.

These distinctive features are new since their use in the prior art, analogs and prototype not found, which allows to characterize the proposed solution meets the criterion of novelty.

One set of new essential features with commonly known essential features that allow one to solve the problem and achieve new technical result, and this, in turn, allows to characterize a new technical solution significant differences compared with the prior art, analogs and prototypes. A new technical solution is the result of scientific-research and experimental-design work and creative contribution, obtained without the use of standard design solutions or any of the recommendations in its originality and content performance meets the criterion of "inventive step".
