MULTILAYER CASE FOR TEMPERATURE CONTROL OF COMPLEX GEOMETRIC CONFIGURATION PRODUCTS Russian patent published in 2009 - IPC H05B3/36 A41D13/00 

FIELD: electricity.

SUBSTANCE: invention is attributed to electric engineering, in particular to multilayer thermostatic pack for temperature control of complex geometric configuration products which contain outer and inner protective layers between which there are mated heat-insulation inserts and strips of current-conducting material with dielectric layers. Multilayer pack follows the geometry of temperature-controlled product. The case is made of separate sections whose layers are formed by dust-proof-and-moisture-proof fabric with textile fasteners interconnected along conjugation lines at joints of heat-insulating inserts which are additionally fixed by mechanical clamps. In this multilayer pack its top part consists of tapered portion and cylindrical portion made of separate sections in the form of a book consisting of two or more mechanically interconnected components where terminating component is fitted with apron with through holes in fabric. In this multilayer pack, resistive components in peripheral zone of current distributing electrodes are located in the array of insulating fibers with interlacing, are cut through alternately on one and on the other side of electric-conducting fiber band. Resistive components together with power electrodes form switching comb of specified resistive component. On tips of power and current-distributing electrodes, tinned foil copper tinned is soldered. Power cords are passed through multilayer pack mass. Each of separate sections along product generatrix are interconnected in series and in parallel by electric connectors.

EFFECT: improvement of operability and operation reliability of multilayer pack for temperature control of complex geometric configuration products.
