MULTILAYER STACK FOR THERMOSTATIC CONTROL OF COMPLEX-GEOMETRY PARTS Russian patent published in 2004 - IPC

FIELD: electrothermy for rocket building to heat various rocket parts, domestic appliances, medicine, agriculture, and other industries. SUBSTANCE: multilayer stack designed for temperature control of complexgeometry parts has external and internal shielding layers with heat-insulating spacers in-between and conducting strips with insulating layers joined at ends with aid of conducting jumpers; conducting strips are made in the form linen-weave filler composed of four sets of yarns of which three ones are longitudinal sets in the form of insulating-thread strips, current- distributing and current-carrying metallized tinsel threads, and fourth one that crosses them and is disposed perpendicular to them; it is assembled of complex electricity conducting heat-transfer polymeric threads made of polyamide capron fibers whose outer surfaces are covered with continuous composite conducting coating based on tetrafluoroethylene and vinylidene fluoride copolymer. Conducting jumper is made of molded composite insulating material copper or brass foil clad on both sides. Supporting ring can be made of a number of segments joined together. EFFECT: enhanced reliability and serviceability of parts subjected to thermostatic control in various industries. 4 cl, 11 dwg, 1 tbl
