FIELD: heating. ^ SUBSTANCE: metal tube (1) is out on metallic string, to bottom end of which there are connected leads of spiral of heating element (4). To the middle of spiral it is suspended hook end with chuck. It is pulled down tube (1) on spiral and fixed on chuck. Tube (1) with spiral is unhooked from string, is installed into spring-loaded funnel of charging equipment. There are fixed in installation leads (5) spirals are put on branched of spiral two bushings, through which it is filled electro-insulating filler. As far as filling by filler (3) tubes (1), of cartridge case from it is lead out. Filled tube (1) is pressed and fixed to it bottom (2). ^ EFFECT: excluding short circuits in tubular electric heating unit and improvement of heat transfer from spiral to metallic tube. ^ 3 dwg |
