Active carbonization silicon gathers can heating collar

Active carbonization silicon gathers can heating collar comprises one cylindrical set of barrel, and the wall body of cylindrical set of barrel comprises exterior metal shell, combined material insulating layer, carborundum heat-generating body layer, metal heat-conducting layer and high temperature heat conduction coating to interior from outer, is personally experienced sth. Part of the body and is concatenated a plurality of cuboid carborundum resistance wire physically by a plurality of monolithic cuboid carborundum to constitute in carborundum heat-generating body layer, the resistance wire is each internal portion of cuboid carborundum of running through, concatenates formation carborundum heat-generating body layer with cuboid carborundum, the inside of cuboid carborundum is equipped with the several through-hole side by side to a lateral wall of this through-hole forms an open slot with a side surface of cuboid carborundum, the utility model discloses a set up a plurality of monolithic carborundum on the inner wall of cylindrical set of barrel to resistance wire through setting up in it couples together it, through this carborundum come the transition heat can, its electric heat transformation rate reaches more than 98%, does not have any power consumption, and its programming rate is fast.
