A heating belt structure

Abstract

A heating strip structure includes a heat-insulating sleeve and a thermally conductive insulating carrier. The heat-insulating sleeve comprises an insulating base layer wrapped around the outer periphery of the pipeline and a braided layer covering and protecting the insulating base layer to form a composite insulating layer. The braided layer is made of soft insulating wires bonded together to form a braided structure. The thermally conductive insulating carrier is housed within the heat-insulating sleeve and has an insulating protective layer disposed inside the braided layer, and an electric heating element assembly waterproof and insulatingly covered by the insulating protective layer to generate uniform heat within the insulating protective layer and uniformly conduct heat to the heat-insulating sleeve through the insulating protective layer. Through the arrangement of the insulating protective layer of the thermally conductive insulating carrier and the braided layer of the heat-insulating sleeve, the heat-insulating sleeve can be tightly attached to the outer surface of the pipeline. It is also suitable for the surface of pipelines of various diameters and pipeline bends, providing a heat insulation effect to prevent the pipeline from losing heat and effectively reducing energy waste.
