NOVELTY - The utility model claims a underfloor heating pipe, comprising a floor heating pipe main body, the floor heating pipe main body comprises an inner layer, the outer side of the inner layer is fixedly connected with a reinforcing layer, the inner part of the reinforcing layer is provided with a grid filament, the outer side of the reinforcing layer is fixedly connected with a spring, one end of the spring far away from the reinforcing layer is fixedly connected with an outer layer, the outer side surface of the outer layer is fixedly connected with a heat conducting ring, the floor heating pipe main body is S-shaped set to form a underfloor heating pipe, the material used by the inner layer and the outer layer is PEX, the material used by the reinforcing layer is a graphene The heat conducting ring is formed by bending the graphite sheet. Through said structure, using the elastic performance of the spring to avoid the heat expansion of the geothermal pipe to make the geothermal pipe, damage the same time, using the reinforcing layer can avoid the phenomenon of the pipeline, damage the firmness of the pipeline, and then through the heat conducting ring can quickly and uniformly lead the heat of the geothermal pipe out of the pipe body, and the heating effect of the geothermal pipe is enhanced.
