(CN217013648-U) NOVELTY - The utility model claims a heating pipe, which is set in the oven, comprising a pipe body, a graphene conductive layer, a conductive lead and an inert gas, the tube body is configured to be transparent material and two sides are closed, forming a containing cavity for containing the graphene conductive layer and the inert gas, the graphene conductive layer is grown on the inner wall of the tube body, and the middle part is connected, the inert gas is filled in the hollow part formed by graphene conductive layer, one end of the conductive lead is connected with the graphene conductive layer, the other end is connected with the power supply. The utility model claims a heating pipe, the electric energy is directly introduced into the graphene conductive layer, using high conductivity and high infrared radiation coefficient of the graphite, which not only can improve the infrared radiation flux in the pipe body, but also can pass through the transparent pipe body to form a high infrared radiation area outside the heating pipe, In this way, the whole heating speed of the heating pipe is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an oven. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the heating pipe. 3Pipe body
