The heat conducting liquid may be a refrigerant, such as freon, or other heat superconducting liquid. Such as superconducting fluids used in radiators. The principle of the heat conduction liquid for quick heat conduction is similar to that of a thermosiphon, a heat pipe and the like. When being heated, the heat-conducting liquid can be rapidly vaporized and rapidly diffused to other areas of the fluid channel 5, and simultaneously, the heat is rapidly transferred to other areas of the inner container, so that the inner container is uniformly heated. During specific manufacturing, the heat-conducting liquid is filled into the fluid channel 5 after a certain vacuum environment is formed in the fluid channel.
