1. A thermal conductive cylinder for being installed within a thermal storage body (500) composed of a natural thermal storage body, the natural thermal storage body including one of a shallow surface of the earth, a body of water, and artificial objects in a solid, gaseous, or liquid state;
wherein the thermal conductive cylinder is installed with a plurality of U-type core piping (100) and constructed so that a thermal insulation (400) is present between a fluid inlet terminal and a fluid outlet terminal of each of the plurality of U-type piping (100) so as to prevent thermal energy loss because of thermal conduction between adjacent piping segments of the inlet terminal and the outlet terminal on a same side when thermal conductive fluid with a temperature difference passes through; wherein each of the plurality of U-type piping (100) is used for one or more of the following types of thermal conductive fluid (111) passing through, including: 1) liquid state fluid; 2) gaseous state fluid; 3) liquid to gaseous state fluid; and 4) gaseous to liquid state fluid, wherein two or more radially arranged sections of the U-type piping are installed within the thermal conductive cylinder and the two or more radially arranged U-type piping sections are discrete from and have interior flowpaths that are not in communication with each other within the thermal conductive cylinder; and wherein main components of the thermal conductive cylinder are as follows:
the plurality of U-type piping (100): each made of a U-type tubular body for the thermal conductive fluid (111) to pass through, wherein the plurality of U-type piping (100) is installed within a columnar thermal conductive body (300) composed of solid state or colloidal object; each of the U-type piping (100) has a separate first fluid inlet and outlet terminal (101) and a separate second fluid inlet and outlet terminal (102), the piping segments near the first fluid inlet and outlet terminal (101) are adjacently installed at the axial core of the columnar thermal conductive body (300), and the piping segments near the second fluid inlet and outlet terminal (102) are radially arranged along an axial direction and near an edge of the columnar thermal conductive body (300);the columnar thermal conductive body (300): made of thermal conductive material, wherein the columnar thermal conductive body (300) has a columnar structure with various geometric shape sections, for coating the U-type piping (100) and a thermal insulating device (400); andthe thermal insulating device (400): made of a thermal insulating structure with thermal insulating effects, the thermal insulating structure including one of a solid body, a flexible body, a foam body, and an enveloped colloid, gas, liquid, or vacuum structure, for being placed between the piping segments near the first fluid inlet and outlet terminal (101) of each of the U-type piping (100) that are adjacently installed at the axial core of the columnar thermal conductive body (300), and the piping segments near the second fluid inlet and outlet terminal (102) of each of the U-type piping; for substantially reducing thermal energy loss caused by thermal conduction between adjacent piping segments of the first fluid inlet and outlet terminal (101) and the second fluid inlet and outlet terminal (102) on the same side of the U-type piping (100). |
