Problems solved by technology

Although this method is simple and easy to implement, the heat conduction resistance of the tube wall between the inner and outer flow channels is still not large enough; the second is to set up an interlayer on the inner tube wall of the casing, and vacuumize the interlayer to isolate the fluid in t

Abstract

The invention discloses a middle-deep layer sleeving type geothermal heat exchanger device containing a radiation insulation film. The device is formed by connecting a plurality of sections of sleeving type geothermal heat exchangers. A single section of sleeving type geothermal heat exchanger comprises an inner tube and an outer tube, a vacuum insulation interlayer is arranged on the tube wall ofthe inner tube, and a layer of an annular radiation insulation film coaxial with the inner tube is arranged inside the vacuum insulation interlayer. The inner and outer tubes of two adjacent sectionsof heat exchangers are all connected in a welding mode. The radiation heat insulation film is arranged in the middle position of the vacuum insulation interlayer. Through the arrangement that the vacuum insulation interlayer containing the radiation heat insulation film is added in the tube wall of the inner tube of the middle-deep layer sleeving type geothermal heat exchanger, the heat radiationcapacity between the two wall faces of the interlayer in the tube wall and between inner and outer flow channels is effectively reduced, "thermal short circuit" between the inner and outer flow channels of the sleeving is reduced, and the heat extraction efficiency of the middle-deep layer sleeving type geothermal heat exchanger is improved.

Description

technical field [0001] The invention relates to a casing type mid-deep geothermal heat exchanger technology, in particular to a mid-deep casing type geothermal heat exchanger device with a radiation insulation film. Background technique [0002] In recent years, due to the needs of energy development, environmental governance, and improvement of people's livelihood, geothermal energy heating technology is facing a major development opportunity, and its application ratio in the heating industry is increasing. Buried pipe ground source heat pump is the most widely used technology in geothermal heating. According to the depth of buried pipes, ground source heat pumps with buried pipes can be divided into ground source heat pumps with shallow buried pipes and ground source heat pumps with medium and deep buried pipes. Among them, the ground source heat pump with medium and deep buried pipes has just emerged in my country in recent years. Its underground heat exchanger has a bur...
