Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0020] ginseng figure 1 , to introduce a specific embodiment of the buried heat exchange tube of the present invention. In this embodiment, the buried heat exchange tube 20 includes a heat exchange portion 21 and a gravity portion 22 .

[0021] The heat exchange part 21 is in the shape of a spring. By setting the heat exchange part 21 into a coiled spring shape, after installation, the heat exchange part 21 can extend a longer pipe length in the same depth of drilling, so as to obtain a greater connection with the surrounding soil. A larger heat exchange area improves heat exchange efficiency. Corres...

Abstract

The invention discloses a ground buried heat exchange pipe and a ground buried pipe type heat exchanger, wherein the ground buried pipe type heat exchanger comprises a heat exchange pipe main body and a ground buried heat exchange pipe, the ground buried heat exchange pipe comprises a heat exchange part, the heat exchange part comprises a first end connected with the heat exchange pipe main body and a second end opposite to the first end, and the heat exchange part of the ground buried heat exchange pipe is in a spring shape. The ground buried pipe type heat exchanger adopting the ground buried heat exchange pipe provided by the invention has the advantages that the heat exchange part of the ground buried heat exchange pipe is made into a spring shape, the longer pipeline length can be obtained through extending in drilling wells with the same depth, more heat exchange areas with the soil can be obtained, the heat exchange efficiency is improved, and the construction difficulty is reduced.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, and in particular relates to a buried heat exchange tube and a buried tube heat exchanger with the buried heat exchange tube. Background technique [0002] The vertical buried pipe ground source heat pump technology is a renewable energy technology, which utilizes the characteristics of soil temperature stability throughout the year. In winter, the soil energy can be used as a heat source for heat pump heating, and in summer, the soil energy can be used as a cold source for air conditioning. At present, the vertical buried pipe ground source heat pump technology has been widely used in the construction field, which has the following advantages: high efficiency, the temperature of the soil is higher than the ambient temperature in winter, and lower than the ambient temperature in summer, making the ground source heat pump and the traditional air conditioning system Compared with winter, it i...
