Description

Technical Field

[0001] This utility model relates to the technical field of heat exchange components for geothermal wells, specifically a detachable, non-interference geothermal well heat exchange component. Background Technology

[0002] Geothermal heat extraction refers to the technical process of extracting and utilizing heat energy from underground. Its core lies in extracting underground stored heat energy (usually in the form of hot water, steam, or dry hot rock) to the surface through engineering means for power generation, heating, agricultural greenhouses, or other heat energy applications. It often involves setting up heat extraction wells underground, installing heat exchange tube assemblies in the wells, injecting low-temperature working fluid (such as water / CO2) into the heat exchange tube assemblies, and having the working fluid flow through the underground geothermal zone for heat exchange before returning to the surface to release heat energy.

[0003] Currently, many heat exchange components for heat extraction wells on the market have long or integrated pipe bodies. When damage occurs, the entire pipe body needs to be replaced, which is inflexible and increases maintenance and replacement costs.

[0004] Therefore, we proposed a detachable, non-intrusive geothermal well heat exchange component to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to solve the problem that some heat exchange components in current heat extraction wells are mostly long or integrated in shape. When damage occurs, the entire pipe needs to be replaced, which is inflexible and increases maintenance and replacement costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a detachable, non-interference geothermal heat exchange well heat exchange component, comprising: a heat exchange component body, wherein the heat exchange component body includes an extension and a heat exchange part;

[0008] The heat exchange section includes a heat exchange component, and receiving components are symmetrically arranged at both ends of the heat exchange component;

[0009] Connectors are provided on the extension, lower connection end, and heat exchanger.

[0010] Furthermore, the connector includes a connecting ring, which has a plurality of evenly distributed spring cavities. Each spring cavity contains a compression spring and a limiting plate. A locking post is connected to one side of the limiting plate, and a pull line is connected to the other side of the limiting plate. A rotating ring is movably sleeved on the connecting ring. An annular wire groove is formed on the inner ring surface of the rotating ring, and the pull line is connected to the annular wire groove.

[0011] Furthermore, the upper connecting end includes a first pipe body, a first flange is provided at the top of the first pipe body, a first connecting pipe is connected to the bottom of the first pipe body, a first external thread is provided on the surface of the first connecting pipe near the bottom, and a plurality of evenly distributed first locking holes are opened on the surface of the first connecting pipe near the top, the first locking holes being adapted to locking posts.

[0012] Furthermore, the extension includes a second tube body, the inner wall of the second tube body near the top end is provided with a first internal thread, and the bottom end of the second tube body is connected to a second connecting pipe. The surface of the second connecting pipe near the bottom end is provided with a second external thread, and the surface of the second connecting pipe near the top end is provided with a plurality of evenly distributed second locking holes. The first external thread and the second external thread are both adapted to the first internal thread, and the second locking holes are adapted to the locking posts.

[0013] Furthermore, the lower connecting end includes a third pipe body, the inner wall of the third pipe body near the top is provided with a second internal thread, and the bottom end of the third pipe body is provided with a second flange, the second internal thread being compatible with the second external thread.

[0014] Furthermore, the receiving component includes an L-shaped tube body, one end of which is provided with a third flange, and the other end of which is provided with a third connecting pipe.

[0016] Furthermore, connecting bolts and nuts are provided between the second flange and the third flange, and the lower connecting end is connected and fixed to the receiving part through the cooperation of the second flange and the third flange, as well as the connecting bolts and nuts.

[0017] The beneficial effects of this utility model are as follows: By dividing the main body of the heat exchange component into an extension part and a heat exchange part, the extension part is divided into an upper connecting end and a lower connecting end, as well as multiple extension parts. The upper connecting end, the lower connecting end, and the multiple extension parts are connected by connectors and threaded connections. The heat exchange part is divided into a heat exchange component and a receiving component.
