[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 8 As shown: This embodiment provides a shallow geothermal energy exchange device, including an anchoring core structure 1 and a heat exchange tube fixing plate 3 that passes through and is fixedly connected to the anchoring core structure. Multiple heat exchange tubes 2 are circumferentially and fixedly installed on the outer wall of the heat exchange tube fixing plate. In this embodiment, the anchoring core structure includes multiple anchors 1-1 and an anchor support 1-2 that integrates and fixes the multiple anchors together.

[0028] Multiple support ribs 4 are inserted and fixed on the heat exchange tube fixing plate, and the heat exchange tube is tied and fixed to the support ribs; multiple through holes 3-3 are opened on the heat exchange tube fixing plate, which are inserted and fixed one-to-one with the support ribs.

[0029] The inner sidewall of the heat exchange tube fixing plate is provided with a plurality of anchor slots 3-2 that are spaced apart and correspond one-to-one with the anchors; the outer sidewall of the heat exchange tube fixing plate is provided with a plurality of heat exchange tube slots 3-1 that are spaced apart and correspond one-to-one with the heat exchange tubes.

[0030] It also includes grouting pipes 1-3, and the anchor bracket has through holes for the grouting pipes.

[0031] The following is further explanation:

[0032] The anchors can be anchor rods, anchor cables, etc. Several heat exchange tube fixing plates are set according to the design length of the anchors. Generally, one set can be laid every 1500mm-2000mm. The anchors pass through the hollow part of the heat exchange tube fixing plate and are locked one-to-one by the anchor slots 3-2. The connection reliability between the anchors and the heat exchange tube fixing plates can be enhanced by binding.

[0033] The support ribs 4 pass through the through holes 3-3 one-to-one and are inserted and fixed to the heat exchange tube fixing plate. An interference fit can be used for fixing. The support ribs 4 are generally matched to the pipe laying method of the heat exchange tubes 2, and several ribs are installed. The support ribs 4 and the heat exchange tube fixing plate 3 form a layout framework, and the heat exchange tubes 2 are connected to the support ribs 4 to form a predetermined layout. For example... Figure 1 The straight pipe layout shown is as follows: Figure 7The spiral arrangement is shown around the anchoring core structure; Figure 8 The spiral arrangement is shown around the frame stud.

[0034] The heat exchange pipe 2 is clamped and fixed by the heat exchange pipe clamping groove 3-1, and is tied and connected with the frame stud 4 to realize stability.

[0035] During construction, the frame stud 4 can be additionally arranged according to the layout situation of the heat exchange pipe, and the heat exchange pipe 2 is tied and fixed into a preset layout type with the frame stud 4. The heat energy exchange device is integrally manufactured with the anchoring core structure, is lowered after drilling is completed, and then the grouting process of the anchoring member is completed through the grouting pipe. After the curing period is completed, the completed integrated anchor body can meet the support requirements or anti-floating effect of the project, and can be connected with the air conditioning system in the later period to realize heat exchange of the air conditioning system.
