[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0024] The following is a further detailed description of the present application in conjunction with the attached Figure 1-6 to further illustrate the present application in detail,

[0025] The embodiments of the present application disclose a heat exchanger in a medium-deep geothermal heat exchange well with waterproof and anticorrosion properties. Referring to Figure 1 、 Figure 3 、 Figure 4 and Figure 5 , a heat exchanger in a medium-deep geothermal heat exchange well with waterproof and anticorrosion properties includes an appliance body 1. The appliance body 1 includes an outer shell 101. A support plate 103 is fixedly connected to the inner cavity of the outer shell 101. A heat exchange tube 102 is fixedly connected to the inner cavity of the support plate 103. Sealing mechanisms 2 are installed on both sides of the outer shell 101;

[0026] The sealing mechanism 2 includes a sealing frame 202 and a sealing ring 204. One side of the sealing frame 202 is movably connected to the surface of the outer shell 101, and one side of the sealing ring 204 is fixedly connected to the surface of the outer shell 101. An air outlet 201 communicates with one side of the sealing frame 202, and an air inlet 203 communicates with the other side of the sealing frame 202. The inner cavity of the sealing frame 202 is in close fit with the surface of the sealing ring 204. Sealing gaskets 210 are fixedly connected to both the top and bottom of the inner cavity of the sealing frame 202.

[0027] Referring to Figure 3 and Figure 5 , a positioning groove 205 is provided in the inner cavity of the sealing ring 204. A positioning plate 209 is inserted into the inner cavity of the positioning groove 205. One side of the positioning plate 209 is fixedly connected to the inner cavity of the sealing frame 202. Through the setting of the positioning groove 205, the positioning plate 209 can enter the inside of the sealing ring 204, thereby playing a positioning role for the sealing frame 202 and enabling it to stably fit on the surface of the sealing ring 204.

[0028] Referring to Figure 4 , a connecting block 208 is fixedly connected to one side of the sealing frame 202. A connecting plate 207 is inserted into the inner cavity of the connecting block 208. One side of the connecting plate 207 is fixedly connected to the surface of the sealing frame 202. Through the setting of the connecting plate 207, when it is inserted into the inside of the connecting block 208, it can play a role in fixing the positions between the sealing frames 202, thereby strengthening the connection sealing performance between the sealing frames 202.

[0029] Referring to Figure 1 and Figure 4 , bolts 206 are threadedly connected to the inner cavity of the sealing frame 202. The number of bolts 206 is multiple and they are distributed in a ring shape. The surface of the bolts 206 is threadedly connected to the inner cavity of the sealing frame 202. Through the setting of the bolts 206, it plays a role in fixing the position between the sealing frame 202 and the outer shell 101, preventing the sealing frame 202 from detaching from the surface of the outer shell 101 during use.

[0030] Referring to Figure 1 and Figure 2, a fixing mechanism 3 is mounted on the surface of the outer shell 101. The fixing mechanism 3 includes a support base 302. The inner cavity of the support base 302 is movably connected to the surface of the outer shell 101. The bottom of the support base 302 is fixedly connected to a base 301. The front side of the support base 302 is fixedly connected to a fixing base 304. A fixing shaft 303 is fixedly connected to the inner cavity of the fixing base 304. A movable plate 305 is movably connected to the surface of the fixing shaft 303. A fixing plate 306 is fixedly connected to the back side of the movable plate 305. The inner cavity of the fixing plate 306 is in close fit with the surface of the outer shell 101. Through the setting of the support base 302, the position of the outer shell 101 is supported. And through the setting of the fixing plate 306, the surface of the outer shell 101 can be clamped, so that it can be stably placed on the surface of the support base 302.

[0031] Refer to Figure 2 , a plugging slot 308 is opened at the top of the inner cavity of the support base 302. A plugging plate 307 is plugged and connected to the inner cavity of the plugging slot 308. The top of the plugging plate 307 is fixedly connected to the bottom of the fixing plate 306. Through the setting of the plugging slot 308, the plugging plate 307 can be plugged into the inside of the support base 302. Thus, when the outer shell 101 is clamped on the surface of the fixing plate 306, the position of the fixing plate 306 can be fixed to prevent the inner side of the fixing plate 306 from separating from the surface of the outer shell 101.

[0032] Refer to Figure 1 and Figure 6 , an anti-corrosion coating 105 is attached to the surface of the outer shell 101. A waterproof coating 104 is attached to the surface of the anti-corrosion coating 105. The anti-corrosion coating 105 is epoxy resin, and the waterproof coating 104 is polymer cement-based. Through the settings of the waterproof coating 104 and the anti-corrosion coating 105, the surface of the outer shell 101 is protected. The waterproof coating 104 prevents geothermal water from entering the inside of the outer shell 101, and the anti-corrosion coating 105 prevents the geothermal water from corroding the surface of the outer shell 101.

[0033] Working principle: First, place the outer shell 101 on the top of the support base 302. Rotate by holding the fixing plate 306. The rotation of the fixing plate 306 drives the movable plate 305 to rotate on the surface of the fixed shaft 303 until the inner side of the fixing plate 306 fits against the surface of the outer shell 101, thereby clamping the position of the outer shell 101 so that it can be stably placed on the top of the support base 302. And during the movement of the fixing plate 306, the plug-in plate 307 will be driven to move. When the fixing plate 306 is in place, the surface of the plug-in plate 307 will be inserted into the inside of the plug-in slot 308, thereby fixing the position of the fixing plate 306 and preventing the inner side of the fixing plate 306 from separating from the surface of the outer shell 101. Then, move by holding the sealing frame 202 and attach the sealing frame 202 to the surface of the sealing ring 204. During the movement of the sealing frame 202, the positioning plate 209 will be driven to move. When the sealing frame 202 is in place, the surface of the positioning plate 209 will be inserted into the inside of the positioning slot 205, so that the sealing frame 202 can be stably attached to the surface of the sealing ring 204. At the same time, the movement of the sealing frame 202 will drive the connecting plate 207 to move until the surface of the connecting plate 207 is inserted into the inside of the connecting block 208, which can fix the position between the sealing frames 202. And during the movement of the sealing frame 202, the sealing gasket 210 will be driven to move synchronously, thereby improving the sealing effect at the connection of the sealing frame 202. Finally, insert the bolt 206 into the inside of the sealing frame 202 and the outer shell 101 to fix the position between the sealing frame 202 and the outer shell 101, thereby preventing the sealing frame 202 from detaching from the surface of the outer shell 101 during use.

[0034] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
