[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Embodiment 1: The present invention solves the problem that the existing heat exchange tubes generate high temperatures during use, and the elastic clamps are elastically engaged, and the high temperature may cause the elastic clamps to melt, thereby causing the heat exchange tubes and the heat exchanger to separate. The slider 5 can achieve the purpose of rapid disassembly and assembly, and discloses:

[0032] The heat exchange tube body 1 has a connecting tube 2 attached to its bottom. Furthermore, a latch 3 is passed through the top of the connecting tube 2, and the top of the latch 3 extends into the interior of the groove 4 to form a sliding mechanism. The top of the latch 3 passes through the airbag 14, and a slider 5 is fixed to the top of the latch 3. The outer end of the slider 5 extends into the interior of the slide groove 6 to form a locking mechanism. The slide groove 6 is provided inside the heat exchange tube body 1.

[0033] refer to Figures 1 to 5 When the ground source heat pump heat exchanger is in use, the refrigerant in the heat exchange tube body 1 absorbs the heat inside the ground source heat pump heat exchanger and evaporates into gas, which is then pressurized by the compressor to become high-temperature and high-pressure gas. The high-temperature gas enters the condenser and exchanges heat with water in the heat exchange tube body 1. When the heat exchange tube body 1 needs to be replaced and maintained, the latch 3 is rotated to drive the slider 5 to rotate, and then the latch 3 can slide inside the groove 4, and the slider 5 will slide inside the slide groove 6. After the latch 3 is rotated to the position, the slider 5 rotates to disengage the slide groove 6, and then the latch 3 is pulled, and then the latch 3 can be disengaged from the groove 4, and the latch 3 drives the slider 5 to disengage the slide groove 6, so that the heat exchange tube body 1 and the connecting pipe 2 can be separated, thereby achieving the purpose of convenient replacement and preventing the connection from being unstable due to high temperature.

[0034] Embodiment 2: The present invention solves the problem of unstable engagement between the slider 5 and the chute 6 in embodiment 1. The protrusion 7 can improve the stability of engagement between the slider 5 and the chute 6.

[0035] The slider 5 is slidably connected to a protrusion 7, and the outer end of the protrusion 7 is semicircular. The outer end of the protrusion 7 extends into the interior of the card slot 8 to form a locking mechanism. The card slot 8 is provided inside the heat exchange tube body 1. The inner end of the protrusion 7 is connected to a first spring 9, and the inner end of the first spring 9 is connected to the interior of the slider 5.

[0036] refer to Figure 1 and Figure 5 The rotation of the slider 5 drives the protrusion 7 to rotate, and then the protrusion 7 rotates and squeezes the slot 8, so that the protrusion 7 is squeezed to slide toward the inside of the slider 5, and the movement of the protrusion 7 squeezes the first spring 9, so that the first spring 9 is compressed, and then the movement of the protrusion 7 will disengage from the engagement with the slot 8, thereby facilitating the sliding of the slider 5 inside the slide groove 6. The force of the first spring 9 will push the protrusion 7 into the interior of the slot 8 for engagement, thereby improving the stability of the engagement between the slider 5 and the slide groove 6;

[0037] Example 3: This utility model solves the problem that there is a gap between the existing heat exchange tube body 1 and the connecting tube 2, which leads to weak sealing. The airbag 14 can improve the sealing. The following is disclosed:

[0038] The top of the latch 3 is fitted with a push plate 10, and the push plate 10 slides inside the heat exchange tube body 1, and the top of the push plate 10 extends into the interior of the gas storage tank 11 to form a sealed sliding mechanism, and the gas storage tank 11 is nested inside the heat exchange tube body 1, and the gas storage tank 11 stores gas, and the top of the gas storage tank 11 is connected to the air pipe 13, and the bottom of the air pipe 13 is connected to the top of the air bag 14, and the air bag 14 is fitted to the bottom of the heat exchange tube body 1, and the air pipe 13 is nested inside the heat exchange tube body 1, and the top of the push plate 10 is connected to the second spring 12, and the top of the second spring 12 is connected to the inside of the gas storage tank 11;

[0039] refer to Figure 3 、 Figure 5 and Figure 6 The movement of the latch 3 will squeeze the push plate 10, so that the push plate 10 moves and extends into the interior of the gas storage tank 11, so that the gas inside the gas storage tank 11 is squeezed and transported to the interior of the air pipe 13, and then the gas is transported to the interior of the air bag 14 through the air pipe 13, and the movement of the push plate 10 will squeeze the second spring 12, so that the second spring 12 is compressed, and then the air bag 14 can expand, so that the gap between the heat exchange tube body 1 and the connecting tube 2 is sealed, thereby improving the sealing performance, and after the latch 3 is released from the squeezing of the push plate 10, the second spring 12 can push the push plate 10 to reset, so that negative pressure will be generated inside the gas storage tank 11, and then the negative pressure can allow the air in the air bag 14 to enter the interior of the gas storage tank 11 through the air pipe 13 for storage.

[0040] Working principle: When using this kind of ground source heat pump heat exchanger heat exchanger tube, first, refer to Figures 1 to 5When the ground source heat pump heat exchanger is in use, the refrigerant in the heat exchange tube body 1 absorbs the heat inside the ground source heat pump heat exchanger and evaporates into gas, which is then pressurized by the compressor to become high-temperature and high-pressure gas. The high-temperature gas enters the condenser and exchanges heat with water in the heat exchange tube body 1. When the heat exchange tube body 1 needs to be replaced and maintained, the latch 3 is rotated, and the slider 5 slides inside the chute 6. After the latch 3 is rotated to the position, the slider 5 rotates to disengage the chute 6, thereby achieving the purpose of convenient replacement and preventing the connection from being unstable due to high temperature.

[0041] refer to Figure 1 and Figure 5 The rotation of the slider 5 drives the protrusion 7 to rotate, and then the protrusion 7 rotates and squeezes the slot 8. Then the protrusion 7 moves to disengage from the slot 8, thereby facilitating the sliding of the slider 5 inside the slot 6. The force of the first spring 9 pushes the protrusion 7 into the slot 8 for engagement, thereby improving the stability of the engagement between the slider 5 and the slot 6.

[0042] refer to Figure 3 、 Figure 5 and Figure 6 The movement of the latch 3 will squeeze the push plate 10, so that the push plate 10 moves and extends into the interior of the gas storage tank 11, and then the gas is transported to the interior of the air bag 14 through the air pipe 13, and then the air bag 14 can expand, so that the gap between the heat exchange tube body 1 and the connecting pipe 2 can be sealed, thereby improving the sealing performance, and after the latch 3 is released from the squeezing of the push plate 10, the second spring 12 can push the push plate 10 to reset, and then the negative pressure can allow the air in the air bag 14 to enter the interior of the gas storage tank 11 through the air pipe 13 for storage.
