[0002] With the improvement of global environmental protection awareness and the continuous improvement of energy efficiency requirements, the field of refrigeration technology is also developing towards a more environmentally-friendly, efficient and sustainable direction. Traditional refrigeration equipment mostly uses chlorofluorocarbon refrigerants such as freon, which has caused serious damage to the ozone layer and has a great impact on global climate change. With the gradual popularization of natural refrigerants, refrigeration equipment using natural gases such as carbon dioxide and ammonia as refrigerants has become a new research hotspot. Natural refrigerants not only have good heat exchange performance, but also do not pollute the environment, meeting the global demand for low-carbon environmental protection.

[0044] Embodiment 3

[0045] As shown in Figures 1-7 The end of the clamping plate 25 away from the transport pipe 28 is provided with an exchange mechanism 3, which includes a protective plate 31. One end of the protective plate 31 is provided with a connecting pipe 32. One side of the protective plate 31 is provided with a clamping wall 36. The clamping wall 36 is provided with a butt joint rivet 33. The outer surface of the butt joint rivet 33 is provided with a heat preservation sleeve cotton 35. The butt joint rivet 33 is provided with an exchange box 34. Two exchange boxes 34 are provided with a partition embedded sheet 37. One side of the partition embedded sheet 37 is provided with a protective box sleeve 38. The protective box sleeve 38 is provided with a double-temperature preparation bin 39.

[0046] One end of the connecting pipe 32 is butt jointed to the exchange box 34. The other end of the connecting pipe 32 is butt jointed to the butt joint pipe ring 27 on the clamping plate 25. Five groups of partition embedded sheets 37, protective box sleeves 38 and double-temperature preparation bins 39 are clamped between the two exchange boxes 34. The outer surface of the double-temperature preparation bin 39 is nested in the protective box sleeve 38. One side of the partition embedded sheet 37 is attached to one side of the protective box sleeve 38. The butt joint rivet 33 passes through the clamping wall 36 to assemble the exchange box 34, the partition embedded sheet 37, the protective box sleeve 38 and the double-temperature preparation bin 39. The inner surface of the heat preservation sleeve cotton 35 is nested on the outer surface of the butt joint rivet 33. The protective plate 31 is attached to the outer surface of the exchange box 34.

[0047] In this embodiment, in order to make it practical in actual use, therefore, the corresponding exchange mechanism 3 is arranged at the end of the refrigerant mechanism 2 away from the refrigeration mechanism 1, and the staff can introduce the cooling liquid used in the refrigerant mechanism 2 into the exchange mechanism 3 by using the connecting pipe 32, and the protection plate 31 can more perfectly protect the exchange box 34 in actual use, and the cooling liquid entering the exchange mechanism 3 will enter the exchange box 34 through the connecting pipe 32, and the heat preservation sleeve cotton 35 can protect the butt rivet 33 in actual use, so that it can more stably carry out refrigeration in actual use, and the clamping wall 36 can assemble and fix the exchange mechanism 3 in actual use, and the cooling liquid in the exchange box 34 will be cooled by the cooling liquid in the partition plate insert 37, the protection box sleeve 38 and the double-temperature preparation bin 39, so that it can more stably carry out refrigerant refrigeration cycle use in actual use, so that its practicality in actual use is further improved.

[0048] Working principle:

[0049] As shown in Figures 1-7 , when using the refrigeration equipment to carry out refrigeration, the staff first introduces the cooling liquid to be cooled into the refrigeration device 14 through the suction pipe 16, and starts the refrigeration process. The staff can accurately control the opening and closing of the extraction pipe 18 by operating the control valve 19, and ensure that only the required refrigeration liquid is extracted. At the same time, the staff can monitor the working state of the refrigeration device 14 by checking the report lamp 15, so as to ensure the smooth progress of the refrigeration process. This design greatly improves the convenience and operability of the equipment in actual use.

[0050] In order to realize refrigeration cycle, one end of the exhaust pipe 17 is connected with the refrigeration device 14, and the used refrigeration liquid is discharged through the exhaust pipe 17 and recycled, so as to ensure the efficient and stable operation of the equipment. Through this closed loop design, the refrigeration process can continue, and resource waste is avoided.

[0051] The management of refrigerant is also very important. When in use, the staff will place the refrigerant in the refrigerant mechanism 2, and the refrigerant fins 24 will start to dissipate heat after the natural cooling effect provided by the refrigerant. The refrigerant fins 24 are connected in groups by the clamping device 23, and the clamping device 23 is installed on the connecting frame rod 22, so as to ensure the maximization of the refrigeration effect and improve the overall refrigeration performance. The clamping plate 25 limits the refrigerant fins 24 through the installation rivet 26, so as to ensure that they will not be loose or deviated during work, and at the same time, the stability of the cooling effect is guaranteed.

[0052] To ensure the effective flow of refrigerant liquid in the system, the outer surface of the transport pipe 28 is ingeniously interspersed through the refrigerant fins 24 and is docked with the docking pipe ring 27 to form a flow channel. At the far end of the refrigeration device, an exchange mechanism 3 is provided, which can further improve the heat exchange efficiency of the system. The working personnel introduces the cooling liquid into the exchange mechanism 3 through the connecting pipe 32, ensuring the efficient transfer and reuse of the cooling liquid after each use of the system.

[0053] To further enhance the safety and stability of the system, the protective plate 31 can provide protection for the exchange box 34 during use to prevent damage caused by external factors. The cooling liquid entering the exchange mechanism 3 passes through the connecting pipe 32 into the exchange box 34 and is protected by the heat preservation sleeve cotton 35 against the docking rivet 33, ensuring that the components of the system are not affected by the external environment and maintaining the stability of the refrigeration effect.

[0054] In the exchange box 34, the cooling liquid passes through the partition insert 37, the protective box sleeve 38, and enters the double-temperature preparation bin 39 for cooling and recycling. Through these ingenious designs, the refrigeration effect of the refrigerant is more stable, effectively improving the refrigeration efficiency and circulation performance of the entire device

[0055] The clamping wall 36 ensures the assembly and fixation of the exchange mechanism 3, ensuring the stability of the device during operation. All these designs make the refrigeration device more efficient and stable in actual use, can adapt to different working environments, improve the comprehensive applicability and durability of the device, and further prolong the service life of the device.
