[0003] Existing patent application number: CN202321699973.X An air-conditioning heat exchanger that is easy to replenish water includes a condenser. The beneficial effects of the utility model are: through the filter structure set in the water tank, the water is filtered before entering the condenser, preventing impurities from entering the condenser pipeline, and the threaded rod set to drive the threaded tube to rise and fall can also drive the filter to rise and fall, making it more convenient to facilitate water replenishment operation when cleaning impurities.

[0004] The above patent records a condenser. The structure of the heat exchange tubes in the existing condenser is single. The heat exchange tube structure of the condenser can be improved to enhance the heat exchange efficiency.

DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] See also Figure 1-2 The utility model provides a high-efficiency heat exchange structure of a refrigeration equipment, including a frame 1, a heat exchange tube 2, an auxiliary heat exchange structure 3 and a detachable fin mechanism 4. The heat exchange tube 2 is installed on the inner side of the frame 1, the auxiliary heat exchange structure 3 is arranged on the inner wall of the heat exchange tube 2, and the detachable fin mechanism 4 is arranged on the front of the frame 1.

[0023] See also Figure 3 In the utility model, the auxiliary heat exchange structure 3 includes an inner tube 31 and heat exchange fins 32. The inner tube 31 is embedded inside the straight tube section of the heat exchange tube 2, and the inner wall of the inner tube 31 is integrally provided with heat exchange fins 32. The inner tube 31 can expand the contact area with the refrigerant through the heat exchange fins 32, thereby improving the heat exchange efficiency.

[0024] It is further explained that the number of the heat exchange fins 32 is not less than 3, and the heat exchange fins 32 are concentratedly arranged at the lower middle part of the inner side of the inner tube 31 to ensure that the heat exchange fins 32 can be immersed in the refrigerant for heat exchange contact therewith.

[0025] It is further explained that the inner tube 31 and the heat exchange fins 32 are made of the same overall material as the heat exchange tube 2 to ensure the heat exchange efficiency between them.

[0026] To further explain, a positioning protrusion 33 is integrally provided at the bottom of the inner tube 31, and a positioning groove 34 is opened at the inner bottom of the inner tube 31, wherein the positioning protrusion 33 and the inner side of the positioning groove 34 are mutually inserted, and the installation angle of the inner tube 31 is locked by the cooperation of the positioning protrusion 33 and the positioning groove 34.

[0027] See also Figure 4-5 In the utility model, the detachable fin mechanism 4 includes a front cover 41, a heat dissipation fin group 42 and a pipe hoop 43. The front cover 41 is screwed to the front of the frame 1, and the heat dissipation fin group 42 is installed inside the front cover 41. The rear of the heat dissipation fin group 42 is horizontally welded with a pipe hoop 43, and the heat dissipation fin group 42 is sleeved on the surface of the heat exchange tube 2 through the pipe hoop 43.

[0028] Further explanation: the inner wall of the pipe clamp 43 is paved with a silicone pad 431, the thickness of the silicone pad 431 is not less than 2.5 mm, and the silicone pad 431 can be filled in the gap between the pipe clamp 43 and the heat exchange tube 2 to enhance the heat conduction efficiency.

[0029] Here’s how it works:

[0030] First, the detachable fin mechanism 4 is assembled with the rack 1. The specific operation is: the front cover 41 is placed on the front of the rack 1. During this process, the heat dissipation fin group 42 will be sleeved on the surface of the heat exchange tube 2 through the pipe clamp 43, so that the heat dissipation fin group 42 and the heat exchange tube 2 are assembled. By laying a silicone grease pad 431 on the inner wall of the pipe clamp 43, the silicone grease pad 431 can be filled in the gap between the pipe clamp 43 and the heat exchange tube 2 to enhance the thermal conductivity. Finally, the front cover 41 is fixed to the rack 1 with screws, thereby completing the assembly of the detachable fin mechanism 4 and the rack 1.

[0031] Second, when in use, the refrigerant will exchange heat with the outside air through the heat exchange tube 2, and the heat exchange tube 2 can increase the contact area with the outside air through the heat dissipation fin group 42 to ensure the heat exchange efficiency. In addition, an auxiliary heat exchange structure 3 is provided on the inner wall of the heat exchange tube 2, and an inner tube 31 is embedded on the inner side of the straight tube section of the heat exchange tube 2. The inner tube 31 can expand the contact area with the refrigerant through the heat exchange fins 32, so that the heat can be transferred to the surface of the heat exchange tube 2 through the inner tube 31 more quickly for dissipation, thereby improving the heat exchange efficiency.

[0032] Third, after a period of use, dust is easily accumulated on the surface of the heat sink fin group 42. If it is not cleaned in time, the accumulated dust will increase the thermal resistance of the heat sink fin group 42 and affect the heat exchange efficiency. When the heat sink fin group 42 needs to be cleaned, first remove the screws between the front cover 41 and the frame 1, and then the front cover 41 can be removed together with the heat sink fin group 42, so that the heat sink fin group 42 can be cleaned separately, and the heat sink fin group 42 can be cleaned to ensure the heat exchange efficiency.

[0033] The utility model provides a high-efficiency heat exchange structure of a refrigeration device, by arranging an auxiliary heat exchange structure 3 on the inner wall of a heat exchange tube 2, by embedding an inner tube 31 on the inner side of a straight tube section of the heat exchange tube 2, the inner tube 31 can expand the contact area with the refrigerant through the heat exchange fins 32, so that the heat can be transferred to the surface of the heat exchange tube 2 through the inner tube 31 more quickly to be dissipated, thereby improving the heat exchange efficiency, by arranging a detachable fin mechanism 4 at the front part of the frame 1, by removing the screws between the front cover 41 and the frame 1, the front cover 41 can be disassembled together with the heat dissipation fin group 42, so that the heat dissipation fin group 42 can be cleaned up separately, so as to ensure the heat exchange efficiency.
