Description

Technical Field

[0001] This utility model relates to the technical field, and more specifically to an intelligent temperature-controlled self-cleaning high-efficiency heat exchange tube for air conditioning. Background Technology

[0002] Traditional air conditioning heat exchange tubes mostly use smooth copper tubes, whose heat transfer efficiency is limited by the low turbulence on the tube wall surface and the limited heat exchange area. To improve performance, the industry has successively developed heat transfer enhancement technologies such as internally threaded tubes and microfinned tubes, which increase the boiling / condensation heat transfer coefficient on the refrigerant side by increasing the roughness of the inner surface or expanding the surface area. However, with the continuous upgrading of air conditioning energy efficiency standards (such as SEER and APF) and the promotion and application of environmentally friendly refrigerants (such as R32 and R290), existing heat exchange tubes face challenges in terms of working fluid compatibility, pressure drop control, and long-term fouling resistance.

[0003] Existing heat exchange tubes can control the heat exchange temperature by adjusting the temperature according to actual needs. However, during use, the number of heat exchange tubes in the longitudinal direction and the width of adjacent heat exchange tubes need to be adjusted according to the size and model of the air conditioner. Therefore, different sizes of air conditioners require different heat exchange tubes, and it is inconvenient to replace the heat exchange tubes after they are damaged, which makes it inconvenient for users to maintain. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides an intelligent temperature-controlled self-cleaning air conditioning high-efficiency heat exchange tube to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a smart temperature-controlled self-cleaning air conditioner high-efficiency heat exchange tube, including a heat exchange tube assembly, an adjustment component installed on one side of the heat exchange tube assembly, a telescopic tube assembly installed on the outside of the adjustment component, the heat exchange tube assembly including a heat exchange tube body, a connecting elbow fixedly connected to the front and back of the heat exchange tube body, a first flange fixedly connected to the side of the connecting elbow away from the heat exchange tube body, and a bolt positioning hole opened on the side of the first flange.

[0006] Furthermore, the adjustment assembly includes a first adjustment plate, a first positioning sleeve fixedly connected to one side of the first adjustment plate, a first positioning bolt installed on the top of the first adjustment plate, a first arc surface installed on the other side of the bottom of the first adjustment plate, a convex sliding groove formed at the bottom of the first adjustment plate, a convex sliding strip provided on the inner side of the convex sliding groove, a second adjustment plate fixedly connected to the bottom of the convex sliding strip, a second arc surface formed on one side of the second adjustment plate, and a second positioning sleeve fixedly connected to the other side of the second adjustment plate.

[0007] Furthermore, the telescopic tube assembly includes a positioning ring, a second flange is fixedly connected to the outer side of the positioning ring, a second positioning bolt is installed on the side of the second flange, and the telescopic tube body is fixedly connected to the side of the positioning ring.

[0008] Furthermore, the diameter of the bolt positioning hole and the diameter of the second positioning bolt are matched, and the diameter of the positioning ring is the same as the diameter of the heat exchange tube body.

[0009] Furthermore, the diameter of the first positioning sleeve is clearance-fitted with the diameter of the heat exchange tube body, the thickness of the first adjusting plate is half the diameter of the first positioning sleeve, and the thickness of the second adjusting plate is the same as the thickness of the first adjusting plate.

[0010] Furthermore, the diameter of the second arc surface is the same as the diameter of the outer side of the first positioning sleeve, the diameter of the outer side of the first arc surface is the same as the diameter of the outer side of the second positioning sleeve, and the diameter of the second arc surface is the same as that of the first positioning sleeve.

[0011] Furthermore, the cross-sectional dimensions of the convex sliding groove and the cross-sectional dimensions of the convex sliding strip are fitted with a clearance, and the first positioning bolt is located at the middle of the longitudinal direction of the top of the first adjusting plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. When it is necessary to adjust the spacing between heat exchanger tube assemblies, the present invention first removes the first positioning bolt, and then adjusts the distance between the second flanges by adjusting the extension and retraction of the telescopic tube body. This allows the convex sliding strip and the second adjusting plate to slide inside the convex sliding groove, thereby causing the first adjusting plate and the second adjusting plate to be misaligned. Then, the distance between the first positioning sleeve and the second positioning sleeve is adjusted, and then the distance between the two heat exchanger tube bodies is adjusted. This allows the system to adapt to different air conditioner signals by adjusting the number and spacing of the heat exchanger tube assemblies when installed on different models of air conditioners.

[0014] 2. When a section of the heat exchange tube is damaged, the second positioning bolt can be removed to completely separate the first and second adjusting plates. Then, the telescopic tube assembly or the heat exchange tube assembly can be replaced. The adjusting assembly can be installed in its original position to achieve single-section replacement, which is convenient for maintenance personnel to perform maintenance work on the heat exchange tube.

This allows the convex sliding strip 206 and the second adjusting plate 208 to slide inside the convex sliding groove 207, thus causing the first adjusting plate 201 and the second adjusting plate 208 to be misaligned. Then, the distance between the first positioning sleeve 202 and the second positioning sleeve 209 is adjusted, and then the distance between the two heat exchange tube bodies 101 is adjusted.

A second adjusting plate 208 is fixedly connected to the bottom of the convex sliding strip 206. A second arc surface 205 is provided on one side of the second adjusting plate 208. A second positioning sleeve 209 is fixedly connected to the other side of the second adjusting plate 208. When a section of the heat exchange tube is damaged, the second positioning bolt 304 can be removed to completely separate the first adjusting plate 201 and the second adjusting plate 208. Then, the telescopic tube assembly 3 or the heat exchange tube assembly 1 can be replaced. The adjusting assembly 2 can be installed in its original position to achieve single-section replacement, which is convenient for maintenance personnel to perform maintenance work on the heat exchange tube.

[0028] The working principle of this utility model is as follows: When it is necessary to adjust the spacing between the heat exchange tube assemblies 1, the first positioning bolt 203 is first removed, and then the distance between the second flanges 303 is adjusted by adjusting the extension and retraction of the telescopic tube body 302. This allows the convex sliding strip 206 and the second adjusting plate 208 to slide inside the convex sliding groove 207, thereby causing the first adjusting plate 201 and the second adjusting plate 208 to be misaligned. Then, the distance between the first positioning sleeve 202 and the second positioning sleeve 209 is adjusted, and then the distance between the two heat exchange tube bodies 101 is adjusted. This allows the air conditioners to adapt to different signals by adjusting the number and spacing of the heat exchange tube assemblies 1 when installed on different models of air conditioners.

[0029] When a section of the heat exchange tube is damaged, the second positioning bolt 304 can be removed to completely separate the first adjusting plate 201 and the second adjusting plate 208. Then, the telescopic tube assembly 3 or the heat exchange tube assembly 1 can be replaced.
