[0002] Microchannel aluminum flat tube is a thin-walled porous flat tubular material made of refined aluminum rods, through hot extrusion, surface zinc spraying anti-corrosion treatment, mainly used in air-conditioning systems of various refrigerants. Currently, the most common microchannel aluminum flat tube is mainly a sheet-like aluminum tube structure with an assembly part set on the outside. A microchannel is opened in the aluminum tube structure to guide the refrigerant. When in use, two adjacent sheet-like aluminum flat tubes are connected by the assembly part to form a row of aluminum flat tube structures, thereby improving the heat dissipation efficiency. For example, an assembled aluminum flat tube structure with application number CN202222615167.1 includes an aluminum flat tube outer frame, and the aluminum flat tube outer frame includes two aluminum sheet substrate layers. A woven metal mesh is installed on one side of each aluminum sheet substrate layer. The woven metal mesh is fixed with a number of reinforcing rectangular bars, and the distance between adjacent reinforcing rectangular bars is the same; the above common types of aluminum flat tubes still have the following shortcomings in actual applications:

[0003] The sheet-like hollow aluminum flat tube is relatively light and thin. During assembly, the middle part is subjected to force, which may cause the aluminum flat tube to bend or dent easily. Once the aluminum flat tube is bent or damaged, the air circulation therein will be blocked, thus affecting the heat dissipation effect. Utility Model Content

[0004] The utility model aims to provide an assembled aluminum flat tube structure to solve the problem that the existing aluminum flat tubes mentioned in the above background technology are easily deformed by force during assembly.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled aluminum flat tube structure, comprising a tube rack and an assembly plug plate snap-fitted onto the tube rack, hollow aluminum flat end tubes are fixedly arranged at both ends of the assembly plug plate, a plurality of assembly slots are provided on the surfaces of the two hollow aluminum flat end tubes, a microchannel aluminum flat tube assembly is provided between the two assembly slots arranged opposite to each other, the microchannel aluminum flat tube assembly comprises a heat exchange aluminum flat tube and a flat plug fixedly arranged at both ends of the heat exchange aluminum flat tube, a refrigerant microchannel extending into the interior of the heat exchange aluminum flat tube is provided inside the flat plug, and a plurality of evenly distributed heat dissipation aluminum fins are fixedly provided on one side of the heat exchange aluminum flat tube.

[0006] Preferably, the flat insert is matched with the assembly slot, and a sealing gasket is fixedly provided on the top end of the flat insert; the assembly is simple and the sealing effect is significant.

[0007] Preferably, an assembly lock disk is fixedly provided on the outer side of the two flat inserts, and a locking nail hole is provided on the assembly lock disk; after assembly, it is stable and reliable and not easy to loosen or fall off.

[0008] Preferably, one end of the hollow aluminum flat end tube away from the assembly plug plate is fixedly connected to a refrigerant flow pipe opening, which is convenient for external pipe connection to achieve the circulation of the refrigerant.

[0009] Preferably, a plurality of pin holes are provided on the surface of the assembly plug board, so as to improve the stability after assembly.

[0010] Preferably, the cross-section of the refrigerant microchannel is set to be triangular; the structural strength of the microchannel aluminum flat tube assembly can be increased, and the anti-extrusion ability is more significant.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The aluminum flat tube fixes multiple microchannel aluminum flat tube assemblies between two hollow aluminum flat end tubes by means of buckles, thereby forming a flat aluminum flat tube structure. The structural strength of the aluminum flat tube can be improved without affecting the ventilation and heat exchange of adjacent microchannel aluminum flat tube assemblies. The aluminum flat tube is assembled into rows by buckles. During assembly, the microchannel aluminum flat tube assemblies on the inner side are not easily bent by force. The surface is provided with heat dissipation aluminum sheets, which can improve the heat exchange effect. The aluminum flat tube has the characteristics of high structural strength, simple assembly, low difficulty and significant heat exchange effect. BRIEF DESCRIPTION OF THE DRAWINGS
