[0003] Although there are technical reports on bionic wavy fins used in air-conditioning heat exchangers, the main body of this kind of fins has a wavy shape of continuous protrusions and pits. However, from the analysis of its fin structure diagram, it can be seen that the structure has different heights on different sections, and the curvature difference between protrusions and pits is relatively large. Therefore, from the perspective of processing technology, the manufacturing cost of this type of fin At the same time, this way of processing the fins as a whole with protrusions and pits also weakens the overall strength of the fins, which is not conducive to its assembly with the copper tube

Embodiment Construction
[0033] see in conjunction Figure 1 to Figure 10 As shown, according to an embodiment of the present application, a tube-fin heat exchange assembly includes:
[0034] Fins, the fins include a flat sheet 1, and a plurality of protrusions and / or pits are arranged on the flat sheet 1;
[0035] In the direction from the windward side of the flat sheet 1 to the windward side, a plurality of the protrusions and / or the recesses are non-uniformly distributed.
[0036] In the structure with the flat sheet 1 as the fin, there are protrusions and / or pits on the flat sheet 1, and it is not easy to deform the flat sheet 1, so it will not affect the subsequent assembly, which is equivalent to improving the assembly efficiency In addition, especially along the direction from the windward side of the flat sheet 1 to the windward side, the protrusions and / or pits are non-uniformly distributed, increasing the heat transfer area, and making the airflow flowing through the surface of the flat sh...

The application provides a tube-fin heat exchange assembly, a heat exchanger and an air conditioner. The tube-fin heat exchange assembly includes fins, and the fins include flat sheets, and the flat sheets are provided with a plurality of protrusions and / or pits; in the direction from the windward side of the flat sheet to the wind outlet , a plurality of said protrusions and / or said pits are non-uniformly distributed. The fins are provided with non-uniformly distributed protrusions and / or pits. Since the fins are of a flat structure, the deformation of the entire fin surface due to the processing of protrusions or pits with different heights is avoided. It affects the subsequent assembly; at the same time, the heat transfer area of the fins is increased, which can generate horizontal and vertical airflow disturbances and improve heat transfer efficiency.
Description
technical field [0001] The application belongs to the technical field of air conditioners, and in particular relates to a tube-fin heat exchange assembly, a heat exchanger and an air conditioner. Background technique [0002] Tube-fin heat exchangers are widely used in air conditioners, HVAC equipment and other fields, and the thermal resistance of this type of heat exchanger concentrated on the air side outside the tube can reach about 80-90% of the total thermal resistance, so the fin structure Optimization can effectively improve the heat transfer performance of such heat exchangers. [0003] Although there are technical reports on bionic wavy fins used in air-conditioning heat exchangers, the main body of this kind of fins has a wavy shape of continuous protrusions and pits. However, from the analysis of its fin structure diagram, it can be seen that the structure has different heights on different sections, and the curvature difference between protrusions and pits is r...
