Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a heat dissipation component and a condenser for an automobile air conditioner. Background Art

[0002] With the gradual application of natural refrigerants such as R744, R600, and R290 in automobile air conditioners, and the gradual improvement of flat tube processing technology, the heat transfer performance per unit area of ​​the flat tube itself has gradually improved. Therefore, in order to balance the thermal resistance when designing the heat exchanger, the heat transfer performance of the air side (wing side) is required to be improved accordingly.

[0003] In order to increase the heat transfer performance of the wing strip side, possible methods are to increase the heat transfer area of ​​the wing strip side and increase the air disturbance on the wing strip side. The commonly used method is to increase the density of the wing strip and increase the window angle, but these two methods will cause various difficulties in wing strip processing and a significant increase in wind resistance, which is not conducive to improving the performance of the actual vehicle.

[0004] In actual production, the current process habit is that the width of the wing band and the flat tube is equivalent, and the mainstream is that the width is the same or the wing band is 1~2mm wider than the flat tube. In the prior art, since there is no limit structure design on the wing band, it often happens that the flat tube and the wing band become loose and distorted again after being aligned. Therefore, the utility model improves the existing wing band, increases the heat dissipation area and improves the stability of the flat tube.

[0005] The specification of the Chinese utility model patent application CN219531784U discloses a heat dissipation assembly and a condenser for automobile air conditioners, including a flat tube and a corrugated wing for the flow of a refrigerant medium, wherein the crests and troughs of the wing are in contact with the main heat dissipation surface of the flat tube, and is characterized in that an extension section is integrally provided on both sides of the wing, and a limiting protrusion is provided on the extension section, the limiting protrusion is higher than the crests and troughs of the wing, and a receiving groove is formed between the two limiting protrusions on the crests and troughs, and the flat tube is placed in the receiving groove. The utility model eliminates the risk of loosening and falling off of the wing and the flat tube during production and transportation, which is conducive to simplifying the production process and improving production efficiency, but the device does not solve the problem of easy installation and circulation condensation. For this reason, we propose a heat dissipation assembly and a condenser for automobile air conditioners. Summary of the invention
