Description

Technical Field

[0001] This utility model relates to the field of aluminum flat tubes, and in particular to a high heat exchange parallel flow aluminum flat tube for automotive air conditioning. Background Technology

[0002] Parallel flow heat exchange aluminum flat tubes are tubes made of aluminum with a flat shape and multiple parallel channels inside. These channels come in various shapes, including rectangular, triangular, and circular, and are typically narrow. This design allows for more efficient heat transfer and exchange.

[0003] However, the existing parallel flow heat exchange aluminum flat tubes used in automotive air conditioning have a smooth outer surface and need to be welded together with heat dissipation fins to form a whole. Since there are no fixed points between the fins and the aluminum flat tubes before welding, displacement is very easy to occur during assembly and welding. At the same time, the smooth surface has a limited contact area with the air, which affects the heat exchange capacity of the aluminum flat tubes themselves.

[0004] Therefore, it is essential to invent a high-heat-exchange parallel-flow heat-exchange aluminum flat tube for automotive air conditioning. Utility Model Content

[0008] Preferably, the slot includes a trapezoidal slot and a T-shaped slot, which are integrally formed on the outer surface of the aluminum flat tube. The trapezoidal slot and the T-shaped slot are connected to each other, with the T-shaped slot located outside the trapezoidal slot. The trapezoidal slot and the T-shaped slot are fixedly connected to one end of the corresponding hollow connecting tube by plugging and inserting.
