Product Description

Professional Parallel Flow Micro Channel Thermal Extrusion for Automobile Heat Exchanger


Aluminum alloy harmonica tube is a necessary material for automotive air conditioners. With the rapid development of the automobile industry, the demand for aluminum alloy harmonica pipes for automobile air conditioners is increasing day by day.

The harmonica pipe is named for its cross-section that resembles a harmonica. During use, the harmonica tube is filled with cooling medium and used as a fluid conduit in the heat exchanger. Usually, the harmonica pipe is designed with 5-25 holes according to the needs, the wall thickness is 0.6-1.0mm, and the height is about 5mm. The user first coils the harmonica tube into a serpentine shape on the special mold, and then coats both sides with a heat dissipation tape with a thickness of 0.15-0.2mm of brazing filler metal, and then thermally assembles the two, and heats and welds them in an inert gas shielded brazing furnace. , made into a heat exchanger, a typical heat exchanger structure.

Technical details:

(1) The harmonica tube has a thin wall, a large number of holes, and is difficult to form during extrusion production. Figure 2 shows the 25-L harmonica pipe used for the "Audi" car air conditioner evaporator. The 25 channels should be relatively closed, and the microstructure of the weld should be free of defects, not ruptured during cold deformation, and able to withstand a burst pressure greater than 8MPa.

(2) There are many densely packed cavities in the product, and the inner cavity area is small. The metal distribution in the shunt cavity of the extrusion die should be reasonable, and the stability of the die core should be strong. Molds designed by traditional methods cannot produce qualified products, so there must be new ideas in design.

(3) To produce high-standard harmonica pipes, the precision of mold manufacturing should be high, and the error of 25 mold cores relative to the center of the mold should be small.
