Material

copper pipe, the common diameter we can supply isΦ7（1/4”/6.35）

Φ7.94(5/16”), Φ9.52(3/8”). galvanized plate, aluminum fins etc.

Our main fin mold including:

1) Φ9.52, 4Rx16T Pitch: 25mm, line spacing 21.65mm, cross arranged

2) Φ9.52, hole spacing: 25mm, line spacing 21.65mm, copper fins

3) Φ7, hole pitch: 21, line spacing 12.7mm, hydrophilic aluminum foil, cross arrangement, isosceles triangle

4) Φ12 (1/2"), pitch: 35mm, line spacing 35mm, square arrangement

5) Φ7.94 (5/16"), pitch: 25mm, line spacing 21.65mm, cross arrangement, equilateral triangle

6) Φ9.52 (3/8"), pitch: 25mm, line spacing 21.65mm, cross arrangement, equilateral triangle

7) Φ15.88 (5/8”), pitch: 50mm, line spacing 50mm, square arrangement

8) Φ12.7 (1/2"), pitch: 31.75mm, line spacing 27.5mm, cross arranged.

Process

How to make a copper condenser

Straightening & Cutting copper tube:

Sometimes we use fully automatic machine, and sometimes we do it by manual.

Aluminum foil:

According to aperture, hole distance, number of holes, line spacing, chip spacing, number of rows, and number of fins,

Manually adjust the mold, cut the knife, and punch the rolled aluminum foil into the fins on the machine.

Copper tube insert with above aluminum fin:

Remove the stamped and cut aluminum fins, install the side baffle, and insert the bent copper tube into the aluminum fin hole through the baffle hole.

Tube expansion:

Put it on the tube expander, with the side of the baffle facing down, the other side of the baffle on the upper side, start the machine, and expand the tube. (The diameter of the copper tube becomes larger and tightly bonded to the aluminum fins)

Degreasing:

Put them into an oven.

Welding copper elbows:

Automatic welding and manual welding.

In the first case: if piping is not required, leave one inlet and one outlet at each end.

The second case: if piping is required, leave the corresponding pipe hole without installing the elbow.

Impurity:

Take one end of the inflatable gun and vent it at one end.

Welding corners (or welded pipes, no corners or piping, directly bet plugs)

Nitrogen test. The fins are bent, manually trimmed.

Drying:

water removal,put in the oven.

Then packed by carton and pallets.
