Problems solved by technology

At present, in the process of producing aluminum foil flat tubes with existing equipment in the aluminum foil radiator industry, there are usually factors such as difficult operation, single product, dirty surface, serious scratches, low pass rate, and complicated assembly, resulting in unstable brazing water tanks and easy leakage. , so that the production cost of the enterprise is high, the yield rate is low, and it also affects the degree of automatic production of the enterprise and the risk of direct customers
[0003] At present, radiators using dual-channel and multi-channel tubes account for more than 60% of the radiator market, such as figure 1 As shown, all manufacturers generally use high-frequency welded single-hole flat tubes 7 and cold-drawn flat tubes, as well as cold-bent lap joint B-type flat tubes. Disadvantages: several tubes are placed side by side in each row, and there are too many tubes, which appear messy and unsightly. Easy assembly, high cost, and easy to leak at the brazing

Embodiment 1

[0038] like figure 2 As shown in the figure, a multi-channel special-shaped flat tube according to an embodiment of the present invention includes a flat tube body 1, a top plate of the flat tube body 1 is provided with a plurality of inward first protrusions 2, and the flat tube body 1 Several inward second protrusions 3 are arranged on the bottom plate of the flat tube. L-shaped folded plate 4.

[0039] Further, the L-shaped folded plate 4 is connected to the top plate of the flat tube body 1 .

Embodiment 2

[0041] The present invention also provides a method for producing a multi-channel special-shaped flat tube, comprising the following steps:

[0042] S1. Pass the aluminum strip through the uncoiling device, the straightening device in turn, and send it to the roll forming unit;

[0043] S2. The aluminum strip is sequentially bent multiple times through the configured multi-pass roll bending die with symmetrical forming cross-section to form a tube material;

[0044] Wherein, in step S2, the multiple bending of the aluminum strip includes the following steps:

[0045] S2.1, aluminum tape positioning and folding several dimension points of the tube protrusions (including the first protrusion 2 and the second protrusion 3) (such as image 3 shown);

[0046] S2.2. Press the convex dimension point, and then bend the R angle of the pipe width dimension (such as Figure 4 shown);

[0047] S2.3. Press each bending point of the pipe and push up the sides of the two sides gradually,...

Embodiment 3

[0052] like Figure 13 As shown, put the multi-channel special-shaped flat tubes 5 into the main board 6 of the required water tank in turn, add the corresponding fins and press them to form the water tank core, put the formed water tank core into the brazing furnace, and make the composite aluminum foil after high temperature. The plate and strip A1-Si alloy brazing filler metal is melted to complete the brazing.

Abstract

The invention discloses a multi-channel special-shaped flat pipe and a production method of the multi-channel special-shaped flat pipe. The multi-channel special-shaped flat pipe comprises a flat pipe body. A top plate of the flat pipe body is provided with a plurality of inward first protrusions. A bottom plate of the flat pipe body is provided with a plurality of inward second protrusions. The top ends of the first protrusions abut against the top ends of the second protrusions. The middle of the flat pipe body is provided with two L-shaped folded plates abutting against each other. The multi-channel special-shaped flat pipe has the beneficial effects that all defects of existing flat pipes are overcome from technological design through the porous special-shaped channel flat pipe, the one-pipe multi-hole design can be achieved (in other words, multiple flat pipes adopted originally can be replaced with one pipe at present, and the performance is not reduced than before), the pipe shape size can be freely designed, plane butt connection is adopted for overlap points, the operation cost of production enterprises is greatly saved, and product quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of heat dissipation equipment, in particular to a multi-channel special-shaped flat tube and a production method thereof. Background technique [0002] With the rapid development of various heat transfer heat dissipation technologies and air conditioning technologies in China, aluminum foil flat tubes are more and more applied to various equipment heat dissipation, air conditioning and other fields. At present, in the process of producing aluminum foil flat tubes with existing equipment in the aluminum foil radiator industry, there are usually many factors such as difficult operation, single product, dirty surface, serious scratches, low qualification rate, complicated assembly, unstable brazing water tank and easy leakage. , so that the production cost of the enterprise is high, the yield is low, and it also affects the degree of automated production of the enterprise and the risk of direct customers.
