Problems solved by technology

Before the flat tube coming out of the cooling water tank reaches the coiler, the water on the surface of the flat tube must be removed, otherwise the flat tube will be scrapped due to oxidation, but the distance between the cooling water tank and the coiler is limited, and the flat tube The discharge speed of the flat tube is fast, so it often happens that the flat tube is scrapped due to the inability to remove the water on the surface of the flat tube
[0003] At present, in the production process of flat tubes, water cooling has been used to cool the flat tubes. In order to ensure that the surface moisture of the flat tubes is removed, it is necessary to use a large amount of hot air to dry the flat tubes after the water cooling process, resulting in flat tubes production costs are high

Embodiment Construction

[0023] see figure 1 The invention discloses a cooling method for micro-channel aluminum flat tubes, comprising a water cooling step, a compressed air purging step, and an oven hot air baking step which are carried out in sequence.

[0024] Specifically in this embodiment, after the aluminum rod is extruded by the extruder 100, it is deformed into a flat tube 600, and then the flat tube first passes through the cooling water tank 220 of the cooling device 200, and after the flat tube exits the cooling water tank 220, it forms a 20 ° climbing, and through the compressed air purging device 300, and then after passing through the oven 400, it is wound on the coiler 500 to form a coil.

[0025] A PLC control board 110 is provided on the extrusion machine 100, and the PLC control board 110 is used as the central processing unit in the control system in this embodiment.

[0026] see image 3 , in this embodiment, the cooling device 200 includes the above-mentioned cooling water tan...

Abstract

The invention discloses a cooling method for a microchannel aluminum flat tube, which comprises a water cooling step, a compressed air purging step, and an oven hot air baking step which are carried out in sequence. By using the cooling method, on the basis of cooling the flat tube to room temperature, less time and space are occupied, less energy is consumed, water on the surface of the flat tube can be completely removed, and automatic operation can be realized.

Description

technical field [0001] The invention relates to a cooling method for a microchannel aluminum flat tube. Background technique [0002] The extrusion of the microchannel flat tube is relatively large, and the temperature of the aluminum rod is very high after being transformed into a flat tube through the mold, so the flat tube must be cooled. Compared with water cooling, air cooling consumes more energy and has insufficient cooling strength, so water cooling is usually used in the industry. Before the flat tube coming out of the cooling water tank reaches the coiler, the water on the surface of the flat tube must be removed, otherwise the flat tube will be scrapped due to oxidation, but the distance between the cooling water tank and the coiler is limited, and the flat tube The discharge speed of the flat tube is fast, so it often happens that the flat tube is scrapped due to the inability to remove the water on the surface of the flat tube. [0003] At present, in the prod...
