Description
Technical field：
The present invention relates to a kind of process technology of evaporator, is especially a kind of manufacturing process of evaporator.
Background technology：
At present, the refrigerating chamber of refrigerator, showcase, wine cabinet etc. generally uses inflation type evaporator, and inflation type evaporator is logical
Composite plate is formed after crossing the steps such as the annealing of aluminium sheet, roller brush, cladding plate, hot rolling, then inflation type evaporation is manufactured by way of inflation
Device.The complex manufacturing technology of this evaporator, low production efficiency, percent defective is high, and production cost is higher.
The content of the invention：
The technical problem to be solved by the invention is to provide a kind of manufacture for the evaporator that technique is simple, production efficiency is high
Technique, the evaporator heat transfer efficiency of manufacturing process manufacture are high.
The technical solution of the present invention is to provide a kind of manufacturing process of evaporator, and it comprises the following steps：
The first step, according to refrigerator, the requirement of showcase heat exchange amount and product installation dimension, design aluminium sheet structure, aluminum pipe caliber
And distribution of the aluminum pipe on aluminium sheet；
Second step, aluminum pipe is bent into the snakelike shape aluminum pipe formed by several bending arc tube and straight tubes；
3rd step, snakelike shape aluminum pipe is compressed to flat aluminum pipe；
4th step, brazing flux is coated on the flat aluminum pipe suppressed, flat aluminum pipe is fixed with aluminium sheet with fixture, is put into pricker
Soldering is carried out in brazier；
5th step, fixture is released after the completion of welding, inlet tube and outlet are fixed respectively in flat aluminum pipe entrance point and the port of export
Pipe；
6th step, carry out processing of dusting.
Preferably, the soldering oven is controlled atmosphere continuous brazing furnace.
Preferably, aluminum pipe is welded and fixed with inlet tube and outlet.
Further, after the completion of soldering, plane correction also is carried out to aluminium sheet or both ends are integrally bent.So it is adapted to not
With desired refrigeration plant.
The present invention has advantages below compared to prior art：The present invention is improved whole manufacturing process, is simplified
Manufacturing process, improves production efficiency, and obtained product design is smooth attractive in appearance, and heat exchange efficiency is high.
Brief description of the drawings
Accompanying drawing is the structural representation of evaporator produced by the present invention.
Embodiment：
With regard to embodiment, the invention will be further described below in conjunction with the accompanying drawings：
Embodiment
A kind of evaporator as depicted, its specific manufacturing process, comprises the following steps：

The drying time of aluminium sheet 1 wherein is 5-12 minutes, and drying temperature is 180-300 DEG C, and preheating time is 30-55 minutes, preheating
Temperature is 450-620 DEG C；Heat time is 4-13 minutes, and heating-up temperature is 620-680 DEG C；
5th step, fixture is released after the completion of welding, inlet tube and outlet are fixed respectively in flat aluminum pipe entrance point and the port of export
Pipe；
6th step, after the completion of soldering, according to needing to the progress plane correction of aluminium sheet 1 or both ends Integral bending for refrigeration plant
Folding, finally carries out processing of dusting, in favor of anti-corrosion and improves overall aesthetics.
Only preferred embodiments of the present invention are described above, but are not to be construed as limiting the scope of the invention.
