Abstract
The invention discloses a manufacturing process of an evaporator. The manufacturing process of the evaporator comprises the steps of 1, designing an aluminum plate structure, the diameter of aluminum pipes, and the distribution of the aluminum pipes on the aluminum plate according to the requirement on heat exchange capacity of a refrigerator and a display cabinet and the product mounting dimension; 2, bending the aluminum pipes into a snake-shaped aluminum pipe composed of a plurality of bent arc-shaped pipes and straight pipes; 3, pressing the snake-shaped aluminum pipe into a flat aluminum pipe; 4, coating soldering flux on the flat aluminum pipe, clamping and fixing the flat aluminum pipe and the aluminum plate through a clamp, and then soldering through a controllable atmosphere soldering furnace; 5, releasing the clamp after welding, and respectively welding and fixing an inlet pipe and an outlet pipe at the inlet end and the outlet end of the flat aluminum pipe; 6, spraying powder. According to the manufacturing process of the evaporator, the process is simplified, the production efficiency is increased, the product yield is high, the cost is low, and mass production can be carried out.
Description
Technical field:
The present invention relates to a kind of process technology of evaporimeter, is specifically a kind of manufacturing process of evaporimeter.
Background technology:
At present, the refrigerating chamber of refrigerator, showcase, wine cabinet etc. generally adopts inflation type evaporator, and inflation type evaporator forms composite plate after the step such as annealing, roller brush, cladding plate, hot rolling by aluminium sheet, then manufacture inflation type evaporator by the mode of inflation.The complex manufacturing technology of this evaporimeter, production efficiency is low, and percent defective is high, and production cost is higher.
Summary of the invention:
Technical problem to be solved by this invention is, provides the manufacturing process of the evaporimeter that a kind of technique is simple, production efficiency is high, and the evaporator heat exchange efficiency that this manufacturing process manufactures is high.
Technical solution of the present invention is, provide a kind of manufacturing process of evaporimeter, it comprises the following steps:
The first step, changes thermal requirement and product installation dimension according to refrigerator, showcase, design aluminium sheet structure, aluminum pipe caliber and the distribution of aluminum pipe on aluminium sheet;
Second step, is bent into the snakelike shape aluminum pipe formed by several bending arc tubes and straight tube by aluminum pipe;
3rd step, is compressed to flat aluminum pipe by snakelike shape aluminum pipe;
4th step, the flat aluminum pipe suppressed applies brazing flux, flat aluminum pipe and aluminium sheet is fixed with fixture, puts into soldering oven and carries out soldering;
5th step, has welded rear releasing fixture, fixes inlet tube and outlet respectively at flat aluminum pipe entrance point and the port of export;
6th step, carries out process of dusting.
As preferably, described soldering oven is controlled atmosphere continuous brazing furnace.
As preferably, aluminum pipe and inlet tube and outlet are welded and fixed.
Further, after soldering completes, also plane correction or two ends entirety bending are carried out to aluminium sheet.The different refrigeration plant required can be adapted to like this.
The present invention has the following advantages compared to prior art: the present invention improves whole manufacturing process, simplifies manufacturing process, improves production efficiency, and obtained product design is smooth attractive in appearance, and heat exchange efficiency is high.

Second step, is bent into the snakelike shape aluminum pipe formed by several bending arc tubes and straight tube by aluminum pipe 2;
3rd step, is compressed to flat aluminum pipe by snakelike shape aluminum pipe, is compressed to flat aluminum pipe with forcing press, and in the present embodiment, the diameter of snakelike shape aluminum pipe is 8mm, and when there is not defect, pressure 2mm, so that flat aluminum pipe has enough contacts area to contact with aluminium sheet 1;
4th step, the flat aluminum pipe suppressed applies brazing flux, with fixture, flat aluminum pipe and aluminium sheet are fixed, put into that soldering oven carries out drying, preheating, heating, then carry out soldering, described soldering oven is controlled atmosphere continuous brazing furnace, flat aluminum pipe and aluminium sheet 1 drying time are wherein 5-12 minute, bake out temperature is 180-300 DEG C, and preheating time is 30-55 minute, and preheat temperature is 450-620 DEG C; Heat time is 4-13 minute, and heating-up temperature is 620-680 DEG C;
5th step, has welded rear releasing fixture, fixes inlet tube and outlet respectively at flat aluminum pipe entrance point and the port of export;
6th step, after soldering completes, according to refrigeration plant need to aluminium sheet 1 carry out plane correction or two ends entirety bending, finally carry out process of dusting, be beneficial to anticorrosion and improve entirety aesthetics.
Below only just preferred embodiment of the present invention is described, but can not be interpreted as it is limitations on claims.
