Abstract
The invention discloses an air cooling refrigerator and freezer serpentine parallel flow condenser manufacture process. A condenser comprises flat tubes bent in serpentine shapes and fins arranged between the flat tube, the inlets of the flat tubes are connected to an inlet pipe component, and the outlets of the flat tubes are connected to an outlet pipe component. The process includes utilizing a bending device to bend the flat tubes into serpentine shapes; utilizing a fin forming machine to machine the fins; utilizing a special tooling to position the bent flat tubes and install the fins, and installing upper and lower edge plates on the fin of the outer side for protecting the fins; fixing the product after assembly, and welding the product in a controllable atmosphere brazing furnace; after discharging the product, fixing the inlet pipe component and the outlet pipe component to two ends of the flat tubes respectively; performing helium test, installing a fixing support after passing the helium test. The manufacture process has the advantages that the traditional process is broken through, efficiency is improved, and the manufactured product is high in heat exchanging efficiency, small in size and light.
Description
Technical field:
The present invention relates to a kind of process technology of condenser, is specifically the manufacturing process of a kind of wind cooling refrigerator, refrigerator coiled parallel flow condenser.
Background technology:
Condenser is the vitals carrying out heat conversion in refrigerator or refrigerator, and its structure directly affects refrigeration.Existing wind cooling refrigerator condenser adopts and revolves wing formula condenser, and ribbon spiral is wrapped in the combining structure on steel pipe, and volume is comparatively large, heavier-weight, and steel pipe processing technology is complicated, and surface needs electrophoresis to improve product antiseptic power.The condenser of refrigerator-freezer adopts copper pipe fin type condenser, assemble with aluminium foil with after copper pipe expand tube, namely after coolant channel pipe (copper pipe) puts the fin of some, by method that is mechanical or hydraulic pressure, the diameter of pipe is increased by the head that rises, make pipe and fin close contact, because copper pipe is the main material of condenser, and China's copper resource has geneogenous deficiency, along with the development of refrigeration industry, copper consumption is increasing, and copper resource is more and more in short supply, cause copper valency constantly to rise, bring cost pressure to manufacturer.
Summary of the invention:
Technical problem to be solved by this invention is, the manufacturing process of a kind of technique is simple, production efficiency is high wind cooling refrigerator, refrigerator coiled parallel flow condenser is provided, the coiled parallel flow condenser unit volume heat exchange property that this manufacturing process makes is high, and volume is little, and quality is light.
Technical solution of the present invention is, the manufacturing process of a kind of wind cooling refrigerator, refrigerator coiled parallel flow condenser is provided, condenser comprises the flat tube being bent into snakelike shape and the fin be arranged between flat tube, the entrance point of flat tube connects inlet tube assembly, the port of export connection outlet pipe assembly of flat tube, it comprises the following steps:
The first step, selects aluminum or aluminum alloy flat tube, is bent into snakelike shape flat tube with angle pipe equipment;
Second step, requires design fin parameter according to product heat exchange property, and processes fin with fin forming machine;
3rd step, by frock by the flat tube location after bending, carry out fin installation, at condenser outermost fin, place installs lower side plate for the protection of fin;
4th step, after having assembled, fixes product, then puts into controlled atmosphere soldering oven and welds;
5th step, fixes inlet tube assembly and outlet assembly respectively at flat tube two ends of coming out of the stove;
6th step, carries out helium inspection, the qualified rear mounting and fixing bracket of helium inspection.
As preferably, described angle pipe equipment is bending machine.
Further, the fixed form of flat tube and fin is fixing for gripping or tying up.
The present invention has the following advantages compared to prior art: the structure that the present invention is directed to coiled parallel flow condenser is innovated whole manufacturing process, breach the manufacture craft of refrigerator, refrigerator condenser, improve production efficiency, and obtained condenser long service life, heat exchange efficiency is high, aluminium or aluminium alloy pipe substitute copper pipe, and volume is little, and quality is light.
Accompanying drawing explanation
Accompanying drawing is the structural representation of the condenser that the present invention makes.
Detailed description of the invention:
Below in conjunction with detailed description of the invention, the invention will be further described:

The first step, selects aluminum or aluminum alloy flat tube, and be bent into the flat tube 1 of snakelike shape with bending machine, bending machine can select manual tube bender, also can select semi-automatic or automatic pipebender;
Second step, requires design fin parameter according to product heat exchange property, and processes fin 2 with fin forming machine;
3rd step, locates the flat tube 1 after bending with special tooling, carries out fin 2 and install, and installs side plate 5 and lower side plate 6 for the protection of fin at condenser outermost fin 2 place;
4th step, after having assembled, is undertaken product gripping or tie up fixing, puts into controlled atmosphere soldering oven and weld after fixing;
5th step, has welded rear releasing fixture or strapping, fixes inlet tube assembly 3 and outlet assembly 4 respectively at flat tube 1 two ends of product of coming out of the stove;
6th step, carries out helium inspection, the qualified rear mounting and fixing bracket of helium inspection.
Below only just preferred embodiment of the present invention is described, but can not be interpreted as it is limitations on claims.
