Abstract
The present invention relates to a method for manufacturing cooler for air compressor. The cooling coil and radiator are respectively tinned and lead-coated, then assembled together and made into the invented cooler. Said cooler is cold-dipped by scaling powder to chemically degrease, then is soldered under the condition of protective gas. After said invention is adopted, the tin consumption of each cooler can be reduced by 30%, production cost can be reduced by 20%, and the acid-washing process is removed, so that it can prevent environmental pollution. Besides, it is simple in production process and easy to implement.
Description
The present invention relates to the manufacture method technical field of air compressor chillers.
At present, existing air compressor chillers is to adopt following manufacture method: at first cooling tube and radiating fin are always dressed up cooler, then cooler is carried out whole pickling, to remove degreasing and corrosion, at last cooler is carried out overall thermal immersion plating slicker solder, here the purpose of lead plating tin, the firstth, for surface anticorrosion, the secondth, cooling tube and radiating fin is welded together firmly, above-mentioned technique manufacturing method mainly contains two big shortcomings: (1) owing to there is an acid cleaning process, thereby have the pollution problem to environment; (2) owing to the hot dipping slicker solder, tin consumption is big, thereby cost of production is higher.
The purpose of this invention is to provide that a kind of tin consumption reduces, cost of production is low, remove acid cleaning process, non-environmental-pollution, manufacture method air simple, that be easy to realize contract machine cooler manufacture method.
It comprises the following steps: the manufacture method of air compressor chillers of the present invention
(1) selected cooling tube and radiating fin, cooling tube can adopt double coiled welded tube, seamless steel pipe or copper pipe;
(2) with cooling tube and the zinc-plated lead of radiating fin difference, tin lead proportion 〉=6: 4, thickness of coating 〉=5um, lead plating process of tin adopt slicker solder method or the hot dipping slicker solder method of electroplating;
(3) cooling tube behind the lead plating tin and radiating fin are always dressed up cooler, adopt existing technological method;
(4) with cooler cold soaking soldering flux, to carry out electrochemical deoiling, soldering flux is with 3-5 part zinc chloride and 1-2 part ammonium chloride, and is more as surface and oil contaminant with its 3-6 water dilution doubly, can add small amount of hydrochloric acid in soldering flux;
(5) produce hydrogen nitrogen shielding gas 〉=30m with the directly-heating ammonia destruction furnace
3/ hour, adopting the shielding gas soldering processes, hydrogen nitrogen hybrid protection gas ratio is 10-40: 90-60, brazing temperature 230-300 ℃, brazing time 〉=10 minute, but the every stove soldering of soldering oven 〉=40 coolers.
Compared with the prior art the present invention has following advantage:
(1) every cooler tin consumption reduces 30%, and cost of production reduces by 20%,
(2) owing to removed acid cleaning process, eliminated pollution to environment;
(3) adopt the shielding gas method for welding, manufacture simply, be easy to realize.
