The invention provides following technical scheme:
With the production method that multiple aluminium sheet is produced the inflation type evaporimeter, it comprise through cut, annealing, hacking, printing graphite, covering aluminum plate, hot rolling prolongs and presses the multiple aluminium sheet that forms, also comprise the steps:
A, multiple aluminium sheet is annealed, temperature is 410 ℃-450 ℃, and the time is 3.5h-4.5h;
B, to annealing after multiple aluminium sheet align through level(l)ing machine, bore the fabrication hole of air blowing usefulness then, fabrication hole is on the graphite circuit;
C, through fabrication hole to carrying out inflation, inflation gas is nitrogen, air pressure is 8-10MPa, aluminium sheet on the graphite circuit is heaved on multiple aluminium sheet formed pipeline, then the multiple aluminium sheet that forms pipeline is cut out;
D, die-cut to the multiple aluminium sheet after cutting out, place, the inflation aperture on pipeline welding connecting tube forms the evaporimeter blank then;
E, the evaporimeter blank is once hunted leak, the inspection air-tightness after the processing of carrying out then removing greasy dirt impurity in the surface, and is cleaned through clear water;
F, the evaporimeter blank is carried out surface passivation handle to form diaphragm, carry out the secondary leak detection then;
G, the evaporimeter blank is dried processing, bake out temperature is 150 ℃-170 ℃, and the time is 18min-20min; Automatic application is carried out in oven dry, dusts on evaporimeter blank surface, and baking and curing once more after dusting, temperature is 145 ℃-235 ℃, the time is 23min-25min;
H, inject the nitrogen of 0.2MPa, form the inflation type evaporimeter at the evaporimeter blank.
Described inflation type evaporimeter also need carry out appearance test and packing.
The inflation type evaporimeter thermal conversion efficiency that the present invention produces is high, long service life, and also production efficiency is high, and the production line automation degree is high, and cost is low.
The specific embodiment
With the production method that multiple aluminium sheet is produced the inflation type evaporimeter, it comprise through cut, annealing, hacking, printing graphite, covering aluminum plate, hot rolling prolongs and presses the multiple aluminium sheet that forms, it also comprises the steps:
A, multiple aluminium sheet is annealed, temperature is 410 ℃-450 ℃, generally is 430 ℃, and the time is 3.5h-4.5h, generally is 4h;
B, to annealing after multiple aluminium sheet align through level(l)ing machine, bore the fabrication hole of air blowing usefulness then, fabrication hole is on the graphite circuit;
C, through fabrication hole to carrying out inflation, inflation gas is nitrogen, air pressure is 8-10MPa, generally is 9MPa, aluminium sheet on the graphite circuit is heaved on multiple aluminium sheet formed pipeline, then the multiple aluminium sheet that forms pipeline is cut out;
D, die-cut to the multiple aluminium sheet after cutting out, towards installing hole, place, the inflation aperture on pipeline welding connecting tube forms the evaporimeter blank then;
E, the evaporimeter blank is once hunted leak; Leak detection is the evaporimeter blank to be put into water detect at the logical Compressed Gas of the mouth of pipe; The inspection air-tightness; After the processing of carrying out then removing greasy dirt impurity in the surface, the JH-51 type aluminic acid precipitation liquid that the processing of removing greasy dirt adopts Changzhou Junhe Technology Co., Ltd. of Jiangsu Province's Changzhou to produce cleans, then through the clear water cleaning;
F, the evaporimeter blank is carried out surface passivation handle to form diaphragm, Passivation Treatment is the evaporimeter blank to be put into the JH-43 type aluminium film forming agent solution that Changzhou Junhe Technology Co., Ltd. of Jiangsu Province's Changzhou produces carry out, and carries out the secondary leak detection then;
G, the evaporimeter blank is dried processing, bake out temperature is 150 ℃-170 ℃, and the time is 18min-20min; Automatic application is carried out in oven dry, dusts on evaporimeter blank surface, and dusting is that the sprinkling main component is the powder of epoxy resin, also comprises curing agent etc., and the enhancing anti-corrosive properties of dusting increase the service life; Baking and curing once more after dusting, temperature is 145 ℃-235 ℃, the time is 23min-25min;
H, inject the nitrogen of 0.2MPa, form the inflation type evaporimeter at the evaporimeter blank.
Then, the inflation type evaporimeter carries out appearance test and packing.
Wherein, cutting, annealing is that aluminium sheet with after cutting is annealed, and the temperature of annealing is 470 ℃ ℃, and the time is 8h, normal temperature cooling then; Annealing temperature also can be 480 ℃, 490 or 500 in this step, and the time also can be 7h or 7.5h, and annealing mainly is the greasy dirt of removing surface of aluminum plate;
