Abstract
The utility model relates to a plate-type evaporator for a refrigerator and a water dispenser, in particular to a high-flatness single-sided roll-bond evaporator. The high-flatness single-sided roll-bond evaporator structurally comprises an aluminum plate, wherein a circulating pipeline is arranged in the aluminum plate, the circulating pipeline is connected with the lower end of an aluminum pipe arranged outside the aluminum plate, the upper end of the aluminum pipe is connected with a copper pipe, and a capillary pipe is arranged in the copper pipe. Compared with the prior art, the high-flatness single-sided roll-bond evaporator has the characteristics of reasonable design, simple structure, cost saving and improved production efficiency.
Description
Technical field
The utility model relates to a kind of plate-type evaporator for refrigerator, water dispenser, and a kind of high-flatness, single-side blown evaporimeter specifically is provided.
Background technology
Evaporimeter is one of four large equipments in the refrigerator refrigerating circulation (compressor, capillary, evaporimeter, condenser).Its effect is: cold-producing medium (such as freon etc.) enters the evaporimeter absorbing heat and vaporizes after the capillary-compensated step-down, and the saturated refrigerant gas after the vaporization is sucked pressurized, heated by compressor after going out evaporimeter, enters at last condenser and dispels the heat to the external world.
Evaporator of refrigerator has inflation type, band-tube type, threaded pipe type etc.High-flatness, single-side blown formula evaporimeter is with respect to common inflation type evaporator, and the smooth another side pipeline of one side is protruding, and disengagement area is larger when pressing close to the Refrigerating container inwall, is conducive to heat absorption, and refrigeration is better.
In the prior art, plate-type evaporator all adopts two pure commercial aluminum sheets involutory, carries out inflation after chemical treatment and hot rolling, cold finish rolling and annealing, makes evaporator pipeline single face external drum.Product quality requirement by evaporimeter sees, as the inwall of evaporimeter be more flat better (national standard for≤0.8mm).But because two aluminium sheet character of evaporimeter are identical, behind the certain pressure inflation, require smooth one side to still have to a certain degree external drum.And evaporimeter inwall external drum frost easy to hang, and outward appearance owes beautiful.An other class is aluminium coil pipe and bronze pan tube formula evaporimeter, and this class evaporimeter adopts the pipe dish in evaporating surface, and its contact form is the contact of line face, and heat-conducting area is less, and refrigeration is relatively poor, though D type aluminum pipe is arranged, coiling is difficulty relatively.
Summary of the invention
The utility model is for above problem, proposes a kind of high-flatness, single-side blown formula evaporimeter simple, that heat exchange efficiency is high of installing, thereby reduces manufacturing cost.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of high-flatness, single-side blown evaporimeter comprises aluminium sheet, is provided with circulation line in the aluminium sheet, and the described circulation line aluminum pipe lower end outer with being arranged at aluminium sheet links to each other, and described aluminum pipe upper end is connected with copper pipe, is provided with capillary in the described copper pipe.
The aluminium sheet head and the tail link to each other by rivet, and are cylindrical.
High-flatness, single-side blown evaporimeter of the present utility model carries out Mechanical Method surface extra coarse with the pure aluminum plate of selected size and aluminium alloy plate and processes, and aluminium sheet is put into the aluminium sheet unhairing machine polish, and increases surface roughness.The evaporator pipeline pattern is printed on the pure aluminum plate, and will be with the pattern aluminium sheet in drying oven, to dry.Align compound with aluminium alloy plate and riveted joint with above-mentioned aluminium sheet.Aluminium sheet after compound is heated to 480 ± 10 degrees centigrade and be incubated 60 minutes through circular heating furnace.Roll two passages at hot-rolling mill, make the deflection of two clad aluminiums reach 50～52%.According to the requirement of different size evaporimeter, roll three to four-pass at cold finishing mill.Aluminium sheet after the cold finish rolling is annealed in annealing furnace, and its temperature is 300～350 degrees centigrade, temperature retention time 3.5～4 hours.Blowing-up technology adopts air cushion process.Being about to above-mentioned aluminium sheet after compound places on the closed rubber pattern tire in the large-tonnage hydraulic press.When hydraulic press press down put in place after, open 2.5～3.5Mpa pressure nitrogen gas is held aluminium sheet, pressurising 7～8Mpa pressure nitrogen gas carries out inflation in the printing pipeline of aluminium sheet simultaneously, whole inflation process is once finished.Aluminium sheet behind the inflation can obtain pipeline single face external drum and the smooth evaporimeter aluminium sheet of evaporimeter inside wall height after shearing, punching out.After being built in capillary in the aluminum pipe, at the exit sealed with brazing, then capillary is inserted in the aluminium sheet pipeline with the punch press sealing of riveting tightly, aluminum pipe and aluminium sheet junction argon arc welding welded seal, thus form single loop.
Compared with prior art, a kind of high-flatness, single-side blown evaporimeter of the present utility model, be fused into through HTHP by an alloy aluminium sheet and ordinary aluminum plate and be in the same place, forms pipe passage by the graphite solder resist between aluminium sheet, again refrigerant loop passage of external aluminum pipe capillary formation.Because adopt the material amalgamations such as aluminium sheet, aluminum pipe, copper pipe, with respect to having saved material cost with copper pipe merely, copper pipe is that line contacts with cold tank, and aluminium sheet is that face contacts with cold tank, disengagement area has increased, and refrigerating efficiency is improved, and adopts rivet to be connected and installed more convenient.So have reasonable in design, simple in structure, saving cost, the characteristics of enhancing productivity.
Description of drawings
Fig. 1 is that a kind of structure of high-flatness, single-side blown evaporimeter is launched schematic diagram;
Fig. 2 is a kind of textural association schematic diagram of high-flatness, single-side blown evaporimeter.
The specific embodiment
Below in conjunction with the drawings and specific embodiments high-flatness, single-side blown evaporimeter of the present utility model is further described.
Shown in accompanying drawing 1,2, a kind of high-flatness, single-side blown evaporimeter comprises aluminium sheet 1, be provided with circulation line 2 in the aluminium sheet 1, described circulation line 2 aluminum pipe 3 lower ends outer with being arranged at aluminium sheet 1 link to each other, and described aluminum pipe 3 upper ends are connected with copper pipe 4, are provided with capillary 5 in the described copper pipe 4.
In the present embodiment, aluminium sheet 1 head and the tail link to each other by rivet 6, and are cylindrical.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
