Description
Technical field
A kind of flat-plate evaporators are the utility model is related to, especially suitable for directly being contacted with the air in refrigerator compartment.
Background technology
In the prior art, the pipeline of roll-bond evaporator is divided into two kinds of two-sided external drum and single side external drum.Two-sided external drum it is board-like
Positive and negative two surfaces of evaporator are uneven, and since roll-bond evaporator is directly with food heat exchange, surface is not when in use
It is smooth not only unsightly, but also there are evaporator surface boss it is easy to wear the defects of；And single side drum type evaporator is then gram
The drawbacks described above of two-sided external drum is taken, but the blowing-up technology of single side drum type evaporator to the surface pretreatment process of aluminium sheet and is blown
The technical requirements such as expanding installation mould and process are higher, and more important is flatness not to reach technical requirements, and pipeline formation degree is poor, together
When due to the heat dissipation area of single side external drum evaporator it is also smaller, refrigerating efficiency is low.Current roll-bond evaporator processes the main of skill
Flow is to print pipeline shape with spheroidal graphite powder on two blocks of aluminium sheets, then is pressed with mould, and hot rolling, annealing, then blow height in port
Calm the anger cubical expansion shape, the pipeline that its aluminium sheet scribbles spheroidal graphite powder in printing will be blown afloat, and form pipeline, last clipped to wait system
Into.The even roll-bond evaporator of single side drum, since the property of two blocks of aluminium sheets of aluminium sheet is close, requires after certain pressure inflation
Smooth one side still has a degree of external drum, it is even more impossible to realize that the position in inflation, putting thing is smooth, rather than puts object plane steaming
Device pipeline protrusion is sent out in favor of heat exchange.
The content of the invention
The task of the utility model is to provide one kind, and can to put thing position in evaporator smooth, and puts thing position protrusion non-
Local single side protrusion flat-plate evaporators.
The task of the utility model, which is done in such a way that, is characterized in that：Flat-plate evaporators are by upper strata aluminium sheet and lower floor's aluminium
Plate is formed, and punch process has a pipeline on the upper and lower layer aluminium sheet face, and at least one layer of aluminium sheet is in upper strata aluminium sheet and lower floor's aluminium sheet
Composite plate, this one side with pipeline is upper in the composite plate is uniformly coated with solder layer, scribbles the composite plate of solder layer with there is pipe
Pipeline on this floor aluminium sheet on road is harmonious, and is assembled together to face placement and forms evaporator pipeline, evaporator pipeline in composition
With after clamp weldering sintering furnace in weld.It is smooth that the pipeline processed puts thing position, and non-to put thing position pipeline raised.
The utility model has the following effects that：Since this method is using stamping, it is possible to make of different shapes
Upper and lower stamping die, from face according to the raised different requirements of evaporator surface pipeline, makes different flat-plate evaporators.For example needing
Want smooth and put thing part, very smooth plane can be struck out, needing the higher raised opposite face for putting thing position,
Higher raised pipeline can be gone out, and can accomplish precisely, so as to fulfill smooth at the position for putting thing, rather than to put thing
Face evaporator pipeline protrusion is in favor of heat exchange.Further, can be according to different refrigerators with the method for the utility model
The difference that refrigeration requires, makes the height of projection difference of different position pipelines, so that the flow of refrigerant is different, reaches different
The temperature at position also different effect.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；Fig. 2 is the profile of the utility model.
Drawing explanation：1st, upper strata aluminium sheet, 2, lower floor's aluminium sheet, 3, raised, 4, pipeline, 5, solder layer.
Embodiment
The technical program, which is to provide one kind, to put that thing position is smooth in evaporation, and is putting raised local single in thing position
The flat-plate evaporators of the local single side protrusion of face protrusion, specific embodiment are as follows:Flat-plate evaporators are by upper strata aluminium sheet 1 and lower floor's aluminium
Plate 2 is formed, and punch process has pipeline 4 on the upper and lower layer aluminium sheet face, and it is smooth that the pipeline processed puts thing position, non-to put thing portion
Position pipeline protrusion 3, at least one layer of aluminium sheet is composite plate in upper strata aluminium sheet and lower floor's aluminium sheet, this in the composite plate with pipeline
Simultaneously upper to be uniformly coated with solder layer 5, the composite plate for scribbling solder layer is harmonious with the pipeline on this layer of aluminium sheet for having pipeline, right
Face, which is placed to be assembled together, forms evaporator pipeline, and evaporator pipeline after clamp in weldering sintering furnace with welding in composition.
Outlet tube and inlet tube are assembled after welding, liquid outlet and inlet are installed on the outlet tube and inlet tube.
The making step for making flat-plate evaporators is as follows：1st, first according to the shape of the shape pipeline protrusion of flat-plate evaporators
And size, the punching press punch-pin and cavity plate of the respective shapes used in the aluminium sheet of making pipeline upper surface, wherein, used in a face aluminium sheet
Punch-pin and cavity plate are plane at the pipeline of part；And the punch-pin of another side aluminium sheet is raised in the pipeline of the corresponding site with cavity plate；
2nd, the punch-pin in the first face and cavity plate are installed on stamping equipment；3rd, aluminium sheet is prepared, it is stamping on punching machine, with same side
Method, produces the aluminium sheet of pipeline first surface, is ordinary aluminum plate by the aluminium sheet used in above-mentioned upper surface, and aluminium sheet used in lower surface is
Clad aluminium, clad aluminium scribbles the one side direction that direction is harmonious with upper surface aluminium sheet in punching press of solder, by made aluminium
Two blocks of aluminium sheets are combined according to the direction for being mutually made into pipeline；4th, stepped up with fixture, be placed on sintering welding, weldering in soldering sintering furnace
Fitted into after connecing, outlet tube.
Flat-plate evaporators are made with the method identical with embodiment one, after shaping, are converted into U-shaped, being a difference in that to evaporate
The pipeline upper surface aluminium sheet for putting thing position of device makes plane, and lower surface aluminium sheet makes convex surface；And above and below the pipeline at other positions
Surface aluminium sheet makes convex surface.It is smooth that flat-plate evaporators made by the utility model can put thing position in evaporator, and
The evaporator of the non-local single side protrusion for putting thing position protrusion, thereby may be ensured that to put thing position smooth, beautiful, and put thing non-
Position is raised for two sides, thus ensure to put thing position it is smooth while, in turn ensure that higher refrigerating efficiency.
Flat-plate evaporators are made with the method identical with embodiment one, while after evaporator is molded, are converted into U-shaped.Steaming
Hair device U turns up the pipeline at position, its height of projection is more than the height of projection for putting thing position bottom surface section.
