Description
Technical field
This utility model belongs to air-conditioning and Refrigeration Engineering technical field, specifically, is related to a kind of air-conditioning heat exchanger assembly.
Background technology
In air-conditioner, evaporator-condenser two heat exchangers are one of six big part of air-conditioning, and spare part at most, processing work
Skill is most, weld most complicated part, the direct shadow of height of its generalization standardization, manufacture efficiency and erection welding quality
Ring the quality and benefits of air-conditioning products.
Heat exchanger assembly generally includes U-tube, fin and end plate, after the fin and end plate of the reserved circular hole of U-tube insertion,
Three is combined closely by an expansion tube process or increase secondary enlarging technique, heat exchanger assembly is constituted with this, is exchanged heat
Device assembly carries out the combination assembling of multi-form by U-tube and pipe arrangement, forms the heat exchanger component of various different flow processs with this.
Shown in heat exchanger composition schematic diagram and different flow heat exchanger schematic diagram as accompanying drawing 1-1,1-2.
In accompanying drawing 1-1,1-2,1, U-tube；2nd, fin（Reserved circular hole）；3rd, end plate；4th, elbow；5th, isocon socket（It is interior
Slotting isocon, not shown in isocon figure）, 1,2,3,4,5 and isocon composition heat exchanger assembly.As accompanying drawing 1-1,1-2 justify
Shown in circle, U-tube carries out the combination assembling of multi-form with pipe arrangement, forms the heat exchanger component of various different flow processs with this.
Two class of isocon and elbow is mainly with the pipe arrangement of heat exchanger U-shaped pipe assembling.Wherein elbow and heat exchanger U-shaped pipe
Assembling standardization, it is relatively simple：Elbow is used uniformly across the material of caliber specification identical with heat exchanger U-shaped pipe, heat exchanger U-shaped pipe
The secondary expanding of tube expansion is carried out, now U-tube is just assembled, positioned and welded with elbow.U-tube is filled with elbow
Shown in schematic diagram as accompanying drawing 2：In figure, the heat exchanger U-shaped pipe of the secondary enlarging of 1-1, tube expansion；2nd, fin；3rd, end plate；4th, it is curved
Head.
Wherein isocon is complex with the assembling of heat exchanger U-shaped pipe.The effect of isocon is to be divided into cold-producing medium all the way
Two tunnels, three tunnels or more multichannel, thus isocon caliber be necessarily smaller than heat exchanger U-shaped pipe caliber.The assembling of isocon and U-tube,
Isocon is used uniformly across in industry at present carries out enlarging, beats positioning in flared section, then carries out with the heat exchanger U-shaped pipe after tube expansion
Assembling, positioning and welding.Shown in U-tube and isocon assembling schematic diagram as accompanying drawing 3：In figure, 1-2, the heat exchanger U of a tube expansion
Shape pipe；5-1, enlarging simultaneously beat the isocon of convex；5-2, convex.
In sum：Heat exchanger assembly processing method is used uniformly across in industry at present：Heat exchanger U-shaped pipe carries out a tube expansion
Secondary expanding, is assembled with elbow with this；Heat exchanger U-shaped pipe carries out a tube expansion processing, is carried out with isocon with this
Assembling.
The secondary enlarging technology of wherein described 1. tube expansion technique, 2. tube expansion, both processing methods are all once
Molding, both are different for swollen capitiform formula, and two kinds of swollen head schematic diagrams are as shown in accompanying drawing 4-1,4-2.
In figure, Fig. 4-1 is the swollen head of the secondary enlarging technology one-shot forming of tube expansion；Fig. 4-2 is a tube expansion with once
Molding is swollen head, wherein, a, a tube expansion section；B, secondary flared section；C, frock gripping section.
Above method can meet heat exchanger U-shaped pipe with shunting again due to solving the assembling of heat exchanger U-shaped pipe and elbow
The assembling demand of pipe and be widely used and become standard method.But the method there are problems that following at 2 points：
One：Heat exchanger assembly generalization standardization is low.The matched somebody with somebody size of heat exchanger of one casing be substantially it is fixed,
And flow process can change various with ability section difference, machine system configuration difference.Above method, on a heat exchanger it is existing with it is curved
The secondary enlarging U-tube of a tube expansion that head coordinates, has the tube expansion U-tube coordinated with isocon again.So, if flow process not
Equally, heat exchanger assembly is not just general, and as shown in accompanying drawing 1-1,1-2, therefore heat exchanger assembly generalization standardization is low.
Which two：Heat exchanger assembly manufacture efficiency is low.As described above, existing once swollen with what elbow coordinated on a heat exchanger
Secondary enlarging U-tube is managed, has the tube expansion U-tube coordinated with isocon, when thus carrying out tube expansion enlarging technique, electric tube expander again
Upper needs are according to heat exchanger flow process, while the swollen head of a tube expansion of the corresponding flow process of arrangement and the swollen head of the secondary enlarging of tube expansion, because
This, as long as heat exchanger flow process is different, it is necessary to suspend operation, re-starts swollen head arrangement, re-starts calibration, waste a large amount of
In man-hour, affect productive temp.As can be seen here, heat exchanger assembly manufacture efficiency is low.
At present, it is that U-tube is unified all using a tube expansion in heat exchanger assembly to solve problem above most powerful method
Secondary enlarging technique, this mode are fully solved that above heat exchanger assembly generalization standardization is low and manufacture efficiency is low asks
Topic.But the method there are problems that following at 2 points：
One：Isocon cannot be positioned.Due to isocon itself it is less than U-tube caliber, tube expansion of U-tube Jing and secondary
After enlarging, the caliber for increasing both is poor, causes isocon insertion U-tube position, and assembling quality cannot ensure that positioning is shown
It is intended to as shown in accompanying drawing 7-2.
Which two：Isocon welding quality is low.As described above, the U-tube caliber of the secondary enlarging of tube expansion is than isocon pipe
Footpath is much larger, the U-tube of the secondary enlarging of isocon tube expansion of insertion, and during welding, weld seam is too big, has both easily caused a large amount of overlaps
Flow in U-tube, form stifled weldering, easily cause insufficient solder connection again to shut big weld seam, form leak source, have a strong impact on welding quality
With the quality of air-conditioner, shown in weld seam schematic diagram as accompanying drawing 7-2.
Utility model content
A kind of problem that this utility model is present for prior art, there is provided air-conditioning heat exchanger assembly, can effective gram
