Abstract
The utility model discloses and belong to relating to of automotive air-conditioning system components range a kind of parallel-flow evaporator base structure.Described base is that mould is squeezed into straight line hypomere and camber line epimere shape exists; Pipe end position limiting structure is in straight line hypomere one end, and header laminating plane one end of pipe end position limiting structure connects base lower end, and fixture plane one end of pipe end position limiting structure connects base upper end; Described header laminating plane and header plane fit.Compared with the base structure of base structure of the present utility model and prior art, simple in structure, reduce difficulty of processing, simplified assembly operation simultaneously.Optimize the positioning form of base in soldering.Increase the contact area of base and header, thereby increased the bonding area of soldering, improved weldering and rate, minimizing fault rate.The welding of header Manual flame weldering leak fraction defective by before 3.4% be reduced to present 0.01%.
Description
Technical field
The utility model belongs to automotive air-conditioning system components range.Be particularly related to a kind of parallel-flow evaporator base structure.
Background technology
Parallel-flow evaporator is the heat exchanger components in air-conditioning system, is made up of the header of going forward, upper rear header, lower front header, lower rear header, micro-channel flat, wing band and feed tube, escape pipe.The form that feed tube, escape pipe are connected with evaporator core body at present has a variety of, and most bases that use carry out transition, but the base complex structure using is difficult for processing, also makes the cylinder structure complexity of feed tube, escape pipe simultaneously.And in base welding process, be difficult for its location, welding quality is not bery desirable.
Utility model content
The purpose of this utility model is that the base complex structure using for prior art is difficult for processing, also make the deficiency of the cylinder structure complexity of feed tube, escape pipe that a kind of parallel-flow evaporator base structure is provided simultaneously, it is characterized in that, base is that mould is squeezed into straight line hypomere and camber line epimere shape exists; Pipe end position limiting structure 5 is in straight line hypomere one end, and header laminating plane 1 one end of pipe end position limiting structure 5 connects base lower end 2, and fixture plane 4 one end of pipe end position limiting structure 5 connect base upper end 3.
Described header laminating plane 1 fits with header plane,
Described base straight line hypomere is squeezed into Long Circle by circle and base camber line epimere keeps circular constant.
The utility model beneficial effect is above-mentioned base structure compared with the base structure of prior art, simple in structure, is easy to processing, is convenient to assembling, has reduced difficulty of processing and has simplified assembly operation simultaneously.Optimize the positioning form of base in soldering, increased the contact area of base and header; Base has formed Long Circle and circular transition region in extrusion modling, this region is for carrying out spacing to feed liquor, escape pipe, can play in Manual flame soldering by spacing feed liquor, the escape pipe of making, guarantee the length of lap joint, simplify the cylinder structure of feed liquor, escape pipe, and the welding point of Manual flame soldering is lap joint, thereby improve welding rate, reduced failure welding rate.

Detailed description of the invention
The utility model provides a kind of parallel-flow evaporator base structure, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
Fig. 1 is the perspective view of base.Fig. 2 is the planar structure schematic diagram of Fig. 1.Base in figure is that mould is squeezed into straight line hypomere and camber line epimere shape, and described base straight line hypomere is squeezed into Long Circle by circle and base camber line epimere keeps circular constant.Wherein pipe end position limiting structure 5 is in straight line hypomere one end, and header laminating plane 1 one end of pipe end position limiting structure 5 connects base lower end 2, and fixture plane 4 one end of pipe end position limiting structure 5 connect base upper end 3.
Concrete operations are as follows: header plane punching slotted hole matches with the slotted hole of base lower end.In assembling process, base lower end inserted in header slotted hole and make the header laminating plane 1 of base and the plane riveted joint laminating (as shown in Figure 3) of header 6; So just complete the location of base on header.Therefore removed from and entered the fixture of fixing base in stove brazing process, increased the area that base contacts with header simultaneously; During due to welding, feed liquor, escape pipe insert base upper end, have so just formed the lap joint of welding.Simultaneously due to the existence of position limiting structure in Fig. 15, feed liquor, escape pipe are inserted after base upper end in Manual flame brazing process not can play, has guaranteed the length of lap joint, has improved welding quality, has reduced failure welding rate.
