Abstract
The utility model discloses and belong to a kind of automobile air conditioner parallel flow formula condenser dividing plate that core body used for automobile air conditioning manufactures field.This dividing plate is each welding stationary jaw in the both sides symmetry of a full circle sheet; Described dividing plate is mounted to the septalium position of header, and the stationary jaw of dividing plate both sides is coordinated tightly with septalium, and on dividing plate, two stationary jaws are radially pressed on the wall of header.Thus dividing plate and header are pressed together.The utility model diaphragm structure is simple, easy to manufacture, improves the assembling of dividing plate and header, is beneficial to carrying out smoothly of furnace brazing, effectively can reduce the probability of this position leakage of refrigerant.
Description
Technical field
The utility model belongs to core body used for automobile air conditioning and manufactures field.In particular to a kind of automobile air conditioner parallel flow formula condenser dividing plate.
Background technology
Cocurrent flow type condenser (Fig. 2) is the important composition parts in air-conditioning refrigeration system, by header (2), micro-channel flat (4), wing band, backplate (3), air inlet pressing plate (1), goes out hydraulic plate (5), dividing plate (6), sealing cap etc. and forms.Cold-producing medium enters core body inside by air inlet pressing plate (1), and due to the effect of damming of dividing plate, path along arrow mark in figure is completed the transformation of cold-producing medium phase in core body internal flow by cold-producing medium.The dividing plate that current cocurrent flow type condenser uses is made up of size two halfround bar slices, not good with header fiting effect, causes welding quality undesirable, leaks, reveals in easily occurring.
Dividing plate (Fig. 1) Problems existing that present stage uses is comparatively outstanding, mainly contains:
1. dividing plate lacks location structure, and in the process of same header assembling, dividing plate easily occurs along header axis " rotation " phenomenon, causes assembling lack of standardization, and then causes leakage in core body;
2. dividing plate lacks fastening structure, the core body do not welded in carrying, enter in stove welding process, easily occur getting loose, shifting phenomena, have a strong impact on the welding quality of core body;
3. dividing plate and header cooperation place are unfavorable for sprawling smoothly of solder, have higher slip.
Utility model content
The purpose of this utility model provides a kind of automobile air conditioner parallel flow formula condenser dividing plate for the failure welding problem existed in present stage core body manufacture process, it is characterized in that, this dividing plate is each welding stationary jaw in the both sides symmetry of a full circle sheet;
Described dividing plate is mounted to the septalium position of header, and the stationary jaw of dividing plate both sides is coordinated tightly with septalium, and on dividing plate, two stationary jaws are radially pressed on the wall of header.
The beneficial effects of the utility model are that the utility model provides a kind of diaphragm structure being convenient to assemble, be beneficial to welding, and contribute to the welding quality promoting condenser core, tool has following features:
1. the stationary jaw of dividing plate and header closely cooperate, and have increased considerably the fastness of dividing plate, before avoiding welding, welding time the dividing plate that produces get loose, be shifted.
2. the increase of dividing plate radial dimension is conducive to reducing the fit clearance between dividing plate and header, and contribute to sprawling smoothly of solder, reduce the slip of core body, product quality is improved simultaneously.
3. stationary jaw also can be used for assembling and positioning, by the attitude of visual claw, assembly crewman can confirm whether dividing plate is seated intuitively, significantly reduces the probability leaking in core body and occur.

Detailed description of the invention
The utility model provides a kind of automobile air conditioner parallel flow formula condenser dividing plate, is described in detail detailed description of the invention of the present utility model below in conjunction with accompanying drawing:
In the dividing plate schematic diagram of the improvement shown in Fig. 3, its dividing plate is each welding stationary jaw 7 of the dividing plate 6 both sides symmetry at a full circle sheet;
Cocurrent flow type condenser core body schematic diagram shown in Fig. 2, in figure: the parallel endways fixing header 2 in condenser core both sides, the upper and lower side of header 2 fixes backplate 3, equidistant weldering micro-channel flat 4 between two backplates 3; Air inlet pressing plate 1 is fixed on header 2 top; Header 2 bottom fixedly goes out hydraulic plate 5; Dividing plate 6 snaps in the septalium 8 of header, and the stationary jaw 7 of dividing plate both sides coordinates tightly with septalium 8, and on dividing plate 6, two stationary jaws 7 are radially pressed on (as shown in Figure 4,5) on the wall of header 2.
The parallel flow condenser dividing plate 6 of the present embodiment coordinates with header 2, and it is fixing to carry out pressurization by dividing plate stationary jaw 7.Specific as follows:
Header 2 is aluminum, and outer surface has one deck composite bed, and when this composite bed welds in stove, melting is for liquid, carries out weld seam filling as solder.Header there is semicircular septalium (Fig. 4).Dividing plate is alumiaum article, punch forming, and two surfaces are all with composite bed.In assembling process (Fig. 5), first dividing plate is inserted in septalium, then compress and dividing plate is coordinated closely with header inwall under pressure.Then take out header, rap the stationary jaw 7 (as Fig. 3,4,5) of dividing plate both sides with hand hammer, stationary jaw 7 is coordinated closely with header 2 outer wall.Such process effectively can be avoided carrying, enter in stove brazing process, the problems such as dividing plate gets loose, displacement.The cooperation place of this external partition and header can produce larger capillary pulling power, during welding, composite bed on header appearance and dividing plate melts, the liquid solder of melting is assembled to dividing plate place under the effect of capillary pulling power, be beneficial to the filling of weld seam, make layer even, solder joint is full, significantly reduces the core body leakage that dividing plate failure welding causes.
