Abstract
It the utility model is related to a kind of coating end socket pipe heat exchanger, parallel cooling duct is provided with one-time formed extruded tube, fin is provided between each two extruded tube, end socket is provided with the end of fin, end socket is U-shape structure, and the upper and lower surface of end socket extrudes pipe surface soldering connection with corresponding respectively.The heat exchanger uses one-shot forming extruded tube, reduces solder side so as to reduce leakage, improves product quality.
Description
Technical field
A kind of coating end socket pipe heat exchanger is the utility model is related to, belongs to plate-fin heat exchanger field.
Background technology
Used it is well known that plate-fin heat exchanger is usually used in vehicle intercooler, air compressor heat exchange and machine oil heat exchange.It is this kind of
Plate-fin heat exchanger generally includes short strip of paper used for sealing, long strip of paper used for sealing, inner fin, outer fin and dividing plate composition.As shown in figure 1, adjacent two
Partition room places fin, inner fin and strip of paper used for sealing and forms an interlayer, referred to as passage, is folded outer fin is laid on the outside of such interlayer
Put, short strip of paper used for sealing is installed in end, is welded to form plate beam by vacuum brazing, plate beam is the core of plate-fin heat exchanger, is equipped with
Necessary supporting plate, end cap, adapter etc. just constitute plate-fin heat exchanger.This kind of structure plate-fin shortcoming be it is complicated, by
The brazing surface of dividing plate and end socket composition passage is excessive, and soldering control difficulty is big, often occurs leakage point after soldering, and maintenance is not allowed relatively
Easily.And due to factors such as material, techniques, this kind of structure plate-fin heat exchanger soldering is can only to use vacuum brazing, cost is high,
Efficiency is low.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of coating end socket pipe heat exchanger, and the heat exchanger uses one
Secondary Contoured squeeze pipe, solder side is reduced so as to reduce leakage, improves product quality.
To solve problem above, concrete technical scheme of the present utility model is as follows：A kind of coating end socket pipe heat exchanger, one
Parallel cooling duct is provided with the extruded tube of secondary shaping, fin is provided between each two extruded tube, is provided with the end of fin
End socket, end socket are U-shape structure, and the upper and lower surface of end socket extrudes pipe surface soldering connection with corresponding respectively.
The U-shaped opening of described end socket is inwardly set, and U-shaped surfaces externally and internally is equipped with solder coating.
The coating end socket pipe heat exchanger uses one-shot forming extruded tube, reduces solder side so as to reduce leakage, improves production
Quality, while U-shaped end socket is used, the compactness of end socket and extruded tube is added, so as to avoid snapping the generation of phenomenon.
End socket is inside using U-shaped opening, does not influence the overall appearance of heat exchanger, while utilize the solder of end socket surfaces externally and internally
Coating, continous way nitrogen soldering is realized, improve soldering efficiency, reduce technology difficulty.

Fig. 1 is common plate-fin heat exchanger structural representation.
Fig. 2 is coating end socket pipe heat exchanger structural representation.
Fig. 3 is end enclosure structure schematic diagram；
Wherein 1 it is fin, 2 be extruded tube, 3 be end socket, 4 be heat-radiation belt, 5 be dividing plate, 6 be inner fin, 7 is short end socket, 8
For long strip of paper used for sealing.
Embodiment
As shown in Fig. 2 a kind of coating end socket pipe heat exchanger, one-time formed extruded tube（2）It is interior to be provided with parallel cooling
Passage, passage employ extruded tube structure, reduce bonding area, reduce the leakage after soldering；Each two extruded tube（2）It
Between be provided with fin（1）, in fin（1）End be provided with end socket（3）, end socket（3）For U-shape structure, U-shaped opening is inwardly set, and U
Type surfaces externally and internally is equipped with solder coating, end socket（3）Upper and lower surface respectively with it is corresponding extruding pipe surface soldering connection.Extruding
After pipe 2 laminates placement in certain sequence with fin, the end socket of U-shape structure（3）Fully contacted with extruding pipe surface, so as to ensure that
Continuous Welding.
