Abstract
The invention discloses a water cooled type parallel flow heat exchanger. Each header pipe adopts a double-layer composite structure, namely a solder outer layer is compounded on the inner layer of an aluminum material; each fin adopts the double-layer composite structure, namely a solder layer is compounded on one side surface of each fin of the aluminum material; each flat pipe adopts a three-layer composite structure, namely a solder outer layer is compounded outside the middle layer of the aluminum material, and an anticorrosive layer is compounded inside the middle layer of the aluminum material. During assembly, an upper side plate, a lower side plate and the flat pipe are inserted into two header pipes; fins are clamped between the side plate and the flat pipe and between adjacent flat pipes; the solder layers of first wings at the two ends of the fins cling to the header pipes; after brazing in a furnace, the end parts of the middle wings of the fins are welded on the side plates and the flat pipes; the first wings at the two ends of the fins are welded on the header pipes. According to the water cooled type parallel flow heat exchanger disclosed by the invention, the solder does not flow on the flat pipes during brazing in the furnace, so the flat pipes are free from dissolution corrosion; after brazing, the fins are in close contact with the header pipes; the external effective heat exchange area is larger on the same wind receiving surface, so the wind passing through the heat exchanger is not leaked, improvement of heat exchange efficiency is facilitated, and meanwhile the heat exchanger is more beautiful in appearance.
Description
Technical field

Background technology
In prior art, the inside water flowing of water-cooled parallel-flow heat exchanger and air carry out heat exchange, and usual header adopts
Two layers of High Frequency Of Recombination are formed by welding, i.e. composite soldering outer layer on aluminium internal layer；Fin is individual layer aluminium, not composite soldering layer.
When assembling product, need to leave void layer between header and the fin two ends first piece wing, prevented header during slice weldering
The solder of appearance is flowed on flat tube by fin, leads to flat tube corrosion.Header and fin are not in close contact, and increased leakage
Wind, decreases the effective heat exchange area on windward side.
Content of the invention
The present invention mainly solves the technical problem existing for above-mentioned prior art, there is provided a kind of water-cooled concurrent flow changes
Hot device, header and fin can be in close contact, and decrease and leak out, and increased the effective heat exchange area on windward side.
The above-mentioned technical problem of the present invention is mainly addressed by following technical proposals：A kind of water-cooled concurrent flow
Heat exchanger, including two headers be arrangeding in parallel, is plugged with some flat tubes and upper and lower two side plates, side plate between two headers
It is clamped with fin between flat tube, header is provided with water inlet pipe and outlet pipe, wherein water inlet pipe setting and adjacent flat tube between
The lower end of header, outlet pipe is arranged on the tube wall on header top via adapter, header also sets up between installation,
Heat exchanger can be fixed on wallboard or bearing via mounting bracket.Described header adopts two layers of composite construction, that is,
Composite soldering outer layer on aluminium internal layer；Described fin is also adopted by two layers of composite construction, that is, on a side of aluminium fin
Composite soldering layer；Described flat tube adopts three-layer composite structure, that is, in the outside composite soldering outer layer in aluminium intermediate layer, in aluminium
The inside anticorrosion layer of interbed；During assembling, upper and lower two side plates and flat tube are plugged on two headers, side plate with flat
Fin is clamped and adjacent flat tube between, the solder layer of the fin two ends first piece wing is close to header, is crossed slice postwelding side between pipe
Plate and flat tube are welded on header, and in the middle part of fin, the end of the piece wing is welded on side plate and flat tube, the first piece at fin two ends
The wing is welded on header.
When the present invention crosses slice weldering, solder does not flow on flat tube, and flat tube also would not produce corrosion phenomenon, soldering hind wing
Piece and header are in close contact, and on equal windward side, outside effective heat exchange area is bigger, makes not let out by the wind of heat exchanger
Leakage, beneficial to improving heat exchanger efficiency, outward appearance is more attractive in appearance simultaneously.Therefore, the present invention have structure simple, reasonable in design the features such as.
