Abstract
The invention discloses a parallel flow micro-channel heat exchanger. Each flow collecting pipe is of a double-layer composite structure, in other words, a brazing filler metal inner layer is composited inside an aluminum outer layer. Each flat pipe is constituted by a porous micropore pipe which is integrally formed through extrusion, and a zinc layer is applied to the surface of each flat pipe through spraying. Each fin is of a three-layer composite structure, in other words, the two side faces of each aluminum fin are each provided with a brazing filler metal layer in a composited manner. In the assembling process, an upper side plate and a lower side plate and the flat pipes are connected to the two flow collecting pipes in an inserted manner; the fins are clamped between each side plate and the corresponding flat pipe as well as between every two adjacent flat pipes; first fin wings at the two ends of each fin are closely attached to the flow collecting pipes; the rear side plate and the flat pipes are welded to the flow collecting pipes through furnace brazing; the ends of middle fin wings of the fins are welded to the side plates and the flat pipes; and the first fin wings at the two ends of each fin are welded to the flow collecting pipes. According to the parallel flow micro-channel heat exchanger, when furnace brazing is conducted, brazing filler metal does not flow onto the flat pipes; the corrosion phenomenon cannot happen to the flat pipes; after brazing is completed, the fins and the flow collecting pipes are in close contact; on the same windward face, the external effective heat exchange area is larger, so that wind passing through the heat exchanger is not leaked; it is helpful to improve heat exchange efficacy; and meanwhile, the parallel flow micro-channel heat exchanger is more attractive in appearance.
Description
Technical field
The invention belongs to technical field of heat exchangers, it is specifically related to a kind of concurrent flow micro-channel heat exchanger.
Background technology
In prior art, the application of concurrent flow micro-channel heat exchanger is more and more extensive, the cold-producing medium of flowing and sky in microchannel
Gas carries out heat exchange.Generally flat tube is made up of the porous microporous pipe of one extrusion molding, surface spraying zinc layers, not composite soldering layer；
Header is formed by welding using two layers of High Frequency Of Recombination, i.e. composite soldering outer layer on aluminium internal layer；Fin adopts three layers of compound height
Frequency is formed by welding, i.e. equal composite soldering layer on two sides of aluminium fin.When assembling product, header and fin two ends
Need to leave void layer between the first piece wing, prevented the solder of header appearance during slice weldering from flowing on flat tube by fin,
Lead to flat tube corrosion.Header and fin are not in close contact, and increased and leak out, and decrease the effective heat-transfer surface on windward side
Long-pending.
Content of the invention
The present invention mainly solves the technical problem existing for above-mentioned prior art, there is provided a kind of concurrent flow is micro- logical
Road heat exchanger, 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 concurrent flow microchannel
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 internal layer in aluminium outer layer；Described flat tube is made up of the porous microporous pipe of one extrusion molding, surface spraying zinc layers；
Described fin adopts three-layer composite structure, i.e. equal composite soldering layer on two sides of aluminium fin；Upper and lower two during assembling
Side plate and flat tube are plugged on two headers, clamp fin, fin two ends between side plate and flat tube and adjacent flat tube between
The first piece wing be close to header, cross slice postwelding side plate and flat tube be welded on header, the end weldering of the piece wing in the middle part of fin
It is connected on side plate and flat tube, the first piece wing at fin two ends 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.

Specific embodiment
Below by embodiment, and combine accompanying drawing, technical scheme is described in further detail.
Embodiment：Referring to Fig. 1, a kind of concurrent flow micro-channel heat exchanger, including two headers be arrangeding in parallel, two collection
It is plugged with some flat tubes and upper and lower two side plates between flow tube, between side plate and flat tube, be clamped with fin and adjacent flat tube between, collection
Flow tube is provided with water inlet pipe and outlet pipe, and wherein water inlet pipe arranges the lower end of header, and outlet pipe is arranged on collection via adapter
On the tube wall on flow tube top, header also sets up between installation, heat exchanger can be fixed on wall via mounting bracket
On plate or bearing.Described header adopts two layers of composite construction, i.e. composite soldering internal layer in aluminium outer layer；Described flat tube is by one
The porous microporous pipe of body extrusion molding is constituted, surface spraying zinc layers；Described fin adopts three-layer composite structure, that is, in aluminium fin
Two sides on equal composite soldering layers；During assembling, upper and lower two side plates and flat tube are plugged on two headers, side plate with
Clamp fin between flat tube and adjacent flat tube between, the first piece wing at fin two ends is close to header, cross slice postwelding side plate and
Flat tube is 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 wing weldering at fin two ends
It is connected 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
