Abstract
A kind of concurrent flow micro-channel heat exchanger, header is using two layers of composite construction, i.e., the composite soldering internal layer in aluminium outer layer；Flat tube is made up of the porous microporous pipe of integral extrusion forming, surface spraying zinc layers；Fin uses three-layer composite structure, i.e., the equal composite soldering layer on two sides of aluminium fin.Two side plates and flat tube are plugged on two headers above and below during assembling, between side plate and flat tube fin is clamped between adjacent flat tube, first wing at fin two ends is close to header, cross slice postwelding side plate and flat tube is welded on header, the end of the piece wing is welded on side plate and flat tube in the middle part of fin, and first wing at fin two ends is welded on header.Solder is not flowed on flat tube when the utility model crosses slice weldering, flat tube would not also produce corrosion phenomenon, fin and header are in close contact after soldering, outside effective heat exchange area is bigger on equal windward side, make not leak by the wind of heat exchanger, beneficial to heat exchanger efficiency is improved, while outward appearance is more attractive in appearance.
Description
Technical field
The utility model belongs to technical field of heat exchangers, is specifically related to a kind of concurrent flow micro-channel heat exchanger.
Background technology
In the prior art, the application of concurrent flow micro-channel heat exchanger is more and more extensive, the refrigerant flowed in microchannel and sky
Gas is exchanged heat.Usual flat tube is made up of the porous microporous pipe of integral extrusion forming, surface spraying zinc layers, not composite soldering layer；
Header is formed by welding using two layers of High Frequency Of Recombination, i.e., the composite soldering outer layer on aluminium internal layer；Fin is using three layers of compound height
Frequency is formed by welding, i.e., the equal composite soldering layer on two sides of aluminium fin.When assembling product, header and fin two ends
Need to leave void layer between first wing, prevented the solder of header appearance when slice is welded from being flowed to by fin on flat tube,
Cause flat tube corrosion.Header and fin are not in close contact, and are added and are leaked out, and reduce effective heat-transfer surface on windward side
Product.
The content of the invention
The utility model is mainly the technical problem that solves present in above-mentioned prior art, and there is provided a kind of concurrent flow
Micro-channel heat exchanger, header and fin can be in close contact, and reduced and leaked out, and add the effective heat exchange area on windward side.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：A kind of concurrent flow is micro-
Some flat tubes and up and down two side plates are plugged between channel heat exchanger, including two headers be arrangeding in parallel, two headers,
Fin is clamped between side plate and flat tube between adjacent flat tube, header is provided with water inlet pipe and outlet pipe, wherein water inlet pipe
The lower end of header is set, and outlet pipe is arranged on via adapter on the tube wall on header top, and installation is also set up on header
Between, heat exchanger can be fixed on wallboard or bearing via mounting bracket.The header is using two layers of composite junction
Structure, i.e., the composite soldering internal layer in aluminium outer layer；The flat tube is made up of the porous microporous pipe of integral extrusion forming, surface spraying
Zinc layers；The fin uses three-layer composite structure, i.e., the equal composite soldering layer on two sides of aluminium fin；Above and below during assembling
Two side plates and flat tube are plugged on two headers, and fin, fin are clamped between adjacent flat tube between side plate and flat tube
First wing at two ends is close to header, crosses slice postwelding side plate and flat tube is welded on header, the end of the piece wing in the middle part of fin
Portion is welded on side plate and flat tube, and first wing at fin two ends is welded on header.
Solder is not flowed on flat tube when the utility model crosses slice weldering, and flat tube would not also produce corrosion phenomenon, soldering
Fin and header are in close contact afterwards, and outside effective heat exchange area is bigger on equal windward side, makes not having by the wind of heat exchanger
There is leakage, beneficial to heat exchanger efficiency is improved, while outward appearance is more attractive in appearance.Therefore, the utility model has simple in construction, reasonable in design
The features such as.

Flow tube is provided with water inlet pipe and outlet pipe, and wherein water inlet pipe sets the lower end of header, and outlet pipe is arranged on collection via adapter
Also set up on the tube wall on flow tube top, on header between installation, heat exchanger wall can be fixed on via mounting bracket
On plate or bearing.The header is using two layers of composite construction, i.e., the composite soldering internal layer in aluminium outer layer；The flat tube is by one
The porous microporous pipe of body extrusion forming is constituted, surface spraying zinc layers；The fin uses three-layer composite structure, i.e., in aluminium fin
Two sides on equal composite soldering layer；Two side plates and flat tube are plugged on two headers above and below during assembling, side plate with
Clamp fin between flat tube between adjacent flat tube, first wing at fin two ends is close to header, cross slice postwelding side plate and
Flat tube is welded on header, and the end of the piece wing is welded on side plate and flat tube in the middle part of fin, first wing weldering at fin two ends
It is connected on header.
Solder is not flowed on flat tube when the utility model crosses slice weldering, and flat tube would not also produce corrosion phenomenon, soldering
Fin and header are in close contact afterwards, and outside effective heat exchange area is bigger on equal windward side, makes not having by the wind of heat exchanger
There is leakage, beneficial to heat exchanger efficiency is improved, while outward appearance is more attractive in appearance.Therefore, the utility model has simple in construction, reasonable in design
The features such as.
Finally it is pointed out that above example is only the more representational example of the utility model.Obviously, this practicality is new
Type is not limited to above-described embodiment, can also there is many deformations.It is every according to technical spirit of the present utility model to above example
