Description
Technical field
The present invention relates to a kind of welded tube evaporator fin and its manufacture method, especially suitable for being used on large refrigerator.
Background technology
In modern refrigerator industry, evaporator fin is a kind of common wind-cooled evaporator structure, because it is in wind-force
Effect is lower to realize heat exchange, uniform due to exchanging heat, therefore is widely used in large refrigerator, so air cooling fin evaporator is a kind of
Indispensable refrigeration accessory.
In the prior art, evaporator fin is divided into auxetic evaporator and two kinds of evaporator fin of push-in by processing method.Draw
Swollen evaporator is that metal tubes first are penetrated into punching to have in the fin of perforation hole, then stretches into auxetic metal in metal tubes with swollen head
Pipeline so that the pipeline and fin that caliber increases after bulging are interference fitted and fixed.Evaporator fin is pushed into, is by hole punch
Fin is put into mould fixed, and then hardness is more than in the metal tubes push-in fin hole of fin hardness, and by pipe and
The interference fit in hole and fix.Both processing modes, although being all by interference fit, metal tubes and fin is set closely to match somebody with somebody
Close, but this fit system does not ensure that the good contact of pipe and fin, because following 2 points：Firstly, since
There are many fins on the same root pipe of evaporator fin, either tube expansion is still pushed into the interference fit of formation, is all whole
The interference fit of metal tube and multi-disc fin, pipe it is any not straight, the deformation of any one fin or with metal tube
Out of plumb, other fins can be all caused to reach fixed with the non-good contact of metal tube.As can be seen here, both fins steam
Hair device metal tube and fin can not realize good contact, therefore can influence the heat exchanger effectiveness of evaporator fin.
The content of the invention
The task of the present invention is to propose that a kind of pipeline and fin are integrated, and heat exchanger effectiveness height is so as to meeting different refrigeration
A kind of welded tube evaporator fin and its manufacture method of rate request.
The task of the present invention, which is done in such a way that, is characterized in that：Fin is by a clad aluminium punching with solder
Form, there is stamping forming fin hole in the front of the fin, stretch out after the fin back side is stamped tapered pipe with it is adjacent
Fin joins end to end, be connected after conical pipe form can make liquid flow pipeline, the pipeline both ends be provided with closure and with
Adjacent tubes are linked to be path.It is the cavity container of closing inside the closure, the pipe fin assembled is put into pricker with clamp
Brazier, the clad aluminium with solder fuses welding fabrication at high temperature, and after coming out of the stove, then the initial end installing pipe of pipeline forms welded tube
Fin evaporates.The line end external diameter is less than fin left end hole internal diameter.Make the process of welded tube evaporator fin：
The first step：By punching on the clad aluminium with solder, the clad aluminium after punching is in fin plate body；
Second step：The fin plate body front punching press pore-forming, the stamped back edge in the back side stretch out tapered pipe；
3rd step：The fin plate joins end to end with adjacent fin plate, and conical pipe is concentric after being connected, and composition can flow liquid
To pipeline；
4th step：The pipeline both ends, which are loaded on, to be blocked and is linked to be path with adjacent pipeline；
5th step：The pipe fin assembled is put into soldering oven, and the clad aluminium with solder fuses welding fabrication at high temperature；
6th step：After coming out of the stove, then connecting tube of burn-oning, form this welded tube evaporator fin.
The present invention has the following effects that：The technical program is that fin and pipeline are formed by welding into one by connector, pipe
The thermal resistance of son and fin substantially reduces so that the heat exchanger effectiveness of evaporator fin significantly improves, and can meet different
The requirement of cooling rate.

Drawing explanation：1st, fin, 2, closure, 3, pipeline, 4, connecting tube, 1-1, fin hole, 1-2, conical pipe.
Embodiment
Evaporator fin made of the technical program, pipeline be the extension being washed into by each fin be connected in series through welding and
Into fin is one with pipeline, therefore the thermal resistance of pipe and fin substantially reduces so that the heat exchanger effectiveness of fin evaporation tube is obvious
Improve, overcome existing auxetic evaporator fin and push-in evaporator fin fin and pipe contacts the defects of bad.
As depicted in figs. 1 and 2, fin 1 is formed by a clad aluminium punching with solder to specific embodiment, the wing
There is stamping forming fin hole 1-1 in the front of piece, and stretch out tapered pipe and adjacent fins head and the tail after the fin back side is stamped
Be connected, be connected after conical pipe 1-2 form can make liquid flow pipeline 3, the pipeline both ends be provided with closure and with it is adjacent
Pipeline is linked to be path, is the cavity container of closing inside the closure 2, and the pipe fin assembled is put into soldering with clamp
Stove, the clad aluminium with solder fuses welding fabrication at high temperature, after coming out of the stove, is formed from the initial end installation connecting tube 4 of pipeline
Welded tube evaporator fin, the line end external diameter are less than fin left end hole internal diameter.
The embodiment of another fin, coated with solder is not needed on clad aluminium, closed conical pipe and fin using welding
It is integrated.
As the improvement of the present invention, on the clad aluminium punching form fin plate, can rush two or two on clad aluminium
Fin hole more than individual, it is therefore an objective to the two or more pieces pipeline as shown in 7 can be formed, meet wanting for different refrigerating efficiencies
Ask, and can be according to the fin for needing to select different sizes of refrigeration.
Make the process of welded tube evaporator fin：
The first step：By punching on the clad aluminium with solder, the clad aluminium after punching is in fin plate body；
Second step：The fin plate body front punching press pore-forming, the stamped back edge in the back side stretch out tapered pipe；
3rd step：The fin plate joins end to end with adjacent fin plate, and conical pipe is concentric after being connected, and composition can flow liquid
To pipeline；
4th step：The pipeline both ends, which are loaded on, to be blocked and is linked to be path with adjacent pipeline；
5th step：The pipe fin assembled is put into soldering oven, and the clad aluminium with solder fuses welding fabrication at high temperature；
6th step：After coming out of the stove, then connecting tube of burn-oning, form this welded tube evaporator fin.
