Description
Technical field
The present invention relates to technical field of heat exchangers, more particularly to one kind insert swollen finned heat exchanger D type swelling techniques and
It inserts swollen finned heat exchanger.
Background technology
At present the refrigeration plant such as refrigerator, refrigerator with insert expanding finned heat exchanger be mostly bent heat exchanger tube insertion interference
Fin slotted eye, be adjacent to the slotted eye of heat exchanger tube and fin, so as to form completely slotting expanding finned heat exchanger.But actually change
It is dynamic fit when heat pipe is inserted through fin slotted eye, due to being influenceed by fin precision and the straight degree of heat exchanger tube, the slotted eye of fin exists
This process occurs to expand and stress deformation, fin slotted eye can not be adjacent to completely after heat exchanger tube is inserted through with heat exchanger tube, so
Fin and heat exchanger tube are loose fit mostly, effective heat transfer of fin and heat exchanger tube are weakened, so as to have impact on heat exchange property.
The content of the invention
The technical problems to be solved by the invention are：In order to overcome deficiency of the prior art, the present invention provides a kind of insert
Swollen finned heat exchanger D type swelling techniques and its slotting swollen finned heat exchanger.
The present invention solves its technical problem technical scheme to be taken：One kind inserts swollen finned heat exchanger D type swellings
Technique, comprise the following steps, the technique that secondary swelling is carried out on the basis of former slotting expanding finned heat exchanger, the secondary swelling
Including making heat exchanger tube be deformed from circle to D types by the swollen technique of D-shaped, in the process, the flat of D types is presented in inner side for heat exchanger tube
Face, and outside and the position of fin contacts outwards expand increase deformation, heat exchanger tube is contacted with fin slotted eye even closer, so as to
Improve the heat-exchange capacity of heat exchanger tube and fin.
Further, in addition to the swollen cutting of D types, cutting fixed seat, swollen product and product fixed seat is treated, the swollen cutting of D types is consolidated
It is scheduled in cutting fixed seat, meanwhile, it will treat that swollen product is fixed in product fixed seat, driving cutting fixed seat makes the swollen cutting of D types
The inner side of the heat exchanger tube in the fin slotted eye of swollen product is treated in insertion, and cutting that D types are swollen makes to change outwardly against the heat exchanger tube for treating swollen product
Heat pipe is deformed from circle to D types.Cutting that D types are swollen, cutting fixed seat, treat that swollen product and product fixed seat forms the swollen slotting swollen machine of D types
The primary structure of system.
Further, the swollen cutting of D types includes cutting body, and the front end of the cutting body is pyramidal structure, the cone
Swollen head is arranged with the cutting body of shape structure both sides, the distance between distal end of swollen head A is more than same fin described in both sides
The distance between heat exchanger tube in slotted eye B.Tapered front end is facilitated insertion into fin slotted eye, makes heat exchange by the interference extrusion of swollen head
Pipe produces the deformation of D types.
Swollen head can take various forms, as long as the purpose of interference extrusion deformation can be realized.But in order to reduce
Frictional force, avoid damaging fin slotted eye, swollen head profile of the invention uses circular arc, and the height of swollen head is not more than fin groove
The width in hole, avoid blocking.
A kind of mode, the swollen head are the strip bulge being fixed on the cutting body, the strip bulge cross section
Outer contour be arc.Swollen head is directly fixed on the side of cutting body, Huo Zhe using the part cylindrical axially cut
When processing cutting body, strip bulge is integrally machined out.
Another way, the swollen head are the cylindrical roller being rotatably connected on the cutting body, the cylindricality roller segment
Positioned at the cutting body interior, part is outwardly in the surface of the cutting body.Will using the swollen head of the cylindrical roller of rotation
The resistance for being converted into and rolling when reducing intubation is slided, reduces the flexural deformation of fin slotted eye.
One kind inserts swollen finned heat exchanger, using the D type swelling techniques of above-mentioned slotting swollen finned heat exchanger, including it is multiple
Fin and heat exchanger tube, the fin are provided with fin slotted eye, and the heat exchanger tube is plugged in the fin slotted eye, and the heat exchange
The cross section of pipe is D types, and the D types heat exchanger tube includes planar portions and curved portions, and the planar portions are located at inner side, the curved portions
Contacted positioned at outside with the fin slotted eye.
The beneficial effects of the invention are as follows：One kind provided by the invention is inserted swollen finned heat exchanger D type swelling techniques and its inserted
Swollen finned heat exchanger, D type swelling techniques of the invention are that increase D types are swollen on the basis of former slotting swollen heat exchanger, make to change
Heat pipe produces the deformation of D types, and inner side plane, outside play drum expansion, the swelling degree of increase heat exchanger tube and fin slotted eye, while heat exchanger tube
Also it is more straight, the heat exchange property of finned heat exchanger is on the one hand improved, on the other hand also improves the outward appearance of product.
