Embodiment
It refer to shown in Fig. 1 to Fig. 7, that show the concrete structure of the embodiment of the utility model；The concurrent flow
Heat exchanger inclining fin structure, can be widely applied to the fields such as air-conditioning, refrigerator, its structure design is simple, ingenious reasonable, significantly
Heat exchange property is improved, there is larger application value.
Direction terms such as " up, down, left, right, before and afters " specifically described herein describes, and is explained exemplified by shown in attached drawing, not
Make unique limit to direction.
Specifically, in this present embodiment, whole inclining fin structure is in rectangular configuration；The inclining fin structure includes
There are several oblique substrates 10 that spacing is set successively along the longitudinal direction, oblique 10 relative level of substrate tilts extension and sets
Put；In addition to the oblique substrate 10 of front and back ends (the oblique substrate 10 of front and back ends only have left end, one end in right end with it is adjacent
Oblique substrate connection), the left and right end of each oblique substrate 10 is corresponding to the oblique substrate 10 of adjacent forward and backward side respectively to be connected
To form S-shaped structure, herein, the left and right end of each oblique substrate 10 phase with the oblique substrate 10 of adjacent forward and backward side respectively
Answer and connected by arc panel 30 between end, such as：Semi-circular shape arc panel 30；Formed with upper and lower between adjacent oblique substrate 10
Groove 20 between extending obliquely out, it is described between groove 20 there is upper and lower end opening, it is described between the internal face of groove 20 vertically tilt extension and set
Put, in this way, reducing air drag（Result of the test shows that it at least reduces windage more than 25%）, can effectively force condensed water
Internal face along a groove 20 moves obliquely along air-flow direction, it is easy to is expelled directly out, draining is smooth, reduces and freezes now
As fin heat resistance reduces, and improves heat exchange efficiency, more energy saving, advantageously reduces cost.
It is at an acute angle in main view angle, the opposite anteroposterior direction extension axis of two oblique substrates 10 positioned at 20 both sides of a groove
Set, between the number range of preferably described acute angle is 25 degree to 35 degree, such as 30 degree.Two positioned at 20 both sides of a groove are oblique
Substrate 10 is set parallel to each other or is set each other in angle（With reference to shown in comparison diagram 5, Fig. 6 and Fig. 7）.
When two of 20 both sides of groove oblique substrates 10 are set parallel to each other between main view angle is located at, in depression angle, position
Also parallel each other in the top of two oblique substrates 10 of 20 both sides of a groove, the top of two oblique substrates 10 is vertical from a left side herein
It is extended to the right（As shown in Figure 5）Or setting is extended obliquely out from left to right（As shown in Figure 6）.
And applicant studies intensively the size characteristic of inclining fin, it is mainly from structural strength, easy processing
Property, the various aspects such as deformation resistance and product suitable dimensions parameter go to consider, obtain following reasonable ruler through multiple repetition test, analysis
Very little parameter designing：The whole height 8 of the inclining fin is to 8.03mm, the overall width 12mm of inclining fin, adjacent oblique base
The pitch of fins 1.7mm of plate, the thickness 0.08mm of oblique substrate.Some hollow out windows can be further offered on oblique substrate 10,
Certainly, hollow out window is that one is compressing on oblique substrate 10, and the design of hollow out window can play the role of increasing heat exchange area.
In general, the surface of hollow out window is provided with welding coating.
Next, substantially introduce the production process of foregoing inclining fin：After first carrying out right angle fin shaping, with inclination
The mould of fin carries out die mould shaping to former fin, reaches required fin shape；For fin caused by possibility after soldering
Deformation, can avoid deforming by way of increasing fin thickness and fin strength, therefore, the structural strength of inclining fin and
Anti-deformation performance etc. can be effectively ensured, and processing procedure is controllable reliable.
In conclusion the design focal point of the utility model is, it mainly passes through inclining fin structure design, reduces
Air drag, is more easy to discharge quick smooth guide of condensed water, reduces icing phenomenon, and fin heat resistance reduces, and improves heat exchange efficiency,
It is more energy saving, cost is advantageously reduced, meanwhile, when being also applied for outdoor and dusty occasion, it is not easy dust stratification dirt.
The above descriptions are merely preferred embodiments of the present invention, and not the technical scope of the utility model is made
Any restrictions, therefore every any trickle amendment made according to the technical essence of the utility model to above example, equivalent change
Change and modification, in the range of still falling within technical solutions of the utility model.
