Any point and be moved into third orientation C in, the main body 84 of the first cooling fin 81 is formed with first surface in this orientation
Second jiao 200, preferably such as demonstrated in Figure 9 is 90 degree.Continue by this method, it may be appreciated that, cut the continuous propulsion of blade 302
Can a cooling fin be generated in the first or second orients A, B simultaneously, while the cooling fin straightening previously cut being determined to third
To C, and the last one cooling fin in described group of cooling fin 80 can be by 306 straightening of cooling fin straightener, without with blade 302
Cut any extra heat dissipation piece.It will be understood that although the first and second orientations explanation is, in identical acute angle, situation need not
So.Although having been described as being in 90 degree in addition, third orients, it will be understood that, it can be only than the first orientation through " straightening " orientation
Directly.
In Figure 10, first embodiment according to the present invention shows one group of complete cooling fin 80.The main body 84 of cooling fin 80
An angle of 90 degrees is formed with the first surface 62 for the metal master 60 that radial inward extends when being assembled on annular backward shell 52.
In fig. 11, one group of complete cooling fin 80 is shown according to the second embodiment of the present invention.Second embodiment is similar
In first embodiment；Therefore, similar portion will add 100 to identify with similar number, also, it is to be understood that unless otherwise noted,
Otherwise second embodiment is suitable for the description of the similar portion of first embodiment.It is expected that the class with cutting blade and straightener
One group of cooling fin 180 can be formed from the upper surface of metal master 160 162 like cutting machines, wherein cooling fin 180 can have such as institute
The bow-shaped cross-section shown.
During the operation of surface-cooler 50 (Fig. 1), such as the hot fluids such as oil are close to upper surface 62 and pass through fluid
Cooling channel 70.Heat from fluid can be conducted through metal master 60, and can be dissipated to seriously via described group of cooling fin 80
Cross the cooling fluid of cooling fin 80.Cooling fluid may include cooling air of the (but not limited to) by annular access 36, the ring
Shape access 36 is by means of the bypass duct that non-limiting examples can be turbogenerator 10.
Embodiments described above realizes a variety of benefits, including can rate more faster than traditional cutting process formed it is scattered
Backing；In an example, current method per minute while being moved to cooling fin in the second orientation B can form 250
Cooling fin.In addition, the use of cutting process allows compared with such as other manufacturing methods such as mechanical processing in cooling fin 80
Less material is used during formation, this can reduce the material cost of surface-cooler 50.Current method also allows from including pre- shape
At the extrded material of fluid cooling channel 70 cut cooling fin, this fluid being attributable in cooling channel 70 is mobile and improves
The hot property of surface-cooler 50.
In addition, cooling fin 80 can be durable enough to use the mark such as annular saw or other Grinding structural units formed by cutting
Quasi- tool adjustment position or shape include that cooling fin 80 is remolded shape by the desired locations based on 10 inner surface cooler 50 of engine
For arch or conical type face.The durability of cooling fin 80 can also be improved for touching from such as various sources such as foreign object clast
The bad resistance of damage.
It should also be clear that the surface-cooler with the cooling fin being integrally formed by parent materials such as such as metal masters can have
There is heat transfer coefficient more higher than surface-cooler with the cooling fin for being connected to parent material by various known bindiny mechanisms,
And above-described embodiment can realize to be made more efficiently have the surface for the integrally formed cooling fin for possessing preferable cooling capacity cold
But device.In addition, embodiments described above can be easier, repeatable and more reliable, this allows under predictable interval
Predictable cooling fin geometry.
In the degree not yet described, the different characteristic and structure of various aspects can be used in combination with other as needed.
One feature middle in all respects cannot illustrate to be not meant to be interpreted to illustrate the feature, but be retouched in order to simplified
It states and does not just specify.Therefore, the various features of different aspect can be mixed and matched as needed to form new aspect, regardless of newly
Whether aspect is expressly depicted.The present invention covers the combination or arrangement of features described herein.
This written description discloses the present invention, including optimal mode using example, and also so that the technology of fields
Personnel can implement the present invention, including manufacture and use any device or system and execute any be incorporated to method.This hair
Bright patentable scope is defined by the claims, and may include those skilled in the art expected it is other
Example.If such other examples have not different from claims literal language structural element, or if they
Include with equivalent structural elements of the literal language of claims without essence difference, then they are both scheduled on claims
In range.
