Disclosure of Invention

The above-mentioned problem to prior art exists, the utility model aims to solve the technical problem that a general type inner fin is provided to solve present inner fin and can not satisfy different length cooperations, produce the problem of cutting burr when the cutting easily.

In order to solve the technical problem, the utility model discloses a technical scheme be:

the utility model provides a fin in general type, includes guiding gutter, hole, fin body and cuts apart the groove, the guiding gutter both sides are provided with the fin body, evenly be provided with the hole on the fin body, hole corner sets up to the fillet, be provided with 3 cuts apart the groove on this interior fin, this interior fin divide into first interior fin, second interior fin, third interior fin and fourth interior fin, the bottom of cutting apart the groove is provided with the recess.

Further, the 3 dividing grooves are respectively arranged at 200mm, 250mm and 275mm of the width of the inner fin.

Further, the length of the dividing groove is consistent with the whole length of the inner fin.

Furthermore, grooves are formed in the upper portion and the lower portion of the base of the dividing groove, and the positions of the 2 grooves correspond to each other.

Further, the opening directions of the 3 dividing grooves are not uniform.

Further, the height of the dividing groove is consistent with the height of the fin body.

Has the advantages that: compared with the prior art, the method has the following advantages:

this fin in general type is provided with cuts apart the groove, and cuts apart the 200mm of fin including the position setting of groove, 250mm, 275mm department, and this interior fin has divided into 4 regions, and the user of service can cut apart interior fin according to specific actual conditions, and is simple and convenient, can satisfy the cooperation of fin in the different length, cuts apart the inslot simultaneously and is provided with the recess, makes this interior fin reduce a large amount of burrs in the cutting process, further assurance the quality of producing the piece.

FIG. 2 is a side view of a generic inner fin.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 and 2, the general inner fin of the present application includes a guiding groove 1, holes 2, a fin body 3 and dividing grooves 4, the fin body 3 is disposed on two sides of the guiding groove 1, the guiding groove 1 and the fin body 3 are uniformly disposed on the inner fin, the holes 2 are uniformly disposed on the fin body 3, the sizes of the holes 2 are the same, but the opening positions are different, heat dissipation can be performed to the maximum extent, corners of the holes 2 are set to be rounded corners, which means that fluid can better pass through the guiding groove 1, and simultaneously the guiding groove 1 and the holes 2 can be covered in all directions, without generating flow dead corners, the inner fin is provided with 3 dividing grooves 4, the inner fin is divided into a first inner fin 501, a second inner fin 502, a third inner fin 503 and a fourth inner fin 504, the width of the first inner fin 501 is 200mm, the width of the second inner fin 502 is 50mm, the width of the third inner fin 503 is 25mm, the width of the fourth inner fin 504 is 25mm, a user can cut the width of the inner fin according to specific practical conditions, the bottom end of the cutting groove 4 is provided with a groove 401, the groove 401 is arranged to improve cutting quality, and cutting burrs are reduced or even not generated.

3 division groove 4 set up respectively in 200mm, 250mm, 275mm departments of this interior fin width, divide into 4 regions to the interior fin, and user of service can open the width of cutting apart this interior fin according to specific actual conditions, convenient and fast.

The length of the dividing groove 4 is consistent with the whole length of the inner fin, so that the inner fin is ensured to be a whole, and meanwhile, even if the inner fin is not divided, the dividing groove 4 can also ensure that the inner fin cannot be broken or damaged in the using process.

All be provided with recess 401 about the base of segmenting groove 4, and the position of recess 401 is corresponding about the base, makes this interior fin more simple and convenient when cutting, reduces or even does not produce the cutting burr.

The opening directions of the 3 dividing grooves 4 are inconsistent, so that the strength and stability of the inner fin are guaranteed, and the correspondence of the inner fin when being divided is guaranteed.

The height of the dividing groove 4 is consistent with that of the fin body 3, so that the stability of the inner fin is ensured, and the dividing groove 4 which is not divided can also form a whole with the inner fin.

The utility model provides a thought and implementation method of fin in general type, the concrete application way is many, only above is the utility model discloses an optimal implementation mode should point out, to this technical field's ordinary skilled person, is not deviating from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements, these improvements should also be regarded as the utility model discloses a protection scope.
