Description
Technical field
The utility model relates to a kind of aluminum alloy die casting cooling fin three stage structures.
Background technique
Currently, the pattern draft structure of aluminum alloy die casting cooling fin is all one section of draft to bottom, gradient is 1.2~
1.5 ° (as shown in Figure 1), the disadvantage is that pack alloy raw material are relatively more, product weight, higher cost, traditional aluminium alloy pressure
When casting cooling fin one-part form structure pattern draft is 1.2 °, cooling fin has biggish sectional area, thus cause raw material more,
The problems such as product aggravates.
Utility model content
The utility model is intended to provide a kind of aluminum alloy die casting cooling fin three stage structure, solves aluminium in the prior art and closes
Golden die casting cooling fin needs more aluminium alloy stock, product weight, problem at high cost.
The utility model provides a kind of aluminum alloy die casting cooling fin three stage structure, including what is set gradually from top to bottom
First fin portions, the second fin portions and third fin portions, the first fin portions, the second fin portions, third cooling fin
The vertical cross-section in portion is isosceles trapezoid, and the bottom surface of the first fin portions is connect with the upper surface of the second fin portions, and second
The bottom surface of fin portions is connect with the upper surface of third fin portions, and the angle of the first fin portions two sides is dissipated less than second
The angle of backing portion two sides.
Further, the angle of the second fin portions two sides is less than the angle of third fin portions two sides.
Further, the section of the first fin portions be upper bottom width 1.4mm, lower bottom width 1.85mm, high 20mm isosceles ladder
Shape, the section of the second fin portions are the isosceles trapezoid of upper bottom width 1.85mm, lower bottom width 2.96mm, high 30mm, third cooling fin
The section in portion is upper bottom width 2.96mm, lower bottom width 4.37mm, the isosceles trapezoid of high 40mm.
Using aluminum alloy die casting cooling fin three stage structure provided by the utility model, with traditional aluminum alloy die casting
Cooling fin one-part form structure, which is compared, has lesser sectional area, can effectively reduce raw material of aluminum alloy, and reduces weight
Amount, convenient transportation are suitble to large-scale promotion application.
Detailed description of the invention
Attached drawing described herein is used to provide a further understanding of the present invention, and is constituted part of this application,
The exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the improper of the utility model

Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in detail.
Referring to Fig. 2, the utility model embodiment provides a kind of aluminum alloy die casting cooling fin three stage structure, including from upper
The first fin portions 1, the second fin portions 2 and the third fin portions 3 set gradually under, the first fin portions 1, second dissipate
Backing portion 2, third fin portions 3 vertical cross-section be isosceles trapezoid, the bottom surface and the second cooling fin of the first fin portions 1
The upper surface in portion 2 connects, and the bottom surface of the second fin portions 2 is connect with the upper surface of third fin portions 3, the first fin portions
Angle of the angle of 1 two sides less than 2 two sides of the second fin portions.
As a kind of more preferably embodiment, the angle of 2 two sides of the second fin portions is less than 3 two sides of third fin portions
The angle in face.
Wherein, the lower bottom width of the first fin portions 1 is identical with the upper bottom width of the second fin portions 2, the second fin portions 2
Lower bottom width is identical as the upper bottom width of third fin portions 3.
As a kind of specific embodiment of the utility model, the sections of the first fin portions 1 be upper bottom width 1.4mm, under
The isosceles trapezoid of bottom width 1.85mm, high 20mm, the section of the second fin portions 2 are upper bottom width 1.85mm, lower bottom width 2.96mm, height
The isosceles trapezoid of 30mm, the section of third fin portions 3 are upper bottom width 2.96mm, lower bottom width 4.37mm, the isosceles ladder of high 40mm
Shape.
By taking specific embodiment as an example, sectional area calculates as follows the aluminum alloy die casting cooling fin three stage structure:
The sectional area of first fin portions 1 are as follows: (1.40+1.85) × 20 ÷ 2=32.5mm2
The sectional area of second fin portions 2 are as follows: (1.85+2.69) × 30 ÷ 2=68.1mm2
The sectional area of third fin portions 3 are as follows: (2.69+4.37) × 40 ÷ 2=141.2mm2
The total sectional area of the aluminum alloy die casting cooling fin three stage structure are as follows:
32.5+68.1+141.2=241.8mm2
The draft of the first fin portions 1 in the aluminum alloy die casting cooling fin three stage structure positioned at bottom is about
1.2 °, the drafting angle positioned at second fin portions 2 at middle part is about 0.8 °, and superposed third fin portions 3 are pulled out
Modular angle degree is about 0.65 °.
Traditional aluminum alloy die casting cooling fin one-part form structure, one section draft to bottom, drafting angle are 1.2 °,
Referring to Fig.1, which is the isosceles trapezoid of upper bottom width 1.40mm, lower bottom width 5.17mm, high 90mm, calculates its sectional area are as follows:
(1.40+5.17) × 90 ÷ 2=295.65mm2
From with calculated result, it is apparent that using aluminum alloy die casting cooling fin provided by the embodiment of the utility model
Three stage structure, comparing with traditional aluminum alloy die casting cooling fin one-part form structure has lesser sectional area, sectional area
Lacked as many as 18%, can effectively reduce raw material of aluminum alloy, and reduce weight, convenient transportation is suitble to extensive
It promotes and applies.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
