Aluminium alloy presses structure of cast carbon fin to design skill

Carbon fin is one kind gives machine in easy have a fever component comes loose hot device. Raise the area that generation heat passes between component and air through carbon fin, progress thereby medicinal powder hot efficiency, reduce component to be in run continuously the temperature in the process, those who make more the movement that does not last in disorder. Follow aluminium alloy to press cast to be in those who send the dynamical cell such as thought, electric machinery to go up to gain ground, more and more aluminium alloy that have carbon fin structure press cast extensive to rise, how the carbon fin structure on fairer design pressing cast, those who make coming loose the way that each respect such as the quality of hot function, cast, capital that make finds the most reasonable solution to become numerous cast to design an employee to ponder.

2 how to design aluminium alloy to press cast carbon fin
Aluminium alloy pressed the action of structure of cast carbon fin to decide, after product function often is in to finalize the design in products plan process optimize design stage. Below the situation that affecting early days design namely, the scheduled time and quantity after moving place to be united in wedlock changeably produces craft to choose the design of the fairest plan.

Author basis is engaged in pressing the experience that cast product develops for years. Summary gives a few relevant skill main component is the following two respects.

2.1 functions sex is designed
The function of carbon fin is to make have a fever the quantity of heat of the source diffuses the ala with larger area piece (blade) on, conduct through heat next transfer quantity of heat air, how to make the product comes loose is hot effect better?

Heat up those who conduct implementation to come loose formula of quantity of heat is as follows:
The come loosing that conducts implementation through heat quantity of heat [W] ＝ heats up conductivity [W/ (㎡ · ℃ ) ] × comes loose hot area [㎡] × and the temperature around are poor [℃ ] below the case with reach according to above formula inference pledges in material particular, medicinal powder hot area is larger, as bigger as around temperature difference. Medicinal powder thermal efficiency is taller.

Medicinal powder hot area: Usually the decision comes loose the sheet that heats up the two big factors of the area to be carbon fin is accumulated one-sidedly and carbon fin amount. Namely more sheet accumulates carbon fin one-sidedly bigger, medicinal powder hot area is larger.

As poor as the temperature around: Namely with airy difference in temperature, make more normal temperature air and carbon fin happening heat up move, with achieving the goal that drop in temperature. Sex of ascensive airy activity is the main measure that drop in temperature. In have peripheral (wait like fan) should ensure wind direction imports and exports is clear below the circumstance, without cut off. Should ensure below the circumstance that does not have peripheral, blade may appear unexpectedly, blade does not have crisscross, form expedite space to make as far as possible air convection.

Integrated above, conclude: Carbon fin amount is more; The area is larger; Leak effect jumps over beautiful, medicinal powder hot effect is better.

2.2 craft sex is designed
The purpose that craft sex designs is, adopt the design to pressing cast, in making product sequel volume is produced, produce efficiency is tall, percent defective is low, the process is grandiose little, achieve thereby efficient the target of effect low consumption.

The craft sex design of carbon fin should ensure the following:
1) hands-off whole assembles the distributinging position of carbon fin, not cover influence follow-up is assembled. Die-casting of give attention to two or morethings is filled model, carbon fin as far as possible little park is entered irrigate flow direction extreme.
2) the dimension of carbon fin, carbon fin ply is a product commonly the 2/3 with even large wall, the 10-20 that length is carbon fin ply times, differ somewhat according to actual item characteristics special appearance is exceptional. When too too long, thin lamina causes die-casting to produce easily, fill model difficult problem, the product is local owe casting, cold lie between etc be short of owe.

If the graph is shown 1 times, tag what place causes because of blade design to owe casting.

Graph 1 tag what place causes because of blade design to owe casting

3) carbon fin intensity, admittedly carbon fin does not rise commonly bearing action, but necessary intensity can reduce the because blade is curved,folds waste in production process. Blade root ministry needs to design ply of lamina of R= of R round horn. Can rise to increase blade strength, optimize die-casting to fill up wait for action.
