Traditional metal shell radiator is to adopt metal shell directly as heat radiation purposes, but metal has high conductivity, if directly contacted with human body, is easy to occur the injury of getting an electric shock.In addition, density metal is higher, easily, after being assembled into whole lamp, causes LED lamp weight to lay particular stress on.
Developed afterwards the scheme of the in-built metal heat sink of plastics, this scheme is that metal heat sink is fixed on to the plastic housing inside with louvre, but being this scheme, the shortcoming of this scheme produces, assembles complexity, too small louvre can not fully contact with the cold air outside plastic housing metal heat sink, causes the effect of metal heat sink to be had a greatly reduced quality.
Therefore the follow-up scheme that further develops out heat-conducting plastic alclad cup radiator, this scheme is by the abundant combination of feature light heat-conducting plastic quality, that insulating properties is high, design freedom convenient and metal cup thermal conductivity is high.Roughly, this scheme is to utilize the technique of metalwork embedding and injection molding, and the die cavity of aluminium cup being put into mould is pre-buried, then the plastics of hot melt are injected to die cavity, and cooling rear plastics and aluminium cup combine.
And the scheme of this kind of heat-conducting plastic alclad cup radiator, on actual production is made, often have various geneogenous problems, for example, in injection molding process, molten plastic is injected in cool die cavity, in the process that the plastics of viscous state solidify in moulding, due to plastics poor thermal conductivity or mold temperature higher, product can be because of cooling generation volume contraction in various degree, makes the surperficial raw material at wall thickness place be drawn into, and there is dent mark at finished surface, cause the phenomenon of shrinking.
For improving the problem of shrinking, industry has proposed some solutions, for example:
Improve injection molding process, this scheme is to improve injection pressure and continue pressurize to mould after injection moulding, and gives and enough cool times, to prevent the phenomenon of shrinking.But the shortcoming of this kind of scheme is that injection time is long, causes production efficiency low.
Improve mould, this scheme is that reasonable mold cooling water passage distributes, and prevents the phenomenon of shrinking, but this kind of scheme effect not obvious.
Improve product structure, this scheme is to make even thickness by changing product structure design, avoids product thickness inequality, and thick meat part divides and is difficult to coolingly, occur shrink in various degree, but inevitable product wall unevenness appears in product design sometimes.
