Description

A kind of radiating subassembly

Technical field

The utility model is related to technical field of heat dissipation, and in particular to a kind of radiating subassembly.

Background technology

The main moulding process of radiator has at present：

1, aluminium extrusion (Extruded) technology：Aluminium, as the highest metal of amount in the earth's crust, at low cost is that it is main special Point, and since aluminium extrusion technology content and equipment cost are relatively low, so aluminium material is applied very early in radiator market. Technically simple the saying of aluminium extruded is exactly that aluminium ingot is heated at high temperature to about 520~540 DEG C, allows molten aluminum to flow through tool under high pressure fluted Extrusion die has, and makes cooling fin germule, is so cut again to cooling fin germule, just to have made us after the processing such as profile groove common The cooling fin arrived.General common aluminium extruded type material is AA6063, with good thermal conductivity rate (about 160~180W/m.K) with Processability is most commonly used processing procedure.But due to being limited the thickness and length ratio of radiating fin by material itself No more than 1：18, so being difficult to improve heat dissipation area, therefore aluminium extruded cooling fin heat dissipation effect is poor in a limited space, very The competent high-frequency CPU increasingly soaring now of hardly possible.

2, aluminium die-casting die cooling fin:After its processing procedure system melts aluminium ingot at liquid, it is packed into metal pattern, utilizes die casting Machine rheo-die-casting is molded, and cooling fin is made, fin can be made to a variety of three-dimensional shapes using drape process, cooling fin can be on demand It is made complicated shape, fan and airflow direction can also be coordinated to make the cooling fin with water conservancy diversion effect, and can be made thin and close Fin increases heat dissipation area, is widely adopted because simple for process.General common die-casting die aluminium alloy is ADC12, due to Die cast is good, and suitable for doing light casting, but because pyroconductivity is poor (about 96W/m.K), the country is mostly with AA1070 now Aluminium material comes as die-casting material, and pyroconductivity is up to 200W/m.K or so, has good heat dissipation effect, but with AA1070 Aluminium material carrys out die casting there is some as follows.

The problem：

(1) surface flow liner and oxidizing slag are excessive when die casting, can reduce heat transfer effects.

(2) inside micro hole is higher when cooling, and substantive pyroconductivity reduces (K<200W/m.K).

(3) mold is erodible, causes the service life shorter.

(4) insufficient formability is not suitable for light casting.

(5) the material is soft, is easy modification.

As power is constantly promoted, in order to reach preferable heat dissipation effect, using the aluminium radiator of die-casting process production Volume continues to increase, and many problems, and the effective radiating surface of cooling fin that this technique makes are brought to the installation of radiator Product is limited.
