Production Introduction
Skived Heat Sink is one kind of heat sink by processes of slicing the fins up a aluminum or pure cooper block on one of its surface with precision machining and then fold the fins vertically, similar to page turning.
Specification for Skived Heatsink
| Material |
AL6061, 6063, 1050, 1050, & Pure Copper |
| Thickness of the machining material |
10~40mm |
| Width of fins |
< 350mm |
| Height of fins |
10~70mm |
| Thickness of fins |
> 0.4mm |
| Distance between fins |
1~5mm |
Application:
Widely applied in the devices generating high density of heat, such as semiconductor refrigeration, servers, communication equipment, laser devices, projectors, industrial control equipment, etc.
Advantages of Skived Heat Sink:
| 1. Favorable heat-conducting property |
The fins and the base are made from the same extruded block, achieving 100% heat contact. |
| 2. Adjustable height & thickness of fins and distance between fins |
Can be achieved by adjust the tool of the lathe. No need to making new tooling. |
| 3. Large heat exchange area |
50% more than the Alu. Extruded Heat Sink with the same size and weight |
| 4. Same material for the whole part |
Easily treated with different surface treatment, such as anodizing , passivation, etc. |
| 5. Efficient and reliable heat dispersion |
Can keep the high-efficiency cooling without risk of failure |
