Heat sink for
electronic devices
Heat sink with high density and thin-walled fin made by brazing. It can cover heat condition which is difficult for classical extrusion or machining products.
High performance heat sink
- ・High performance heat sink by high density and thin-walled fin, which is difficult for classical extrusion material or machining. It is suitable for cooling high power processor for data sever, power supply, graphic, etc.
- ・Base plate and fins are brazed by SPP’s original technology,
and the brazed joint has good mechanical property.
- ・Custom-made design according to your requirement
- Suitable fin selection from various fin selection
- Available for wide range of size (Max. 1.3m by 1.8m plain)
About brazing sheet....
In case of Aluminum, filler metal is cladded onto and integrated with the brazing sheet. Filler metal has lower melting point than core material. By heating stacked core to temperature that do not melt core material but melts filler metal, the core is bonded.
*Possible fin pitch and thickness may be adjustable.
**Possible fin pitch and thickness may change depending on size of heat sink.
