Stitched fin heatsink
Water cooler
Stitched fin technique is a conventional high power heat sink manufacturing technique. Conventionally, this process is carried out by press-fit riveted fins. However, this usually leads to potential thermal risks such as matching clearance, loose fins, etc. To resolve this problem, Winshare Thermal launched several bonding techniques via our own technical innovations and these include highly conductive thermal epoxy bonding, welding, and soldering so as to greatly enhance the reliability and stability of cooling and avoid any potential risk.
The features of stitched fin heat sinks include more fins per inch, smaller fin gap, and flexible profile height and width so that they are suitable for different sizes of application space. This type of heat sinks occupies a smaller volume and they are lightweight and therefore this technique is an ideal selection for cooling high power devices.
Prepare aluminum/copper baseplate and cooling fins according to the design drawings and create slots on the baseplate
Bond the cooling fins to the baseplate by epoxy so as to join them into an assembly
Carry out machining and surface treatment on the baseplate and cooling fins so as to form the stitched fin heat sink
