extruded heat sink
1, features: pinch heat sink is also called riveted heat sink, the use of stamping equipment to press the blade together or the blade is pressed into the base of the groove.
2. Advantages break through the aluminum extrusion industry in the heat sink blade height and thickness multiple or complex structure of the blade limitations, can produce higher density radiator, can choose different blade material, and the production efficiency of the product is high, the product cost is low
3. The shortcomings
3.1 Withhold heat sink will have a certain gap in the stamping riveting, which will affect the heat dissipation effect.
3.2 Stamping and riveting die costs will be incurred, so there is a certain amount of demand limit, small amount of products are not suitable for this process.
At present, the largest punch of our company is 250T, which can produce product size L800*W800* H150mm
