Tuniq Propeller 120
In Figure 4, you can see the front side of the heatsink. On top of the base there is a small auxiliary heatsink. The main heatsink is horizontal and keeps a good distance to the base.
In Figure 5, you can see the heatsink from the side. According to the manufacturer, the "V" shape is inspired on the mighty aircraft carriers. Here you can see the four 8-mm heatpipes. Since there are two independent heatsinks, each tip of each heatpipe is connected to one heatsink. The fins are not plain, but with some rugosity in order to achieve better heat transfer.
From the top you can better see the disposition of the heatpipes.
