I'm trying to design an small but effective heatsink (DIY type), the design that I came up with so far is a 4x4x9cm aluminum square tube with a 12V fan under it blowing up:
poor designing skill...
The size of the heatsink is choosen based on the box space limit and I only have access to one side of the heatsink to install the regulators. I want to install 4 inefficient linear regulators on it, which in worst case will waste 20 watts of power in total.
- Does vertical heatsinks have any advantages over horizontal heatsinks?
- How can I calculate the cooling capability of this heatsink?
- That regulator which is going to dissipate more heat, should be at the bottom side of heatsink or top?
- Where should I install the temperature sensor to monitor the temperature and change the fan speed?
