water heat sink

16 Mar 2022

Hello,

I want to size a water heat sink to dissipate the power of 16 MOSFET transistors of 300W each.

I would like to do this study to compare it to a finned radiator with fan.

However, I don't know how to go about it.
Can you help me?

Thank you

Hello,

These are 16 MOSFET transistors of the IXTN22N100L type.

The 16 transistors are in a drawer of an ATE test rack. it is currently used with a fin and fan disabled. but I would like to find a way to replace the fan and serve fin with a water thermal plate. For the closed circuit with water this is not a problem there are cold groups. What interests me is how to determine by calculation the water thermal plate. What are the thermal parameters to consider?

Thanks Doug.

I have also heard that there are heat sink solutions with Peltier modules or even heat pipes.

Is it true that the Peltier module has low efficiency?
Is a heat pipe plate possible in an ATE rack drawer?

Yes Peltier coolers are very inefficient.

Heat pipes transport heat from one place to another, but you still have to have a way to cool off the heat pipe.
