water heat sink

cquent

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

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.

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?

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?
