Heatsink Question

[myleftear]

Hello...

I am bitten by a non-standard idea, but...
Does anyone ( @Gianluca ?) know wether the Modushop Heatsink 200 X 40 H 210 mm (5U , here ) really has a temperature coefficient of 0,28 C°/W ?
I'm not sure because it's part of the 5U 400 which has 2 Heatsinks per side... Not sure because the complete chassis does not declare it's TC ...
thankyougrazie!

Hi there!

Unfortunately, we don't have the thermal coefficient (TC) for the entire chassis because our supplier only provides values for individual heatsinks and not for both of them combined.

Should you have other questions feel free to ask and I'll be happy to answer.

Hi
The datas are given per heatsink and i would trust them
For 400mm you just have 2 heatsinks per side,so an rough equivalent of 0.14c/w if you spread your transistors to use both heatsink. See how many transistor you will put per heatsink, it makes it easier ( at leat for me)
Of course thermal dissipation in front panel or else is not taken into account

Cristal-clear, Gianluca, thank you!
I don’t doubt the information as being accurate, but needed clarification!

Thanks to lolo6990, Gianluca now has the answer he was looking for 😀

here's what I'm after… (I may have to up it to 250 mm wide!?)
