Enclosure for β24

Postby mpa2 » April 18th, 2017, 12:52 am

Hi Ti, hi everybody!

I'm considering using bigger (deeper) 400 mm Dissipate enclosure for my beta24 build (AB). Hope to avoid some inconvenience due to limited space this way. However, it's heatsinks are divided in two 200 mm parts. Has anyone used this enclosure yet?
The b24 PCB's would probably fit the smaller heatsinks, but in this case I'll waste the half of the cooling capability. Or one could mount the PCB in the middle, so both heatsinks are used, and hopefully there would be enough space for the Sigma22s. Would the lack of thermal coupling be a problem in this situation?
Has anyone used this enclosure yet and could share his experience?

Michael

Are the two heatsinks on each side not thermally coupled to each other?

It's hard to tell, didn't find any information about it on the modushop website. Maybe someone has got his hands on it?

Well, according to this picture, they seem do be coupled... Ti, do you see any drawbacks using this enclosure?

Apply some thermal compouind at the mating surfaces of the two heatsinks. If possible, find a way to force the two pieces together (e.g., machine screws and nuts), so that the two may function as closely as one big heatsink as possible.

Answer from Modushop:

"Unfortunately we don't have a 400mm heatsink and the 2 200mm ones are not thermally coupled."

If you do as I said, then you'll be making them thermally coupled.

I have seen this photo on the B24 forum of a set of heat sinks that were 'thermo coupled'. I can't find which thread.

OK, it seems possible to use the 400 mm Dissipante, but with some workarounds.

Ti, and others, who used the 300 mm Dissipante - if you would build beta24 again, would you still use it or would you go for a deeper one? :)
