Will a patchbay act as a heat sink in a rack?

Will a patchbay act as a heat sink in a rack?

I am a little short of rack space and I was wondering if I could sandwich heat producing units between patchbay units.

Specifically a Metric Halo ULN8 between an ADC 2U patchbay (30cm deep) and a 1U patchbay (12cm deep) without any space between in a upward angled rack.

Or is it all about air flow?

Couldn't say about the airflow. But you may want to consider what you're mounting your patchbay on top of, because the dangling cables will get in the way.

I would say it's all about airflow. Actual heat sinks are very tightly coupled to whatever they are sinking.

Yep both good points. Given the uln8 a 1/3 space either side and put patchbays together beneath.

Putting in a patch bay or other non-heat-producing unit would be better than a heat producing one obviously -- and more than a bit depends on the design of the units above and below -- but, for sure, air flow would be better. Don't forget that heat sinks work by coupling to the heat-producing object and then, typically, using air fins to dissipate the transferred heat into the air.

Most patchbay are not full depth rack units, and if this is the case they will not block the vents on most rack gear. With that said, having patch cables dangling in front of the controls on your rack gear is reason enough to not organize your rack this way.

Just buy another rack and be happy your only problem is “I have too much gear.”

Ah, but when the wife sees a new rack appear, with just one unit in it, her mind is going to race ahead to the inevitable conclusion that it's only a matter of time...

This is why it's much kinder to the spouse to just lease a building and go whole hog. The kids can pay for their own university...


It's the gearslut slippery slope.

A guy's wondering if he can get away with putting a patch bay between two pieces of rack gear and the next thing you know, he's taking out a second mortgage...

Just like when the husband sees a book of baby names appear.

I agree that a patch bay won't work as a heat sink, since it's not coupled to the heat-producing units (and even if it were attached to their outer casings, it wouldn't do much... it'd need to be coupled to the actual components within that generate heat).

Just tell your wife you are actually saving money by buying another rack, because that way you will not accidentally burn down your studio/house by trying to use a patchbay as a heat sink. Doh!

My ULN8 has sat under my Redco patchbay with a power amp beneath it for 4 years. Cabling's not an issue as most of the ULN8 functions can be controlled via software and my bay is 75% normaled and I at most have 6 or 8 cables hanging from it. I find the DI and HP jacks easy to find.

I live on the wild side.

ETA - the Redco is pretty short.

no way i could see it acting as a heat sink bout would offer some air space. if the ait does not move not sure what could it would be?
and if the air did move if it done what i assume you want, there is no way in HE doule hocky sticks i would want the dangling cables over some othe unit i want in my rack. if it was gear i. did not care about it would be in the rack and there would be no issue anyways.

even as the 500 format slutz i am i can stand gear such as mixer type thingys that rely on cabe hanging out the front panel. thats why i've always said iff you want a mixer design it for it own bucket not the 500 frame.
