Disipating 60W of the hot side of the peltier cooler
(1/3) > >>
Saulius:
Hi fellow enginerds,

I haven't done much heat dissipation calculations. So I would like some advice.

I will be cooling some devices with a thermoelectric cooler, and I need to dissipate at least 60W on the hot side of the peltier element.
I am trying to decide on the most reasonable solution.
Distentions of the peatier element are 55x55mm.
I was thinking of using a heat sink, but not sure what size should I use and what size fan should I use.

If anyone has any advice, it will be greatly appreciated.
Thanks :)

That is about the right size and power budget for a standard CPU heatsink and fan.  I would first look if you can just use one of those off the shelf.

How close to ambient do you need to keep the hot side? I.e. If you're just temp stabilizing a laser or something, pretty much any desktop CPU cooler should suffice.
If your trying to stay as close to ambient as possible, something like a NH-D15 is about as good as you'll do in the consumer segment for a 1-piece solution. (I.e. not an All In One sealed water cooler)

Anandtech did proper thermal measurements with a 60W load (convenient for you )  https://www.anandtech.com/show/9415/top-tier-cpu-air-coolers-9way-roundup-review/12

6.5C above ambient at 60W, with thermal resistance coming in at 0.0944C/W for the 60-340W range.
SiliconWizard:
I would also consider a CPU cooler. Beware that the typical contact surface of a CPU cooler is smaller than 55x55mm, so that may leave a peripheral belt on the Peltier module excessively hot?

What are you going to do with this Peltier cooler?
Marco:
There's vapor chamber heat spreaders on Aliexpress nowadays, anyone ever tried them?
