go look inside of an old computer. there should be one on the processor.
i'm also a little confused now.. your title says a heatsink for an aixiz and your main post says you need a heat sink for a tec.
michael.
trying to get something in this form factor: LASER module GREEN 50mW Sales, Buy LASER module GREEN 50mW Products from alibaba.comIn that case a CPU heatsink should be perfect.. the bigger the better.
Did you happen to notice the link I posted in post #4? That's pretty much precisely the same as what is in that picture.. better actually since it gives more surface area for dissipation.
^Well stated Michael!
Those z-bolt heatsinks are about 3.5" square by 1.5" deep..
Maybe there's a misunderstanding here about how the TEC functions.. Ideally you'd want the diode in a heatsink (the mount you have will do perfectly), which you then place on the cold side of the TEC. Then below the hot side of the TEC you need either a thick metal baseplate or another heatsink to dissipate the warmth from the hot side of the TEC, which is why I recommended the CPU sink. So you'll end up with a sandwich with a heatsink on top and another on the bottom.. It will be pretty difficult for you to have everything contained in the form factor you linked to.
How cool are you trying to keep the diode? You should only need minimal TEC current to keep the diode at a safe temperature.. it sounds to me like you might be driving the TEC too hard, causing it to produce more heat on the hot side.
