I need a heat sink like this one, please help?
I have been looking to find a long heat sink like this one: http://www.anglia-live.com/products/kw/LAM-4-150-05-V/774353001_HEATSINK-FAN-150MM-5VDC but I can't find one that is cheaper or similar (Other than other models of this). I basically want to make a thin air conditioner with about 18 peltier units. I want one of those heat sinks on the hot side. I then want to do the same thing on the cold side or I want to use a bunch of mini 40x40mm fans on each cold side of the peltier units. Please let me know if you know any similar heat sink designs or if there is a name for this kind of design.
Also, if there are no similar heat sinks, could I just go to Home Depot and buy a hollow aluminum square pipe and add a mini PC fan instead of this? I would assume it wouldn't be as effective because of the less surface area, but, it would be cheaper I think.
