I need 2 large heat sinks for my stereo Class AB amplifier build. Ideally, width = 350-400 mm, length = 150-200 mm, fin height = 50+ mm.
So far I have only found Conrad Heatsinks' MF35-151.5, which has a C/W of 0.21 (0.25 corrected). I would like a heat sink with less than 0.25 C/W.
Ideally I will use the heat sinks as the sides of the chassis for the build - that is, no side panels, just heat sinks.
All other heat sinks I have found (on stores like Mouser, Digikey, RS NZ) have been too small, or way too expensive (ABL Components 177AB2000B is 155 USD for one in NZ - this is probably more than I'd spent to get 2x MF35-151.5 SHIPPED).
What heat sinks / heat sink companies are out there that could be suitable?
If there are no other options I will probably go for the MF35-151.5.
