i am looking for a aluminum box with heatsink and a flanged cover for mounting. cast is what i suspect it will be made of. relatively small in size 3x3x1 or 4x4x1 (plus height of heatsink, etc). it's for a automotive application/circuit i am working on. i've seen some automotive electronics that use this, but i suspect they might have had it custom made, i'm looking for off the shelf item. the heatsink is some fins top side and the bottom cover is flanged for mounting. i will be potting my pcb.

or, an extrusion would work if one side had fins and allowed for a covers, etc.

anyone seen a box or extrusion like this? i wish to avoid mounting a seperate heatsink to a box, etc.

 

These extruded boxes are all over ebay: http://cgi.ebay.com/Brand-New-Alumi...ms=65:1|66:2|39:1|240:1318|301:0|293:2|294:50

There is also a cast box of those dimensions but is about 2" high. Search: project boxes.

i need fins, something like this

 

It is easy to attach a heat sink to the box like this. The PCB is attached to the heatsink and the box lid cut out to accommodate that.

Also, potting generally makes heat dissipation worse.

having to "cut" is what i want to avoid. potting makes production for me so much easier. its not a one-off item, i will be making many, etc. my main objective with my stuff is to simplify.


i use this Hammond case for lots of things (1455C801BK). it would work for me if i could find a heatsink that would fit as one of the end panels. anyone know if such a heatsink exists? i had emailed Hammond asking about heatsinks would fit but i got no reply, my guess is they dont know.
