What is it ?

[kurtak]

Ok I just came across this in a bucket of miscellaneous scrap (e-scrap) it appears to be some kind of fluid cooling type heat sink & appears to be gold plated (acid test)

As I pulled it from a bucket of miscellaneous scrap I have no idea where or what it came from & there are no part numbers - it does have KOOLANCE etched/stamped into the plastic housing

This is the only picture I had easy access to. Your heatsink is a little different design but much like the water cooling blocks attached to the DLP chips on the light engine of one of our cinema projectors. This one is held in place by the chrome metal strap which straddles it. There is a dimple and pin in the middle so the heatsink self-centers on the strap and it can't slide around. Older models just used copper blocks that the coolant was circulated through. There are 3 of these on the light engine, one for each DLP chip and the boards they're on are mounted in sort of a flat-bottomed "V" arrangement. This is the red formatter board, the edge of the green formatter board is visible on the right, and the blue formatter board is hidden on the far side. There is a glass prism sitting in between them, the xenon lamp light would be coming up from optics below, and the inner end of the lens would be placed between the red and blue boards and projecting toward the left as it's sitting here.
