I have been attempting to identify some early CPU coolers, At first I was led to believe 
they were off of an IBM system, I have not found any IBMers that could identify them. 

I am now thinking they may have been fabricated for any water chilled system, 
they may have been a retrofit for an air cooled system in a water chiller enviroment.

>From the size of the feed lines, this was a low pressure high volume chiller, and there 
were between 30 and 40 of these hanging on the system doors.

Here is a link, if anyone recognize them, I am sure Lew (the owner) would love to know as 
would several others who are equally baffled.
