Cold plates

Hello,
I need cold plates for medical instruments.
I have gone through many sites like riversidemachine
But i am bit confused ....so please tell me if this site is good for cold plates or suggest me something new.

im not sure how many people here deal with medical instruments, or large bits of raw materials. sorry.

The purpose of a cold plate is to spread the heat output from a concentrated zone(i.e. cpu die), otherwise known as a heatspreader. It is called a cold plate when it sits on the cold side of a chiller. I wouldn't go through a machine shop unless you need some special shape, design or precise measurements. I'd just get a flat bar of copper from onlinemetals.com or mcmaster.com, and cut it..
