Cold Plate With Machined Flow Turbulators

      Disclosed is a process for high conductive heat transfer cold
plate for increased cooling of circuit module.

      A cold plate is a thin box-shaped metal structure with internal
fins 1 arranged in a pattern to define channels 2 that carry chilled
water.  Some cold plates are formed by joining upper 3 and lower 4
parts that have a symmetrical pattern of fins that form complementary
channels that are outwardly open before the parts are joined.  The
two parts are assembled with the outermost edges of the fins of one
part touching the corresponding edges of the other part. The channels
are made as narrow as required to provide enough fins for heat
transfer, but the channels are made as wide as possible in order to
simplify the manufacturing operations associated with forming the
channels.  The channels are machined by end mill.

      In this cold plate, the lower channels 4 are made the same as
before.  The top channels 3 are machined by circular saw so that a
circular wall 5 is formed in the middle of the flow channels.  This
machined flow turbulator provides a high convective heat transfer
rate.
