Cold Plate With Folded Fin Sandwiched Between Two Parts With Fins for Increased Cooling of Circuit Module

      Disclosed is a process for high heat transfer fin density
assembly of a 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
fins and channels.

      In this cold plate, the channels are made the same width as
before in order to maintain the simplified manufacturing operations.
Before the two parts are assembled, a third part 5 with folded thin
fin structure is placed between the two parts.  The three parts are
assembled with the outermost edges of the fins of the two parts
touching upper and lower surfaces of the thin fin part. Thus, the
number of fins is greatly increased without reducing the channel
width from a manufacturing standpoint.
