Abstract

As the TCM cooling advances to higher performance cooling requirements, the cold plate, which provides the external cooling, is required to be transformed from the separate type into the integral type. Disclosed is one of the integral cold plate designs extending from the current technology to higher performance TCM cooling.

Integral Dual Impingement Module

      As the TCM cooling advances to higher performance cooling
requirements, the cold plate, which provides the external cooling, is
required to be transformed from the separate type into the integral
type.  Disclosed is one of the integral cold plate designs extending
from the current technology to higher performance TCM cooling.

      As shown in the design configuration, this invention discloses
a design with spring-loaded pistons housed in the hat cavities with
narrow oil gaps.  On the hat side there are staggered cavities filled
with nozzles which provide jet impingement cooling on the cavities'
surfaces.  In addition, each nozzle wall and the cavity inner space
forms a narrow concentric channel which provides a microchannel
cooling for enhanced performance.

      As shown, the design can be comfortably extended to higher
performance by drilling holes in the piston or allowing similar jet
impingement and narrow channel cooling inside the pistons.
Prototypes of this design were built and tested to demonstrate the
concept.  Fluid flow convection model and finite element conduction
model were also made to verify this design.
