A heat transporting electrical assemblage retained in a retaining unit
transports heat between a heat sink and a thermal transport element in
fluid communications with the heat sink. The thermal transport element is
snugly arranged in a thermal gap between a coplanar thermal wall formed by
a wall of both the heat sink and the electrical assemblage. Thermal
transport element makes at least partial contact with a portion of the
coplanar thermal wall and with a portion of the retaining unit thereby
transporting heat from the hotter thermal wall to the cooler frame of the
retaining unit.
