Some circuit modules have semiconductor chips mounted in an array on a thin flat substrate that for purposes of terminology is arbitrarily positioned in a horizontal plane with the chips on the upper surface. Apparatus called a hat overlies the chips and cooperates with the substrate to form an enclosure for the chips. Metal components are spring-loaded to contact the upper surface of the chip and conduct heat from the chips to the hat. The hat is cooled with chilled water.
