    Abstract: A pre-formed insert with stable dimensions for mechanical insertion into a hollow member and that reduces the Nusselt number and convection across the hollow member. The insert may be formed of a low heat conducting material like PVC and have extensions and internal voids that impede convection in the hollow and conduction through the insert. The inserts may be used in heads and sills of aluminum windows, doors and frames. In one embodiment, an insert is received in an open hollow and may cooperate with an insert in a frame hollow to decrease convection at the head end of a sliding window or door. An insert may be placed within the hollow of a window or door beside a roller assembly.

    Abstract: Systems for cooling a heat-treated metallic part include a plurality of atomization nozzles disposed on a stage and radially disposed about the part to be cooled; and a fluid in fluid communication with the atomization nozzles. The fluid may gas, liquid, or a combination thereof, e.g., water and gas. During use, the atomization nozzles are generally configured to rapidly cool the thicker sections of the part relative to the thinner section since the thicker sections are generally slower to cool. In some embodiments, the stage can be configured to rotate about the part during cooling.
