Abstract
An improved apparatus for regulating air flow between a cooling unit and a compartment in a refrigeration system includes a first baffle element having an array of first air passages, and a second baffle element having an array of second air passages. The first baffle element and the second baffle element are slidingly engaged and are slidingly positionable with respect to each other. The first air passages and the second air passages cooperate to pass air through the apparatus when the first baffle element and the second baffle element are in a first position, and the first air passages and the second air passages cooperate to substantially block air from passing through the apparatus when the first baffle element and the second baffle element are in a second position. The apparatus further includes an actuator coupled with the first baffle element and the second baffle element for slidingly positioning the baffle elements, the actuator having an actuated state and an idle state. The apparatus further includes a standoff structure for establishing a predetermined separation distance between the first baffle element and the second baffle element proximal to the standoff structure. …
