1. A temperature controlled case, comprising:
a housing that defines a temperature controlled space, the housing including a duct that receives circulated air, the duct having a lower wall oriented at a first angle from horizontal;
a support structure coupled to the lower wall of the housing, the support structure having a height that varies longitudinally and a length;
a heat exchanger coupled to the housing via the support structure, the heat exchanger coupled to the support structure along the length of the support structure, the heat exchanger disposed within the duct at a second angle from the lower wall and at a third angle from horizontal that is greater than the first angle, the heat exchanger including a primary intake face, a secondary intake face adjacent the primary intake face, a primary outlet face positioned on an opposite side of the heat exchanger relative to the primary intake face, and a secondary outlet face positioned adjacent the primary outlet face, where the height of the support structure angles each of the primary intake face, the secondary intake face, the primary outlet face, and the secondary outlet face at a non-perpendicular angle relative to an air flow direction in the duct immediately upstream of the heat exchanger, where the primary intake face is fully open to pass circulated air that is cooled by the heat exchanger before being discharged via at least one of the primary and secondary outlet faces, and the secondary intake face is at least partially open to pass circulated air that is cooled by the heat exchanger before being discharged via at least one of the primary or secondary outlet faces; and
an air mover disposed downstream of the heat exchanger in the air flow direction, the air mover mounted in a panel positioned angularly within the duct to induce an airflow through the primary intake face and the heat exchanger, to the primary outlet face, and to the temperature controlled space, the panel configured to restrict the airflow from the primary outlet face through the air mover.
