Roll-bond component forming cart bay walls with liquid circulation and a high efficiency micro-chiller heat sink

An apparatus comprising:

• an exterior housing formed to be integrated in a galley bay, wherein the exterior housing is configured with a set of elements comprising:
• an interior housing having a rear wall, a first side wall, a second side wall, a top, and a bottom;
• a roll bond evaporator component;
• a micro-chiller unit configured within the rear wall of the interior housing, the micro-chiller unit comprising:
• a ring-shaped liquid chiller disposed within the rear wall,
• a heat sink configured to repel warmer air, and
• thermo-electric elements disposed between the ring-shaped liquid chiller and the heat sink, the thermo-electric elements configured to chill the liquid;
• and
• a pump disposed within the rear wall and configured to circulate the liquid through the roll bond evaporator component;
• wherein the interior housing is chilled by liquid circulated between the micro-chiller unit mounted on a side of the interior housing and the roll bond evaporator component that forms at least one of the first side wall or the second side wall of the interior housing;
• wherein an input of the roll bond evaporator component is attached to the micro-chiller unit configured to receive liquid chilled by the micro-chiller unit;
• wherein an output of the roll bond evaporator component is attached to the micro-chiller unit to send liquid to remove heat intercepted from the at least side of the interior housing formed by the roll bond evaporator component.
