A system configured for cooling a thermally insulated galley cart, the system comprising: a skin heat exchanger configured to transfer heat to an aircraft skin by contact so that a working fluid coolant is conditioned during flight at high altitudes where cold external temperatures outside the aircraft skin are employed by the skin heat exchanger as a cold sink; and a cooling system in communication with the skin heat exchanger, wherein the cooling system is configured to be removably coupled with the thermally insulated galley cart, IGC, wherein the cooling system further comprises: a closed coolant loop comprising a coolant pump, the skin heat exchanger, and at least one coolant-to-air heat exchanger, and employing a non-freezing coolant as the working fluid coolant; and at least one semi-closed air loop (14, 16) configured to be removably coupled with the IGC, wherein the at least one semi-closed air loop (14, 16) further comprises: a plurality of blowers (46a, 46b, 46c) configured to draw cabin air through the at least one coolant-to-air heat exchanger and to deliver cooled air to the IGC; a supply duct having a supply opening configured to be removably contacted by an inlet valve in the IGC, the inlet valve automatically operable to open upon engagement of the IGC with the at least one semi-closed air loop (14, 16) to introduce cooled air from the supply duct to the IGC; and an exhaust duct having an exhaust opening configured to be removably contacted by an exhaust valve in the IGC, the exhaust valve automatically operable to open upon engagement of the IGC with the at least one semi-closed air loop (14, 16) to exhaust the cooled air from the IGC, wherein a proximity detector associated with the IGC is operable to determine a presence of the associated IGC docked at one of the plurality of blowers (46a, 46b, 46c), each of the blowers (46a, 46b, 46c) configured to be activated in response to an output of the proximity detector when the associated IGC is placed in a location adjacent the one of the plurality of blowers (46a, 46b, 46c) in that location. a skin heat exchanger configured to transfer heat to an aircraft skin by contact so that a working fluid coolant is conditioned during flight at high altitudes where cold external temperatures outside the aircraft skin are employed by the skin heat exchanger as a cold sink; and a cooling system in communication with the skin heat exchanger, wherein the cooling system is configured to be removably coupled with the thermally insulated galley cart, IGC, a closed coolant loop comprising a coolant pump, the skin heat exchanger, and at least one coolant-to-air heat exchanger, and employing a non-freezing coolant as the working fluid coolant; and at least one semi-closed air loop (14, 16) configured to be removably coupled with the IGC, wherein the at least one semi-closed air loop (14, 16) further comprises: a plurality of blowers (46a, 46b, 46c) configured to draw cabin air through the at least one coolant-to-air heat exchanger and to deliver cooled air to the IGC; a supply duct having a supply opening configured to be removably contacted by an inlet valve in the IGC, the inlet valve automatically operable to open upon engagement of the IGC with the at least one semi-closed air loop (14, 16) to introduce cooled air from the supply duct to the IGC; and an exhaust duct having an exhaust opening configured to be removably contacted by an exhaust valve in the IGC, the exhaust valve automatically operable to open upon engagement of the IGC with the at least one semi-closed air loop (14, 16) to exhaust the cooled air from the IGC, a plurality of blowers (46a, 46b, 46c) configured to draw cabin air through the at least one coolant-to-air heat exchanger and to deliver cooled air to the IGC; a supply duct having a supply opening configured to be removably contacted by an inlet valve in the IGC, the inlet valve automatically operable to open upon engagement of the IGC with the at least one semi-closed air loop (14, 16) to introduce cooled air from the supply duct to the IGC; and an exhaust duct having an exhaust opening configured to be removably contacted by an exhaust valve in the IGC, the exhaust valve automatically operable to open upon engagement of the IGC with the at least one semi-closed air loop (14, 16) to exhaust the cooled air from the IGC, wherein a proximity detector associated with the IGC is operable to determine a presence of the associated IGC docked at one of the plurality of blowers (46a, 46b, 46c), each of the blowers (46a, 46b, 46c) configured to be activated in response to an output of the proximity detector when the associated IGC is placed in a location adjacent the one of the plurality of blowers (46a, 46b, 46c) in that location.
