High-surface area thermal protection modules for cargo containers and cargo containers including the same

A thermal protection module configured to operate in a low delta temperature environment, the thermal protection module comprising:

• a first heat transfer element having a first shell, the first shell having a constant profile along a length thereof, the first shell defining a closed first cavity that is filled with a medium, the first shell having a base, a cap, and two sidewalls that each extend between the base and the cap, the first heat transfer element defining a side edge of the thermal protection module;
• a second heat transfer element having a second shell, the second shell having a constant profile along a length thereof, the second shell defining a closed second cavity that is filled with a medium, the second shell having a base, a cap, and two sidewalls that each extend between the base and the cap, a first sidewall of the two sidewalls that is closer to the first heat transfer element meets the cap to form a divider, the divider positioned above the cap of the first shell when the base of the first shell and the base of the second shell are disposed within the same plane, the second heat transfer element adjacent to the first heat transfer element such that a gap is defined between the first heat transfer element and the second heat transfer element;
• a first bracket receiving a first end portion of the first heat transfer element and a first end portion of the second heat transfer element;
• and
• a second bracket spaced apart from the first bracket and receiving a second end portion of the first heat transfer element and a second end portion of the second heat transfer element such that the gap is defined between the first heat transfer element and the second heat transfer element along the length thereof.
