7. The cooling system of claim 6 , wherein the reservoir is installed in a fixed location that is remote from the vehicle; and
wherein the external coolant connection is configured to deliver the coolant from the reservoir to the flow system via the flow connection.
8. The cooling system of claim 1 , wherein external insulation of the mobile bulk tank extends over the heat exchanger.
9. The cooling system of claim 1 , wherein a plurality of flow ducts of the heat exchanger extend longitudinally along the mobile bulk tank.
10. A vehicle comprising:
a bulk tank with a top exterior wall;
a plurality of flow passages defined by corrugated sheeting secured to the top exterior wall of the bulk tank and at least partly defined by the top exterior wall so that a coolant flowing through the plurality of flow passages directly contacts the top exterior wall;
a pump configured to move the coolant through the plurality of flow passages to cool the bulk tank via the top exterior wall, wherein the corrugated sheeting is non-invasively secured to the top exterior wall of the bulk tank.
11. The vehicle of claim 10 , further comprising:
a reservoir for the coolant, the reservoir being supported by and configured to travel with the vehicle.
12. The vehicle of claim 11 , wherein the coolant includes vaporized liquid nitrogen.
13. The vehicle of claim 10 , wherein the corrugated sheeting is at least partly covered by an external insulation layer.
14. The vehicle of claim 10 , wherein the plurality of flow passages defined by channels of the corrugated sheeting extend longitudinally along the bulk tank.
15. The vehicle of claim 14 , wherein the plurality of flow passages are defined by multiple distinct corrugated sheeting arranged longitudinally along the bulk tank, wherein each distinct corrugated sheeting forms a heat exchanger to provide a plurality of heat exchangers along the bulk tank.
16. The vehicle of claim 10 , further comprising a flow connection in fluid communication with the pump;
wherein the flow connection is configured to receive an external coolant connection to provide the coolant to cool the bulk tank.
17. The vehicle of claim 15 , further comprising a main feed duct in communication with the pump, a feed manifold in communication with the main feed duct, and a plurality of distribution ducts extending from the feed manifold, wherein each of the plurality of heat exchangers is in direct communication with one of the plurality of distribution ducts so that the coolant is moved from the pump to the main feed duct, to the feed manifold, to the plurality of distribution ducts, to each of the plurality of heat exchangers to move the coolant through the plurality of flow passages.
18. The cooling system of claim 1 , wherein the heat exchanger includes a plurality of heat exchangers, and each heat exchanger of the plurality of heat exchangers includes the plurality of flow ducts.
19. The cooling system of claim 1 , wherein the each of the plurality of flow ducts is triangular in cross section.
20. A cooling system for a mobile bulk tank, the mobile bulk tank being configured to be transported by a vehicle, the cooling system comprising:
