An assembly for cooling a liquid inside a portable container. According to some implementations the portable container has a heat exchanger assembly disposed therein with the heat exchanger assembly including a coolant pre-cooling assembly. According to the same or other implementations a tortuous coolant fluid passage that runs through at least a portion of the heat exchanger assembly includes one or more constrictions for controlling the evaporation temperature of the coolant along the length of the passage.

1. A cooling apparatus comprising: a first longitudinal body having a first outer surface and a first inner surface, the first inner surface defining an internal chamber having first and second ends,a second longitudinal body disposed inside the first longitudinal body, the second longitudinal body having a second outer surface and a second inner surface, the second outer surface facing and being spaced-apart from the first inner surface of the first longitudinal body, the second inner surface defining an internal cavity having first and second ends, the first end being disposed in proximity to the first end of the internal chamber of the first longitudinal body, the second end being disposed in proximity to the second end of the internal chamber of the first longitudinal body,a tortuous conduit disposed between and along a length of the first and second longitudinal bodies, the tortuous conduit being defined in part by the inner surface of the first longitudinal body, the tortuous conduit having an outlet and an inlet that are respectively disposed in proximity to the first and second ends of the internal chamber of the first longitudinal body, the tortuous conduit outlet being in fluid communication with the internal cavity of the second longitudinal body, the tortuous conduit comprising a plurality of flow constrictors disposed within an intermediate portion thereof, the plurality of flow constrictors having different cross-sectional areas than one another. 2. A cooling apparatus according to claim 1, further comprising a coolant exhaust duct that exhausts to the atmosphere and that is in fluid communication with the second end of the internal cavity of the second longitudinal body. 3. A cooling apparatus according to claim 1, wherein when a coolant is passed through the tortuous conduit, the one or more flow constrictors are configured to cause an increase in a dwell time of the coolant inside the tortuous conduit. 4. A cooling apparatus according to claim 1, wherein when a coolant is passed through the tortuous conduit the one or more flow constrictors are located and configured to effectuate an increase of an exhaust temperature of the coolant within the coolant exhaust duct. 5. A cooling apparatus according to claim 1, wherein the first longitudinal body comprises a first material having a first thermal conductivity and the second longitudinal body comprises a second material having a second thermal conductivity that is less than the first thermal conductivity. 6. A cooling apparatus according to claim 1, wherein the second longitudinal body comprises a plurality of radially extending and axially spaced apart members that form in part the tortuous conduit. 7. A cooling apparatus according to claim 6, wherein the plurality of radially extending and axially spaced apart members comprise ring elements having a through opening formed longitudinally therein, at least one or more of the through openings comprising the one or more constrictors, the through openings of axially adjacent ring elements not being longitudinally aligned with one another. 8. A cooling apparatus according to claim 7, wherein the through opening of at least some of the ring elements are longitudinally aligned with one another. 9. A cooling apparatus according to claim 7, wherein the through opening of adjacent ring elements are spaced one hundred eighty degrees apart. 10. A cooling apparatus according to claim 1, wherein the plurality of flow constrictors of different cross-sectional areas are configured to create a backpressure in the tortuous conduit when a coolant is passed through the tortuous conduit. 11. A cooling apparatus according to claim 1, wherein the plurality of flow constrictors includes a first flow constrictor having a first cross-sectional area and a second flow constrictor having a second cross-sectional area, the first flow constrictor being located nearer the inlet of the tortuous conduit than the second flow constrictor, the second cross-sectional area being greater than the first cross-sectional area. 12. A cooling apparatus according to claim 1, wherein the plurality of flow constrictors includes a first flow constrictor having a first cross-sectional area and a second flow constrictor having a second cross-sectional area, the first flow constrictor being located nearer the inlet of the tortuous conduit than the second flow constrictor, the second cross-sectional area being less than the first cross-sectional area. 13. A cooling apparatus according to claim 1, wherein the second longitudinal body comprises a plurality of radially extending and axially spaced apart members that form in part the tortuous conduit, the plurality of flow constrictors comprising through holes in the plurality of radially extending and axially spaced apart members. 14. A cooling apparatus according to claim 13, wherein the plurality of radially extending and axially spaced apart members comprise ring elements having the through openings respectively formed longitudinally therein, the through openings of axially adjacent ring elements not being longitudinally aligned with one another.
