Heat exchanging thermal liquid container

A user configurable modular heat exchanging thermal liquid container system, said system comprising:

• a main body partially defining a liquid reservoir structured and operable to retain a liquid;
• a plurality of upper PCM units that are removably connectable to the main body, each upper PCM unit comprising:
• an upper unit base;
• an upper unit PCM pod disposed adjacent an underside of the upper unit base;
• and
• an upper unit PCM disposed within the upper unit PCM pod, wherein the PCM of each upper PCM unit has a respective melting temperature that is different than melting temperature of the other upper unit PCMs;
• and
• a plurality of lower PCM units that are removably connectable to the main body, each lower PCM unit comprising:
• an lower unit base;
• an lower unit PCM pod disposed adjacent a top side of the lower unit base;
• and
• an lower unit PCM disposed within the lower unit PCM pod, wherein the PCM of each lower PCM unit has a respective melting temperature that is different than melting temperature of the other lower unit PCMs,
• wherein the upper PCM units are interchangeably removably connectable to the main body and the lower PCM units are interchangeably removably connectable to the main body such that system can be configured with any combination of upper PCM unit and lower PCM unit.
