1. A cylindrical portable refrigerator comprising:
a lid assembly comprising a lid coupled with a lid bottom cover for fastening the lid assembly to an internal upper portion of a PCM chamber assembly;
a grill assembly comprising a top base, a pump bracket, a middle base, a bottom base;
wherein the top based hold the pump bracket, wherein the top base is coupled with the middle base, and wherein the middle base is coupled with the bottom base;
a cooling-coil assembly comprising a feeding tube, a top elbow, a bottom tube, a cooling coil, wherein the top elbow is installed between the cooling coil and the feeding tube to enable a change of direction of a liquid and couples the feeding tube with the cooling coil, and wherein the cooling coil is coupled with the bottom tube;
a thermo-electric cooler pump comprising a liquid pump with a Peltier effect system, and wherein the thereto-electric cooler pump is coupled with the cooling coil, wherein the thermos-electric cooler pump comprises:
a chiller/heater component, wherein the chiller/heater component is fixed to the case component, and wherein the chiller/heater component penetrates the case component such that a portion of the chiller/heater component is inside the case component and is wetted by the liquid while the other part of chiller/heater component is outside of the case component and is dry, wherein there is a seal around the chiller/heater component so that liquid does not escape in a vicinity of the chiller/heater component, and wherein the chiller/heater component comprises an electron flow to a thermal heat transfer by means of the Peltier effect,
wherein the thermos-electric cooler pump causes the liquid to flow from the inlet port, over the wetted side of chiller/heater component and out of case through the exit port;
wherein the chiller/heater component is energized so that electrons of the liquid flow in a positive direction to remove heat from the liquid, wherein the flow of the liquid is directed from the inlet port to the exit port by a specified geometry of the case component and the impeller component, wherein when electrons are made to flow in a positive direction within the chiller/heater component, a wetted side of the chiller/heater component is driven to lower temperatures and a dry side to a higher temperature, wherein when electrons are made to flow in a negative direction within the chiller/heater component, a wetted side of chiller/heater component is driven to higher temperatures and a dry side to the lower temperature, and wherein the wetted side of the chiller/heater component comprises a plurality of sets of regularly spaced and parallel elongated elements through which the liquid flows, wherein plurality of sets of regularly spaced and parallel elongated elements are placed in series along the traversal of the liquid;
the phase change material (PCM) chamber assembly that holds the cooling coil, wherein the PCM chamber is placed within an outer cylinder, and wherein a bottom portion of the PCM chamber assembly is coupled with the grill assembly, and wherein the PCM chamber assembly is plastered with a PCM material; and;
a sleeve assembly forming a portion of the outer cylinder, and
wherein the cylindrical portable refrigerator includes a handle.
