Thermoelectric system consisting of alternating trapezoid elements with increased figure of merit
View Patent ↗In one aspect, a thermo-electric system comprising alternating trapezoid elements with increased figure of merit comprises: a thermal spreader system comprising: a top plate comprising aluminum, and a bottom plate comprising aluminum; and an interior portion of the thermo-electric system comprising the alternating of trapezoid elements comprising a plurality of P-trapezoid elements and a plurality of N-trapezoid elements, wherein each P-trapezoid element alternates with an N-trapezoid element.
1 . A thermo-electric system with alternating trapezoid elements with increased figure of merit comprising:
a thermal spreader system comprising:
a top plate comprising at least one heat spreader material,
a bottom plate comprising the at least one heat spreader material; and
an interior portion of the thermo-electric system comprising an alternating arrangement of the trapezoid elements comprising a plurality of P-trapezoid elements and a plurality of N-trapezoid elements,
wherein the top plate is forty (40) millimeters by forty (40) millimeters,
wherein the bottom plate is forty (40) millimeters by forty (40) millimeters,
wherein a thickness of the thermal spreader system is 4.65 millimeters,
wherein a first row of the plurality of P-trapezoid elements and the plurality of N-trapezoid elements comprises a first P-trapezoid element coupled with a Positive Peltier wire via a first copper pad,
wherein each P-trapezoid element alternates with each N-trapezoid element,
wherein each basal surface of each P-trapezoid element has a larger surface than each top surface of each P-trapezoid element and a basal surface of each N-trapezoid element has a smaller area than each top surface of each N-trapezoid element,
wherein the thermal spreader system is coupled with a Negative Peltier wire,
wherein the thermal spreader system is coupled with the Positive Peltier wire,
wherein a thickness of the top plate is 0.7 millimeters,
wherein a thickness of the bottom plate is 0.7 millimeters,
wherein a base length of each N-trapezoid element is 2.5 millimeters,
wherein each basal surface of each P-trapezoid element is coupled with the bottom plate,
wherein each basal surface of each N-trapezoid element is coupled with the top plate,
wherein a sidewall of each N-type trapezoid element forms an angle of 18° relative to a line that is perpendicular to the top plate and the bottom plate,
wherein the thermal spreader system is coupled with a side of a payload box that comprises aluminum of a portable refrigerator as a thermoelectric module, and
wherein the thermal spreader system transfers energy as heat from the payload box of a portable refrigeration system to a colder heat sink or heat exchanger,
wherein the aluminum is sprayed with a thermoplastic elastomer.
