Peltier with optimal levels of augmenting radiation
View Patent ↗A thermoelectric cooler including a thermoelectric junction and a radiation source. The thermoelectric cooler includes n-type material, p-type material, and an electrical power source. The radiation source emits ionizing radiation that increases electrical conductivity of the n and p type materials. Also detailed is a method of using radiation to reach high coefficient of performance (COP) values with a thermoelectric cooler that includes providing a thermoelectric cooler and a radiation source, with the thermoelectric cooler including an n-type material, p-type material, an electrical power source, and emitting ionizing radiation with the radiation source to increase the electrical conductivity which strips electrons from the n-type material, the p-type material, or both the n-type material and p-type material from their nuclei with the electrons then free to move within the material.
1. A thermoelectric converter comprising:
a thermoelectric cooler;
a radiation source;
wherein the thermoelectric cooler includes a hot source, a cold source, n-type material, and p-type material;
wherein the thermoelectric cooler creates a temperature difference between the hot source and the cold source;
wherein the n-type material and/or the p-type material are each a thermoelectric material chosen from: bismuth telluride, lead telluride, nickel oxide and silicon germanium;
wherein the radiation source emits ionizing radiation that causes atoms of the n-type material and/or the p-type material to ionize and free electrons, which increases electrical conductivity;
wherein the radiation source is an internal source;
wherein the internal source is a radioisotope dopant; and,
wherein the radiation source uses alpha or beta radiation.
2. The thermoelectric converter of claim 1 wherein the p-type material or the n-type material respond to the radiation source by changing material properties including the Seebeck coefficient or thermal conductivity.
3. The thermoelectric converter of claim 1 wherein the p-type material or the n-type materials respond to the radiation source over a specific range of temperatures.
