Bi Sb compound Thermoelectric semiconductor materials that exhibit the best thermoelectric properties at relatively low temperatures.
Bi Te compound Thermoelectric semiconductor materials that exhibit the best thermoelectric properties near room temperature. Bi Te alloys are often used for thermoelectric refrigeration.
Closed circuit system temperature controller The temperature control device with temperature sensor (thermocouple, thermistor, RTD, etc.) can transmit or feedback temperature data to the control system. Through the feedback data, the control system automatically adjusts the output power to maintain the target temperature unchanged.
Tandem cooler The cooler and the cooler are connected together in parallel series. This combined structure can obtain higher power.
Single stage cooler The most basic thermoelectric cooler is electrically connected in series and thermally connected in parallel through a single-layer thermocouple. Under no load condition, the maximum temperature difference generated by the single-stage cooler is about 70 ° C.
Thermal conductive silicone grease It is a kind of fat like material that can improve the heat exchange between two contact surfaces by filling the micropores formed due to the surface roughness. The vast majority of thermal conductive silicone grease, such as transistor heat dissipation silicone grease or heat combined heat dissipation silicone grease, is added with zinc oxide in the silicone grease. There are also heat-conducting greases without silicone grease. Compared with heat-conducting silicone grease, they have better performance but higher price.
Lead telluride Thermoelectric semiconductor materials with the best thermoelectric performance in the temperature range of 250 ° - 450 ° C. It is often used in the field of thermoelectric power generation.
