TE ingot and pellets-The BiTe-P/N-1thermoelectric ingot

Short Description:

The BiTe-P/N-1thermoelectric ingot is grown by Thermonamic with the alloy of Bi, Sb, Te, Se, special doping and our unique crystallizing processes. The Bi-Te based thermoelectric ingot is used to produce thermoelectric modules for cooling and heating applications, and converting heat into electricity. Generally, the figure of merit ZT of our p-type and n-type ingots is larger than 1 at 300K, and the good feature attracts many high-end customers. Meanwhile, our ingot is featured with good mechanical strength and high stability, providing the corner stone for producing the high performance and reliable Peltier cooling and power generation modules.  Our pellets can be cut  at 0.2X0.2X0.2MM, the Temp. difference can reach 74℃.

*Matters needing attention


Semiconductor cooler works with DC input power supply and must be equipped with special power supply.
1. DC power supply. The advantage of DC power supply is that it can be used directly without conversion. The disadvantage is that the voltage and current must be suitable for semiconductor coolers, and some can be solved by series and parallel connection of semiconductor coolers.
2. AC current. This is an ordinary power supply, which must be rectified to DC before it can be used for the cooler. Since the refrigeration device is a low-voltage and high current device, it is first applied with voltage reduction, rectification and filtering. In some cases, temperature measurement, temperature control and current control are added for convenience.
3. Since the semiconductor cooler is supplied by DC power supply, the ripple coefficient of the power supply must be less than 10%, otherwise it will have a great impact on the cooling effect.
4. The working voltage and current of the semiconductor cooler must meet the needs of the working device. For example, for the device with model tec1-12706, 127 is the couple logarithm of the cooling device, PN, and the working limit voltage of the cooler v = couple logarithm × 0.11 and 06 are allowed to pass through large current values.
5. The power on during the cold and heat exchange of the cooler must be restored to the room temperature at both ends (generally more than 5 minutes), otherwise it is easy to cause the line damage of the cooler and the rupture of the ceramic sheet.
6. The electronic circuits of semiconductor cooler power supply are common and can be found in general electronic technology reference books.
