The advantages and disadvantages of TEC and its development status (I)

Sunday, September 6, 2015 7:47:37 PM America/Los_Angeles

Thermoelectric cooler (TEC) is an ancient technology. As early as in the 1950’s, TEC has once set off a boom. When it is connected to a power supply, it can become cold, which is very popular among home appliance manufacturers. However, because of the poor performance of components, it failed to be applied in actual life. The key, which determines the rise of decline of materials and process of TEC, is to improve figure of merit and the cooling effect of the hot and cold end.

In order to meet the cooling requirement, TEC materials not only need N and P type semiconductor properties, but also need thermoelectric potential, electric conductivity and heat conduction rate of semiconductor added impurity. Production of traditional TEC materials mainly use zone-melting method and powder metallurgy method, but the production cost is very high and the equipment process is also very complicated. At home, the common used materials are on the basis of Bi2Te3, P type is Bi2Te3-Sb2Te3 and N type is Bi2Te3-Bi2Te3. The vertical zone melting method is used for extracting crystal materials. The optimization coefficient of thermoelectric elements produced in this way is only 3×103K-1, which can result in low cooling efficiency. When the temperature difference is 50℃, the cooling coefficient is only 0.06. Only if the optimization coefficient is up to l3×103K-1, the cooling efficiency can be the same with the compression refrigeration efficiency.

Therefore, because of early technology and process constraints, the TEC efficiency is too low, so TEC haven’t received enough attention and application.

Advantages and application of TEC controllers

Saturday, September 5, 2015 10:56:53 PM America/Los_Angeles

Thermoelectric cooling uses the Peltier effect to create a heat flux between the junctions of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, being dependent on the direction of the current. Such an instrument is known as a Peltier device, a Peltier heat pump, solid state refrigerator, or thermoelectric cooler (TEC). It can be used either for heating or for cooling, although in practice the main application is cooling. It can be invoked as a temperature controller that either heats or cools.

The TEC5V4A-D is an electronic module designed for driving TECs (Thermo-Electric Coolers) with high stability in regulating the object temperature, extreme energy efficiency.

The module provides interface components for users to configure the desired object temperature range, i.e. set-point temperature range; maximum voltage across TEC, i.e. maximum TEC voltage; and the compensation network. The compensation network compensates the astronomical order thermal load and thus stabilizes the temperature control loop.

The TEC5V4A-D comes with a high stability low noise 3.0V voltage references which can be utilized to setting the desired object temperature by using a POT (potentiometer) or a DAC (Digital to Analog Converter). When utilizing this reference for setting the set-point temperature, the set-point temperature error does not depend on this reference voltage.
