Peltier Device TEG Thermelectric Module Peltier Cooler , Thermoelectric Generators
How do we know which model is suitable for us?
a. Confirm the ambient temperature (Th)
b. Confirm the required temperature of the cooling space or objects (Tc)
c. Confirm the application’s heat load power (Q, the heat need to be removed or lowered)
d. Determine the required cooling capacity (Qc, considering heat loss, it is recommended Qc = 1.5 * Q)
e. Find out TE products from the catalog, whose maximum heat pumping capacity (Qmax) matches with the Qc worked out by step #4 (±5W), and then refer to the expected Current and Voltage to pick out a suitable product.
If the single product could not meet the requirement, you can also use series or parallel connect multiple products to get higher performance, the quantity = Qc / Qmax (Single products).
Thermoelectric power generating module (TEG) is one kind of power generating device which uses
the Seebeck Effect to convert heat source into electricity directly. It has the characteristics of compact structure, reliable performance, maintenance-free, working without noise, low-carbon and green. The heat source of TEG is extremely extensive. It will generate DC electricity continuously as long as there is temperature difference between both sides of module. Besides thermoelectric material, the factor which affects the generating capacity and conversion efficiency of TEG is the temperature difference. The larger temperature difference, the more generating capacity and higher conversion efficiency will be obtained.
