hermoelectric Module Durability tester

Among the thermoelectric materials that are the core materials of thermoelectric elements, Bi2Te3 metal is strongly oxidized in the atmosphere Especially for metal produced by existing zone melting process The strength of the inner metal is less When cutting Bi2Te3 produced by bar type ingot according to the specific purpose of 0.8mm ~ 2mm, it may cause defective operation due to mechanical impact of inner metal according to 5 cutting processes in total.

Accordingly, there are various systems for verifying durability of thermoelectric elements It is common practice to verify the durability of a thermoelectric device by applying electrical shock and thermal shock through a cycling test.

Cycling test verification of our thermoelectric devices

Cycling Testing Methods

For thermoelectric elements of cold and warm, a temperature sensor is placed on a cooling device equipped with a thermoelectric element for durability measurement Change the temperature of the thermoelectric element from 0 ° C to 90 ° C to 0 ° C as one cycle and continue to perform cycling tests for your standard number of times.

Durability certification conditions.

• Number of cycling: Thermocouple should operate normally up to your standard number of times.
• When the resistance of the thermoelectric device was measured after the cycle test If the change in resistance of the thermoelectric element is within +/- 5% of the initial resistance measurement
