A：The cooling performance of a TEA can be improved by optimizing the heat sink, improving the thermal contact between the TEC and the heat sink, and using a higher efficiency TEC. Please contact us for specific guidance on improving the cooling performance of a TEA.

A：The power consumption of a TEA depends on various factors such as the operating voltage, current, and temperature difference. Huajing can provide specifications or guidelines on the power consumption of their specific TEC product.

A：TEAs can be used in vacuum environments, but the specific operating conditions and requirements must be taken into consideration. Please consult us to determine the suitability of a TEC for a specific vacuum environment application.

A：The temperature of a TEA can be controlled using a temperature control circuit that regulates the power supply to the device. The temperature control circuit can be adjusted to maintain the desired temperature range.

A：The maximum temperature difference that a TEA can achieve depends on various factors such as the operating conditions, the heat load, and the size of the device. Huajing can provide specifications or guidelines on the maximum achievable temperature difference for the your specific TEC product.
