🔷Product Structure

🔷Operation Principle / Work Principle
Based on Peltier effect. When DC current passes through the thermoelectric module, heat will transfer from one ceramic side to the other side. One surface absorbs heat for cooling, the other releases heat. Reverse the current direction to switch between cooling and heating.

🔷FAQ
Q1: What is the maximum temperature difference of this 20203.3mm 1A peltier cooler?
A: The max ΔT depends on heat sink condition. Good heat dissipation can reach the rated temperature difference of the module.

Q2: Can this peltier cooler work continuously 24 hours?
A: Yes, stable continuous operation is supported with proper heat dissipation and operating current within rated 1A.

Q3: Do you support OEM and custom peltier cooler modules?
A: We provide OEM service, custom size, wire length and surface treatment according to customer drawings.

Q4: Is the peltier cooler waterproof?
A: Standard ceramic peltier module is not waterproof. It needs sealing treatment if used in humid environment.
