🔷 Product Structure

🔷Operation Principle

Based on Peltier effect of thermoelectric modules. When DC current passes through N‑P thermoelectric pellet pairs, heat will transfer from cold side to hot side. Cold side absorbs heat to realize cooling; hot side releases heat which needs matched heat sink for heat dissipation. Reverse current direction will switch cooling mode to heating mode, realize bidirectional temperature adjustment.

🔷 Product Testing

Every 62*62*3.6mm industrial peltier cooler is 100% fully inspected before shipment, strictly testing all core indicators of thermoelectric modules to ensure high stability and consistency for industrial cooling, laser cooling, semiconductor temperature control and medical cooling applications. We adopt professional industrial testing standards to eliminate defective products and guarantee long-term continuous operation of the equipment.

Core Testing Items:

1. Electrical Performance Test: Accurately detect working voltage, working current, internal resistance and insulation resistance of thermoelectric modules to ensure no short circuit, no open circuit and stable electrical conductivity, meeting industrial-grade power supply requirements.

2. Cooling Performance Test: Test the maximum temperature difference, cooling speed and heat load bearing capacity of the peltier cooler under standard working conditions, verify the actual cooling efficiency, and ensure it matches the parameter standards of high-power thermoelectric modules.

3. Structural & Appearance Test: Check the flatness of ceramic substrate, firmness of welding points, integrity of lead wires and overall dimension accuracy (62*62*3.6mm) to avoid cracks, deformation and welding defects.

4. High and Low Temperature Cycle Test: Simulate extreme working environments of -40℃ to +80℃ to test the structural stability and performance durability of the thermoelectric modules, ensuring adaptability for long-term industrial on-site use.

5. Aging Test: Conduct continuous power-on aging test for hours to screen out products with unstable performance, effectively reducing the failure rate of thermoelectric modules in refrigeration equipment and precision temperature control systems.
