🔷Thermoelectric Cooling Element Product Overview
The TEC1-19525 is the ultimate flagship industrial semiconductor heat sink designed for ultra-large-area, top-tier extreme power density cooling. Measuring 60 × 120 mm, it is one of the largest models in the series. Featuring an extra-large, rectangular, symmetrical package design, it provides an exceptionally generous heat exchange area. Optimized for large-scale industrial equipment operating at extreme power levels, ultra-high-power laser modules, high-performance medical devices, and other applications requiring extensive temperature control over a large area and handling extremely high thermal loads, it is the most powerful, ultimate flagship model in the series.
This product is available in three die configurations—K10, K14, and K18—with thicknesses of 3.4 mm, 3.8 mm, and 4.2 mm, respectively, corresponding to maximum cooling temperature differences of 60°C, 65°C, and 70°C (under conditions where the hot-end temperature Th = 40°C). It features a maximum voltage of 24.0 V, a maximum current of 25.0 A, a maximum cooling power of 600 W, and an internal resistance of just 0.75 Ω.
Its extra-large 60 × 120 mm rectangular package allows it to be integrated into high-end, high-power industrial equipment, and ultra-high-power laser modules—while ensuring a maximum cooling temperature difference of 70°C and extreme power cooling up to 600W. The 60mm width and 120mm length provide an extremely generous heat exchange area, facilitating uniform heat transfer to the surface of very large loads. This product features a 24V high-voltage, 25.0A current drive design, making it highly compatible with common industrial power supplies (24V), telecommunications equipment power supplies, and other platforms. With an ultra-low internal resistance of 0.75Ω—the lowest in this series—Joule heat loss (I²R ≈ 468.8W) at 25.0A is effectively controlled, allowing more electrical energy to be converted into effective cooling capacity and delivering outstanding energy efficiency. The substrate utilizes a sintering process combining 96% alumina ceramic (0.76 mm) and 0.4 mm oxygen-free copper. The relatively thick copper layer ensures uniform heat dissipation across the extra-large 120 mm × 60 mm surface area, preventing localized hot spots. It comes standard with 18 AWG silicone-coated leads (300 mm in length, twin-wire configuration), capable of safely carrying the high current of 25.0 A. The 704 silicone rubber perimeter seal provides excellent moisture, dust, and shock resistance. The all-solid-state design ensures precise operation with zero noise and zero vibration. The recommended mounting pressure of up to 18.0 kg (0.25 kg/cm²) ensures that the extra-large cooling plate is tightly bonded to the heat sink and the surface being cooled, effectively reducing contact thermal resistance and withstanding vibrations and impacts in industrial environments.
This product is typically used in applications such as temperature control for top-tier, high-power large industrial laser modules, heat dissipation for large industrial equipment, high-performance medical devices, and high-power communication base stations. It is the ultimate flagship choice for cooling applications requiring extreme power density in extra-large, high-surface-area spaces.
🔷Thermoelectric Generation Product Applications
1. Temperature Control for High-Power Large Industrial Laser Modules
High-power large industrial semiconductor laser modules generate a significant amount of heat during operation. The TEC1-19525’s 600W peak power cooling capacity enables efficient temperature control over an extra-large 60×120mm area, stabilizing the laser temperature at the setpoint ±0.05°C. It is suitable for peak-power laser processing, optical communications, and LIDAR systems.
2. Heat Dissipation for Large Industrial Equipment
High-power electronic components and power modules in large industrial equipment generate concentrated heat during operation. The TEC1-19525 can be mounted directly on the component surface; its 600W maximum power rating provides robust active cooling, reducing core temperatures by more than 25°C and enhancing equipment reliability and lifespan.
3. Temperature Control for High-Performance Medical Equipment
High-end medical imaging equipment and large in-vitro diagnostic devices require a strictly controlled, constant-temperature environment. The TEC1-19525 delivers robust cooling performance thanks to its extra-large coverage area, maintenance-free operation, and stable performance.
4. Heat Dissipation for High-Power Communication Base Stations
High-power communication devices, such as 5G base stations and high-power transmitters, generate concentrated heat. The TEC1-19525 can be used for active cooling, and its 24.0V operating voltage is fully compatible with communication equipment power platforms.
🔷Thermoelectric Generator Modules Installation and Usage Recommendations
Assembly Pressure: Recommended 18.0 kg (0.25 kg/cm²). It is recommended to apply high-performance thermal grease (thermal conductivity > 5 W/m·K) evenly to both surfaces.
Hot-End Cooling Requirements (Critical): With a power consumption of 600 W, heat generation is extremely high. We recommend using a large extruded aluminum heatsink measuring at least 65 × 125 × 90 mm, paired with a high-airflow fan (airflow > 150 CFM), or implementing a water-cooling solution to ensure prompt heat dissipation from the hot end. The cooling efficiency of the hot end directly determines the lowest achievable temperature at the cold end.
Power Supply Requirements: Maximum voltage 24.0 V, maximum current 25.0 A. A regulated power supply rated at 24 V/30 A or higher is recommended. Power supply ripple < 50 mV.
Lead Wires: Standard configuration includes 18 AWG silicone-insulated wires (length 300 mm, twin-wire), rated for a safe current carrying capacity of 25.0 A.
Current Limit: Must not exceed 25.0A; it is recommended to connect a 30A self-resetting fuse in series.
Storage Conditions: Temperature < 120°C, humidity < 60% Rh.
Maximum Temperature: Must not exceed 138°C; soldering temperature < 280°C, duration < 5 seconds.
