🔷Thermoelectric Cooler Peltier Product Overview

The TEC1-13915 is a flagship industrial semiconductor cooling module designed for ultra-large-area, low-voltage, ultra-high-power-density precision temperature control. With dimensions of 80 × 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 and is optimized for equipment requiring ultra-large-area temperature control and extremely high thermal loads, such as large industrial equipment, ultra-high-power laser modules, medical imaging equipment, industrial analytical instruments, and other equipment requiring large-area temperature control and capable of handling extremely high thermal loads. It is the most powerful flagship model in the series.

This product is available in three chip configurations—K18, K28, and K38—with thicknesses of 4.7 mm, 5.7 mm, and 6.7 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 16.6 V, a maximum current of 15.0 A, a maximum cooling power of 249 W, and an internal resistance of just 0.86 Ω.

The extra-large 80×120mm rectangular package allows it to be embedded inside large industrial equipment, ultra-high-power laser modules, and similar applications—while ensuring a maximum cooling temperature difference of 70°C and ultra-high cooling power of 249W, the 80mm width and 120mm length provide an extremely generous heat exchange area, helping to evenly distribute cooling capacity across the surface of very large loads. This product features a 16.6V low-voltage, 15.0A drive design, making it compatible with common industrial power supplies (12V/24V requiring conversion) and telecommunications equipment power supply platforms. With an ultra-low internal resistance of 0.86Ω—the lowest in this series—Joule heat loss (I²R ≈ 193.5W) at 15.0A 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 × 80 mm surface area, preventing localized hot spots. It comes standard with 18 AWG silicone-coated leads (300 mm in length), capable of safely handling the high current of 15.0 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 is up to 24.0 kg (0.25 kg/cm²), ensuring 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 large industrial laser modules, medical imaging equipment, temperature stabilization for industrial analytical instruments, heat dissipation for telecommunications base station equipment, industrial laser processing equipment, and large-scale medical diagnostic equipment. It is the ideal choice for precision temperature control requirements involving extra-large, high-area spaces with low voltage and ultra-high power density.

🔷Peltier Cooling Module Product Features

1. Extra-large, symmetrical design with ample heat exchange area

2. Ultra-high-power cooling with robust performance

With a maximum current of 15.0 A and a maximum power of 249 W, it achieves ultra-high power density cooling within an extra-large, high-surface-area package, making it suitable for extra-large equipment with extremely high thermal loads.

3. Deep-Freeze Capability: Extra-Large Surface Area with Wide Temperature Differential

At an ultra-high power of 249W, it achieves a maximum temperature differential of 70°C, with the cold end reaching as low as approximately -30°C, covering all application scenarios from conventional cooling to deep-freeze applications.

4. Three Crystal Options for Flexible Adaptation

Three crystal configurations are available: K18 (60°C), K28 (65°C), and K38 (70°C). Users can flexibly select the appropriate model based on their target cooling depth.

5. Three Thickness Options to Suit Different Spaces

Thicknesses are 4.7 mm, 5.7 mm, and 6.7 mm. the K38 model, at 6.7 mm thick, provides ample space for the crystal grains to support ultra-large-area cooling, helping to achieve deep cooling down to 70°C.

6. Low-Voltage, High-Current Design for Excellent System Compatibility

With a maximum voltage of 16.6V and a maximum current of 15.0A, it can be adapted via step-down or step-up conversion on common power supply platforms, making it suitable for industrial applications requiring low-voltage, high-current drive.

7. Ultra-low internal resistance design for high energy conversion efficiency

With an internal resistance of just 0.86 Ω, it is the model with the lowest internal resistance in this series. Joule heating losses are effectively controlled even at a high current of 15.0 A, allowing more electrical energy to be converted into effective cooling capacity.

8. High-Quality Substrate, Uniform Heat Dissipation Across an Extra-Large Surface Area

The substrate is manufactured using a sintering process combining 96% alumina ceramic (0.76 mm) and oxygen-free copper (0.4 mm). The thick copper layer ensures that heat is evenly distributed and rapidly dissipated across an extra-large surface area of 120 mm × 80 mm.

9. Extra-Thick, Extra-Long Leads for Flexible Wiring in Large Equipment

Comes standard with 18 AWG silicone-coated wire (300 mm in length) to meet the demands of high-current transmission and wiring in extra-large equipment.
