🔷Element Peltier Product Overview

The TEC1-19501 is a semiconductor cooling module designed for ultra-large-area, high-voltage, ultra-low-power precision temperature control. With dimensions of 30 × 60 mm, it features a large, rectangular, symmetrical package design that provides an exceptionally generous heat exchange area. It is specifically optimized for industrial-grade laser modules, large medical and cosmetic devices, industrial analytical instruments, and communication base stations—all of which require temperature control over an extremely large area while operating within extremely tight power consumption budgets.

This product is available in three crystal configurations: K20, K30, and K40, with thicknesses of 4.4 mm, 5.4 mm, and 6.4 mm, respectively, corresponding to maximum cooling temperature differences of 60°C, 65°C, and 70°C (under a hot-end temperature of Th=40°C) . It features a maximum voltage of 24.0 V, a maximum current of just 1.4 A, a maximum cooling power of 34 W, and an internal resistance of 13.37 Ω.

The extra-large 30×60 mm rectangular package allows it to be embedded within large laser modules, medical devices, industrial equipment, and other applications—while ensuring a maximum cooling temperature difference of 70°C and a cooling power of 34 W, the 30 mm width and 60 mm length provide an extremely generous heat exchange area, helping to evenly distribute cooling capacity across the large surface area of the load. The core advantage of this product lies in its drive design featuring a high voltage of 24V and an ultra-low current of 1.4A—making it highly compatible with common platforms such as industrial power supplies (24V), telecommunications equipment power supplies, and automotive power supplies, without the need for complex power conversion. The combination of ultra-high voltage and ultra-low current minimizes line losses (I²R), making it suitable for long-distance lead wiring and distributed temperature control systems. The ultra-high internal resistance of 13.37 Ω ensures precise current control at the ultra-low current of 1.4 A, enabling the drive circuit to achieve high-precision constant-current regulation and thereby deliver stable temperature control. The substrate is manufactured using a sintering process combining 96% alumina ceramic (0.76 mm) and 0.4 mm oxygen-free copper; the thick copper layer ensures uniform heat diffusion across the ultra-large 60 mm × 30 mm surface area. It comes standard with 22 AWG silicone-coated leads (200 mm in length), capable of safely carrying a 1.4 A current. Sealed with 704 silicone rubber around the perimeter, it is fully solid-state, noise-free, and vibration-free, ensuring stable and reliable operation.

This product is typically used in applications such as temperature control for large industrial laser modules, large medical and cosmetic equipment, temperature stabilization for industrial analytical instruments, heat dissipation for telecommunications base station equipment, industrial laser processing equipment, and large medical diagnostic equipment. It is the ideal choice for precision temperature control requiring high voltage and ultra-low power consumption across an extremely large area.

🔷Peltier Cooling Element Product Features

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

The extra-large 30×60 mm rectangular package provides an extremely generous heat exchange area, facilitating uniform heat transfer to the surface of large-area loads, making it ideal for large-scale temperature-controlled equipment.

2. High-voltage, ultra-low-current design for excellent system compatibility

With a maximum voltage of 24.0V, it is highly compatible with common industrial power supplies (24V), telecommunications equipment power supplies, and automotive power platforms. The ultra-low current of 1.4A minimizes line losses, making it suitable for long-distance wiring.

3. Ultra-low power consumption operation, energy-efficient and high-performance

With a maximum current of only 1.4A and a maximum power of just 34W, it achieves an excellent balance between ultra-low power consumption and deep cooling within its extra-large package, making it suitable for industrial equipment with strict energy efficiency requirements.

4. Deep cooling capability with a large temperature difference across a vast surface area

It achieves a maximum temperature difference of 70°C at an ultra-low power consumption of just 34W, with the cold end reaching as low as approximately -30°C, covering all application scenarios from conventional cooling to deep cooling.

5. Three Chip Options for Flexible Adaptation

Three chip configurations are available: K20 (60°C), K30 (65°C), and K40 (70°C). Users can flexibly select the appropriate model based on their target cooling depth.

6. Three Thickness Options to Suit Different Spaces

Thicknesses are 4.4 mm, 5.4 mm, and 6.4 mm. The K40 model, at 6.4 mm thick, provides ample space for the cooling elements, enabling deep cooling down to 70°C over a very large area.

7. Ultra-high internal resistance design for precise current control

With an internal resistance of 13.37 Ω, precise control of a 1.4 A current at 24.0 V is easier to achieve. This places lower demands on the drive circuit and is suitable for high-precision constant-current source drives.

8. High-Quality Substrate for Uniform Heat Dissipation Across an Extra-Large 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 the extra-large 60 mm × 30 mm surface area.

9. High Adaptability to Higher Assembly Pressures

The recommended assembly pressure is 4.5 kg (0.25 kg/cm²), ensuring that the extra-large cooling plate makes tight contact with both the heat sink and the surface being cooled, effectively reducing contact thermal resistance.

10. Sealed Protection, Strong Environmental Adaptability

The 704 silicone rubber perimeter seal provides excellent moisture, dust, and shock resistance, enabling the unit to withstand complex industrial environments with high humidity and significant temperature fluctuations.

11. Bidirectional Temperature Control, Dual-Function Single Core

Simply reversing the input current polarity activates heating mode, making it suitable for precision temperature-control systems requiring bidirectional temperature regulation.

12. Zero Noise, Zero Vibration, Precision Operation

With an all-solid-state design, it operates completely silently and with zero vibration, making it ideal for high-precision industrial applications with strict noise and vibration requirements.
