🔷TEC Module Product Overview
The TEC1-20203 is a semiconductor cooling module designed for ultra-large-area, high-power, industrial-grade precision temperature control. With dimensions of 50 × 100 mm, it is one of the largest models in the series. Featuring an ultra-large, rectangular, symmetrical package design, it provides an exceptionally generous heat exchange area and is optimized for large industrial equipment, ultra-high-power laser modules, medical imaging equipment, industrial analytical instruments, and other equipment requiring large-area temperature control with moderate power requirements.
This product is available in three crystal configurations—K32, K38, and K44—with thicknesses of 5.6 mm, 6.2 mm, and 6.8 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 3.0 A, a maximum cooling power of 72 W, and an internal resistance of 6.24 Ω.
The extra-large 50×100mm rectangular package allows it to be embedded within large industrial equipment, ultra-high-power laser modules, and similar systems—while ensuring a maximum cooling temperature difference of 70°C and a cooling power of 72W, the 50mm width and 100mm 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 24V high-voltage, 3.0A current drive design, making it highly compatible with common industrial power supplies (24V) and telecommunications equipment power platforms, eliminating the need for complex power conversion. The 6.24Ω internal resistance provides excellent current control sensitivity, enabling the drive circuit to achieve precise 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 relatively thick copper layer ensures uniform heat diffusion across the 100 mm × 50 mm ultra-large surface area, preventing localized hot spots. It comes standard with 20 AWG silicone rubber leads (300 mm in length), capable of safely carrying a 3.0 A current. 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 12.5 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-voltage, medium-power applications with extensive spatial coverage.
🔷Thermoelectric Cooler Module Product Applications
1. Temperature Control for Large Industrial Laser Modules
Large industrial semiconductor laser modules generate significant heat during operation, and temperature fluctuations directly affect the stability of output wavelength and power. The TEC1-20203’s 50×100 mm ultra-large surface area is compatible with the packaging of large laser modules, providing uniform temperature control coverage along the 100 mm length. Its 72 W power rating enables rapid response to thermal shocks during laser startup, ensuring the stability of output wavelength and power.
2. Temperature Control for Medical Imaging Equipment
Core sensors and detectors in large medical imaging equipment (such as CT scanners, MRI auxiliary temperature control systems, and PET detectors) require a strictly controlled, constant-temperature environment to ensure imaging quality. The TEC1-20203 provides a large-area, low-noise, vibration-free temperature control solution. Its 50×100 mm surface area can cover large detector arrays, and its 72 W power rating effectively manages heat generated by the detectors themselves. The 24 V operating voltage is compatible with common power supply platforms used in medical equipment.
3. Temperature Control for Large Analytical Instruments
Detectors in scientific instruments such as large spectrophotometers, chromatographs, and thermal analyzers must operate under constant-temperature conditions to reduce dark current and improve the signal-to-noise ratio. The TEC1-20203 provides a stable, constant-temperature environment; its 72W power rating effectively manages the heat generated by the detectors themselves; its extra-large coverage area ensures temperature consistency across all regions of the detector; and its vibration-free, noise-free solid-state operation is well-suited for noise-sensitive laboratory environments.
4. Temperature Control for Communication Base Station Equipment
Critical chips and power modules in large communication base stations and data center switching equipment generate concentrated heat during operation. The TEC1-20203 can be used for active cooling of these critical components. Its 24.0V voltage is fully compatible with the power supply platforms commonly used in communication equipment, and its 50×100 mm surface area covers large heat-generating areas, while its 72W power output meets the thermal management requirements of base station equipment.
