🔷Thermoelectric Peltier Product Overview

The TEC1-09902 is a semiconductor cooling module designed for precision temperature control over an extremely large area at high voltages and low power consumption. With dimensions of 30 × 60 mm, it features a large, rectangular, symmetrical package design that provides an exceptionally generous heat exchange area. It is optimized for industrial-grade laser modules, large medical and cosmetic devices, industrial analytical instruments, communication base stations, and other equipment requiring temperature control over an extremely large area with limited power budgets.

This product is available in three crystal configurations—K26, K34, and K42—with thicknesses of 5.0 mm, 5.8 mm, and 6.6 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 12.0 V, a maximum current of 2.2 A, a maximum cooling power of 26 W, and an internal resistance of 4.25 Ω.

The extra-large 30×60mm 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 26W, the 30mm width and 60mm 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 12.0V high-voltage, 2.2A low-current drive design—which is highly compatible with common platforms such as industrial power supplies (12V), telecommunications equipment power supplies, and automotive power supplies, eliminating the need for complex power conversion. The combination of high voltage and low current minimizes line losses, making it suitable for long-distance wiring and distributed temperature control systems. The high internal resistance of 4.25Ω ensures precise current control at low currents, 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 that combines 96% alumina ceramic (0.76mm) with 0.4mm oxygen-free copper; the thick copper layer ensures uniform heat diffusion across the 60mm × 30mm ultra-large surface area, preventing localized hot spots. It comes standard with 22 AWG silicone rubber leads (100 mm in length), capable of safely carrying a current of 2.2 A. 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, and large laboratory equipment. It is the ideal choice for precision temperature control requirements involving large surface areas, high voltage, and low power consumption.

🔷TEG Module Product Applications

1. Temperature Control for Large Industrial Laser Modules

Large industrial semiconductor laser modules generate a significant amount of heat during operation, and temperature fluctuations directly affect the stability of the output wavelength and power. The TEC1-09902’s extra-large 30×60 mm surface area matches the packaging of large laser modules, providing uniform temperature control coverage along the 60 mm length. Its 12.0 V operating voltage is compatible with common industrial power supply platforms, ensuring stable output wavelength and power.

2. Temperature Control for Large Medical and Aesthetic Devices

The cold/hot therapy probes of large medical aesthetic devices (such as large-scale photorejuvenation systems and medical-grade cryolipolysis devices) require extensive contact area and precise temperature control. The TEC1-09902 achieves alternating cold and hot modes by switching the current direction; its 30×60mm ultra-large surface area provides greater contact coverage, while its 26W power ensures rapid attainment of the set temperature, thereby enhancing treatment efficacy and user experience.

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 TEC1-09902 provides a stable, constant-temperature environment; its ultra-large coverage area effectively 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 in equipment such as communication base stations and large optical modules generate concentrated heat during operation. The TEC1-09902 can be used for active cooling of these critical components. Its 12.0V voltage is fully compatible with common power supply platforms for communication equipment, its 30×60mm surface area covers large heat-generating areas, and its 26W power output meets the thermal management requirements of base station equipment.

5. Temperature Control for Industrial Laser Processing Equipment

Optical components in large industrial laser processing equipment are subject to thermal deformation during operation, which affects processing accuracy. The TEC1-09902 provides active temperature control to maintain a constant temperature for optical components, ensuring processing accuracy. Its high assembly pressure of 4.5 kg ensures a tight bond between the extra-large cooling plate and the heat sink, making it suitable for the vibrations and shocks typical of industrial environments.

6. Temperature Control for Large Medical Diagnostic Equipment

Reaction modules in large medical devices, such as in vitro diagnostic (IVD) equipment and chemiluminescence analyzers, require a strictly controlled, constant-temperature environment. With its large coverage area, maintenance-free operation, and stable performance, the TEC1-09902 is well-suited to meet the demands of medical equipment for long-term reliability and large-area temperature control.
