🔷Tec Thermoelectric Cooler Product Overview

The TEC1-19503 is a semiconductor cooling module designed for precision temperature control of extremely large areas, high power, and high voltage. 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 equipment requiring temperature control over extremely large areas and handling high thermal loads, such as high-power industrial laser modules, large medical and cosmetic devices, industrial analytical instruments, and telecommunications base stations.

This product is available in three crystal configurations—K10, K18, and K26—with thicknesses of 3.4 mm, 4.2 mm, and 5.0 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 30×60mm rectangular package allows it to be embedded within high-power laser modules, medical devices, industrial equipment, and other applications. While ensuring a maximum cooling temperature difference of 70°C and high-power cooling of 72W, 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. This product features a 24V high-voltage, 3.0A current drive design, making it highly compatible with common industrial power supplies (24V), telecommunications equipment power supplies, and automotive 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 that combines 96% alumina ceramic (0.76 mm) with 0.4 mm oxygen-free copper. The relatively thick copper layer ensures uniform heat diffusion across the 60 mm × 30 mm surface area, preventing localized hot spots. It comes standard with 22 AWG silicone-coated leads (200 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.

This product is typically used for temperature control in high-power, large-scale industrial laser modules; large medical and cosmetic equipment; temperature stabilization in industrial analytical instruments; heat dissipation in telecommunications base station equipment; industrial laser processing equipment; and large medical diagnostic equipment. It is the ideal choice for high-voltage, high-power, precision temperature control applications requiring coverage of very large areas.

🔷Semiconductor Cooler Product Applications

1. Temperature Control for High-Power, Large-Scale Industrial Laser Modules

High-power, large-scale 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 TEC1-19503’s extra-large 30×60 mm surface area is compatible with the packaging of large laser modules, providing uniform temperature control coverage along the 60 mm length. Its 72 W high power quickly addresses thermal shock during laser startup, 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 TEC1-19503 achieves alternating cold and hot modes by switching the current direction; its 30×60 mm ultra-large surface area provides greater contact coverage, while its 72 W power ensures rapid attainment of the set temperature, 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 TEC1-19503 provides a stable, constant-temperature environment; its 72W power effectively manages heat generated by the detector itself, while the ultra-large contact area ensures temperature consistency across all regions of the detector.

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 TEC1-19503 can be used for active cooling of these critical components. Its 24.0V voltage is fully compatible with common power supply platforms for communication equipment, its 30×60mm surface area covers large heat-generating areas, and its 72W power output meets the cooling demands of high-power 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 TEC1-19503 provides active temperature control; its high power of 72W effectively manages the substantial heat generated during high-power laser processing, maintaining a constant temperature for optical components and ensuring processing accuracy.

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 TEC1-19503 is well-suited to meet the demands of medical equipment for long-term reliability and large-area temperature control.
