🔷TEC Cooler Product Overview

The TEC1-06302 is a semiconductor cooling module designed for precision temperature control of medium-sized areas and medium power levels. With dimensions of 15 × 30 mm and a rectangular symmetrical package design, it provides ample heat exchange area while maintaining excellent spatial adaptability. It is optimized for compact devices requiring a medium-sized temperature-controlled area, such as laser modules, medical and cosmetic equipment, and analytical instruments.

This product is available in three crystal configurations—K10, K16, and K22—with thicknesses of 3.0 mm, 3.6 mm, and 4.2 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 7.6 V, a maximum current of 2.2 A, a maximum cooling power of 17 W, and an internal resistance of 2.69 Ω.

The 15×30 mm rectangular package allows it to be embedded inside devices such as laser modules, medical probes, and analytical instruments—while ensuring a maximum cooling temperature difference of 70°C and a cooling power of 17 W, the 15 mm width provides an excellent heat exchange area, helping to evenly transfer cooling capacity to the load surface. Designed to operate at 7.6V and 2.2A, this product is highly compatible with common two-cell lithium-ion battery series-connected power supply platforms (7.4V), eliminating the need for complex power conversion. The 2.69Ω internal resistance provides moderate current control sensitivity, facilitating precise constant-current regulation by the drive circuit. The substrate is manufactured using a sintering process combining 96% alumina ceramic (0.76 mm) and 0.2 mm oxygen-free copper, resulting in a lighter overall weight and lower thermal mass, which facilitates rapid temperature response. The thin copper layer design reduces thermal inertia, enabling faster temperature changes and making it suitable for applications requiring frequent temperature adjustments. The 704 silicone rubber perimeter seal ensures a fully solid-state, noise-free, and vibration-free operation, delivering stable and reliable performance.

This product is typically used in applications such as laser module temperature control, hot and cold probes for medical and cosmetic devices, temperature stabilization for analytical instruments, PCR temperature control modules, and heat dissipation for telecommunications equipment. It is an ideal choice for precision temperature control requirements in medium-sized spaces with medium power demands.

🔷Thermoelectric Cooler Peltier Product Applications

1. Temperature Control for Laser Modules

Semiconductor laser modules are temperature-sensitive during operation, and temperature fluctuations directly affect the stability of output wavelength and power. The TEC1-06302’s 15×30 mm dimensions are compatible with standard laser module packaging, and its 17 W power rating enables rapid response to thermal shock during laser startup, ensuring stable output performance.

2. Cold/Hot Therapy Probes for Beauty Devices

Cold and hot therapy probes in home-use and professional beauty devices (such as photorejuvenation devices and cryolipolysis hair removal devices) need to reach the set temperature quickly. The TEC1-06302 achieves alternating cold and hot modes by switching the current direction; the low thermal inertia provided by its 0.2 mm-thick copper layer enables faster temperature transitions, enhancing the user experience.

3. Temperature Control for Analytical Instruments

Detectors in scientific instruments such as spectrophotometers, chromatographs, and thermal analyzers must operate under constant-temperature conditions to reduce dark current and improve the signal-to-noise ratio. The TEC1-06302 provides a stable, constant-temperature environment, and its vibration-free, noise-free solid-state operation is well-suited for noise-sensitive laboratory environments.

4. Temperature Control Module for Portable PCR Instruments

The reaction chamber of portable PCR instruments requires rapid cycling within the 60–95°C temperature range. The TEC1-06302’s 2.2A current enables rapid heating and cooling, while its thin copper layer design reduces thermal inertia, helping to improve temperature control response speed.

5. Temperature Control for Communication Equipment

Critical chips in equipment such as communication base stations and optical modules generate concentrated heat during operation. The TEC1-06302 can be used for active cooling of these critical components, and its 7.6V operating voltage is compatible with common power supply platforms for communication equipment.

6. Temperature Control for Medical Diagnostic Equipment

Reaction modules in medical devices such as in vitro diagnostic (IVD) equipment and chemiluminescence analyzers require a strictly controlled, constant-temperature environment. With its compact size, maintenance-free operation, and stable performance, the TEC1-06302 meets the long-term reliability requirements of medical equipment.

🔷Peltier Cooling Module Installation and Usage Recommendations

Assembly Pressure: Recommended 0.5 kg (0.25 kg/cm²). It is recommended to apply thermal grease (thermal conductivity > 3 W/m·K) evenly to both surfaces, with a thickness of 0.05–0.1 mm.

Installation Orientation: The 15×30 mm rectangular TEC has a defined dimensional orientation. During installation, ensure that the 30 mm long side aligns with the length of the device being cooled to achieve optimal thermal contact coverage.

Hot-end Heat Dissipation Requirements: With a moderate power consumption of 17 W, it is recommended to use an extruded aluminum heat sink measuring at least 20 × 35 × 15 mm, combined with a low-speed fan (airflow > 5 CFM), or to dissipate heat through the device’s metal enclosure to meet the requirements.

Power Supply Requirements: Maximum voltage 7.6V, maximum current 2.2A. It is recommended to use two lithium-ion batteries connected in series (7.4V) or a regulated power supply rated at 7.6V/2.5A or higher. Power supply ripple should be < 50mV.

Lead Wires: The standard 26 AWG silicone-coated wires fully meet the 2.2A requirement and do not need to be replaced.

Current Limitation: Do not exceed 2.2A. It is recommended to connect a 2.5A self-resetting fuse in series for overcurrent protection.

Condensation Prevention Measures: During deep cooling (cold end < 0°C), fill the area around the cold end with desiccant or add insulation, and apply conformal coating to the lead solder joints.

Storage Conditions: Temperature < 120°C, humidity < 60% Rh; packaged in a sealed bag with desiccant.

Maximum Temperature: Must not exceed the solder melting point of 138°C; when soldering manually, keep the soldering iron temperature below 280°C, and limit soldering time to < 5 seconds.
