🔷 Product Overview

The TEC12708 Peltier Effect Cooler is a 40×40mm thermoelectric cooling component designed for compact thermal management systems. Based on the thermoelectric effect, it transfers heat from one side of the module to the other when direct current is applied.

Compared with conventional compressor-based cooling systems, thermoelectric cooling modules have no moving parts inside the module and allow localized temperature control in compact assemblies. They can be integrated into electronic devices, laboratory instruments, optical equipment, and customized temperature control systems.

As a thermoelectric cooler, the TEC12708 can be considered for applications where size, electrical control, and solid-state operation are important. Final suitability depends on the required cooling capacity, operating temperature, thermal load, and heat dissipation design.

KKG supports thermoelectric cooling product selection based on customer application requirements. Please provide your target temperature, heat load, supply voltage, installation space, and operating environment to help identify a suitable solution.

🔷 Product Features

1. Compact 40×40mm Format

The module's 40×40mm footprint supports integration into compact cooling assemblies where installation space is limited.

2. Solid-State Cooling

Thermoelectric cooling operates through the movement of heat under an applied electrical current, without a mechanical compressor inside the module.

3. Localized Temperature Control

The module can be incorporated into systems that require cooling at a specific component or surface.

4. Flexible System Integration

The TEC12708 can be evaluated for use with heat sinks, fans, temperature sensors, controllers, and other thermal management components.

5. Suitable for Customized Designs

Electrical wiring, mounting arrangements, heat dissipation structures, and control strategies can be evaluated according to the requirements of the complete device.

6. Application-Dependent Performance

Cooling results depend on the selected operating point and the surrounding thermal design. Appropriate engineering evaluation is recommended before mass production.

🔷 Product Structure

🔷 Operation Principle / Work Principle

A thermoelectric cooler operates through the Peltier effect. When direct current passes through the module's semiconductor elements, heat is absorbed at one ceramic surface and released at the opposite surface.

The heat-absorbing side becomes the cold side, while the heat-releasing side becomes the hot side. Reversing the direction of the current reverses the hot and cold sides.

However, the hot side must dissipate both the heat removed from the cooled object and the electrical power consumed by the module. If heat dissipation is insufficient, the hot-side temperature rises and cooling performance decreases.

For this reason, a complete thermoelectric cooling system typically requires a suitable heat sink, appropriate thermal contact, a compatible power supply, and, where necessary, temperature monitoring and control.

🔷 Product Testing

Product testing helps verify whether a thermoelectric cooler meets the required electrical, dimensional, and thermal specifications.

Depending on the manufacturer's quality-control process, relevant inspection items may include:
