TEC1-12707 Thermoelectric Peltier Module – High-Efficiency Cooling Solution

The TEC1-12707 Thermoelectric Peltier Module is a high-performance solid-state heat pump designed for cooling or heating applications. Using the thermoelectric effect, it moves heat from one side to another using a low-voltage DC power supply. With a power rating of 70W, this module is widely used in mini refrigeration systems, CPU/gadget cooling, water chillers, temperature control devices, and scientific experiments.

Its durable construction and internal semiconductor elements provide long-term, maintenance-free operation. To achieve maximum cooling efficiency, the cold side must be paired with an appropriate heatsink or cooling fan, ensuring effective heat dissipation from the hot side.
