CP70137

Thermal - Thermoelectric, Peltier Modules

CP70137 is a thermal - thermoelectric, Peltier module employed for various applications. A Peltier module is a device that uses the Peltier effect to create a temperature difference between two electrical junctions. Peltier modules, when powered, can function as heating or cooling devices depending on the polarity of the applied voltage. CP70137 is used extensively in industries and for research purposes where its ability to provide precise cooling or heating in a narrow temperature range is of paramount importance.

Application Field

The CP70137 Peltier module is suitable for applications requiring precise cooling. Applications may include the thermal management of small robotics, such as cooling robotic arm and camera. Such robotic arms and cameras require precise control over temperature in order to operate properly. Additionally, the CP70137 is used extensively by industries for the cooling of electronic devices such as computers, CCTV cameras and communication equipment.

The CP70137 is also used in the research and industrial sectors, for the precise cooling or heating of test articles and components. Experiments often require accurate temperature control in order to verify the results. In this case, the Peltier module is employed due to its excellent performance in precise temperature control.

The CP70137 can also be used in consumer devices such as refrigerators and air conditioners. Its superior cooling and heating capabilities make it suitable for use in these applications. Moreover, its small size, low power consumption and low cost make it ideal for consumer products.

Working Principle

The CP70137 Peltier module works on the basis of the thermoelectric effect. A thermoelectric effect is the transfer of energy between two electrical junctions or between electrical conductors and thermal conductors. In the CP70137 module, thermoelectric effects take place between two semiconductor layers or junctions, which have different electrical characteristics. When an electrical current is applied to the module, one junction will become hotter, while the other junction will become cooler. This effect is known as the Peltier effect.

The CP70137 Peltier module is usually powered by a DC power source. When the voltage is applied to the junctions, the temperature difference between the two junctions will increase, and this will be represented by an increase in the power consumption of the module. The greater the voltage applied to the junctions, the greater will be the temperature difference between the two junctions. This relationship is known as the Peltier-Seebeck law.

In addition, the power consumption of the CP70137 module is also affected by the temperatures of the two junctions. When the temperatures of the two junctions are equal, the power consumption of the module will be zero. As the temperature difference between the two junctions increases, the power consumption of the module increases accordingly.

The CP70137 Peltier module can be used for cooling or heating, depending on the polarity of the voltage applied to the module. When a positive voltage is applied to the module, it will act as a cooler and the hot junction will become cooler while the cold junction will become hotter. Conversely, when a negative voltage is applied to the module, it will act as a heater and the cold junction will become hotter while the hot junction will become cooler.

Conclusion

The CP70137 Peltier module is a versatile device used in numerous applications requiring precise cooling or heating. It is powered by a DC power source, and works on the basis of the thermoelectric effect known as the Peltier effect. The CP70137 is suitable for use in industrial and consumer applications, and is renowned for its ability to provide precise temperature control in a narrow temperature range.
