Thermal - Thermoelectric, Peltier ModulesThermoelectric modules (TEMs) are solid-state devices that produce electrical power when subjected to a temperature difference between two of their surfaces. They are composed of semiconductor material that can absorb energy from one side while releasing energy from the opposite side with alternating hot and cold surfaces. The temperature difference between these surfaces is known as the “temperature gradient”, or “thermoelectric effect”. The resulting energy is used to generate electrical current. The electrical power generated by a TEM is proportional to the temperature difference between its two sides, as well as the number of thermoelectric elements used.TEMs are widely used in fields such as energy conversion, thermal management, sensing, and thermoelectric cooling and heating. In terms of energy applications, they are typically used to harvest waste heat, converting it into usable electrical energy. TEMs are also used for cooling and refrigeration, as they can remove thermal energy from an object and dissipate it into the environment.The 430040-513 is a two-stage thermoelectric module. It consists of a pair of bismuth telluride (Bi2Te3)-based thermoelectric elements embedded between two copper heat sink blocks. The 430040-513 is a “staggered-finger” design, meaning that the Bi2Te3 elements are configured such that one side is higher than the other side, creating a higher temperature gradient across the two surfaces. The 430040-513 is rated at up to 15.5 watts at a temperature gradient of > 60°C. In operation, the 430040-513 generates electrical energy when a temperature difference is created across its two sides. This temperature difference can be achieved by connecting it to two different heat sources, such as a hot plate and a cold plate. When this occurs, the two sides of the thermoelectric module draw heat away from each other due to their heat capacities. This causes the two sides to reach different temperatures and results in an electrical output.The 430040-513 is also able to take advantage of the “Seebeck effect”, which is the production of a voltage when two plates of different temperatures are placed in contact. This allows the 430040-513 to be used as a temperature sensor and/or a generator of electrical energy.The 430040-513 is designed for a range of applications, including refrigeration, power generation, sensing, and thermoelectric cooling and heating. As a thermal management device, it can be used to regulate temperature in various electronic devices, including computers, electronics, and medical equipment. It is also used in renewable energy applications, such as solar thermal systems, that can benefit from its ability to convert heat into electricity.In conclusion, the 430040-513 is a two-stage thermoelectric module that can be used for a variety of applications, including energy conversion, thermal management, sensing, and thermoelectric cooling and heating. Its ability to generate electrical power from a temperature difference and its Seebeck effect make it an excellent choice for applications that require energy efficiency and reliability.
