3-1616265-3

3-1616265-3 is a theromoelectric cooling generator; otherwise known as a peltier device. It functions in essentially the opposite way of a heat pump. While a heat pump pumps in heat from a cold area to a warm, a peltier device pumps out heat from a warm area to a cold. The device requires an input of electricity to achieve its cooling effect.

Application field

Most peltier devices are used for cooling electronic components in which a reliable and quiet cooling system is necessary. Since the peltier effect does not require moving parts, it is ideal for applications that require silent operation, such as computer hard drives and cooling microprocessors. Peltier modules are also widely used in various manufacturing processes and for research purposes. In addition, they are also used as heating and cooling elements on thermoelectric chillers and high-end thermoelectric cooling hoses.

Working principle

The 3-1616265-3 utilizes the Peltier effect to operate. The Peltier effect is a process by which an electric current flows through two differing metals and leads to a temperature differential. This temperature differential results in heat being transferred from one side to the other. By connecting two wires to a peltier module, one side becomes cold while the other side becomes hot.

The peltier module is made up of two ceramic plates filled with Bismuth Telluride (Bi2Te3) or Bismuth Telluride Sulfide (Bi2Te3S). These materials possess a property known as the Seebeck effect which refers to an exchange of electrons between two junctions when hot and cold temperatures are applied to them. This voltage difference between the two junctions is called the “Peltier voltage” and it is directly proportional to the current applied.

The Peltier effect occurs when electric current passes through a thermocouple junction. The boiling and condensing of electrical charges at the interface causes the temperature difference across the two junctions to be shifted. This heat is then dissipated by connecting a thermal load such as a heatsink or fan to the module. The resulting temperature difference between the two sides are then utilized for cooling or heating applications.

In summary, the 3-1616265-3 relies on the Peltier effect to transfer heat from one side to the other. It requires an input of electricity to achieve its cooling effect, and is best utilized in quiet applications that require little maintenance such as cooling electronic components or on thermoelectric chillers and cooling hoses.
