Thermal - Thermoelectric, Peltier Modules

The Peltier module, also known as the thermoelectric module, is one of the most versatile and popular components of thermal heat pumps. Originally developed in the mid-19th century, Peltier modules revolutionized the study of heat transfer. Nowadays, Peltier modules are used in a wide range of applications, ranging from medical and energy-saving devices to refrigeration and climate control. This article will discuss the application fields and working principles of Peltier modules, with the specific example of the 387001835 model.

Application Fields

Peltier modules are often used in applications where the efficient transfer of heat is necessary. They can be used in electronics to keep components cool, in sustainable energy solutions to increase energy efficiency, and in laboratory experiments to study heat transfer. They are used extensively in medical applications, such as cryotherapy, thermography and thermocouple devices.

Peltier modules are also widely used in refrigeration and climate control. In these applications, the Peltier module is used to transfer heat from one space to another. This process of transferring heat, as opposed to traditional air conditioning, is much more efficient, and can be used to provide temperature control in enclosed spaces. In addition, Peltier modules are often used to regulate temperature in automobiles and in heating/cooling systems.

Working Principles

Peltier modules are based on the Peltier effect, which was first described by French physicist Jean Charles Athanase Peltier in 1834. The Peltier effect is the process by which electricity is used to transfer heat. When an electric current is applied to the module, the junction of two dissimilar metals, known as the Peltier junction, begins to transfer heat from one side to the other.

The Peltier module is constructed from two sets of Peltier junctions, which are connected in series or in parallel. When an electric current is passed through the module, the Peltier junctions move heat from one side to the other. The Peltier module can be used as a heat pump, or as a heat sink, depending on the direction of the electric current.

The 387001835 model specifically is a thermoelectric module with a total power of 40W, a thermal resistance of 0.5°C/W, and a maximum operating temperature of +75°C and -55°C.

ConclusionPeltier modules are becoming more and more popular as an efficient and versatile component of thermal heat pumps. The 387001835 model specifically is a thermoelectric module used in a variety of applications, from medical to climate control. The operation of the module is based on the Peltier effect, which is the process by which electricity is used to transfer heat from one side to the other.
