Principle and Application of Thermo-magnetic Generator

Thermo-magnetic Generator is a device that utilizes temperature differences and magnetic fields to generate electrical energy.

Different people have different names for it. Some call it Thermal Activation Generator (TAD), while others call it Thermal Activation Device (TAD).

Thermo-magnetic Generators are currently very popular. Let’s focus on analyzing its principle and application.

The Composition of Thermo-magnetic Generator

It is composed of temperature sensors, magnetic generators, and control circuits, it can convert temperature into electrical energy and output it.

Specifically, it is composed of thermosensitive magnetic materials with magnetostrictive effects and some electronic components.

The Working Principle of Thermo-magnetic Generator

It utilizes the thermal properties of magnetic materials to change at different temperatures.

When the temperature changes, the magnetization state of magnetic materials changes accordingly, causing deformation of thermosensitive magnetic components during thermal expansion and contraction, resulting in changes in magnetic flux and ultimately generating induced potential in the coil.

The Advantages and Disadvantages of Thermo-magnetic Generator

The advantages of the thermo-magnetic generator including:

• Simple detection and efficient operation.
• It can be applied to various heat sources, such as solar energy, industrial waste heat, geothermal energy, etc., to convert these thermal energy into electrical energy.
• It has no noise.
• It will not emit pollutants that have an impact on the atmosphere.
• It does not require any external power supply to work, it is itself a temperature detection and current generation device.
• Unlike conventional power smart devices, there are no internal power storage components.
• Its sensitive components are fusible metals, memory alloys, or glass balls, which are temperature-sensitive and can respond quickly to temperature changes.
• It has good stability and a long service life.
• Compared to traditional power generation technology, it does not require fuel and is environmentally friendly.
• It can be applied in various industries and months to generate electricity, thereby driving the operation of some industrial equipment, such as to start aerosol fire extinguishing devices.

But it also has some disadvantages, such as:

• It generates a small current and is unable to drive high-power equipment.
• It is not easy to store.
• It requires a higher temperature difference to generate sufficient electrical energy.

The Applications of Thermo-magnetic Generator

The thermo-magnetic components are widely used in various fields due to their pollution-free, sustainable, and long-distance input of electrical energy, including the following areas but not limited to:

• Energy fields, such as Solar energy, photovoltaic energy, and wind energy.
• Fire protection fields, such as gas suppression systems, aerosol generators, ABC super-fine Dry chemical powder fire extinguishers, etc.
• Electricity fields, such as Distribution cabinets, transmission facilities, etc.
• Industrial facilities, such as workshops, warehouses, etc.
• In the agricultural field, such as farmland irrigation, small agricultural houses, etc.
• In the telecommunications field, such as telecommunications base stations, communication cabinets, etc.
• New energy storage systems, energy storage compartments, energy storage cabinets, and energy storage containers.
• The engine compartment of vehicles and heavy machinery.

Summary

The emergence of thermomagnetic generators has provided us with a new way of power generation and a more environmentally friendly, reliable, and efficient energy solution, with unlimited development potential.

I believe that in the future, it will be further improved and promoted, bringing greater convenience and benefits to our lives and work.
