Induction heating device based on electromagnetic vortices

Abstract

Traditional heating systems that use gas, electric elements or electrical resistance have low efficiency, high energy consumption and high costs. In gas combustion-based systems, the emission of environmental pollutants is also a serious problem. On the other hand, element-based electric heating systems, although they are not polluting, have high energy losses and require high power consumption, which makes them unsuitable for use in renewable energies. This invention is an induction heating system based on electromagnetic eddies, designed to replace fossil fuel-based heating systems. The system consists of one or more toroidal core coils that, when an alternating current is passed through them, create a magnetic field and induce eddy currents in a conductive metal surface that absorbs heat. The heat generated is transferred to a heating fluid in a heat exchanger and through pipes to radiators and is distributed to the environment by convection.

Description of the invention Title of the invention Induction heating device based on electromagnetic vortices Technical background of the relevant invention This invention is related to heating devices and systems, and its technical field is related to the knowledge of electricity and electromagnetism. Technical problem and stating the objectives of the invention Traditional heating systems that operate on the basis of fossil fuels or resistance elements usually have low efficiency and high energy waste. Also, these systems pose environmental and economic challenges due to the production of polluting gases or high electricity consumption. The present invention, by utilizing electromagnetic induction and creating electromagnetic vortices, transfers heat more efficiently, increasing energy efficiency and reducing electricity consumption compared to traditional methods. The aim of this system is to provide an optimal and sustainable alternative to existing heating methods that can be used in industrial and domestic applications. A description of the state of the prior art and the history of developments related to the claimed invention. British scientist Michael Faraday is widely credited with discovering the phenomenon of electromagnetic induction in the early 19th century. Faraday demonstrated that changes in a magnetic field can induce an electric current in a nearby medium. This discovery laid the foundation for the development of generators and transformers. In the electromagnetic vortex induction heating device, the closest available records of this process are used: Patent No. JP2020187854A (B2) entitled "Electromagnetic induction heating device" can be cited. The article S2352146521002337, titled "The Resonant Induction Heating Method", was presented in 2021 and fully describes this process at high frequency. Induction heating has been used as an effective method of heat generation, especially in heavy industries such as metal smelting. This technology uses electromagnetic induction to create eddy currents in conductive materials and thereby generate heat. In the field of domestic applications, induction cookers are an example of the use of this technology. These cookers directly heat the cooking utensils by creating an electromagnetic field, which leads to reduced heat loss and increased efficiency. However, the use of induction heating systems for environmental heating on a domestic or industrial scale has received less attention. There are some radiant floor heating systems that transfer heat using electromagnetic waves; But these systems operate mainly based on thermal radiation and do not utilize the principles of electromagnetic induction. By combining the principles of induction heating and creating eddy currents in specific surfaces or materials, the present invention provides a process that can be effectively used to heat various spaces.This innovative approach allows the benefits of induction heating to be exploited in a wider range of applications. Providing a solution to an existing technical problem along with an accurate, sufficient, and integrated description of the invention There is a technical problem. Traditional heating systems that operate with gas, electric elements or electrical resistance have low efficiency, high energy consumption and high costs. In gas combustion-based systems, the emission of environmental pollutants is also a serious problem. On the other hand, element-based electric heating systems, although they are not polluting, have high energy losses and require high power consumption, which makes them unsuitable for use in renewable energies. Proposed solution This invention is in the field of electric heating systems and induction heating technologies. This system uses the principles of electromagnetic induction and electromagnetic vortices to generate heat and transfer it to a fluid. This technology can be an efficient alternative to fossil fuel-based heating systems. This invention is an induction heating system based on electromagnetic eddies, designed to replace fossil fuel-based heating systems. An induction heating system based on electromagnetic eddies, which uses the principles of electromagnetic induction to convert electrical energy into thermal energy and transfer it to a heating fluid. This system consists of one or more cored or toroidal coils that, when an alternating current passes through them, create a magnetic field and induce eddy currents in a heat-absorbing metal surface. Eddy currents generate heat in conductive materials. (For example, copper and steel have high absorption capacity in this process and the entire surface of the part is heated uniformly.) The heat generated in this way is transferred to a heating fluid (such as water or oil) and then distributed to the environment.The field created in the vicinity of the copper ring core (to create magnetic eddy currents on the surface of the metal core of the device) heats the metal and by passing fluid (for example, water) through the copper tube ring, it absorbs its heat and heats the water. The heating distribution process is carried out by transferring the hot water through the fluid circuit to the plate exchanger (to exchange and transfer the heat created in the device). The innovative feature of this system is the optimization of the heat transfer process and the reduction of energy consumption, which increases efficiency compared to resistance heating methods. Also, to increase the life of the coils and ensure stable operation, a cooling system based on a heat sink and fan is used to prevent excessive temperature increase of the toroidal coils. The system is designed to be able to adjust the excitation frequency of the coils, which optimizes the amount of heat generated in the metal core. This system can be used in domestic and industrial heating and can be powered by renewable sources (such as solar panels). Its compact design, reduced power consumption, and high efficiency make it a suitable alternative to traditional heating systems.

This system has the following features: • One or more toroidal coils designed to produce an alternating electromagnetic field. • An electrical power source that supplies alternating current to excite the coils. • A metal core that, under the influence of the magnetic field, creates eddy currents and generates heat. • A heat chamber (heat sink) designed to transfer heat from the metal core to the heating fluid. The heat chamber (heat sink) is made of a material with a high thermal conductivity to transfer heat from the metal core to the heating fluid with minimal losses. The heat chamber (heat sink) has a thermal insulation layer to control the heat generated by the copper toroidal core and protect the heat transfer to the device's toroids. This prevents energy loss and increases the heating efficiency of the system. • The cooling system using fans reduces the temperature of the toroids. • A fluid circulation system that facilitates heat transfer to the desired environment •A temperature and power control system that optimizes system performance and regulates output temperature. 1. Generating heat using magnetic induction: • In this method, an induction coil receives high-frequency alternating current from a power source (the current value is defined as 7 amps to 20 amps, depending on the amount of heating required for domestic use) and produces a strong magnetic field, which causes eddy currents to be generated on the surface of a metal core (usually steel or copper). • Eddy currents generate heat due to the electrical resistance of the core. 2. Heat transfer to the heating fluid: • The heated core transfers heat to water or other liquids by direct contact. • The heated water through the heat exchanger can be used for space heating, domestic water heating, or energy supply for industrial applications. 3. Precise and intelligent control: • The system has a temperature and power control circuit that automatically adjusts the output power. • The use of temperature and flow sensors increases energy efficiency. • The device has the ability to automatically turn on and off to prevent the device from being plugged in and wasting energy. The device's thermostat includes thermal sensors and an intelligent electronic circuit that automatically adjusts the input power and maintains the temperature of the heating fluid within the defined temperature range. • The cooling system is used to cool the heat sink of the device's toroid cores. It is used by fans to control the temperature and reduce the temperature of the coils to prevent overheating and reduce the life of the equipment. 4. Compatibility with renewable energies: • The power consumption of this system is low and can be powered by solar energy or energy storage batteries (the power required by the device is about 3000 watts or an average consumption of 15 amps, which is provided by solar panels and high-power batteries of 20 amps, which is practical and economical.) • This feature makes the system suitable for remote areas or places where there is no access to stable electricity. 5. No need for moving parts and reduced depreciation: • In this system, there are no moving mechanical parts, as a result, depreciation and maintenance costs are minimized. 6. Increased safety and reduced risks: • Compared to gas heaters, this system does not produce any flames or dangerous gases. • Reducing the risk of fire, explosion, and gassing is one of the main advantages of this method. This invention is an optimal and safe alternative to existing heating systems that reduces energy consumption, increases efficiency, and enables the use of clean energy.The use of electromagnetic induction and eddy currents in this system allows heating to be done locally, quickly, and with minimal energy loss, which distinguishes it from traditional methods.
