Abstract

Using the Lenz's law of the principle that the magnetic field caused by the induced current becomes the direction of disturbing the magnetic flux change, the phosphorescent copper pipe is heated with the high heat generated by the resistance generated when the disk rotates, and the water penetrating the inside is rapidly heated. This is a magnetic heater supplied with hot water.

The cooling of the brushless motor is a magnetic heater that controls temperature by controlling the number of rotations of the motor by controlling the temperature controller when cold water first flows into the hollow cylindrical motor fixing frame at all times to prevent overheating of the motor.

Lenz's Law, Phosphate Copper Pipe with "U" Bending

Description

Magnetic Heater

Along with the circumference of the "O" ring-shaped disk made of nylon, which is a thermosetting resin, ND magnets for 300 ° C are evenly attached at the intersection of the N and S poles, and a brushless motor is embedded in the middle of the disk. Phosphoric acid copper pipe through which hot water passes at intervals is bent into a "U" shape around the front and back of the disc.

Since the motor and the disc are integrated, the motor rotation speed is the rotation speed of the magnet-mounted disc. Using Lenz's law, the direction of the blast furnace induced electromotive force appears in the direction of preventing the change of magnetic flux through the coil surface. In other words, the magnetic field caused by the induced current is a direction that prevents the change of the magnetic flux, so the phosphorescent copper pipe is heated by the high heat generated by the resistance generated during operation, and the water penetrating the inside is rapidly heated to supply hot water. It is a heater.

The temperature of water is controlled by the rotation sensor when the user operates the temperature controller in the room. The slower the rotation, the lower the temperature, and the higher the rotation, the higher the temperature.

This product has been tested as a finished product, and it is heated to 800 degrees in only 15 seconds when operating at 3 ~ 4000rpm, so it is very suitable for mass production type as a high efficiency eco-friendly boiler. It is much smaller than existing gas boilers, oil boilers and electric boilers. Since there is no contact between the pipe and the disc, there is no damage from heat and rotation.

It belongs to electric boiler, electric system among boiler field and belongs to eco-friendly high efficiency boiler or electric heater.

Application of the principle of the motor used for power by generating torque due to rotation when power is supplied It is a device that uses high heat generated by resistance due to eddy current generated during operation when the law of Lenz is established when it is rotated. It is already manufactured as a finished product and is ready for mass production.

The electric current flows along with the change of magnetic flux of the conductor such as copper, and the magnetic force moves in the direction opposite to the direction of the magnet movement, and the resistance is generated.

The material of the disc that does not conduct the heat of the copper pipe where hot water passes should be used and it should be manufactured by optimizing the size and quantity of the magnet due to the size change according to industrial and home use.

Nylon, a thermosetting resin, is used to prevent melting at high temperatures of more than 300 degrees, and mass production by mold manufacturing can significantly reduce manufacturing time and cost.

Compared to commercial kerosene boilers, battery type electric boilers, and gas boilers, the structure is very simple, light and easy to manufacture, and the price is very low. In addition, the use of electrical energy that does not require combustion, there is no air pollution, which can significantly reduce the environmental damage and operate with less power, so the user's burden of electricity fee is very low.

It is a high-efficiency, eco-friendly electric heater that is made of magnet, conductor (copper pipe) and noiseless brushless motor by applying Lenz's law.
