Description

Induction Plastic Water Heater {Induction Plastic Water Heater}

When a high frequency current passes through an induction coil formed by twisting a plurality of thin coils into a disk shape or an elliptic plate shape, an eddy current caused by an electromagnetic induction phenomenon is generated on a heating plate formed on the front and rear surfaces of the induction coil. Direct heating water heater with high heat efficiency composed of Induction Heater system that generates Joule heat (heat generated by resistance).

It is designed to contact the insulated gate bipolar transistor where high heat is generated when the high frequency is produced and the inflow pipe where cold water is introduced, so that a separate cooling means for cooling the hot insulated gate bipolar transistor is unnecessary.

Water introduced into the inlet pipe is primarily heated by the heat generated from the insulated gate bipolar transistor.

Although the first heated water is heated second by a heating plate formed on the front side of the induction coil, and the second heated water is heated third by another heating plate formed on the back side of the induction coil, the top plate and the water tank are molded of plastic and the water heater Induction plastic water heater with simple manufacturing process and light weight of water heater.

Conventional water heaters generate heat by burning gas, which is fossil fuel, to generate heat, and heat is generated by resistance when electric power passes through a nichrome wire formed at the center of a pipe filled with magnesium oxide inside a tank containing water. Most of the low-temperature electric water heaters of the indirect heating method that heats the water in the tank with the heat.

Gas water heaters that generate heat by burning fossil fuels have a number of problems such as additional costs according to storage and supply of fuel, carbon generated during combustion, and toxic gas generated during combustion.

In addition, conventional electric water heaters are more convenient to install than gas water heaters and have less risks during operation, but are consumed a lot of power by an indirect heating method with low thermal efficiency. It has become a major factor in generating harmful substances in the manufacturing process and raising the manufacturing cost, so that it is unable to supply consumers with low cost thermally efficient water heaters.

The low heat efficiency, which is a disadvantage of the conventional electric water heater, is solved by the direct heating method with high heat efficiency,

Insulated Gate Bipolar Transistor (IGBT), a semiconductor device capable of high-speed high-speed switching as an essential element for the induction heater method, is a separate device that cools the insulated gate bipolar transistor even when high heat is generated during high frequency production. To cool the insulated gate bipolar transistor without cooling means,

Water heater with its own light weight that simplifies the manufacturing process by minimizing welding work in the manufacturing process and minimizes the generation of harmful substances.

When the high-frequency current produced by the insulated gate bipolar transistor passes through an induction coil formed by twisting a plurality of thin coils into a disc or elliptic plate, electromagnetic induction occurs on the heating plates formed on the front and back of the induction coil. Joule heat (heat amount generated by resistance) is generated by eddy current (swirl current).

A heating plate composed of such an induction heater method becomes a heating element that generates heat, and thus the water heater of the direct heating type with high thermal efficiency is constructed by directly heating water.

In addition, a separate cooling means is required to cool the insulated gate bipolar transistor by cooling the insulated gate bipolar transistor by configuring the insulated gate bipolar transistor in which high heat is generated when the high frequency is produced, and the inflow pipe where cold water is introduced. Do not

No additional means for cooling the hot insulated gate bipolar transistor is configured by contacting the inflow pipe where cold water flows from the outside and the hot insulated gate bipolar transistor during high frequency production.

Heated parts that produce heat are molded from plastic to minimize welding work, which simplifies the manufacturing process and minimizes manufacturing costs, making it possible to supply electric water heaters that are easy to use and have good thermal efficiency to consumers at low prices.
