Intermediate frequency electronic heating and warming device

Abstract

This invention is a heating device, especially an intermediate frequency electron heating device. It saves energy, non-polluted and intelligent controllable. It also has high thermal efficiency. It includes power source, water tank and circulating valve. Oscillating circuit, which generates intermediate frequency alternating voltage and alternating current, connects to the intermediate frequency electron heating device that generates alternating magnetic field and electromagnetic oscillation. The said oscillating circuit is controlled by controlling system. The intermediate frequency electron heating device is a magnetic metal container, with the heating coil at external part and liquid at internal part. Tandem radiating fins form the pipeline system. The water tank and circulating valve are connected to from circulating system. The intermediate frequency electron heating device, pipeline system and circulating system are connected in series to form the heating circulating loop. This invention can fulfill central heating.

Description

technical field [0001] The invention relates to a heating device, in particular to an intermediate frequency electronic heating device. Background technique [0002] At present, intermediate frequency heating technology is an existing mature heating technology, which has been widely used in metal smelting and heat treatment industries. Electromagnetic oscillation produces skin effect, that is, thermal energy surface, which was proposed by the experts of the former Soviet Union and used in the heat treatment industry to successfully solve the problems of machine tool guide rail quenching and gear surface quenching. However, the products produced by applying the medium frequency heating technology to the heating field are still the first in my country. [0003] There is a four-month heating period in the Beijing area, and the main heating methods are centralized heating methods such as coal, natural gas, and electric heating oil. Direct heating electric heating has low therm...

AI Technical Summary

Problems solved by technology

Direct heating electric heating has low thermal efficiency and high cost, so it is not suitable to be widely promoted

However, problems such as high energy consumption, low energy utilization rate, and environmental pollution are urgent problems to be solved in metropolises such as Beijing.

In recent years, although some of them have changed to clean energy for heating, such as gas, infrared, etc., due to the problems of unreasonable energy utilization, large waste, and high operating costs, it is difficult to promote it on a large scale.
