Electromagnetic induction heat exchanger

Abstract

The invention discloses an electromagnetic induction heat exchanger. The heat exchanger is characterized by being provided with a columnar heater, wherein two ends of the columnar heater are provided with a connection thread respectively; at least two water inrush channels are formed in the heater; an insulation layer is arranged on the heater; an induction coil is wound on the insulation layer, is in a spiral shape and is connected with a power supply connector through a controller; the controller consists of a power supply processing circuit, a variable frequency oscillating circuit, a high-frequency amplifying circuit, a driving circuit, intelligently-controlled protective circuit and a wave shaping circuit; the coil is supplied with high-frequency and high-voltage pulse current; the heater generates whirling current under the action of a high-frequency electromagnetic field; and under the action of the whirling current, the temperature of a magnetically-conducting cylinder is risen, water inside the cylinder is heated and flows in a naturally circulating mode, and heat is dissipated to space through a radiator. Besides, in the heat exchange process, the water which flows through the water inrush channels can be well magnetized, so contact area is increased, heating speed is increased, and the temperature difference of the water and the heater is low; moreover, the electromagnetic induction heat exchanger has the advantages of environment friendliness, energy conservation, long service life and the like.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, in particular to an electromagnetic induction heat exchanger with novel structure, energy saving and safe use. Background technique [0002] As we all know, with the development of the national economy, people's lives are getting better and better. Various cars and electrical appliances have entered the homes of ordinary people. Heating equipment, showers and domestic hot water devices are becoming more and more popular. Now a kind of heating in winter It is central heating. This heating method will provide heating regardless of the temperature within the specified heating period. If it is not within the heating period, it will not provide heating even in a severe cold current. Its disadvantages are inflexible use, waste of energy, and high costs. One is air conditioners, electric heaters, gas heat exchangers, and coal-fired furnaces. The disadvantages of these heating and heat exchange de...

[0002] As we all know, with the development of the national economy, people's lives are getting better and better. Various cars and electrical appliances have entered the homes of ordinary people. Heating equipment, showers and domestic hot water devices are becoming more and more popular. Now a kind of heating in winter It is central heating. This heating method will provide heating regardless of the temperature within the specified heating period. If it is not within the heating period, it will not provide heating even in a severe cold current. Its disadvantages are inflexible use, waste of energy, and high costs. One is air conditioners, electric heaters, gas heat exchangers, and coal-fired furnaces. The disadvantages of these heating and heat exchange devices are low heat exchange efficiency, high usage costs, poor safety, and unhygienic use. In recent years, people have invented many electric heating devices. For water heating heat exchangers, one of them is to directly heat water by using resistance heating control heat, which has poor safety and high requirements for the exchanged water quality; the other is to heat the resistive heat generating body. Electricity generates heat, which is then indirectly heated through insulating heat transfer oil or water. The disadvantage is that the heat exchange efficiency is low and electric energy is wasted.
