Reinforced heat transfer high-temperature phase-change heat storage type electric boiler

Abstract

The invention discloses a reinforced heat transfer high-temperature phase-change heat storage type electric boiler, and relates to the field of heating equipment. The reinforced heat transfer high-temperature phase-change heat storage type electric boiler structurally comprises a heat preservation shell, a circulating fan, a heat storage module, an electric heating element, an air-water heat exchanger, an automatic control system and a shell main body. The high-temperature phase-change heat storage type electric boiler can store heat at night at the electricity utilization valley and release the heat in the daytime at the electricity utilization peak, so that the load caused on a public power transmission line in the daytime is reduced, and the potential safety hazard is reduced under thecondition that the heating efficiency is improved. In the aspect of control, the high-temperature phase-change heat storage type electric boiler can also realize the switching use among three controlmodes of automatic control, manual operation control and remote control, and the intelligent control can be achieved on the fan heating output, a return water supply system and the heat storage module. According to the reinforced heat transfer high-temperature phase-change heat storage type electric boiler, besides an alarm function is achieved when an abnormal fault occurs to a system, an automatic abnormity processing function is also achieved so that the equipment safety can be guaranteed.

Problems solved by technology

[0002] In winter, due to the low air temperature, it is necessary to heat the room, especially in the north of my country, it is generally necessary to carry out central heating. At present, the main heating method used is coal-fired. Burning a large amount of fossil fuels releases a large amount of dust, toxic and harmful gases, etc., causing air pollution. In recent years, environmental problems have become increasingly prominent. In most cities in the north, most of the time in winter is accompanied by smog. In order to To reduce the pressure on the environment, the state has launched a series of "coal to electricity" policies to encourage the use of electric heating, reduce carbon dioxide emissions, and protect the environment. Electric boiler heating systems are gradually being adopted by people

[0003] In cold weather conditions in winter, due to the greater demand for heating, when the temperature drops, people will increase the power of the heating system at the same time. On the one hand, the public transmission line will reach a very high load for a period of time. , has potential safety hazards. On the other hand, the power supply capacity in some areas is insufficient and may not be able to meet everyone's heating needs at the same time. Therefore, the regenerative electric boiler provides a good solution for the contradiction between power supply and demand.

[0004] At present, the existing regenerative electric boilers are mainly based on sensible heat storage, but due to the small amount of heat stored in the heat storage and the large structure, if you want to get more heat, you must increase its volume to achieve it, which limits the sensible heat. The Development of Heat Storage Electric Boiler

Most of the latent heat phase change heat storage electric boilers on the market are mainly medium and low temperature, and the heat exchange efficiency is low, they cannot fully store heat, and waste energy, the control method is single, and automation cannot be realized. Therefore, the present invention provides an enhanced heat transfer boiler. Thermal high-temperature phase-change thermal storage electric boiler, the heat storage module of this thermal storage electric boiler adopts a zigzag heat exchange plate, which is arranged at intervals with the heating elements, which avoids the disadvantage that the whole boiler cannot store heat due to damage to a group of heating elements, and makes The boiler can store more heat at the same time
