Abstract
The utility model provides an electric heating boiler, belonging to the electric heating apparatus, mainly dealing with the problem of the heat exchange rate of the boiler. The utility model comprises a boiler body and an electric heating device, and is characterized in that the electric heating device comprises a heating body, a sealed heat-pipe, a medium cavity, and a plurality of heating rods, wherein a superconducting medium is arranged in the sealed heat-pipe, liquid heat conducting medium is sealed in the medium cavity; the heating rods are all positioned in the liquid heat conduction medium in the medium cavity; one end of the heat-pipe is arranged in the medium cavity and sealed at the connection part with the medium cavity; the other end is positioned in a heating medium in the boiler body. An outlet pipe is arranged at the upper of the boiler body and a return pipe is arranged at the lower of the boiler body. The utility model has the advantages of high rate of heat exchange, rapid heating speed, compact structure, no pollution, high efficiency, no noise and easy fixing and maintenance. Meanwhile, the dry burning of the heating element can be avoided and the working reliability and the service life of the boiler are improved. The utility model is suitable for the heating in winter and the usage of hot water in daily life in ordinary families and small occasions.
Description
Affiliated technical field
The utility model relates to a kind of electric heater unit, is specially a kind of general family and small sized applications winter heating and daily life hot water electrically heated boiler.
Technical background
One of leading indicator of electrically heated boiler is the height problem of the thermal efficiency.The thermal efficiency is high more, and effect is good more concerning boiler, and is energy-conservation more.Though conventional electric heating boiler kind is more, the common drawback that exists is that the thermal efficiency is low, energy consumption is high.
Summary of the invention
In order to overcome the problems referred to above, the electrically heated boiler that provides a kind of thermal efficiency high is provided the purpose of this utility model.
The technical scheme that the utility model is dealt with problems is this kind electrically heated boiler, comprise boiler body and the fixing electric heater unit at the end within it, it is characterized in that described electric heater unit by calandria, be built-in with the sealing of superconductive medium heat pipe, and inner sealing form by the dielectric cavity of liquid heat-conducting medium; Heating rod all places liquid heat-conducting medium in the dielectric cavity, and heat pipe one end is positioned at dielectric cavity and seals with the dielectric cavity junction, and the other end is positioned at the heated medium of boiler body.The top of boiler body is provided with effuser, and the below is provided with return duct.Heat pipe is the vacuum tube that superconductive medium is housed in the pipe.
Its further scheme is that described electric heater unit is a plurality of, and vertical the setting.
For described dielectric cavity is sleeve pipe, and calandria is an electrical bar.Heat pipe is positioned at the top of sleeve pipe, and major part places heat medium.
It also can be the as a whole bottom that is positioned at boiler body of dielectric cavity, the dielectric cavity bottom is fixed with a plurality of calandrias, heat pipe all be seated on the upper baffle plate of dielectric cavity and with its sealing, the dielectric cavity upper baffle plate is fixed on the boiler body, and the effuser on the boiler body is arranged on the top of dielectric cavity upper baffle plate.Perhaps the dielectric cavity bottom that is positioned at boiler body is cavity independently, and effuser still is positioned at the below of boiler body.
Heated medium is generally aqueous medium.
With liquid heat-conducting medium heating in the dielectric cavity, be expanded to the top of heat pipe after the superconductive medium in the heat pipe is heated rapidly after the calandria energising, carry out after the heat exchange condensation rapidly with outside heated medium and fall back to the bottom and carry out above-mentioned heat exchange once more; Heat pipe passes to heated medium rapidly with the heat of liquid heat-conducting medium, because special electric heater unit is whole all to be immersed in the heated medium, dielectric cavity also is used as a calandria with the heat transferred heated medium simultaneously.Heated medium has been given in the almost all efficient conduction of heat energy that is converted into by electric energy like this.
Therefore, the beneficial effects of the utility model are rate of heat exchange height, quick heating, and compact conformation, pollution-free, high efficiency, noiselessness are easy for installation and maintenance.Simultaneously can also avoid the calandria dry combustion method, improve the functional reliability and the life-span of boiler.
