Abstract
The utility model discloses a vacuum heat tube type electric heater device. An electrothermal element is arranged in a heat tube type heat transmitter of which the inner is in vacuum state, and heat transfer working substances are arranged in the heat tube type heat transmitter of which the upper side is provided with a heat-transfer tube which can also be made into the spiral cantilever shape. The heat exchange portion of the vacuum heat tube type electric heater device is composed of a vacuum heat tube composed of the electrothermal element, the heat transfer working substances, the heat transmitter and the heat-transfer tube. The electrothermal element not contacts with heated liquid to avoid scale formation, and thus heat-transfer efficiency and heat exchange area are enhanced. The utility model has the advantages of long service life, energy saving and convenient operation. A user's maintenance cost is reduced, and the vacuum heat tube type electric heater device is especially suited to be used as an electric boiling-water heater.
Description
The utility model relates to a kind of electric heater unit, and particularly a kind of vacuum heat-pipe formula electric heater unit is the improvement to the common electrical heater.
Electric heater unit, for example electric water-boiling device has been widely used in life such as hotel, restaurant, hospital, school, office building with boiling water and working heat water environment, its have floor space little, be convenient to install, easy to use, easily realize advantages such as control automatically.Along with the development of electric utility and the raising of living standards of the people, the demand of this type of electric heater unit will enlarge day by day.The conventional electric heating device mostly is that heating directly is put in the heated liquid, as electric water-boiling device, heating contacts with water, because calcium ions and magnesium ions evaporates and fouling along with water temperature improves in the water, and hardy attached on the heating shell wall, be the non-conductor of heat because of dirt again, when dirt is tied certain thickness, then need timely removing, otherwise, heating very easily burns out, and user's maintenance capacity and maintenance cost are bigger, influences its use.
The purpose of this utility model be to provide a kind of heat transfer efficiency height, heat exchange area greatly, not easy burn-out and the electric heater unit being convenient to keep in repair, and overcome the deficiency of prior art.
The purpose of this utility model is to realize like this.The utility model utilizes the vacuum heat-pipe technology to combine with heating, make on the one hand heating not be heated liquid and contact, less scaling, in addition, utilize the isothermal characteristics characteristics of the fast and vacuum heat-pipe of vacuum heat-pipe heat transfer efficiency height, heat transfer rate, enlarge heat exchange area, like this because the expansion of heat exchange area, the dispersion of heating power makes fouling looser, very easily removes.Specifically, scheme of the present utility model is: in the conventional electric heating device, electrical heating elements is placed in the heat pipe-type heat transmitter chamber, this heat transmitter can be made patterns such as tubulose, be fastenedly connected with housing, the heat transmitter outer wall contacts with being heated liquid, and heat transmitter is vacuum state in the chamber, in adorn less scaling heat-transfer working medium.
In order to improve heat transfer area and efficient, heat transmitter is designed to tubulose, end sealing, the other end is fixed on the housing, and several heat-transfer pipes are set above, and heat-transfer pipe communicates with the heat transmitter chamber.
The heat pipe-type heat transmitter is designed to tubulose, spiral cantilevered heat-transfer pipe is set above, heat-transfer pipe one end is communicated with the heat transmitter inner chamber, the other end is the free arm state.Along with variation of temperature in the electric heater unit, helical form heat-transfer pipe curvature also changes and shakes, and therefore, the dirt of knot on heat-transfer pipe in time comes off, thereby makes vacuum heat-pipe keep heat exchange state preferably.
Below in conjunction with accompanying drawing the utility model is described further.
What accompanying drawing 1 provided is electric heater unit structural representation of the present utility model.
Fig. 2 is the structural representation of spiral cantilevered heat-transfer pipe electric heater unit.
With reference to Fig. 1, embodiment of the present utility model is an electric water-boiling device.
This electric water-boiling device external form is a tubular, heat pipe-type heat transmitter 3 is welded in the tube, be provided with heating 2 in the heat transmitter chamber, evenly distribute on the tubulose heat transmitter 3 and be provided with three heat-transfer pipes 5 and vertical welding, they communicate with heat transmitter 3, less scaling heat-transfer working medium 4 is housed in heat transmitter 3, and as demineralized water, heat transmitter is vacuum state in 3 chambeies.The vacuum heat-pipe that the heat exchange section of this electric water-boiling device is made up of heating 2, heat-transfer working medium 4 and heat transmitter 3 and heat-transfer pipe 5, heating 2 does not contact with the water 6 of desire heating, has therefore avoided the fouling of heating, has prolonged the life-span of heating.
The utility model not only can use as electric water-boiling device, also can be used for the electric heater unit to other liquid simultaneously.
In a word, the utility model has very big advantage than conventional art: because the heating non-scaling, selecting of the increase of heat exchange area and spiral heat pipe increased the service life of heating, reduced user's maintenance cost, saves energy, in addition, its range of application is big, and is rational in infrastructure, easy to use, be easy to promote.
