Answer coil heats.
Water heating is carried out using hot-water boiler, not only consumes a large amount of non-renewable energy resources, it is super that there is also boiler superpressures
The larger security risk of temperature explosion.When electrothermal tube heats, resistance wire not only generates heat but also shines, and the thermal efficiency is lower, and dry
When burning, the serious accidents such as fusing and booster are generated, cause machine internal component to damage, or even fire can be caused.Utilize electromagnetism sense
Equipment surface temperature is too high when answering coil heats, when dry combustion method will lead to the damage of machine internal component, or even can cause fire, and
High-frequency current flows through magnetic induction loop and generates strong change electromagnetic induction heating to iron pipe part, generates compared with strong electromagnetic radiation, if people locates for a long time
This compared in strong electromagnetic radiation environment, damage can be generated to the body of people.
Utility model content
For this purpose, the utility model embodiment provides a kind of electric hot water tank, to solve in the prior art since use can not be again
Raw energy sources for heating, water power Direct Contact Heating or electromagnetic heating are inefficient with thermal transition caused by strong electromagnetic radiation, pacify
Full blast nearly larger problem.
To achieve the goals above, the embodiments of the present invention provides the following technical solutions:
In the first aspect of the embodiments of the present invention, provide a kind of electric hot water tank, including shell, liner,

Thirdly, the setting upper cover and the lower head, when needing to carry out checking maintenance to the electric hot water tank, by institute
It states upper cover and the lower head is removed, to improve checking maintenance efficiency
Four, vacuum-pumping tube is set, and when normal work, the filling weight of heat medium is the 1/2~2/ of the liner capacity
3, and the liner is vacuumized, it is at negative pressure state, to reduce the boiling point of heat medium, enhancing heat medium molecule fortune
Dynamic activity, and then help to improve heat exchanger effectiveness.Meanwhile under exsiccosis, the pressure balance of heat medium is broken, institute
The pressure for stating liner is restored rapidly to normal pressure, the heat medium elevation of boiling point, to play the buffer protection function to equipment.
Five, media discharge pipe is set, in favor of regularly replacing heat medium, prevents heat medium for a long time using change
Matter guarantees heating effect, convenient for carrying out repair and maintenance to equipment.
Six, fixed bracket is set, the electric heater is fixed, prevents electric heater from being knocked over, equipment is caused to damage
Bad or safety accident.
Seven, the main heat exchange pipe is corrugated tube, further increases heat exchange area, improves heat exchange efficiency.
Eight, the main heat exchange pipe is using the alloy material Jing Guo surface oxidation treatment, and inner surface is coated with insulation and receives
Rice anti oxidation layer, and then the ability of the resistant to pressure and anticorrosion leak of the main heat exchange pipe is improved, it reduces since the master changes
Electric fault caused by after heat pipe leak.
