Abstract
The utility model discloses a kind of electric heating tube of water heater, comprise the heat-generating pipe that two heat-generating pipe parallel, spaced-apart are arranged, this heat-generating pipe is U-shaped, and is coated with cast aluminium protective layer outside heat-generating pipe.U-tube tube side is two-tube-pass, and flow process is longer, and flow velocity is higher, and heat transfer property is better, and bearing capacity is strong; Be coated with cast aluminium protective layer outside heat-generating pipe, utilize aluminium feature rapidly of conducting heat to avoid on heat-generating pipe and gather amount of heat, avoid that temperature is too high burns out heat-generating pipe, not only can protect heat-generating pipe when dry combustion method but also useful life of heat-generating pipe can be extended; The chemical property of aluminium is sprinkled than ironwork, can prevent the chloride ion corrosion stainless steel inner container in running water.
Description
Technical field
The utility model relates to a kind of electric heating tube of water heater, particularly a kind ofly increases the service life and protects the electric heating tube of water heater of inner bag.
Background technology
The electrical bar that the electric heater sold in the market adopts is easy to when dry combustion method damage; And bad owing to hotting plate water quality used, cause shorten the useful life of electrical bar, simultaneously due in running water containing clorox, the time chloride ion corrosion stainless steel inner container that produces of heating.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of electric heating tube of water heater.
The utility model solves the technical scheme that its technical problem adopts:
A kind of electric heating tube of water heater, comprise at least one heat-generating pipe, this heat-generating pipe is U-shaped, and is coated with cast aluminium protective layer outside heat-generating pipe.
Preferably, described heat-generating pipe has two, and two heat-generating pipe parallel, spaced-apart are arranged.
Further, it also comprises the splicing ear being arranged on heat-generating pipe end, is provided with insulator between described heat-generating pipe and splicing ear.
In addition, described splicing ear is provided with stator.
Further, it also comprises the temperature probing tube be arranged between two parallel heat-generating pipes.
The beneficial effects of the utility model are:
The heating tube of the utility model electric heating tube of water heater is U-tube, and U-tube tube side is two-tube-pass, and flow process is longer, and flow velocity is higher, and heat transfer property is better, and bearing capacity is strong; Be coated with cast aluminium protective layer outside heat-generating pipe, utilize aluminium feature rapidly of conducting heat to avoid on heat-generating pipe and gather amount of heat, avoid that temperature is too high burns out heat-generating pipe, not only can protect heat-generating pipe when dry combustion method but also useful life of heat-generating pipe can be extended; The chemical property of aluminium is sprinkled than ironwork, can prevent the chloride ion corrosion stainless steel inner container in running water.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is assembly drawing of the present utility model;
Fig. 2 is explosive view of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model discloses a kind of electric heating tube of water heater, comprise two parallel, spaced-apart and arrange heat-generating pipe 1, this heat-generating pipe 1 is U-shaped, and two single u-shaped heat-generating pipe 1 parallel, spaced-apart can ensure the patency of current; Be coated with cast aluminium protective layer 3 outside heat-generating pipe 1, this cast aluminium protective layer 3 can increase the heat conductivility of heat-generating pipe 1, and heat-generating pipe 1 can also be protected not easily by dry combustion method, thus extends the useful life of heat-generating pipe.
As shown in the figure, the electric heating tube of water heater of the technical program also comprises the supporting splicing ear 2 being arranged on heat-generating pipe 1 end, splicing ear 2 is provided with described in stator 4 and is provided with insulator 5 between heat-generating pipe 1 and splicing ear 2, to ensure that the junction of heat pipe and splicing ear can not be leaked electricity to stator 4, in this specific embodiment, stator 4 adopts stainless steel to make, stator 4 makes splicing ear 2 can be securely fixed on electric heater, avoids coupling part and damages by external force.
In addition, the electric heating tube of water heater of the technical program also comprises the temperature probing tube 6 be arranged between two parallel heat-generating pipes 1, for detecting the temperature residing for heat-generating pipe in real time, controls for temperature.
Above-mentionedly just preferred embodiments more of the present utility model are illustrated and described; but execution mode of the present utility model is not restricted to the described embodiments; as long as it reaches technique effect of the present utility model with substantially identical means, all protection range of the present utility model should be belonged to.
