Abstract
The utility model discloses a heating device of an electric water heater, which comprises electric heating pipes and water containers. The electric heating pipes take the shape of a straight rod and are laid out in parallel; from one end to the other end of each electric heating pipe, the water container is a metal pipe helically winding on the surface of the electric heating pipe; and both ends of the metal pipe are a water inlet and a water outlet respectively. The electric heating pipes of the heating device are separated with water, so that the heating device not only avoids scale at the surface of the electric heating pipes but also has good thermal conductivity. In addition, the heating device prevents electric leakage caused by direct contact between water and electric heating pipesand has safe use and high thermal efficiency.
Description
Technical field
The utility model relates to a kind of electric heater assembly, particularly a kind of heating apparatus of electric water heater.
Background technology
Along with the development of society, electric heater substitutes the main flow that gas heater becomes water heater just gradually.Existing heating apparatus of electric water heater generally is made up of electric heating tube and water receptacle, and electric heating tube is placed in the water of water receptacle and heats, and surface and water by electric heating tube carry out heat exchange, thereby realize the heating of water.Yet the heating apparatus of electric water heater of this structure in use electric heating tube adheres to incrustation scale easily, causes capacity of heat transmission to descend, even causes electric heating tube to break, and also have the potential safety hazard of electric leakage, and heat exchange area is little, and the thermal efficiency is low.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of heating apparatus of electric water heater, has good capacity of heat transmission, and is safe in utilization and the thermal efficiency is high.
In order to solve the problems of the technologies described above, a kind of heating apparatus of electric water heater of the present utility model, comprise electric heating tube and water receptacle, described electric heating tube is direct rod shape and arranges side by side, described water receptacle is that an end to the other end from electric heating tube is spirally wound on its surperficial metal tube, and the two ends of metal tube are respectively water inlet and delivery port.
As improvement of the technical scheme, be filled with the metal heat-conducting body between described electric heating tube and the water receptacle.
Be further improvement in the technical proposal, described metal heat-conducting body is a metallic aluminium.
The beneficial effects of the utility model are: this heating apparatus of electric water heater is owing to adopt said structure, electric heating tube and moisture from, both avoided forming incrustation scale on the surface of electric heating tube, has good capacity of heat transmission, avoided water directly contact appearance easily again and leaked electricity with electric heating tube, safe in utilization and the thermal efficiency is high.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is an internal structure schematic diagram of the present utility model;
Fig. 2 is a surface structure schematic diagram of the present utility model;
Fig. 3 is a sectional structure schematic diagram of the present utility model.
The specific embodiment
With reference to Fig. 1, a kind of heating apparatus of electric water heater of the present utility model, comprise electric heating tube 1 and water receptacle 2, described electric heating tube 1 is direct rod shape and arranges side by side, described water receptacle 2 is that an end to the other end from electric heating tube 1 is spirally wound on its surperficial metal tube, and the two ends of metal tube are respectively water inlet 21 and delivery port 22.Water is heated by electric heating tube 1 in the metal tube of flowing through, the electric heating tube 1 of this heating apparatus of electric water heater and moisture from, both avoided forming incrustation scale on the surface of electric heating tube, has good capacity of heat transmission, avoided water directly contact appearance easily again and leaked electricity with electric heating tube, safe in utilization and the thermal efficiency is high.On the other hand, because electric heating tube 1 is arranged in parallel separately, wherein any electric heating tube breaks down and can independently change, and need not to change whole heater, helps economizing on resources.
With reference to Fig. 2 and Fig. 3,, be filled with metal heat-conducting body 3 between described electric heating tube 1 and the water receptacle 2 in order to increase the uniformity that adds thermal effect and guarantee to heat of electric heating tube to water receptacle.Described metal heat-conducting body 3 is heat conductivility good metal, and wherein best is metallic aluminium.
Claims (3)
1. heating apparatus of electric water heater, comprise electric heating tube (1) and water receptacle (2), it is characterized in that described electric heating tube (1) is direct rod shape and arranges side by side, described water receptacle (2) is that an end to the other end from electric heating tube (1) is spirally wound on its surperficial metal tube, and the two ends of metal tube are respectively water inlet (21) and delivery port (22).
2. heating apparatus of electric water heater according to claim 1 is characterized in that being filled with metal heat-conducting body (3) between described electric heating tube (1) and the water receptacle (2).
3. heating apparatus of electric water heater according to claim 2 is characterized in that described metal heat-conducting body (3) is a metallic aluminium.
