The electric heating device provided by the utility model has the advantages that the working state is stable, the heat generation is even, the surface temperature is low, the reliability is high, and the electric heating device meets various requirements of consumers.

Description

A kind of electric heater

Technical field

The utility model relates to the electric heater technical field.

Background technology

Continuous development along with household electric appliances, household appliances are constantly weeded out the old and bring forth the new, the consumer is also more and more higher to the requirement of electric heater, require not only that electric heater capacity is big, volume is little, and require the shape of electric heater changeable, as the surface temperature that requires electric heater is low, the electric heating cost is low or the like, and the development in pluralism of household appliances has effectively promoted the development of electric heater technology.

The utility model content

The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, the electric heater that provide a kind of stable working state, generate heat evenly, surface temperature is low, high efficiency is high, cost is low.

The technical solution of the utility model is: a kind of electric heater comprises radiator, is located at the electrothermal tube in the radiator preformed hole and is set in the interior heating wire of electrothermal tube that wherein, described radiator is made up of the some blocks of heating panels of being located on the preformed hole outside.

Radiator is made up of four blocks of heating panels being located on the preformed hole outside, and its integral body is X type structure.

The preformed hole of radiator is a manhole, and it is positioned at the center of X type structure, and the aperture is 8mm.

The wall thickness of radiator is 1.5mm～3mm.

The outer wall pressing of the inwall of radiator preformed hole and electrothermal tube is in aggregates.

All handle with the punching press flange on the wing limit of being located on the spreader surface, and its flange angle is 30～45 °, and the flange height is 5mm～10mm.

In order to increase the heat-conducting effect of heating wire, the gap is filled with magnesia powder between electrothermal tube and the heating wire.

As the further improvement of this technical scheme, described radiator is an Aluminium Radiator.

The electric heater that the utility model provides utilizes the X type structure of its radiator and the electrothermal tube of heart preformed hole located therein, can make the heat radiation of radiator more even, thereby makes the heating of electric heater more even; And owing to be filled with magnesia powder in the electrothermal tube, make that the efficient of heat conduction is higher, thereby saved the energy that adstante febre uses, reduced the heating cost.This electric heater also utilizes its rational project organization, makes it also have advantages such as stable working state, surface temperature be low.

Fig. 3 is a heat sink side view of the present utility model;

Fig. 4 is the structural representation of electrothermal tube of the present utility model.

Embodiment

Below in conjunction with the drawings and the specific embodiments the utility model is further described.

As Fig. 1, Fig. 2 and shown in Figure 3, a kind of electric heater, comprise radiator 1, be located at the electrothermal tube 3 in the preformed hole 2 of radiator 1 and be set in heating wire 4 in the electrothermal tube 3, wherein, described radiator 1 is made up of the some blocks of heating panels of being located on the preformed hole outside.

Radiator 1 is made up of four blocks of heating panels being located on preformed hole 2 outsides, and its integral body is X type structure.The wall thickness m of radiator 1 can be 1.5mm～3mm.

As shown in Figure 4, the preformed hole 2 of radiator 1 is a manhole, and it is positioned at the center of X type structure, and the aperture is 8mm.

When electrothermal tube 3 was inserted in the preformed hole 2 of radiator 1, working pressure equipment was in aggregates with the outer wall pressing of the inwall of the preformed hole 2 of radiator 1 and electrothermal tube 3.

Is located at the wing limit 5 on radiator 1 surface and all uses the punching press flange, and its flange angle a is 30～45 ° that flange height h is 5mm～10mm.

In order to increase the heat-conducting effect of heating wire 4, the gap also is filled with magnesia powder 6 between electrothermal tube 3 and heating wire 4, to its fill out press the jail after, also electrothermal tube 3 is vacuumized.

As the further improvement of this technical scheme, described radiator 1 is an Aluminium Radiator.

During this electric heater energising work, heating wire 4 heating powers, by the magnesia powder 6 that is filled in the electrothermal tube 3 heat is conducted to electrothermal tube 3 surfaces, conduct to again on the radiator 1, spreader surface is carried out heat exchange by wing limit 5 and air, thereby heat is distributed in the air, reaches the effect that electric heater heats environment, and steady operation goes down always.
