Below with reference to Fig. 1-Fig. 2, the electric heater 100 according to the embodiment of the present invention is described.
According to the electric heater 100 of the embodiment of the present invention, as shown in Figure 1, comprising: shell 3, inner bag 1 and composite heat-insulating layer 2.Inner bag 1 is located in shell 3, and the space limited between inner bag 1 and shell 3 is space of foaming, and composite heat-insulating layer 2 is filled in foaming space, and namely composite heat-insulating layer 2 is filled between shell 3 and inner bag 1.
Particularly, as shown in Figure 1, electric heater 100 also comprises electric-controlled box 8, and electric-controlled box 8 is located in foaming space.Electric heater 100 also comprises magnesium rod 4, outlet pipe 5, water inlet pipe 6 and heater 7, one end of magnesium rod 4, water inlet pipe 6, outlet pipe 5 and heater 7 extend in inner bag 1 respectively, the other end of magnesium rod 4 stretches in foaming space through inner bag 1, stretch out after the other end of water inlet pipe 6 and outlet pipe 5 is each passed through inner bag 1, composite heat-insulating layer 2, shell 3, the other end of heater 7 is electrically connected with electric-controlled box 8.Wherein, water inlet pipe 6 and outlet pipe 5 all adopt the pipe fitting with anti-electricity wall function.It should be noted that, the structure, principle etc. of the operation principle of magnesium rod 4, water inlet pipe 6, outlet pipe 5 and heater 7 and the pipe fitting with anti-electricity wall function are prior art, no longer specifically describe here.
With reference to Fig. 2, composite heat-insulating layer 2 comprises heat-insulation layer 21 and air-locked confining bed 22, heat-insulation layer 21 is located on the outer surface of inner bag 1, confining bed 22 is located on the outer surface of heat-insulation layer 21, and namely confining bed 22 is distributed in the periphery of heat-insulation layer 21, thus, the extraneous air of electric heater 100 not easily enters heat-insulation layer 21 and takes away heat, for single heat-insulation layer 21, the heat-insulating property of composite heat-insulating layer 2 is higher, decreases the heat losses of electric heater 100.
In addition, in some instances, heat-insulation layer 21 is formed by foaming agent foam, and abscess inside is filled with the very low foaming agent gas of thermal conductivity factor, and the foaming agent gas of abscess inside makes heat-insulation layer 21 have excellent insulation, heat-proof quality.Due to electric heater 100, in use temperature is higher, and is often in the environment of variations in temperature, and local may exceed the boiling point of the inner blowing agent of abscess.But in prior art, the rate of closed hole of expanded material does not reach 100%, and in part abscess, foaming agent gas can volatilize, the heat-insulating property of heat-insulation layer 21 is caused to decay.Therefore, the setting of air-locked confining bed 22 can close heat-insulation layer 21, foaming agent gas is avoided to pass confining bed 22 and overflow, thus ensure that insulation, the heat-proof quality of heat-insulation layer 21, when electric heater 100 is used in Long-Time Service or the environment in variations in temperature, insulation, the heat-proof quality decay of heat-insulation layer 21 are slow, reduce the energy consumption of electric heater 100, and extend the service life of electric heater 100.And electric heater 100 is machining and putting into after storehouse deposits a period of time, its heat-insulating property is intact, improves the efficiency probability of acceptance of spot check of electric heater 100, decreases producer's loss.

This example has fully utilized polyurethane heat insulation material and closed material two kinds of insulation materials advantage separately, owing to adding the closed material of one deck densification at the outer surface of polyurethane heat insulation material, thus can effectively prevent the volatilization of blowing agent in polyurethane abscess from overflowing, solve the high temperature attenuation problem that in electric heater 100, polyurethane heat insulation material exists well, the decay of the heat-insulating property of polyurethane foam under reduction high temperature, increase the durability of its heat-insulating property, thus it is guaranteed that the heat-insulating property of polyurethane insulation coating can be made to continue, guarantee that electric heater 100 still has excellent heat-insulating property and higher efficiency grade after a longer time of use.
According to the electric heater 100 of the embodiment of the present invention, by arranging the air-locked confining bed 22 of one deck on the outer surface of heat-insulation layer 21, integral heat insulation, the heat-proof quality of electric heater 100 are good, and the heat-insulating property durability of heat-insulation layer 21 is high, the coefficient of energy dissipation of electric heater 100 is low, when using under Long-Time Service or hot environment, the heat insulation effect of electric heater 100 is decayed slowly, long service life.
In certain embodiments, confining bed 22 is sealing paint layer, and that is, sealing paint brushing defines the confining bed 22 of one deck densification at the outer surface of heat-insulation layer 21, confining bed 22 is provided with air impermeability, ensure that heat-insulation layer 21 and ambient atmos cannot circulate.Use sealing paint brushing on the outer surface of heat-insulation layer 21, its technique is simple, exploitativeness is high, and heat-insulation layer 21 is adjustable at the brushing thickness at diverse location place, such as heat-insulation layer 21 is corresponding to the seam crossing of shell 3, the thickness of confining bed 22 can suitably increase, and can need the thickness adjusting confining bed 22 easily according to insulation.
Particularly, sealing paint layer is thermal insulation coatings layer, and namely confining bed 22 is formed by the thermal insulation coatings brushing in sealing paint, thus, further increases the insulation of composite heat-insulating layer 2, heat-proof quality, improves the efficiency of electric heater 100.
Alternatively, the thickness of thermal insulation coatings layer is 0.01-0.20mm, and thus, can ensure that confining bed 22 has the air impermeability of satisfying the demand, and the coating consumption of confining bed 22 is few, cost is lower.
Advantageously, sealing paint layer covers on whole outer surfaces of heat-insulation layer 21, thus ensures that whole outer surfaces of heat-insulation layer 21 are all closed layer 22 and block, and insulation, the heat-proof quality of heat-insulation layer 21 are better.Certainly, the coating position of confining bed 22 also can be set in the present invention according to actual needs, not do concrete restriction here.
In a preferred embodiment, sealing paint is the thermal insulation coatings of excellent thermal insulation performance, the thickness of confining bed 22 is 0.01-0.20mm, thus, heat-insulation layer 21 can be closed by confining bed 22 well completely, good seal, prevent the volatilization of foaming agent gas in its inner cell from overflowing, also there is good heat-insulating property simultaneously, the heat-insulating property of electric heater 100 can be improved further.
