The disadvantage of the presented device is the design complexity and system control.

Known electric heater, comprising a housing, inside which is placed a capsule filled with 95% of the volume of the heat storage substance with the phase transition in the area of operating temperatures, and electric heating elements connected to a power source, as teploakkumuliruyushchikh the substance use of eutectic mixture of chloride salts of sodium and calcium. In this design on the capsule relief valve connected with the air volume of the capsule, around which is placed one or more electric heaters (RF Patent No. 2103618 F24H 7/02, F24D 15/02, 1998).

The disadvantage of this device is the design complexity and the need to use protective elements, which may themselves be the cause of an emergency in case of contact with molten salts as a safety valve when the cold start device reset pressure will become impossible. Such a device requires the introduction of additional regulatory systems to maintain rational temperature regime and eliminate overheating of heating Elements.

The invention aims to reduce energy losses and increase the efficiency of regulation of the heat output.

The solution of this problem is achieved by the fact that in electricalautomotive heater, comprising a housing, a heat storage substance and a heater connected to the power source, the heater is made of interacting with a movable electrode conductive layer containing carbon nanomaterial, above which is located thermal storage dielectric layer.

The movable electrode is made in the form of a cone, mounted on a spring loaded piston, equipped with the om hollow rod with an adjusting nut.

Between the conductive layer containing carbon nanomaterial, and thermal storage dielectric layer is placed a layer of silicone.

The body is enclosed in a jacket provided with a nozzle inlet and outlet protection and insulation.

Perform heater cooperating with a movable electrode conductive layer containing carbon nanomaterial, above which is located thermal storage dielectric layer, reduces energy losses and improving the efficiency of regulation of the heating power due to the use of ohmic properties of the conductive layer and simplify and improve the reliability of the regulatory process heating power. This provides increased functionality of the device, since the heating capacity depends on the contact surface of a movable electrode and a conductive layer that is provided with the conical shape of the movable electrode. When reaching the set temperature automatically allocating a movable electrode forces volume expansion conductive and heat-retaining materials and re-enable when they are cooled to a predetermined temperature.

Performing a rolling electrode in the form of a cone, mounted on a spring loaded piston, fitted flooring is a rod with an adjusting nut, allows for easy application of the device by eliminating complex regulatory device that improves the efficiency of regulation of the heating power

The space between the conductive layer containing carbon nanomaterial, and thermal storage dielectric layer is a layer of silicone provides the ease of use of the device is still operational at any position.

Conclusion corps shirt, equipped with a nozzle inlet and outlet protection and insulation, reduces energy loss and increase ease of use - as for the various tasks it is enough to connect to the nozzles supplying environment.

Electrochemically heater provides adaptive power with such fluids as air and water, with the possibility of accumulation of heat and maintain the temperature rational mode.

Electrochemically heater (figure 1) contains a finned housing 1 in which is placed a conductive layer 2, for example, carbon nanomaterial, mixed with paraffin, impermeable elastic layer 3 of silicon bulk layer with thermal storage dielectric material 4 with a phase transition, for example paraffin, the electrode 5 made in the form of a cone, whose base is fixed to the piston 6 through the washer 7, made of dielectric, pin 8, is placed in the channel of the hollow shaft 9 and enclosed in a tube 10 of a dielectric material (fiberglass, PTFE f-4 etc). Between the housing 1 and the piston rod 9 is placed elastic element 11 made in the form of conical springs. The housing 1 is enclosed in a casing 12 with pipe supply environment 13, the pipe outlet environment 14 and the insulation 15. The upper part of the housing 1 provided with a sleeve 16, in which is mounted a rod 9 and interoperates with adjusting nut 17 mounted on the threaded end of the rod 9. The power supply to the heater is supplied through the electrical contact 18 on the end of the stud 8 and grounded the e 19 of the housing 1.

Electrochemically heater works as follows. When applying an electric voltage to the electrical contact 18 a voltage insulated from the piston 6 washer 7, the electrode 5 is supplied to pin 8, isolated from the rod 9 and the piston 6 of the insulating tube 10. The electric current flows in the volume between the electrode 5 and the conductive layer 2 on the housing 1 with the ground 19, resulting in a volumetric heat generation. The heat is transferred into the environment through the fins of the housing wall 1 and the upper heat-retaining layers 4. Heat is removed from elektroteploenergiju heater by filing environment (air or water) through pipes inlet and outlet of the medium 13 and 14 in the cavity between the housing 1 and the casing 12, enclosed in thermal insulation 15. When the temperature of the phase transition in the conductive layer 2 and layer with thermal storage dielectric material 4 is increase that accompanied the rise of the piston 6 and the moving electrode 5 beyond the impermeable layer 3 in the dielectric layers 4, which leads to the unlocking of the supply chain. In this case stops power from an external source until, until the cooling layers 2 and 4, causing a decrease in the volume of the layers 2 and 4, and the elastic element 11 will return electrode 5 in the switching-mode power is Badawi layer 2. This will cause a re-current flow and heat dissipation. With the adjusting nut 17 rod 9 can move relative to the sleeve 16, this changes the height of immersion of the electrode 5 in the conductive layer 2, which allows you to change the output device.

Comparative tests elektroteploenergiju heater with traditional means of electric heating (heating Elements and nichrome coils) showed a decrease in energy loss by 30% when transferring heat to such fluids as air and water. This is due to the high teplokomunenergo and the ability to change power in increments of 2 W and a wide adjustment range from 10 W to 20 kW.
