Abstract
The utility model relates to a novel electric heater, which is suitable for high-temperature heating of media in a low-voltage small-current environment. Heating tubes are connected with helical fins and are inserted into a container, connecting parts between the heating tubes and the helical fins are welded at high frequency, fluid can advance forwards along a helical structure without being pushed to flow under high pressure as in the traditional electric heater, and thus, the voltage in a working environment is reduced; and electric heating wires are arranged from a dense wire layout to a sparse wire layout according to the flow direction of the media, electric heating elements in an equitemperature field ensure that internal temperature is uniform without local hot spots, the helical fins on the outer wall of the heating tube are good for heat transfer and have the advantage of reducing the surface temperature of the electric heater and ensuring that the novel electric heater can still work normally in a high-temperature environment.
Description
Technical field:
The utility model relates to a kind of electric heater, particularly a kind of novel electric heater that is suitable in low pressure, low discharge environment medium is carried out heat.
Background technology:
Run in the environment of low pressure, low discharge the occasion of gas medium being carried out heat in process electric heater field through regular meeting, traditional electric heater is because complex structure, and pressure is bigger, can't satisfy the occasion of low pressure heating; And high temperature alarm usually takes place in traditional electric heater, and heated gas is fully heated, and do not reach the requirement of outlet temperature, and in order to reach temperature requirement, electric heater can be because overtemperature shortens its service life.
The utility model content:
The purpose of the utility model is to provide a kind of novel electric heater that is suitable in low pressure, low discharge environment medium is carried out heat.
To achieve these goals, the utility model proposes following technical scheme realization:
A kind of novel electric heater is made up of terminal box, process flange, heating tube, container, helical fin, heat generating component; Heating tube links to each other with terminal box, and terminal box is provided with cable access, fills the nitrogen mouth; Heating tube and the welding of process flange; Insert heat generating component in the heating tube; Heat generating component draws rod, terminals, fiber thermal insulation board, over-temperature sensor by ceramic supporting element, heating wire, cold junction and forms; Cold junction draws an excellent end and is provided with terminals; Cold junction draws rod and passes the fiber thermal insulation board and connect heating wire at the other end, heating wire according to the flow direction of medium from close silk to rare layout; Be provided with ceramic supporting element, over-temperature sensor in the heating tube; It is characterized in that: heating tube is connected with helical fin and inserts in the container.
Described heating tube and helical fin connecting portion adopt high-frequency welding.
The soluble technical problem of the utility model is:
(1) heating tube and helical fin adopt high-frequency welding to connect as one structure, and fluid can not need conventional electric heater mesohigh propulsive medium to flow along the helical structure advances, has reduced the pressure in the working environment.
(2) heating wire according to the flow direction of medium from close silk to rare layout; The heating of equitemperature field makes internal temperature even, hot localised points can not occur, and the helical fin of heating tube outer wall is beneficial to heat transfer; Reduced the surface temperature of electric heater, also can operate as normal in hot environment.
Description of drawings:
Fig. 1 is the utility model patent structure figure;
Fig. 2 is the utility model patent heating tube cutaway view.
The specific embodiment:
As shown in the figure, a kind of novel electric heater is made up of terminal box 1, process flange 2, heating tube 3, container 4, helical fin 5, heat generating component; Heating tube 3 links to each other with terminal box 1, and terminal box 1 is provided with cable access 6, fills nitrogen mouth 7, and nitrogen filled protection can increase the service life, and is applicable to explosion-proof occasion; Heating tube 3 and 2 welding of process flange, heating tube 3 adopts thick walled steel tube, can make the corrosion resistance of heating tube 3 stronger; Insert heat generating component in the heating tube 3; Heat generating component by ceramic supporting element 8, heating wire 9, cold junction draw rod 10, terminals 11, fiber thermal insulation board 12, over-temperature sensor 13 are formed; Cold junction draws rod 10 1 ends and is provided with terminals 11, and cold junction draws rod 10 and passes fiber thermal insulation board 12 and connect heating wire 9 at the other end, heating wire 9 according to the flow direction of medium from close silk to rare layout; It is more reasonable to make that heating tube 3 interior temperature fields distribute, and is provided with ceramic supporting element 8, over-temperature sensor 13 in the heating tube 3; Heating tube 3 is connected with helical fin 5 and inserts in the container 4; Heating tube 3 adopts high-frequency welding with helical fin 5 connecting portions, and fluid can not need conventional electric heater mesohigh propulsive medium to flow along the helical structure advances; Reduced the pressure in the working environment; The helical fin of heating tube outer wall is beneficial to heat transfer, has reduced the surface temperature of electric heater, also can operate as normal in hot environment; Change heating tube 3 like need, can process flange 2 be extracted out, do not need the emptying medium, the scene replacing heating element heater of can loosing core is convenient for changing.
This patent is suitable in low pressure, low discharge environment, medium being carried out heat, has great promotional value.
Claims (2)
