To achieve these goals, the utility model at first provides a kind of crude oil electric heater unit: be made up of spiral heat pipe, built-in controller, support structure, insulation casing.Described spiral heat pipe is made of the carbon fiber electrothermal layer of metal tube and insulating heat-conductive layer and this insulating heat-conductive laminar surface that is laid in.

In the technique scheme, described spiral heat pipe is that metal tube bends, with welding (or flange connection) metal tube of different length is connected to Len req, and the insulating heat-conductive layer has been done on the metal tube surface, temperature sensor is installed on metal tube simultaneously, and be connected with built-in controller, described built-in controller also is connected with electrode on the described carbon fiber electrothermal layer.

In the technique scheme, described carbon fiber electrothermal layer is that the carbon fiber electrically calandria of a plurality of grouping settings and the insulating of being done on carbon fiber electrothermal part are formed jointly; Each is organized carbon fiber electrothermal part and is successively set on side by side on the described spiral metal tube of doing the insulating heat-conductive layer, and carbon fiber electrothermal part is the electric heating body of being made by silk rope form carbon fiber or banded carbon fiber, and two ends are provided with the electrode that is used to connect feed cable.

Above-mentioned insulating heat-conductive layer can be by a kind of making wherein such as mica, pottery, quartz, basalt.

The upper and lower oil-in and oil-out and spiral heat pipe of being respectively equipped with in the outside of described casing joins for two sections, and is connected with inflow pipeline and flowline by screw thread or flange.

Crude oil electric heater unit of the present utility model has changed the deficiency in original technology.The dual-heated that the heating of its planar constant temperature evenly, reach decades service life, have radiation and a conduction because of the emission far ir ray is done usefulness, make the slow intensification of heated material and be unlikely to coking and collection sand, flow is big, properties of product are stable, can be in long-term stable operation under the complex conditions, energy conversion efficiency is 100%, utilization efficiency of heat energy is more than 98%, its power consumption only is about 70% of a traditional product, energy-saving effect is remarkable, is the regeneration product of positive displacement electric boiler or electric heater.Crude oil electric heater unit of the present utility model is made simple, with low cost, has extensive applicability.

The crude oil electric heater unit can be used for the heating of petrochemical industry industrial liquid, fluid, also can be used for water heater and heating boiler.As the water circulation heating of constant temperature heat supply, the central heating that can be made into small-sized suspension type immediate heating type pot-type boiler, swimming pool and sea-farming according to its principle, etc. large-sized boiler or heater.

Crude oil electric heater unit working voltage is the 36-380 volt; Shape, small-bore greatly etc. depends on the needs; Serviceability temperature is looked required heating material temperature tolerance decision, generally at 0-300 ℃.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.
