Abstract
The utility model relates to an electric heater unit which is especially suitable for a long-term high temperature heating field. At present, an electric heater unit generally employs magnesium oxide as insulation and heat conduction filling materials. Since the insulating performance of the magnesium oxide is relatively poor, excessive magnesium oxide filling material affects heat conduction, further reduces thermal efficiency, and shortens the service lifetime of the electric heater unit. The utility model discloses an electric heater unit comprising a heating element, an insulating layer, a housing, a leading out conductor and a seal head, wherein the insulating layer employs hexagonal boron nitride as insulation and heat conduction filling materials, the heating element is a bostrychoid resistance wire, the housing is tubular, and the leading out conductor is a metallic rod or a metallic wire. An electric heater unit which is long in service lifetime, high in heat efficiency and small in housing dimension is provided in the utility model for users who needs long-term high temperature environment.
Description
Technical field
The utility model relates to a kind of electric heater unit, is specially adapted to long term high temperature and heats the field.
Background technology
Electric-heating technology is widely used in the many aspects that people produce, manage and live, different demands according to use occasion, the variforms such as that electric heater unit has is tubular, tabular, round, but its basic structure is electric heating element, insulating barrier, shell, conductor introduction and end socket etc.In the factor that the quality of electric calorifie installation is impacted, the quality of material accounts for very major reason, and the making raw material of choose reasonable electric calorifie installation are the prerequisites that guarantees the electric calorifie installation quality; The life-span of electric calorifie installation is except outside the Pass having with the electric heating element quality, and is also relevant with the quality of insulating heat-conductive filler.
Hexagonal boron nitride is inert material, have good electrical insulating property, thermal conductivity and chemical resistance, stable chemical nature is inertia to all motlten metal chemistry, and has very high moisture-proof, this material temperature under an atmospheric pressure reaches 2500 ℃ the distillation phenomenon just occurs, and has high-temperature stability.
Need to provide for a long time hot environment in some specific occasions or device, the electric heater unit that uses at present generally adopts magnesium oxide as the insulating heat-conductive filler, because magnesian insulation property are relatively relatively poor, just must adopt more magnesium oxide to fill in the electric calorifie installation manufacture process, to satisfy its insulating requirements, and too much magnesium hydroxide filler has affected electric heating element to the conduction of the heat on electric calorifie installation surface, and not only the heat efficiency reduces, and has also had a strong impact on the useful life of electric heater unit.This just makes this type of occasion or device easily occur to stop transport because of the electric heater unit fault.
Summary of the invention
The purpose of this utility model provides a kind of adaptation energy long-time running and efficient electric heater unit under hot environment.
The technical solution of the utility model is a kind of electric heater unit, is comprised of electric heating element, insulating barrier, shell, conductor introduction and end socket etc.; It is characterized in that being: described insulating barrier uses hexagonal boron nitride as the insulating heat-conductive filler; Described electric heating element is spiral resistance wire; Described shell is tubular, describedly tubularly can be processed into as required U-shaped, undaform, spiral type, straight rod type; Circle, ellipse, rectangle, triangle etc. can be processed into as required in the cross section of described tubular shell; Described conductor introduction is metal bar or plain conductor.Can as required several these devices be combined into the boundling electric heater in actual applications.
The beneficial effects of the utility model are: the user of hot environment is provided for a long time for needs, a kind of have long-life, high thermal effect, electric heater unit that shell sizes is less are provided.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment
[0009] in accompanying drawing, 1. conductor introduction, 2. end socket, 3. shell, 4. insulating barrier, 5. electric heating element.
Embodiment
With reference to accompanying drawing 1, the utility model embodiment is that heating wire is inner at the installation metal tube, the centre has insulating barrier (being the hexagonal boron nitride material) isolated, the inner of two metal bars is connected and extends to outside metal tube with heating wire two ends respectively, uses joint filling material to make end socket and metal tube two ends are sealed gets final product.When external power source through metal bar when the resistance wire, the heat of generation spreads to metal tube surface by hexagonal boron nitride, then is delivered in heated object or air and goes, and reaches the purpose of heating.
The production method of the utility model embodiment: in the process of making electric heating tube, must adopt filler to divide used outside insulated with heating wire and outer tube, the thermal energy conduction that simultaneously heating wire is produced also is called " filling out powder " to the electrothermal tube surface.As long as complete " filling out powder " technique with hexagonal boron nitride as filler.
In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation form, all drop on the protection range of the utility model requirement.
Claims (7)
