Abstract
The utility model discloses a support framework for heating elements of electric heaters. The utility model is arranged in an annular cavity chamber which is arranged between a metal outer shell and an insulated centre inner pipe with a heating element. The axial position of the annular cavity chamber is provided with two sections of the insulated support frameworks at least. The framework is fixedly connected with the inner wall of the outer shell and the outer wall of the inner pipe by three contact points, and then the inner pipe is centrally fixed on the center of an inner cavity of the outer shell. The radial position of the annular cavity chamber is connected with the inner wall of the outer shell or the outer wall of the inner pipe by three points, and the radial position of the annular cavity chamber is connected with the outer wall of the inner pipe or the inner wall of the outer shell by complete annular contact belts. The radical circumferential ring surface of the framework is provided with through holes which are uniformly arranged. The through holes and the rest of the annular cavity chamber are filled with insulating material.
Description
The utility model relates to the improvement of electric heater, specifically is a kind of heater element support frame of electric heater, and it belongs to the electric elements technical field.
Commercially available electric heater ubiquity two large problems: the one, safety issue, the 2nd, heat efficiency problem.Especially the water heater of immersion electric heating tube, because its electrical heating elements is directly water-immersed, thereby has the higher heat efficiency, but also there is certain danger in it, when service time is long slightly, with regard to easy generation electrothermal tube electric leakage and wound people's accident.This reason wherein has plenty of owing to manage off-center in the heater element central authorities of installing, and it is inhomogeneous to cause the electrothermal tube shell to be heated, so that influences the electric property of this pipe, even electrical breakdown takes place sometimes, causes the electric leakage accident to take place.
The purpose of this utility model provides a kind of heater element support frame of electric heater; this skeleton is safe in utilization; managed the support fixation effect in the central authorities to this device; and have insulation protection effect and a good heat transfer performance; it is firm that its structure is wanted; have certain intensity and help the raising of rate of heat transfer, prevent to use and transport in vibration.Task of the present utility model is finished by following technical scheme, developed a kind of heater element support frame of electric heater, it is installed in metal shell and insulation and is equipped with in the central authorities of heater element in the annular compartment between the pipe, on the axial location of this annular compartment, be provided with the support frame of at least two sections insulation, this skeleton connects solid on this outer casing inner wall and outer wall of inner tube at least with three contact points, thereby constituted the central settling position that should interior pipe be fixed on this shell inner cavity between two parties.
The heater element support frame of this electric heater, described support frame, its radial position place of this annular compartment or with this outer casing inner wall, or with this outer wall of inner tube, and connect with three contact points; And or with this in manage outer tube, or with this shell in manage, and connect with complete loop contacts band; And be filled with insulating material in all the other these annular compartments.
The heater element support frame of this electric heater, described support frame, its radial position place at this annular compartment all is to be connected with complete loop contacts band with this outer casing inner wall and this outer wall of inner tube, and on this skeleton circular radial border face of annular, be provided with through hole arranged in a uniform, all be filled with insulating material in this through hole with in all the other these annular compartments.
The heater element support frame of this electric heater, the insulating material of described support frame and filling all can be by magnesium oxide powder or/and mica powder (sheet) mix through adhesive, and compression molding curing is made.
The utility model has the advantages that: because the support frame of many contact points of difformity and structure is set in the inner chamber of metal shell, make be equipped with heater element should in pipe can be evenly and fully, transporting heat energy promptly, and can firmly stand the impact of various vibrations, prolonged the useful life of electric heating tube.Owing to this skeleton is to be made through adhesive mixing compression molding by the magnesium oxide material of insulation, thereby has a certain intensity, add contact point more than at least three and be connected in shell and the central authorities between the pipe, make this skeleton insulation, heat conduction, firm premium properties.
Embodiment accompanying drawings of the present utility model is as follows:
Fig. 1 is the mounting structure longitudinal section view (interior pipe three contact-types) of this heater element support frame.
Fig. 2 is the mounting structure longitudinal section view (outer tube three contact-types) of this heater element support frame.
Fig. 3 is the mounting structure longitudinal section view (the full contact-type of inner and outer pipes) of this heater element support frame.
Referring to Fig. 1---3, this support frame of making 2 is applied in the electric heater, it is made through the compression molding of adhesive mixing by magnesium oxide powder 3, it is installed in metal shell 1 and insulation is equipped with in the interior annular compartment of managing between 4 of central authorities of heater element, on the axial location of this annular compartment, be provided with the support frame 2 of at least two sections insulation, this skeleton 2 connects solid on this shell 1 inwall and interior pipe 4 outer walls at least with three contact points 6, pipe 4 is fixed on mesotropic settling position in this shell 1 between two parties in this thereby constituted.Should in can be supported with electrical heating wire 5 by this less skeleton 2 or insulating material such as magnesium oxide powder 3 in the pipe 4
The heater element support frame 2 of this electric heater, designed support frame 2, it is at radial position place of this annular compartment and this shell 1 inwall, or with this in pipe 4 outer walls, and connect with three contact points 6; And with this in pipe 4 outer walls, or with this shell 1 inwall, and connect with complete loop contacts band; Be filled with insulating material such as magnesium oxide powder 3 in all the other these annular compartments.
The heater element support frame 2 of this electric heater, designed support frame 2, its radial position place of this annular compartment and this shell 1 inwall with should in to manage 4 outer walls all be to be connected with complete loop contacts band, and on these skeleton 2 circular radial border faces of annular, be provided with through hole 7 arranged in a uniform, all be filled with insulating material such as magnesium oxide powder 3 in this through hole 7 with in all the other these annular compartments.
The heater element support frame of this electric heater, designed support frame and insulating material all are by magnesium oxide powder 3 or/and mica (powder) sheet mixes through adhesive, and compression molding curing is made.
