Abstract
The utility model discloses an air heater which comprises a shell (2), a heating strap (4) and two binding posts (1). The shell (2) is a hollow rectangular plate, the heating strap (4) is positioned inside the shell (2) and is continuously serpentine, the two binding posts (1) are respectively connected with two ends of the heating strap (4) and mounted on two symmetric edges of the shell (2), ceramic insulating supports (5) are connected to inner sides of the other two symmetric edges of the shell (2), and bent portions of the heating strap (4) are clamped on the ceramic insulating supports (5). After the structure is adopted, the heating strap is clamped in grooves, which are provided with bosses, of the ceramic insulating supports, accordingly, the heating strap cannot deform basically due to the fact that the heating strap is bent when softened, fragments of the heating strap are hung on the ceramic insulating supports instead of directly dropping into a cylinder of an engine even if the heating strap is fused, the engine is guaranteed against being damaged, and the service life of the engine is prolonged.
Description
Technical field
The utility model relates to the auto parts machinery field, specifically is a kind of air heater that is used on the automobile engine intake tube.
Background technique
The inlet air heater is the electric heating equipment that gas stream is heated.In the air inlet pipeline of motor car engine; General because the DENG of big power; In engine start in winter difficulty relatively, usually air heater can be installed in inlet manifold, so that being provided fast, the hot air that gets into motor increases the compression ratio of motor.The air heater of existing technology comprises housing, wiring terminal, heating tape and insulating support, and housing is the rectangular plate of hollow, the shape of the S-shaped bending back and forth of heating tape, and the two ends of heating tape are connected with power supply through wiring terminal, and heating tape is arranged in the vacancy of housing.But; Shortcoming below the air heater of this structure exists: when being positioned at housing owing to heating tape; Except two ends with wiring terminal is fixedly connected, other places have no auxiliary connection immovable point, when long-time energising uses air heater that the defective regulator of alternator for vehicle is particularly arranged; Heating tape in the housing is owing to metal heat generating material under thermal expansion and the high temperature (heating tape is banded and very thin) will produce softening crooked the distortion; And the heating tape of S shape is arranged in parallel in the intermediate portion, because the space is limited and spacing is minimum, therefore; Adjacent two heating tapes can sticking hang together after bending deflection; Cause the phenomenon that produces big current fusing heating tape owing to the short circuit of circuit, the heating tape relic after the fusing will be in inlet manifold gets into the cylinder of motor when engine operation, thereby causes the catastrophe failure of motor.
The model utility content
The utility model technical problem to be solved is that a kind of air heater that prevents that heater band from dropping is provided.
For solving the problems of the technologies described above; The air heater that the utility model provides comprises housing, heating tape and wiring terminal, and described housing is the rectangular plate of hollow; Described heating tape is positioned at housing and is continuous a plurality of S shapes; Wiring terminal is two, be connected with the two ends of heating tape respectively, and wiring terminal is installed in the wherein both sides of one group of symmetry of housing; The inboard on the both sides of the other one group of symmetry of described housing all is connected with the ceramic insulation support, and the bending part of heating tape is connected on the ceramic insulation support.
The inboard on the both sides of described housing symmetry all is connected with the ceramic insulation support and is meant; Each inboard, limit on the both sides of housing symmetry all has the inside opening slot of opening; The two ends of said opening slot opening have the boss to the opening slot convex respectively, and described ceramic insulation support is positioned at opening slot and the formed cavity of boss thereof.
The bending part of described heating tape is connected on the ceramic insulation support and is meant; Have a plurality of containing grooves on the ceramic insulation support; The quantity of containing groove is identical with the bending part quantity of heating tape; A bending of the corresponding ccontaining heating tape of each containing groove, the bottom land of each containing groove has projection, and the bending of heating tape is connected on the projection of containing groove.
After adopting above structure, the utility model with compared with techniques is arranged, have the following advantages: when the defective regulator of long-time energising of heating tape or generator; Because the heating tape card hangs over the ceramic insulation support and has in the groove of boss, crooked and be out of shape when softening with regard to not being created in basically, even heater band has fused; Its relic can directly not fall down yet and get in the cylinder of motor; But hang on the ceramic insulation support, thereby guaranteed that motor can not be damaged, prolong the working life of motor.

Fig. 2 is the structural representation of link plate in the utility model air heater.
Wherein: 1, wiring terminal; 2, housing; 3, boss; 4, heating tape; 5, ceramic insulation support; 6, containing groove; 7, projection; 8, opening slot.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done explanation in further detail.
Structural representation by the utility model air heater illustrated in figures 1 and 2 can be known; It comprises housing 2, heating tape 4 and wiring terminal 1; Described housing 2 is the rectangular plate of hollow, and described heating tape 4 is positioned at housing 2 and is continuous a plurality of S shapes, and wiring terminal 1 is two; Two ends with heating tape 4 are connected respectively, and wiring terminal 1 is installed in the wherein both sides of one group of symmetry of housing 2.The inboard on the both sides of described housing 2 other one group of symmetry all is connected with ceramic insulation support 5, and the bending part of heating tape 4 is connected on the ceramic insulation support 5.
The inboard on the both sides of described housing 2 symmetries all is connected with ceramic insulation support 5 and is meant; Each inboard, limit on the both sides of housing 2 symmetries all has the inside opening slot of opening 8; The two ends of said opening slot 8 openings have the boss 3 to opening slot 8 convexes respectively, and described ceramic insulation support 5 is positioned at opening slot 8 and boss 3 formed cavitys thereof.
The bending part of described heating tape 4 is connected on the ceramic insulation support 5 and is meant; Have a plurality of containing grooves 6 on the ceramic insulation support 5; The quantity of containing groove 6 is identical with the bending part quantity of heating tape 4; A bending of each containing groove 6 corresponding ccontaining heating tape 4, the bottom land of each containing groove 6 has projection 7, and the bending of heating tape 4 is connected on the projection 7 of containing groove 6.
In the utility model, the bending part of heater band can be semicircle (shown in Fig. 1 and Fig. 2), and the shape of the containing groove on the corresponding ceramic insulation support also is semicircle; The bending part of heating tape also can be square, and the shape of the containing groove on the corresponding ceramic insulation support also is square; Or the like.These variations all fall within the protection domain of the utility model.
