Description
Technical field
It the utility model is related to automobile and fan hot device fan technology field, more particularly to a kind of speed change of radiator fans
Device.
Background technology
At present, radiator fans speed changer, typically it is made up of the assembling of resistance wire, ceramic body, quartz sand and shell, electricity
Resistance silk is placed in shell, and then quartz sand is filled in shell and plays insulating effect, shell two uses ceramic body sealing blocking again.
The speed changer of this structure has the following disadvantages：
1st, the assembling production process of speed changer is more, low production efficiency.
2nd, speed changer is working long hours after by high temperature, vibration, the easy loose or dislocation of ceramic body at shell both ends, and then causes
The quartz sand that insulate leaks, and produces wound resistive wire and touches together short-circuit, transmission failure and resistance wire contact housing defective insulation
The problems such as, speed changer structure reliability is relatively low.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of radiator fans speed changer, to solve existing skill
In art there is the low technical problem of low production efficiency, structural reliability in radiator fans speed changer.
The present embodiment radiator fans speed changer, including columned ceramic core, be spirally wound on ceramic core
Resistance wire and the epoxy resin layer being sealed in resistance wire covering on ceramic core.
Further, some grooves axially in parallel with ceramic core are provided with the outer surface of the ceramic core.
Further, the both ends of the ceramic core are additionally provided with the installation pin being connected with resistance wire.
The beneficial effects of the utility model：
1st, the utility model radiator fans speed changer, it uses ceramic core as insulator, resistance wire directly around
On ceramic core, manufacturing process is simple, and production efficiency is high.
2nd, the utility model radiator fans speed changer, fixed resistance silk, epoxy resin are sealed using epoxy resin
Resistance to elevated temperatures is good, and resistance wire is sealed by epoxy resin and covered, and resistance wire is fixed reliably, and speed changer in high temperature and shakes for a long time
Worked under the conditions of dynamic, be not in ceramic core resistance wire loosen, resistance wire short circuit and the problem of defective insulation.
Brief description of the drawings
Fig. 1 is the structural representation of the present embodiment radiator fans speed changer；
Fig. 2 is structural representation of the radiator fans speed changer after epoxy resin layer is removed in Fig. 1；
Fig. 3 is the end structure illustration of ceramic core.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As illustrated, the present embodiment radiator fans speed changer, including columned ceramic core 1, it is spirally wound on
Resistance wire 2 on ceramic core and the epoxy resin layer 3 being sealed in resistance wire covering on ceramic core.
The present embodiment radiator fans speed changer, it uses ceramic core to be directly wound on pottery as insulator, resistance wire
On porcelain core, manufacturing process is simple, and production efficiency is high.
And the present embodiment radiator fans speed changer, fixed resistance silk, epoxy resin are sealed using epoxy resin
Resistance to elevated temperatures is good, and resistance wire is sealed by epoxy resin and covered, and resistance wire is fixed reliably, and speed changer in high temperature and shakes for a long time
Worked under the conditions of dynamic, be not in ceramic core resistance wire loosen, resistance wire short circuit and the problem of defective insulation.
In the present embodiment, some grooves 4 axially in parallel with ceramic core, institute are provided with the outer surface of the ceramic core
The groove of setting can further improve the reliability that resistance wire is fixed with reinforced epoxy and the bonding strength of ceramic core.
In the present embodiment, the both ends of the ceramic core are additionally provided with the installation pin 5 being connected with resistance wire, in the present embodiment
Pin 5 is installed to be embedded in ceramic core, installation pin is fixed reliably, is not easy loose or dislocation.Certainly in different embodiments, installation is drawn
Pin can be also fixedly connected using other forms with ceramic core, can such as use mode connects for screw on ceramic core, or use anchor ear shape set
Hoop is first-class in ceramic core.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
