Description
Technical field
The utility model relates to automotive seating art field, more particularly, relates to a kind of conductive heating film and seat thin film heater.
Background technology
Along with the fast development of modern automobile industry technology, electric heating base chair system is as a kind of important vehicle comfort system, and widely driver and crew welcome.It has more direct, rapid, energy-conservation seat heating heating effect than mounted air conditioner system, progressively becomes the basic function requirement of cold region vehicle in winter, obtains the accreditation in market more and more sooner.
In the application of current existing automotive seat electric heating system, what often adopt is to be arranged the heated web/non-woven pad made by resistive heater or resistance lamination coating.The fan of fixed form or stitching seat surface sleeve that this type of heating pad adopts local strip to paste bearing pads usually combines with seat.
The heating pad of this type of heated web/non-woven due to the impact that heating uniformity is poor, temperature rise controls the factors such as difficulty, gradually by application market is queried and lose the market influence.This type of heated web/non-woven pad adopts complicated production technology to complete usually, its higher application cost also widely market denounced.
In recent years, a kind of emerging printed conductor type seat thin film heater technical study is arisen at the historic moment.It is characterized in that having conductive gold layer or the silver layer of pectination symmetry electrode patterning, synthesize the thermal barrier coatings such as carbon serous coat with the graphitec carbon serous coat covered or graphite+organic filler and carry out stacked printing and synthesize, achieve more uniform film heating film.The conductive heating film of this kind of seat thin film heater adopts the techniques such as such as screen printing, achieves more easy production Technology, more effectively reduces productive costs, achieve more uniform seat heating function.Meanwhile, conductive gold layer or silver layer synthesize carbon serous coat etc. with graphitec carbon serous coat or graphite+organic filler and are printed on the high-quality plastic film base materials such as such as mylar, polycarbonate film or Kapton, and temperature booster achieves more flexible applicability.
Usually, the distance that between the pectination symmetry electrode of conductive heating film inside, interval is fixing, the thermal barrier coatings such as the graphitec carbon serous coat of covering or graphite+organic filler synthesis carbon serous coat cover between pectination symmetry electrode, play the effect of resistive UNICOM.Under on load voltage, electric current, from one end of pectination symmetry electrode, flows to the other end of pectination symmetry electrode through thermal barrier coatings.Now, thermal barrier coatings produces electro heat effect.The conductive heating film of the thin film heater of complete automotive seat is inner, is made up of the pectination symmetry electrode group with thermal barrier coatings of several arrangements.
Due to spacing distance fixing between the inner pectination symmetry electrode of conductive heating film, the thermal barrier coatings between each pectination symmetry electrode is made to present homogeneous heat resistance characteristic.Namely the heating distribution of conductive heating film inside is homogeneous.
But, due to the application at automotive seat, consider that buman body type and ergonomics take feature, usually need the heating-up temperature difference characteristic of considering to carry out some key area.Such as, the local enhancement of human upper leg is heated, and can be increased the suitable sense of temperature of shank and foot by blood circulation of human body.Now, the temperature booster technology of the fixing pectination symmetry electrode spacing of traditional sense is just difficult to meet the demands.And adopting the pectination symmetry electrode of different spacing, temperature regulates difficulty higher on the one hand, and on the other hand, the pattern of conductive heating film is attractive in appearance to be affected, and application client can be raised an objection.
Therefore, how under the prerequisite of pectination symmetry electrode not adopting different spacing, solve the problem that heating film is difficult to local temperature adjustment, become the technical matters that those skilled in the art are urgently to be resolved hurrily.
