Description
Technical field
It the utility model is related to electric-heating technology field, and in particular to a kind of high-performance composite heating film.
Background technology
Metal electric heating film is that metal foil is made into various resistive circuits to be clipped between two layers of insulation film piece.Tinsel
Can be stainless steel, copper or corronil.The small only several square centimeters of metal electric heating film component size, big is reachable several flat
Square rice.
Metal electric heating film is increasingly paid attention to by people, and is widely used, be because it have it is many traditional
The advantages of electric heating element and incomparable non-metal electric heating film institute, have as follows：
1) operating temperature is high, and element all can continuously work 300 DEG C；
2) service life is grown, and the life-span of metal electric heating film element is 10 times of traditional electric-heating-wire-heating element；
3) resistance to corrosion is strong, and metal level is fully sealed in a insulating layer, can be reasonably resistant to the corrosion of multi-chemical；
4) installation and easy-to-connect, wire can be fixed on element with the method for brazing or riveting, and element, which can be used, to be pasted
Or mechanical means is fixed on heated body.
However, there is following technical problem in the metal electric heating film that existing market is：Due to metal layer itself resistance wire sheet
The error of body size and the partial oxidation situation being likely to occur so that local electrical resistance is too high, so as to cause uneven feelings of generating heat
Condition occurs.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of high-performance composite heating film, not only
Make heating-up temperature more uniform, and under identical voltage, increase heating power, thermal conversion efficiency greatly improves.
The purpose of this utility model is achieved through the following technical solutions：A kind of high-performance composite heating film, including
First insulation high-temperature-resistant layer, metal restive layer, the second insulation high-temperature-resistant layer, hot boundary layer, the 3rd insulation high-temperature-resistant layer, described
One insulation high-temperature-resistant layer, metal restive layer, the second insulation high-temperature-resistant layer, hot boundary layer, the 3rd insulation high-temperature-resistant layer are from top to bottom
Setting is covered successively；
Preferably, the first insulation high-temperature-resistant layer, the second insulation high-temperature-resistant layer, the 3rd insulation high-temperature-resistant layer material can
For polyimides or PET；
Preferably, the material of the metal restive layer can be stainless steel, copper or corronil；
Preferably, the hot interlayer materials can be electrographite, graphene, CNT heat conduction membrane material, silica gel, silicon
Fat.
The beneficial effects of the utility model are：Hot boundary layer is introduced in common METAL HEATING PROCESS film so that metal produces
Heat rapidly can be homogenized by thermal interfacial material, make the more uniform purpose of heating-up temperature so as to reach, while can
Reach under same voltage, increase heating power, thermal conversion efficiency greatly improves.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model structure diagram；
In Fig. 1,1- the first insulation high-temperature-resistant layers, 2- metal restive layers, 3- the second insulation high-temperature-resistant layers, the hot boundary layers of 4-,
The insulation high-temperature-resistant layers of 5- the 3rd.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Embodiment：
As shown in figure 1, a kind of high-performance composite heating film, including the first insulation high-temperature-resistant layer 1, metal restive layer 2, second
Insulation high-temperature-resistant layer 3, hot boundary layer 4, the 3rd insulation high-temperature-resistant layer 5, the first insulation high-temperature-resistant layer 1, metal restive layer 2,
Second insulation high-temperature-resistant layer 3, hot boundary layer 4, the 3rd insulation high-temperature-resistant layer 5 cover setting successively from top to bottom.
In the present embodiment, the first insulation high-temperature-resistant layer, the second insulation high-temperature-resistant layer, the 3rd insulation high-temperature-resistant layer
Material is polyimides, and the material of the metal restive layer is copper, and the hot interlayer materials are electrographite.
The high-performance composite heating film of the present embodiment in the case of identical voltage 15.2V, is tested with common copper heating film
Parameter is contrasted, and correction data is shown in Table 1：
The high-performance composite heating film of table 1 and common copper heating film parameter comparison
| Parameter | Maximum temperature difference in heating surface | Heating power |
| High-performance composite heating film | 14℃ | 61.56W |
| Common copper heating film | 58℃ | 58.52W |
Shown by correction data, high-performance composite heating film and common copper heating film are high under identical voltage 15.2V
Maximum temperature difference is only 14 DEG C in performance composite heating film heating surface, hence it is evident that less than 44 DEG C common of copper heating film, high-performance is compound
Heating film heating power is 55.18W, and 3.04W is improved than common copper heating film.
The utility model introduces hot boundary layer in common METAL HEATING PROCESS film so that heat caused by metal can be rapid
Homogenized by thermal interfacial material, make the more uniform purpose of heating-up temperature so as to reach, while can reach under same voltage, increase
Big heating power, thermal conversion efficiency greatly improve.
Embodiment described above only expresses specific embodiment of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model patent scope.It should be pointed out that for the common of this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.
