The equipment is simple in structure, low in manufacturing cost, secure and reliable in operation and simple in maintenance and repair.
Description
The utility model relates to a kind of device that heated medium is heated with resistive film, refers to especially be separated by with insulating material, and resistive film heats the metal heat transfer body, thereby heats the heater of heated medium again.
Current China living standards of the people progressively improve, demand to all kinds of household electrical appliance heightens, in order to satisfy state's human needs, household electrical appliance are of a great variety on the market, especially the electric heater kind is also very various, but not outer is to adopt resistance wire, heating techniques such as resistive film, recently adopt the resistive film heat protocol little by little to be widely adopted on the market, this is that the heat efficiency is higher because its technology is simple, power savings is also fine, to this class heater adopt enamel and pottery as the heat transfer matrix of resistive film on the market more, use practice to show that enamel peels off easily, pottery breaks easily, its the possibility of result can cause heater charged, bring potential safety hazard, this specification requirement of safety is the most important specification requirements of household electrical appliance, as seen to the resistive film heater commonly used safety and energy-conservation aspect suddenly wait to improve.
The purpose of this utility model is to provide a kind of heated medium to separate with electricity according to above-mentioned, higher with structural strength, rigidity, heat transfer efficiency is good, the metal material of mature production technology is as thermal conductor, be aided with relevant insulating material and insulation material composition one resistive film heater efficiently, can constitute all kinds of heaters as required.
The purpose of this utility model is achieved through the following technical solutions:
A kind of resistive film heater, mainly by metal heat transfer body (1), heat-conducting glue (2), insulation material layer (3), resistive film (4), electric contact (5), insulation material (6) is formed, and wherein insulation material layer (3) one sides are coated with resistive film (4), insulation material layer (3) opposite side glueds joint with heat-conducting glue (2) and metal heat transfer body (1) one side, outside at resistive film (4) coated with insulation material (6), connect electricity by electric contact (5) in addition, naked of metal heat transfer body (1) contacts with heated medium (7).
The utlity model has following advantage and effect:
1, the utility model adopts heated medium and electric separated structures form, puts with insulating material the safe and reliable civil electric appliance standards for safe use that reaches between resistive film and the metal heat transfer body.
2, the utility model adopts metal heat transfer body, structural strength good rigidity, heat transfer efficiency height.
3, the utility model is simple in structure, low cost of manufacture, and maintenance and repair are simple and easy.
The drawing of accompanying drawing is described as follows:
Fig. 1 is that the utility model resistive film heater structure is formed schematic diagram
Fig. 2 is used for tubular electric resistance film heater general structure schematic diagram for the utility model embodiment
Among the figure: 1, metal heat transfer body 2, heat-conducting glue 3, insulation material layer 4, resistive film 5, electric contact
6, insulation material 7, heated medium 8, metal heat transfer pipe 9, insulating material pipe
Be described further below in conjunction with drawings and Examples:
Illustrate by Fig. 1, the utility model resistive film heater structure is formed, mainly by metal heat transfer body 1, heat-conducting glue 2, insulation material layer 3, resistive film 4, electric contact 5, insulation material 6 is formed, wherein insulation material layer 3 one sides are coated with resistive film 4, insulation material layer 3 opposite sides glued joint with heat-conducting glue 2 and metal heat transfer body 1 one side,, connect by electric contact 5 in addition coated with insulation material 6 in resistive film 4 outsides, 1 naked of metal heat transfer body contacts with heated medium 7, this heater heat transfer direction is shown in the black direction of arrow of Fig. 1, and the utility model can be used for making water heater, electric thermos flask or make chafing dish heater etc.
Illustrate by Fig. 2, the utility model embodiment is used for tubular electric resistance film heater general structure, and wherein metal heat transfer pipe 8 can adopt stainless steel tube, its non-corrosive, the structural strength good rigidity, good heat-transfer does not have any specific (special) requirements on assembly technology, can adopt other metal tubes certainly yet, aluminium-alloy pipe for example, copper pipe, titanium alloy tube or the like, this can decide according to physics, the chemical characteristic of need of work and heated medium.The heated medium that present embodiment flows in metal heat transfer pipe 8 is a water, for example flows by the white direction of arrow (but also rightabout).Be coated with heat-conducting glue 2 in metal heat transfer pipe 8 outsides, be used for glueing joint the insulating material pipe 9 that puts, the heat-conducting glue 2 wherein and the material of insulating material pipe 9 should adopt the material of good heat conduction effect, heat-conducting silicone grease-50 heat-conducting glue for example, the high-boron-silicon glass insulating material pipe coated with resistive film 4, is made electric contact 5 in insulating material pipe 9 outsides on resistive film 4, attached on the resistive film 4, add the copper cap with the silver slurry in order to connecing.In the resistive film outside coated with insulation material 6, the high-effect compound insulating material of IC type (coating type) insulation material for example, form insulation film and prevent that more effectively heat energy is to exterior conductive, simultaneously increased fail safe again, can make the centralized heat energy of heater conduct heat so that heated medium 7 water are heated like this to direction shown in the black arrow.This embodiment shows the version of electricity separation, reaches safe and reliable instructions for use, owing to adopted metal heat transfer pipe 8, enamel and the possible phenomenon of peeling off or breaking of pottery can not take place, has eliminated potential safety hazard.Insulating material pipe 9, insulation material 6 form efficient concentrating water are carried out the heat conduction heating, therefore can reach the purpose of energy savings again efficiently.
In addition, the utility model can not use heat-conducting glue 2 in some concrete structure, and is air layer.In some concrete structure,, but should guarantee its safety again because the characteristics of heat transfer of resistive film also can not covered heat-insulation layer.
