Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
Be illustrated in figure 1 carbon fiber electric heater unit of the present utility model, it comprises shell 10, intermediate layer 30, carbon fiber heating paper 40, temperature control modules and input protection unit 50.Wherein, temperature control modules comprises a temperature sensor 21, and this temperature sensor 21 can be arranged on outside or the inner side of shell 10 neatly.Preferably, temperature sensor 21 is arranged on the inner side of shell 10, which saves space, and the temperature detected is more accurate.Shell 10 can be made up of stainless steel material or other metal material, preferably, adopts magnadure as the shell 10 of carbon fiber electric heater unit of the present utility model.Intermediate layer 30 is arranged between the inner side of shell 10 and carbon fiber heating paper 40.The Main Function in intermediate layer 30 makes carbon fiber heating paper 40 and shell 10 keep insulation, protects carbon fiber heating paper 40 simultaneously.One end of input protection unit 50 connects electric main AC, and its other end connects temperature control modules.Have between temperature control modules with carbon fiber heating paper 40 and be electrically connected, temperature control modules controls the heating of carbon fiber heating paper 40 according to the temperature that temperature sensor 21 feeds back, thus realizes the intelligent temperature control to carbon fiber electric heater unit.
This carbon fiber heating paper 40 is ceramic fibre enhancement mode carbon fiber heating paper, and it comprises sandwich construction, and skin is pulp layer 41, and internal layer is the heating layer 42 that heating paper is formed.Heating paper is the heating paper be made up of ceramic fibre, ceramic powders, carbon fiber and paper pulp.Such as, ground floor is paper pulp, the second layer be heating layer 42, the third layer that heating paper is formed is paper pulp.
Application paper pulp instead of polymer carry out disperse carbon fibers as base material, and the degree that paper pulp softens when temperature raises is very low, and therefore carbon fiber sheets heater can use at higher temperatures.In addition, the paper be made up of paper pulp has higher intensity than the paper be made up of carbon fiber.Preferably, carbon fiber being longitudinally dispersed in paper pulp with alignment along heating paper that diameter is 10 ~ 70 μm, length is 2 ~ 25mm is chosen.The ceramic fibre of high heat conductance and ceramic powders are disperseed together with carbon fiber manufacture ceramic fibre enhancement mode carbon fiber heating paper.Like this, the heat produced in the region that carbon fiber content is high can be transmitted to the low low-temperature region of carbon fiber content by the ceramic fibre of high heat conductance and ceramic powders, thus makes the uniformity of temperature profile of whole carbon fiber heating paper 40.Therefore, the temperature sensor 21 be arranged on inside shell 10 just can accurately feed back the temperature of carbon fiber heating paper, thus improves the temperature control precision for carbon fiber electric heater unit.Compared to the firing equipment using carbon fiber quartz heating tube, use carbon fiber heating paper 40 can reduce the volume of heater, and when customizing according to embody rule situation, cost also greatly reduce.
According to a preferred implementation, aforesaid intermediate layer 30 is made up of glass-fiber-fabric and insulation board, and insulation board is by coated for carbon fiber heating paper 40 and be fixed on centre, and the skin of insulation board is packed tightly by glass-fiber-fabric.Carbon fiber heating paper 40 and shell 10 insulate by insulation board and glass-fiber-fabric, ensure that fail safe during use.Serve effect that is fixing and protection carbon fiber heating paper 40 simultaneously.Intermediate layer 30 can also be made up of the polymeric layer insulated, and this polymeric layer has resistant to elevated temperatures characteristic.Polymeric layer is laminated on the surface of carbon fiber heating paper 40, make carbon fiber heating paper 40 operationally with external insulation, simultaneously also protect carbon fiber heating paper 40.When electric current flows through carbon fiber heating paper 40, heat can be produced.When applying voltage, the regional temperature that the temperature in the region that carbon fiber content is high is lower than carbon fiber content is high a lot.Electric insulation is carried out on two surfaces polymeric layer being laminated to heating paper, and when elevating the temperature when applying voltage to heating paper, the polymeric layer on this lamination and heating paper can expand.It is more that the polymeric layer being laminated to the high region of carbon fiber content expands, but its expansion can be subject to the suppression of the polymeric layer in the lower region of the low temperature of neighbouring carbon fiber content.This can form compression stress to the polymeric layer being laminated to the high region of carbon fiber content, thus polymeric layer may be caused to come off from heating paper, may cause delaminated area that dielectric breakdown occurs.Carbon fiber electric heater unit of the present utility model is owing to have employed ceramic fibre enhancement mode carbon fiber heating paper, and carbon fiber heating paper 40 operationally generates heat evenly, improves the stability of heater.Employing polymeric layer carries out insulating to carbon fiber heating paper 40 and can better adapt to the architectural characteristic of carbon fiber heating paper, and volume is reduced further.
As shown in Figure 2, the temperature control modules of carbon fiber electric heater unit also comprises micro-control unit MCU, temperature controller 22 and control panel 23.The input of micro-control unit MCU connects temperature sensor 21 and control panel 23, and the output of micro-control unit MCU connects temperature controller 22.The temperature data that micro-control unit MCU feeds back according to temperature sensor 21 and user generate the adjustment data outputting to temperature controller 22 via the control data that control panel 23 inputs, these adjustment data are digital signal.Temperature controller 22 is built-in with digital to analog converter, in order to adjustment data are converted to analog signal, thus adjusts the operating state of carbon fiber heating paper 40.Temperature sensor 21 is infrared temperature sensor, the quick temperature sensor of thermoelectricity or IC temperature sensor, preferably, adopts infrared temperature sensor.Because carbon fiber heating paper 40 is mainly heated object by thermal radiation, radiant energy transmits in the form of an electromagnetic wave, and its wave-length coverage is in far infrared band region.Infrared temperature sensor utilizes thermal effect of radiation, can feed back the variations in temperature that carbon fiber heating device causes more accurately, thus improve temperature controlled precision.
Micro-control unit MCU is preset with the rational sampling period, and according to the actual size of carbon fiber electric heater unit and the difference of concrete usage space, the scope in this sampling period is 0.5min ~ 10min.Aforementioned sample periodic regime avoids the power consumption and low stability that frequent adjustment carbon fiber heating device heat condition causes.Rational sampling adjustment cycle is beneficial to the useful life of reducing energy consumption, improving carbon fiber electric heater unit.User according to actual conditions, can also regulate the sampling period by control panel 23, to reach the result of use of the most comfortable.
The temperature controller 22 of temperature control modules is arranged between micro-control unit MCU and carbon fiber heating paper 40, it act as the adjustment data exported according to micro-control unit MCU and carrys out the size of current of control flow check through carbon fiber heating paper 40, thus controls the heat condition of carbon fiber heating paper 40.Concrete, two ends, the vertical or horizontal edge carbon element type high temp conductive adhesive electrode of carbon fiber heating paper 40, also saves space like this while ensureing electrical connection good between carbon fiber heating paper 40 and electrode.
