Abstract
The utility model relates to a ceramic electrothermal element comprising a ceramic base board, electrodes and a heating body, wherein, the electrodes are connected with both ends of the heating body. The utility model is characterized in that the heating body is printed on the ceramic base board; the ceramic electrothermal element also comprises a ceramic cover board covered on the ceramic base board to cover the heating body; the ceramic base board and the ceramic cover board are fused together by sintering. Because the ceramic base board and the ceramic cover board are fused together by sintering, the ceramic base board and the ceramic cover board have a same thermal expansion coefficient; the heating body is insulated from outside. The utility model has the advantages of simple manufacturing technique, good tightness performance, good insulation performance, strong heating and impacting resistance and long service life, and prevents the heating body from oxidizing in work.
Description
Technical field
The utility model relates to a kind of ceramic electric heating element.
Background technology
At present, domestic widespread usage ceramic electric heating element comprises two ceramic substrates, on a substrate, print heater, after another substrate will print the heater covering, the middle low-temperature glaze that adopts is bonded and sealed, shortcoming is that sealing is poor, easy oxidation during heater work, the poor insulativity under the wet condition; Glaze is different with the ceramic matrix thermal coefficient of expansion, and it is poor to bear thermal shock, so the life-span is short.
Summary of the invention
The purpose of this utility model is: a kind of ceramic electric heating element is provided, and not only manufacturing process is simple for it, good seal performance, oxidation in the time of preventing going up heater work, good insulation preformance, and also the tolerance thermal shock is strong, long service life.
The utility model is achieved in that a kind of ceramic electric heating element comprises ceramic substrate, electrode, heater, electrode is connected with the two ends of heater, its special character is: heater is printed on the ceramic substrate, also comprise a ceramic cover plate, ceramic cover plate covers on ceramic substrate heater is covered, and ceramic substrate and ceramic cover plate sintering fuse together.
The utility model ceramic heating element, because heater is printed on the ceramic substrate, ceramic cover plate covers heater on ceramic substrate, ceramic substrate and ceramic cover plate sintering fuse together, and ceramic substrate is identical with the ceramic cover plate thermal coefficient of expansion, heater and external insulation, so not only manufacturing process is simple, good seal performance, oxidation in the time of preventing going up heater work, good insulation preformance, and the tolerance thermal shock is strong, long service life.
Description of drawings
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is Figure 1A-A view.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of ceramic electric heating element comprises ceramic substrate 1, electrode 3, heater 2, two electrodes 3 are connected with the two ends of heater 2, heater 2 is on ceramic substrate 2, also comprise a ceramic cover plate 4, ceramic cover plate 4 covers on ceramic substrate 1 heater 2 is covered, and ceramic substrate 1 fuses together with ceramic cover plate 4 sintering.
The production method of the utility model ceramic electric heating element, on the living embryo of the ceramic base of a slice flow casting molding, use the screen-printed metal resistance slurry to form heater 2, the ceramic cap embryotega is covered on the ceramic base embryo and with heater 2, superimposed under certain temperature and pressure, through certain binder removal, firing process ceramic base embryo, heater 2, the ceramic cap embryo burns altogether, the ceramic base embryo, the ceramic cap embryo forms ceramic substrate 1 respectively, ceramic cover plate 4 and ceramic substrate 1, ceramic cover plate 4 fuses together, then produce at last and comprise ceramic substrate 1, heater 2, the ceramic electric heating element of ceramic cover plate 4, two electrodes 3 weld with heater 2 two ends respectively, promptly produce the finished product ceramic heating element.
