die funktionsfähigkeit der heizleit

die funktionsfähigkeit der heizleiter wurde durch wiederholtes aufheizen mit stufenweise erhöhter Heizleistung überprüft. durch derartige aufheizversuche konnte die thermische Stabilität bis zu Temperaturen oberhalb 1000℃ nachgewiesen werden. Die Temperaturverteilung in einer ungedämmten heizplatte, wie sie in abb.4 dargestellt ist, ist nicht ohne weiteres homogen. Es ist zu erkennen, dass bei der gewählten Führung der Heizleiter die temperatur asymmetrisch verteilt ist und infolge der Wärmeverluste in den eckbereichen gegenüber dem zentrum um bis zu 33K abfällt. Eine ähnliche Tendenz ist auch für eine wärmegedämmte Heizplatte zu beobachten. Wird das experiment dagegen in einem ofen bei erhöhter Umgeebungstemperatur durchgeführt (abb. 5a), so werden die Temperaturunterschiede wegen der geringeren Wärmeverluste (d.h. der geringeren Heizleistung) wesentlich kleiner.

Functionality was the conductor through repeated heating up with gradually increased heat output. thermal stability could be established by such attempts of heating to temperatures above 1000℃. The temperature distribution in an uninsulated hot plate, as shown in fig 4, is not readily. It is to recognize that in the elected leadership of the heating cable temperature is asymmetric and falls as a result of heat losses in the corner areas opposite the Centre up to 33 k. A similar trend can be observed for a thermally insulated heating plate. The experiment, however, performed in an oven at high Umgeebungstemperatur (fig. 5a), the temperature differences due to the lower heat loss (i.e., the lower heat output) are much smaller.

the functional capacity of the grid lines was verified by repeated heat with gradually increased heating capacity. by such heating experiments, the thermal stability could be detected up to temperatures above 1000 ℃. The temperature distribution in a non-insulated hot plate, as shown in Fig.4, is not readily homogeneous. It can be seen that at the selected guide, the heat conductor, the temperature is distributed asymmetrically and falls due to the heat losses in the corner regions opposite the center by up to 33K. A similar trend can also be observed for a thermally insulated heating plate. When the experiment is on the other hand in an oven at elevated Umgeebungstemperatur performed (Fig. 5a), the temperature differences due to the lower heat losses (ie, the lower heating power) to be much smaller.

the function of the heizleiter was by repeated heating with gradually increased heat output was reviewed. such aufheizversuche the thermal stability up to temperatures above 1000℃ are demonstrated. the temperature distribution in a ungedämmten hot plate, as shown in figure 4 is not homogeneous. it can be seen that when the elected leadership of the heizleiter asymmetrically distributed temperature and as a result of the heat loss in the eckbereichen towards the centre to 33k falls off. a similar trend is also observed for a hot plate to heat. the experiment is carried out in an oven at elevated umgeebungstemperatur (figs. 5 (a)), the temperature differences due to lower heat losses (that is, the lower heat output) is much smaller.
