以自制高性能石墨基导电砂浆制作电热炕发热面,设计了北方火炕模型,通过Fluent数值模拟分析了电热炕的采暖性能,结果显示炕面温度分布均匀,致热效果好。经实测,在1kW快速升温档,电热炕迅速升温,其平均升温速率达0.75℃/min,在安全电压保温档时,电热炕炕体温度维持在25.7℃左右,环境温度也相对实验前升高2.7℃。
Self-made graphite-based conductive mortar was selected to make electrothermal kang heating plane and the model of kang has been designed in the north of China.Through fluent numerical simulation analyzed the heating performance of electrothermal kang,the result showed that the temperature of electrothermal kang＇s heating plane is evenly distributed,and heating effect is functional.Experimental result indicates that at 1kW rapid temperature increasing level,the temperature of electrothermal kang increased rapidly,and the average increasing rate is 0.75℃/min,while at the safe-voltage temperature insulating level,the temperature of kang body remains at around 25.7℃,and the environment temperature increased 2.7℃ compared with that before the experiment.
