加热扳 meaning in English

hot plate

So these circuits can be simplified . due to the power output of the electromagnetism vortex water heater has direct relation to the interval between the vortex board and the excitation loop plane
由于热水器的热功率输出跟涡流加热扳与励磁线圈平面之间的距离有直接的关系，距离越小则输出功率越大。
The smaller interval is the larger power output is . so in order to be the largest power output , the structure should be as small as possible . as far as the instantaneous heating electromagnetism vortex water heater is concerned , the power which the excitation device outputs is too small , so we adopt two e
又由于对于即热型电磁涡流热器来说，单个励磁装置输出的功率过小，达不到加热的目的，因而木电磁涡流热水器采用两套励磁装置，进行双面加热，每块涡流加热扳的两表面均有水流过，即整体上采用双面加热，四面过流的结构方式。
