当流量及压差降低至一定程度时，共振腔还可能削弱换热；加热功率的提高会增加流体（水）的温度，流体的粘度会随着降低，这会减少对流体脉动的阻碍，使脉动衰减得更慢，而脉动幅度的增加会增强换热，故加热功率对有脉动的对流换热是有影响的；自振腔产生的流体脉动频率是自振腔固有频率或其整数倍,流体脉动频率过高或过低都不利于对流换热，存在一有利于强化换热的频率范围。 | | 3. | Because of the clamping capacitor and the interleaved structure , it has some good features compared with other flyback converters , such as : the topology is simple and can be realized easily ; the voltage spike of the power switch is availably restrained and without leakage - inductance energy loss ; the ripple of the input and output current is reduced , correspondingly , the volume and weight of the output and input filter is also significantly reduced
