首发时间:2013-10-31
Abstract:This paper presents a micro induction heater based on the principle of induction heating. The liquid contact with the micro heater core directly and heated by the eddy current effect. The heating effect of the micro heater is simulated with the software of COMSOL. The simulation results indicate that the temperature of the micro heater core can reach to 540K in 0.9s while the current is 0.7A and the power frequency is 200 kHz. The relations between the heating effect and the micro induction heater's parameters such as the current, the AC power frequency and the coil's parameters are studied in the simulation respectively. The prototype of the micro heater has been fabricated and the experimental test has carried with the micro heater. The experiments indicated that the micro heater can generate thermal bubble in 0.9s while the 0.6A high frequency current passes through the heater coil. The micro induction heater can be applied to a variety of thermal bubble devices, such as micro injector, micro switch and micro pump.

一种微型感应热发泡加热器的设计与实现
摘要:基于电磁感应加热原理,本文设计了一种微型感应加热器。该加热器加热芯与被加热液体直接接触,利用电涡流的热效应来对液体进行加热。采用有限元方法对加热器的加热效果进行了仿真分析,结果表明在电流为0.7A,加热时间0.9s时,加热芯的温度可以达到540K,且分布均匀。仿真研究了频率、电流、线圈匝数和直径等参数对微加热器加热效果的影响,并绘制了影响关系曲线图。制作了微型加热器样件,并进行了热发泡的实验,实验表明:当通入电流为0.6A时,所制样件可以在0.9s内生成气泡。微感应加热器加热性能稳定、效率高,可用广泛应用于微喷嘴、微驱动器和微泵等热泡式驱动器件中。
