电机冷却是保障线性压缩机高可靠性运行的关键。建立了基于实验运行参数及温度的直线振荡电机损耗模型,分析了电机铜损、铁心损耗和涡流损耗随温度的变化趋势,并耦合线性压缩机流场三维模型,对电机线圈和永磁体的温度分布特性进行了变工况分析。结果表明:在相同的进气温度下,质量流量每提升0.2 g/s,电机温度降低4~20 ℃,且温度分布方差降低0.5~1.2;相同质量流量下,进气温度每降低5 ℃,电机温度降低4~6 ℃。永磁体的最大温差为0.6 g/s质量流量工况下的7.3 ℃和1.4 g/s质量流量工况下的6.9 ℃。优化后的进气结构使电机温度分布方差减小了5.521,最高温度下降了4.1 ℃,最大温差下降了4.55 ℃。
Motor cooling is critical for ensuring the high reliability of linear compressors. This study established a linear oscillating motor loss model based on experimental operating parameters and temperatures. The trends of the copper loss
iron core loss
and eddy current loss of the motor with temperature were analyzed
coupled with a three-dimensional flow field model of the linear compressor to analyze the temperature distribution characteristics of the motor coils and permanent magnets under different operating conditions. The research results demonstrated that
for every 0.2 g/s increase in mass flow rate
the motor temperature can be reduced by 4-20 ℃
and the variance of temperature distribution decreases by 0.5-1.2 under the same intake temperature. Furthermore
for every 5 ℃ decrease in intake temperature
the motor temperature decreases by 4-6 ℃ under the same mass flow rate. The maximum temperature difference of the permanent magnet was 7.3 ℃ at a mass flow rate of 0.6 g/s and 6.9 ℃ at a mass flow rate of 1.4 g/s. The optimized intake structure reduced the variance of motor temperature distribution by 5.521
the highest temperature decreased by 4.1 ℃
and the maximum temperature difference decreased by 4.55 ℃.
