摘　　要：针对嵌入式冰箱压缩机仓散热效果不佳的问题,采用数值模拟与试验结合的方法对其散热进行研究。模拟了嵌入式冰箱压缩机仓的散热过程,结果显示冰箱背部气流未经过充分散热再次进入到压缩机仓形成短路气流,且由于橱柜的影响进入压缩机仓内的总气流相较于自由状态下减少了51.78%;针对散热效果差的原因提出了3种不同适用场景的优化方案,并对各方案在通风量、能耗、制冷性能方面进行对比研究。结果表明,3种优化方案均能改善散热效果,但各有优劣,优化方案的总风量比原嵌入方案分别提高了3.9%,75.3%,55.3%;在32℃和16℃的环境温度下,3种优化方案的能耗相较于原嵌入方案分别降低了6.50%和3.90%,23.03%和25.07%,17.70%和17.50%。研究结果为不同适用场景下的嵌入式冰箱压缩机仓散热优化提供了解决思路和参考。In view of the problem of poor heat dissipation effect of embedded refrigerator compressor warehouse,a combination of numerical simulation and experiment was used to study its heat dissipation.Firstly,the heat dissipation process of the embedded refrigerator compressor warehouse was simulated.The results show that the airflow on the back of the refrigerator enters the compressor warehouse again without sufficient heat dissipation to form a short-circuit airflow,and the total airflow entering the compressor warehouse due to the influence of the cabinet is reduced by 51.78% compared with the free state.Then,three optimization schemes for different applicable scenarios were proposed for the cause of poor heat dissipation effect,and the ventilation,energy consumption and refrigeration performance of each scheme were compared and studied.The results show that the three optimization schemes can improve the heat dissipation effect,but each has its own advantages and disadvantages.The total air volume of the optimization scheme is 3.9%,75.3% and 55.3% higher than that of the original embedding scheme,respectively.The experimental results show that at the ambient temperature of 32℃ and 16℃,the energy consumption of the optimized scheme is reduced by 6.50% and 3.90%,23.03% and 25.07%,17.70% and 17.50%,respectively,compared with the original embedding scheme.The research results provide different solutions and references for the heat dissipation optimization of embedded refrigerator compressor warehouse in applicable scenarios.
