摘　　要：在高温条件下,变频空调器电流大且主板元器件的散热条件差,元器件的温升比较高。为了确保变频空调器的可靠性,通常采取控制压缩机降低运行频率来降低整机电流和主板温升,但这种方式导致了空调器性能的下降,影响了空调器的舒适性。为解决此问题,从元器件温升产生的原因进行了详细分析,提出了强化换热及优化元器件选型来降低元器件温升的解决方案,并通过理论分析和实验验证证明了解决方案的有效性。Under high temperature conditions,due to the large current of the whole machine and the poor heat dissipation conditions of main board components,the temperature rise of components is relatively high.In order to ensure the reliability of the whole machine,the compressor is usually controlled to operate at a lower frequency to reduce the current of the whole machine and the temperature rise of the main board.This way leads to the decline of the performance of the air conditioner and affects the comfort of users.In order to solve this problem,the causes of component temperature rise are analyzed in detail,and a solution to reduce componenttemperature rise by strengthening heat exchange and optimizing component selection is proposed.The effectiveness of the solution is proved by theoretical analysis and experimental verification.
