摘　　要：结合空调实际的使用环境开展热测试有利于暴露装备的热设计隐患,有助于提高空调的可靠性水平。基于空调实际使用中存在的散热问题,对某型空调开展了单一因素测试和考虑各种因素叠加作用的综合热测试。发现了产品的热设计薄弱环节,并采用热仿真的方法评估了设计优化后的效果,结果表明:关键元器件的温度均有所下降,最高下降接近5℃,优化效果显著,为今后产品的热设计提供了一定的参考。Thermal testing in conjunction with the actual use of the air conditioner can help to expose hidden problems in the thermal design of the equipment and help to improve the reliability of the air conditioner.A testing method is used to conduct single-factor tests and comprehensive thermal tests that take into account the superimposed effects of various factors on an air conditioner based on the thermal problems that exist in the actual use of the air conditioner.Weaknesses in the thermal design of the product are identified and the effect of the design optimisation are evaluated by using thermal simulation,and the results show that the temperatures of key components are reduced,and the highest drop is close to 5℃.The optimization effect is significant,which provides a certain reference for the thermal design of future products.
