摘　　要：本文为空调变频控制器散热设计了一种新型的热管翅片式换热器,通过COMSOL仿真和样机实验对比了该换热器与常规的铝板翅片式换热器的换热效果。结果表明:当室外温度为35℃、53℃和60℃时,采用热管翅片式换热器散热可使元器件温度降低1.8~4.2℃。当室外温度为53℃和60℃时,采用铝板翅片式换热器的空调的最大制冷量分别衰减到额定制冷量的63%和21%,而采用热管翅片式换热器的空调的最大制冷量分别为额定制冷量的100%和62%,且元器件的温度降低了11.2~11.9℃。当室外温度为46℃时,采用热管翅片式换热器的空调的速冷时间缩短了66.7%;当室外温度为46℃和52℃时,该空调的降温时间分别缩短了82.6%和89.7%,房间平均温度最低值分别降低了3.9℃和4.6℃。A new type of heat pipe finned heat exchanger was designed for the heat dissipation of the inverter controller.The heat exchange effects of a conventional aluminum plate-fin heat exchanger and the heat pipe finned heat exchanger was evaluated and compared through numerical simulations by COMSOL and experiments of air conditioner prototypes.The results show that when the outdoor temperatures are 35 ℃,53 ℃ and 60 ℃,the component temperatures using the heat pipe finned heat exchanger for heat dissipation are 1.8~4.2 ℃ lower.When the outdoor temperature is 53 ℃ and 60 ℃,the maximum cooling capacity of the air conditioner with an aluminum plate-fin heat exchanger is reduced to 63% and 21% of the rated cooling capacity,while the maximum cooling capacity of the air conditioner with a heat pipe fin heat exchanger is 100% and 62% of the rated cooling capacity,respectively and the temperature of the components is 11.2~11.9 ℃ lower.When the outdoor temperature is 46 ℃,the air conditioner with the heat pipe finned heat exchanger reduces the quick cooling time by 66.7%.When the outdoor temperature is 46 ℃and 52 ℃,the cooling time of the air conditioner is reduced by 82.6% and 89.7%,respectively;while the lowest value of the average room temperature is 3.9 ℃and 4.6 ℃ lower,respectively.
