Abstract: In order to solve the high-temperature heat dissipation problem of inverter power devices in air conditioner outdoor units, this paper proposed and developed a novel pump-free roll bond aluminum flat-plate loop heat pipe and radiator.Thermal simulation and experimental investigations were carried out on a cabinet air conditioner with rated cooling capacity of 7 600 W, thereby effectively resolving the high-temperature heat dissipation issue of inverter power devices under air-forced cooling conditions.The prototype air conditioner achieved 100% of its rated refrigerating capacity when the ambient temperature of the outdoor unit reached 53 ℃, and was capable of continuous operation even at an outdoor ambient temperature of 62 ℃. This performance enabled the air conditioner to adapt well to the extreme high-temperature weather in summer.

Key words: roll bond, loop heat pipe, heat dissipation, inverter air conditioner, high-temperature cooling
