  • Patent number: 9964317
    Abstract: A portable DC air-conditioner has a cooler circulation system inside a housing, including a DC compressor, a condenser, an expansion valve and an evaporator. The evaporator is disposed inside an air duct which has an end thereof connected to a fan and another end thereof forming a discharging exit. The condenser is arranged below the evaporator and the air duct has a guiding tube at the bottom thereof so that the water drops made by the evaporator would be guided to flow into the condenser. A distributing portion is disposed on the housing, including a base connected to the discharging exit and at least one hollow frame having a circular slit on the inner edge for cooled air to be discharged. The evaporator in the air duct would produce cooled air and transport the cooled air to the discharging exit to flow out from the circular slit, forming a cooler circulation system with small volume and great efficiency.
