◆ 采用昆拓独创的流星结构，机体内冷气流由下而上，先将管路电器元件、压缩机等冷却再流经顶部的冷凝器，最后由风扇排出。Use unique star structure, bottom-top air flow can cool the electrical components, compressor and the condenser from inside.
◆ 根据不同元件对温度的不同要求，冷气流由低到高实现了阶梯状的冷却过程，提高了电器元件、压缩机的稳定性，同时强化了冷凝器的换热能力。According different requirement of different components, cool air circle flows from bottom to top, achieve phase by phase cool process, enhance the stability of electrical components and compressor, and also the heat exchange ability of condenser
◆ 通道内气流始终沿垂直方向流动，避免了同类产品气流需90转向排出的缺陷，使风机效率得以提高。停机状态下热气流垂直上升，有利于机体内部散热。Air flows in the vertical direction will avoid 90 degree air flow defect, increase efficiency of fan, and be better for heat discharge inside the air conditioner when it is down.
◆ 基于昆拓的专利结构,U系列机柜空调器的体积仅为同类产品的1/2左右。精巧的专利快装固定结构，使得安装过程更加简便快捷。Patent structure makes the size of U series is 1/2 as other air conditioner, delicate fast installation device make installation much easier.
