In order to improve the performance and to reduce the weight of air-conditioner, a new type all aluminum micro-channel heat exchanger is applied for heat pump system. The micro-channel heat exchanger has high performance compared with a conventional fin and tube type heat exchanger due to its characteristic configuration. However, there are some challenges, when the micro-channel heat exchanger is applied for heat pump system. One of the most difficult challenges is to improve the drainage of condensed water when it is used as an evaporator. To solve this problem, a new shape is proposed. In addition, the specifications of the heat exchanger, such as louver configurations and tube arrangement, are optimized for heat pump system. As a result, the micro-channel heat exchanger can reduce the weight about one third and the amount of containing refrigerant about one fourth compared with a conventional fin and tube type heat exchanger.
