PURPOSE: A micro channel heat exchanger is provided to reduce the weight of a heat exchanger by removing metal members having low heat exchanging property. CONSTITUTION: A micro channel heat exchanger comprises metal plates(10) and a porous portion(30). The metal plates are installed to be separated from each other. The porous portion comprises an inner porous portion and a surface porous portion. The inner porous portion improves the heat exchanging performance by preventing axial heat exchange. The surface porous portion is installed for absorbing filler materials produced while blazing attaching. |
