Claims (1)

[Scope of utility model registration request] In a heat exchanger in which a plate-shaped porous refrigerant pipe having a plurality of refrigerant passages is meandered and corrugated fins are provided between the meandering porous refrigerant pipes, the refrigerant supply pipe is installed in a refrigerant distribution pipe to be connected to a refrigerant supply pipe. A refrigerant outlet pipe connected to the refrigerant supply pipe itself or to the refrigerant supply pipe has a diameter smaller than that of the refrigerant distribution pipe, and extends to a length that allows a distance of about 5 to 20 rpm between the refrigerant distribution pipe and the terminal end of the refrigerant distribution pipe. A heat exchanger characterized by:
