To provide a heat exchanger using carbon dioxide as refrigerant.
This heat exchanger is characterized by including first and second header pipes having, at least, two or more compartments mutually spaced at prescribed intervals, disposed in parallel to each other, mutually separated by partitions; multiple tubes independently communicating the respective opposite compartments of the first and the second header pipes and, at least, having two or more tube groups having a single refrigerant pass simultaneously passing the refrigerant; a refrigerant inflow pipe formed in the compartment positioned in one side end part of the first header pipe and passing the refrigerant into the first header pipe; multiple return holes formed in the partitions and communicating the both adjoining compartments to each other, and allowing the refrigerant to pass through the tubes in order; and a refrigerant outflow pipe formed in the compartment of the header pipe communicating with the last tube group out of the tube groups according to the flow of the refrigerant out of the first and the second header pipes, and allowing the refrigerant to flow out.
