PROBLEM TO BE SOLVED: To maintain, in a heat exchanger in which plural heat exchange elements have plural flat tubes lined vertically and are arranged in multiple rows via a turn-round header, the efficiency of the heat exchanger by preventing the occurence of liquid stagnation in the turn-round header and letting a gas-liquid two phase refrigerant flow equally into the respective flat tubes of the heat exchanger elements on the downstream side. ! SOLUTION: A heat exchanger comprises: first heat exchange elements 1 having plural flat tubes 1A lined vertically; second heat exchange elements 2 having plural flat tubes 2A lined vertically; a turn-round header 3 which connects one ends 1Z of the first heat exchange elements 1 with one ends 2Z of the second heat exchange elements 2 to turningly introduce the refrigerant passed through the first heat exchange elements 1 into the second heat exchange elements 2. The turn-round header 3 has plural refrigerant turn-round spaces 3A divided vertically, and one of th |
