<p>PROBLEM TO BE SOLVED: To provide a heat exchanger capable of reducing the number of component elements.SOLUTION: A heat exchanger used as an evaporator including a cold storage function comprises plural flat heat exchanging pipes 12 with their longitudinal direction being directed toward a vertical direction and arranged to be spaced apart to each other under a state in which their width directions being faced toward an aeration direction and fins arranged at aeration clearances formed between the adjoining heat exchanging pipes. The heat exchanging pipes 12 are formed with plural pipe passages 17, 18 where thermal transferring medium flows while being arranged in a width direction. A width of at least one pipe passage 17 of all pipe passages 17, 18 in the heat exchanging pipes is made wider than of the other pipe passage 18. A solid phase sensitive heat storage material 19 made of material having larger thermal capacity per unit volume than that of metal forming the heat exchanging pipes 12 is arranged in a wide width pipe passage 17 of the heat exchanger pipes 12 in such a way that a flowing clearance 20 is formed between it and the inner surface of the pipe passage 17.</p> |
