To provide a new method of manufacturing a multi-plate type housingless oil cooler (a heat exchanger) 10, in which two kinds of heat exchange chambers 14, 15 are alternately formed between a plurality of metal plates.
In a preliminary forming step (A), after the plurality of metal plates 11 to 13 are overlapped, the adjacent metal plates are joined to each other by a plurality of joining parts S1 - S4 including the peripheral part S1 to form a preliminary formed body 10A. In swelling deformation steps B, C, after the preliminary formed body 10A is disposed between a lower mold 31 and an upper mold 32, liquid pressure is supplied from first outlet and inlet 19, 20, thereby swelling and deforming the preliminary formed body to form a first heat exchange chamber 14, and liquid pressure is supplied from second inlet and outlet 21, 22, thereby swelling and deforming the preliminary formed body to form a second heat exchange chamber 15.
