Abstract
In a method for manufacturing a stacking-type, multi-flow, heat exchanger, heat transfer tubes and outer fins are stacked alternately, each heat transfer tube being formed by connecting a pair of tube plates and including an inner fin therebetween. The manufacturing method includes the steps of disposing the tube plates so as to oppose each other, inserting an inner-fin forming material between the tube plates, stacking the tube plates with respect to each other so as to nip or seize the inner-fin forming material between the tube plates, and cutting the inner-fin forming material and end portions of the tube plates simultaneously. By this method, the time for required manufacturing heat transfer tubes may be reduced significantly, and the productivity of the heat exchanger may be increased significantly. The positioning of inner fins may be achieved with a high degree of accuracy. Therefore, a stacking-type, multi-flow, heat exchanger having superior performance qualities and manufactured with a high degree of reliability may be manufactured at a reduced cost.
