Description of the invention (2) less than the depth of the heat transfer blade 1 0 1 W :, and it is effective to make the sheet pitch P f 2 smaller than the sheet pitch P f 1. Once the depth W becomes smaller, the area of a heat transfer blade will also become smaller, the blade efficiency will increase and the performance will increase. On the one hand, once The smaller the sheet pitch P f, the smaller the representative size of the airflow, and the general heat transfer performance on the air side will be improved. Therefore, the heat transfer surface on the same air side 侧, that is, the same aluminum sheet uses a small depth and the sheet pitch P f is small. The performance of the heat exchanger is poor. Conversely, as long as the heat exchanger has the same performance, the depth W is small and the sheet pitch P f is low. In this way, the segment Pd is limited and the sheet pitch Pf is limited. The heat exchanger with a small depth W is the least expensive. Even, a heat exchanger with a small depth W, It helps to reduce the size of the refrigerating and air-conditioning unit that houses the heat exchanger, and also helps to reduce the cost of the product. It can even increase the distance between the fan and the blower. For low noise.-Once this low-cost heat exchanger is realized, the heat transfer blades 10 1 are elongated shapes extending in the Z direction (long side). This heat transfer blade 1 0 1 becomes less rigid and the heat exchanger The deterioration of the operation during manufacturing and the refrigeration and air-conditioning units using heat exchangers as strength members, in addition to the reduction in the rigidity of the unit itself, will cause strength problems. Because the segment pitch P d is large, blade efficiency is generated, that is, Performance issues such as performance degradation, etc. Figure 20 shows the heat transfer blades of the cross-blade tube heat exchanger related to the conventional technology, (A) is a front view, and (B) is (A) XX — XX Line cross section, (C) is (A) XXI-XXI line cross section.

Description of the invention (12) Use only 2 cut slits for each phase, and count the heat transfer blades in a mesh configuration to actually increase the heat transfer area. At the same time, high heat transfer performance is obtained. Furthermore, by providing a concave-convex strip portion on at least one end of the heat transfer blade, higher rigidity and heat transfer performance can be obtained.
