In air conditioning equipment, a heat exchanger is used as an important component of an air conditioning function, and the heat exchange efficiency of the heat exchanger is directly related to the refrigeration capacity and the energy efficiency of an air conditioner. Besides being influenced by the heat dissipation area of the fins, the heat exchange capacity of the heat exchanger plays a key role in the structure. For example, the heat exchanger of the split on-hook air conditioner is designed into a three-section type appearance in order to better exert the function of the cross-flow fan. In window air conditioners and partial cabinet air conditioners, centrifugal fans are mostly adopted for air supply of indoor air conditioners, the centrifugal fans enable the centers of impellers to generate vacuum degrees through centrifugal action to suck air, and then the air is thrown out through a volute air duct, so that in the common technology, the centrifugal fans and the heat exchangers are generally close to each other in design distance, only an area, slightly larger than the diameter of the fan, in the middle of the heat exchanger can receive the air suction action of the centrifugal fans, and the edge area of the currently and generally adopted rectangular heat exchanger cannot receive the West wind action of the centrifugal fans, so that the heat exchange action of the heat exchanger is greatly reduced.
