Background The main structure of the heat exchanger is a heat exchange tube and heat exchanger fins, the refrigerant flows in the heat exchange tube, the refrigerant releases or absorbs heat to be transferred to the heat exchanger fins, and the heat exchanger fins are used for increasing the contact area between a heat source and air and strengthening the heat transfer process. In the existing heat exchangers, louver-type heat exchanger fins are often adopted to improve heat exchange effects. According to the disclosed heat exchanger fin and heat exchanger (bulletin number: CN 219141612U), in the above application, through the structure of the shutter blade, the wind resistance coefficient of the shutter blade is obviously reduced, the air resistance is reduced, and meanwhile, the surface area of the shutter blade is increased, so that the total heat exchange surface area is increased, the flow field of the leeward side of the heat exchange tube is improved through the arrangement of the spoiler, the heat exchange of the leeward side of the heat exchange tube is enhanced, and the overall heat exchange capacity of the heat exchanger is improved. However, in the practical use process of the device, the heat dissipation fins are almost identical in appearance, so that the heat dissipation fins at the center of the heat radiator are blocked and blocked, the heat exchange efficiency between the heat dissipation fins and the outside flowing air is limited, the overall heat dissipation efficiency of the heat exchanger is reduced to a certain extent, and in view of the above, the resistance-reducing fin heat exchanger is proposed.
