Abstract

The invention discloses a heat exchanger and air conditioning equipment. The heat exchanger comprises fins. The fins comprise the front-row fins and the rear-row fins. The front-row fins and the rear-row fins are sequentially distributed in the flowing direction of heat exchange media flowing through the fins, and the wind resistance of the front-row fins is smaller than that of the rear-row fins. In the heat exchanger, due to the fact that the wind resistance of the front-row fins is smaller than that of the rear-row fins, the losses generated when the heat exchange media flow through the front-row fins are reduced, correspondingly, the quantity of the heat exchange media flowing through the rear-row fins is increased, and therefore the heat exchange amount of the rear-row fins and the heat exchange media is increased, and the heat exchange effect of the heat exchanger is improved.
