The six arc-shaped plates 1011 can be adjusted to a suitable angle to form a certain installation taper angle. Then, the sealing cover 1018 is clamped and fixed on the surface of the adjustment groove 1016 for protection. Therefore, when the upper air duct main body 100 of the heat exchanger is installed, it is convenient to adjust the ends of the six arc-shaped plates 1011 to correspond to the surface of the heat exchanger inlet, smoothly and evenly and effectively introduce heat, thereby improving the convenience of taper adjustment and installation when the upper air duct main body 100 of the heat exchanger is installed on the heat exchanger for use;
