Heat exchanger with optimized mounting structure and mounting method thereof

The invention discloses a heat exchanger with an optimized mounting structure and a mounting method of the heat exchanger, a fixing rod comprises a basic rod and a plurality of sub fixing rods connected in sequence, the outer diameters of the basic rod and the sub fixing rods are gradually reduced, and a plurality of baffle plates are arranged corresponding to the sub fixing rods on the fixing rod; and the inner diameter of the second fixing hole in each baffle plate is consistent with the outer diameter of the corresponding sub fixing rod. According to the heat exchanger with the optimized mounting structure and the mounting method of the heat exchanger, the characteristic that the outer diameters of the basic rod and the multiple sub fixing rods are gradually reduced is adopted, the baffle plates are arranged corresponding to the sub fixing rods on the fixing rods, and the combination of the three arrangements that the inner diameters of second fixing holes in the baffle plates are consistent with the outer
