The finned tube air heat exchanger is widely applied to various industrial projects such as power plants, power, petroleum, chemical engineering, environmental protection, medicine, food, heating/cooling and the like. In the traditional various heat exchangers, because a large number of fins are welded or rolled on the outer surface of the heat exchange tube of the finned tube air heat exchanger, the heat exchange area is effectively enlarged by multiple times, and the finned tube air heat exchanger is applied to various heat exchange occasions. Especially, when gas-liquid heat exchange or gas-steam heat exchange is carried out, because the gas density is low and the fin side is taken, liquid or steam flows in the tube, and the heat exchange area inside and outside the fin tube is effectively and fully utilized.
In the conventional finned tube heat exchanger, the air duct volume is large because the windward area of the air side is large. Therefore, when the gas side pressure is large, the gas side contact surface is wide, the volume is large, and therefore the gas side shell cannot bear higher pressure, and the gas side shell is easily pressed and deformed under the higher pressure condition, even the equipment is damaged, and the heat exchange function is stopped. The pressure bearing of the gas side in the traditional finned tube air heat exchanger is generally not over 100KPa, so the finned tube air heat exchanger is not suitable for being applied to various occasions with high-pressure gas on the air side. Of course, a shell-and-tube heat exchanger can be selected in consideration of the pressure bearing problem, and the shell-and-tube heat exchanger is really resistant to high temperature and high pressure compared with a finned tube air heat exchanger. However, when the shell pass is in a gas working condition, the gas volume is large, the shell-and-tube heat exchange area is small only by heat exchange on two side surfaces of the wall surface of the heat exchange tube, and the cost is multiplied because the heat exchange tube is required to be greatly increased and the shell of the equipment is enlarged.
