In many electric heating devices, it is necessary to use a straight finned tube as a core member for heat exchange. The fin straight pipe comprises an internal heating pipe (generally a straight steel pipe) and metal fins wound and fixed on the steel pipe, when the fin straight pipe is used, a heat flow medium passes through the steel pipe, and heat is radiated out through the metal fins to realize heat exchange.
The fin straight tube preparation method generally adopts a single steel tube and a metal belt, and then the metal belt is vertically wound and fixed on the steel tube to prepare the fin. One of the existing fin straight tubes is to prepare a spring-shaped metal band in a superposed ring shape, then penetrate a steel tube into an inner ring of the spring-shaped metal band, stretch and screw the spring-shaped metal band to reduce the inner ring of the spring-shaped metal band and attach the spring-shaped metal band to the steel tube, and the processing method has the defects of poor attachment and easy looseness; the defects of inconvenient processing and poor safety are overcome, and the problem of uneven thread pitch of the fins is easily caused.
In the prior art, a processing mode of winding and welding and fixing by processing equipment is adopted. For example, CN107855647A discloses a laser welding forming process for straight fin tubes, which comprises the following steps: (1) fixing one end of a straight steel pipe in the center of a chuck, and clamping the other end of the straight steel pipe between a pair of pinch rollers; (2) a steel strip coil is arranged above a straight steel pipe between a chuck and a pinch roll, the steel strip coil is driven by a servo motor to release a steel strip downwards, a centering wheel is arranged close to the side of the straight steel pipe, a deep groove is formed in the circumferential direction of the centering wheel, the width of the deep groove is equal to the thickness of the steel strip, one side of the steel strip is embedded into the deep groove, and the other side of the steel strip is in contact with the surface of the straight steel pipe; (3) the steel strip is guided to the straight steel tube at a constant speed under the drive of the servo motor, and when the steel strip is wound on the straight steel tube, the contact part of the steel strip and the straight steel tube is fixed through laser welding. For example, CN1278812C discloses a method for welding heat dissipation fins for a heat exchanger, which is characterized in that an end portion of a stainless steel band is vertically welded on a wall of a steel tube, the steel tube rotates at a constant speed, a tension pre-tightening force is applied to the stainless steel band, the steel band is vertically and spirally wound on the steel tube under the traction of the rotating steel tube, during winding, a tungsten electrode of an argon arc welding gun is aligned to a horizontal tangent point of the stainless steel band and the steel tube, and during welding, current is output to a stable arc, so as to weld the root portion of the heat dissipation fins.
According to the two existing fin straight tube preparation methods, the steel tube is driven to rotate by means of a machine tool, the steel belt is forcibly wrapped on the steel tube in the vertical direction, and then the steel belt is fixed in a welding mode. In the mode, the steel belt is forcibly wound, the stress of equipment is larger, the steel belt is easy to crack, the safety is poorer, meanwhile, the welding cost is higher, gaps are easy to appear on welding seams, and the heat conduction performance of the prepared product is poorer.
