the tube side is equipped with main heat exchange tube 11 and assists heat exchange tube 12, be connected with a plurality of vortex pipes 13 along the axial between main heat exchange tube 11 and the assistance heat exchange tube 12, the both ends of vortex pipe 13 respectively with main heat exchange tube 11 and assistance heat exchange tube 12 intercommunication, main heat exchange tube 11 has blind end and open end, the blind end of main heat exchange tube 11 is connected with driving piece 14, driving piece 14 can drive main heat exchange tube 11 and assist heat exchange tube 12 relatively rotatory for vortex pipe 13 rolling or relaxing. Preferably, the driving member 14 is a motor. The main heat exchange tube 11 is made of stainless steel.
Specifically, in the energy-saving stainless steel heat exchanger of the embodiment, hot fluid is introduced through a tube side, cold fluid is introduced through a shell side, the hot fluid and the cold fluid exchange heat in the circulation process, according to actual use conditions, the temperature of the hot fluid introduced into the tube side is changed, the temperature of the cold fluid introduced into the shell side is constant, the temperature difference (delta T) of the fluid between the tube side and the shell side is changed along with the temperature change, when the temperature difference (delta T) is large, the driving piece 14 drives the main heat exchange tube 11 to rotate, the main heat exchange tube 11 synchronously drives each vortex tube 13 to be loosened, and the gap between adjacent tube walls is increased, so that the effective heat exchange area is increased, and the heat exchange of the heat fluid with high temperature can be fully performed;
when the temperature difference (Δt) is small, the driving member 14 drives the main heat exchange tube 11 to reversely rotate, so that each of the scroll tubes 13 is wound, and at this time, the effective heat exchange area is reduced due to the mutual abutting portions between the tube walls of the scroll tubes 13, so as to accommodate heat exchange when the temperature of the hot fluid is relatively low.
According to the embodiment, the main heat exchange tube 11 and the auxiliary heat exchange tube 12 are arranged on the tube side, the plurality of vortex tubes 13 are arranged between the main heat exchange tube 11 and the auxiliary heat exchange tube 12, and the driving piece 14 is arranged to drive the main heat exchange tube 11 to rotate, so that the driving piece 14 drives the main heat exchange tube 11 to rotate, and the vortex tubes 13 are wound or relaxed, so that the effective heat exchange area is changed, the temperature change of hot fluid is suitable, the heat exchange efficiency is improved, the heat loss is reduced, and the energy is saved.
Meanwhile, in the embodiment, the main heat exchange tube 11, the auxiliary heat exchange tube 12 and the vortex-shaped tube 13 are arranged, so that the circulation path of the hot fluid is prolonged, and the heat exchange efficiency is further improved.

Specifically, the elastic tube 131 is made of stainless steel material, so that the elastic tube 131 can drive the flexible tube 132 to deform and recover the deformation when the main heat exchange tube 11 rotates, so as to change the effective heat exchange area. When the temperature difference (delta T) is large, the elastic tube 131 drives the flexible tube 132 to relax, and at the moment, the outer walls of the elastic tube 131 and the flexible tube 132 can be contacted with cold fluid, so that the effect of increasing the effective heat exchange area is achieved, and the heat exchange effect is improved; when the temperature difference (Δt) is small, the elastic tube 131 drives the flexible tube 132 to roll up, so that the outer wall of the flexible tube 132 is pressed against the outer wall of the elastic tube 131, and at this time, the outer wall portions of the elastic tube 131 and the flexible tube 132 are shielded from directly contacting with the cold fluid, thereby achieving the effect of reducing the effective heat exchange area. This embodiment is through setting up flexible pipe 132 to when the rolling, elastic pipe 131 produces the extrusion to flexible pipe 132, makes the deformation volume increase of flexible pipe 132, thereby can cover the area of more elastic pipe 131 outer walls, thereby makes effective heat transfer area's adjustment scope bigger, and the adjustment effect is more obvious.
