[0035] The inlet pipe 21 is on the other side of the bottom end of the tank body. The fluid enters the inside of the heat exchanger tank body 1 through the inlet pipe 21. After heat exchange through the heat exchange inner tube 3, it is discharged through the water outlet pipe 20 located on one side of the top end of the tank body. The fluid flows outside the heat exchange inner tube 3. Since the mounting members 2 provided at both ends of the tank body can rotate, the heat exchange inner tube 3 can rotate inside the tank body. The driving motor 11 drives the mounting member 2 to rotate through the meshing transmission of the driving gear 12 and the driven gear 13. The heat exchange fluid enters the inside of the connecting pipe 4 through the extension pipe 6 on the side of the water outlet pipe 20, then disperses into the inside of the heat exchange inner tube 3, and then is centrally collected at the connecting pipe 4 on the side of the inlet pipe 21 and discharged through the extension pipe 6.
