The heat exchange tube 101 realizes heat exchange. Two slots 201 are respectively fitted into the left and right sides of the casing 1. On both sides, the clamping tube 202 can be clamped inside the clamping groove 201. The tube sheet 203 has a number of through holes inside, corresponding to the heat exchange tube 101, which are used to support and fix the heat exchange tube 101 and ensure the stability of the heat exchange tube 101 inside the shell 1. The second mounting plate 204 is installed and connected to the first mounting plate 104 on the outer surface of the shell 1. The fixed cylinder 205 can be connected to the shell 1 through the clamping tube 202. The fluid enters the fixed cylinder 205 on the left side through the second liquid inlet pipe 206 and flows outward through the second liquid outlet pipe 207 on the lower surface of the fixed cylinder 205 on the right side. The discharge plate 208 is vertically connected to the lower left center of the left fixed cylinder 205 on one side, and is used to place the motor 209. The sealing gasket 210 is used to ensure the sealing between the motor 209 and the fixed cylinder 205. The motor 209 drives the spiral blade 212 to run inside the fixed cylinder 205 through the rotating rod 211. After the fluid enters the inside of the left fixed cylinder 205 through the second liquid inlet pipe 206, under the action of centrifugal force, the spiral blade 212 drives the fluid to form a swirling flow and enter the heat exchange tube 101 evenly.

One type of fluid is introduced into the interior of the housing 1 through the first liquid inlet pipe 102, and another type of fluid is introduced into the left fixed cylinder 205 through the second liquid inlet pipe 206. The motor 209 drives the spiral blades 212 to rotate through the rotating rod 211 to generate swirling flow, which sends the fluid into the heat exchange tube 101 for heat exchange. The fluid after heat exchange enters the right fixed cylinder 205 and is discharged through the second liquid outlet pipe 207. The fluid inside the housing 1 is discharged outward through the first liquid outlet pipe 103.
