[0011] The input tube passes through the outer tube and is connected to the inner tube. The output tube is installed on the outer tube and is connected to the outer tube. The inner tube is provided with a through hole coaxially arranged with the output tube and connected to the outer tube. The diameter of the through hole is consistent with the inner diameter of the outer tube. The inner diameter of the output tube is half the diameter of the through hole.

[0012] A spiral sheet is provided between the outer tube and the inner tube, and the spiral sheet cooperates with the outer tube and the inner tube to form a spiral channel.

DETAILED DESCRIPTION

[0018] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description.

[0019] like Figures 1-6As shown, this embodiment provides a high-efficiency multiple vortex heat exchange device, including a composite pipe 1, a first spiral heat exchange tube group 2, a second spiral heat exchange tube group 3, a third spiral heat exchange tube group 4, a first rotating seat 5 and a second rotating seat 6. The first rotating seat 5 and the second rotating seat 6 are respectively rotatably installed at the two ends of the composite pipe 1, and a main pipe 7 is provided at both ends of the composite pipe 1. The first spiral heat exchange tube group 2, the second spiral heat exchange tube group 3 and the third spiral heat exchange tube group 4 are all installed between the connection of the first rotating seat 5 and the second rotating seat 6, and are all connected to the main pipe 7. The second spiral heat exchange tube group 3 is located in the first spiral heat exchange tube group 2, and the third spiral heat exchange tube group 4 is located in the second spiral heat exchange tube group 3. The composite pipe 1 is respectively installed with an input pipe 8 and an output pipe 9 near the first rotating seat 5 and the second rotating seat 6. The first spiral heat exchange tube group 2, the second spiral heat exchange tube group 3 and the third spiral heat exchange tube group 4 are all provided with a sheet-like pipe 10 connected to the first rotating seat 5, and the pipe mouth of the input pipe 8 is inclined toward the sheet-like pipe 10. Specifically, a sliding groove is provided on the first rotating seat 5 and the second rotating seat 6, and a slide rail is provided on the composite pipe 1 to cooperate with the sliding groove. A sealing ring is installed on one side of the first rotating seat 5 and the second rotating seat 6 located in the composite pipe 1. During heat exchange, the cold fluid enters the composite pipe 1 through the input pipe 8, while the hot fluid passes through the main pipe 7 and passes through the sheet-like pipe 10 and enters the first spiral heat exchange tube group 2, the second spiral heat exchange tube group 3 and the third spiral heat exchange tube group 4, and then exchanges heat with the cold fluid. The sheet-like pipe 10 is pushed by the cold fluid and cooperates with the first rotating seat 5 and the second rotating seat 6 to rotate, so that the first spiral heat exchange tube group 2, the second spiral heat exchange tube group 3 and the third spiral heat exchange tube group 4 rotate and cut the cold fluid, thereby increasing the contact area and improving the heat exchange efficiency. In addition, the first spiral heat exchange tube group 2, the second spiral heat exchange tube group 3 and the third spiral heat exchange tube group 4 are provided to perform multiple heat exchanges simultaneously.

[0020] Furthermore, the first spiral heat exchange tube assembly 2 includes four first spiral tubes 201, which are equidistantly arranged around the central axis of the first rotating base 5. The cross-section of the first spiral tubes 201 is rectangular. The rectangular cross-section of the first spiral tubes 201 can better cut the cold fluid and increase the contact area with the cold fluid.

[0021] Furthermore, the second spiral heat exchange tube assembly 3 includes four second spiral tubes 301, which are equidistantly arranged around the central axis of the first rotating base 5. The cross-section of the second spiral tubes 301 is rectangular. The rectangular cross-section of the second spiral tubes 301 can better cut the cold fluid and increase the contact area with the cold fluid.

[0022] Furthermore, the third spiral heat exchange tube assembly 4 includes four third spiral tubes 401, which are equidistantly arranged around the central axis of the first rotating base 5. The cross-section of the third spiral tubes 401 is rectangular. The rectangular cross-section of the third spiral tubes 401 can better cut the cold fluid and increase the contact area with the cold fluid.

[0023] Furthermore, the composite pipe 1 includes an inner tube 101 and an outer tube 102. The inner tube 101 is placed inside the outer tube 102. The first spiral heat exchange tube group 2, the second spiral heat exchange tube group 3, the third spiral heat exchange tube group 4, the first rotating base 5, and the second rotating base 6 are all placed inside the inner tube 101. The cooperation between the inner tube 101 and the outer tube 102 increases the thermal insulation performance of the inner tube 101.

[0024] Furthermore, the input tube 8 passes through the outer tube 102 and is connected to the inner tube 101. The output tube 9 is mounted on the outer tube 102 and is connected to the outer tube 102. The inner tube 101 is provided with a through hole 103 coaxially arranged with the output tube 9 and connected to the outer tube 102. The diameter of the through hole 103 is consistent with the inner diameter of the outer tube 102, and the inner diameter of the output tube 9 is half the diameter of the through hole 103. Specifically, a spiral blade 104 is provided between the outer tube 102 and the inner tube 101. The spiral blade 104 cooperates with the outer tube 102 and the inner tube 101 to form a spiral channel. The output tube 9 is located at the input end of the spiral channel, and the output end of the spiral channel is located on the symmetrical side of the input tube 8. The inner tube 101 is provided with an input port connected to the output end of the spiral channel. The input port is provided with an inclined tube 105 tilted on the inner tube 101, and the tilt direction of the inclined tube 105 is parallel to the tilt direction of the tube opening of the input tube 8. The cold fluid at the end of the inner tube 101 will have a lower temperature than that at the front end that has contacted the sheet-like conduit 10, and will then be directly refluxed and cannot be fully utilized. The wall of the inner tube 101 will be in contact with the cold fluid and its temperature will drop and become cold, and it will not be fully utilized. Therefore, the cold fluid is input into the inner tube 101 through the input tube 8 and moves along the inner tube 101, thereby flowing into the space between the outer surface and the inner tube 101 through the through hole 103 of the inner tube 101, and part of the cold fluid will enter the output tube 9 for recycling and reuse. And since the inner diameter of the output pipe 9 is half the diameter of the through hole 103, a part of the cold fluid flows along the spiral channel with the inner pipe 101 on the outside, thereby performing heat exchange with the inner pipe 101, exchanging the excess cold from the inner pipe 101, and entering the inner pipe 101 through the inclined pipe 105 at the input port for reuse. The setting of the inclined pipe 105 is that after the cold fluid from the input pipe 8 comes in and pushes the sheet-like conduit 10 to stir, a vortex will be formed and flow along the inclined surface of the inclined pipe 105, preventing it from directly rushing into the inclined pipe 105.
