DETAILED DESCRIPTION
[0028] In order to make the technical personnel in the art better understand the technical scheme of the utility model, the utility model will be described more clearly and more completely below in conjunction with the drawings in the embodiments, of course, the described embodiments are only a part of the utility model but not all, based on the embodiment, the technical personnel in the art obtains other embodiments without paying the creative labor, all are within the protection scope of the utility model.
[0029] AsFigures 1 to 3 As shown, a flow-around tube includes a first pipe fitting 2 connected end-to-end to form a first channel 1. A first partition component 4 is provided within the first channel 1, dividing the first channel 1 into at least two independent flow channels 3. The first partition component 4 is spirally distributed along the axial direction of the first pipe fitting 2. The first partition component 4 is fixed to the inner wall of the first pipe fitting 2 by reducing its diameter and extruding it, simultaneously eliminating the gap between the inner wall of the first pipe fitting 2 and the first partition component 4, increasing the heat exchange area and causing the fluid to flow spirally around the axis to improve heat exchange efficiency. Eliminating the gap allows the first partition component 4 to transfer heat to the inner wall of the first pipe fitting 2 through its contact surface, increasing the heat exchange area. The first pipe fitting 2 is open at both ends, and fluid is connected to the ports of the first pipe fitting 2 via pipes to achieve fluid inflow and outflow. Figures 2 to 3 As shown, the cross-section of the first separator component 4 is in the shape of a straight line, a cross, a star, or similar.
[0030] like Figures 4 to 7 As shown, the flow-around heat exchanger includes a second pipe fitting 6 forming a second channel 5. A first pipe fitting 2 is distributed within the second channel 5. A second partition assembly 7 is distributed between the second pipe fitting 6 and the first pipe fitting 2. The second partition assembly 7 is spirally distributed along the axis of the second pipe fitting 6. By reducing the diameter of the second pipe fitting 6, the second partition assembly 7 is made to fit against the outer wall of the first pipe fitting 2 and the inner wall of the second pipe fitting 6, respectively. This simultaneously eliminates the gaps between the second partition assembly 7 and the outer wall of the first pipe fitting 2 and the inner wall of the second pipe fitting 6. Eliminating these gaps allows the second partition assembly 7 to transfer heat from the outer wall of the first pipe fitting 2 to the inner wall of the second pipe fitting 6, increasing the heat exchange area and causing the fluid to flow spirally around the axis, thereby improving heat exchange efficiency. Figure 5 As shown, the fluid in pipe fitting 6 enters and exits through external ports 61 and 62, and exchanges heat with the fluid in pipe fitting 2. Separating components 7 and 4 are spirally distributed along the axis, increasing the heat exchange stroke and area, and causing the fluid to spiral around the axis, further promoting heat exchange. This also increases fluid turbulence, forming vortices that facilitate scale removal. Separating components 7 and 4 are fitted with pipe fitting 6 and 2 through a diameter reduction and extrusion method. This simple and efficient method effectively fixes separating components 7 and 4 without creating gaps, and allows pipe fitting 6 and 2 to form independent channels, enabling the two fluids to spiral around the axis in opposite directions, preventing turbulence and improving heat exchange efficiency.
[0031] The first and last ends of the area between the outer wall of the first pipe 2 and the inner wall of the second pipe 6 are in a sealed state, and the outer wall of the second pipe 6 is respectively provided with a first external interface 61 and a second external interface 62 for fluid inlet and outlet; the area between the outer wall of the first pipe 2 and the inner wall of the second pipe 6 can be sealed by sealing sheet plus rubber ring or welding, and also by Figure 5 As shown, by extending the length of the second pipe 6 and abutting and welding the end of the first pipe 2, the first and last ends of the area between the outer wall of the first pipe 2 and the inner wall of the second pipe 6 are in a sealed state.
[0032] The first external interface 61 and the second external interface 62 are distributed near the two ends of the second pipe 6.
[0033] The fluid inlet and outlet directions of the first external interface 61 and the second external interface 62 are opposite to the fluid inlet and outlet direction of the first pipe 2, which can further increase the temperature difference of the inlet and outlet of the second pipe 6 and the first pipe 2, and improve the heat exchange efficiency.
[0034] By reducing the diameter of the extrusion, the gap between the first partition assembly 4 and the inner wall of the first pipe 2 is eliminated, and by reducing the diameter of the extrusion, the gap between the second partition assembly 7 and the outer wall of the first pipe 2 and the inner wall of the second pipe 6 is eliminated. The first medium enters and exits from the first and last ends of the first pipe 2, exchanges heat with the first partition assembly 4 and the inner wall of the first pipe 2, and the first partition assembly 4 exchanges heat with the contact surface of the first pipe 2, expanding the heat exchange area. The second medium enters and exits the second pipe 6 through the first external interface 61 and the second external interface 62, and exchanges heat with the second partition assembly 7 and the inner wall of the second pipe 6. The second partition assembly 7 absorbs the heat of the first pipe 2 through the contact surface of the first pipe 2 and transfers the heat through the contact point between the second partition assembly 7 and the inner wall of the second pipe 6, so that the second medium not only exchanges heat with the outer wall of the first pipe 2, but also exchanges heat with the second partition assembly 7 and the second pipe 6, increasing the heat exchange area.
[0035] As shown in Figures 8 to 10As shown, a flow heater includes a heating pipe 9, further includes a third pipe fitting 10 forming a third channel 11, the heating pipe 9 is distributed in the third channel 11, a third separation assembly 8 is distributed between the heating pipe 9 and the third pipe fitting 10, the third separation assembly 8 is helically distributed along the axis direction of the third pipe fitting 10, the third separation assembly 8 is attached to the outer wall of the heating pipe 9 and the inner wall of the third pipe fitting 10 by reducing the diameter of the third pipe fitting 10 to extrude, meanwhile the gap between the third separation assembly 8 and the outer wall of the heating pipe 9 and the inner wall of the third pipe fitting 10 is eliminated, the heat of the heating pipe 9 can be exchanged with the fluid through the third separation assembly 8 and the outer wall of the heating pipe 9 and the inner wall of the third pipe fitting 10 at the same time, the heat exchange area is increased and the fluid advances helically around the axis to improve the heat exchange efficiency.
[0036] The outer wall of the third pipe fitting 10 is respectively provided with a third external interface 101 and a fourth external interface 102 for the fluid to enter and exit.
