DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be explained more clearly and completely below in conjunction with the drawings in the embodiments. Of course, the described embodiments are only a part of the present invention but not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative labor are all within the protection scope of the present invention.

[0029] like Figures 1 to 3As shown, a bypass pipe includes a No. 1 pipe fitting 2 connected end to end to form a No. 1 channel 1, wherein a No. 1 partition component 4 is provided in the No. 1 channel 1, wherein the No. 1 partition component 4 partitions the No. 1 channel 1 into at least two independent flow channels 3, and the No. 1 partition component 4 is spirally distributed along the axial direction of the No. 1 pipe fitting 2, and the No. 1 partition component 4 is fixed to the inner wall of the No. 1 pipe fitting 2 by reducing the diameter and extruding the No. 1 pipe fitting 2, while eliminating the gap between the inner wall of the No. 1 pipe fitting 2 and the No. 1 partition component 4, thereby increasing the heat exchange area and causing the fluid to advance in a spiral shape around the axis to improve the heat exchange efficiency. Eliminating the gap allows the No. 1 partition component 4 to transfer heat to the inner wall of the No. 1 pipe fitting 2 through the contact surface with the No. 1 pipe fitting 2, thereby increasing the heat exchange area; the No. 1 pipe fitting 2 has openings at both ends, and the fluid is connected to the port of the No. 1 pipe fitting 2 through a pipeline to achieve fluid inlet and outlet; as shown Figures 2 to 3 As shown, the cross section of the No. 1 partition component 4 is in the shape of a straight line, a cross, a cross, or the like.

[0030] like Figures 4 to 7 As shown, the bypass heat exchanger includes a No. 2 pipe fitting 6 forming a No. 2 channel 5, the No. 1 pipe fitting 2 is distributed in the No. 2 channel 5, and a No. 2 partition assembly 7 is distributed between the No. 2 pipe fitting 6 and the No. 1 pipe fitting 2. The No. 2 partition assembly 7 is spirally distributed along the axis direction of the No. 2 pipe fitting 6. The No. 2 partition assembly 7 is respectively fitted with the outer wall of the No. 1 pipe fitting 2 and the inner wall of the No. 2 pipe fitting 6 by reducing the diameter of the No. 2 pipe fitting 6, and the gap between the No. 2 partition assembly 7 and the outer wall of the No. 1 pipe fitting 2 and the inner wall of the No. 2 pipe fitting 6 is eliminated. The elimination of the gap allows the No. 2 partition assembly 7 to transfer heat from the outer wall of the No. 1 pipe fitting 2 to the inner wall of the No. 2 pipe fitting 6, thereby increasing the heat exchange area. Increasing the heat exchange area allows the fluid to spirally move around the axis to improve the heat exchange efficiency. Figure 5 As shown, the fluid in the No. 2 pipe fitting 6 enters and exits through the No. 1 external interface 61 and the No. 2 external interface 62, and realizes heat exchange with the fluid in the No. 1 pipe fitting 2. The No. 2 partition component 7 and the No. 1 partition component 4 are both distributed in a spiral shape along the axis, which increases the heat exchange stroke and area, and makes the fluid advance in a spiral shape around the axis, further promoting the heat exchange effect, while increasing the fluid disturbance, forming a vortex to facilitate scale discharge; the No. 2 partition component 7 and the No. 1 partition component 4 cooperate with the No. 2 pipe fitting 6 and the No. 1 pipe fitting 2 by a reducing diameter extrusion method, which is simple and efficient, can effectively fix the No. 2 partition component 7 and the No. 1 partition component 4 without generating a gap, and make the No. 2 pipe fitting 6 and the No. 1 pipe fitting 2 form an independent channel, so that the two fluids advance in a spiral shape around the axis in opposite directions respectively, without generating turbulence and improving the heat exchange efficiency.

[0031] The first and second ends of the area between the outer wall of the first pipe fitting 2 and the inner wall of the second pipe fitting 6 are sealed, and the outer wall of the second pipe fitting 6 is respectively provided with a first external interface 61 and a second external interface 62 for fluid in and out; the area between the outer wall of the first pipe fitting 2 and the inner wall of the second pipe fitting 6 can be sealed by a sealing sheet plus a rubber ring or welding, or by Figure 5 As shown, by extending the length of the second pipe fitting 6 and abutting and welding it with the end of the first pipe fitting 2, the area between the outer wall of the first pipe fitting 2 and the inner wall of the second pipe fitting 6 is sealed at both ends.

[0032] The No. 1 external interface 61 and the No. 2 external interface 62 are distributed near the head and tail ends of the No. 2 pipe fitting 6 .

[0033] The fluid inlet and outlet directions of the No. 1 external interface 61 and the No. 2 external interface 62 are opposite to the fluid inlet and outlet directions of the No. 1 pipe fitting 2, which can further increase the temperature difference between the inlet and outlet of the No. 2 pipe fitting 6 and the No. 1 pipe fitting 2 and improve the heat exchange efficiency.

The No. 1 medium enters and exits from the head and end of the No. 1 pipe fitting 2, and exchanges heat with the No. 1 partition component 4 and the inner wall of the No. 1 pipe fitting 2. At the same time, the No. 1 partition component 4 exchanges heat through the contact surface with the inner wall of the No. 1 pipe fitting 2 to expand the heat exchange area. The No. 2 medium enters and exits the No. 2 pipe fitting 6 through the No. 1 external interface 61 and the No. 2 external interface 62 to exchange heat. The No. 2 partition component 7 absorbs the heat of the No. 1 pipe fitting 2 through the contact surface with the inner wall of the No. 1 pipe fitting 2 and transfers the heat through the contact point between the No. 2 partition component 7 and the inner wall of the No. 2 pipe fitting 6, so that the No. 2 medium not only exchanges heat with the outer wall of the No. 1 pipe fitting 2, but also exchanges heat with the No. 2 partition component 7 and the No. 2 pipe fitting 6, thereby increasing the heat exchange area.

[0035] like Figures 8 to 10As shown, a flow-around heater comprises a heating tube 9 and a No. 3 pipe fitting 10 forming a No. 3 channel 11, wherein the heating tube 9 is distributed in the No. 3 channel 11, and a No. 3 partition assembly 8 is distributed between the heating tube 9 and the No. 3 pipe fitting 10, wherein the No. 3 partition assembly 8 is distributed in a spiral along the axis direction of the No. 3 pipe fitting 10, and the No. 3 partition assembly 8 is respectively fitted with the outer wall of the heating tube 9 and the inner wall of the No. 3 pipe fitting 10 by reducing the diameter of the No. 3 pipe fitting 10, and at the same time, the gap between the No. 3 partition assembly 8 and the outer wall of the heating tube 9 and the inner wall of the No. 3 pipe fitting 10 is eliminated, and the heat of the heating tube 9 can be exchanged with the fluid through the No. 3 partition assembly 8 and the outer wall of the heating tube 9 and the inner wall of the No. 3 pipe fitting 10 at the same time, thereby increasing the heat exchange area and causing the fluid to spirally move around the axis to improve the heat exchange efficiency. The areas enclosed by the inner wall of the No. 3 pipe fitting 10 and the outer wall of the heating tube 9 are sealed at both ends, and water flows in and out of the area between the No. 3 pipe fitting 10 and the heating tube 9 through the No. 3 external interface 101 and the No. 4 external interface 102; the No. 3 partition component 8 transfers the heat of the heating tube 9 to the No. 3 pipe fitting 10 through the contact surface between the No. 3 partition component 8 and the No. 3 pipe fitting 10, thereby increasing the heat exchange area; the heating tube 9 generates heat, and the fluid enters the area between the No. 3 pipe fitting 10 and the heating tube 9 for heat exchange, and at the same time, through the No. 3 partition component 8 and the No. 3 pipe fitting 10, the heat exchange stroke and area are increased, and the fluid is made to move in a spiral shape around the axis, significantly improving the heat exchange efficiency.

[0036] The outer wall of the No. 3 pipe member 10 is provided with a No. 3 external interface 101 and a No. 4 external interface 102 for fluid to enter and exit.
