Description

Technical Field

[0001] This utility model relates to the field of heat exchange coil technology. More specifically, this utility model relates to a spiral coil with turbulence. Background Technology

[0002] Within a limited space, spiral coils can expand the heat transfer area by increasing the pipe length. Compared with straight tube heat exchangers, they can achieve higher heat exchange in a smaller volume. However, existing spiral coils lack internal turbulence devices, making them prone to scale buildup and noise during use. Scale buildup on the pipe walls reduces heat exchange efficiency, hindering efforts to improve heat exchange efficiency and reduce energy consumption.

[0003] Chinese patent application CN1151016A discloses a baffle plate for enhancing heat exchange in a heat exchange tube. This baffle plate, with an arbitrary curved cross-section, is inserted into the heat exchange tube to enhance heat exchange. It allows the fluid to fully contact the tube wall, thus enhancing heat exchange. It is simple to manufacture and easy to install. However, due to the curved cross-section, the baffle plate's position inside the tube is unstable, easily causing violent shaking when fluid is introduced, resulting in slapping and friction against the inner wall of the tube, affecting the lifespan of the heat exchange tube. Furthermore, this baffle plate is not suitable for flat tubes, as its overall curved structure can easily cause poor fluid flow and even pipe blockage. Utility Model Content

[0004] One object of this invention is to solve the above-mentioned problems and / or defects, and to provide the advantages that will be described later.

[0005] To achieve these objectives and other advantages of this utility model, a spiral coil with turbulence is provided, comprising: a coil body, and turbulence-inducing plates disposed within the coil body, wherein the turbulence-inducing plates are provided with a plurality of recesses and protrusions alternating with each other.

[0006] The width of the recessed portion and the protruding portion is smaller than the width of the spoiler;

[0007] The coil body is configured as a flat tube;

[0008] The recessed portion and the protruding portion abut against the lower end and upper end of the inner wall of the coil body, respectively.

[0009] Preferably, both the recessed portion and the protrusion are configured as spherical.

[0010] Preferably, the turbulence deflector has a strip-shaped opening on the outer side of the spiral that facilitates bending.

[0011] Preferably, the bottom end of the strip-shaped opening is provided with a tear-preventing part;

[0012] The crack-stopping part is configured in an arc shape.

[0013] This utility model has at least the following beneficial effects: by setting baffles inside the coil body, the laminar flow state inside the tube is broken, the degree of fluid turbulence is increased, and more fluid is allowed to contact the tube wall; the service life of the equipment is extended, the fouling on the tube wall is reduced, and the heat exchange efficiency is reduced due to scaling; the baffles are provided with a width smaller than the recessed and raised parts of the baffles, which improves the stability of the baffles while achieving the baffle effect, and prevents them from shaking inside the tube, rubbing against the tube wall, and affecting their service life; at the same time, by setting the recessed and raised parts, the inner wall of the coil body can be prevented from deforming, and sufficient space is reserved for the flow of fluid inside the tube, which can prevent the fluid inside the tube from being blocked and the flow obstructed.

[0014] Other advantages, objectives and features of this invention will be apparent in part from the following description, and in part from the understanding of those skilled in the art through study and practice of this invention. Attached Figure Description

[0026] Example 1

[0027] A spiral coil with turbulence, its structure is as follows: Figure 1-4 As shown, it includes: a coil body 1, a baffle 2 disposed inside the coil body 1, wherein the baffle 2 is provided with a plurality of recesses 21 and protrusions 22 alternately arranged on each other;

[0028] The width of the recessed portion 21 and the protruding portion 22 is smaller than the width of the spoiler 2;

[0029] The coil body 1 is configured as a flat tube;

[0030] The recessed portion 21 and the protruding portion 22 abut against the lower end and the upper end of the inner wall of the coil body 1, respectively.

[0031] In practical applications, the recessed portion 21 and the protruding portion 22 are placed on the center line of the baffle 2 and are evenly distributed along the baffle 2.

[0032] Working principle: The surface of the baffle plate 2 is pressed and stretched out by the mold, and the concave parts 21 and convex parts 22 are evenly arranged in a cross shape. The baffle plate 2 is then inserted into the straight coil body 1 and spirally coiled together by the coiling device. After reserving the length of the inlet and outlet, the coil is cut. The coil after cutting is made by the flaring and flanging forming machine to make the inlet and outlet connection dimensions, thus completing the manufacturing of the spiral coil.

[0033] By setting baffles 2 inside the coil body 1, the laminar flow state inside the tube is broken, the fluid turbulence is increased, and more fluid is allowed to contact the tube wall; this extends the equipment life, reduces the accumulation of fouling on the tube wall, and reduces the decrease in heat exchange efficiency caused by scaling. The baffles 2 have a width smaller than the recessed portion 21 and the protrusion 22, which improves the stability of the baffles 2 while achieving the turbulence effect, preventing them from shaking inside the tube and rubbing against the tube wall, thus affecting their service life. At the same time, the recessed portion 21 and the protrusion 22 can prevent the inner wall of the coil body 1 from deforming, and they reserve enough space for the flow of fluid inside the tube, which can prevent the fluid inside the tube from being blocked and causing poor flow.

[0034] Example 2

[0035] This second embodiment is a preferred embodiment of the present invention, and its specific structure is as follows: Figure 3 As shown, based on embodiment 1, the following improvement is disclosed: both the recessed portion 21 and the protruding portion 22 are configured as spherical.

[0036] Working principle: The spherical shape creates a smoother transition while achieving turbulence, which can prevent deformation of the turbulence plate 2, improve the strength of the turbulence plate 2, and at the same time reserve enough space for the fluid in the coil body 1.

[0037] Example 3

[0038] This third embodiment is a preferred embodiment of the present invention, and its specific structure is as follows: Figure 5 As shown, based on embodiment 1, the following improvement is disclosed: the turbulence plate 2 is provided with a strip-shaped opening 23 on the outer side of the spiral for easy bending.

[0039] The bottom end of the strip-shaped opening 23 is provided with a tear-stopping part 24 to prevent tearing;

[0040] The crack-stopping part 24 is configured in an arc shape.

[0041] Working principle: The surface of the baffle plate 2 is pressed with a mold to form a recessed part 21 and a raised part 22. Then, a strip-shaped opening 23 is processed on one side of the baffle plate 2, and a crack-stopping part 24 is set at the bottom of each strip-shaped opening 23. Then, the baffle plate 2 is inserted into the straight coil body 1, and together they are spirally coiled away from the strip-shaped opening 23 through the coiling device.

[0042] The strip-shaped opening 23 can prevent tearing due to stress concentration at one point caused by bending, which would affect stability. At the same time, the anti-crack part 24 at the bottom of the strip-shaped opening 23 can prevent the bottom of the strip-shaped opening 23 from tearing and breaking.

[0043] The above solutions are merely illustrative examples of preferred embodiments, but are not limited thereto. When implementing this invention, appropriate substitutions and / or modifications can be made according to the user's needs.

[0044] The number of devices and processing scale described herein are for the purpose of simplifying the description of this utility model. Applications, modifications, and variations of this utility model will be readily apparent to those skilled in the art.

[0045] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art.
