[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Tube heat exchangers are a basic component in the medical industry, especially in in vitro diagnostic (IVD) equipment. By winding tubes around the heat exchanger and injecting fluid into the tubes, the fluid inside the tubes can be heated or cooled, thereby maintaining certain components at a set constant temperature.

[0004] Currently, in the assembly process of heat exchanger components, the general assembly process involves manually winding the pipes onto the surface of the heat exchanger. Manual winding is inefficient, time-consuming, and labor-intensive. Utility Model Content

[0009] This utility model's pipe heat exchange device incorporates a pipe winding mechanism, which includes a connected guide ring and a pushing ring. The inner circumferential surface of the guide ring has a threaded portion that matches a slot on the heat exchanger. During pipe winding, rotating the guide ring causes the threaded portion to engage with the slot, allowing the guide ring to move relative to the heat exchanger along its length. Simultaneously, the pushing ring easily engages the pipe into the slot, thus winding the pipe along the slot onto the heat exchanger. This saves labor, reduces labor intensity, and improves pipe winding efficiency.

[0038] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0039] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0040] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0041] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0042] Tubing heat exchangers are essential components in the medical industry, especially in in vitro diagnostic (IVD) equipment. The surface of the heat exchanger is designed with a grooved structure, in which tubing can be wound and fluid, such as water or other liquid reagents, can be injected into the tubing. This allows the liquid inside the tubing to be heated or cooled, thereby maintaining certain components at a set constant temperature.

[0043] In related technologies, heat exchangers come in various specifications, resulting in different widths of the grooves on them. When the groove width is designed to be larger than the pipe's outer diameter, manual operation is convenient, and the pipe can be easily inserted into the heat exchanger surface. However, under the pressure of the pipe itself, it is very easy for the pipe to become loosely tangled or spring apart. When the groove width is designed to be smaller than the pipe's outer diameter, the pipe can be wedged into the groove to prevent it from coming apart. However, because the pipe's outer diameter is larger than the groove width, and due to the material of the pipe (hard materials have low elastic deformation), manual force is required to press the pipe into the heat exchanger's groove. This leads to finger pain for workers, difficulty in continuous operation, and high labor intensity. In this case, efficiency is low, and long-term operation can affect the health of the operator's fingers. In addition, during the winding process, there may be multiple pipe intersections, human error, etc., which may bend or deform the pipe to be wound, affecting the heating or cooling effect of the pipe, and even affecting the performance and life of the pipe heat exchange device.

[0044] In view of this, this embodiment provides a pipeline heat exchange device 100, which aims to solve the above-mentioned technical problems by setting a guide ring 21 and a push ring 22, wherein the threaded part 2111 on the guide ring 21 is threadedly engaged with the slot 11. During the movement, the pipeline 6 can be easily inserted into the slot 11 by the push ring 22, saving labor, reducing labor intensity, and improving the efficiency of pipe winding.

[0045] like Figures 1 to 9As shown, according to an embodiment of this utility model, a pipeline heat exchange device 100 is proposed. The pipeline heat exchange device 100 includes a heat exchanger 1 and a pipe winding mechanism 2. The surface of the heat exchanger 1 is provided with a spiral groove 11. The width of the groove 11 is slightly smaller than the outer diameter of the pipe 6, allowing the pipe 6 to be inserted into the groove 11, thus preventing the pipe 6 from unraveling and improving the tightness of the pipe winding. The heat exchanger 1 is internally equipped with heat exchange components, such as electric heating wires, resistance wires, or electric heating films, to heat the liquid inside the pipe 6. It can also be equipped with cooling components, such as semiconductor cooling chips, to cool the liquid inside the pipe 6. The pipe winding mechanism 2 is used to wind the pipe 6 around the heat exchanger 1. The pipe winding mechanism 2 includes a guide ring 21 and a push ring 22. The inner circumferential surface of the guide ring 21 is provided with a threaded part 2111. The threaded part 2111 has the same pitch lead as the slot 11. The threaded part 2111 is threadedly connected to part of the slot 11. When the pipe is wound, the guide ring 21 can move up and down along the length direction of the heat exchanger 1 on the outer surface of the heat exchanger 1. The push ring 22 is connected to the guide ring 21 and is sleeved on the outer circumference of the heat exchanger 1. The inner diameter of the push ring 22 is smaller than the inner diameter of the guide ring 21. When the guide ring 21 moves along the heat exchanger 1, the push ring 22 presses the pipe 6 into the slot 11 so that the pipe 6 is locked in the slot 11, thus completing the pipe winding work.

[0046] The pipe heat exchange device 100 of this utility model is provided with a pipe winding mechanism 2, which includes a guide ring 21 and a pusher ring 22 connected together. The inner circumferential surface of the guide ring 21 is provided with a threaded part 2111 that is adapted to the slot 11 on the heat exchanger 1. When winding the pipe, the guide ring 21 is rotated, and the threaded part 2111 on the guide ring 21 is threadedly engaged with the slot 11, so that the guide ring 21 can move relative to the heat exchanger 1 along the length direction of the heat exchanger 1. At the same time, the pipe 6 can be easily inserted into the slot 11 by the pusher ring 22, thereby winding the pipe 6 along the slot 11 onto the heat exchanger 1. It is not necessary to manually press the pipe 6 into the slot 11, saving labor, reducing labor intensity, and improving the efficiency of pipe winding.

[0047] In some embodiments of this utility model, the guide ring 21 includes two semicircular rings, which are connected to form a circular structure. At least one semicircular ring has a threaded portion 2111 on its inner circumferential wall. Specifically, the guide ring 21 includes a first semicircular ring 211 and a second semicircular ring 212. The cross-section of the first semicircular ring 211 and the second semicircular ring 212 is semicircular. The aforementioned cross-section is a plane perpendicular to the axis of the guide ring 21. The first semicircular ring 211 and the second semicircular ring 212 are arranged in a mirror symmetrical manner, forming a ring structure that surrounds the outer surface of the heat exchanger 1. The first semicircular ring 211 and the second semicircular ring 212 can be made of metal, such as stainless steel or aluminum alloy, or plastic, such as POM (polyformaldehyde) or nylon. The diameter of the ring can be changed according to the diameter of different heat exchangers 1 to achieve adaptation. A threaded portion 2111 can be provided on the inner peripheral wall of the first semicircular ring 211, or on the inner peripheral wall of the second semicircular ring 212, or both the first and second semicircular rings 211 and 212 can have threaded portions 2111. It is understood that the threaded portions 2111 on the first and second semicircular rings 211 are connected and have the same pitch lead as the slot 11. All of these methods can achieve the movement of the guide ring 21 relative to the heat exchanger 1 along its length direction through the threaded engagement of the threaded portion 2111 with the slot 11. In this embodiment, the threaded portion 2111 is provided on the inner peripheral wall of the first semicircular ring 211.

[0048] In some embodiments of this utility model, a first connecting component is provided between two semicircular rings. The first connecting component includes a first connecting member 31. One of the two semicircular rings is provided with a first connecting portion 33, and the other is provided with a first mating portion 34. The first connecting member 31 passes through the first connecting portion 33 and the first mating portion 34 to connect the two semicircular rings. Specifically, the first connecting portion 33 includes a first shaft hole provided at one end of the first semicircular ring 211, and the first mating portion 34 includes a second shaft hole provided at one end of the second semicircular ring 212 near the first semicircular ring 211. The first shaft hole and the second shaft hole are adapted to each other. The first connecting member 31 includes a first connecting pin, which passes through the first shaft hole and the second shaft hole, thereby connecting the first semicircular ring 211 and the second semicircular ring 212.

[0049] In some embodiments of this utility model, the first connecting assembly further includes a limiting member 32. One end of the first connecting member 31 is provided with a limiting groove 311. The limiting member 32 is connected to the first connecting member 31 through the limiting groove 311. The limiting member 32 is used to restrict the first connecting member 31 from disengaging from the first connecting portion 33 and the first mating portion 34. Specifically, the limiting member 32 includes a retaining spring 321. The first connecting pin includes a head and a rod portion. A limiting groove 311 is provided at the end of the rod portion away from the head. The limiting groove 311 is adapted to the retaining spring 321 so that the retaining spring 321 is engaged in the limiting groove 311. When assembling the guide ring 21, align the first shaft hole with the second shaft hole, and use the rod of the first connecting pin to pass through the first shaft hole and the second shaft hole, with the head abutting against the guide ring 21 to fix the first connecting pin in the first shaft hole and the second shaft hole. Finally, install the snap ring 321 into the limiting groove 311 to limit the first connecting pin and prevent it from coming out of the first shaft hole and the second shaft hole, thereby improving stability and reliability.

[0050] In some embodiments of this utility model, a second connecting member 41 is provided between two semicircular rings. One of the two semicircular rings is provided with a second connecting portion 42, and the other is provided with a second mating portion 43. The second connecting member 41 passes through the second connecting portion 42 and the second mating portion 43 to connect the two semicircular rings. Specifically, the end of the first semicircular ring 211 away from the first shaft hole is provided with a third shaft hole, and the end of the second semicircular ring 212 away from the second shaft hole is provided with a fourth shaft hole. The third shaft hole and the fourth shaft hole are adapted to each other. The second connecting member 41 includes a second connecting pin, which passes through the third shaft hole and the fourth shaft hole, thereby connecting the first semicircular ring 211 and the second semicircular ring 212.

[0051] It is understandable that a connecting shaft can also be provided at one end of the first semicircular ring 211 and the second semicircular ring 212, so that the first semicircular ring 211 and the second semicircular ring 212 are connected as an integral part through the connecting shaft, and the first semicircular ring 211 and the second semicircular ring 212 can open and close around the connecting shaft. At the same time, a connecting pin is provided at the end of the first semicircular ring 211 and the second semicircular ring 212 away from the connecting shaft, so as to fix the first semicircular ring 211 and the second semicircular ring 212 into a ring structure.

[0052] In some embodiments of this utility model, the propulsion ring 22 includes a ring body 221 in the shape of a ring. The ring body 221 has a first opening 222 and a second opening 223. The second opening 223 is spaced apart from the first opening 222 along the circumference of the ring body 221. The pipe 6 passes through the first opening 222 and the second opening 223 and connects to the propulsion ring 22. Specifically, the gap between the inner diameter of the propulsion ring 22 and the outer diameter of the heat exchanger 1 is precisely controlled between 0.2mm and 0.4mm. For example, the gap between the inner diameter of the propulsion ring 22 and the outer diameter of the heat exchanger 1 can be 0.2mm, 0.3mm, 0.4mm, etc. In this embodiment, 0.3mm is preferred. By setting the above gap value, the inner circumferential wall of the propulsion ring 22 can cooperate with the outer circumferential wall of the heat exchanger 1 during pipe winding, so that the propulsion ring 22 squeezes the pipe 6 into the slot 11, ensuring the uniformity and precision of pipe winding. The ring 221 has a first opening 222 and a second opening 223, which facilitates the sequential passing of the pipe 6 through the first opening 222 and the second opening 223, so that the pipe 6 can be inserted into the push ring 22 for winding. Since the groove 11 on the surface of the heat exchanger 1 in this embodiment does not extend to both ends of the heat exchanger 1, the first opening 222 extends along the axial direction of the ring 221 to both ends of the ring 221, and the second opening 223 extends along the axial direction of the ring 221 to one end of the ring 221. When the pipe 6 is wound to the end of the groove 11, it is convenient for the pipe 6 to be taken out from the push ring 22.

[0053] It is understandable that if the groove 11 on the surface of the heat exchanger 1 extends to both ends of the heat exchanger 1, then two openings that do not extend to both ends of the ring 221 can be opened on the side wall of the ring 221. In this case, it will not affect the removal of the pipe 6 from the push ring 22.

[0054] In some embodiments of this utility model, an assembly structure is provided between the guide ring 21 and the propulsion ring 22. The assembly structure includes a first assembly part 51 and a second assembly part 52. The first assembly part 51 is disposed on one of the guide ring 21 and the propulsion ring 22, and the second assembly part 52 is disposed on the other of the guide ring 21 and the propulsion ring 22. The first assembly part 51 and the second assembly part 52 are detachably connected. Specifically, the first assembly part 51 includes an assembly groove 511, which is disposed at the lower end of the guide ring 21 and extends along the inner circumferential surface of the guide ring 21. The second assembly part 52 includes an assembly boss 521 adapted to the assembly groove 511, which is disposed at the upper end of the propulsion ring 22 and extends along the outer circumferential surface of the propulsion ring 22. When assembling the guide ring 21 and the propulsion ring 22, first insert the first connecting pin into the first shaft hole and the second shaft hole, assemble the first semi-circular ring 211 and the second semi-circular ring 212, and surround them on the outer circumference of the heat exchanger 1. Then, align the mounting boss 521 on the propulsion ring 22 with the mounting groove 511 on the guide ring 21, and use the mounting boss 521 and the mounting groove 511 to engage so that the propulsion ring 22 is assembled to the bottom of the guide ring 21. Finally, tighten the first semi-circular ring 211 and the second semi-circular ring 212, and insert the second connecting pin into the third shaft hole and the fourth shaft hole to complete the assembly of the guide ring 21 and the propulsion ring 22.

[0055] In some embodiments of this utility model, a limiting boss 213 is provided on the guide ring 21. The limiting boss 213 is located at the end where the guide ring 21 connects to the propulsion ring 22 and protrudes from the inner wall of the guide ring 21. The limiting boss 213 is used to abut against the propulsion ring 22 to restrict the circumferential movement of the propulsion ring 22. When winding the tube, the guide ring 21 needs to be rotated so that the guide ring 21 rotates along the slot 11, thereby driving the propulsion ring 22 to rotate with the guide ring 21. By providing the limiting boss 213, the propulsion ring 22 can always rotate in the same direction when it rotates, without causing relative rotation between the propulsion ring 22 and the guide ring 21, thus ensuring the stability and reliability of the tube winding mechanism 2 and further improving the tube winding efficiency.

[0056] It is understandable that the propulsion ring 22 can also be integrated with the first semi-circular ring 211 as an integral structural component, that is, the propulsion ring 22 and the first semi-circular ring 211 can be integrally processed or welded to form an integral structure. Alternatively, the propulsion ring 22 can also be integrated with the second semi-circular ring 212 as an integral structural component, that is, the propulsion ring 22 and the second semi-circular ring 212 can be integrally processed or welded to form an integral structure.

[0057] In this embodiment, the pipeline heat exchange device 100 further includes a temperature sensor and a controller. The temperature sensor detects the temperature of the heat exchanger 1. The signal input terminal of the controller is electrically connected to the signal output terminal of the temperature sensor. The signal output terminal of the controller is electrically connected to the signal input terminal of the heating element or the cooling element. The temperature sensor detects the temperature of the heat exchanger 1 and transmits the detection signal to the controller. The controller controls the start and stop of the heating element or the cooling element according to the detection signal, thereby controlling the temperature of the heat exchanger 1 and keeping the heat exchanger 1 in a set constant temperature state, thereby keeping the temperature of the liquid in the pipeline 6 constant, so as to play a constant temperature protection role for certain components with specific requirements.

[0058] To further understand the pipeline heat exchange device 100 of this application, the working process of the pipeline heat exchange device 100 of this application will be described below with reference to the accompanying drawings.

[0059] First, confirm the reserved length and winding direction of the pipe 6 to be wound. Then, connect the first semi-circular ring 211 and the second semi-circular ring 212 using the first connecting pin, and use the retaining ring 321 to limit and fix the first connecting pin. Please refer to [link to relevant documentation]. Figure 1 The tube winding assembly is placed at the bottom of the heat exchanger 1 as the starting position. When the tube winding mechanism 2 is used, the first semicircular ring 211 and the second semicircular ring 212 are in an open state. The push ring 22 is fitted onto the outer periphery of the heat exchanger 1. The pipe 6 passes through the first opening 222 and the second opening 223 in sequence, and the push ring 22 passes out from the second opening 223. Then, the first semicircular ring 211 and the second semicircular ring 212 are surrounded around the outer periphery of the heat exchanger 1. The threaded part 2111 on the first semicircular ring 211 is aligned with the slot 11. The push ring 22 is then assembled into the mounting slot 511 on the guide ring 21 through the mounting boss 521. Finally, the first semicircular ring 211 and the second semicircular ring 212 are closed, and the guide ring 21 and the push ring 22 are tightened and fixed by the second connecting pin, thus completing the assembly of the tube winding mechanism 2. During the tube winding process, the rotating guide ring 21 engages with the slot 11 via the threaded portion 2111, causing the guide ring 21 to rise along the surface of the heat exchanger 1. Simultaneously, the push ring 22 rotates and rises, pressing the pipe 6 into the slot 11, thus completing the tube winding operation. When the tube winding mechanism 2 reaches the end of the slot 11 at the upper end of the heat exchanger 1, please refer to... Figure 2 At this point, first remove the second connecting pin to open the first semicircular ring 211 and the second semicircular ring 212, then remove the guide ring 21 and the propulsion ring 22 to complete the tube winding work.
