[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] This utility model provides a pipeline heat dissipation device, which can solve the technical problem of high energy consumption in traditional refrigeration equipment in related technologies.

[0033] See Figure 1 As shown in the figure, this utility model provides a pipeline heat dissipation device, which includes a cylindrical heat-conducting pipe section 1 and multiple heat sinks 2. The cylindrical heat-conducting pipe section 1 is sleeved around the outer periphery of the pipeline 3 to be cooled, and the multiple heat sinks 2 are evenly and spaced around the cylindrical heat-conducting pipe section 1. In this utility model embodiment, the cylindrical heat-conducting pipe section 1 is sleeved around the outer periphery of the pipeline 3 to be cooled, and multiple heat sinks 2 are spaced apart. The cylindrical heat-conducting pipe section 1 is made of a high thermal conductivity material. Together with the multiple heat sinks 2, it ensures rapid absorption and even dispersion of high-temperature heat on the surface of the pipeline 3 to be cooled, avoiding local heat accumulation. The multiple heat sinks 2 are evenly and spaced around the outer periphery of the cylindrical heat-conducting pipe section 1, which greatly increases the contact area with air, ensures smooth airflow, improves heat dissipation intensity, and eliminates the need to install additional cooling equipment for the pipeline to be cooled, thus saving energy.

[0034] The pipeline heat dissipation device provided in this embodiment includes a cylindrical heat-conducting pipe section and multiple heat sinks. The pipeline heat dissipation device reduces the risk of local heat accumulation. The multiple heat sinks are evenly and spaced on the outer periphery of the cylindrical heat-conducting pipe section, which greatly increases the contact area with air, ensures smooth airflow, and improves heat dissipation intensity. There is no need to install additional cooling equipment for the pipeline to be cooled, thus saving energy.

[0035] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 2As shown, the cylindrical heat-conducting pipe section 1 has two semi-cylindrical shells 11, which are disposed opposite to each other on the outer periphery of the pipe 3 to be cooled, and the two semi-cylindrical shells 11 are detachably connected. In this embodiment of the present invention, the cylindrical heat-conducting pipe section 1 has a split structure, including two semi-cylindrical shells 11, which are disposed opposite to each other on the outer periphery of the pipe 3 to be cooled, and the two semi-cylindrical shells 11 are detachably connected. The cylindrical heat-conducting pipe section has a simple structure, is easy to install and disassemble, and improves the efficiency of installing and disassembling the cylindrical heat-conducting pipe section on the pipe to be cooled.

[0036] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 2 As shown, a connecting portion 4 is also provided. The connecting portion 4 has two protrusions 41 and two grooves 42 corresponding to each of the protrusions 41. The two protrusions 41 are respectively provided on both sides of the mating end face 111 of one of the semi-cylindrical shells 11, and the two grooves 42 are provided on both sides of the mating end face 111 of the other semi-cylindrical shell 11. Each protrusion 41 is used to be embedded in the corresponding groove 42. In this embodiment of the present invention, the two semi-cylindrical shells 11 are detachably connected by the connecting portion 4. The connecting portion 4 includes at least two sets of protrusions 41 and grooves 42. When a pipe cooling device needs to be installed, the two semi-cylindrical shells 11 are pressed so that each protrusion 41 is embedded in the corresponding groove 42, thereby achieving a detachable connection. The connection method is simple and flexible.

[0037] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 and Figure 3 As shown, a clamp 5 is also provided, which is sleeved on the outer periphery of the two semi-cylindrical shells 11. The clamp 5 is used to detach and connect the two semi-cylindrical shells 11. In this embodiment of the utility model, there are two clamps 5, which are spaced apart on the outer periphery of the two semi-cylindrical shells 11. The clamp connection is stable, and the high strength of the clamp can resist loosening caused by long-term vibration or thermal expansion and contraction. At the same time, it is easy to disassemble, which improves the stability and convenience of the heat dissipation device.

[0038] As an optional implementation, in one embodiment of the utility model, the clamp 5 is made of stainless steel. The stainless steel clamp 5 is used to fix the two semi-cylindrical shells 11 in the heat dissipation device. The stable mechanical constraint ensures that the semi-cylindrical shells 11 are in contact with the pipeline 3 to be cooled, thereby improving the heat conduction efficiency. At the same time, the stainless steel material has high temperature resistance and corrosion resistance, adapts to harsh working environments, and is easy to install, taking into account both reliability and maintenance convenience.

[0039] As an optional implementation, in one embodiment of the invention, each heat sink 2 and the cylindrical heat pipe segment 1 are integrally formed by welding or 3D printing. Welding firmly connects the heat sink 2 and the cylindrical heat pipe segment 1, forming a continuous, low-thermal-resistance heat conduction path, improving heat dissipation efficiency and enhancing structural stability. Welding also prevents loosening caused by vibration or thermal cycling, improving long-term reliability. In this embodiment, the heat sink 2 and the cylindrical heat pipe segment 1 can also be integrally formed by 3D printing, resulting in a simple structure and high reliability.

[0040] As an optional implementation, in one embodiment of the utility model, the cylindrical heat-conducting pipe section 1 is made of copper or aluminum. The copper cylindrical heat-conducting pipe section 1 has good thermal conductivity, large heat capacity and is durable, while the aluminum cylindrical heat-conducting pipe section 1 is lightweight and easy to process.

[0041] As an optional implementation, in one embodiment of the invention, the thickness of each heat sink 2 is 0.2-2 mm. Arranging multiple heat sinks 2 at equal intervals and controlling the thickness within the 0.2-2 mm range ensures, firstly, uniform airflow distribution among the heat sinks 2, preventing localized heat accumulation and maximizing the utilization of the heat dissipation surface area. When air flows through the equidistant heat sinks 2, stable laminar or turbulent flow is formed, effectively carrying away heat and improving heat dissipation efficiency. Secondly, the 0.2-2 mm thickness ensures structural strength while avoiding material waste and increased weight. Heat sinks that are too thin may deform due to insufficient strength, while those that are too thick will increase thermal resistance and reduce thermal conductivity. The combination of equidistant arrangement and optimized thickness balances heat dissipation capacity and space occupation, enabling the heat dissipation device to achieve optimal heat dissipation performance.

[0042] As an optional implementation, in one embodiment of the invention, each heat sink 2 is spaced 1-5mm apart. Controlling the spacing between each heat sink 2 within this range ensures that a stable convection channel is formed between each heat sink 2. This avoids both excessively small spacing leading to increased wind resistance and obstructed airflow, and excessively large spacing reducing the effective heat dissipation area. The airflow can fully contact the surface of each heat sink 2, quickly carrying away heat. Simultaneously, this design also maintains structural compactness, maximizing the number of heat sinks within a limited space, thus improving the heat dissipation capacity per unit volume.

[0043] As an optional implementation, in one embodiment of the utility model, the diameter of the cylindrical heat-conducting pipe section 1 is within 5mm larger than the diameter of the pipe to be cooled 3. A gap is reserved between the cylindrical heat-conducting pipe section 1 and the pipe to be cooled 3. Firstly, this gap can effectively compensate for tolerances during manufacturing and assembly, avoiding difficulties in fitting the cylindrical heat-conducting pipe section 1 or deformation due to pipe diameter deviation or installation offset, thus improving the adaptability of the heat dissipation device.
