Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange tubes, in particular to a three-dimensional heat exchange tube. Background Art

[0002] As the core heat exchange element of a heat exchanger, the heat exchange tube has always been a research hotspot in the heat exchange technology field. At present, most of the heat exchange tubes on the market are three-dimensional finned heat exchange tubes. When the existing heat exchange tubes and air-cooling methods are used to cool viscous fluids, the temperature of the viscous fluid can usually only be cooled to about 15°C higher than the ambient temperature. Although various methods are used to change the heat exchange area of the heat exchange tube and eliminate the contact thermal resistance, it can only cool the temperature of the viscous fluid to about 13°C higher than the ambient temperature. An effective method or heat exchange tube has never been found to cool the viscous fluid to the ambient temperature, which is also a major technical problem that has plagued the heat exchange technology field for many years.

[0003] In the prior art, a three-dimensional finned heat exchange tube is mentioned in the patent number (CN201821405737.1), which includes a three-dimensional finned tube with inner fins and outer fins. A throttling part for locally throttling the fluid to be cooled is arranged on the three-dimensional finned tube. The throttling part is arranged inside or outside the three-dimensional finned tube, and a clearance fit of 0-5 mm is formed between the outer wall or inner wall of the throttling part and the fin end of the three-dimensional finned tube. It cleverly uses the throttling principle. During the heat exchange process, all viscous fluids must flow through the gap between the wall of the throttling part and the fin end of the three-dimensional finned tube, so that all viscous fluids can fully adhere to the wall and be heat-exchanged and cooled inside the three-dimensional finned tube, solving the technical problem of poor cooling effect of viscous fluids.

[0004] In the prior art, a throttling part is added, which effectively solves the problem of poor cooling effect of viscous fluids. However, since the whole is still installed relying on an external installation mechanism or a card slot during installation, and there is no installation and sleeving mechanism on its own, the heat exchange tube will deviate from its original position during long-term use, and the ideal heat exchange effect cannot be achieved. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a three-dimensional heat exchange tube, which solves the problem that since the whole is still installed relying on an external installation mechanism or a card slot during installation, and there is no installation and sleeving mechanism on its own, the heat exchange tube will deviate from its original position during long-term use, and the ideal heat exchange effect cannot be achieved.

[0006] To achieve the above object, a three-dimensional heat exchange tube adopted by the present utility model comprises a finned tube, a throttling part and a mounting collar. The mounting collar comprises a ring body, a mounting post, a cavity and a chamfer groove. The throttling part is arranged inside the finned tube. The ring body is detachably connected to the finned tube and is located on the outer surface of the finned tube. The mounting post is fixedly connected to the ring body and is located on the outer surface of the side of the ring body away from the finned tube. The cavity is fixedly connected to the ring body and is located at the center inside the ring body. The chamfer groove is fixedly connected to the ring body and is located at one end of the ring body away from the finned tube.

[0007] Wherein, the finned tube comprises a tube body, inner fins and outer fins. The tube body is arranged on the outer surface of the throttling part and is also arranged inside the ring body. The inner fins are fixedly connected to the tube body and are located on one side inside the tube body, and the inner fins are arranged between the tube body and the throttling part. The outer fins are fixedly connected to the tube body and are located on the outer surface of the tube body, and the outer fins are arranged on one side of the ring body.

[0008] Wherein, the throttling part comprises a first pipe section and a second pipe section. The first pipe section is arranged inside the tube body and is also arranged on the side of the inner fins away from the tube body. The second pipe section is fixedly connected to the first pipe section and is located on one side of the first pipe section, and the second pipe section is arranged inside the tube body and is also arranged on the side of the inner fins away from the tube body.

[0009] Wherein, the throttling part further comprises a spring and a steel ball. The spring is arranged inside the first pipe section. The steel ball is arranged inside the first pipe section and is also arranged on one side of the spring.

[0010] Wherein, the throttling part further comprises a throttling plate. The throttling plate is arranged inside the second pipe section.

[0011] A three-dimensional heat exchange tube of the present utility model comprises a finned tube, a throttling portion and a mounting collar. The mounting collar includes a ring body, a mounting post, a cavity and a chamfer groove. The throttling portion is disposed inside the finned tube. The ring body is detachably connected to the finned tube and located on the outer surface of the finned tube. The mounting post is fixedly connected to the ring body and located on the outer surface of the ring body away from the finned tube. The cavity is fixedly connected to the ring body and located at the center inside the ring body. The chamfer groove is fixedly connected to the ring body and located at one end of the ring body away from the finned tube. Due to the addition of the mounting collar, the problem that the heat exchange tube will be disengaged from its original position during long-term use and cannot achieve the ideal heat exchange effect because the whole is still installed relying on an external installation mechanism or a card slot during installation and there is no mechanism for sleeving installation on its own will be effectively solved.

Therefore, while retaining the original structure and the original beneficial effects, the mounting collar 3 is added, which actively and effectively solves the problem that the heat exchange tube is still installed by relying on an external mounting mechanism or a slot during installation, and there is no mounting mechanism itself, which will cause the heat exchange tube to be separated from the original position during long-term use and fail to achieve the ideal heat exchange effect.

[0021] For this specific embodiment, the intercepting part 2 is arranged inside the finned tube 1. The ring body 301 is detachably connected to the finned tube 1 and is located on the outer surface of the finned tube 1. The mounting post 302 is fixedly connected to the ring body 301 and is located on the outer surface of the ring body 301 on the side away from the finned tube 1.

At the same time, the cavity 303 will be filled with inert gas, thereby maintaining a long service life. At the same time, the chamfered groove 304 will effectively facilitate the installation and fixation of the ring body 301. The ring body 301 and the mounting post 302 are mainly made of stainless steel, having good corrosion resistance and relatively high recycling value after being scrapped. At the same time, due to the existence of the cavity 303, the manufacturing cost is relatively low, and it is an excellent auxiliary installation structure.

[0022] Wherein, the tube body 101 is arranged on the outer surface of the intercepting part 2, and the tube body 101 is also arranged inside the ring body 301.

[0026] When using the present utility model to install the finned tube 1 and the throttling part 2 to a designated position, the installation collar 3 is used for positioning and installation. At the same time, during long-term use, the installation column 302 will effectively install the finned tube 1 and the throttling part 2. Meanwhile, the cavity 303 will be filled with inert gas, thereby maintaining a long service life. At the same time, the chamfered groove 304 will effectively facilitate the installation and fixation of the ring body 301. The ring body 301 and the installation column 302 are mainly made of stainless steel, having good corrosion resistance and relatively high recycling value after being scrapped. At the same time, due to the existence of the cavity 303, the manufacturing cost is relatively low, which is an excellent auxiliary installation structure.
