Description

Technical Field

[0001] The invention relates to the technical field of heat exchange, in particular to a grooved fin tube with the function of strengthening the heat exchange of inner and outer tubes. Background Art

[0002] With the acceleration of industrialization and urbanization, energy consumption and environmental pollution are becoming increasingly serious. Improving energy efficiency and reducing energy consumption and emissions have become major challenges faced by the world. In the process of energy utilization, heat exchange is a key link, and its efficiency directly affects the energy efficiency and operating cost of the entire system.

[0003] In the field of heat exchange technology, traditional heat exchange elements such as light tubes and spiral tubes have certain limitations in terms of heat exchange efficiency and anti-fouling performance. In order to improve the heat exchange efficiency, people are constantly exploring new heat exchange elements and heat exchange technologies. As a new type of high-efficiency heat exchange element, the grooved finned tube increases the heat exchange area and improves the fluid flow state by processing grooves and fins on the inner and outer surfaces of the heat exchange tube, thereby achieving more efficient heat transfer. The emergence of this technology not only enriches the types of heat exchange elements, but also provides a new way to improve energy utilization efficiency. Due to the presence of fins, the structure of the grooved finned tube becomes complicated, which makes it easy to deform or damage under high pressure; due to the presence of fins, the outer surface of the tube becomes uneven. Although this structure increases the heat exchange area, it is also easy to accumulate dirt and impurities. These dirt not only affects the heat transfer effect, but also may cause problems such as pipe blockage and corrosion.

[0004] Therefore, it is very necessary to propose a grooved fin tube with inner and outer tube heat exchange enhancement function in the present application to solve the problem in the background.

[0005] 1. Patent document CN104501639B discloses a non-centrosymmetric H-shaped fin tube and its fin tube heat exchange tube bundle. The above patent achieves improved overall heat exchange performance, no dust accumulation occurs on the windward side, and the total amount of dust accumulation on the leeward side is reduced. It is not only suitable for enhanced heat exchange of flue gas of fuel oil and gas, but also more suitable for enhanced heat exchange of flue gas containing ash. However, the above patent cannot realize the self-monitoring function.

[0006] 2. Patent document CN108592682B discloses a geometrically improved H-shaped fin tube. The above patent achieves that the area of ​​the windward side is larger than the area of ​​the leeward side. The specific fin front-to-back gap ratio, fillet ratio and aspect ratio can significantly reduce the dust accumulation and wear risks of the heat exchanger. It has been confirmed by experiments and numerical simulations that it can significantly enhance heat exchange while reducing flow resistance, thereby improving the efficiency and economy of equipment operation. However, the above patent cannot achieve the function of not being easily deformed or damaged under high-pressure environment.

[0007] 3. Patent document CN105737662B discloses an anti-corrosion fin tube. The above patent realizes that by setting an anti-corrosion layer, the fin tube can be prevented from corrosion during heat exchange, thereby further improving the heat exchange effect. However, the above patent cannot achieve the heat exchange enhancement function.

[0008] 4. Patent document CN103629968B discloses a stacked integrated internal and external fin heat exchange tube and a manufacturing method thereof. The above patent realizes a stacked integrated internal and external fin heat exchange tube, which is composed of a plurality of external fin units and internal fin units with a certain thickness stacked and bonded; the external fin unit includes a first annular portion and an external extension portion, and the end of the external extension portion is connected to the outer ring of the first annular portion; the internal fin unit includes a second annular portion and an internal extension portion, and the end of the internal extension portion is connected to the inner ring of the second annular portion; the first annular portion and the second annular portion are sequentially stacked into a tubular base tube of the heat exchanger. It also relates to a manufacturing method of a stacked integrated internal and external fin heat exchange tube, including stamping, stacking and sintering steps. The heat exchange tube has the advantages of both traditional external finned tubes and internal finned tubes, and the inner and outer fins are integrated with the base tube. The fin structure is compact and the fin area is large. There is no contact thermal resistance between the fins and the base tube, which greatly enhances the steam condensation and convection heat transfer performance. It can be used in energy, chemical industry, refrigeration, electronic heat dissipation and other fields, but the above patent cannot realize the self-monitoring function.

[0009] In summary, the above patents cannot achieve the functions of heat exchange enhancement, self-cleaning, self-monitoring, and the function of not being easily deformed or damaged under high-pressure environments, resulting in the fin tubes being unable to fully utilize their surface area for heat exchange, resulting in low overall heat exchange efficiency, more energy consumption, and increased operating costs. Impurities cover the fin surface to form a thermal resistance layer, which reduces the heat exchange efficiency. Failures cannot be discovered in time, which magnifies the problem. Failures may cause more serious safety problems, such as leakage, explosion, etc., posing a threat to personnel and property. To this end, the present application proposes a grooved fin tube that can achieve self-cleaning function, self-monitoring function, function that is not easily deformed or damaged under high pressure environment, and function of enhancing heat exchange between inner and outer tubes.

During the whole process, the pressure sensor 24 and the stress sensor 25 monitor the working status of the system in real time and transmit feedback information through the data line. The magnetic pole disk 40 automatically adjusts the distance between them according to the sensor data to ensure that the system responds to the external pressure in a timely and accurate manner.

The sample feed strip 33 is responsible for analyzing the components of the sample in the waste bag 35 or the collection tray 27 through the mass analysis element 31. In this process, the fixed connection of the sample feed strip 33 to the digestion element 34 and the collection tray 27 ensures the accuracy and integrity of the sample.

At the same time, the fluctuation of the micro vibrator 29 generates an adjustable flow to ensure the uniform distribution of the flow. The response point in the flow deformation corrugated circle 5 feeds back the collected fluctuation signal to the pressure sensor 24 and the stress sensor 25 to form a closed-loop control to ensure the stability and responsiveness of the system. Through the data connection, the ion inspection element 32 monitors the abnormal state of the sample in real time and returns the data to the adsorption tentacles 26 for positioning and analysis. When abnormal data appears, the control of the electric field will enable the adsorption tentacles 26 to locate specific data points for targeted processing.

[0032] Working principle: During operation, the fluid first passes through the fluid distributor 3 and is evenly distributed to the spiral fins 1 of the first enhanced tube 2. The fluid flows at a certain speed and exchanges heat through the outer surface of the spiral fins 1. During this process, the flow state of the fluid will be affected by the spoiler group 20. The spoiler breaks the laminar state of the fluid and increases the contact area between the fluid and the tube wall, thereby improving the heat transfer efficiency. After the fluid enters the No. 1 enhanced tube 2, the fluid is evenly distributed through the fluid distributor 3 to ensure that each part of the fluid can fully contact the spiral fin 1. When the fluid flows in the tube, it is affected by the spiral fin 1, and the flow state becomes more complicated, forming a stronger turbulence. When the fluid passes through the pipeline, part of the energy will be captured by the recovery component and adjusted by the control element 13 to optimize the energy efficiency of the system. The energy recovery component is connected to the fluid distributor 3 through the pressure exchange tube 14 to ensure that the energy is reasonably used. The function of the micro vibrator 29 is to generate fluctuations through unstable flow. These fluctuations not only promote the uniformity of fluid flow, but also make the flow of the fluid in the pipeline more mixed. The sensor monitors the pressure and stress changes of the fluid in real time, and feeds back the data to the control system to adjust the flow rate and flow of the fluid to ensure that the system is always in the best operating state.
