I believe that everyone will not be unfamiliar with the website product of finned tubes. However, whether you have a comprehensive understanding and understanding, from the current point of view, it is not yet. Therefore, based on this, the following will continue this article. A topic, so that everyone has learning content, so that they can Laser Welded Finned Tubes deepen their knowledge and understanding of this product. 1. After adding fins to the bare tube, is it a finned tube? After the light tube is equipped with fins, it is a finned tube, so the answer to this question is yes, and there is no doubt about it. However, adding fins to the air side increases the heat transfer area and increases the heat transfer. However, in some cases, there may be some problems.
How to optimize the design of stainless steel finned tube phase change heat storage
2023 / 02 / 21
Now in order to design and develop the application models and algorithms of stainless steel finned tube heat exchanger, heat exchanger and generator, finned tube heat exchanger has the characteristics of flow coupling and heat transfer. At present, the main method to improve the heat storage rate of phase-change heat storage is to understand through practice that the heat storage process of ring-shaped finned tube and obtain the phase interface of temperature field change. On this basis, the thermal conductivity affecting the finned tube is calculated and analyzed, And the heat storage rate of fin tube spacing. It provides a certain reference for the optimal design of phase change heat storage, evaluates the heat resistance and strength characteristics of different rows of tubes and different finned tubes, provides experimental characteristic curves and correlations, obtains the number of tubes and finned tubes, analyzes and discusses the influence law of spacing, and obtains useful results. In addition, analyzes and discusses the influence law of triangular corrugated finned tube spacing, and obtains useful results. In addition, the results of triangular corrugated finned tube and flat finned tube are compared, and the glass models of finned tube heat exchanger and forced convection tube are established under constant flow conditions, and the reliability of the model is verified by the experimental results. In a more realistic situation, the thermal performance of heat exchanger under glaze conditions is simulated by considering the frosting model and fan performance curve. The results show that the efficiency of heat exchanger and finned tube is
Analysis of what is included in the welding of spiral finned tubes
2023 / 02 / 03
The welding of spiral finned tubes generally adopts high-frequency welding, so what knowledge does it contain? What can we learn from this knowledge? For those who want to understand the knowledge of finned tubes, it is also a question to think about during the learning process. Below, let's take a closer look, just for reference. 1. Welding principle The High Frequency current is used as a heat source to heat the contact surface and the area to be welded, and at the same time, an upsetting force is applied to the outside of the Finned Tube to achieve solid-phase welding of the contact surface. 2. Preparation before welding (1) There should be no obvious pits on the surface of the pipe material, and sandblasting should be carried out to remove oil, rust and other dirt. (2) The preparation of the top forging wheel should ensure that its clamping of the steel strip is moderately tight and uniform in the circumferential direction, and that the inner parts can rotate flexibly. (3) The welding between the electrode body and the contact should be firm and reliable, the cooling should be smooth, and there should be no leakage. 3. Welding parameters It mainly includes the tensile strength of welded joints, welding rate, etc. The indicators of these parameters must meet the standards stipulated by the state, such as Q/SH.MM.25-2000, etc.
