What are the advantages of CNC machining of radiator parts?

by
For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

by
Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

The oil from the upper oil collecting pipe is divided into two strands due to the internal structure of the actual heat sink

cncmachining February 08, 2022

Analyze and simulate the flow and temperature on the surface of the heat sink. The fin radiator is composed of independent parallel oil flow channels, and each channel is composed of three connected small channels. The overall film length and film width diagram is a simplified model of the fin radiator. Export the simulated data to obtain a cloud map of its temperature distribution. On the horizontal line, the viscosity increases from the middle to the two sides, and some of the viscosity increases in the longitudinal direction, which proves that the speed of the oil in the oil passage decreases from the middle to the two sides. From the figure, the temperature distribution of the oil gradually decreases from the middle oil channel to the two sides. The isotherm is a downward convex curve, and in the longitudinal direction, the temperature gradually decreases.

Infrared wall temperature analysis. Taking the infrared camera on the upper surface of the heat sink, the following figure is obtained. As can be seen from the figure, the wall temperature gradually decreases from top to bottom. On the same horizontal line, there is a trend of high in the middle and low on both sides, but slightly in the middle of * It is lower than the oil passages on both sides. This is due to the internal structure of the actual heat sink. The oil from the upper oil collecting pipe is divided into two strands, and most of it flows into the oil passages on both sides of the middle. The length of each flow channel increases from the middle to the two sides, so the resistance also increases accordingly, so such a temperature cloud picture appears. It can be seen that the simulation and experimental results are basically consistent. It can be seen from the simulation and infrared cloud chart that most of the oil flows through the middle oil passage, and the flow rate is fast. Not only the flow on both sides is small, but the large resistance leads to the slow flow rate of the oil. Although the heat dissipation capacity on both sides is good, the overall heat dissipation is not effectively. The figure and the figure are the improved heat sink shape simulation temperature distribution cloud diagram. The improved fin shape improves the overall oil flow distribution and improves the heat dissipation efficiency. Therefore, appropriately increasing the flow on both sides or shortening the length of the oil flow channels on both sides can increase the heat dissipation effect.
