Aluminum Profile Process: the Production and Processing Process and Technology of the Multi-flat Flat Channel Using the Aluminum Profile Flat Pipe-WJW Aluminum

Multi -hole flat channels use the production processing process and technology of aluminum profile flat pipes

The research of the air -conditioning control system mainly includes the following four major component structures, namely compressors, condenser, throwing and expansion mechanisms and evaporators. The two-sided aluminum plate of the whole aluminum home, and the PVC plate core filled in the middle of the PVC board is usually about 1.4-1.8 density values (the smaller the density value, the better the quality). Top ten brands of aluminum and products made by other alloy elements. It is usually made into a casting product, forging products, as well as foil, board, band, tube, stick, profile, etc., and then made by cold bending, sawing, drilling, assembly, coloring and other processes. The main metal elements are aluminum, which adds some alloy elements to improve the performance of aluminum. The material of the doors and windows and doors and windows is connected to the wall. The main feature is that the surface of the wall is mostly plane, and it cannot be moved on the wall. The condenser and evaporator are collectively referred to as heat exchangers. They are the heat exchange unit in the refrigeration and air -conditioning technology equipment, which plays a vital role in the performance of the entire Chinese air -conditioning product.

With the rapid development of the air -conditioning industry, it is efficient, compact, and new -type thermal demand for energy -saving. In particular, because the fatal defects of HCFC -based refrigerant -based refrigerants will be replaced, and when new working pressure such as carbon dioxide alternative refrigerant, the heat exchanger needs sufficient pressure to resist.

Multi -channel parallel flow heat exchange technology has the characteristics of more compact economic structure, light weight, high heat exchange efficiency, and strong pressure resistance. It has become the main form of heat exchanger in my country that has more market development research prospects. The parallel flow heat exchanger consists of a porous flat tube and a ripple -patterned louver wing piece. It has a flow pipe at both ends of the flat porous flat pipe of the porous aluminum profile. Social trend, this variable process optimization design method can make the effective control volume efficiency of the heat exchanger scientifically, reasonable development and utilization, and improve heat exchange capacity.

The shape of the flowing channel of the flat -porous aluminum tube is mainly rectangular and round. Due to the size of the flow tract less than 3mm, the scale effect of the two phases flowing and heat transfer of gas fluids will occur . In order to improve the heat transfer capacity of the heat exchanger and reduce the weight, the equivalent diameter of the porous flat pipeline is getting smaller and smaller, and even Reach the micro -channel level of the AMM. Figure 3 illustrates the development trend of porous flat pipes. At present, foreign abroad has been able to produce a fourth -generation aluminum profile with a thickness of 1mm and an equivalent diameter of the flow tract. The porous flat tube is squeezed by the fourth -generation aluminum profile, and my country is trying to develop the fourth -generation micro -channel porous flat tube.

2. The squeezing process of the flat pores of the pore aluminum profile

Used to generate a porous flat pipe in a parallel flow heat exchanger. During the aluminum squeezing process of aluminum squeezing by the complexity of the porous structure of the flat pipe, the general use of aluminum portholes used in the porthole of the crystal ingot is squeezed in the portholes, so as Ensure uniform wall thickness, and there is a simple production facility with low production cost. It is used to make porous flat pipes, including squeezing portholes, portholes, diversion bridges, heart shafts, and squeezing molds such as the working cavity and welding.

The flow management process of metal enterprises in the diversion mold squeezing can be divided into different diversion, welding, and forming research stages. During the diversion education stage, the materials are divided into two shares to enter a diversion hole; during the welding phase, the development of the material enters the welding room. It is integrated at high temperature and high pressure; in the stage of forming technology, the material is squeezed out of the workband after full welding room. There are many closed sections, many welded planes, and pipes are in the process of transition and pressure in the refrigeration control system. one of the reasons.
