Fin pressurization is a processing technique for finned heat exchangers, mainly by applying pressure on the surface of the fins to form a corrugated shape, in order to increase the contact area between the fins and air and improve heat transfer efficiency.
The basic principle of fin compression is to compress air through a compressor, and then spray it onto the surface of the fins at a very high speed through the nozzle of the compressor, forming a corrugated shape on the surface of the fins. This process can increase the contact area between fins and air, improving heat transfer efficiency. Meanwhile, due to the presence of corrugated shapes, air will generate turbulence effects when passing through the fins, which is beneficial for heat exchange between the air and the fins.
The fin pressurization process has many advantages. Firstly, it can significantly improve the heat transfer efficiency of finned heat exchangers. Secondly, due to the wavy shape formed on the surface of the fins, the air flows better when passing through the fins, reducing the resistance to air flow and lowering the energy consumption of the fan. In addition, the fin pressurization process can also improve the compression resistance and corrosion resistance of the fins, extending the service life of the heat exchanger.
When performing fin pressurization, the following points should be noted. Firstly, it is necessary to choose a suitable compressor and nozzle to ensure that the speed and pressure of the compressed air meet the requirements. Secondly, the appropriate nozzle and spray angle should be selected based on the material and thickness of the fins to avoid excessive impact or damage to the fins. Finally, stable speed and pressure should be maintained during the operation to ensure the quality and heat transfer efficiency of the fin surface.
In summary, fin pressurization is an effective processing technique that can improve the heat transfer efficiency and service life of fin heat exchangers. In practical applications, it is necessary to select appropriate parameters for the charging machine and nozzle according to the specific situation to ensure the best heat transfer effect.
