Analysis of Industrial Air-Cooled Radiators and Research on Performance Optimization Techniques

Abstract

With the increasing power density of industrial equipment, the heat flux density is also rising, making the heat dissipation issue of electronic components increasingly prominent. Currently, air-cooled radiators and liquid-cooled radiators are the main solutions for component heat dissipation. Unlike liquid-cooled radiators, air-cooled radiators have absolute advantages such as independent heat dissipation, low cost, easy installation, and maintenance-free operation. However, compared with liquid-cooled radiators, their insufficient heat dissipation capacity is a drawback, especially the high power and high heat components. This paper studies the types of profile radiators and heat pipe radiators, analyzes the principles and characteristics of flat-fin, corrugated-fin, louver-fin radiators. It explores performance improvement methods from material, structure and technology aspects. The research shows that selecting the appropriate type and comprehensive optimization can enhance performance, and air-cooled radiators will use disciplinary integration to develop towards high-performance and intelligent directions in the future. In order to solve the above problems, based on existing research, this article first analyzes in detail the common air-cooled radiators, including their structural characteristics, heat transfer principles, and performance comparisons. Next, explore performance improvement methods from the aspects of material innovation, structural optimization and intelligent assistance.
