Numerical Analysis and Optimization of Heat Dissipation of Mechanical Automation Equipment Based on Thermal Model

Abstract

If the internal heat of mechanical automation equipment exceeds or does not reach the thermal equilibrium temperature range, it will adversely affect the operational reliability, environmental protection and production efficiency of the equipment. To tackle the problem, there has been some research on the internal heat dissipation of mechanical automation equipment, but mostly of the existing studies have simply aimed to change the parameters of the cooling system, and little has been done on the loading process and implementation details of the thermal model. Therefore, this paper provides numerical analysis and optimization of the space heat dissipation of mechanical automation equipment based on a thermal model. First, the heat dissipation mechanism of mechanical automation equipment was elaborated in detail, and the structure of the cooling system for mechanical automation equipment was given. Then, a spatial thermal model of mechanical automation equipment was established, and the heat dissipation design process of mechanical automation equipment was given. After that, the differences between the natural convection heat dissipation in large space and that in confined space inside mechanical automation equipment were explored. The experimental results verified the effectiveness of the numerical simulation model proposed in this paper.
