摘要：空气压缩机是气动系统的核心设备机电引气源装置中的主体，它是将电动机的机械能转换成气体压力能的装置，是压缩空气的气压发生装置。空气压缩机是工业现代化的基础产品，随着全球经济一体化的不断深入、科学技术的迅猛发展，空压机的使用越来越广泛，应用于机械，电子化纤，生物医药，食品，钢铁，石化，新能源等行业。但是，在使用空压机的时候，也产生了许多的问题，其中最主要的就是空压机的通风散热问题。空压机可以提供压力波动不大的稳定气流。具有转动平稳、效率高的特点。在运行时将工作气体压缩、输送及其膨胀，在此过程中会产生大量的热量，压力越高，产气量越大，产生的热量也越高。如不能把这些热量及时带走，将会由于空气温度过高而造成空压机工作效率降低、停机、甚至造成设备损坏、电机烧毁等事故。因此，要对空压机的散热通风引起高度警惕，有必要对空压机的安全通风散热进行研究。62187

本文采用流体动力学CFD模拟软件，数值模拟的方法，为研究合适的排风口位置对空压机的通风效果，本设计采用自然通风和机械通风相结合的形式，排除在空压机中散发出来的热量。

Based on the numerical simulation of air compressor cooling ventilation ICEM modeling Fluent safety design

Abstract: The air compressor is the main body of the core equipment of the pneumatic system. It is a device that converts the mechanical energy of the motor into the gas pressure energy. Air compressor is the basic products of the industrial modernization, with the rapid development of the deepening of the global economic integration, science and technology, air compressor is used more and more widely, used in machinery, electronic chemical, biological medicine, food, iron and steel, petrochemical, and other new energy sources industry.

However, in the use of air compressor, also produced a lot of problems, the most important is the air compressor ventilation cooling problem. Air comThe air compressor is the main body of the core equipment of the pneumatic system. It is a device that converts the mechanical energy of the motor into the gas pressure energy. Air compressor is the basic products of the industrial modernization, with the rapid development of the deepening of the global economic integration, science and technology, air compressor is used more and more widely, used in machinery, electronic chemical, biological medicine, food, iron and steel, petrochemical, and other new energy sources industry. pressor can provide stable flow of pressure fluctuations. With a stable rotation, high efficiency characteristics. At run time will work gas compression, transmission and expansion, in this process will produce a lot of heat, the higher the pressure, the greater the gas production, the higher the heat generated. If the heat can not be taken away in time, will cause the air temperature is too high, resulting in air compressor operating efficiency is reduced, down, and even cause damage to equipment, motor burning and other accidents. Therefore, it is necessary to study the safe ventilation and heat dissipation of air compressor in the air compressor.

This paper makes use of fluid dynamics simulation software of CFD, numerical simulation method, for the study on the suitable position of exhaust outlet of air compressor ventilation effect. This design adopts natural ventilation and mechanical ventilation combined form, excluding in air compressor radiates heat.
