Design of a heat exchanger and temperature homogenization device for airflow in chamber

摘要

Traditional heat-exchanger can ensure the air in chamber a specific bulk temperature,but cannot guarantee the temperature distribution is even.A heat exchanger and temperature homogenization device was designed to precisely adjust the temperature and temperature uniformity of airflow.The device was made up of several parallel processing units.Each unit was an independent heat exchanger with temperature homogenization function.To improve the design of the device,evaluation indexes were proposed for both heat transfer capability and temperature uniformity of the airflow field.Analysis and comparison of 3D numerical simulations using FLUENT were made to figure out the optimal way.The model proposed can provide guidance for practical applications.The final resuhs indicate field synergy principle can be used to analyze the temperature homogenization of airflow.
