Abstract:
In order to solve the overheating of micro-compressor cylinder cover, a numerical model to compute airflow field and temperature field is set up according to the theory of fluid-solid coupled heat transfer. A numerical model of axial-flow fan is also set up. The numerical simulation results show that the airflow channel design of the original micro-compressor is unreasonable, and the reflow of cooling air at motor frame is severe which affects the cooling performance of cylinder cover. By changing the blowing direction of the axial-flow fan, the problem of cooling air reflow is solved. Also, by optimizing the size of outlets and the parameters of the fan, the flow of cooling air is increased. Through these measures, the flow of cooling air is increased from 13.55 g/s to 23.51 g/s, and the temperature of cylinder is decreased from 388.9 K to 362.9 K. Thus, the overheating of micro-compressor cylinder cover is solved.
