摘要：
As the energy problem becomes more and more prominent, it is urgent to develop high-efficient energy equipment. Microchannel heat exchanger has attracted much attention in thermal management system due to its excellent performance. In this paper, a calculation model is proposed for the theoretical calculation of flow and heat transfer characteristics of microchannel heat exchanger. Based on the establishment of experimental database of literature, 10 and 6 kinds of heat transfer and flow calculation correlation formulas are compared and analyzed respectively. And numerical simulation and model solving research are carried out for a heat exchanger structure. The empirical solution of heat transfer characteristics obtained by using the correlation formula proposed by Stephan et al. and Sarmiento et al. is in good agreement with experimental solutions. The empirical solution of flow characteristics obtained by using the correlation formula, which are proposed by Kim et al., Muzychka et al., is in good agreement with the experimental solution. The numerical simulation and model calculation of the heat exchange unit are carried out, and the error of most points in the numerical solution and the empirical solution is within 10%, which verifies the accuracy and reliability of the calculation model proposed in this paper in the theoretical solution. © 2022 Chemical Industry Press.
