A microchannel heat exchanger with a triangular wave and symmetrical triangular wave structure was proposed in this paper. In addition, a new N‐type microchannel heat exchanger was developed to balance the heat transfer performance and pressure drop. The relationship between different configurations of the N structure of the microchannel and the heat transfer performance was analyzed. The results showed that, at a high inlet flow rate, the symmetrical triangular wave microchannel had the best heat transfer performance, followed by the triangular wave microchannel and the straight channel. At the same flow rate, the degree of disturbance of the fluid was highest in the symmetrical N‐structure microchannel, and an excellent heat transfer effect was observed.

N型微通道换热器传热性能的仿真分析

提出了一种具有三角波和对称三角波结构的微通道换热器。此外，还开发了新的N型微通道热交换器，以平衡传热性能和压降。分析了微通道N结构的不同构型与传热性能之间的关系。结果表明，在高入口流量下，对称三角波微通道的传热性能最好，其次是三角波微通道和直通道。在相同的流速下，对称的N型结构微通道中流体的扰动程度最高，并且观察到了极好的传热效果。
