In view of the deviation between the actual heat transfer performance and the theory of printed circuit plate heat exchanger due to processing errors and deformation during service, the shape characteristics of the actual micro-channel were measured and obtained by using ultra-depth of field microscope technology. The micro-channel heat transfer with different channel shapes was numerically simulated, and the influence of channel shape on thermal performance was analyzed. According to the results of numerical simulation, a new heat transfer characteristic correlation formula was obtained, which can provide a theoretical basis for evaluating the heat transfer performance of the actual service of supercritical carbon dioxide printed circuit plate heat exchangers.

针对印刷电路板式换热器由于加工误差以及服役过程中变形导致的实际换热性能与理论存在偏差问题,利用超景深显微镜技术,测量获取了实际微通道的形状特点,对不同通道形状的微通道换热进行了数值模拟,分析了通道形状对热工性能的影响,综合考虑物性变化、通道形状变化的影响,根据数值模拟结果获得了新的传热特性关联式,可为评估实际服役的超临界二氧化碳印刷电路板式换热器的换热性能提供理论基础。

针对印刷电路板式换热器由于加工误差以及服役过程中变形导致的实际换热性能与理论存在偏差问题,利用超景深显微镜技术,测量获取了实际微通道的形状特点,对不同通道形状的微通道换热进行了数值模拟,分析了通道形状对热工性能的影响,综合考虑物性变化、通道形状变化的影响,根据数值模拟结果获得了新的传热特性关联式,可为评估实际服役的超临界二氧化碳印刷电路板式换热器的换热性能提供理论基础。

印刷电路板式换热器  /  超临界二氧化碳  /  通道形状  /  传热关联式

In view of the deviation between the actual heat transfer performance and the theory of printed circuit plate heat exchanger due to processing errors and deformation during service, the shape characteristics of the actual micro-channel were measured and obtained by using ultra-depth of field microscope technology. The micro-channel heat transfer with different channel shapes was numerically simulated, and the influence of channel shape on thermal performance was analyzed. According to the results of numerical simulation, a new heat transfer characteristic correlation formula was obtained, which can provide a theoretical basis for evaluating the heat transfer performance of the actual service of supercritical carbon dioxide printed circuit plate heat exchangers.
