Through the exergy analysis and calculation of the ice cube machine system,the energy consumption of each part was studied.For the evaporator with the high exergy loss rate,the honeycomb plate heat exchanger was proposed for optimization.Based on the CFD fluid numerical simulation method,and used the Mixture-model to simulate the phase change,The effects of multiple structural parameters such as solder joint diameter,solder joint pitch and plate spacing on evaporator performance were investigated.Finally,according to the research results,the optimal design of ice machine evaporator for honeyco...
