Research on the Flow and Heat Transfer Characteristics of a Water-Cooling Plate in a Heat Dissipation System

The water-cooling heat dissipation technology can solve the heat dissipation and noise problems of the calculation plate. Therefore, the structural design of the water-cooling plate directly affects its flow and heat transfer characteristics, which restricts the promotion and application of the technology. To this end, the water-cooling plate of a heat dissipation system was taken as the research object, and its flow and heat transfer characteristics were numerical simulated and experimental studied. Through comparative analysis, the rationality of the numerical simulation method was verified. Based on this, three improved schemes of water-cooling plate structure were proposed and numerical simulation was carried out, and the optimal model was verified by experiments. The results of the study show that compared with the original water-cooling plate, the optimized water-cooling plate has increased internal flow velocity and distributes uniformly, increased heat transfer amount by 4.2%, and the average temperature of the calculation plate decreased by 5.3%.
