摘要
Abstract
A unified cooling system loop suitable for multiple operating modes is established in this paper.The switching of loop operating modes is realized by controlling the state values of thermal resistance,and simulation analysis is carried out for the multi-mode engine cooling system loop coupled with phase change heat storage.The results show that placing thermal resistance nodes at specific positions before each component and on the branches enables the loop to freely switch among five operating modes.Introducing the heat storage module can reduce the heat dissipation load of the radiator.When heat storage reached its maximum,the series-connected heat storage module is reduced the engine temperature from 118 ℃ to 115 ℃,and the parallel-connected heat storage module is reduced the engine temperature from 118 ℃ to 111 ℃.The parallel connection of the heat storage module is more effective in reducing the heat dissipation load of the radiator,and at the same time,it brings a more significant temperature rise of the heat storage module.The maximum temperature difference of the heat storage module when working in series and parallel is 19 ℃.关键词
