| The basic principle and the components of the liquid cooling system (LCS) have been introducedin this paper, which is based on the developments and the current technologies of the LCS. On thecondition of the current LCS technologies, a subminiature liquid cooling system is designed in thispaper based on some specific demands. Some of the LCS technologies are discussed and optimized.The design of this subminiature LCS has been controlled more strictly on its size and weight thanother LCS. So some researches and optimized technologies about system size, weight, flow ratecontrol, heating system and system control have been put into effect in this system. The details ofthese designs and the methods that used in this paper include the following aspects. First, the size andweight of each component and the whole subminiature LCS are checked. Some components areoptimized so that the system can meet the demands. Second, the traditional methods of flow ratemeasurement are analyzed in this paper. An indirect way to measure flow rate is introduced in thissubminiature LCS which includes its theory, experiment preparation and simulation. This simulationwhich is applied with Flowmaster software includes a simple model and get a conclusion that thetemperature has little affect on the pressure drop in the pipe. Third, design the flow rate controlmethods. In this paper The Gambit software is used for carving up mesh. And the post-processingsoftware to deal with data is Tecplot. The Fluent software is used in the numerical simulation of flowand heat transfer of pipes and heating of the reservoir used in this system. These simulation resultshave provided references for the designs and the way to optimize.Though the analyses of the design and technologies used in subminiature LCS in this paper, thesmaller and subminiature LCS is possible. The key problems of this design include optimizing theheat exchanger, the solution of the system air flow, development on the small or micro pumptechnology, small sensors used in flow rate measurement device and the way to measure the flow rate.Several useful methods of these problems have been introduced in this subminiature liquid coolingsystem which will be helpful for the further research on liquid cooling system miniaturization. |
