| Abstract: | The obliquity of the air exchanger equipment, the percentage of the liquid, the properties and the temperature of the liquid, the materials of the tube and so on were selected to analyze the principle of heat transfer of the equipment. The concentrated parameter and the heat resistance network analysis methods to design the heat pipe were used, and the construction parameters of the thermosyphon were optimized with the language of Matlab, so heat transfer efficiency can be exerted. After the design of heat ... |
