Zhang, Z.; Han, T.; Zhang, H., and Yu, X., 2019. Heat transfer model of miniature heat pipe embedded in marine cabinet. In: Hoang, A.T. and Aqeel Ashraf, M. (eds.), Research, Monitoring, and Engineering of Coastal, Port, and Marine Systems. Journal of Coastal Research, Special Issue No. 97, pp. 103–106. In order to ensure the reliable work of electronic components in the marine cabinet, electronic equipment should be placed in a closed cabinet to prevent damage by sea dust, corrosive gases and rainwater. In this paper, based on the working principle of embedded miniature heat pipe, a heat transfer model of embedded miniature heat pipe based on irregular cross section is proposed to replace the traditional heat transfer device and solve the heat transfer problem in the marine cabinet. The heat pipe structure is analyzed and the heat capacity and thermal resistance network method is used to solve the thermal problem of the marine cabinet. Based on the analysis of heat transfer network of marine cabinets, the heat transfer model of embedded miniature heat pipes is established by dividing the nodes of heat pipes. According to the number of axial nodes of the heat pipe, the heat transfer power of the heat pipe is solved. The experimental results show that the heat resistance of the miniature heat pipe embedded in the marine cabinet can be divided into the cooling thermal resistance and the cyclic thermal resistance, in which the proportion of the cooling area and the length of the cooling section to the total length is the main factor affecting the cooling thermal resistance. Heat source temperature and liquid filling rate are the main factors affecting the thermal resistance. The cooling temperature has little effect on the heat transfer resistance. The heat transfer power can be improved by increasing the cooling area, length ratio of cooling section, cooling flow rate, heat source temperature and filling rate as well as reducing the cooling temperature. The first 3 factors are the best way to improve the heat transfer power.
