椭圆热管冷油器的设计

Design Investigation in Elliptic Heat Pipe Oil Cooler

传统间壁式冷油器在冷却重油时因为壁温过低 ,重油粘度太大而达不到设计要求的冷却效果 ,限制了重油在电厂的使用 ,而用热管做传热元件构成的冷油器能显著提高换热壁面温度 ,又能达到要求的冷油效果 ,具有节能、节水、节约轻油、系统简单、运行可靠的特点 ,颇具推广应用价值。图 2表 2参

Because of low wall temperature and high viscosity in cooling mazout, the traditional oil cooler can not be cotent with the cooling, effects designed. The usage of furnace oil is limited in coal fired power plant. The tested data show that the heat pipe oil cooler can remarkeablely rise the temperature of the heat exchange wall, can achieve the cooling effects designed, and has the advantages of energy saving, less water consumption, economizing on light oil, and system simply, and work dependable. It will have a bright application. Figs 2, tablets 2 and refs 6.
