Abstract

The invention provides a design method of a vertical finned tube type heat exchanger. The design method comprises the following steps: a, determining the total heat exchange amount of the vertical finned tube type heat exchanger; b, determining a total heat exchange area according to the total heat exchange amount; c, determining the arrangement mode of vertical fin heat exchange tubes of the vertical fin tube type heat exchanger according to the total heat exchange area; d, determining the air side heat transfer coefficient and the resistance coefficient of the vertical finned tube type heatexchanger through experiments according to the total heat exchange area of the vertical finned tube type heat exchanger, the determined parameters of the vertical finned tube type heat exchanger in the arrangement mode and the air flowing direction; e, checking and calculating the heat exchange area and the resistance coefficient of the vertical finned tube type heat exchanger according to the airside heat transfer coefficient and the resistance coefficient; and f, shaping the vertical finned tube type heat exchanger according to the checking calculation result so as to obtain a shaped product.

Description

technical field [0001] The invention relates to the field of fast reactor accident waste heat discharge, and more specifically, relates to a design method of an air heat exchanger. Background technique [0002] At present, the basic principle of passive waste heat removal is natural circulation, that is, the use of fluid gravity, inertia, natural convection, diffusion, evaporation, condensation and other principles to remove waste heat from the core under accident conditions. The setting of the corresponding system can simplify the special safety facilities, reduce equipment and components, reduce possible misoperations caused by personnel intervention, improve the relationship between man and machine, and improve the inherent safety of nuclear power plants. Therefore, technically speaking, passive technology is an advanced safety technology at present and represents the development trend of a new generation of nuclear power. [0003] In order to meet the passive requiremen...
