摘    要:从换热器的传热方程和投资费用方程出发,在各种不同给定条件下,采用函数求极导出换热器两侧换热表面的最佳匹配准则关系式.在考虑投资费用前提下两侧换热表面的选择应遵循的不等效匹配原则.此外,还针对两侧助化的情况推导出最佳匹配关系式

关 键 词:换热器  换热面选择  表面最佳匹配

Abstract:On the basis of the heat transfer equation and the investment cost equation in a heat exchanger, the optimal match relations between two surfaces of convective heat transfer have been derived under different given conditions with the aid of evaluating extreme value of function. The optimal match is not equivalent effect with consideration of investment cost, and is different from the traditional equivalent heat resistance match. In addition, the optimal match rules have been obtained for the heat transfer surfaces fining two sides of a heat exchanger.
Keywords:heat exchauger  selection of courective surface  optimal match
