An expression for optimal matching of performances on two surfaces of a heat exchanger is derived based on the heat transfer equation and the investment cost equation under the condition of maximum heat flow per unit cost. It is a square root law of optimal investment allocation, optimal surface distribution, and optimal thermal resistance distribution. It is shown by this law that the optimal matching of the heat transfer performances on two surfaces of a heat exchanger is not an equivalent matching owing...

An expression for optimal matching of performances on two surfaces of a heat exchanger is derived based on the heat transfer equation and the investment cost equation under the condition of maximum heat flow per unit cost. It is a square root law of optimal investment allocation, optimal surface distribution, and optimal thermal resistance distribution. It is shown by this law that the optimal matching of the heat transfer performances on two surfaces of a heat exchanger is not an equivalent matching owing to the different investment effectiveness between the surfaces. Therefore, the law given will be a good guide to the design determination of the heat transfer surfaces of the heat exchanger.

基于换热器的传热方程和投资费用方程,在单位投资费用换热热流量最大的条件下导出换热器两侧的最佳性能匹配关系式,即最佳投资分配、最佳表面积分配及最佳热阻分配的平方根律.结果表明,由于投资费用的影响,换热器两侧的最佳换热性能匹配并不是等值匹配.因此,采用该规律能避免换热器设计过程中确定换热表面的盲目性

Based on the results concerning an analysis on the equations of heat transfer and investment cost, the optimal matching between heat exchanger surface areas is further discussed. With a simple heat exchanger as an example, a quantitative analysis has been made. It is proved that the ratio between the two surface areas is inversely proportional to the root of the product of the ratio between the heat transfer coefficients and the ratio beteen the surface investment unit prices. This can be referred to as the...

Based on the results concerning an analysis on the equations of heat transfer and investment cost, the optimal matching between heat exchanger surface areas is further discussed. With a simple heat exchanger as an example, a quantitative analysis has been made. It is proved that the ratio between the two surface areas is inversely proportional to the root of the product of the ratio between the heat transfer coefficients and the ratio beteen the surface investment unit prices. This can be referred to as the optimal matching rule or the sequence root rule. Obviously, when the investment cost is taken into consideration, the optimal matching is not an equivalent one. It is the authors view that this is a challenge to the conventional viewpoint of equivalent matching of thermal resistances on the two sides of the heat exchanger.

在分析换热器的传热方程和投资费用方程特性的基础上推导出两侧换热表面的最佳配比关系式,即两侧换热表面之比与换热性能比和投资费用比乘积的平方根成反比,进而在投资费用给定的条件下对传热方程求极并导出该关系式,从而证实分析的正确性.算例表明,凡满足最佳配比关系的换热器表面,其单位传热量的投资费用最省.为换热器优化设计和检验提供了理论依据.

The basic issues of impedance matching in a radio frequency discharge excited CO 2 laser are theoretically discussed in detail. A general and very applicable formula for selecting the parameters of the equivalent matching network is obtained. The results are also used to calculate the matching network parameters for other high frequency discharge excited CO 2 lasers.
