摘要
本文以系统节能和提高综合经济效益的观点，分析了金属换热器传热系数的影响因素及提高途径；气流阻力与动力消耗；传热面积与投资的定量关系。为正确选用不同结构金属换热器及其性能提供了依据。
From the points of view on saving energy systematicaliy and increasing complex economic benefits, this paper investigates the factors affecting the heat transfer coofficients of the metal-heatexchanger and its rising way, the airstream resistance and power consumption, the quantitive relationship of investment with heat transfer area, which provides a reference to chere different structure of the metal-heat-exchanger correctly.
