第三章单级电—温差换热器件的设计计算§3—1 元件温度场的分布及热流状态的分析目前国内外厂家所生产、使用的电—温差换热器件中,P型与N型元件大部分都是等截面的。本节以等截面元件为例,探讨电—温差换热器件在实际工作状态中,其元件内部温度场的分布情况与热流运动的规律,并据此推导一系列设计计算公式。
Chapter III Design and Calculation of Single-stage Electric-Temperature Difference Heat Exchanger §3-1 Analysis of the Distribution of Temperature Field and Analysis of Heat Flow State At present, in the electric-temperature difference heat exchanger produced and used by domestic and foreign manufacturers, P type and N type Most of the components are isosceles. In this section, the equal-section element is taken as an example to discuss the distribution of internal temperature field and the rule of heat flow in the working condition of electric-temperature difference heat transfer device, and deduce a series of design formulas.
