1-2 理想热传输装置的分解及组合为进一步对热传输装置进行理论分析,我们作如下几点假定。1.假定热传输装置中的所有组成部件厚度相同;升温器和降温器也是几何尺寸完全相同的两个全等的长方体;连接管道中与水流方向垂直的任意截面尺寸也都相同;2.假定能量只能从升温器(热源E_水)的一个侧面注入,其余三个侧面均用理想隔热材料制成,它们能
1-2 Decomposition and combination of ideal heat transfer device To further theoretical analysis of heat transfer device, we make the following assumptions. 1. It is assumed that all the components in the heat transfer device have the same thickness; the warmer and the desuperheater are two congruent cuboids with the same geometrical dimensions; the same cross-sectional dimension perpendicular to the flow direction in the connecting pipe is also the same; 2. Assumption The energy can only be injected from one side of the heat exchanger (heat source E_water), the other three sides are made of an ideal heat insulating material, and they can
