Based on the deep research of structure characteristics of the shell-side of the shell-and-tube heat exchanger and laws of fluid flow and heat transfer, the concept of "sideling flow" in the shell-side is presented for the first time, which is relative to the flow states of the cross-flow, the longitudinal-flow and the helical-flow.

在上述壳程流体&斜向流&状态理念的指导下，首次研制开发了新型高效节能管壳式换热器—帘式折流片换热器，改进和发展了换热器壳程的结构形式，实现了壳程流体的斜向流动。

The water chamber takes the shape of tilting cube, in favor of uniform distribution of cooling water on tube plate surface. The tube bundle is divided into two groups of zygomorphy according to the bisection system and it has eight support clapboards. The siphonopore center of each clapboard increases a certain distance corresponding to that of two tube plates and the cooling tube takes the shape of arch. The two-way cooling water of bisection flows through the condenser in opposite direction so as to improve the distribution of heat load for tube bundle. Around the throat of condenser, the final stage low-pressure heater, air extraction tube, intake device of bypass exhaust and the like are deployed.

它的特点是：水室呈倾斜立方体形状，有利于冷却水流在管板面上均匀分布；由于采用对分制，管束相应地分为左、右对称的两组，并且管束设有八块支撑隔板，每块隔板的管孔中心相对于两端管板的管孔中心依次抬高一定的距离，以使冷却管呈拱形状；对分制的两路冷却水以相反方向流过凝汽器，从而改善管束的热负荷分布；在凝汽器喉部布置了末级低压加热器，抽汽管道及旁路排汽接受装置等。
