impingement plate, longitudinal baffle, sealing strips, supports, and foundation.
The Standards of the Tubular Exchanger Manufacturers Association (TEMA) (1)describe these various components in detail.
An STHE is divided into three parts: the front head, the shell, and the rear head. Figure 1 illustrates the TEMA nomenclature for the various construction possibilities. Exchangers are described by the letter codes for the three sections —for example, a BFLexchanger has a bonnet cover, a two-pass shell with a longitudinal baffle, and a fixed-tubesheet rear head.
Classification
based on construction
Fixed tubesheet. Afixed-tubesheet heat exchanger (Figure 2) has straight tubes that are secured at both ends to tubesheets welded to the shell. The construction may have removable channel covers (e.g.,AEL), bonnet-type channel covers (e.g.,BEM), or integral tubesheets (e.g.,NEN).
The principal advantage of the fixed-tubesheet construction is its low cost because

打击碟子，纵观的助声器,封闭长条，支持和基础。
管状的交换器制造业者协会 (TEMA)(1) 的标准详细地描述这些各种不同的成份。
STHE 被区分为三个部份: 前面的头，贝壳 , 和后面的头。 图 1 为各种不同的建筑可能性举例说明 TEMA 命名法。交换器对于三个区段被信描述密码 -举例来说， BFLexchanger 有软帽掩护,一二-途径以纵观的助声器 , 和固定- tubesheet 后面头去壳。
分类
基于建筑
固定的 tubesheet。 Afixed-tubesheet 热交换器 (图 2) 有在 tubesheets 焊接到贝壳的两者结束 被保护的直管。 建筑可能有可移去的频道掩护 (举例来说,AEL) ，软帽- 类型频道掩护 (举例来说,BEM), 或整体 tubesheets.(举例来说,NEN)
固定- tubesheet 建筑的主要利益因为它的简单建筑是它的低点费用。 事实上，固定的 tubesheet 是最没有贵的建筑类型,只要没有扩充关节被需要。
因为不准装凸缘关节，其他的利益是，管能被在频道掩护或软帽的移动之后机械地清理，而且 shellside 液体的那一个漏被减到最少。
这设计的缺点是，因为捆被修理到那
去壳并且不能够被移动, 那在管的外面不能够被清理
机械地。 因此，它的申请被限制清理在贝壳上的服务-边。 然而，如果一个满意的化学清洁计画能被雇用,固定- tubesheet 建筑可能被为弄脏在 shellside 上的服务选择。
