Description

具有碳素钢换热片并利用镀锌焊接的椭圆形热管
本发明总的涉及生产过程中的热交换，尤其涉及一种新颖实用的热管结构。
热管在热交换领域中是众所周知的。热管通常呈圆筒形，并具有圆形截面。在各端上设有盖件以构成一封闭管体(vessel)。贯穿该管的中心设有一芯体(wick)。工作液位于热管管体的内部。
热管的一端是蒸发端，它暴露于诸如热空气之类的温热物质中。另一端是冷凝端，它暴露于较冷物质中。蒸发端的热量使工作液蒸发并流至热管的相对端、即冷凝端。在冷凝端上，工作液将热量排放至热管物质，与较冷物质换热，并凝结成液体，而后，借助芯体作用又流回至蒸发端，从而重复该循环。在适当选择工作液的情况下，以这种方式即可在温差相对较小的物质之间、也可以在那些温差较大的物质之间高效地传递热量。
已知将非圆形管用于热交换器中。然而，热交换器管不同于热管，即它们缺少热管的内部结构，并且不能用作为自备式换热系统。尤其，以往的设计不太适宜包含芯体，而芯体对于热管而言是必不可少的元件，并且需要它起作用。
例如，美国专利5,279,692号揭示了一种椭圆形管，它具有贯穿该管的几个分离的、总的呈三角形截面的流动通道。
使用在具有截面加强件的锅炉及熔炉中的非圆形截面管是已知的。美国专利5,511,613号揭示了一种使用在锅炉热交换器中的非圆形截面管。该管在其内部可具有截面加强件。这些加强件的形状各异，并在管的内部形成节流挡板。
椭圆形管尤其具有有利于用作为热管管体的性能。提供了较大的表面积以供冷凝之用。还提供了较窄的宽度以使在热管蒸发端内呈液态的工作液汇集并使其量最小化。
本发明的目的在于提供一种具有非圆形截面以利用不同截面的热管。
因此，本发明提供了一种具有椭圆形截面的热管。换热片在冷凝端安装在热管上。这些换热片是镀锌焊接(galvanize)到热管上的。间隔片可用于支撑换热片并使其相互隔开。在热管内可设置内部间隔件，用以支撑用于较长热管的热管结构。
体现本发明特征的多个新颖的特点详细具体地罗列在附加的、并构成一部分内容的权项之中。为了更好地理解本发明、其操作优点以及通过它的使用所获得的特定目的，请参阅说明本发明一较佳实施例的附图及其描述内容。
在附图中：
图1是本发明一种热管的端横剖面视图；以及
图2是本发明一种热管的右侧端部立体图。
现在请参阅附图，图中相同的标号用于表示相同或类似的元件，图1示出了本发明一种热管10的椭圆形截面。该热管10包括有具有非圆形截面的一管体30。在该管体30之中可设置一内部支撑件25，以便在诸如当热管10较长时支撑该管体30。支撑件25可为延伸在管体30的两个内侧壁之间的一平面段件。
热管10的内腔还包括环绕管体30的内腔壁的一芯体20，该芯体将工作液(未图示)在热管的冷凝端与蒸发端之间输送。
工作液在蒸发端被加热及蒸发，并流经管体30的中心流至冷凝端，在那里，热管10外部的较冷物质使工作液凝结。该工作液被芯体20吸收，并借助该芯体的作用又朝着蒸发端回移。
管体30的椭圆形截面为热管10提供了较大的换热表面积。另外，工作液在热管10的蒸发端内汇集且使其量最小化。这些改进增加了热管10在各端物质之间传递热量的效率。
图2示出了整条热管10，它具有蒸发端盖40、冷凝端盖50和换热片60。该换热片60可具有片间隔件65，这些间隔件接近各个拐角，用以支撑诸换热片60并使其相互之间隔开。该换热片60较佳地由碳素钢制成，以使它们可通过镀锌焊接到热管管体30的表面上。因此，管体同样较佳地由碳素钢之类的钢制成。该换热片通过延伸或增大换热表面积来提高热管10的热交换性能。
一开孔(vent)或阀45设置在蒸发端盖40上。该阀45用于对热管添加工作液。虽然该阀45如图所示位于蒸发端盖40上，但它也可设置在任一端盖40或50上。
端盖40、50较佳地由碳素钢制成，并被焊接在管体30上以形成气密密封。
虽然为了说明本发明的原理应用，图示并详细描述了本发明的一个特定实施例，但应当明白的是，在不脱离这些原理的情况下，还可以其它形式来体现本发明。
