Description

肋板式换热器 技术领域
本发明涉及一种肋板式换热器，这种肋板式换热器可以被用于制冷和热泵循环中 的冷凝器和蒸发器等换热器以及各种介质的相互换热。
背景技术
目前在介质的冷凝、 蒸发和相互换热的过程中， 经常会采用板式换热器， 构成 板式换热器的这些换热板的连接密封形式通常采用焊接或钎焊工艺以及使用胶粘或 密封垫片作为各换热板之间的连接密封形式。
SE-B-415928 公开了一种具有许多换热板的板式换热器， 每个换热板包括具有 第一角孔和第二角孔的第一端部区域、 第二端部区域和从第一端部区域向第二端部 区域延伸的中心传热区域， 中心传热区域具有波紋； 用于同一种流体入口和出口的 角孔设于换热板的同一侧，
W085/02670公幵了具有许多换热板的板式换热器， 每个换热板包括具有第一角 孔和第二角孔的第一端部区域、 第二端部区域和从第一端部区域向第二端部区域延 伸的中心传热区域， 中心传热区域具有波纹； 该中心传热区域从第一端部区域向第 二端部区域延伸； 所述用于同一种流体入口和出口的角孔设于换热板的同一侧； 第 一分配区域在第一端部区域延伸， 第二分配区域在第二端部区域延伸； 所述分配区 域中有一些按规律和排列方式凸起的包， 这些凸起的包使得换热介质在分配区域之 间的板间隙中其流阻小于在中心传热区域之间板间隙内的流阻。
上述板式换热器的不足之处在于；当各换热板被相互叠放并连接密封在一起时， 各层中心传热区域之间的支撑以及抵御工作压力等产品的机械性能是靠波纹脊线之 间有限的相互接触点和接触点之间连接物质的性质所体现的， 这些接触点的形状、 数量和分布状态不光取决于满足换热介质的需要， 还将取决于换热板所用的材料等 材料机械性能， 面对必须使用具有特殊性质的某些材质较软， 各项机械性能较低的 材料制作换热板时， 以及必须使用某些具有特殊性质的连接密封物质时， 这类板式 换热器在由波紋构成的各中心传热区域之间由于接触点较少， 将使这类板式换热器 不能满足抗破坏压力和抗疲劳寿命等各方面的使用要求。
上述这种板式换热器的不足之处还在于； 各换热板上由波纹构成的各中心传热 区域是用固定的模具液压成形的， 模具制造完成后换热板上由波紋构成的中心传热 区域的波紋分布是不能改变的， 这样的换热板在面对各种不同换热介质时只能采用 由同样的波紋分布构成的中心传热区域进行换热， 其结果当然是不能很好的满足各 种换热介质的不同换热要求， 为此现有板式换热器采用制造各种具有不同波紋分布 形式中心传热区域的换热板来面对不同换热介质的要求， 但是这将加大产品的制造 成本。
发明内容
本发明的目的是克服上述不足之处， 提供一种肋板式换热器， 它能够抵御较大 的抗破坏压力并具有较强的抗疲劳能力， 在满足不同换热需求的前提下降低换热器 的制造成本。
肋板式换热器是采用以下方案实现的：
一种肋板式换热器， 包括由肋板式换热板构成的换热芯体以及外挡板和管嘴， 构成换热芯体的这些肋板式换热板其连接密封形式采用焊接或钎焊工艺以及使用胶 粘或密封垫片作为各肋板式换热板之间的连接密封形式，在肋板式换热板上包括有； 第一端部区域， 第二端部区域和中心传热区域， 其特征在于， 肋板式换热板周边的 第一边缘区和第二边缘区为环形封闭的密封斜面， 肋板式换热板在第一边缘区和第 二边缘区之间平行于上板平面和下板平面延伸， 在肋板式换热板中第一端部区域内 有第一分配区域， 在第二端部区域内有第二分配区域， 在第一分配区域和第二分配 区域内有导流肋片， 中心传热区域在第一边缘区和第二边缘区之间从第一端部区域 向第二端部区域延伸， 在中心传热区域上有换热肋片， 在中心传热区域和第一及第 二分配区域中的换热肋片和导流肋片高度相等并与换热芯体内肋板式换热板之间的 板层流道高度相等， 中心传热区域和第一及第二分配区域为同一平面并在下板平面 高度延伸， 换热肋片与中心传热区域的平面连接并固定在一起， 导流肋片与第一分 配区域和第二分配区域的平面连接并固定在一起， 在肋板式换热板第一端部区域和 第二端部区域内有穿过肋板式换热板形成通孔的角孔， 这些角孔分别被具有上板平 面高度和下板平面高度的角孔相邻边缘区域所围绕， 这些角孔相邻边缘区域在第一 端部区域内以及在第二端部区域内分别以成组对的形式存在， 这些角孔相邻边缘区 域在第一端部区域内以及在第二端部区域内分别在上板平面高度延伸和在下板平面 高度延伸， 在这些角孔相邻边缘区域之间以及在具有上板平面高度的角孔相邻边缘 区域与中心传热区域之间包括在具有上板平面高度的角孔相邻边缘区域与第一分配 区域和第二分配区域之间有斜面过渡区域的延伸， 在上板平面高度延伸的角孔相邻 边缘区域通过斜面过渡区域与下板平面高度接触， 在下板平面高度延伸的角孔相邻 边缘区域通过斜面过渡区域与上板平面高度接触。
上述技术方案的有益效果在于：由于在肋板式换热板的第一端部区域和第二端部 区域内有分配区域并在各分配区域中有导流肋片，所以换热介质在由肋板式换热板组 成的肋板式换热器各层中心传热区域中具有较均匀的分布形态。
上述技术方案的有益效果还在于：由于换热肋片和导流肋片与肋板式换热板之间 有较大的接触和固定面积，使肋板式换热器具有较高的抗破坏压力和较好的抗疲劳能 力。
上述技术方案的有益效果还在于： 在上述的肋板式换热板以及肋板式换热器中， 换热肋片和导流肋片可以采用锯齿型、平直型、多孔型、波纹型和百叶窗型这五种肋 片类型中的一种，以及将这五种不同类型的肋片按换热介质的性质和换热要求相互组 合；由于在肋板式换热板以及肋板式换热器中的肋片形式可以按换热介质的性质和换 热要求选择不同的规格，所以同一种肋板式换热板及肋板式换热器在选用不同的肋片 形式之后可以适用于更多的换热介质和换热工况。
作为本发明的进一步改进， 在肋板式换热板上位于上板平面高度的角孔相邻边 缘区域中有一圈凹边泡， 凹边泡的底部到达下板平面高度； 在位于下板平面高度的 角孔相邻边缘区域中有一圈凸边泡， 凸边泡的顶部到达上板平面高度。
上述技术方案的有益效果在于： 由于在各角孔相邻边缘区域平面中分别添加有 均匀完整的凹凸边泡， 该均匀完整的凹凸边泡不光在产品制造过程中可以使角孔相 邻边缘区域作为密封平面相互贴紧保证密封， 在该肋板式换热器处于换热的工作过 程中， 该边泡还可以增强角孔相邻边缘区域作为密封平面的抗震和抗疲劳性能。
作为上述发明的进一步改进， 在肋板式换热板上位于上板平面高度的角孔相邻 边缘区域与肋板式换热板周边环行封闭的密封斜面之间的交界处分别设有凹坑， 凹 坑的底部到达下板平面髙度； 在位于下板平面高度的角孔相邻边缘区域与肋板式换 热板周边环行封闭的密封斜面之间的交界处分别设有凸台， 凸台的顶部到达上板平 面高度。
上述技术方案的有益效果在于：由于在各角孔相邻边缘区域平面与肋板式换热板 密封斜面之间分别添加有凹坑和凸台，该凹坑和凸台的作用可以使各肋板式换热片在 相互加紧过程中其加紧力可以连续的在凹坑和凸台之间传递，由此可以使角孔相邻边 缘区域的周边相互贴紧保证平面密封， 同时在该肋板式换热器处于换热的工作过程 中， 该凹坑和凸台还可以增强角孔相邻边缘区域作为密封平面的抗震和抗疲劳性能。
作为本发明的进一步改进,在肋板式换热板第一边缘区和第二边缘区周边环行封 闭的密封斜面直线段上设有防止该密封斜面在制造过程中变形的翻边结构，但在每个 肋板式换热板第一边缘区和第二边缘区周边环行封闭的密封斜面四个圆角处没有该 翻边结构。
上述技术方案可以使各肋板式换热板在制造过程中保持周边斜面形状不被破坏 和损伤， 同时在相互加紧以及在焊接或钎焊等连接密封过程中随着重力和夹紧力以 及密封物质的流动可以使肋板式换热板周边环行封闭的密封斜面随之产生均匀变化 并产生均匀的平行移动， 使各种密封面之间始终相互贴紧连接， 从而可以提高产品 的成品合格率。
作为上述发明的进一步改进， 在肋板式换热板上的各角孔相邻边缘区域中至少 在一个角孔相邻边缘区域内设有介质均分器， 在同一片肋板式换热板上， 具有介质 均分器的角孔相邻边缘区域内其角孔的口径小于没有介质均分器的其它角孔相邻边 缘区域内的角孔口径， 当具有介质均分器的各肋板式换热板组成肋板式换热器后， 可以使冷媒介质通过各肋板式换热板上的介质均分器被均匀的流入肋板式换热器的 各板层流道中。
上述介质均分器的设置可以是:肋板式换热板的角孔及其相邻边缘区在上板平面 高度面上，在所述相邻边缘区上设有环形凹槽， 凹槽的开口在上板平面高度面上， 凹 槽的底在下板平面髙度面上， 凹槽的边缘为弧形，在凹槽的内、外边缘上分别设有小 孔， 内、 外边缘上的小孔错位设置；
上述介质均分器的设置还可以是:肋板式换热板的角孔及其相邻边缘区在下板平 面高度面上， 在所述相邻边缘区上设有环形凹槽， 凹槽的开口在下板平面髙度面上， 凹槽的底在上板平面高度面上， 凹槽的边缘为弧形，在凹槽的内、外边缘上分别设有 小孔， 内、 外边缘上的小孔错位设置。
上述两种介质均分器可以分别单独设置在不同的肋板式换热板上， 也可以同时 设置在同一 ±夬肋板式换热板上。 当若干片带有介质均分器的肋板式换热板各自相互平面旋转 180° 叠放在一起 并连接密封构成换热芯体时，在各肋板式换^板上各自介质均分器中的角孔将叠放在 一起形成口径相对较小的角孔汇通流道，在相邻的肋板式换热板上，各内边缘上的小 孔相互对应以及各外边缘上的小孔相互对应，同时在这些肋板式换热板中没有介质均 分器的其它各角孔将形成口径相对较大的角孔汇通流道。
当两片带有介质均分器的肋板式换热板组装在一起时，第一片肋板式换热板上板 平面的顶面与第二片肋板式换热板的下板平面的背面密封连接，两个肋板式换热板上 的凹槽相对形成环形流道，被均分的换热介质将通过位于环形流道内侧的小孔流入该 环状均分流道，最后从位于环形流道外侧的小孔中流出环状流道并流向导流肋片和换 热肋片， 由此达到该换热介质被均勾分配到肋板式换热板之间各板层流道中的目的。
上述技术方案的有益效果在于： 由于在各肋板式换热板中带有介质均分器并组 成肋板式换热器， 当该肋板式换热器被用于制冷及热泵循环的换热器时， 可以使冷 媒介质通过每片肋板式换热板上的介质均分器以及均分流道被均匀的流入各肋板式 换热板之间的各板层流道中。
将若干片没有介质均分器的肋板式换热板各自相互平面旋转 180° 叠放在一起 并连接密封构成换热芯体； 或将若干片带有介质均分器的肋板式换热板各自相互平 面旋转 180° 叠放在一起并连接密封构成换热芯体； 由于在各肋板式换热板上位于 第一端部区域中上板平面高度的角孔相邻边缘区域的顶面将与紧邻的另一片肋板式 换热板上位于第二端部区域中下板平面高度的角孔相邻边缘区域的背面相互贴紧密 封， 同时在各肋板式换热板上位于第一端部区域中下板平面高度的角孔相邻边缘区 域的背面将与紧邻的另一片肋板式换热板上位于第二端部区域中上板平面高度的角 孔相邻边缘区域的顶面相互贴紧密封， 并由于各角孔相邻边缘区域具有髙低不同层 位的平面高度与肋板式换热板周边第一边缘区和第二边缘区环行封闭的密封斜面直 接相连， 当各肋板式换热板被叠放并连接密封在一起时， 将在角孔流道与中心传热 区域之间形成两倍于肋片高度的角孔流道空间， 这样的角孔流道空间将增强换热介 质在该空间的扰动和冲刷作用， 可以避免或减缓换热介质在角孔周边的滞留和沉积 杂质， 同时这样的角孔流道空间亦将有利于使换热介质均匀分配到各层中心传热区 域之中并可以降低流体的阻力。
在上述由肋板式换热板组成的换热芯体中，由于角孔通道边缘区域具有两倍于肋 片高度的角孔流道空间，使同一角孔流道中的所有空间各处压力相等，这样的压力分 布形式将有利于产品的抗疲劳性能并可以增强产品抗破坏压力的要求。
在以上所述的肋板式换热板中，在肋板式换热板上的第一端部区域和第二端部区 域内共有零至四个角孔，当各肋板式换热板按要求顺序依次叠装在一起并连接密封构 成换热芯体时，在换热芯体内各角孔由此形成角孔汇通流道并形成换热介质的单流程 或多流程。
在以上所述的肋板式换热板中， 用于同一种流体入口和出口的角孔以及围绕在 这些角孔周边具有相同平面高度的角孔相邻边缘区域将分别设在第一端部区域内和 第二端部区域内的单边同侧位置上， 形成换热介质在肋板式换热器内的单边同侧流 分布。
在以上所述的肋板式换热板中， 用于同一种流体入口和出口的角孔以及围绕在 这些角孔周边具有相同平面高度的角孔相邻边缘区域将分别设在第一端部区域内和 第二端部区域内的对角位置上， 形成换热介质在肋板式换热器内的对角流分布。
以上所述的肋板式换热器可以选用金属材料、非金属材料以及复合材料制造， 以 满足具有不同工作压力、工作温度以及具有不同腐蚀性的换热介质进行相互换热的要 求。
