Abstract

一种流道内外同时冷却的高效热交换器特征是载热流体经导流管实现热交换，通过设置于管外的散热片散热。同时在导流管内与导流管同轴设置有外径小于导流管内径的冷却管。使用加压的冷却流体对导流管内的载热流体同步实现热交换。由于采取上述设计方案使换热器获得热交换效率的提升，适合要求热交换效能很高的领域；尤其是针对瞬时热峰值很高的场合，例如电子系统、激光系统等应用。

Description

一种流道内外同步冷却的高效热交换器
技术领域
本设计涉及一种热交换器，可以实现流道内外同步对载热流体实施冷却的热交换器。
背景技术
目前，公知的热交换器；例如汽车水箱类型的热交换器，它是用多条断面为矩形的导流管分别并联导通于汇流室相邻两导流管外壁之间焊接有金属散热片，另外一种有代表性的结构是在空调上使用的盘管式热交换器，它的结构是多条圆形 管道平行排列，管道两端由专用弯头将管道 依次焊接成一条流体通路，金属管道外面无间隙串挂多片垂直于管路并相互平行的散热片，用于增加换热面积。以上两种最常用的热交换器都是利用固定在管道外边的散热片实现外部散热。
发明内容
本设计的目的是提供一种可以实现对导流管内流动的载热流体内外同时实施冷却的热交换器，能实现比较高的热交换效率。
本设计的目的是这样实现的：多条平行设置的载热流体导流管，管道两端分别与一个载热流体汇流腔焊接连通，加压后的载热流体通过设置在载热流体汇流腔上的管接头实现流动通过载热流体导流管，把热量传递给载热流体导流管，载热流体导流管外面无间隙串挂多片垂直于管道并相互平行的散热片。利用流动的气流实现散热。
在载热流体导流管内同轴设置有外径小于载热流体导流管内径的冷却管，冷却管两端分别穿过一个载热流体导流管汇流腔，分别与一个冷却管汇流腔焊接连通，冷却流体通过设置在冷却管汇流腔上的管接头进入冷却管汇流腔，并分别通过冷却管，吸收载热流体导流管内流动的载热流体的热量，经另一端的冷却管汇流腔再由管接头排出。
由于采取上述设计方案使换热器获得热交换效率的提高。适合要求热交换效能很高的领域，尤其是针对 瞬时热峰值很高的场合，例如电子系统、激光系统等应用。
附图说明
下面结合附图和实施例对本设计进一步说明。
图1是流道内外同时冷却的热交换器的正面剖面原理图。
图2是图1的测视切面图。
图3是U型流道剖面视图。
具体实施方式与实施例
图1是是流道内外同时冷却的热交换器结构原理；
1、是汇流室，它是个封闭的腔体，内部设置有一个隔离板9将汇流室腔体分为两个独立腔体，分别为载热流体汇流腔4、与冷却流体汇流腔2、在汇流室外壁上分别设置有两个管接头，管接头3、与冷却流体汇流腔2、连通。管接头8与载热流体汇流腔4连通。
设置有多条平行排列的载热流体导流管6，载热流体导流管6两端分别与载热流体汇流腔4固定连接并导通。加压载热流体经管接头8进入载热流体汇流腔4，再通过载热流体导流管6完成热交换后流入另一端载热流体汇流腔，再经管接头流出。在载热流体导流管外平行设置无间隙固定有按一定间距排列的散热片7，可由流动的空气或流体实现散热。
与载热流体导流管6同轴设置有外径小于载热流体导流管6内径的冷却管5，冷却管5两端分别与冷却流体汇流腔2固定连接并导通。经加压后的冷却流体经管接头3进入冷却流体汇流腔2，再通过冷却管5与载热流体导流管4内的载热流体完成热交换后流入另一端冷却流体汇流腔再经管接头流出。
由图3所示为加长流道的结构；
图3中1、2、是两个独立的汇流室，分别连接一半数量的载热流体导流管及与导流管同轴设置的冷却管。管的另一端共同连通一个转向汇流室3。这样就实现了流道加长的目的。
当需要进一步加长流道时可以应用两个汇流室1、2、与多个转向汇流室3的组合实现。
