Description

一种翅片及具有其的热交换器 技术领域
本发明涉及换热技术领域，具体而言，涉及一种翅片及具有其的热交换器。
背景技术
微通道换热器是一种新型高效换热器，具有传热效率高、体积小、重量轻、充注量少等优点，传统单冷型微通道换热器的翅片是通过辊轧机辊成波浪形状，然后放在上下两根扁管之间钎焊。
但由于卡槽式翅片自身结构限制，在气流动过翅片通道过程中，对于翅片前半部分，靠近扁管的两侧处，因气流与扁管和翅片的温差较大，换热较为充分；在气流中间处，距离扁管较远，气流与翅片温差较小，换热不够充分。
对于翅片后半部分，靠近扁管的两侧处，由于在前半部分充分换热，此时气流与扁管和翅片的温差减小，不能充分利用后半部分的扁管温度优势；在气流中间处，距离扁管较远，换热仍然不够充分。
发明内容
本发明的目的在于提供一种翅片，其能够通过导流结构改变风道中气流流动的路径，提高风道内气流换热的均匀性。

优选的，上述翻起部在相对于所述翅片竖直方向形成的投影与气流流向形成的夹角为B，10°≤B≤60°。
优选的，上述导流结构包括一排或多排相对垂直气流流动方向排列设置的单侧风道组，进一步的，单侧风道组由两个拱起口朝向相反的翅片切口拱起形成。
优选的，每排所述单侧风道组包括进风拱起和出风拱起；
所述出风拱起位于所述进风拱起的背风侧，所述进风拱起的拱起口和所述出风拱起的拱起口朝向相反。
优选的，上述出风拱起靠近所述扁管槽的一侧为第二背风侧，所述第二背风侧在相对于所述翅片竖直方向上的投影与所述气流流动方向形成的夹角为C，10°≤C≤60°。
优选的，上述进风拱起位于背风侧且与进风拱起切口相邻一侧位第一背风侧，所述第一背风侧相对于所述翅片在竖直方向上的投影与所述气流流动方向形成的夹角为D，10°≤D≤60°。

一种热交换器，包括翅片及扁管，所述扁管与所述扁管槽相配合。
本发明实施例的有益效果是：
相邻的两个扁管之间形成风道，气流从上风侧朝向下风侧流动，导流结构设置在风道内部，导流结构改变风道内气流流动位置，使风道内气流互换位置流动，提高了气流的换热效率，使靠近扁管的气流与扁管保持较大温差，保证了气流换热的均匀性。

结构原理：
一种翅片桥5，翅片的上风侧2开设有一个或多个朝向下风侧3延伸的扁管槽4，扁管槽4用于安装扁管11，导流结构设置在扁管槽4的两侧，翅片使用时，气流从上风侧2吹向下风侧3，导流结构沿多个不同的路径导引两个扁管槽4之间的气流，上风侧2的气流经过导流结构后，改变了气流在风道内相对流动的位置，同一股气流在上风侧2流动位置相对于下风侧3的流动位置发生了改变，在气流流动方向上，导流结构间隔设置有一组或多组；导流结构对从上风侧2流向下风侧3的气流进行多次引导换位流动。
结合图2和图3所示，气流从上风侧2流向下风侧3，扁管槽4安装扁管11，相邻的两个扁管11之间形成风道，导流结构设置在风道内，在导流结构朝向上风侧2和下风侧3的两侧分别设置有强化换热部7，强化换热部7为三棱柱状凸起，导流结构包括两个结构相同且相对于扁管槽4倾斜设置的翅片桥5。
翅片桥5分别靠近风道两侧的扁管11倾斜设置，气流可以从翅片桥5底部流动，翅片桥5包括拱起部51和翻起部52，拱起部51包括进风口和出风口，翻起部52位于出风口一侧，翻起部52位于拱起部51靠近扁管11的一侧，翻起部52用于改变拱起部51上方气流流动的位置，拱起部51背风侧在相对于翅片竖直方向形成的投影与气流流向形成的夹角为A，10°≤A≤60°，翻起部52在相对于翅片竖直方向形成的投影与气流流向形成的夹角为B，10°≤B≤60°，拱起部51和翻起部52改变气流流动方向，同时降低对气流流动产生的阻力。
如图3所述，风道内包括a和b两股气流，a气流在翅片桥5的外侧并被倾斜设置的翻起部52阻挡，从而改变了流动方向，b气流从倾斜设置的拱起部51内部流过，拱起部51改变了B气流的流动方向；翅片还设置有翻边8、定位结构9和加强筋10，定位结构9用于翅片叠装时控制片距，加强筋10用于提高翅片的结构强度。
参考图2和图3，一种热交换器，在扁管槽4内安装扁管11，相邻的扁管11之间形成风道，气流通过风道从上风侧2流向下风侧3，翅片桥5将靠近扁管11流动的气流与中间气流换位流动，翅片桥5将风道分成两部分，从翅片桥5至上风侧2，靠近扁管11的气流与扁管11充分换热，位于两侧扁管11中间的气流与扁管11换热不充分，气流流过翅片桥5，拱起部51背风侧在相对于翅片竖直方向形成的投影与气流流向形成的夹角为A，10°≤A≤60°；翻起部52在相对于翅片竖直方向形成的投影与气流流向形成的夹角为B，10°≤B≤60°，翻起部52靠近扁管11倾斜设置，靠近扁管11流动的气流通过沿翻起部52改变流动方向，相对位于风道中部流动气流通过倾斜设置的拱起部51，气流朝向扁管11流动，并贴合扁管11流向下风侧3，通过翅片桥5，将风道内靠近扁管11的流动的气流与风道内中部的气流交换，变换风道内经过翅片桥5的气流流动方向；在翅片桥5至下风侧3的风道内，靠近扁管11流动的气流为翅片桥5至上风侧2之间的中部气流，通过翅片桥5解决了风道内中部气流相对于靠近扁管11流动的气流换热不均匀的问题，使靠近扁管11流动的气流保持较大温差，提高了换热效率，同时提高了气流换热的均匀性。
实施例2：
在实施里1结构和原理的基础上，本实施例提供一种翅片及具有其的换热器，结合图4、图5所示，翅片的一端为上风侧2，翅片与上风侧2相对的一端为下风侧3，上风侧2开设有一个或多个朝向下风侧3延伸的扁管槽4。
翅片间隔扁管槽4设置有一组或多组用于引导风道内气流流动路径的导流结构，导流结构包括一排或多排相对垂直气流流动方向排列设置的单侧风道组6，单侧风道组6由翅片多个部位切割后单侧拱起形成，每排单侧风道组6包括进风拱起61和出风拱起62，出风拱起62位于进风拱起61的背风侧，进风拱起61的拱起口和出风拱起62的拱起口朝向相反，进风拱起61的拱起口朝向上风侧2，出风拱起的拱起口朝向下风侧。
出风拱起62靠近扁管槽4的一侧为第二背风侧621，第二背风侧621在相对于翅片竖直方向上的投影与气流流动方向形成的夹角为C，10°≤C≤60°；进风拱起61位于背风侧且 与切口相邻一侧位第一背风侧611，第一背风侧611相对于翅片在竖直方向上的投影与气流流动方向形成的夹角为D，10°≤D≤60°。
结构原理：
结合图4、图5所示，相邻的两个扁管11之间形成风道，风道内有a、b、c、d四股气流，均从上风侧2流向下风侧3，导流结构将风道分成两部分，导流结构至上风侧2为风道的前半段，导流结构至下风侧3为风道的后半段。
在风道的前半段，a气流和d气流分别靠近风道两侧的扁管11流动，a气流和d气流充分和扁管11进行换热，换热效率高，b气流和c气流相对a气流和d气流靠近风道的中间部位，在流动过程中与扁管11换热效率低。
单侧风道组6包括进风拱起61和出风拱起62，进风拱起61的切口朝向上风侧2，出风拱起62设置在进风拱起61朝向下风侧3的一侧，出风拱起62的切口朝向下风侧3，出风拱起62和进风拱起61在风道内倾斜设置，出风拱起62靠近扁管槽4的一侧为第二背风侧621，第二背风侧621在相对于翅片竖直方向上的投影与气流流动方向形成的夹角为C，10°≤C≤60°；进风拱起61位于背风侧且与切口相邻一侧位第一背风侧611，第一背风侧611相对于翅片在竖直方向上的投影与气流流动方向形成的夹角为D，10°≤D≤60°，进风拱起61和出风拱起62之间设置有间隙，间隙为气流流动的通道。
a气流从进风空气与扁管11之间的间隙流过，沿第二背风侧621朝向风道中部流动，b气流动过进风拱起61和出风拱起62，倾斜朝向扁管11流动，a气流和b气流动过单侧风道组6，实现了a气流和b气流在风道前半段和风道后半段流动位置的互换，在风道的后半段，b气流靠近扁管11流动并与扁管11充分换热，提高了风道内气流换热的均匀性，c气流和d气流与a气流和b气流交换位置原理相同不再赘述。
