Description

层叠式冷却器
技术领域
本实用新型涉及一种汽车用换热设备，具体涉及一种层叠式冷却器。
背景技术
冷却器是用于冷却汽车上所有运转设备所用的润滑油，使其维持在正常温度下而持续工作，保证所有设备持续运转正常。由于汽车设计一般结构非常紧凑、轻型，这就要求冷却器在满足换热性能的前提下尽可能的降低重量和体积，由此人们设计开发了这种高效的成叠式冷却器。现有的冷却器在生产时，首先利用模具冲制相关零件，部分零件通过车床和翅片成形机加工；然后将所有零件进行超声波清洗，再利用专用夹具板装配成形，而后送入连续炉进行钎焊；最后打压检验并修补漏点。
由于现有技术中的管与上盖板的连接处采用火焰钎焊，这种方法虽然成品率很高，但是生产效率低且成本高，只适宜小批量生产；此外，所述芯片间的接触压紧依靠类似平板接触的方式，若芯片冲压成形质量差，芯片间的接触压紧在任一区域范围内出现微小间隙的话，将大大降低产品的钎接质量；芯片间无翻边台阶结构，装配时或多或少会出现装配缺陷从而影响钎接质量；外翅片采用锯齿形结构，厚度一般需达0.2mm；翅片采用冲压加工方式，使得生产效率相对较低；另外，内翅片采用打孔形结构，换热性能相对较低。
实用新型内容
本实用新型克服了上述缺点，提供了一种加工方便、生产效率高的层叠式冷却器。
本实用新型解决其技术问题所采取的技术方案是：一种层叠式冷却器，包括上盖板、下盖板、管和芯片，至少两组所述芯片层叠后设置在所述上盖板和下盖板之间，所述管固定在所述上盖板上，与芯片间形成的内腔贯通，所述两组芯片之间对应设置有翅片，所述管与上盖板之间设置有焊片，所述管、焊片和上盖板铆接固定。
所述芯片的边缘可设置有尾部结构，所述尾部结构弯曲后与相邻的芯片固定连接。
还可包括设置在所述层叠的芯片外侧的墙板，所述墙板也固定在上盖板和下盖板之间。
所述翅片可包括内翅片和外翅片，所述内翅片设置在层叠的芯片内腔，所述外翅片设置在所述层叠芯片的外壁。
所述内翅片可为锯齿形结构，外翅片可为百叶窗式结构。
所述管与上盖板连体处可设置有台阶孔。
所述芯片可采用4045与母材3A21的复合材料。
本实用新型充分利用产品需进连续炉钎焊的这一特性，利用气体保护钎焊来同样达到目的，不仅省去了火焰钎焊这一工序，降低了成本，而且缩短了制作周期，适应了大批量生产的需求。所述芯片的边缘设置有尾部结构，所述尾部结构弯曲后与相邻的芯片固定连接，可以明显改善两相邻芯片边缘相连的可靠性，使芯片的平面部分装配压紧后能有效接触，从而提高两芯片的钎接质量，有效地避免了微小间隙的出现，大大提高了成品率。并通过所述台阶孔，有效弥补了装配缺陷。
附图说明
图1为本实用新型的结构示意图；
图2为本实用新型中芯片的结构示意图。
具体实施方式
下面以TH型油冷器为例对本实用新型内容加以详细描述。如图1中所示，本实用新型主要由上盖板4、下盖板8、管1、墙板7和芯片6构成，所述芯片6为两组，分别层叠后设置在所述上盖板4和下盖板之间，所述管1固定在所述上盖板4上，与芯片6联通，所述墙板7设置在所述层叠的芯片6外侧，也固定在上盖板4和下盖板之间。所述两组芯片6之间对应设置有翅片，所述翅片包括内翅片5和外翅片2，所述内翅片5设置在层叠的芯片内腔，所述外翅2片设置在所述层叠芯片的外壁。所述内翅片5为锯齿形结构，外翅片2为百叶窗式结构。所述管1与上盖板4之间设置有焊片3，所述管1、焊片3和上盖板4铆接固定，产品钎焊前，将所述管1与焊片3、上盖板4通过夹具卡位固定并且使整体倒置(与图上形状相反)，而后利用经过表面有纹路的冲头，通过敲击管1与上盖板4连体处的台阶孔9，使两者实现有效铆接，从而使焊片3与管1、上盖板4紧密接触。由于焊片3为钎接材质，这种有效铆接必将促使产品钎焊后，管1与焊片3、上盖板4连成整体，钎接可靠。本实用新型无需采用常规的火焰钎焊，故生产效率高、成本低，并通过所述台阶孔9，有效弥补了装配缺陷。
如图2中所示，所述芯片6的边缘设置有尾部结构8，两相邻芯片颠倒放置后，通过将所述尾部结构8弯曲后与相邻的芯片6固定连接，装备时可将带有尾部结构的两芯片6通过夹具固定，利用镊子弯曲芯片6尾部，使其与另一芯片6端部相连。这样做可以明显改善两相邻芯片6边缘相连的可靠性，使芯片6的平面部分装配压紧后能有效接触，从而提高两芯片6的钎接质量，有效地避免了微小间隙的出现，大大提高了成品率。
所述芯片6采用新型的4045与母材3A21的复合材料，其延伸性能好，芯片6冲压成形后基本无裂纹缺陷，从而有效地控制了芯片6报废率。
而且，所述内翅片5设计为锯齿形结构，由于属于高换热效率翅片，故能部分提高产品的换热性能。所述外翅片2设计为百叶窗形结构，厚度仅需0.15mm，低于常规的0.2mm，降低了生产成本，减轻了重量，而且百叶窗形翅片采用专用的翅片成形机滚压加工而成，生产效率高，常规的翅片成形机一般采用冲压方式加工。
在加工生产过程中，将除外翅片2外的各零件清洗后，放入浓钎剂中浸泡并烘干，使需钎接的部分其表面包裹一层已烘干的钎剂；产品装配完毕，在产品表面均匀地喷洒浓度较低的钎剂溶液。通过连续炉钎焊，利用气体保护钎焊来同样达到目的，不仅省去了火焰钎焊这一工序，降低了成本，而且缩短了制作周期，适应了大批量生产的需求。
以上对本实用新型所提供的层叠式冷却器进行了详细介绍，本文中应用了具体个例对本实用新型的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本实用新型的方法及其核心思想；同时，对于本领域的一般技术人员，依据本实用新型的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本实用新型的限制。
