Description

散热片卡接结构
                          技术领域
本实用新型涉及一种能以连续冲模方式快速将各散热片单元卡接成排的散热器,特别涉及这种散热器中散热片之间的卡接结构。
                          背景技术
对电子元器件、集成电路及微型组件进行散热是计算机以及电子设备向小型化、便携式方向发展的重要问题。近年来,由于技术进步散热器结构也相应发生了很大变化,其中具有代表性的是一种能以连续冲模方式快速将各散热片单元卡接成排的散热器。如台湾专利公报于2001年12月11日公告了一件名称为《散热片卡接结构》,公告编号为468931,申请案号为090208102,申请日为2001年5月18日的新型专利申请案。该申请的主要内容是在散热片上下端缘分别设置短折边,而在短折边的角落分别冲设勾部,并且在各短折边与散热片交接处的相关位置冲设长槽孔,从而使各角落形成能以连续冲模制成卡接结构,并使所有散热片能快而稳固的组接成排状结构。该新型专利申请案尽管与以往散热片单元之间通过凹、凸点彼此相接定位成排的散热器相比有了很大进步,但不足之处在于:1、由于勾部结构复杂,折弯方向多,相应的制造工艺复杂;2、由于勾部结构复杂,折弯方向多,相应模具结构复杂成本大;3、由于散热片展开坯料尺寸较大,材料消耗增加;4、由于勾部卡死在长槽孔中散热片排组拆卸不方便。为此,本实用新型从改进结构角度出发,提供一种简单可靠,而且更适合于连续冲模方式快速卡接成排的散热片卡接结构,以克服上述不足。
                              发明内容
为达到上述目的,本实用新型采用技术方案是:一种散热片卡接结构,每个散热片单元的两个相对侧边上分别设有折边,折边至基片的一段片体上冲设
Figure Y0226389000031
形扣位孔,该孔随折边折弯后其上端凹缺部为扣位槽,下端凸起部为扣位片,扣位槽设在折边顶部并使折边局部上凸,扣位片设在折边根部交界处的基片上并且凸起部朝外,扣位槽与扣位片位置对齐,宽度匹配;本单元扣位槽与前一单元扣位片结合,本单元扣位片与后一单元扣位槽结合,各单元彼此前后叠加卡接成排。
上述技术方案中的有关内容和变化解释如下:
1、所述“散热片单元”是指重复出现的而且结构相同的基本散热片结构。所述“基片”是指散热片除折边以外的主体部分或主片体。
2、上述技术方案中关于卡接结构的数量设置问题,可以在散热片单元每侧设置一对、两对或三对及三对以上,也可以在散热片的一侧设置奇数,而在另一侧设置偶数,但其中比较好的做法是在每侧相隔设有两对或三对扣位槽和扣位片。如果在散热片每侧设置两对扣位槽和扣位片,一般情况下采用相隔对称设置的方案;如果在每侧设置三对扣位槽和扣位片,一般通常采用左、中、右布置的方案。
3、上述技术方案中关于折边结构通常可以有下列两种做法,一种是散热片两个相对侧边上的折边均为整条结构,这种形式适合于强制通风的散热;另一种是散热片两个相对侧边上的折边中一条为整条结构,另一条为局部折边结构,这种形式适合于普通散热器,整条折边通常与热源接触,这样可以增加接触面,而局部折边的作用只是提供卡接结构。
上述内容和变化均包含在本实用新型要求保护的范围之内。
本实用新型工作原理是:采用
Figure Y0226389000041
形冲压孔通过折弯在折边处形成一对扣位槽和扣位片,然后利用前、后散热片上扣位槽与扣位片的位置关系,在连续冲模配合下直接将各散热片连续卡接成排。整个冲压组装的动作过程为:冲定位孔→冲扣位孔→外形下料→扣位凸缘折角→折边成型→卡接组装。
由于上述技术方案运用,本实用新型与现有技术相比具有下列优点和效果:
1、本实用新型卡接结构简单,折弯方向少,因此相应的制造工艺简单。
2、本实用新型卡接结构在制造上只要6个动作,而现有技术至少需要8个动作。
3、由于卡接结构相对简单,相应的模具也比现有技术采用模具简单,因此可以相应降低模具成本。
4、在外形尺寸相同的条件下,由于本实用新型散热片展开尺寸小于现有技术散热片,因此节省材料。
5、本实用新型卡接结构不仅连接可靠,而且拆卸更方便。

实施例三:一种散热片卡接结构,每个散热片单元的两个相对侧边上一条为整段折边2结构,另一条为分开的两段折边2结构,其中整段折边2上相隔设有两对扣位槽3和扣位片4,分开的两段折边2上分别设有一对扣位槽3和扣位片4。其它与实施例一相同。
