一种投影机散热器及投影机 技术领域
本发明涉及机械技术领域，特别是涉及一种投影机散热器及投影机。
背景技术
图1是现有的散热器的结构示意图，如图1所示，现有散热器的两相邻安装面为一体化结构，位置相对固定，当散热器两安装面所成角度与投影机两安装面所成角度没有达到理想一致时，第二安装面打螺钉时的拉力就会影响到第一安装面的螺钉装配，导致第一安装面贴合不紧密，或第一安装面螺钉打不到位，同样造成第二安装面贴合不紧密。
现实中，由于加工误差的客观存在，两相邻安装面的相对角度不可能达到理想的一致性，当误差达到一定程度时，会在某些位置出现配合间隙过大的情况，这时处于其间的导热胶因不能紧贴，所以无法发挥有效的散热作用，而由于不能及时散热，最终会导致投影机出现投影模糊或者颜色失真的问题。

具体实施方式
为了解决现有技术中散热片与投影机装配对接不精确，从而导致投影 机散热性能下降的问题，本发明实施例提供了一种投影机散热器及投影机，通过将散热器分割为第一散热片和第二散热片，并分别置于投影机的两个安装面上，实现散热器与投影机的完全接触，从而有效防止了因散热器的散热性能下降而导致的投影机出现的投影问题。以下结合附图以及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明的技术方案，并不限定本发明的保护范围。
散热器实施例
本发明实施例提供了一种散热器，参见图2，该散热器包括：第一散热片1和第二散热片2；
所述第一散热片1和所述第二散热片2上分别设置有相互配合的插拔限位机构，所述第一散热片1和所述第二散热片2通过所述插拔限位机构可插拔连接并限位，以使所述第一散热片1和所述第二散热片2分别与投影机的相邻的两个安装面贴合；所述投影机的相邻的两个安装面之间的夹角在0到180度之间。
也就是说，本发明实施例通过将所述第一散热片1的一端与所述第二散热片2的一端设置为可插拔连接，连接后的所述第一散热片1与所述第二散热片2呈直角形，且连接后的所述第一散热片1与所述第二散热片2分别为直角形的两边，并分别固定安装在投影机的两个相邻的安装面上。
即，本发明实施例通过将现有的一体的散热器根据与投影机的两个安装面分割为两个部分，分别为第一散热片1和第二散热片2，并分别置于投影机的两个安装面上，以此消除装配过程中散热片的两个安装面(即，图1中的第一安装面与第二安装面)相互之间的相互影响，使散热器能够与投影机紧密连接，或者也可以说，本发明实施例为改善散热器与投影机的匹配问题，考虑把散热片分割为两个，分别置于X、Y方向的两个侧面，以此消除装配过程中散热器两侧面的相互影响，从而有效防止了因散热器的 散热性能下降而导致的投影机出现的投影问题。
图3是本发明实施例的第一散热片的正视图，图4是本发明实施例的第一散热片的侧视图，如图3和图4所示，本发明实施例的所述第一散热片1具体包括：第一榫槽12、第一榫头11以及第一凹槽13；
图5是本发明实施例的第二散热片的正视图，图6是本发明实施例的第二散热片的侧视图，如图5和图6所示，本发明实施例的所述第二散热片2具体包括：第二榫槽22、第二榫头21以及第二凹槽23；
图7是本发明实施例的散热器的整体结构的正视图；图8是本发明实施例的散热器的整体结构的后视图；如图7和图8所示，具体实施时，本发明实施例的所述第一散热片1和所述第二散热片2通过扣榫连接机构。
具体来说，本发明实施例的扣榫连接机构包括：设置在所述第一散热片1端部的第一榫头11和第一榫槽12，以及设置在所述第二散热片2端部的第二榫头21和第二榫槽22，具体来说，本发明实施例是通过将榫头与散热片的连接位置上设置一个榫槽，并且榫头与榫槽呈预定的的角度，以使榫头能够最后卡在对方的榫槽中；
所述第一榫头11与所述第一榫槽12呈预定角度，并且所述第二榫头21与所述第二榫槽22也呈预定角度，使所述第一榫头11插入到所述第二榫槽22内，同时所述第二榫头21插入到所述第一榫槽12内后，所述第一散热片1与所述第二散热片2的位置相对固定。
具体的，将所述第一散热片1，在与所述第二散热片2连接的一端上，设有第一榫头11，所述第一榫头11与所述第一散热片1之间设有第一榫槽11，所述第一榫槽12与所述第一榫头11呈“L”型；
所述第二散热片2，在与所述第一散热片2连接的一端上，设有第二榫头21，所述第二榫头21与所述第二散热片2之间设有第二榫槽22，所述第二榫槽22与所述第二榫头21呈“L”型；
图10是本发明实施例的两散热片连接迁移的具体结构图，通过图10可知，具体连接时，所述第一榫头11插入所述第二榫槽22内，同时，所述第二榫头21插入所述第一榫槽12内，插入后，所述第一榫头11卡扣在所述第二榫槽22内，所述第二榫头21卡扣在所述第一榫槽12内，使所述第一散热片1与所述第二散热片2位置相对固定，且插入后，所述第一榫头11与所述第二榫头21整体呈“L”型，具体如图9所示。
本发明实施例的所述第一榫头11的中心轴线与所述第一榫槽12的中心轴线相垂直；且所述第二榫头21的中心轴线与所述第二榫槽22的中心轴线相垂直。
需要说明的是，本发明实施例的所述第一榫头11与所述第一榫槽12之间设有第一凹槽13，所述第一凹槽13使所述第二榫头21能够插入所述第一榫槽12内；
所述第二榫头21与所述第二榫槽22之间设有第二凹槽23，所述第二凹槽23使所述第一榫头11能够插入所述第二榫槽22内；
具体实施时，本发明实施例通过将第一榫头11和第二榫头21的榫头设置为一斜面，并在榫头与榫槽之间的侧面上设置一个凹槽，通过上述的斜面和凹槽可以使榫头很容易的插入到对方的榫槽中。
需要说明的是，本发明实施例是将现有的整体一体的散热器的两个呈一定夹角的散热片分割为两个散热片，具体为第一散热片1和第二散热片2，用榫扣的搭接方式进行可动连接，具体形式如图7和8所示，第一散热片的端部伸出的第一榫头11搭接于第二散热片2的第二榫槽22一段斜面上，同样，第二散热片2端部的第二榫头21也搭接于第一散热片1的第一榫槽12的斜面上。两处搭接结构交错设置。装配或拆卸时，两散热片需要以一定角度接近，使搭接的榫头能够进入对方的榫槽内或从榫槽内脱出，在一定角度内榫头与榫槽形成互锁，这种情况下两散热片相对可动，但不能完 全分离。
散热片装配过程中，当第一散热片1打螺钉固定时，由于螺钉拉力使其向右运动，这时第一榫头11上的斜面有将第二散热片2向下压紧的作用；同样，当第二散热片装2打螺钉固定时，其第二榫头22也有将第一散热片1向右压紧的作用。这两个作用力互相加强，可使榫头与榫槽斜面更紧密地配合，使二者间的热传导作用更有效。由于两散热片对于对方的作用力都是集中在很小的范围内，基本不产生扭矩，从而避免了现有技术中两个散热片相互间的扭矩作用。
如图9所示，当两散热片装配完成后，第一散热片1和第二散热片2闭合在一起，且呈垂直角度。打开时，第二散热片2以O点为中心顺时针旋转到一定角度(水平位置可计为零度)，再沿第一散热片1的表面L平移到Q点(具体如图10所示)，旋转角度必须足以使第二散热片2在平移时其端部越过P点，才能使两件分开。闭合过程则与此相反，第一散热片1与第二散热片2以大于上述打开过程所必须的最小角度接近，当第二散热片2越过P、Q点位置后再进行平移和旋转，直到恢复到图9所示状态。
具体固定时，本发明实施例需要同时将两个散热片以打螺钉方式(或其他方式)装配固定到投影机上，如前面所述的散热片与投影仪装配的情形，两个散热片的装配面要求同时贴紧，并且一个散热片的装配面的装配固定不会干扰到另一个装配面的装配固定。
具体实施时，本发明实施例的第一散热片1、所述第二散热片2通过固定件固定安装在投影机的两个相邻的安装面上。
并且，本发明实施例还在所述第一散热片1与所述投影机的安装面之间，以及所述第二散热片2与所述投影机的安装面之间，均设置导热衬垫。
具体的，本发明实施例是在两个搭接面之间涂布一定量的导热脂或加贴导热衬垫，提高两部分散热片之间的热传导效率，保持两侧发热元件散 热的平衡。
需要说明的是，在具体实施时，本发明实施例的相邻两侧面的散热器有完全独立的散热片和导热热管，装配过程中两个散热片相互之间没有力的作用，装配互不干涉。
本发明实施例也可以在现有的一体的散热器基础上进行改良，通过在两侧结构中间切除掉一些材料，减小连接处的截面面积，从而减小其抗弯截面模量，达到降低刚度的效果，具体如图11所示。
本发明实施例所述的散热器至少能够带来以下的有益效果：
1.本发明实施例的散热器的两个装配面相互独立，相互间不传递扭矩作用，消除了装配过程中的相互之间的干扰；
2.本发明实施例的散热其两部分并不完全分离，在螺钉拉力作用下可互相增强与投影机装配面的压紧力，更有利于起到压紧作用，防止散热性能下降。
投影机实施例
本发明实施例提供了一种投影机，该投影机包括散热器实施例中的任意一种所述的散热器。
本发明实施例散热器的相关内容可参考其他实施例的相关内容进行理解，此处不再赘述。
本发明可以至少可以达到以下的有益效果：
本发明将散热器分割为第一散热片和第二散热片，并分别置于投影机的两个安装面上，以此消除装配过程中散热片的两个安装面之间的相互影响，即，本发明通过设置相对独立的散热片，增强了散热器与投影机安装面之间的压紧力，从而有效防止了因散热器的散热性能下降而导致的投影机出现的投影问题。
尽管为示例目的，已经公开了本发明的优选实施例，本领域的技术人 员将意识到各种改进、增加和取代也是可能的，因此，本发明实施例的范围应当不限于上述实施例。
工业实用性
本发明实施例中，通过将散热器分割为第一散热片和第二散热片，并分别置于投影机的两个安装面上，实现散热器与投影机的完全接触，从而有效防止了因散热器的散热性能下降而导致的投影机出现的投影问题。
