Description

换热器及色轮换热系统及投影设备 技术领域
本实用新型涉及光学散热技术领域，具体涉及一种换热器及包含该换热器的色轮换热系统及投影设备。
 背景技术
色轮等很多光学器件在工作时，不仅对散热条件要求非常高，同时对密封防尘能力的要求也是十分的苛刻。针对小功率色轮的散热和防尘设计，传统的热管翅片散热器即可满足要求，其可以设计成穿过色轮腔体进入内部，把热量传导出来，同时也能满足色轮的防尘要求 。
技术问题
但当面对大功率的色轮时，其散热能力却远远不能满足，此时就需要使用空-液换热方案的换热器。空-液换热方案的换热器主要利用循环液体极高的比热快速带走色轮产生的热量，达成色轮散热要求。换热器、循环风道以及色轮腔体共同组成一套装置，来实现大功率色轮的散热及防尘要求。为做到很好的防尘效果，需要换热器的两个安装面具有很高的平面度，通常需要设计一个框架来实现平面度的要求。如图1所示，为现有技术的换热器，包括第一水箱101、框架102、第二水箱103以及换热芯体104，其中换热芯体104需要装进框架102里，在接触部位使用焊粉或焊料把二者焊接在一起，然后再把第一水箱101和第二水箱103分别与框架102的两端通过摩擦焊的工艺焊接在一起。此结构中，换热芯体与框架需要焊接的十分精准，才能保证框架的上下两个安装面的平面度而不至于漏气漏灰尘，且因为二者接触面太多，这就需要换热芯体和框架的加工精度都要非常高。另外，换热芯体和框架焊接一起后尚无法检测焊接质量，也就不能判断密封性能，只有把两端的水箱同时焊接上去后才能通过压力测试的手段来判定所有的焊接质量，一旦压力测试不合格，整个换热装置就只能报废，这就会造成换热装置单价的上升。
因此，实有必要提供一种新的换热器以及换热系统以解决上述问题。

如图2和图3所示，本实用新型换热器100包括第一水箱201、第二水箱203、侧板202和换热芯体204。
换热芯体204连接第一水箱201和第二水箱203，其中第一水箱201上设有与其一体成型的进水嘴20101和出水嘴20102，在安装时，将第一水箱201的进水嘴20101接通水源，出水嘴20102则接通排水处；当往第一水箱201的进水嘴20101通水时，水进入第一水箱20101，经过换热芯204再进入到第二水箱203，然后水再从第二水箱203经换热芯204进入到第一水箱201从第一水箱201的出水嘴20102排出，由于产品内部的热量传递到换热芯40上，流通的水将换热芯40上的热量带走，从而实现对产品的散热。
其中换热芯体204包括至少一个流道2041以及围绕流道2041设置的换热翅片2042。优选的，流道2041为多个，在换热芯体204内形成多个流体平面。相邻两个流道2041之间均夹设有换热翅片2042，即换热翅片2042围绕流道2041设置从而实现流道2041内液体与换热翅片2042的热量交换。
换热芯体204包括分别与第一水箱201和第二水箱203相连的两第一表面20401、连接两第一表面20401的两第二表面20402和两第三表面20403，其中第二表面20402沿平行于流道2041即平行于流体平面的第一方向设置，第三表面20403沿垂直于流道2041的第二方向设置。具体在本实施方式中，第一表面20401、第二表面20402和第三表面20403都是平面，即整个换热芯体204形成一个立方体，在可选择的其他实施方式中，也可以为非平面结构。
进一步的，换热芯体204还包括用于防止水浸入到换热翅片2042内的堵头2043，每组换热翅片均设置有一对堵头2043，分别位于换热翅片2042靠近两第一平面20401即靠近第一水箱201和第二水箱203的两侧。同一侧相邻两个堵头2043夹设在流道2041的自由端，堵头2043靠近第一水箱201和第二水箱203的外表面与流道2041的自由端共同形成第一表面20401。
侧板202贴设在换热芯体的第二表面20402上，且侧板202在第二方向上的自由端超出换热芯体的两第三表面20403，侧板202在沿第一方向上的自由端与第一表面20401平齐。进一步的，侧板202在第二方向上设置有用于与外部连接的连接装置2021，使得侧板在第二方向上的平面作为换热器的安装面。在本实施方式中，连接装置2021为连接孔，优选的，连接孔为螺纹孔，安装方式为螺钉固定。在可选择的其他实施方式中，还可为由焊锡组成的焊接面、由粘胶组成的粘结面等，固定方式采用焊接或是粘胶，也是可以实施的，只要可以保证换热器的安装，形成安装面，即是可以实施的。
这样的结构，首先，侧板202在沿第一方向上的自由端与第一表面20401平齐，可以便于侧板202和换热芯体204与水箱的固定，以便保证水箱与流道的密封性能。侧板202在第二方向上的两自由端分别对应超出换热芯体的两第三表面20403，两自由端上均设置有连接装置2021，具体在本实施方式中为连接孔。这样，不仅可以便于换热器的安装，同时，在自由端上设置连接孔，也便于在其上采用各种加工方式对连接孔进行加工，例如钻出螺纹孔等。需要说明的是，本实施方式采用的侧板需要保证厚度足够，优选为在5-7mm之间，这样，可以保证产品的性能。
第一水箱201和第二水箱203上均设置有向换热芯体204方向凸出的焊接部2011，焊接部2011与侧板202和换热芯体204焊接固定。参照图4和图5，焊接部2011抵接在侧板202和换热芯体204的交界处，具体为抵接在侧板202和堵头2043的交界处，并在此处进行焊接固定。优选的，在侧板202和焊接部2011之间进行焊接。
在本实施方式中，第一水箱201上还设置有向换热芯体204方向凸出的定位部2012，对应的，换热芯体204的堵头2043上设置有与定位部2012对应设置的卡槽20431，定位部2012与卡槽20431配合设置，实现第一水箱201与换热芯体204之间的定位，以保证水箱与流道的密封性能。
本实施方式的换热器在安装时，首先，在换热芯体与第一水箱201、第二水箱203的接触部位使用焊粉，把这几个部件焊接在一起；如图4和图5所示，使得定位部2012与卡槽20431相匹配以保证流道与水箱完整密封对接。焊接后需要测试耐压性能，以保证加工好的半成品不漏水，如果出现漏水，则需要补焊，直至耐压测试通过；然后使用摩擦焊工艺，将两个侧板与两个水箱焊接在一起，这样两个水箱与换热芯体的两个侧板就合围成一个框架，可以保证换热器整体的强度；在形成的框架的上下两个面上使用铣刀加工，以保证足够的平面度；最后在上述两个面上设计几个螺纹孔，以便固定换热器。
如图6所示，本实用新型还提供一种应用上述换热器的色轮换热系统和投影设备，色轮换热系统包括具有色轮腔体200的壳体、收容在色轮腔体200内的色轮300、风扇400和换热器100，换热器100安装在色轮腔体200中以形成循环风道以冷却色轮300。其中壳体与侧板202通过连接孔2021连接在一起，具体的，为通过连接孔2021进行螺钉固定。
本实用新型的有益效果是：区别于现有技术的情况，本实用新型提供一种换热器，换热器的侧板在第二方向的自由端超出换热芯体的第三表面，并且侧板上设置有连接装置，使得侧板可以直接充当换热器的安装板，两侧板分别与第一水箱和第二水箱连接在一起，可以充当支撑换热器的框架，提高换热器整体的安装强度，且换热芯体与水箱连接，减少换热器的焊接零件和焊接步骤，提高焊接良率，减轻换热器重量，降低成本，具有良好的用户体验。
