 本发明的最佳实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图1～5及实施例，对本实用新型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实用新型，并不用于限定本实用新型。
需要说明的是，本实施例中的上、下等方位用语，仅是互为相对概念或是以产品的正常使用状态为参考的，而不应该认为是具有限制性的。
如图1至图5所示，本实用新型实施例提供的换热器，包括第一水箱10、第二水箱20、外壳30和换热芯40，外壳30优选是一体成型，也可以是分体成型，外壳30形成可供气流经过的一容置腔31，换热芯40设于容置腔31内，换热芯40内设置有供液体流通的水道411（以下将作进一步说明），第一水箱10和第二水箱20分别固定于述容置腔31的两侧且与换热芯40的水道411连通；第一水箱10和第二水箱20上分别设有进水嘴11和出水嘴21，例如，在一个实施方式中，进水嘴11和出水嘴21分别设置在第一水箱10和第二水箱20的第一面P1上。液体从进水嘴11流入后，流经换热芯40内的水道411，从出水嘴21流出。由于换热器100的分别设置在第一水箱10和第二水箱20上的进水嘴11和出水嘴21相对地位于外壳30的两端，因此，相较于进水嘴和出水嘴共同设置第一水箱或第二水箱上所造成的部件安装空间狭小的缺陷，换热器100可以为与进水嘴11和出水嘴21相连通的管道及布置在换热器100附近的其它部件提供较大的安装空间，从而提升换热器100的安装效率，提高了换热器100在其所安装的需要换热的装置中的安装位置灵活度，从而使换热器100可以适用于更多的使用场合。另外，液体从进水嘴11流入后流经换热芯40内的水道411就直接出水嘴21流出，因此，流入换热器100的液体一次性地与气流进行换热，可以获得液体与气流之间一直较大的温差，可以明显提高换热器100的换热性能。
参照图1及图3，第一水箱10和第二水箱20分别具有一个第二面P2，各第二面P2分别与相邻的容置腔31的一开口（未图示）相对，至少一个第二面P2具有沿远离该相邻的容置腔31的开口并朝着接近进水嘴11或出水嘴21的中心轴线方向延伸的倾斜面P21，倾斜面P21可以增加第一水箱10或第二水箱20的散热面积，尤其是增加第二水箱20的散热面积。当第一水箱10和第二水箱20分别具有该第二面P21时，第一水箱10的倾斜面P21可以起到引导第一水箱10中的水流以较均匀水量地流向各隔板的水道411中，使得各水道411所吸收热量均匀和稳定，并且第二水箱20的倾斜面P21起到了引导第二水箱20中的水以较少阻力地流向出水嘴21，加速水流流出出水嘴21的作用，提升了换热器100的换热效率。需要说明的是，上述的朝着接近进水嘴11或出水嘴21的中心轴线方向延伸，并不是指精确地对着中心轴线，仅为了说明倾斜面P21是朝着接近中心轴向的方向倾斜。
进一步地，进水嘴11和出水嘴21中的一个包括直连通管，另一个包括弯连通管。在本实施例中，进水嘴11包括直连通管，出水嘴21包括弯连通管，通过将进水嘴11和出水嘴21设置成具有不同形状的连通管，可以为换热器100根据与进水嘴11和出水嘴21相连通的管道的走向、长度等以及换热器100所安装于的需要换热的装置中布置的其他部件等实际情况更灵活地确定换热器100的两个水嘴中的一个作为进水嘴，另一个作为出水嘴，增加了换热器的适用性。
参照图1及图3，换热芯40包括间隔设置的若干块隔板41和设置于隔板41两侧的散热翅片42，水道411开设于隔板41的长度方向，第一水箱10的内侧设有与进水嘴11连通的进水槽（未图示），第二水箱20的内侧设有与出水嘴21连通的出水槽（未图示），具体的，需要换热的装置散发出的热量会通过比如气流的方式被风扇传递在散热翅片42上，而经与第一水箱10连通的进水嘴11进入到第一水箱10的水在水压的驱使下流经与其连通的隔板41的水道411进入到第二水箱20，水再从与第二水箱20连通的出水嘴21排出，那么在水流的流动过程中，会带走从散热翅片42传递到隔板41上的热量，从而实现换热。在若进水嘴和出水嘴同时设置在两个水箱中的其中一个的情况下，水流需要经过流入其中一个水箱后再流入另一个水箱最后又流回该其中一个水箱中才被排出的过程，在水流由另一个水箱最后流回该其中一个水箱的过程中（可以理解为回流），由于水流已经经过了一次换热，水流的水温较高，再一次与气流换热时将导致水流的换热性能显著下降，相当于同一液体与气流进行了两次换热。而本实用新型的换热器的进水嘴11和出水嘴21分别设置于位于外壳30相对两端的第一水箱10和第二水箱20上，水流从第一水箱10直接流入第二水箱20（可以理解为直流），不经过上述的回流过程，因此，直流的水流的水温相比于回流的水流的水温要低，因此，可以明显提高水流的换热性能，进而也提升了换热器100的换热效果。
作为进一步的改进，对于第一水箱10和第二水箱20的第一面P1上分别与进水嘴11和出水嘴21相连通的连通口（未图示），可以将该各连通口设置成位于各第一面P1的大致中心处，如此的话，可以减小第一水箱10和第二水箱20之间的水流的流水阻力，降低水流紊流，进而也提升了换热器100的散热性能。
结合图1-4参照图5，作为上述各种实施方式的换热器的一种具体应用，一种投影装置的色轮散热模组1000具有上述的换热器100、色轮腔体200、色轮300和风扇400，色轮300和风扇400布置在色轮腔体200中。换热器100的容置腔31与色轮腔体200密封连接以形成一密闭空间，比如，作为一种上述密封连接的具体结构，色轮腔体200包括两个相对的间隔设置、具有相同管径的管道，换热器100的容置腔31布置在该间隔设置的管道之间，容置腔31的两侧分别与两个管道的管口密封连接，由此，容置腔31与色轮腔体200可一起形成回字形或圆环形气流通道。因此，对于对防尘散热有着很高要求的色轮300来说，色轮散热模组1000不仅通过换热器100过与色轮腔体200密封连接保证了对色轮300的良好的防尘性能，而且，根据上述各种实施方式换热器100所具有的各种优点，本色轮散热模组1000也相应的具有上述各种优点，在此不再赘述，从而色轮散热模组1000中的色轮300的温度可以被很大程度地降低，色轮寿命得以延长。另外，对于小型化和紧凑型要求较高的投影装置，色轮散热模组的进水嘴、出水嘴分别设置在不同水箱上的换热器相较于进出嘴、出水嘴设置在同一水箱的现有换热器，为投影装置中的其他部件的灵活布置提供了便利，从而能够有效地利用投影装置中的整体空间。
作为进一步的改进，色轮腔体200包含第一通口端和第二通口端，色轮腔体200内形成有从第一通口端（未图示）至第二通口端（未图示）的通道。色轮300和风扇400设置于通道内，容置腔31包括第一开口框和第二开口框，第一通口端与第一开口框密封连接，第二通口端与第二开口框密封连接，使得色轮腔体200和容置腔31构成密闭腔体，且色轮腔体200内的通道与容置腔31的内部空间共同构成供密闭腔体内的气体循环流动的气流通道。因此，通过上述密封连接所形成的气流通道，不仅很好地保证了色轮300的防尘，而且换热器100的换热芯40通过水道411中的液体对经过换热芯40的气流换热，相对于普通的风扇与散热鳍片配合散热的散热效果更好。
作为一种具体实施方式，第一开口框和第二开口框位于容置腔31的相对的两侧。这样的话，有利于容置腔31与色轮腔体200的配合安装。
上述换热芯40优选地大致沿同一方向排布多条水道411，在上述气流通道内循环流动的气流流经换热芯40的方向与水道411的排布方向垂直。通过如此设置，使得气流与水道411中的液体进行热交换的面积最大，有利于换热器100获得良好的换热效果。
作为优选的实施方式，换热器100的外壳30由上安装板32、下安装板33和两个侧板34一体围合形成，上安装板32和下安装板33分别包括上述第一开口框和第二开口框，第一开口框和第二开口框设有通风口(未图示) 和用于安装连接的若干第一螺孔35，两通风口即作为整个换热芯40的进风侧和出风侧，也就是说，色轮腔体200与两通风口相互连通并与围绕该各通风口的容置腔31的第一开口框和第二开口框形成气密封。如此的话，通风口的设置有利于位于密闭空间中色轮1所产生的热量被传递到外壳30内设置的换热芯40 上，而第一螺孔35的设置则方便通过紧固件将上安装板31和下安装板32与色轮腔体200具有的对应的若干第二螺孔（未图示）安装连接，紧固件一般可采用螺钉、螺栓等。可知的是，色轮腔体200是由容纳色轮、风扇的容纳室、管道等部件密封连接所形成的密闭的、可供气流循环流动的通道，在色轮腔体200中布置色轮300和风扇400，风扇400驱动经由换热器100所换热的气流对色轮300进行散热。作为一种第一螺孔35和第二螺孔的连接结构，可以在上述两个间隔设置的管道的管口处设置具有上述第二螺孔的凸缘状的上述第一通口端至第二通口端，若干螺栓经过成对的第一螺孔和第二螺孔而将换热器的容置腔31与色轮腔体200密封连接起来。
为了使色轮散热模组1000具有更好的密封性能，在上安装板32和下安装板33与色轮腔体200之间分别布置密封件，具体来说，在上安装板32和下安装板33与上述两个间隔设置的管道的管口之间分别布置环形密封件，密封件的个数及形状可以根据实际情况而具体选择。
更优的，依照色轮腔体200中的气流循环方向，换热器100的容置腔31、风扇400和色轮300依次设置，并且面对风扇400的散热翅片42的间隙小于背离风扇400的散热翅片42的间隙。也就是说，经换热器100冷却的气流（可以理解为冷风）在风扇400作用下首先经过风扇400，再经过色轮300，因此，冷风可以首先对风扇400进行散热，降低风扇400的温度，由于风扇400的发热量远低于色轮300的放热量，经过风扇400的冷风相对于色轮300仍有很大的温差，从而冷风仍能带走色轮300所发出的大部分热量，经过了色轮300之后的气流（可以理解为热风）在风扇400作用下进入换热器100，如此循环。并且，散热翅片42的间隙被设置成由远离至接近风扇400而逐渐较小，可以得知，越靠近风扇400，风扇400的抽吸力越逐渐增大，所以，散热翅片42的散热面积也越被增加，从而提高了散热效率，而由于风扇400的抽吸力也逐渐增大，因此，增加散热面积所带来的风阻并不明显。
本实用新型还提供了一种投影装置，投影装置采用上述任一实施例的色轮散热模组，参照以上所描述的色轮散热模组的优点，因此，提高了投影装置中色轮的散热效率，提升了投影装置的工作性能。
在以上对本实用新型的描述中，需要理解的是，所描述的“水”，应做广义的理解，即理解为包括水、冷却液或制冷剂等的液体，
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。
以上内容是结合具体的实施方式对本实用新型所作的进一步详细说明，不能认定本实用新型的具体实施只局限于这些说明。对于本实用新型所属技术领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干简单推演或替换。
