所述第一液冷板101至第N液冷板10n与所述热交换器300之间相连通，且所述泵200连接于所述第一液冷板101至第N液冷板10n与所述热交换器300之间。
具体的，第一液冷板至第N液冷板的不同液冷板之间，以及，液冷板与热交换器之间均通过传输管道相连通，且泵连接于传输管道上，保证液冷板和热交换器之间实现水冷液的流通。需要说明的是，本申请实施例对于提供的散热装置中液冷板、泵和热交换器内流动的冷媒可以为水，还可以为液氮等，对此本申请实施例不作具体限制；此外，本申请实施例对于提供的液冷板、热交换器的热交换板和传输管道的材质不作具体限制，需要根据实际需要进行具体设计。
参考图1所示，对于本申请实施例提供的所述热交换器可以为风冷热交换器，热交换器可以包括：
热交换板301，所述热交换板301与所述第一液冷板101至第N液冷板之间10n相连通；
以及，固定于所述热交换板301上的至少一个散热风扇302。
其中，水冷液通过泵的牵引回流至热交换板中，而后通过散热风扇转动产生的风量与热交换板发生强制对流作用将热量带走，以对水冷液进行冷却，而后再次通过泵的牵引流入液冷板中对热源进行散热。
由上述内容可知，将液冷板与热源相接触设置，进而在散热装置工作过程中，泵牵引水冷液开始流动，使得水冷液自热交换器流入液冷板中，通过液冷板吸收与其接触的热源所产生的热量后，水冷液回流至热交换器中散热，达到对热源散热的目的，并且每个液冷板中的水冷液统一通过热交换器进行散热，保证了散热装置的占用体积小。此外，每个液冷板中的水冷液统一通过热交换器进行散热，只需要对一个热交换器中设置风扇即可，避免了大量使用风扇而出现噪音过大的情况，同时还降低了功率消耗。
本申请实施例提供的散热装置中，所有液冷板之间可以相互并联、且连通于热交换器，即，参考图1所示，所述泵200的进水口与所述热交换器300的出水口相连通；
所述泵200的出水口与所述第一液冷板101至第N液冷板10n的进水口相连通；
以及，所述第一液冷板101至第N液冷板10n的出水口均与所述热交换器300的进水口相连通。
需要说明的是，相较于图1中泵所示的牵引方向，当散热装置中所有液冷板之间相互并联时（即图1所示的连接结构），其泵的牵引方向还可以与图1中泵所示的牵引方向相反。
其中，泵牵引水冷液自热交换器传输至每个液冷板中，通过液冷板吸收各自相对应的热源散发的热量后，根据泵的牵引方向传输至热交换器中，热交换器对水冷液进行散热冷却，而后再次被牵引至液冷板中吸收热量，如此重复达到对热源散热的目的。
另外，本申请实施例提供的散热装置中，所有液冷板之间还可以相互串联、且连通于热交换器，即，参考图2所示，为本申请实施例提供的另一种散热装置的结构示意图，其中，所述泵200的进水口与所述热交换器300的出水口相连通；
所述泵200的出水口与所述第一液冷板101的进水口相连通；
以及，所述第一液冷板101至第N液冷板10n中第i液冷板的出水口与第i+1液冷板的进水口相连通，且所述第N液冷板10n的出水口与所述热交换器300的进水口相连通，i为不大于N的正整数。
或者，相较于图2中泵的牵引方向，本申请实施例提供的泵的牵引方向还可以与图2提供的泵牵引方向相反，即，参考图3所示，为本申请实施例提供的又一种散热装置的结构示意图，所述泵200的出水口与所述热交换器300的进水口相连通；
所述泵200的进水口与所述第一液冷板101的出水口相连通；
以及，所述第一液冷板101至第N液冷板10n中第i液冷板的进水口与第i+1液冷板的出水口相连通，且所述第N液冷板10n的进水口与所述热交换器300的出水口相连通，i为不大于N的正整数。
其中，本申请实施例图2和图3提供的散热装置，热交换器中的水冷液通过泵的牵引逐一流过每个液冷板，吸收每个液冷板对应的热源散发的热量后，最终流入热交换器中进行散热冷却，而后再次被牵引至每个液冷板中逐一吸收热量，如此重复达到对热源散热的目的。
相应的，本申请实施例还提供了一种投影机，参考图4所示，为本申请实施例提供的一种投影机的结构示意图，需要说明的是，本申请实施例以热源组包括三个热源为例进行说明，即N为3。
其中，投影机包括热源组，所述热源组包括有第一热源至第N热源（即参考图4中第一热源101’、第二热源102’和第三热源103’），N 为不小于2的整数，所述投影机还包括散热装置，所述散热装置包括：
第一液冷板101至第N液冷板103、泵200和热交换器300，
其中，所述第一液冷板至第N液冷板分别与所述第一热源至第N热源’相接触设置（即参考图4中第一液冷板101与第一热源101’接触设置，第二液冷板102与第二热源102’接触设置，第三液冷板103和第三热源103’接触设置），所述第一液冷板101至第N液冷板103与所述热交换器300之间相连通，且所述泵200连接于所述第一液冷板101至第N液冷板103与所述热交换器300之间。
参考图4所示，本申请实施例提供的投影机中，所述热交换器可以为风冷热交换器，其中，热交换器300包括：
热交换板301，所述热交换板301与所述第一液冷板101至第N液冷板103之间相连通；
以及，固定于所述热交换板301上的至少一个散热风扇302。
由上述内容可知，将液冷板与热源相接触设置，进而在散热装置工作过程中，泵牵引水冷液开始流动，使得水冷液自热交换器流入液冷板中，通过液冷板吸收与其接触的热源所产生的热量后，水冷液回流至热交换器中散热，达到对热源散热的目的，并且每个液冷板中的水冷液统一通过热交换器进行散热，保证了散热装置的占用体积小。此外，每个液冷板中的水冷液统一通过热交换器进行散热，只需要对一个热交换器中设置风扇即可，避免了大量使用风扇而出现噪音过大的情况，同时还降低了功率消耗。
本申请实施例提供的投影机中，其散热装置的所有液冷板之间可以相互并联、且连通于热交换器，即，所述泵的进水口与所述热交换器的出水口相连通；
所述泵的出水口与所述第一液冷板至第N液冷板的进水口相连通；
以及，所述第一液冷板至第N液冷板的出水口均与所述热交换器的进水口相连通。
需要说明的是，散热装置中所有液冷板之间相互并联时，其泵的牵引方向还可以与上述所述泵的牵引方向相反。
其中，泵牵引水冷液自热交换器传输至每个液冷板中，通过液冷板吸收各自相对应的热源散发的热量后，根据泵的牵引方向传输至热交换器中，热交换器对水冷液进行散热冷却，而后再次被牵引至液冷板中吸收热量，如此重复达到对热源散热的目的。
另外，本申请实施例提供的投影机中，其散热装置的所有液冷板之间还可以相互串联、且连通于热交换器，即，所述泵的进水口与所述热交换器的出水口相连通；
所述泵的出水口与所述第一液冷板的进水口相连通；
以及，所述第一液冷板至第N液冷板中第i液冷板的出水口与第i+1液冷板的进水口相连通，且所述第N液冷板的出水口与所述热交换器的进水口相连通，i为不大于N的正整数。
或者，所述泵的出水口与所述热交换器的进水口相连通；
所述泵的进水口与所述第一液冷板的出水口相连通；
以及，所述第一液冷板至第N液冷板中第i液冷板的进水口与第i+1液冷板的出水口相连通，且所述第N液冷板的进水口与所述热交换器的出水口相连通，i为不大于N的正整数。
进一步的，在所有液冷板之间相互串联时，靠近所述热交换器进水口的液冷板所对应的热源，其产生的热量大于其余热源分别产生的热量。即，水冷液最后流过产生热量较大的热源，避免出现先流过该热源时水冷液吸收足够热量而不能再次对其他热源产生的热量进行吸收的情况，保证散热装置对每个热源均能够进行散热冷却。具体的，当热源组包括有光源模组、色轮和处理芯片时，可以将发热量较大的光源模组与靠近热交换器进水口的液冷板接触设置，而将发热量较小的处理芯片与靠近热交换器出水口的液冷板接触设置，且将色轮设置于上述两个液冷板之间。其中，本申请实施例提供的处理芯片可以为DMD（Digital Micromirror Device，数码微镜器件）芯片。
相应的，本申请实施例还提供了一种投影***，所述投影***包括上述任意一实施例提供的投影机。
本申请实施例提供了一种散热装置、投影机及投影***，包括热源组，所述热源组包括有第一热源至第N热源，N 为不小于2的整数，所述投影机还包括散热装置，所述散热装置包括：第一液冷板至第N液冷板、泵和热交换器，其中，所述第一液冷板至第N液冷板分别与所述第一热源至第N热源相接触设置，所述第一液冷板至第N液冷板与所述热交换器之间相连通，且所述泵连接于所述第一液冷板至第N液冷板与所述热交换器之间。
由上述内容可知，散热装置工作过程中，水冷液自热交换器流入液冷板中，通过液冷板吸收与其接触的热源所产生的热量后，水冷液回流至热交换器中散热，达到对热源散热的目的。本申请实施例提供的技术方案，通过散热装置对投影机内的热源进行散热冷却，避免出现热源产生的大量热量不能散热而积聚的情况，并且每个液冷板中的水冷液统一通过热交换器进行散热，保证了散热装置的占用体积小。
