Description

散热装置及应用该散热装置的投影设备 技术领域
本申请涉及光学投影设备技术领域，具体涉及一种散热装置及应用该散热装置的投影设备。
 背景技术
色轮在激光光源在照明、投影、光学照排、光存储等领域中应用广泛。在这些应用中，需要将光源通过色轮转化成不同颜色的光，而光源照射到色轮轮盘时，因部分光能转化成热能，会导致温度急剧上升。而常用的色轮散热技术在解决光能越来越高的领域不够理想，比如光斑的功率较大时，其内部器件温度会超过规定温度，导致色轮无法长时间正常工作。
 技术问题
现有技术中主要通过吹风对色轮散热，其散热效果一般。具体的，如图1所示，色轮装置包括壳体101、马达102，固定架103、色轮104及盖板105。色轮104的热量主要通过内部空气对流传热及色轮104、固定架103、马达102间的热传导两种方式传递外部壳体101及盖板105，其中壳体101占主要部分，再通过系统风量与壳体101间的强制对流作用将热量带走。由于空间限制壳体101及盖板105散热面积有限，通过与系统风量对流作用带走的热量有限，在高亮度、色轮发热量较大时，无法将色轮104热量及时带走而集聚的热量只能传导到马达102壳上，致使马达102的壳温度升高，会降低马达102的正常工作寿命。色轮的散热问题则得不到有效解决，其效率和寿命也会降低。
 技术解决方案
本申请提供一种适用于复杂结构且散热效果好的散热装置及应用该散热装置的投影设备。
一方面，一种实施例中提供一种散热装置，包括：
热管，其镶嵌在被散热器件上，被散热器件为热量产生器件或与热量产生器件直接接触的器件；
以及换热装置，其安装在被散热器件上，热管至少一部分至与换热装置接触；换热装置上设有制冷液进口和制冷液出口，内部还设有流道，制冷液进口和制冷液出口通过流道联通。
另一方面，另一种实施例中提供了一种应用该散热装置的投影设备，包括激发光产生装置、受激光产生装置和壳体，激发光产生装置用于发射激发光，受激光产生装置用于在激发光产生装置的照射下产生受激发光，受激光产生装置安装在壳体内，还包括散热装置，散热装置包括：
热管，其镶嵌在壳体上；
以及换热装置，其安装在壳体上，热管至少一部分至与换热装置接触；换热装置上设有制冷液进口和制冷液出口，内部还设有流道，制冷液进口和制冷液出口通过流道联通。
 有益效果
依据上述实施例的投影设备及适用于复杂结构的散热装置，散热装置由于在被散热器件上镶嵌有热管，还安装有具有流道的换热装置，使得被散热器件的热量能够被热管收集，热管与换热装置接触，可将热量传递给热装置，热装置再通过循环导入的制冷液或制冷气体将热量带走，从而能快速降低被散热器件的温度，并且热管可弯曲设置，满足不同复杂结构装置的安装，能延伸到不同的位置，便于全面收集热量，从而提高效率，延长使用寿命。

 本发明的最佳实施方式
下面通过具体实施方式结合附图对本实用新型作进一步详细说明。
在本实用新型实施例中，提供了一种投影设备及一种散热装置，散热装置可用于具有复杂结构的被散热器件的散热，被散热器件可为热量产生器件或与热量产生器件直接接触的器件。在本实施例中，散热装置安装在投影设备的上，散热装置还可安装到手机、电脑等上，实现对其散热。
投影设备包括激发光产生装置、受激光产生装置、壳体和散热装置，激发光产生装置为光源用于发射激发光，受激光产生装置为色轮，色轮在在激发光产生装置的照射下产生特定颜色的受激发光。色轮安装在壳体内。壳体为不规则结构，且表面具有大量的安装孔。散热装置安装在壳体上。
具体的，如图2所示，散热装置包括热管201和换热装置202。
热管201包括三条，热管201是利用介质在热端蒸发后在冷端冷凝的相变过程（即利用液体的蒸发潜热和凝结潜热），使热量快速传导。热管201由管壳、吸液芯和端盖组成。热管201内部是被抽成负压状态，充入适当的液体，这种液体沸点低，容易挥发。管壁有吸液芯，其由毛细多孔材料构成。热管201一端为蒸发端，另外一端为冷凝端，当热管一端受热时，毛细管中的液体迅速汽化，蒸气在热扩散的动力下流向另外一端，并在冷端冷凝释放出热量，液体再沿多孔材料靠毛细作用流回蒸发端，如此循环不止，直到热管两端温度相等（此时蒸汽热扩散停止）。
三条 热管201的内部结构和原理与现有技术的热管一致，不同点在于三条热管201的外形结构是根据壳体203表面设置的。三条热管201分别镶嵌在壳体203的表面，且分别从壳体203的一端弯曲延伸至另一端，以致三条热管201能够尽可能的延伸到壳体203表面的各角落，便于热管201更好更快的收集壳体203的热量。在其他实施例中，也包括一条或其他数量的弯曲的热管201，及热管201可延伸至壳体203的内部，提高热管201收集热量的能力。
本实施例优选的，向换热装置202循环导入制冷液实现制冷，在其他实施例中，也可通过导入制冷的气体，实现带走换热装置202内的热量。
换热装置202包括第一壳体2021、换热器2022和第二壳体2023。第一壳体2021为板状结构，第一壳体2021通过螺钉安装在壳体203的表面一端，覆盖在三条热管201的端部上，并且与三条热管201接触。第二壳体2023安装在第一壳体2021上，与第一壳体2021围合成容置换热器2022的腔体，第二壳体2023上设有制冷液进口2023-1和制冷液出口2023-2。换热器2022与现有技术中热换器的结构和原理一致，具有弯曲的流道，换热器2022安装在第一壳体2021上，容置于第一壳体2021和第二壳体2023围合成的腔体内，并且换热器2022的流道与第二壳体2023的制冷液进口2023-1和制冷液出口2023-2联通，制冷液可从制冷液进口2023-1导入，经过流道，再从制冷液出口2023-2排出。
在其他实施例中，换热装置202为一体式结构，在换热装置202上设有制冷液进口和制冷液出口，在内部设有弯曲的流道，且部分流道靠近换热装置202的安装面，便于热量传递。
本实施例提供的一种适用于复杂结构的散热装置的散热原理为：通过三条热管201收集壳体203上的热量，并传导至第一壳体2021上，换热器2022通过第一壳体2021吸收热量，并通过流动的制冷液带着热量，制冷液通过外部水泵驱动循环导入。由于热管201具有保持整体温度均匀的特性，当接触第一壳体2021的一端的温度被吸走后，温度降低，热管201其他部位的温度就会被传递到温度低的一端，从而使得热管201不断从色轮壳体上吸收热量并传递到第一壳体2021上。其中色轮将热量传导至色轮壳体的原理与现有技术一样，通过内部空气对流及部件连接传导。
本实施例的适用于复杂结构的散热装置，由于在壳体203上镶嵌有三条热管201，还安装有具有流道的换热装置202，使得壳体203上的热量能够被热管201收集，热管201与换热装置202接触，可将热量传递给冷换热装置202，冷换热装置202再通过流动的制冷液将热量带走，从而能快速降低色轮壳体201的温度，并且热管201可弯曲设置，满足不同复杂结构装置的安装，能延伸到不同的位置，便于全面收集热量。
以上应用了具体个例对本实用新型进行阐述，只是用于帮助理解本实用新型，并不用以限制本实用新型。对于本实用新型所属技术领域的技术人员，依据本实用新型的思想，还可以做出若干简单推演、变形或替换。
