Description

放映机 【技术领域】
本发明涉及放映机技术领域，尤其涉及一种符合DCI认证的放映机。
【背景技术】
随着人们生活水平的不断提高，电影院中的放映机的放映品质和保密的要求也越来越高。符合数字版权唯一标识符(英文为Digital Copyright Identifier，简称DCI)认证要求的放映机越来越重要。其中，放映机的散热结构为其重要的部件。
相关技术的放映机的散热结构包括外壳和连接于外壳的散热器。
然而，目前的放映机在满足DCI认证要求的防篡改规定，将其连接于所述散热器的所述外壳设置为迷宫结构。该迷宫结构可以阻隔视线，观察者不借助特殊工具的话，看不到放映机内部器件。该方案的外壳的结构设计较复杂，而且体积较大，并且系统风道阻力较大，风扇的散热作用不能有效释放出来，往往为了获得足够的风量和风压而选型尺寸较大或尺寸较厚的风扇，这就导致放映机的整机尺寸和噪音都比较大。
【发明内容】
本发明的目的是克服上述技术问题，提供一种满足DCI认证要求、通风状况佳、系统散热性能好且噪音低的放映机。
为了实现上述目的，本发明提供一种放映机，包括具有收容空间的壳体和固定于所述收容空间内的散热器，所述散热器包括相互叠设且平行间隔设置的多块散热翅片，多块所述散热翅片抵接于所述壳体的一端共同形成出风面，多块所述散热翅片远离所述出风面的一端共 同形成进风面，其特征在于，所述壳体包括贯穿其上设置的多个百叶窗结构，所述出风面抵接所述壳体且完全覆盖所述百叶窗结构，所述收容空间依次通过所述散热器和所述百叶窗结构与外界连通。
更优的，所述百叶窗结构包括分别贯穿所述壳体的多个通风孔以及由所述壳体的外表面向远离所述散热器的方向倾斜延伸的多块叶片，每一所述叶片与一个所述通风孔相对设置，且所述叶片向与其对应的所述通风孔的正投影完全覆盖该通风孔。
更优的，所述通风孔呈矩形，所述散热翅片平行于所述通风孔的长轴设置，所述叶片由所述通风孔的长轴边弯折延伸形成。
更优的，多个所述通风孔呈阵列排布。
更优的，所述散热翅片的宽度与所述叶片远离所述通风孔的一端距所述通风孔的高度呈正相关。
更优的，所述散热翅片的宽度为40mm，所述叶片远离所述通风孔的一端距所述通风孔的高度为4mm。
更优的，与所述叶片连接的所述壳体所在的平面与该叶片之间夹角的角度为40°。
更优的，多块所述叶片相对于所述壳体的倾斜方向相同。
更优的，所述百叶窗结构还包括由所述通风孔的两个短轴边分别垂直延伸的两块连接片，两块所述连接片分别和与该通风孔对应的所述叶片的相对两侧连接。
更优的，所述放映机还包括安装于所述收容空间内的风扇，所述风扇转动时将所述收容空间内的空气依次通过所述散热器和所述通风孔排出至所述壳体外。
与现有技术相比，本发明提供的放映机通过壳体设有贯穿其上设置的多个百叶窗结构，并使散热器的多块散热翅片形成的出风面抵接所述壳体且完全覆盖百叶窗结构，从而使所述壳体内的收容空间依次通过散热器和百叶窗结构与外界连通，该结构不需要将所述壳体设置为迷宫结构，而且系统风道阻力较小，从而使所述放映机的通风状况 佳、系统散热性能好且噪音低。另外，所述壳体设置的多个百叶窗结构具有遮挡光线直线射入的作用，该结构可以确保放映机的内部板卡、线材等不可见，且保证观察者无法从外部伸入简易的工具，即不能获取放映机内部的信息，也就是说，该结构满足DCI认证中的防篡改规定，从而使本发明的放映机满足DCI认证的要求。
【附图说明】
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图，其中：
图1为本发明放映机的部分壳体和散热器立体结构装配图；
图2为本发明放映机的部分壳体和散热器另一角度的结构装配图；
图3为本发明放映机的壳体的部分立体结构示意图；
图4为本发明放映机的壳体另一角度的部分立体结构示意图。
【具体实施方式】
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
请同时参图1-3所示，本发明提供一种放映机(未图示)，所述放映机包括壳体1、热源(图未示)及风扇(图未示)、散热器2。
壳体1具有收容空间10。壳体1包括贯穿其上设置的多个百叶窗 结构11。收容空间10依次通过所述散热器2和所述百叶窗结构11与外界连通。百叶窗结构11用于将所述散热器2与外界空气连通，该结构有利于所述散热器2直接将热量传递至外界。
在本实施方式中，百叶窗结构11包括多个通风孔110、多块叶片111以及两块连接片112。具体的，多个通风孔110分别贯穿壳体1。多块叶片111由壳体1的外表面向远离散热器2的方向倾斜延伸。每一叶片111与一个通风孔110相对设置，且叶片111向与其对应的通风孔110的正投影完全覆盖该通风孔110。两块连接片112由通风孔110的两个短轴边分别垂直延伸。两块连接片112分别和与该通风孔110对应的叶片111的相对两侧连接。百叶窗结构11的结构在将壳体1内部和外界的空气连通，同时，可以确保放映机的内部板卡、线材等不可见，且保证观察者无法从外部伸入简易的工具，即不能获取放映机内部的信息，也就是说，该结构满足DCI认证中的防篡改规定，从而使所述放映机满足DCI认证的要求。
热源安装于所述收容空间10内。热源产生的热量使收容空间10内的空气温度升高。在本实施方式中，热源包括灯泡和处理器芯片。
风扇安装于收容空间10内。风扇用于将收容空间10内的空气热量通过散热器2传递至外界。
散热器2固定于收容空间10内的。具体的，散热器2包括相互叠设且平行间隔设置的多块散热翅片21。其中，多个散热翅片21抵接于壳体1的一端共同形成出风面，多块散热翅片21远离出风面的一端共同形成进风面。散热器2为本技术领域常用的器件，因此，在此不做详细的描述。
在本实施方式中，出风面抵接所述壳体1且完全覆盖百叶窗结构11。也就是说，风扇转动时将收容空间10内的空气依次通过散热器2和通风孔110排出至壳体1外。具体的，风扇转动时将收容空间10内的空气依次通过散热器2和通风孔110排出至壳体1外。该结构不需要将壳体设置为迷宫结构，而且系统风道阻力较小，从而使风扇只可 以选择尺寸较小且较薄的规格型号，就可以获得足够的风量和风压，从而使所述放映机的通风状况佳、系统散热性能好且噪音低。因为所述放映机噪音低，进而使用户体验好。
在本实施方式中，多个通风孔110呈阵列排布。具体的，多个通风孔110呈多行排布或多列排布。该结构除了有利于阻挡观察者的视线，满足DCI认证中的防篡改规定，还有利于放映机散热通风。
在本实施方式中，在本实施方式中，通风孔110呈矩形，散热翅片21平行于通风孔110的长轴设置。该结构在保证实现阻挡观察者的视线，同时也有利于放映机散热通风。
在本实施方式中，叶片111由通风孔110的长轴边弯折延伸形成。也就是说，通风孔110在短轴方向通过叶片111阻挡观察者的视线。其中，多块叶片111相对于壳体1的倾斜方向相同。该结构使阻挡观察者的视线的效果更好。
请参图4所示，与叶片111连接的壳体1所在的平面与该叶片111之间夹角的角度定义为β。在本实施方式中，β为40°。该角度有利实现阻挡观察者的视线，使其不能直接观察或借助简易工具探测所述放映机内部器件。
为了可以有效实现阻挡观察者的视线，除了调整叶片111的角度，还可以调整通风孔110短轴方向的开孔高度,该开孔高度定义为H，H为所述叶片111远离通风孔110的一端距通风孔110的高度。具体的，散热翅片21的宽度与叶片111远离所述通风孔110的一端距通风孔110的高度呈正相关。即散热翅片21的宽度与H呈正相关。其中，散热翅片21的宽度是指散热翅片21由所述进风面到出风面的距离长度。正相关的体现在如果散热翅片21的宽度越大，叶片111开设的高度就可以越大，即可以满足好的通风效果的同时也可以保证阻挡观察者的视线。但是这会造成放映机体积变大，不利于小型化。经过权衡和优化，在本实施方式中，散热翅片21的宽度为40mm，叶片111远离通风孔110的一端距通风孔110的高度为4mm。以上设置的可以有效实现阻 挡观察者的视线。该尺寸结构有利于通风的同时，满足DCI认证中的防篡改规定，从而使放映机满足DCI认证的要求。
与现有技术相比，本发明的一种放映机通过壳体设有贯穿其上设置的多个百叶窗结构，并使散热器的多块散热翅片形成的出风面抵接所述壳体且完全覆盖所述百叶窗结构，从而使所述壳体内的所述收容空间依次通过所述散热器和所述百叶窗结构与外界连通，该结构不需要将所述壳体设置为迷宫结构，而且系统风道阻力较小，从而使所述放映机的通风状况佳、系统散热性能好且噪音低。另外，所述壳体设置的多个百叶窗结构具有遮挡光线直线射入的作用，该结构可以确保放映机的内部板卡、线材等不可见，且保证观察者无法从外部伸入简易的工具，即不能获取放映机内部的信息，也就是说，该结构满足DCI认证中的防篡改规定，从而使本发明的放映机满足DCI认证的要求。
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
