Description

一种机柜 技术领域
本文涉及一种机柜，尤其涉及一种在机柜内背板上放置有单板的机柜。
背景技术
随着电信网网络的分组化及宽带化发展，在光传输网络中，对大容量电交叉需求不断提高，由于传统的单面交叉机架机柜(仅在机柜内背板的一面放置工作单板)，在容量上难以满足单板数量增长的需求，因此出现了双面插子架机柜(在机柜内背板的两面都放置工作单板)。双面插机架机柜需要在背板正反两面都放置单板，若正反两面的单板均横插(平行于机柜底面放置，下文称为横插单板)/竖插(垂直于机柜底面，下文称为竖插单板)，则可以在机柜相对两面设置进风口及出风口，如，针对竖插单板在机柜顶板及底板设置进风口及出风口上下直线吹风(下文称为上下风道)，针对横插单板在机柜的左板及右板设置进风口及出风口左右直线吹风(下文称为左右风道)；但是，为了提高单板集成度以增加机柜内可放置单板的数量，在背板正反两面放置的单板方向并不统一，如正面单板横插、反面单板竖插，此时就需要同时在机柜上设置上下风道及左右风道，由于吹风方向不一致，会导致机柜内风扇数量及设计难度大大提高。
因此，如何提供一种可降低单板集成度较高的机柜的风道设计难度的散热技术，是本领域技术人员亟待解决的技术问题。
实用新型内容
本实用新型实施例提供了一种机柜，该机柜内的散热风道前后散热，降低了单板集成度较高的机柜的风道设计难度。
本实用新型实施例提供了一种机柜，该机柜包括壳体、背板、及按照预设规则排列放置于背板上的单板；背板设置于壳体中，并把壳体隔离成两个部分，第一部分上设置有至少一个进风口，第二部分上设置有至少一个出风 口，背板上设置有至少一个通风口；所述进风口、通风口及出风口不在同一直线上。
可选地，上述实施例中的进风口和/或出风口设置于壳体内与背板相对的侧面上。
可选地，上述实施例中的进风口、通风口及出风口设置于壳体上或背板上对应单板间隙的位置。
可选地，在上述实施例中，第一部分内的单板平行于壳体的底面排列放置于背板上，所述进风口设置于壳体的侧面上。
可选地，在上述实施例中，第二部分内的单板垂直于壳体的底面排列放置于背板上，所述出风口设置于壳体的顶面、底面或与背板相对的侧面上。
可选地，上述实施例中的机柜还包括至少一个设置为通过进风口吸风的第一风扇，和/或至少一个设置为通过出风口排风的第二风扇。
可选地，上述实施例中的进风口、通风口及出风口位于同一平面上，并在该平面上形成Z字形，进风口及出风口位于Z字形的两个端点，通风口设置于Z字形的两个折点中的任一个。
本实用新型实施例提供的机柜，将散热风道的进风口、通风口及出风口设置为不在一个直线上，这样空气流从进风口进入、穿过通风口流到出风口，在保证了单板完全散热的基础上，空气流穿过背板，实现了机柜的前后散热，这些散热风道的进风口都可以设置在机柜的同一面(如前面板)上，降低了散热风道的设计难度。
附图概述
图1为本实用新型第一实施例提供的机柜的结构示意图；
图2为本实用新型第二实施例提供的机柜内散热风道的示意图；
图3为本实用新型第三实施例提供的机柜与相关技术机柜的对比示意图。
本实用新型的实施方式
本实用新型实施例提供一种非直线型的散热风道，这类散热风道比直线型的散热风道具有更大的散热面积，可以增加机柜的散热效率。
第一实施例：
图1为本实用新型第一实施例提供的机柜的结构示意图，由图1可知，在本实施例中，机柜1包括壳体、背板及按照预设规则排列放置于背板上的单板(图1未示出这些单板)，其中：
背板设置于壳体中，并把壳体隔离成两个部分，第一部分上设置有至少一个进风口11，背板上设置有至少一个通风口12，第二部分上设置有至少一个出风口13；所述多个(即一个或以上)进风口11、多个通风口12及多个出风口13不在同一直线上。
由图1可知，通过在第一部分设置进风口、背板上设置通风口、第二部分设置出风口，使得空气可以从机柜的第一部分进入，从机柜的第二部分流出，这样就可以对机柜两部分的单板都进行吹风散热，并且这些进风口、出风口都设置在同一个面板上(如前面板设置进风口、后面板设置出风口，下文称为前后风道)，降低了机柜的散热风道的设计难度；如，针对横插单板，可以在平行机柜底板的平面上设置本例所述的进风口、通风口及出风口，针对竖插单板，可以在垂直机柜底板的平面上设置本例所述的进风口、通风口及出风口。
第二实施例：
图2为本实用新型第二实施例提供的机柜内散热风道的示意图，由图2可知，在本实施例中，多个进风口11和/或多个出风口13设置于壳体内与背板相对的侧面(图2所示的前面板及后面板)上，第一部分内的单板平行于所述壳体的底面(底板)排列放置于背板上，多个进风口设置于所述壳体第一部分内的侧面(如图2所示的左、右板、前面板)上，第二部分内的单板垂直于所述壳体的底面排列放置于背板上，多个出风口设置于所述壳体第二部分内的顶面(如图2所示的顶板)、底面(如图2所示的底板)或与背板相对的侧面(如图2所示的后面板)上；其中：
参照图2内a—a截面视图可知，进风口11设置于第一部分的一侧，通 风口12设置于背板上靠近第一部分另一侧的部位；本实施例这样设置可以使得空气在进风口11与通风口12之间流经更大的面积，以增大单个散热风道的有效散热面积；
在图2内a—a截面视图中，出风口13设置于第二部分内与通风口12对应的位置；本实施例这样设置可以将带有热量的空气流尽快的从机柜内导出到外界环境中，以尽快散热。
在图2内a—a截面视图中，进风口11设置于第一部分对应第一部分内单板间隙一端的位置，通风口12设置于背板对应第一部分内单板间隙另一端的位置；
在一个可选实施例中，单板横插(平行于壳体的底面)于背板的正面，此时，如图3所示，进风段由壳体的左板、背板及隔板(图2未示出，设置于相连两单板的延伸方向，与壳体接触；在一个可选实施例中，若单板直接与壳体接触，则此时的隔板不存在，其直接由相连单板的相对面来担当)围成，散热段由横插单板的单板间隙、壳体的前面板及背板围成，出风段穿过背板在第二部分内出风；
在一个可选实施例中，在机柜11内设置多个平行于壳体底面设置的散热风道，多个进风段未设置隔板，多个进风段相通形成进风部分，进风部分由壳体11的左板、背板12、顶板及底板围成；
在一个可选实施例中，进风口11设置于前面板靠近左板的一侧，和/或左板靠近前面板的一侧；出风口13设置于壳体的后面板靠近壳体的右板的一侧，和/或壳体的右板靠近壳体的后面板的一侧；
参照图2内b—b截面视图可知，进风口11设置于第一部分的一侧(如图2所示的前面板的下侧)，通风口12设置于第一部分内与进风口11对应的位置；本实施例这样设置进风口11与通风口12，可以快速将冷空气流引导到需要散热的部分(如图2所示的第二部分)；
在图2内b—b截面视图中，出风口13设置于第二部分内与通风口12相对的另一侧(如图3所示的上侧)；本实施例这样设置可以使得空气在通风口12与出风口13之间流经更大的面积，以增大单个散热风道的有效散热 面积；
在图2内b—b截面视图中，进风口11及通风口12设置于第一部分对应第二部分内单板间隙一末端的位置，出风口13设置于第二部分对应第二部分内单板间隙另一末端的位置；
在一个可选实施例中，单板竖插(垂直于壳体的底面，如底板)于背板的反面；此时，进风段穿过背板进风，由壳体的底板、后面板及隔板围成，散热段由竖插单板的单板间隙、壳体的顶板、底板、后面板及背板围成，出风段穿过壳体11出风；
在一个可选实施例中，在机柜内设置多个垂直于壳体底面设置的散热风道，多个进风段未设置隔板，多个进风段相通形成进风部分，进风部分由壳体的底板、后面板、左板及右板围成；
在一个可选实施例中，进风段的进风口设置于前面板靠近底板的一侧，和/或底板靠近前面板的一侧；出风段的出风口设置于后面板靠近顶板的一侧，和/或顶板靠近后面板的一侧。
在一个可选实施例中，多个进风口、多个通风口及多个出风口设置于所述壳体上或所述背板上对应单板间隙的位置；本实施例这样设置进风口、通风口及出风口使得进风口、通风口及出风口形成的散热风道与单板间隙重合在一起，散热效果更好。
在一个可选实施例中，机柜还包括至少一个设置为通过进风口吸风的第一风扇，和/或至少一个设置为通过出风口排风的第二风扇；本实施例设置风扇，加快了散热风道内的空气流动。
在一个可选实施例中，同一散热风道的进风口、通风口及出风口位于同一平面上，并在该平面上形成Z字形，所述进风口及所述出风口位于Z字形的两个端点，所述通风口设置于Z字形的两个折点中的任一个；本实施例将同一散热风道的进风口、通风口及出风口设置在同一平面上，使得空气流动流畅，同时，本实施例提供的Z形结构设置简单，降低了机柜的制造成本。
第三实施例：
现结合一应用实例进行说明；在本例中，假定在机柜内背板的正面横插 5个单板，在背板的反面竖插4个单板(需要知悉的是，在实际运用中，背板两面所插的单板数量远远大于5个，并且相邻单板之间的缝隙很小，如仅相距2厘米左右，因此为了降低生产成本及设计负责度，并不会为每个单板缝隙设置单独的进风口、通风口及出风口，多个进风口相通形成一个进风区域，由一个风扇吹风，多个相邻通风口合并为一个通风孔，多个出风口相通形成出风区域，出风区域为网状结构)，而在本实施例中，则假定为每个单板缝隙设置单独的进风口、通风口及出风口；如下：
图3为本实用新型第三实施例提供的机柜与相关技术机柜的对比示意图，在图3中，背板正面横插有5个单板(单板两两形成4个单板间隙，最上及最下两个单板分别与机柜壳体也形成2单板缝隙)，背板反面竖插有4个单板(单板两两形成3个单板间隙，最左及最右两个单板分别与机柜壳体也形成2单板缝隙)；现假定，机柜设置有与单板缝隙的数量对应的散热风道；
在图3中，面板的视图方向是空气流动方向，如前面板、背板及后面板上设置的为前后风道，则前面板、背板及后面板的示意图为从机柜由前到后的所在面的剖视图，由图3可知：
在相关技术机柜中，针对背板正面横插的5个单板，需要在机柜的左板设置6个进风口，对应的在右板设置6个出风口；同时，针对背板反面竖插的4个单板，需要在机柜的顶板设置5个进风口，对应的在底板设置5个出风口；总共需要设置11对风口，并且所有的进风口
而本例提供的机柜，针对背板正面横插的5个单板，需在前面板的左侧设置5个进风口、对应的在背板的右侧设置5个通风口、在后面板的右侧设置5个出风口(最下面的缝隙由在前面板下侧设置的进风口散热)；针对背板反面竖插的4个单板，需在前面板的下侧设置4个进风口、对应的在背板的下侧设置4个通风口，在后面板的上侧设置4个出风口(最右面的缝隙由在后面板右侧设置的出风口散热)；
将两者进行对比可知：
在散热风道数量(进风口数量)方面：相关技术机柜需要6+5＝11个散热风道，而本例的机柜则仅需要5+4＝9个散热风道；即本例所提供的机柜降低 了散热风道的数量；
在散热风道方向(空气流动)方面：相关技术机柜需要同时设置上下风道及左右风道，进风面不在同一个面上，设计难度较大，而本例的机柜的所有散热风道仅为前后风道，进风面在同一个面上，设计难度较小；即本例所提供的机柜降低了散热风道的设置难度；
也即，本例提供的机柜在减少了散热风道数量的同时，还降低了散热风道的设计难度。
综上可知，通过本实用新型实施例的实施，至少存在以下有益效果：
通过在第一部分设置进风口、背板上设置通风口、第二部分设置出风口，使得空气可以从机柜的第一部分进入，从机柜的第二部分流出，这样就可以对机柜两部分的单板都进行吹风散热，并且这些进风口或出风口都设置在同一个面板上(如前面板设置进风口、后面板设置出风口)，降低了机柜的散热风道的设计难度；
可选的，将散热风道的进风口、通风口及出风口设置为不在一个直线上，这样空气流从进风口进入、穿过通风口流到出风口所流过的有效散热面积将大于散热风道为直线时的散热面积，增大了单个散热风道的有效散热面积，由于增大了单个散热风道的散热面积，在一定程度上就可以减少机柜内总散热风道的数量，相应的减少了风扇数量，降低了生产成本，并降低了风扇噪音；
可选的，通过将进风口与通风口或者通风口与出风口设置于某部分的相对两侧，更大程度的增加了散热风道的有效散热面积；
可选的，针对将进风口与通风口或者通风口与出风口设置于某单板间隙的两端，使得散热风道可以完全对该单板间隙的所有部分都进行散热，避免了散热盲区的出现。
工业实用性
通过本实用新型实施例的实施，在第一部分设置进风口、背板上设置通风口、第二部分设置出风口，使得空气可以从机柜的第一部分进入，从机柜 的第二部分流出，这样就可以对机柜两部分的单板都进行吹风散热，并且这些进风口或出风口都设置在同一个面板上，降低了机柜的散热风道的设计难度。
