Description

机柜用内嵌防尘通风散热装置 技术领域：
本实用新型涉及机柜配件技术领域，尤其是一种散热部件，具体涉及一种机柜用内嵌防尘通风散热装置。
背景技术：
机柜的防尘、通风和散热一直是个很重要的问题，比如，汽车制造的冲装、焊装、涂装和总装的四大工艺设备有配套的控制装置，可能是自动化的控制机柜或是智能型的控制机柜，这类机柜都有通风和防尘要求。
随着机柜主体技术的发展和机柜防护等级要求的提高，对防尘通风散热要求越来越高，原有的百叶窗式通风孔或纯百叶窗加防护网式的难以满足要求，存在通风散热与防尘的矛盾，即通风散热效果好的结构或单元其防尘效果就差，反之亦然。
实用新型内容：
本实用新型的目的是提供一种机柜用内嵌防尘通风散热装置，它设计合理，便于维护保养，防尘效果好，通风散热效果可以针对不同的要求选择相应的单元结构方式。
为了解决背景技术所存在的问题，本实用新型是采用以下技术方案：它包含内嵌护罩、过滤棉、散热孔、通风孔，内嵌护罩固定在机柜门板的内侧面，内嵌护罩上矩阵设置有通风孔，在门板与内嵌护罩形成的腔体内放置片状的过滤棉；门板上矩阵设置有散热孔，且散热孔在内嵌护罩的垂直投影内。
作为本实用新型的进一步改进，所述的散热孔所在区域在以内嵌护罩垂直投影几何中心为中心的80～95％区域内。
作为本实用新型的进一步改进，所述的过滤棉为片状，其厚度与门板和内 嵌护罩间形成的腔体厚度一致；优选无纺过滤棉或炭纤维过滤棉。
作为本实用新型的进一步改进，针对防尘和通风散热要求更高的场合，在内嵌护罩上安装风扇，目的是增强通风效果，内嵌护罩的上端固定安装有内嵌盖板，目的是为了提高内嵌护罩的稳定强度，同时也是为了增强通风效果。
作为本实用新型的进一步改进，所述的内嵌盖板与机柜门板间的连接可以是碰焊方式，或在门板上打螺柱，内嵌护罩与门板间垫密封垫片，通过螺母来固定。
作为本实用新型的进一步改进，所述的内嵌护罩的上端开有椭圆形缺口，是为了在维护过程中方便取出过滤棉进行清理或更换。
作为本实用新型的进一步改进，所述的门板也可以为机柜的侧板等其他位置或功能的壁板。
本实用新型的原理为：无风扇时，是自然通风，故从通风防尘的角度考虑可以不用内嵌盖板；有风扇时，是强制通风，内嵌盖板必须安装，强制通风时，如无盖板会因过滤棉的风阻比过滤棉与内嵌护罩间的风阻大，而形成气流优先从过滤棉与内嵌护罩内侧间的缝隙内流过，形成无效气流和气流的短路。
针对室内且粉尘不恶劣的情况，门板或壁板上可采用一般的矩阵圆孔或其他几何形状的孔如小方孔、椭圆孔；室内且粉尘恶劣的情况下，需要采用矩阵百叶孔。在不加风扇、自然通风的情形下，内嵌护罩上的孔可以是一般的矩阵圆孔或其他几何形状的孔如小方孔、椭圆孔，也可以是百叶式矩阵孔。
本实用新型中所述的机柜包括电力成套开关设备(柜)、自动化控制设备的机柜，特别是汽车制造专用装备配套的智能控制柜体的通风散热，如有防尘要求的涂装设备及机械化输送设备的控制机柜。
本实用新型具有以下有益效果：
1、过滤棉可以通过维护保养，方便对过滤棉进行清理或更换；
2、防尘效果好，通风散热效果可以针对不同的要求选择相应的单元结构方式。
