Air enters on one side, absorbs heat, and flows out again on the opposite side or the top. This airflow is controlled by the perforations in the sheet metal.  <\/p>\n<p>Punching tools can be used to create various geometries directly in the material. Round perforations ensure even air distribution while maintaining high surface stiffness. Slotted perforations increase the open area and thus the airflow. Gills and cutouts enable targeted airflow and combine forming and perforation in a single manufacturing step, which is particularly cost-effective in mass production.   <\/p>\n<p>The geometry of the perforations influences two opposing characteristics. A higher open area ratio improves airflow but simultaneously reduces the sheet metal\u2019s rigidity and increases the risk of spurious radiation. The optimal balance depends on the power dissipation of the installed components, the enclosure size, and the mechanical requirements. At BVS Blechtechnik, this optimization is routinely carried out in collaboration with customers as early as the quotation and design phases.<\/p>\n<\/div><\/section><\/p><\/div><\/p>\n<div class='flex_column av-15qvslo-6cbeb018a041771aca48d1773e122f5f av_one_full  avia-builder-el-12  el_after_av_one_full  el_before_av_one_full  first flex_column_div column-top-margin'     ><p>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-14k8q98-f04c757b95683c2ea1b40eaf8d7ce311\">\n#top .av-special-heading.av-14k8q98-f04c757b95683c2ea1b40eaf8d7ce311{\npadding-bottom:10px;\n}\nbody .av-special-heading.av-14k8q98-f04c757b95683c2ea1b40eaf8d7ce311 .av-special-heading-tag .heading-char{\nfont-size:25px;\n}\n.av-special-heading.av-14k8q98-f04c757b95683c2ea1b40eaf8d7ce311 .av-subheading{\nfont-size:15px;\n}\n<\/style>\n<div  class='av-special-heading av-14k8q98-f04c757b95683c2ea1b40eaf8d7ce311 av-special-heading-h2 blockquote modern-quote  avia-builder-el-13  el_before_av_textblock  avia-builder-el-first '><h2 class='av-special-heading-tag'  itemprop=\"headline\"  >Design Principles of EMC Shielding<\/h2><div class=\"special-heading-border\"><div class=\"special-heading-inner-border\"><\/div><\/div><\/div><br \/>\n<section  class='av_textblock_section av-12we8j0-e0702ac483c8d7c31c9f660a0f9300db'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p>Effective electromagnetic shielding requires continuous electrical conductivity throughout the enclosure. Any interruption, gap, or unpainted joint can significantly reduce the shielding effectiveness. Long, open slots are particularly critical, as they act like slot antennas and can radiate or couple electromagnetic interference. Shielding effectiveness decreases as frequency increases, while smaller opening geometries improve it.   <\/p>\n<p>From a design perspective, this can be addressed, among other things, by using overlapping edges at parting lines to prevent continuous gaps from forming. For moving components such as slide-in modules, contact studs embedded in the sheet metal ensure that a conductive connection is maintained even without rigid screw fasteners. If design measures alone are not sufficient, EMC strips are used as a supplementary measure.  <\/p>\n<p>Ventilation openings can also be designed to comply with EMC requirements. Arrays of many small individual holes significantly reduce the shielding effect less than single large openings, even when the total area of the openings is comparable. Relevant standards for IT equipment are EN 55032 and IEC 61000; shielding attenuation tests are conducted in accordance with DIN EN 61587-3. Compliance with these standards is a prerequisite for CE conformity and interference-free operation in data centers.<\/p>\n<\/div><\/section><\/p><\/div>\n<div class='flex_column av-10ytqho-6e1b0b5286a914013a8ca5674fd1b09d av_one_full  avia-builder-el-15  el_after_av_one_full  el_before_av_one_full  first flex_column_div column-top-margin'     ><p>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-10cdozg-8b84f2b9a255e28ad75516e7bdef631a\">\n#top .av-special-heading.av-10cdozg-8b84f2b9a255e28ad75516e7bdef631a{\npadding-bottom:10px;\n}\nbody .av-special-heading.av-10cdozg-8b84f2b9a255e28ad75516e7bdef631a .av-special-heading-tag .heading-char{\nfont-size:25px;\n}\n.av-special-heading.av-10cdozg-8b84f2b9a255e28ad75516e7bdef631a .av-subheading{\nfont-size:15px;\n}\n<\/style>\n<div  class='av-special-heading av-10cdozg-8b84f2b9a255e28ad75516e7bdef631a av-special-heading-h2 blockquote modern-quote  avia-builder-el-16  el_before_av_textblock  avia-builder-el-first '><h2 class='av-special-heading-tag'  itemprop=\"headline\"  >Acoustics and Vibration Damping in Sheet-Metal Enclosures<\/h2><div class=\"special-heading-border\"><div class=\"special-heading-inner-border\"><\/div><\/div><\/div><br \/>\n<section  class='av_textblock_section av-mo1hdsbs-60d7a5d1928cfd7c0f8961b1b0f7365f'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p>Server fans and drives generate continuous vibrations. Large, unsupported sheet metal surfaces can enter into resonance due to this excitation and become sources of noise themselves. This is not a rare problem, but one that is regularly underestimated in the design process.  <\/p>\n<p>The most effective measure involves the sheet metal itself: beading and embossing\u2014so-called stiffening formations\u2014increase the panel\u2019s stiffness without adding material and raise the natural frequency of the sheet metal surface. This shifts the resonance out of the typical excitation range of fans and drives. <\/p>\n<p>Where this is not sufficient, insulation mats are added; these are applied either over the entire surface or in specific areas on the interior walls of the enclosure to reduce structure-borne noise and sound transmission.

Therefore, without additional measures, a fully coated enclosure has neither a secure ground connection nor a functional equipotential bonding system. This is not a design flaw, but it must be taken into account early in the planning process.  <\/p>\n<p>From a process standpoint, the solution is clear. Contact surfaces and grounding tabs are defined and specifically masked off before coating to ensure these areas remain free of powder. The location and size of the areas to be kept free depend on the housing\u2019s eventual electrical wiring and are therefore coordinated closely with the customer. Grounding tabs are also integrated as fixed structural elements and recessed accordingly.   <\/p>\n<p>In practice, this step is more labor-intensive than it initially appears. If contact surfaces are not defined until after the production run has begun\u2014or even after coating\u2014the rework is time-consuming and often only possible to a limited extent.

In practice, however, this concept can only be fully implemented to a limited extent.  <\/p>\n<p>In practice, BVS has found that sliding mechanisms for enclosure lids and inserts, as well as snap-fit connections for removable assemblies and insert elements for plug-and-play components, have proven particularly effective. This simplifies the most common maintenance tasks without requiring the entire enclosure to be opened. However, such systems are generally not entirely tool-free.  <\/p>\n<p>Another design-wise measure is to reduce the number of different connection types. If all screw connections are the same size, the technician needs only a single tool for all tasks.

Round perforations offer a good balance between airflow and sheet metal stiffness and are suitable for a wide range of applications. Slotted perforations increase the open area but reduce the sheet stiffness to a greater extent. Gills and cutouts enable directed airflow and can be formed directly into the sheet metal using punching tools.

Ventilation openings are designed as arrays of holes with many small individual openings, as this maintains the shielding effect significantly better than a few large slits.
