Definitions

  • the invention relates to universally applicable, compact computer housing of a different construction and arrangement, with no restrictions or reductions, i.e. Using only commercially available standard components in the basic version, up to 50% volume savings compared to previous standard computer housings is possible and the housing is still very easily accessible despite the compact dimensions.

  • the number of storage media devices is a result of the compromises and trade-offs between the largest possible motherboard sizes to be used in the wide range of applications and the acceptable size of the basic case, ie between universality and compactness; in this regard, the optimal basic dimensions are determined using a few case studies. Since the depth of the case has already been determined by the standard standard width (12 "/ 305mm) of the ATX mainboard, only the calculations for the height and width of the case to be determined are shown in the basic version in the following exemplary embodiments (see Fig. 2 and 3):

  • the housing base (700) which can be opened for accessibility, as shown in Fig. 4, can be attached to the edge B (the main part of the board) with the hinge strip (503) and accordingly to the edge D (the part of the device) with the hinge strip (504) the intended expansion module (600) is attached.

  • the dimensions of the expansion modules should assume the width and depth of the housing, while the height can be varied as required.
  • the covering device should have EM conductivity where possible; this cover can therefore either be made entirely of metal or of another material with a conductive coating which has electrical contact with the rest of the housing.
  • the cable duct can be the housing base (700) as well as for the integration of e.g. Loudspeaker box can be used and designed accordingly (see Fig. 4 and 5).
  • the housing foot - at least at one of the edges - should be provided with a hinge mechanism (503) or other opening mechanisms, so that access to those inside is possible at all times Cable connections can be guaranteed.

As in Chap. II.7. c justified, only one woofer is used here.
  • a (triangular) plane formed by 3 (instead of 4) points as a support surface has certain advantages, such as the easy adjustability of the angle of inclination over only one point, e.g. using a single adjusting screw at the front support point (705 - Fig. 5). The relevant meaning of the angle of inclination will be described later in Chap. II.8 shown.
  • a loudspeaker sound reproduction device
  • most of the loudspeaker boxes are unfortunately still separated from the computer system as a separate extra part, with the exception of the so-called multi-media monitors, which contain integrated loudspeakers.
  • Each extra part - separate speaker boxes standing next to the computer system - requires additional space on the desk; the reduction in the contact surface of the new computer case achieved would be severely impaired by separate extra boxes.
  • Fig. 5 shows, e.g. a flat / oval loudspeaker version (711) with a diameter of less than 200mm foot width, which is attached at an angle, and two or more small loudspeakers (whose diameter is less than 50mm foot height) integrated as a mid-tone / tweeter for the two stereo channels become.
  • An alternative option is to attach the loudspeakers (as well as other devices, such as an Internet camera, microphone, etc. for video conferences) in the housing cover (601 - Fig. 4) as an expansion special module (see Chapter II. 6).
  • An advantage could be used in this case, since the larger content of the entire computer housing - connected to the interior of the housing due to the existing cable openings - can be used as a resonance volume.
  • the additional function of the housing foot (see Fig. 5) as a channel for fresh air supply and also for heat dissipation from the immediate power supply unit is described at the end of the following chap. II.8 treated.
  • the top of the housing (see Fig. 4), which is intended for expansion modules (Section II.6), also offers numerous design options for various heat dissipation devices.
  • Computer components with the greatest heat development are generally the CPU, the power supply and the mainboard as well as the built-in add-on cards; compared to these, components such as floppies, hard drives, CDROMs etc. are negligible.
  • the CPUs single / dual
  • the ATX power supply are arranged one above the other in such a way that the power supply fan either leads the warm indoor air to the outside via the power supply, i.e. the power supply is cooled with warmer CPU air or blown inwards onto the heat sink of the CPU, i.e. the CPUs are cooled with warmer PSU air.
  • the usual standard version of a free-standing CPU cooler does not have the most effective function, since its fan has only partly circulated the hot air generated in the interior, and due to the short distance between the inlet and outlet, the hot air deflected by the heat sink immediately returns is sucked in.
  • a possible reduction could e.g. through an additional, extended air duct, which is attached tightly to the inlet opening of the CPU fan and screwed directly to the CPU heat sink; The following cases should be considered for the suction point of this air duct.
  • a strong noise is usually caused by strong air turbulence and is often amplified by resonances; therefore, this aspect should always be considered when designing.
  • the location between the CPU mounting bracket and the immediate AGP graphics card which is about 15-20mm apart.
  • the fresh air coming in and drawn in from the housing foot can simultaneously cool the AGP graphics card, if the duct wall is designed as an open U-shape and is attached to the graphics card with the U opening.
  • the suction point of the extra CPU duct can be attached directly in front of the inflatable power supply unit blower, so that an increase in the air duct flow for the CPU cooling arises, since the two fan blowers (the CPU and the power supply unit) have their effects Mutually reinforcing the transport of air matter; there is also a certain amount of redundancy if one of the two fans fails.
  • CPU fans / coolers are to be used is left to the manufacturer and is not the subject of the invention.
  • heat accumulation is nothing other than the formation of locally static heat gradient layers without the possibility of dynamic exchange of the air material (eg by blocked supply or discharge); on the other hand, the so-called “chimney effect” is - viewed locally - still a thermal gradient layer formation, however, there is a constant, dynamic exchange of the air matter. Every horizontal surface lying parallel to the thermal gradient layer therefore always favors heat build-up if, for any reason, the dynamic exchange of the air matter is impeded.
  • the gaps (801) between the add-on cards to be installed must always be sealed with the I / O blinds leading to the outside due to EM shielding; However, due to the sealing, these gaps form a so-called "dead water” point for air flow, i.e. a potential heat accumulation point.
  • the detachable housing cover (601) at the highest point of the housing serves not only for the purpose of optically covering the connection mechanisms located there, but also at the same time for EM shielding of the recessed openings for cable feedthroughs of the expansion modules.
  • These existing opening connections allow and facilitate the implementation and attachment of various air discharge devices in the housing cover, since warm air can rise up through this opening.
  • the warm air with the highest temperature will collect in this highest-lying lid space, ie collecting containers for the rising warm air, and can be removed directly to the outside via air discharge devices, such as perforations with passive or active cooling units, etc.
  • a special cooling unit such as a large-volume heat exchanger or the like, if necessary, can also be attached as an expansion module.
  • a rotation or inclined inclination of the entire housing including the contents which are e.g. is easy to implement with a sloping housing foot (see Fig. 5), provides - viewed from various aspects - additional advantages in heat dissipation, as will be analyzed and justified below.
  • a dynamic warm air movement (so-called convection), which has arisen automatically, is only due to the differences in air density, i.e. caused by the temperature / density gradient.

Since air density depends on temperature and warmer air (with lower density and higher temperature) always moves vertically upwards, the vertically emerging warm air convection current should be able to pass as freely as possible.
  • a horizontal surface that is parallel to the gradient layers and therefore perpendicular to the direction of flow creates the greatest flow resistance and favors a static density gradient without material exchange (so-called heat build-up) rather than an inclined one that is not parallel to the gradient layers Area.
  • this housing is by no means limited to the exemplary embodiments and applications described here with Intel / AMD / IBM CPUs etc., but also for all other computer mainboards with RISC, PowerPC, Alpha CPUs and many more. used; in this case, only the half of the mainboard of the housing needs to be modified, whereas the half of the device can be retained, since it only contains standard, standard storage media devices that are used in almost all computer systems.

Abstract

Le développement croissant des moniteurs plats à cristaux liquides et TFT souligne la nécessité de réduire la place occupée sur les bureaux et également de réduire la taille des systèmes informatiques/postes de travail de bureau qui sont encore volumineux. En outre, avec les boîtiers de PC habituels, les raccordements/connexions de câble extérieurs placés à l'arrière sont ouverts, visibles et, tant optiquement que techniquement, souvent dérangeants. L'invention concerne donc un boîtier d'ordinateur universel, compact, permettant un accès facile, comportant un pied servant à la fois de canal de passage de câble et d'aération, destiné à l'intégration de composants standards du commerce. Ce boîtier est constitué de deux moitiés de boîtier présentant un agencement/groupement des composants approprié (une moitié comportant la platine principale et l'autre les appareils), lesquels peuvent être rapprochées ou écartées l'une de l'autre par basculement, fermées, démontées et, en outre, agrandies. Un tel boîtier permet d'obtenir un gain de volume de 50 % et une surface d'appui correspondant environ à la grandeur spécifiée par DIN A4 ou inférieure à celle-ci. Sur ce boîtier de base, divers modules d'agrandissement peuvent être montés. Les domaines d'utilisation de ce boîtier ne sont en aucun cas limités à des PC comportant des unités centrales Intel/AMD, mais ils couvrent aussi tous les autres systèmes informatiques (systèmes RISC entre autres); dans ce cas, seule la moitié de boîtier comportant la platine principale doit être modifiée, par contre la moitié de boîtier contenant les appareils qui sont des appareils à mémoires standards du commerce se trouvant dans presque tous les systèmes informatiques peut être conservée. La complexité et les coûts peuvent ainsi être réduits.
