Definitions

  • the invention relates to a self-supporting, essentially cuboid vacuum container, which is particularly thin-walled, and its use in particular for adsorption devices.
  • a vacuum tank is usually necessary because e.g. Water can be used as a refrigerant and accordingly low pressures are required.
  • the known classic vacuum containers have a mostly cylindrical main body, which is formed inter alia by a metal jacket, which has at least a thickness of 4 or 5 mm. Such vacuum containers are very heavy compared to other parts of sorption machines.
  • the internals in these vacuum containers are often cuboid, such as fin heat exchangers as adsorber, condenser or evaporator. For these reasons, the space provided by the vacuum container is often not effective to use. This is disadvantageous for the power density and for the material costs, but also for the thermal mass (see FIG. 1).
  • an adsorber-desorber unit comprises a thermally conductive receiving body which is in heat-conducting connection with a heat exchanger.
  • This known receiving body fulfill two functions, namely the meübertragung between heat exchanger and sorbent material and on the other hand, the production of a stable structure of the adsorbent-desorber unit. It is described that with this stable structure it is possible to make the wall of a common housing of the sorption heat pumps particularly thin, since this unit no longer needs to impart additional stability, but only the sealing of the interior with the adsorber-desorber unit and the condenser - Evaporator unit is used to the environment.
  • the outer wall is designed as a thin sheet metal casing, which has a small wall thickness, that it rests on the adsorber-desorber unit or the condenser-evaporator unit and is supported by the latter, in particular after application of negative pressure. Since the thin sheet metal sheaths are supported and supported by said units, they are referred to as a non-self-supporting vacuum envelope or a non-self-supporting vacuum envelope.
  • Self-supporting containers are widely known to the person skilled in the art (JP 63280964 A, GB 2303694 A, DE 10 2007 003 077 A1, DE 10 2006 032 304 A1). These known, partially self-supporting vacuum containers have an annular cross-section and are usually joined together by a plurality of annular shell segments.
  • JP 63280964 A describes a cylindrical, self-supporting vacuum container.
  • GB 2303694 discloses an ultralight, laminated vacuum plastic container.
  • Self-supporting, thin-walled tanks are also provided in the construction of fuselage structures of aircraft or tank structures of rockets, which, however, can not be used as vacuum containers. The majority of known pressure vessels are cylindrical if they are self-supporting; Vacuum containers are predominantly cylindrical.
  • cuboid vacuum container with outer walls with wall thickness of at least 5 mm, which are additionally supported with internal stiffening angles.

  • the thin-walled vacuum containers have outer walls or container walls with a wall thickness of less than 0.8 mm, preferably less than 0.7 mm, and particularly preferably less than 0.6 mm.
  • Self-supporting vacuum containers with such small wall thicknesses of the outer walls are particularly advantageous, since they are very light and yet are able to withstand the mechanical stresses caused by the vacuum forces. It was completely surprising that can be provided with the above-mentioned inventive and especially with the preferred wall thicknesses vacuum container, which under the forces of the vacuum (pressure or negative pressure, depending on which pressure is taken as a reference, a negative pressure in a container leads z B. to an increased pressure acting on it) dented and yet fully functional.
  • the calculated denting means that the vacuum containers are resistant to implosion, but clearly deform under the influence of negative pressure.
  • the average person skilled in the art has hitherto assumed that such vacuum containers can by no means be used for use in sorption machines, in particular adsorption machines.
  • the object according to the invention can be achieved by means of a thin-walled, self-supporting, cuboid vacuum container, which preferably has struts, profiles or angles or, in particular, outside or inside beads.
  • No thin-walled self-supporting cuboid vacuum containers for sorption heat pumps are described in the prior art.
  • the containers according to the invention are lighter and less expensive than those of the prior art and have container walls with a thickness of ⁇ 3 mm, ⁇ 2 mm, ⁇ 1 mm. In these self-supporting cuboid vacuum container and unstable internals can be used, since they do not have to absorb the vacuum forces.

  • the receiving body imparts stability to the adsorber-desorber unit
  • the interior of the common housing is subjected to a negative pressure and the common housing is designed as a thin-walled, self-supporting, cuboid vacuum container according to the invention, so that the collapse forces generated by the negative pressure can lead to a deformation of the vacuum vessel, but not that the vacuum container implodes, wherein the deformation of the vacuum container does not cause the collapse forces generated by the negative pressure on the receiving body, the heat exchanger shear, the evaporator, the condenser and / or the condenser-evaporator unit are derived,
  • a deformable, d. H. implosion-resistant vacuum container provided in particular for adsorption chillers.
  • the heating forces generated by the negative pressure are not dissipated to the adsorber-desorber unit, the condenser, the evaporator and / or the condenser-evaporator unit or to the receiving body, since the vacuum container is a self-supporting vacuum container according to the invention.
  • the vacuum container is a self-supporting vacuum container according to the invention.

  • Another form of a substantially cuboid vacuum container would be, for example, a container in which z. For example, two elongated outer walls are only substantially parallel. IeI are spaced from each other. The skilled person would also call such a container cuboid.
  • vacuum containers for sorption machines in particular for adsorption chillers can be either tubular or not self-supporting vacuum tank, so that it was completely surprising that self-supporting vacuum tank with a wall thickness of less than 3 mm, preferably less than 2 mm and more preferably less than 1 mm can be provided without the collapse forces of the vacuum vessel generated by the negative pressure being discharged onto the receiving body, the heat exchanger and / or the condenser-evaporator unit.
  • sorption preferably adsorption
  • a vacuum container which is significantly deformed by the negative pressure.
  • a significant deformation is a deformation that the average expert perceives as significant in the form of dents or indentations. Deformation thus does not mean deformation of the outer walls of the vacuum vessel occurring only in the tenth of a millimeter range, but rather a visualization of the vacuum vessel that can be visually perceived without further aids.
  • At least one stiffening agent is attached in at least one outer side of the container wall in a particularly preferred embodiment of the invention, this surprisingly leads to a good stiffening of the self-supporting vacuum container, if it is used in particular for adsorption refrigeration machines.

Since the intermediate wall by the stiffening means less by the different acting pressures (due to the process, it may come in the chambers that are formed by the intermediate wall, come to different process pressures), the preferred vacuum container according to the invention can be particularly well for sorption, especially adsorption, used.
