  • Roll-bond evaporators are known in the prior art for use in for example domestic refrigerators. In such refrigerators the sheet of the roll-bond evaporator is typically bent into a U-shape to form a cooling box. Thus the conduits formed in conventional roll- bond evaporators are directed in such a way to allow for bending of the sheet along where the corners of the box are to be formed.
  • Roll-bond evaporators are formed by bonding together two thin sheets of aluminium so that the two sheets become a single unitary sheet of aluminium.
  • the conduits are formed by masking the desired conduit paths before the two thin sheets are formed together so that, once tiie two sheets are formed into a single unitary sheet the masked path remains thereby separating the two sheets along the length of the masking.

  • Another factor in the operation of the atmospheric water generator according to the present invention is controlling the frosting of the roll-bond evaporators so as to minimize and advantageously avoid, the build-up of frost or ice on the surfaces of the roll-bond evaporators.
  • One method by which this is accomplished is running the refrigeration assembly at a lower capacity, for example, by reducing the available power from the motor.
  • a motor which only delivers approximately 1/16 th of a horsepower per roll-bond evaporator minimizes the formation of frost or ice so as to maximize the formation of moisture droplets on the surfaces of the roll-bond evaporators.
  • the surfaces 22b of roll-bond evaporators 22 may be formed with protrusions, or "scales" 42 or other flow-tripping devices such as would be known to those skilled in the art of fluid mechanics, which would rapidly trip a laminar flow into a turbulent one.

Abstract

L'invention porte sur un générateur d'eau atmosphérique qui comprend un système de réfrigération. Les évaporateurs peuvent être des évaporateurs à tubes intégrés. Les ventilateurs coopèrent avec un radiateur et les évaporateurs pour induire un courant de débit d'air à partir d'air ambiant dans et à travers, tout d'abord, le condenseur, et ensuite, le radiateur. Le courant de débit d'air est refroidi par l'évaporateur lorsque le courant passe à travers l'évaporateur. Le courant refroidi d'air passe ensuite à travers une section de dissipation chauffée du radiateur. Les voies d'aérage entre les évaporateurs dans le réseau sont suffisamment longues pour que les courants d'air deviennent mélangés de manière turbulente. Les évaporateurs peuvent être plans. Des surfaces dirigées de manière opposée d'évaporateurs adjacents peuvent comprendre des chariots de déversement d'écoulement turbulent pour changer un écoulement laminaire dans les voies d'aérage en un écoulement turbulent. Les chariots de déversement d'écoulement turbulent peuvent comprendre des saillies formées sur les surfaces dirigées de manière opposée ou des feuilles métalliques entrelacées dans les voies d'aérage entre les évaporateurs.
