Definitions

  • the chief object of the invention is to provide an apparatus of the kind mentioned in the introduction, with a configuration such that good heat transfer and favourable current conditions are afforded in its use as an evaporative heat exchanger, the configuration especially enabling the useful air current to have an horizontal flow direction for the apparatus readily to be incorporated in ventilation plants, where the normal duct system is horizontal.
  • the contact body 10 illustrated in Figure 1 is used as an indirect heat exchanger for a useful air current flowing substantially horizontally through the contact body which air is to be cooled and is supplied to the inclined end wall surface 28 illustrated in Figure 1 constituting the inlet to a first duct system in the contact body 10 the useful air current flowing through this duct system in the longitudinal direction of said ducts or gaps, which are separate from adjacent ducts or gaps in a second duct system passed through by a cooling air current.
  • the contact body 10 may be made up from a plurality of flat plates 11-15, these being put together with flange-like stiffe ⁇ ning and surface magnifying means therebetween, as illu ⁇ strated in Figure 5, these means being in the embodiment shown corrugated metal sheets or foils 16.
  • the corruga ⁇ tions in the sheets 16 constitute the ducts for the useful air which is to be cooled in the contact body 10, the sheets 16 being oriented with their corrugations exten ⁇ ding in the flow direction of the air.
  • the corrugated foil or sheet 16 thus defines the width of the ducts or gaps in the contact body through which the useful air passes.
  • the corrugations of the sheet 16 must be in good heat conductive contact with the surfaces of the flat plates 11-15. When there are several layers, the crests of the corrugations shall be immediately opposite each other which increases the stability of the body and gives a shorter path for heat conduction.
  • the plates 11- 15 are preferably made rectangular, but at one vertical end, the left one in the Figures, they are given the shape preferably of an unequal sided triangle to form a connection part where the shorter side 26 constitutes the outlet from the second duct system 18, while the longer side 28 constitutes the inlet to the duct system 16.
  • a sealing strip 30 is disposed between the plates 11, 15 contiguous to the ducts 18, as illustrated in Figure 6.
  • the spacers 32 that determine the width of the ducts 18.

Abstract

Un appareil permettant un refroidissement indirect par évaporation d'un courant d'air utile comprend un corps de contact (10) constitué de couches entre lesquelles sont disposés les systèmes de conduit. Il y a deux systèmes de conduit séparés, l'air utile destiné à être refroidi passant à travers un système (16), tandis qu'un courant d'air de refroidissement passe à travers l'autre système (18). Le refroidissement s'effectue par évaporation de l'eau dans l'autre système (18). Les organes formant les conduits (16, 18) dont les deux systèmes sont disposés de sorte que les courants d'air utile et de refroidissement s'écoulent horizontalement, tandis que les organes (24) fournissant de l'eau à l'autre système de conduit (18) sont disposés au sommet du corps de contact (10), permettant à l'eau de s'écouler verticalement vers le bas dans ce système (18).
