' ATTORNEYS United States Patent Int. Cl. F28c 1700,- Cj 1/08 U.S. Cl. 261-112 1 Claim ABSTRACT OF THE DISCLOSURE A plate assembly for liquid cooling installations comprising: a first liquid trickling plate disposed in a vertical plane; a second liquid trickling plate disposed in said vertical plane beneath said first plate; an intermediate trickling plate disposed in said vertical plane between said first and second plates; stationary mounting means engaging the ends of and supporting said first and second plates, said mounting means being independent of said intermediate plate; a plurality of horizontally-spacedapart connecting members engaging the lower edge of said intermediate plate and the upper edge of said second plate and supporting said intermediate plate on said second plate, said connecting members and said second plate being the sole means for supporting said intermediate plate; and separate connecting members connecting the upper edge of said intermediate plate to the lower edge of said first plate. The mounting means includes girders with the lower edges of the girders extending lower than the upper edge of the intermediate plate. The ends of the first, second and intermediate plates having channels. The intermediate plate is inverted relative to the first and second plates and the channels in the intermediate plate receives the lower edges of the girders mounting said first plate.

The present invention relates to the cooling of liquids where the liquids are allowed to run along or stream upon cooling surfaces. The invention is particularly concerned with plate assemblies for liquid cooling installations.

United States Patent No. 2,836,405, dated May 27, 1958 discloses and claims a plate assembly for liquid cooling installations comprising a plurality of horizontally extending substantially flat plates grouped in superposed and spaced relation in each of several vertical parallel planes; adjacent plates in said vertical planes forming horizontal rows; stationary supports freely engaging the ends of the plates of each row to hold the plates in suspended position; distancing connectors extending perpendicularly to said planes between each pair of an upper and a lower row of plates; an upper and a lower series of spaced vertical slots in each connector, said slots adapted to receive the border portions of the plates of said upper and lower rows respectively; the border portions of the plates of each upper row resting loosely in their respective slots having a width exceeding the thickness of said border portions and the border portion of the plates of each lower row being frictionally held in their respective slots having a width substantially equal to the thickness of said border portions.

The object of the present invention, is to provide a plate assembly for liquid cooling installations, the assembly comprising:

(i) A first liquid trickling plate;

(ii) A second liquid trickling plate mounted beneath said first plate;

(iii) Mounting means for supporting said first and said first plate;

(iv) An intermediate trickling plate interposed between said first and second plates and supported by said second plate; and

(v) Connecting means connecting said intermediate plate to said first and second plates.

The intermediate liquid trickling plate may be formed of a substantially rectangular plate which preferably has a width corresponding to that of either of the other trickling plates supported by the mounting means. When it is necessary, because of their span, for the mounting means, which may be in the form of girders, to have a height such that the lower face thereof extends lower than the upper edge of the intermediate plate, the intermediate plate is channelled at its upper corners. These channels may be adapted in shape to the projection of the mounting means, but the intermediate plate is preferably formed by one of the liquid trickling plates supported by the mounting means, the position of which has been reversed so that its upper edge now becomes its lower edge. Thus, groups of liquid trickling plates may be formed by the utilisation of a single shape of liquid trickling plate, this being an advantage which justifies the use of this arrangement also in the cases where the lower faces of the mounting means do not extend to a lower depth than the upper edge of the intermediate plates.

For a better understanding of the invention, and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which:

The figure is a front elevation, partly in section of the present invention.

In the drawings, there is shown a plate assembly for liquid cooling installations. In the assembly, liquid trickling elements 2', in the form of plates, are interposed between trickling elements 2, also in the form of plates which are supported laterally by girders 3 forming mounting means for mounting the elements 2. The trickling elements 2 are mounted on and supported by the lower elements 2 by the connection provided by connecting members 5'. The connecting members 5 connect the upper edges of the trickling eleemnts 2 to the lower edges of the upper elements 2.

The interposed trickling elements 2 may be formed by rectangular plates, the width of which corresponds to the width of the elements 2.

I claim:

1. A plate assembly for liquid cooling installations comprising:

a first liquid trickling plate disposed in a vertical plane;

a second liquid trickling plate disposed in said vertical plane beneath said first plate, each of said first and second plates having a downwardly facing shoulder portion at each end formed by a channel; an intermediate trickling plate disposed in said vertical plane between said first and second plates;

stationary mounting means engaging the ends of and supporting said first and second plates, said mounting means being independent of said intermediate plate and including first and second pairs of horizontal girders extending transversely of said vertical plane, the shoulders of said first plate resting on said first pair of girders and the shoulders on said second plate resting on said second pair of girders, the lower edges of said first pair of girders extending lower than the upper edge of said intermediate plate, and the ends of said intermediate plate being channelled similarly to the ends of said first and second plates, said intermediate plate being inverted relative to said first and second plates and the channels in said intermediate plates receiving the lower edges of said first pair of girders;
