Abstract
A plate cooler for cooling a fluid made of a plurality of superposed pairs of spaced plates sealed at their margins by side and end plates to form fluid flow channels and connected by lateral plates. The spaced plates and lateral plates are provided with aligned fluid flow openings forming a fluid flow conduit connected to a fluid input and output. The cooler is preferably made of aluminum or an aluminum alloy and is assembled by vacuum welding.
Description
- 1. Field of the Invention
- The present invention relates to coolers in general and to a plate cooler for cooling hydraulic oil, in particular.
- The cooler is preferably made of top and bottom plates which, between them, hold a substantially parallelepiped packet of spaced plates forming fluid channels with cooling fins being interposed between adjacent fluid channels, the ends of the fluid channels being connected to fluid distribution channels which in turn lead to fluid input and output conduits.
- 2. The Prior Art
- The fluid channels in conventional plate coolers of this general type are as a rule constructed of flat tubes which are closed at their ends by cuboid inserts. Such structures suffer from the drawback of the manufacture of the flat tubes and, indeed, of the entire cooler being complex and expensive.
- It is an object of the invention to avoid this drawback and to provide a plate cooler of the kind referred to supra which is not only of a simple structure, but which may also be easily connected.
- Other objects of the invention will in part be obvious and will in part appear hereinafter.
- In the accomplishment of these and other objects the invention provides for a plate cooler in which each of the fluid channels is formed by the two spaced plates as well as by side and end plates arranged therebetween. Cooling fins are arranged between two lateral plates arranged in the area of the distribution conduits and provided with a fluid flow-through opening, the lateral plates being of substantially the same height as the fins. The plates, the side plates, the end plates, the lateral plates, the bottom plate and the cover plate are assembled into a packet by vacuum welding. Preferably, at least the plates are made of aluminum or an aluminum alloy.
- The novel features which are considered to be characteristic of the invention are set forth with particularity in the appended claims. The invention itself, however, in respect of its structure, construction and lay-out as well as manufacturing techniques, together with other objects and advantages thereof, will be best understood from the following description of preferred embodiments when read in connection with the appended drawings, in which:
- FIG. 1 is a schematic side view of the plate cooler in accordance with the invention;
- FIG. 2 is a schematic front view of part of the plate cooler;
- FIG. 3 is a sectional view of the plate cooler along line III-III of FIG. 1;
- FIG. 4 s a sectional view of the plate cooler along line IV-IV of FIG. 2; and
- FIG. 5 is a sectional view of the plate cooler along line V-V of FIG. 2.
- As shown in FIGS.1 to 4, the plate cooler for use with liquids, and more particularly with hydraulic oil, is preferably made of aluminum or an aluminum alloy and is provided with a
parallelepiped packet 3 of spacedplates 4 disposed between abottom plate 1 and acover plate 2.Fluid channels 7 are formed by pairs of spacedplates 4 andseparate side plates 5 andend plates 6 arranged between theplates 4. At their ends, thefluid channels 7 are connected tofluid distribution conduits 8 which lead to input and output channels structures ascorner connectors 9, for instance.Cooling fins 10 are interposed between neighboringfluid channels 7. More particularly, thecooling fins 10 are positioned between twolateral plates 12 of substantially the same height as thecooling fins 10 and which are positioned in the area of thedistribution conduits 8 and provided with a fluid flow-throughopening 11. - The
bottom plate 1, thecover plate 2, theplates 4, theside plates 5, theend plates 6 and thelateral plates 12 are made of coated aluminum or of an aluminum alloy. They are assembled together as apacket 3 by vacuum welding which renders the cooler highly resistant to hydraulic stresses, permanent loads and vibrations. - Those skilled in the art will understand that within the frame of the general concept of the invention the described embodiment may be altered in several different ways.
