A radiator (1) presenting two side by side radiator elements (2), each presenting two manifolds (4) and a number of columns (5) hydraulically connecting the manifolds (4) of the same element. The radiator (1) also presents a wall (6) of the manifolds of a first element contacting a corresponding wall (6) of the manifolds of the second element, the contact portion of the walls (6) of the manifolds being defined along a flat portion of the walls; a recess (7) formed in the flat portion of the walls at the ends of each manifold, to define a duct between the side by side manifolds; a weld (8) along the edge of the recesses between the side by side walls, so as to define a single manifold at the ends of each pair of manifolds; and a plate (11) fitted in fluidtight manner to the end of the single manifold.
Description
- The present invention relates to a perfected radiator presenting two radiator elements, each comprising two manifolds connected hydraulically by a number of columns.
- Known radiators of the above type present, at each axial end of the manifolds of a first element, a body for externally connecting the manifolds hydraulically to those of the second element. Such a system involves considerable cost, mainly due to the machining required for forming the ducts in the hydraulic connecting bodies, which cost is further increased by the number of seals required.
- It is an object of the present invention to provide a perfected radiator featuring an efficient, low-cost system for hydraulically connecting the two radiator elements.
- According to the present invention, there is provided a perfected radiator comprising two side by side radiator elements, each presenting two manifolds and a number of columns hydraulically connecting the manifolds of the same radiator element; characterized in that it comprises:
a wall of the manifolds of a first said element contacting a corresponding said wall of the manifolds of the second said element; the contact portion of said walls of the manifolds of said elements being defined along a flat portion of said walls;
a recess formed in said flat portion of said walls, at the axial ends of each said manifold, to define a duct between the side by side manifolds;
a weld formed along the edge of said recesses between said side by side walls, so as to form, at the axial ends of each pair of side by side manifolds, a single manifold, the end of which presents an inner contour defined by the inner contours of said side by side manifolds, and by the front portion of said recesses; and
a plate fitted in fluidtight manner to the end of said single manifold. - A preferred, non-limiting embodiment of the present invention will be described by way of example with reference to the accompanying drawings, in which:
- Figure 1 shows a front view of a radiator in accordance with the teachings of the present invention;
- Figure 2 shows a larger-scale exploded view of a portion of the Figure 1 radiator;
- Figure 3 shows a section of the Figure 2 portion;
- Figure 4 shows a side view of the Figure 2 portion with one component removed.
- Number 1 in Figure 1 indicates a radiator comprising (Figure 2) two
radiator elements 2, each presenting twomanifolds 4, and a number ofcolumns 5 hydraulically connecting the manifolds of thesame element 2.Elements 2 are arranged side by side so that awall 6 ofmanifolds 4 of afirst element 2 contacts thecorresponding wall 6 ofmanifolds 4 of thesecond element 2; the contact portion ofwalls 6 ofmanifolds 4 of the twoelements 2 being defined along a flat portion ofwalls 6. - As shown in Figures 2 to 4, at the axial ends of each
manifold 4, a recess 7 is formed, via material removal, in the flat portion ofwalls 6; and, along the edge of recess 7, a weld 8 is formed between the two side byside walls 6 so as to mechanically connect, and define a duct between, the two side byside manifolds 4. In other words, at the axial ends of each pair of side byside manifolds 4, there is formed a single manifold, the end of which presents an inner contour defined by the inner contours of side byside manifolds 4 and by the front portion of the two recesses 7. - Said end of the single manifold is fitted inside with a
plate 11 presenting a peripheral contour substantially similar to the inner contour of the single manifold. More specifically, the outer face ofplate 11 is flush with the outer edge of the axial end of the single manifold. The rear portion of recesses 7 is of course unaffected byplate 11 and therefore provides for hydraulically connecting the two side byside manifolds 4. To seal the single manifold, aweld 12 is then made between its inner edge and the peripheral edge ofplate 11, which presents a threaded central throughhole 13 terminating at the rear portion of recesses 7 and for in-service connection of hydraulic joints and valves. - The advantages of the present invention will be clear from the foregoing description.
- In particular, it provides for a two-element radiator featuring a hydraulic connecting system between the manifolds which is both efficient and cheap and easy to produce.
- Clearly, changes may be made to radiator 1 as described and illustrated herein without, however, departing from the scope of the present invention.
- In particular,
manifolds 4 may differ in design from those shown herein, providingmanifolds 4 of afirst element 2 present awall 6 contacting acorresponding wall 6 ofmanifolds 4 of thesecond element 2 along a flat portion in which to form recesses 7; in which case, of course, the outer contour ofplate 11 will substantially match the inner contour of the single manifold formed by the two side byside manifolds 4 of the twoelements 2.
