ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an arrangement for connecting tubes to the distributor or manifold section of an apparatus for treating a liquid, particularly an oil/air cooler of the kind usually incorporated in the return path of an oil operating circuit. The cooling elements of the cooler through which the oil is flowing and which are assembled as a parallelepiped package known also as a core usually consist of aluminum plates or staves surrounded by air fins, and are connected to a box-like distributor section or tank extending across the upper surface of the package. Furthermore, the cooling elements are affected by a fan mounted adjacent thereto.
2. The Prior Art
In oil/air coolers of the kind hitherto known, the connector sockets for usually tubular input and output conduits in the distributor or head section of the parallelepiped cooler are of predetermined cross-section and extend at a right angle from the end of the cooler to the outer surface of the distributor section. This requires not only to stock various oil/air cooler models of differently dimensioned connectors, but in many instances it also complicates the installation of an oil/air cooler. Moreover, a relatively large space is needed for connecting the conduits. The mentioned problems also arise in liquid distributors for liquids other than oil, such as, for instance, for the processing of milk and the like.
OBJECT OF THE INVENTION
It is an object of the invention to avoid the mentioned deficiencies and to provide a connector arrangement of the kind referred to above which is suitable for different applications and which for different tubing connectors necessitates stocking of but one model of liquid processing device.
SUMMARY OF THE INVENTION
The invention is embodied in a device for connecting tubular conduits to the distributor or manifold section, also known as a tank of a liquid processing apparatus of the kind provided with a so-called core of aluminum plates or staves assembled as a parallepiped package and with a box-like liquid distributor section or tank extending across a front surface of the package. In accordance with the invention, a corner portion of the parallepiped distributor section is cut off to form a substantially equilateral surface having an opening therein for providing a liquid passage and that a substantially pyramidal hollow adapter attachment is provided which may be placed upon the triangular surface, the adapter attachment being provided with a base provided with a liquid passage corresponding to the liquid passage of the triangular surface and, in one of its side-walls, with a connector opening for a tubular conduit.
The invention makes it possible to mount the adapter attachment at different dispositions or orientations on the flattened portion such that depending upon its intended purpose, the tube connector may be directed to the rear, upwardly or laterally. In accordance with the invention different adapter attachments may be stocked the diameter and thread of the connector opening of which may be matched to given tubular connectors. Thus it is possible in an economically advantageous manner to manufacture and stock but a single model of the liquid processing device.
