COMPLETE SPECIFICATION
Air or other Gas Coolers We, SERCK RADIATORS LIMITED, of Warwick Road,
Greet, in the City of Birmingham, 11, a British Company, do hereby
declare the invention, for which we pray that a patent may be granted
to us, and the method by which it is to be performed, to be
particularly described - in and by the following statement:-
This invention relates to water-cooled air or other gas coolers used
in conjunction with compressors for cooling the air or other gas after
compression or between compression stages.
- A conventional form of such a cooler (hereinafter referred to as a
cooler of the kind is specified) comprises a casing having an inlet at
one end and an outlet at its opposite end, and in which is contained
an assembly of tubes arranged parallel with each other, the compressed
air or other gas being caused to flow over the tubes, and the cooling
water being caused to flow through the tubes. Within the casing and
between the inlet and outlet are arranged transverse baffle plates so
disposed that the air while flowing through the casing from the inlet
to the outlet, is caused to travel along a zig-zag path. Also it is
usual to combine with each tube along its whole length a helically
coiled metal strip, or a number of thin metal discs, to provide
secondary heat conducting surfaces.
A disadvantage of a cooler of the kind above specified, is that oil or
other foreign matter carried in suspension in the air is liable to
2. accumulate in and block the spaces between those secondary heat
conducting surfaces which occupy a position adjacent to the casing
inlet, and periodic removal of this accumulation is a troublesome
operation.
The object of the present invention is to enable the above mentioned
disadvantage to be obviated in a simple manner, without material
detriment to the efficiency of the cooler.
A cooler of the kind specified, and in accordance with the invention,
consists in part of tubes on each of which the secondary heat
conducting surfaces are provided on that portion only of the length of
the tube which lies between the end [Price 3s. 6d.] 780,082 32510/54.
of the casing adjacent to the outlet and the baffle adjacent to the
inlet.
In one form, an air cooler in accordance with the invention and as
illustrated by the accompanying drawing, comprises a casing a of
cylindrical or other form having a lateral air inlet b at one end and
a like outlet c at the other end. Within the casing is contained an
assembly of tubes d arranged parallel with each other, the ends of the
tubes terminating in end plates e which occupy and close the ends of
the casing.
Also within the casing is contained an arrangement of transverse
baffles f through which the tubes are inserted, the baffles being
disposed parallel with each other at a convenient distance apart, and
the form of the baffles being such that they cause the air to flow
over the tubes along a zig-zag path. One of the baffles is situated
adjacent to the inlet and at a convenient distance from the adjacent
end plate carrying one end of the tubes. Each tube is provided with a
helically-coiled fin, or a plurality of thin discs g serving as the
secondary heat conducting surfaces. The fins or discs extend along
only that part of each tube which lies between the said baffle and the
end of the casing adjacent to the outlet.
The casing is provided with end covers serving as headers I, i for
conveying the cooling water through the tubes, the header h being
provided with an inlet and an outlet, and being divided internally by
a partition, so that the incoming water is caused to flow through some
of the tubes to the other header i, and to return from the latter
along the other tubes.
It will be understood from the foregoing that the parts of the tubes d
adjacent to the inlet are plain. Consequently the usual tendency for
oil or other foreign matter carried by the air to accumulate on these
parts of the tubes is reduced and any accumulation which occurs can
readily be removed by periodic cleaning.
In the foregoing descriptionwe havereferred to "air," but we desire it
to be understood that this term is intended to include both
3. atmospheric air and any other gas.
