Improved Method and Machinery or Apparatus for Cooling Liquids.
I, JOHN GWYNNE, of the Firm of J. & H. Gwynne, of the Hammersmith Iron
Works, Hammersmith, W., Engineer, do hereby declare the nature of the said
invention to be as follows:-
-
The object of my invention is to provide for the cooling of liquids in an efficient
manner within a moderate space. For this purpose according thereto liquid to
be cooled and air (or it might be other gaseous fluid) at a lower temperature than
the liquid are brought together in the form of jets or streams in such-wise that
there is an efficient intermingling so that the air abstracts heat from and leaves
the liquid.
According to one arrangement liquid to be cooled is projected in the form of
annularly-arranged series of jets directed towards (or approximately towards) a
common poi in an imaginary projection of the axis of a jet of air so that as it were
the jet of air is projected upward into and through a hollow skeleton cone of liquid
to be cooled, has a more or less spraying effect, abstracts heat from the liquid and
passes away into the atmosphere or otherwise the liquid being conducted or allowed
to flow to the required place for use.
A construction of apparatus according to my invention is as follows:-
On a common shaft which may be that of a quick-running engine of any suitable
type or an electric motor or may be a shaft driven by a belt or otherwise from
any convenient source there are mounted the rotary parts of a centrifugal pump
and of a blower. A valve or valves is or are provided for controlling the passages
leading to or from or both to and from the pump and blower; the pump is con-
nected to a hollow ring furnished with a series of nozzles inclined towards a common
point or approximately so; the blower is connected to an air nozzle or blast pipe
arranged concentrically within the ring so that air under pressure escaping from
the nozzle will flow in the manner already described into and through the skeleton
cone composed of jets of liquid projected through the nozzles towards a common
point as before described. Below the ring there is a receptacle (it may be dish-like)
for cooled liquid whence there is or may be a suitable pipe or passage for conveying
the cooled liquid to any required place for use. The said receptacle is open to the
atmosphere and above it there is a casing which may be of any convenient form
such as cylindrical for the greater part of its length and of truncated conical form
at the upper part where it is covered but has a lateral outlet opening or openings
for the escape of air; the open lower part of this casing is so arranged in relation
to the ring that by the action of the jets there may be induced a flow of air from
the external atmosphere upward through the casing to assist in acting upon and
cooling the liquid.
Although the arrangement just described may in some cases be found a con-
venient one it will be evident that apparatus to operate on the principle of my
invention as above set forth might be constructed in various other forms.
My invention may be employed in the cooling of liquids for various purposes

condensers for cooling for re-use water that has been used for condensing steam.

Improved Method and Machinery or Apparatus for Cooling Liquids.
I, JOHN GWYNNE, of the Firm of J. & H. Gwynne, of the Hammersmith Iron
Works, Hammersmith, in the County of Middlesex, Engineer, do hereby declare
the nature of this invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement:-
The object of my invention is to provide for the cooling of liquids in an efficient
manner within a moderate space. For this purpose according thereto liquid to
be cooled and air (or it might be other gaseous fluid) at a lower temperature than
the liquid are brought together in the form of jets or streams in such-wise that
there is an efficient intermingling so that the air abstracts heat from and leaves
the liquid.
According to one arrangement-liquid to be cooled is projected in the form of
annularly-arranged series of jets directed towards (or approximately towards) a
common point in an imaginary projection of the axis of a jet of air, so that, as it were,
the jet of air is projected upward into and through a hollow skeleton cone of liquid
to be cooled, has a more or less spraying effect, abstracts heat from the liquid and
passes away into the atmosphere or otherwise, the liquid being conducted or allowed
to flow to the required place for use.
The accompanying drawings illustrate a construction of apparatus according
to my invention, Fig. 1 being a sectional elevation and Fig. 2 à horizontal section
on the line a-b.
On the crank shaft 1 of a quick running steam engine 2 which may be of any
suitable type there are mounted the rotary parts of a centrifugal pump 3 and of a
blower 4. The pump 3 is conected by a pipe 5 to a hollow ring 6 furnished with a
series of nozzles 7 inclined towards a common point or approximately so. A
valve 5ª is provided for controlling the passage leading from the pump; if desired,
the inlet pipe 3ª of the pump may also be provided with a valve. The blower 4 is
connected by a pipe 8, which may be controlled by a valve, to an air nozzle or blast
pipe 8 arranged concentrically within the ring 6, so that air under pressure
escaping from the nozzle or pipe 8 will flow in the manner already. described into
and through the skeleton cone composed of jets of liquid projected through the
nozzles towards a common point as before described. Below the ring there is a
receptacle 9 (it may be dish-like, as shown) for cooled liquid, whence there is or
may be a pipe 10, or, it may be, a passage, for conveying the cooled liquid to any
required place for use. The receptacle 9 is open to the atmosphere and above it
there is a casing 11 which may be of any convenient form, such as cylindrical for
the greater part of its length and of truncated conical form at the upper part,
where it is covered by a hood 11ª but has a lateral outlet opening or openings 11b for
the escape of air; the open lower part of this casing is so arranged in relation
to the ring 6 that by the action of the jets or streams of liquid and air there may
be induced a flow of air from the external atmosphere upward through the. casing
to assist in acting upon and cooling the liquid.
The shaft 1 that is common to the pump 3 and blower 4, instead of being the

page_text: crankshaft of a steam engine, may be that of a gas engine, the shaft of an electric
motor, or may be a shaft driven by a belt or otherwise from any convenient source.
Although the arrangement just described may in some cases be found a con-
venient one it will be evident that apparatus to operate on the principle of my
invention as above set forth might be constructed in various other forms.
My invention may be employed in the cooling of liquids for various purposes and
will be found particularly suitable for use in connection with the steam-engine
condensers for cooling for re-use water that has been used for condensing steam.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is:-
1. An improved method of cooling liquids wherein the liquid to be cooled and
air or other gaseous fluid at a lower temperature than the said liquid are brought
together in the form of intermingling jets or streams, the air abstracting heat
from the liquid and passing away substantially as described.
2. The method of cooling liquid hereinabove described wherein a jet of air is
projected upward and concentrically through a hollow skeleton cone of the liquid
to be cooled.
3. Apparatus for cooling liquids comprising a series of liquid discharging nozzles,
an air nozzle or blast pipe, an open ended casing surrounding the mingled jets of
liquid and air issuing from the nozzles, and a receptacle for cooled liquid, sub-
stantially as described.
4. Apparatus such as referred to in Claim 3 for cooling liquids constructed,
arranged and operating substantially as described with reference to and shown in
the accompanying drawings.
5. The combination with apparatus such as referred to in Claim 3 of a suitably
driven shaft, a centrifugal pump and a blower, the rotary parts of both of which
are mounted on the said shaft and the outlets from which are respectively connected
with the liquid discharging nozzles and with the air nozzle or blast pipe substan-
tially in the manner described with reference to and shown in the accompanying
drawings.
