This invention relates to new and useful improvements in cooling cabinets.
One object of the invention is to provide an
improved cooling cabinet which is so constructed
5 that a positive and unrestricted ?ow of cooling
medium is maintained around and in contact
with the objects to be cooled.
Figure 5 is an enlarged horizontal cross-sec
tional view taken on the line 5-5 of Figure 3.
In. the drawing, the numeral Ill designates an
elongate rectangular cabinet or housing, which
is, formed of an outer shell II and an inner shell 5
l2 spaced from each other and suitably con
nected together.’ The space between the walls ,
and bottoms of the shells is ?lled with an insu

Another object of the invention is to provide
an improved coolin'g cabinet having a chamber
for receiving objects to be cooled and an elongate
restricted passage communicating with the chain;

A ‘construction-designed to. carry out the-in‘
vention will be hereinafter described, together
with other features of the invention.
The invention will be more readily understood
from a reading of the following speci?cation and
central vertical partition I! extends longitudinal
ly of the chamber between the battle l8_and the
opposite end wall It thereby dividing the cham
ber‘into two parallel sections.
40
(A pInrality-oFIoi-aminous partitions 20 are
mounted in
relation within each section
of the chamber'C and extend transversely there- of. ' Each partition is formed'of a section of
by reference to the accompanying drawings,v in'
hardware cloth 2|, or other suitable foraminous. 45
which an example of the invention is shown, and
metallic frame 22. The partitions are preferably
removable, being adapted to ?t in channel mem
wherein:

Figure l is in isometric view, partly in eleva
material. having its edges con?ned within a
-
tion and partly in section, of a cabinet construct- ~ bers 23 provided on the walls of the chamber and
‘,0 ed in accordance with the invention,
Figure 2 is a plan view of the cabinet,‘
Figure 3 is an enlarged transverse vertical
sectional view taken on the line 3--3 of'?gure 2,
Figure 4 is a transverse vertical sectional view
;5 taken on the-line 4-—4 of- Figure 2, and _
the longitudinal partition i9, whereby they may 50
be readily and quickly inserted or removed to
divide each section of the chamber into compart
ments'.
Openings 24 are provided" in the end wall ii of
the casing whereby communication is established 55
2
2,109,714
between each section of the chamber C and the
passage E. Similar openings 25 are provided in
the baf?e l8 for establishing communication be
tween the sections of the chamber C and the
space between said baiiie and the end wall H of
the casing. The openings 24 and 25 are prefer
ably covered with hardware cloth or other
foraminous material. A circular opening 26 is
provided centrally of the end wall ll of the casing
10 and an annular ?ared collar 21 surrounds the
opening and extends into the chamber.
An impeller or fan 28 is mounted within the
opening 26 on a shaft 29 which extends outwardly
therefrom through a ?uid tight bushing 30 in
15 the end of the cabinet. A pulley 3| is mounted
on the outer end of the shaft and belts 32 con
nect the pulley with the drive shaft of’ a motor
33, whereby the impeller is driven by said motor.
The blades of the impeller are arranged to force
20 a cooling medium within the cabinet from the
passage F into the chamber C in the direction
of the arrows (Figure 2). It is noted that the
impeller is located in alinement with the longi
tudinal partition I! whereby a cooling medium,
25 such as brine, actuated by the impeller, is
directed equally into the sections of the cham
ber C. A cooling element 34 is mounted within
the elongate passage D and includes a coil formed
of a plurality of longitudinally disposed pipes 35
80 spaced vertically within said passage. The ends
of the coil extend outwardly through suitable
bushings in the end of the cabinet and are con
nected to a source of refrigerant (not shown).
Drains 38 are provided in the bottom of the
a
therebetween within each section of the chamber
C may be readily and quickly varied. Manifestly,
circulation of the cooling medium through the
‘compartments is unrestricted due to the fact that
the partitions are made of a foraminous mate
rial.
It is noted that the provision of the cooling coil
34, within the elongate passage D reduces the
amount of space usually occupied by such coils
to a minimum, thereby increasing the amount 10
of space within the cabinet available for use as a
cooling chamber. Also, such an arrangement
makes for a more compact structure, thereby re
ducing costs of materials and manufacture.
Due to the fact that the cooling medium en 15
gages the baf?e M, a heat transfer is made
possible whereby the interior of the chamber B
is cooled. Since no liquid cooling medium enters
this chamber, objects which cannot be immersed
in a liquid may be readily cooled therein.
-It is pointed out that due to the position of the
impeller 28 with relation to the longitudinal
partition l9 within the chamber C equal streams
of cooling medium are forced through each
section of the chamber, thereby insuring the 25
inmaintenance of an even temperature therein.
What I claim and desire to secure by Letters
Patent is:
1. A cooling cabinet including, a housing hav-_
ing a. chamber therein for receiving objects to be
cooled, a longitudinal partition within the cham
ber and dividing the same into sections, a cooling
element within the housing and outside the cham
ber, means at one end of the chamber for cir
compartments A and B whereby liquid in said culating a cooling medium through the sections
of the chamber and into contact with the cooling
compartments may be removed therefrom.
In use the large compartment A is filled with - element, said medium being constantly re-cycled
a liquid cooling medium, such as salt brine or ‘the through the chamber and over the element, and
like, and bottles, cans or other obi ectsto be cooled removable foraminous partitions within the sec
are placed within the compartments formed by tions of the chamber for forming a plurality of
the foraminous partitions 20 within the chamber compartments therein and permitting an unre
C. > The impeller, actuated by the motor 3!, stricted flow of cooling medium through said
forces the cooling medium equally through both
sections of the chamber C and outwardly through
45 the openings 2| in the end wall of the easing
into the passage E. The medium is then forced
from the passage E in the direction of the arrows
(Figure 2) into the elongate passage D having
. the cooling coil 34 mounted therein.
The brine
50 is cooled while traversing the passage D and is
directed therefrom into the passage F from which
it is moved by the impeller 28 through the open
ings 25 into the chamber C, whereupon the cycle
is repeated.
56
,
Such circulation of the cooling -medium, con
stantly re-cycling said medium through the cool
ing chamber C, the passage E, over the cooling
coil in the passage D, and leading through the
passage F to the chamber C, obviously serves to
60 maintain an even temperature within the cabinet.
In traversing the elongate narrow passage D,
the cooling medium is sustained in intimate rela
tion with the cooling ‘coil positioned therein, be
cause of the restricted passageway therethrough.
65 Due to such intimate relation and the length of
the passage it will be seen that the cooling effect
of the coil upon the medium is amplified and the
maintenance of an even temperature is facili
tated.
70
-
The provision of the partitions 20 makes it
I possible to divide the chamber C into a large
number of compartments for separating various
sizes or kinds of objects to be cooled from each
other. Since the partitions are removable it will
75 be seen that the size of the compartments formed
compartments.
' 2. A cooling cabinet including, a housing, a
casing forming a chamber within the housing for
receiving objects to be cooled, and being so dis
posed that an angular passage is formed between
the housing and chamber, said passage connect~
ing the ends of said chamber, one end wall of
the chamber being formed of foraminous mate
rial and the other end wall having a central
opening formed therein, a cooling element with
in the passage formed between the housing and
chamber, ‘and an impeller mounted within the
central opening in the end wall of the chamber
for circulating a cooling medium through the
compartment and into contact with the cooling
element in the passage, said medium being con
stantly re-cycled through said compartment and
over said element.
. 3. A cooling cabinet including, a housing, a cas
ing forming a chamber within the housing for
receiving objects to be cooled, and being so dis
posed that an angular passage is formed between
the housing and chamber, said passage connect
ing the ends of said chamber, one end wall of
the chamber being formed of foraminous mate
rial and the other end wall having a central
opening formed therein, a cooling element with
in the passage formed between the housing and
chamber, an impeller mounted within the cen
tral opening in the end wall of the chamber to:
circulating a cooling medium through the com
partment and into contact with the cooling ele
ment in the passage, said medium being con
3
\’ 2,109,714
stantly re-cycled through said compartment and
over said element, and foraminous partitions
within the chamber for forming .a plurality oi
‘compartments therein and permitting an unre
stricted ?ow of cooling medium through said‘
compartments.
4. A cooling cabinet including, a housing, a
casing forming a chamber within the housing for
receiving objects to be cooled, and being so dis
10 posed that an angular passage is formed be
tween the housingv and chamber, said passage
connecting the ends of said chamber, one end
