This invention relates to brine tanks and more
particularly to heat exchange tanks for use in
connection with household refrigerating appara
tus of either the absorption or compression types.
An object of the invention is to construct a
brine tank of great strength fabricated from
sheet metal stampings.
A further object of the present invention is to
construct a sheet metal brine tank which will

evaporator tubes of therefrigerating ‘apparatus
and which may be readily installed or removed as
a unit from the evaporator tubes.
A still further object is to construct a brine
15 tank unit made up of a liner and two identical
sheet metal sides which are easily ?tted to and
welded around the liner to form a complete
only strengthens the unit but also gives a large
air cooling area to the tank. The front and rear
edges of the sections 6 and ‘I are sloped inwardly
at 9 and I0 and welded to the outer edges 5' of
the liner l.
The flared top and bottom edges II and I2 of
the sections 6 and 'l are welded together to form
a complete brine tank having a large open inner
space for the reception of the ice trays.
A threaded nipple l3, forming ?lling nozzle, for 10
interior space of the brine tank is fastened in a
sloping beveled front edge 9 of one of the main
side sections, while offset hangers M are welded
to the rear sloping sections Ill to assist in sup
porting the tank unit in the refrigerating box. 16‘

Referring more speci?cally to the drawings:
Numeral l illustrates a rectangular sheet metal
casing formed of a single piece of bent metal
welded at 2 along its upper central abutting edges.
The liner l is provided with oppositely disposed
pairs of vertically spaced pressed-in sections 3,
leaving longitudinal grooves 4 between each pair
of pressed-in sections 3. It will be observed from
Figure 4 of the drawings that the outer ends of
the pressed-in sections 3 are beveled as indicated
by numeral 5 and terminate in a ?at edge 5'.
45 Thus it will be seen that the liner 1 constitutes
the inner surface of the brine tank which has a
large unobstructed central area.
The outer spaced side walls and top and bot
tom of the tank are made from two identical U
two halves ?tted around the liner are identical
and prepared from the same dies so that there are
no rights or lefts but may be used interchange 35
ably. In assembly, the two outer stampings are
?tted over the liner and welded at their top and
bottom meeting lines and also to the outer edges
of the liner.
The corrugated top, bottom and sides give 40
strength to the unit and also provide channels
for accelerating the circulation of chilled air
around the tank and consequently through the
food compartment of the refrigerator.
As before stated, the present invention is suit—
able for use with all types of household refrig
eration apparatus and functions equally well with
an absorption cycle system as with a motor
compresslon out?t. In either type, the evapora
one-half of the top and bottom of the tank and,
tion tubes or coils are frictionally ?tted into the 50
grooves formed in the side walls of the liner and
snugly held thereby to e?ect an e?icient heat ex

shaped sheet metal stampings 6 and 1. Each
of these stampings consists of a side wall and
55 numeral 8. This corrugated‘ construction not
change to the liquid in the tank and to the ice.
While not shown, it will be understood by those 65
skilled in the art that the lique?ed refrigerant in
the system is ?owed through the tubes i‘! to chill
the brine or other heat exchange ?uid retained
in the hollow Walled tank. The tubes iii are con
nected to the evaporator or liquid gas receiver
and may be of any suitable construction provided
they are in solid contact with the horizontal
grooves ii to thus effect proper heat exchange
with the side walls 01 the liner.
What I claim is:
1. A brine tank including a holiow inner liner
having pairs 01’ vertically spaced longitudinal
grooves integrally formed in the side walls there»
of, adapted to frictionally engage and be sup
15 ported on the evaporator tubes of a refrigerat
ing system, and a. spaced casing surrounding
the top, bottom and sides or" said liner ffornnng
a ?uid tight container.
2. A cooling unit for refrigerating apparatus
including a hollow rectangular, ?uid-tight, dou
ble walled casing open at both ends thereof, a
plurality of pairs of horizontal, vertically spaced
grooves formed in the inner side walls of the
said casing and extending from end to end
25 thereof, the said grooves being adapted to re»
tain a plurality of pipes in. circuit with the
evaporator of the refrigerator system to there“
by support the said cooling unit.
3. A brine tank for refrigerators consisting of
30 a hollow rectangular inner casing having
pressed-out horizontal grooves in its inner side
walls for the reception of conduits carrying iiq~
uid refrigerant, the said inner casing comprising
a single sheet of bent metal, and a spaced outer
casing enclosing said inner _ casing comprising
two identical hollow sheet metal stampinge oi’
substantial U—shape fitted on either side or said
inner casing and welded thereto.
4. A brine tank for refrigerators including an
inner liner formed from a single sheet oi’ metal
bent to form a hollow rectangular casing with
its meeting edges welded together, integral, hor
izontal, parallel, spaced apart grooves i'ormed in 10
the opposite vertical side walls of said inner liner,
a spaced outer casing surrounding the four sides
of said inner liner and welded thereto adjacent '
the open ends of the said inner liner, the outer
casing being fabricated from two identical sheet
metal sections welded together at their abutting
5. A brine tank for household refrigerators
including an inner liner in the form of an open
ended sheet metal rectangle, and having grooves
formed in its inner walls for the reception of 20
refrigerating conduits, an outer casing surround
ing the said inner liner at the top, bottom~ and
two sides thereof, said outer casing comprising
two identical sheet metal sections of substantial 25
u shape both in con?guration and in cross sec-'
tion. each outer section of said casing forming
a side wall and one half of the top and the bot
tom. for said liner, the abutting edges of the
two sections of said casing being'welded to each 30
other and the outer edges thereof being welded
to the inner liner adjacent its open ends.
