2 Claims.
(Cl. 257-130)
This invention relates to cores for radiators
designed for motor vehicles, air conditioning sys
Figure 4 is an enlarged vertical section through
the sheathing plates of a unit, a portion being
tems, refrigeration systems, and, in fact, wher
broken away.
Figure 5 is an enlarged vertical transverse sec
ever the rapid transfer of thermal units is de
5 sired. It is more particularly an improvement
on the structure disclosed in the patent to Spery
and Spery, No. 1,301,984, issued on April 29, 1919.
An object of the present invention is to provide
a radiator core of the honeycomb type wherein
10 hexagonal air passages are arranged in vertical
columns.
It is an object of the invention to form the
radiator core of permanently assembled units,
each unit including a sheathing constituting the
15 sides, top and bottom of the unit while surround
ed by each sheathing are ?ller plates so shaped
as to cooperate with the sheathing and with each
other to form hexagonal air passages of uniform
area, there being connections between the super
20 posed passages in each unit through which air
can ?ow upwardly or downwardly from one pas
sage to another.
A still further object is to provide ?ller plates
having means whereby they will be extended
25 from front to rear and which can be joined by
solder or other suitable binder so distributed as
tion through portions of the ?ller plates of a
unit.
Figure 6 is an enlarged section on line €3-6,
Figure 2 taken through both the sheathing and
filler plates.
,
Figure 7 is an enlarged section on line l-l', 10
Figure 2, taken through both the sheathing and
?ller plates.
.
Referring to the figures by characters of ref
erence, I designates opposed sheathing plates.
the upper and lower edge portions of which are 15
bent to form flanges 2 which are extended toward
each other and joined by seams 3, thus to form a
continuous sheathing extending throughout the
height of the radiator core and throughout the
width of the radiator unit.

Each edge of each plate is crimped longitudi
nally to form a series of outwardly extended
semi-hexagonal o?sets 4 while between these
offsets are inwardly extended semi-hexagonal
offsets 5. The offset portions 4 and 5 do not 6X1
tend throughout the width of the plates from
front to rear but merely extend backwardly short
to offer the minimum resistance to the conduc
tion of thermal units from one plate to the other ' distances as shown particularly in Figures 2 and 3
and those portions of each plate between the in
of the unit.
wardly extended offsets 5 are pressed inwardly 30

A still further object is "to so shape the sheath
ings of the units that when the units are placed toward the opposed plate to form wedge-like
ribs 6.
together side by side the said sheathings will co
operate to formicolumns through which the ?uid
being cooled can flow freely.
35
With the foregoing and other objects in view
which will appear as the description proceeds,
the invention consists of certain novel details of
construction and combinations of parts herein
after more fully described and pointed out in the
40 claims, it being understood ‘that changes may be
made in the construction and arrangement of
parts without departing from the spirit of the
invention as claimed.
In the accompanying drawing the preferred
45 form of the invention has been shown.
In said drawing
Figure 1 is. a View partly in front elevation and
partly in transverse section of a portion of a
radiator core constructed in accordance with the
50 present invention.
Figure 2 is a side elevation of one of the units,
a portion of the sheathing being broken away to
show the ?ller plates of the unit.
Figure 3 is a section through a portion of the
55 radiator core taken on the line 3—3, Figure 1..
Between the outwardly extended offsets 4 the I
plates are likewise pressed inwardly toward each
other to form substantially ?at parallel faces ‘I 35
from which the ribs 6 diverge.
Interposed between the sheathing plates l ‘of
each unit are a pair of filler plates 8 and 9
respectively. These ?ller plates are duplicates
but are oppositely arranged relative to each other 49
so as to provide “rights” and “lefts” with corre
sponding portions directly opposed to each other.
Each plate is crimped along its front and back
edges to provide series of semi-hexagonal de
pressions, each series including outwardly offset 45
depressions l0 between which are formed in
wardly offset depressions H. That portion of
each plate between the outwardly offset depres
sions is pressed inwardly toward the opposed
plate to form a longitudinal channel indicated 50
at l2, this channel being proportioned to receive
one of the tapered ribs 6 of the-adjacent she-ath
ing plate. The walls of the channels can be
?attened out at spaced intervals as shown at
l3 so that when the channel portions l2 are 55
2

assembled with the ribs 6 therein, these ?attened
portions I3 will provide clearance for holding a
suitable binder such as solder, while those por
tions I3’ of the walls between the ?attened faces
I3 can contact directly with the sheathing plate,
thereby to provide perfect conduction of thermal
units from the ?ller plate at these points to the
adjacent portions of the sheathing plates.
Those portions of the ?ller plates between the
10 inwardly offset depressions II are pressed out
vertical passage the fluid to be cooled ?ows freely
from the top to the bottom of the unit.
It will be obvious in practice that air can
circulate freely longitudinally of the passages
I8 and I9. Water or other ?uid in the vertical
passages 2e will be quickly cooled through con
tact with the air cooled surfaces of the sheath
ing plates, it being understood that the plates
of which the radiator is formed are highly con
ductive of thermal units so that they will be 10
wardly toward the adjacent sheathing plates to
form longitudinal channels I4 and if desired

more efficient than would be the case should
As beforestated each radiator core is formed
with a number of units, all of the units being
the same and comprising connected opposed
sheathing plates and a pair of interposed ?ller
plates. The ?ller plates of each pair can be
there be a continuous unbroken layer of solder
held properly assembled while being handled by
forming small depressions I5 along one edge of
30 each ?ller plate and small nodes I‘! along the
corresponding edge portion of the opposed ?ller
plate so that when the two plates are properly
located relative to each other all of the nodes
will be seated in the opposed depressions. The
35 assembled ?ller plates are then positioned be
tween the sheathing plates and when properly
located the channeled portions I2 will provide
seats for the wedge-like ribs 6 of the filler plates.
The inwardly offset portions I I of the filler plates
40 will match the outwardly offset portions 4 of
the sheathing plates, thereby to provide air pas
sages I8 having hexagonal end portions.
The inwardly offset depressions II of the two
?ller plates will match each other thereby to
provide air passages I9 having hexagonal end
portions. The passages I 9 are interposed be
tween the inwardly extended portions of the pas
sages I8 and these passages communicate through
the clearances provided between the channeled
50 portions I2 of the filler plates. Thus the pas~
sages I9 are in constant communication verti
cally so that air can not only ?ow longitudinally
through said passages but also upwardly from
one passage I9 to another. If the channeled.
portions I2 are split or broken the air can also
flow laterally to and from the passages I8.
The meeting offset end portions of the sheath
ing plates and ?ller plates are joined by solder
so that each unit thus forms a rigid one-piece
60 structure.
The several completed units are assembled side
by side with the‘ outwardly offset portions ll of
the sheathing plates of each unit ?tting into
the inwardly offset portions 5 of the opposed
65 sheathing plate; Thus the units can be joined
by solder where these offset portions inter?t but
as the sheathing plates are all ?attened inwardly
betweerrthe outwardly offset portions 4 as indi
cated at ‘I it will be obvious that when the sheath
ing plates of the different units are inter?tted
and joined as described the ?attened portions ‘I
will cooperate to form a vertical passage 20 be
tween the units extending from the offset por
tions at one end of the unit to the offset portions
75 at the other end of the unit and through this ‘
between the meeting parts.
