[0001] The present application claims priority of Korean Patent
Application Number 10-2014-0072419 filed on Jun. 13, 2014, the
entire contents of which application are incorporated herein for
all purposes by this reference.
BACKGROUND OF INVENTION
[0002] 1. Field of Invention
[0003] The present invention relates to a radiator in a vehicle.
More particularly, the present invention relates to a radiator in a
vehicle, in which positions of an inlet and an outlet of cooling
water to/from an engine are optimized to reduce flow resistance and
increase a flow rate thereof for improving a cooling
performance.
[0004] 2. Description of Related Art
[0005] In general, a vehicle runs as an combustion of mixed gas of
fuel and air in an engine cylinder compressed by a piston is
transmitted to driving wheels. An engine which obtains driving
force from the combustion is provided with a cooling unit, such as
a water jacket, for cooling down heat of the combustion, and a
radiator for cooling the cooling water circulated through the water
jacket, in turn.
[0006] In the radiator having above described function, there are,
depending on a cooling type, an air cooling type radiator and a
water cooling type radiator, or, depending on a configuration, a
cross-flow type radiator and a down-flow type radiator.
[0007] The air cooling type is a type cooled by external air and
used the most generally, starting from small engines, and the water
cooling type is a type used for large sized engines in which the
radiator is cooled with the cooling water provided separately.
[0008] The cross-flow type and the down-flow type are classified in
terms of a flow direction of the cooling water. A related art
radiator is provided with an inlet tank for introduction of the
cooling water thereto and an outlet tank for discharge of the
cooling water provided spaced from each other, and a stack of tubes
each connected between the inlet tank and the outlet tank for flow
of the cooling water through an inside of the tubes and the
external air through an outside of the tubes for cooling down the
cooling water.
[0009] In this case, the cross-flow type is a type in which the
inlet tank and the outlet tank are arranged on left and right sides
of the radiator and the tubes are stacked in a horizontal direction
for the cooling water to circulate in the horizontal direction for
being cooled down by the external air.
[0010] And, the down-flow type radiator is a type in which the
inlet tank and the outlet tank are arranged on an upper side and a
lower side of the radiator, and the tubes which connect the tanks
are stacked in a vertical direction for the cooling water to
circulate in the vertical direction for being cooled down by the
external air.
[0011] The radiator having above configuration is arranged in an
engine room of the vehicle to face a front of the vehicle for
making the cooling water to heat exchange with cold external air
introduced thereto during running of the vehicle.
[0012] However, the related art radiator has a problem in that, if
the cooling water discharged after cooling the engine has bubbles
dissolved therein, making the cooling water to flow in a state the
cooling water contains the bubbles which have a low heat transfer
coefficient, the bubbles occupy a certain volume in a cooling water
circulation passage, and make a heat exchange performance of the
cooling water poor to reduce cooling efficiency.
[0013] Moreover, since the reduced cooling efficiency of the
radiator may lead to supply the cooling water to the engine in a
state the cooling water is failed to be cooled to a required
temperature, making the cooling water to fail to cool down the
engine properly, an overall cooling performance of the vehicle may
become poor.
[0014] The information disclosed in this Background section is only
for enhancement of understanding of the general background of the
invention and should not be taken as an acknowledgement or any form
of suggestion that this information forms the prior art already
known to a person skilled in the art.

[0026] FIG. 1 is a block diagram of a radiator in a vehicle in
accordance with various embodiments of the present invention.
Referring to FIG. 1, the radiator 10 in a vehicle improves cooling
efficiency without capacity increase by optimizing positions of an
inlet 15 and an outlet 17 in the radiator 10 of cooling water from
an engine 1 to reduce flow resistance and connecting a filler neck
20 which in some embodiments is provided separately in combination
with the radiator 10 to devise an increased flow rate.
[0027] For this, as shown in FIG. 1, basically, the radiator 10 in
a vehicle includes an inlet header tank 11 to which the cooling
water is introduced, and an outlet header tank 13 from which the
cooling water is discharged, arranged spaced at a predetermined
distance from each other.
[0028] The radiator 10 also includes a heat exchange unit 18 having
a plurality of tubes T arranged at equal or substantially equal
distances connected between opposite insides of the inlet header
tank 11 and the outlet header tank 13 with heat dissipation fins P
provided between adjacent tubes T for making the cooling water
flowing through the tubes T to heat exchange with the external air
introduced between the adjacent tubes T during running of the
vehicle.
[0029] In the radiator 10, the inlet header tank 11 has an inlet 15
formed in or substantially in a center of a height of one side
thereof and the outlet header tank 13 has an outlet 17 formed in a
center of the height of one side thereof. In this case, the inlet
15 and the outlet 17 may be arranged on or substantially on the
same line that connects the centers of one sides of the inlet
header tank 11 and of the outlet header tank 13.
[0030] That is, the radiator 10 increases a flow rate of the
cooling water by forming the inlet 15 and the outlet 17 at or
substantially at the centers of the inlet header tank 11 and the
outlet header tank 13 at which a pressure drop in the inlet header
tank 11 and the outlet header tank 13 is favorable in view of the
flow rate, and arranging the inlet 15 and the outlet 17 on the same
line that has the shortest distance to position the inlet 15 and
the outlet 17 at the shortest distance.
[0031] In the meantime, in describing the radiator 10 in a vehicle
in accordance with various embodiments of the present invention,
though the present exemplary embodiment suggests arranging the
inlet 15 and the outlet 17 on the same line which connects the
centers of one sides of the inlet and outlet header tanks 11 and
13, the radiator 10 in a vehicle in accordance with various
embodiments of the present invention is not limited to this, but,
with reference to the inlet 15 formed in the inlet header tank 11,
the outlet 17 may be formed at the center of one side of the outlet
header tank 13 or at a position spaced downward a predetermined
distance from the center of one side of the outlet header tank
13.
[0032] That is, the outlet 17 may be formed at the center the same
with the inlet 15 or between the center and a position spaced
downward a predetermined distance from the center. This may be
applicably varied with the pressure drop of the radiator 10.
[0033] The radiator 10 includes a filler neck 20 connected to the
engine 1, connected to the inlet 15 with a main hose 21 for
introducing the cooling water from the engine 1 thereto, and
connected to a sub-hose 23 which is connected to the filler neck 20
separate from the main hose 27 and connected to one of the inlet
header tank 11 and the outlet header tank 13 in parallel with the
main hose 21.
[0034] In this case, referring to FIG. 1, the radiator 10 may have
a sub-hose 23 connected to a sub-inlet 19 spaced upward from the
inlet 15 and formed in the inlet header tank 11. That is, the main
hose 21 may have one end connected to a lower side of the filler
neck 20, and the other end connected to the inlet 15. Along with
this, the sub-hose 23 may have one end connected to one side of an
upper side of the filler neck 20, and the other end connected to
the sub-inlet 19.
[0035] In the meantime, in exemplary embodiment illustrated in FIG.
1, the filler neck 20 is provided separately from the inlet header
tank 11 to be positioned and connected between the engine 1 and the
inlet header tank 11 for flow of the cooling water.
[0036] The filler neck 20 may separate bubbles from the cooling
water introduced thereto from the engine 1, for introducing the
cooling water having the bubbles removed therefrom to the inlet 15
through the main hose 21 and a portion of the cooling water
containing the bubbles to the sub-inlet 19 through the sub-hose
23.
[0037] In the meantime, the filler neck 20 is connected to a
reserve tank 3 for separating the bubbles from the cooling water
introduced thereto from the engine 1 thus, and discharging the
bubbles separated thus in the filter neck 20 to the reserve tank
3.
[0038] In this case, the filler neck 20 has an inlet port 25 formed
on one side of an upper side thereof for introduction of the
cooling water thereto from the engine 1, and an outlet port 27
formed on a lower side thereof having the main hose 21 connected
thereto.
[0039] And, the filler neck 20 may have a sub-outlet port 28 formed
on the other side of the upper side opposite to the inlet portion
25 to have the sub-hose 23 connected thereto, and a bubble
discharge port 29 on one side of the upper side having a cap C
mounted thereto connected to the reserve tank 3.
[0040] That is, the cooling water discharged from the engine 1 is
introduced to the filler neck 20 through the inlet port 25, and has
the bubbles separated therefrom, and the cooling water having the
bubbles separated therefrom is discharged through the outlet port
27 and introduced to the inlet 15 of the inlet header tank 11
connected thereto with the main hose 21.
[0041] And, a portion of the cooling water having the bubbles not
completely separated therefrom is discharged through the sub-outlet
port 28 and introduced to the sub-inlet 19 formed on the upper side
of the inlet 15 in the inlet header tank 11.
[0042] The radiator 10 can reduce the flow resistance of the
cooling water flowing therein as the inlet 15 and the outlet 17 are
arranged on or substantially on the same line with the centers of
the inlet header tank 11 and the outlet header tank 13.
[0043] Moreover, the radiator 10 can increase an entire pass
through flow rate of the cooling water even if a total capacity or
a size thereof are not increased, by introducing the cooling water
having the bubbles separated therefrom not completely through the
sub-hose 23 altogether for increasing the flow rate of the cooling
water additionally by utilizing the reduction of the flow
resistance.
[0044] Along with this, the increased pass through flow rate of the
cooling water enables to reduce power consumption of the water
pump, to improve fuel consumption of the vehicle, and the cooling
efficiency and the cooling performance of the cooling water,
thereby enhancing the cooling performance of the engine 1, too.
[0045] In the meantime, FIG. 2 is a block diagram of a radiator in
a vehicle in accordance with various other embodiments of the
present invention. That is, referring to FIG. 2, basically, the
radiator 100 includes an inlet header tank 111 to which the cooling
water is introduced, and an outlet header tank 113 from which the
cooling water is discharged, arranged at a predetermined distance
from each other.
[0046] The radiator 100 also includes a heat exchange unit 118
having a plurality of tubes T arranged at equal or substantially
equal distances connected between opposite insides of the inlet
header tank 111 and the outlet header tank 113 with heat
dissipation fins P provided between adjacent tubes T for making the
cooling water flowing through the tubes T to heat exchange with the
external air introduced between the adjacent tubes T during running
of the vehicle.
[0047] In the radiator 100, the inlet header tank 111 has an inlet
115 formed in or substantially in a center of a height of one side
thereof and the outlet header tank 113 has an outlet 117 formed in
or substantially in a center of the height of one side thereof. In
this case, the inlet 115 and the outlet 117 may be arranged on or
substantially on the same line that connects the centers of one
sides of the inlet header tank 111 and the outlet header tank
113.
[0048] That is, the radiator 100 increases a flow rate of the
cooling water by forming the inlet 115 and the outlet 117 at the
centers of the inlet header tank 111 and the outlet header tank 113
at which a pressure drop in the inlet header tank 111 and the
outlet header tank 113 is favorable in view of the flow rate, and
arranging the inlet 115 and the outlet 117 on or substantially on
the same line that has the shortest distance to position the inlet
115 and the outlet 117 at the shortest distance.
[0049] In the meantime, like the exemplary embodiment illustrated
in FIG. 1, in describing the radiator 100 in a vehicle in
accordance with various other embodiments of the present invention,
though the exemplary embodiment illustrated in FIG. 2 suggests
arranging the inlet 115 and the outlet 117 on or substantially on
the same line which connects the centers of one sides of the inlet
and outlet header tanks 111 and 113, the radiator 100 in a vehicle
in accordance with various embodiments of the present invention is
not limited to this, but with reference to the inlet 115 formed in
the inlet header tank 111, the outlet 117 may be formed at the
center of one side of the outlet header tank 113 or at a position
spaced downward a predetermined distance from the center of one
side of the outlet header tank 113.
[0050] That is, the outlet 117 may be formed at the center the same
with the inlet 115 or between the center and a position spaced
downward a predetermined distance from the center. This may be
applicably varied with the pressure drop of the radiator 100.
[0051] The radiator 100 includes a filler neck 120 connected to the
engine 1, connected to the inlet 115 with a main hose 121 for
introducing the cooling water from the engine 1 thereto, and
connected to a sub-hose 123 which is connected to the filler neck
120 separate from the main hose 127 and connected to one of the
inlet header tank 111 and the outlet header tank 113.
[0052] Thus, the radiator 100 illustrated in FIG. 2 is similar to
or identical to the radiator 10 illustrated in FIG. 1 in view of
overall configurations except the position of a sub-inlet 119 to
which the sub-hose 123 is connected. That is, in the radiator 100
in a vehicle, the sub-hose 123 may be connected to the sub-inlet
119 formed at a position spaced upward from the outlet 117.
Therefore, the sub-hose 123 may have one end connected to one side
of an upper side of the filler neck 120, and the other end
connected to the sub-inlet 119.
[0053] Accordingly, in the radiator 100, the cooling water
discharged from the engine 1 is introduced to the filler neck 120
through the inlet port 125 and has the bubbles separated therefrom,
and the cooling water having the bubbles separated therefrom is
discharged through the outlet port 127 and introduced to the inlet
115 of the inlet header tank 111 connected with the main hose
121.
[0054] And, a portion of the cooling water having the bubbles not
completely separated therefrom is discharged through the sub-outlet
port 128 and introduced to the sub-inlet 119 formed on an upper
side of the outlet 117 in the outlet header tank 113.
[0055] That is, in the radiator 100, the cooling water containing
the bubbles is introduced to the sub-inlet 119 positioned on the
upper side of the outlet 117 of the outlet header tank 115 which
receives the cooling water to be discharged to the engine 1 for
introducing the cooling water containing the bubbles to the engine
1 through the outlet 117, thereby increasing a total pass through
flow rate.
[0056] Upon application of the radiator 10, 100 in a vehicle in
accordance with various embodiments of the present invention,
positions of the inlet 15, 115 and the outlet 17, 117 to/from which
the cooling water from the engine 1 is respectively in/out can be
optimized enabling to minimize the flow resistance, and, at the
same time with this, the filler neck 20, 120 which is provided
separately is connected to the radiator 10, 100 to devise an
increased flow rate of the cooling water, thereby permitting to
improve an overall cooling efficiency without increasing a capacity
of the radiator 10, 100.
[0057] Moreover, the reduced flow resistance of the cooling water
reduces power consumption of the water pump enabling to improve
vehicle fuel consumption, and, at the same time with this, the
overall flow rate increase of the cooling water can improve an
engine cooling performance. Along with this, the improvement of the
cooling efficiency and performance without increasing the capacity
of the radiator 10, 100 can improve utilization of the small engine
room and enables easy mounting of the radiator 10, 100 in the
engine room.
[0058] For convenience in explanation and accurate definition in
the appended claims, the terms "upper" or "lower", and etc. are
used to describe features of the exemplary embodiments with
reference to the positions of such features as displayed in the
figures.
[0059] The foregoing descriptions of specific exemplary embodiments
