BACKGROUND OF THE INVENTION
Field of the Invention.
The present invention relates to a split and wall having
type air conditioner, and more particularly, the present
invention relates to a heat exchanger of a split and wall
ranging type air conditioner, which includes an upright
cooling fin section, a first inclined cooling fin section and
a second inclineoi cooling fin seoticn, and in which the second
inclined from a plane c: the first inclined cooling fin
section and extends downward from the upper end of the first
inclmec. cooling fin section write an air flow preventing moid
is intervened therebetween., to thereby reduce the volume and
size of an air conditioner body in which the heat exchanger is
mounted.
Description of the Prior Art
Generally, an air conditioner performs a cooling function
based on a phenomenon that a liquid absorbs neat when it
evaporates. The air conditioner may be designed to include a
oehumidifier and/or an air filter for removing moisture and/or
dust contained in an air.
. Referring tc FIG. 1, there is shown a c:iaf:ram for
illustrating principles of a cooling circuit: of an air
conditioner. When a refrigerant enters an expansion viivs; a?
a liquid under nigh pressure and passes through a metering
orifice within the expansion valve, the refrigerant is forced
through the small orifice and sprayed out into a heat
exchanger. Therefore, as the pressure of the refrigerant is
lowered, tie refrigerant is evaporated while it abscros heat
through pipes of the heat exchanger, by which a physical state
of the refrigerant is clanged from a liquid tc a vagir. he
this time, by directing warm air toward tne pipes . f tnt- neat
exchanger via a Oliver, the temperature of the ;¦ ::r. :. i : is
lowered to be capable of cooling a room.
When the refrigerant passes through a compress:.:, its
pressure is increased. As the heat-laden, high pressure
refrigerant vapor enters a condenser, it is crimen cy an
ambient air tc be condensed back to a liquid.
Accordingly, the refrigerant performs a cooling fi.net i an
as it is circulated in the cooling circuit while being tranced
in its phvsicai state from a liquid to a vapor ano cacx tt a
liquid again tc complete a cooling cycle.
On the ether hand, an air conditioner can be divided into
a tower type air conditioner and a wail hanging type air
conditioner. Further, the air conditioner consists of an
indoor unit including a heat exchanger and a blower, and an
outdoor unit including a compressor and a condenser.
The present invention relates to a wall hanging type air
conditioner and more particularly, to an indoor unit of a wall
hanging type air conditioner, which includes a heat exchanger
anc a blower.
In more detail, an air conditioner body, a grille body,
an insert grille, a drain assembly mounted to the grille body,
and an air flow direction adjustor for adjusting air flow
direction upward or downward, are disposed outside a wall
hanging type indoor unit constituting an air conditioner.
Further, a control cox, a neat exchanger, a fan motor, and a
blower connected to the fan rrttor to be driven thereby, arc-
disposed inside the wail hanging type indoor unit constituting
the air conditioner.
Accordingly, a refrigerant is flowed into an evaporator
from an outdoor unit, and the blower connected to the pan
motor is rotated to supply cccieo air into a room tnrough the
air flow direction adjuster.
The heat exchanger includes an upright cooling fin-
section having a plurality of cooling fins which extend
vertically, a first inclined cooling fin section connected to
an upper end of the upright cooling fin section such that it
is inclined from a plane of the upright cooling fin section
and extends upward from the upper end of the upright cooling
fin section, and a second inclined cooling fin section
connected to an upper end of the first inclined cooling fin
section such that it is inclined from a plane of the first
inclined cooling fin section and extends horizontally.
However, the heat exchanger of the prior art, constructed
as mentioned above, suffers from defects in that since tie
second inclined cooling fin section is connected to the first
inclined cooling fin section while extending horizontally, the
heat exchanger occupies excessive space. Kence, the volume of
the air conditioner body in which the heat exchanger is
mounted is increased, whereby space utilizing efficiency is
deteriorated.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been made in an
effort to solve the problems occurring in the prior art, arc
an object of the present invention is to provide a heat
exchanger of an air conditioner, in which a second inclined
cooling fin section is connected to an upper end of a first
inclined cooling fin section such that it is inclined from a
plane of the first inclined cooling fin section and extends
downward from the upper end of the first inclined cooling fin
section, to decrease space which is occupied by cooling fins
of the heat exchanger, whereby reducing the volume of an air
conditioner body in which the heat exchanger is mounted whiip* maintainipn a hp-it
exchanging property as it is.
In order to achieve the above object the present invention nrovides an
air conditioner comprising : an upright cooling fin section vertically installed in the
air conditioner ; a first inclined cooling fin section connected to an upper end of the
upright cooling fin section such that it is inclined from a plane of the upright cooling fin
section and extends upward from the upper end of the upright cooling fin section
wherein the connection between the first inclined cooling fin section and the upright
cooling fin section forms a body ; and a second inclined cooling fin section separately
fixed to an upper end of the first inclined cooling fin section such that it is inclined from
a piane of the first inclined cooling fin section and extends downward from the upper
end of the first inclined cooling fin section, to decrease space which is occupied by the
cooling fin sections.
BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS
The above objects, and other features and advantages of the present
invention will become more apparent after a reading of the following detailed
description when read in conjunction with the accompanying drawings in which
FIG. 1 is a diagram illustrating principles of a cooling circuit of a conventional
air conditioner,
FIG. 2 is a perspective view illustrating cooling fin sections
of an air conditioner in accordance with an
embodiment of the present invention, which are assembled with
one another; and
FIG. 3 is a side view of the cooling fin sections of FIG.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Reference will now be made in greater detail to a
preferred embodiment of the invention, an example of which is
illustrated in the accompanying drawings. Wherever possible,
the same reference numerals will be used throughout the
drawings and the description to refer to the same or like
parts.
Referring to FIGs . 2 and 3, an air conditioner in
accordance with an embodiment of the present invention
includes a heat exchanger 10 which has a cooling fin part 10a.
The cooling fin part 10a includes an upright cooling fin
section 12 having a plurality of cooling fins which extend
vertically, a first inclined cooling fin section 16 connected
to an uoper end of the upright cooling fin section 12 such
that it is inclined from a plane of the upright cooling fin
section 12 and extends upward from the upper end of the
upright ccoling fin section 12, and a second inclined cooling
fin section 20 connected to an upper end of the first inclined
ceding fin section 16 such that it is inclined from a plane
of the first; inclined cooling fin section 16 and extends
downward from the upper end of the first inclined cool ma fin
section 16.
A first air flow preventing moid 14 is intervened between
the upright cooling fin section 12 and the first inclined
cooling fin section 16, and a second air flow preventing mold
18 is intervened between the first and second inclined cooling
fin sections 16 and 20.
Here, the drawing reference numeral 22 represents an
inlet tube through which a liquid refrigerant under high
pressure is supplied into the heat exchanger 10, and tne
drawing reference numeral 2 4 represents an outlet tube through
which the liquid refrigerant under low pressure is discharged
cut of tne neat exchanger 10.
Due tc the fact that the first inclined cooling fin
section 16 and the second inclined cooling fin section 20 are
sicpingly connected to the upright cooling fin station 12 and
the first inclined cooling fin section 16, respectively, while
air flo^ preventing molds 14 and 18 are intervened
therebetween, respectively, an area which is occupied by the
heat exchanger 10, that is, an area which is occupied by an
entire indoor unit of the air conditioner, is reduced.
At this time, although the second inclined cooling fin
section 20 is siopingly connected to the first inclined
cooling fin section 16 such that it extends downward from the
upper end cf the first inclined cooling fin section 16,
because space through which room air flows is wide enough,
performance of the air conditioner is not deteriorated.
In other words, since only an angle over whic:. the first
and second inclined cooling fin sections 16 and 20 are
combined with each other is changed while the construction of
respective cooling fin sections 12, 16 and 20 is maintained as
it is, an area through which the room air flows is not
changed. Therefore, an amount of air flowing through the
cooling fin part 10a is also not changed.
Accordingly, it is possible to maintain tne a meant of
cooling air as it is, and by reducing the volume of an air
conditioner boay, transportation and installation of the air
conditioner can be conveniently and easily carried out.
As described above, according to the present invention,
advantages are provided in that since a second cooling fin
section is connected to an upper end of a first inclined
cooling fin section such that it is inclined from a plane of
the first inclined cooling fin section and extends downward
from the upper end of the first inclined cooling fin section
while an air flow preventing mold is intervened between the
first and second inclined cooling fin sections, the volume and
size of an air conditioner body in which the heat exchanger is
mounted, are reduced.
In the drawings and specification, there have been
disclosed typical preferred embodiments of the invention and,
although specific terms are employed, they are used in a
generic and descriptive sense only and not for purposes of
limitation, the scope of the invention- being set forth in the
following claims.
