Abstract
A receiver dryer mounting bracket (38) for a condenser system (20) includes a body (76) and an arm (78) coupled to and extending from the body (76). The body (76) has an opening (90) and seat sections (92, 94) positioned at opposing ends of a length of the opening (90). Flanges (71, 73) on inlet and outlet pipes (34, 36) of the condenser system (20) are seated in the seat sections (92, 94). An arcuate crimp section (102) of the body (76) is compressed to secure the inlet and outlet pipes (34, 36) in respective ones of the seat sections (92, 94) to form a pipe assembly (30). The pipe assembly (30) is coupled to a header (26) of the condenser system (20) prior to furnace brazing, and a receiver dryer (32) is subsequently mounted to the bracket (38).
Description
TECHNICAL FIELD OF THE INVENTION
The present invention relates to the field of air conditioning systems. More specifically, the present invention relates to a bracket for a receiver dryer of a sub-cooled condenser system.
BACKGROUND OF THE INVENTION
In a conventional vapor compression system, vapor refrigerant is compressed in the compressor, where its temperature is raised above the temperature of the cooling medium used at the condenser. A mixture of vapor and liquid refrigerant then enters the condenser where heat is extracted, and the refrigerant changes to a liquid. The liquid refrigerant then enters the thermal expansion valve, which controls the quantity of liquid refrigerant passing to the evaporator coils. Finally, the liquid refrigerant enters the evaporator and evaporates. Heat from the ambient atmosphere, for example, in a vehicle passenger compartment, is rejected to the refrigerant in the evaporator where it is absorbed as the latent heat of vaporization as the refrigerant evaporates. The now vaporized refrigerant is then directed to the compressor to be recycled through the system.
Some vapor compression systems include a receiver dryer which is intended to perform some or all of the following functions: filtration and/or dehydration of the refrigerant, compensation for variations in its volume, and separation of the vapor and liquid phases of the refrigerant. Typically, an inlet pipe is coupled between an upstream section of the condenser and an inlet port of the receiver for carrying the vapor and liquid phases of the refrigerant to the receiver dryer. An outlet pipe is coupled between an outlet port of the receiver and a downstream section of the condenser header for returning the liquid phase of the refrigerant to the downstream section. Interposing the receiver dryer between upstream and downstream sections of the condenser ensures the fluid in the downstream section circulates only in the liquid state. The downstream section, or sub-cooler section, of the condenser sub-cools the liquid refrigerant to a point below the temperature at which the liquid changes to a gas. The sub-cooled liquid phase refrigerant quality is low and its enthalpy is also low which increases the evaporator's ability to absorb heat as the refrigerant evaporates, thus improving the efficiency of the vapor compression system.
Condenser systems used in vehicle air conditioning systems are typically manufactured by first assembling brazing clad condenser components together, then passing the assembled components through a brazing furnace to braze, or fuse, the components together. Typically, one or more brackets are used to mount the receiver dryer, inlet pipe, and outlet pipe to a header of the condenser. The bracket or brackets may be first bolted or tack welded to the header prior to the brazing process. Bolting and tack welding prior to brazing is typically performed manually, thus resulting in undesirable labor costs for the manufacturing process.
In addition, some mounting brackets are assembled using a number of discrete components. An undesirably high number of discrete components increases the likelihood that the condenser system may be misassembled, and increases the potential for damaging the inlet and outlet pipes coupled between the condenser and the receiver dryer. Other prior art designs utilize large connector blocks for mounting the receiver dryer to the condenser header. These large connector blocks have greater mass, thus making the brazing process more difficult.
When a receiver dryer is included in a condenser system, it is often desirable to service the receiver dryer one or more times during the useable life of the condenser by replacing, replenishing, or refurbishing the desiccant inside the receiver dryer. The prior art vapor refrigeration systems, having mounting brackets of multiple discrete components, increases the duration and complexity of service performed on the receiver dryer, again resulting in undesirable labor costs. Thus, what is needed is a receiver dryer mounting bracket that enables simple, secure, and convenient fixation of the receiver dryer to the header.
SUMMARY OF THE INVENTION
Accordingly, it is an advantage of the present invention that a receiver dryer mounting bracket for a condenser system is provided.
It is another advantage of the present invention that a receiver dryer mounting bracket is provided that facilitates pre-assembly of the inlet and outlet pipes with the mounting bracket prior to brazing.
Another advantage of the present invention is that the receiver dryer mounting bracket provides a secure mount for the receiver dryer and promotes the correct connection of the receiver dryer to the condenser.
Yet another advantage of the present invention is that a receiver dryer mounting bracket is provided that enables rapid and simple servicing of the receiver dryer.
The above and other advantages of the present invention are carried out in one form by a bracket for use in a condenser system. The condenser system has two spaced apart headers, a plurality of parallel tubes extending between the headers for passing refrigerant between the headers, and a receiver dryer. An inlet pipe is coupled to one of the headers and an inlet port of the receiver dryer. An outlet pipe is coupled to the one of the headers and an outlet port of the receiver dryer. The bracket retains the inlet and outlet pipes in fixed relation with the one of the headers. The bracket comprises a body including a first surface, a second surface, and a side spanning a width of the body from the first surface to the second surface. The body has an opening extending through the body configured for passage of the inlet and outlet pipes. The first surface has first and second seat sections at the opening, the first seat section being configured for retention of the inlet pipe, and the second seat section being configured for retention of the outlet pipe. An arm is coupled to and extends from the side of the body. The arm has a concave surface for mating engagement with the one of the header tubes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1
shows a side view of a condenser system
20
for a vapor compression system (not shown). In an exemplary embodiment, the vapor compression system may be a vehicle air conditioning system known to those skilled in the art for cooling the passenger compartment of a vehicle. Condenser system
20
includes a condenser, generally designated
22
, and a receiver portion, generally designated
24
. Condenser
20
includes a pair of tubular, parallel headers, generally designated as a first header
26
and a second header
27
. Parallel tubes
28
extend between first and second headers
26
and
27
, respectively, for passing refrigerant between first and second headers
26
and
27
. Receiver portion
24
includes a pipe assembly, generally designated
30
, and a receiver dryer
32
. Pipe assembly
30
includes an inlet pipe
34
, an outlet pipe
36
, and a mounting bracket
38
.
In an exemplary embodiment, condenser
22
is a three pass condenser. As such, first header
26
includes imperforate walls
40
and
42
extending through first header
26
. Similarly, second header
27
includes an imperforate wall
44
extending through second header
27
. First header
26
includes an inlet opening
46
for receiving a mixture of vapor and liquid phase refrigerant from a compressor (not shown) of the vehicle air conditioning system (not shown). Below imperforate wall
44
, second header
27
includes an outlet opening
48
for directing liquid phase refrigerant from condenser
22
toward the evaporator (not shown) of the vehicle air conditioning system.
Referring to
FIGS. 2-3
in connection with
FIG. 1
,
FIG. 2
shows a top view of pipe assembly
30
coupled to first header
26
of condenser system
20
.
FIG. 3
shows an exploded perspective view of receiver portion
24
of condenser system
20
. As shown, between imperforate walls
40
and
42
, first header
26
includes an outlet
50
to which a header attachment end
52
of inlet pipe
34
couples. An outlet end
54
of inlet pipe
34
couples to an inlet port
56
of receiver dryer
32
. An inlet end
58
of outlet pipe
36
couples to an outlet port
60
of receiver dryer
32
, and an header attachment end
62
of outlet pipe
36
couples to an inlet
64
of first header
26
below imperforate wall
42
.
In general, vapor and liquid phase refrigerant enters condenser system
20
at inlet
46
of first header
26
. The refrigerant may be distributed by first header
26
to tubes
28
that are above imperforate wall
40
, referred to generally as a first upstream section
66
, to flow to second header
27
. Once the refrigerant enters second header
27
, it is distributed to tubes
28
that are above imperforate walls
42
and
44
, and below imperforate wall
40
, referred to generally as a second upstream section
68
, to flow to first header
26
. At first header
26
, the vapor and liquid phase refrigerant is routed to receiver dryer
32
via inlet pipe
34
.
Receiver dryer
32
may include a desiccant (not shown). The desiccant tends to absorb any water that is mixed with the refrigerant. Receiver dryer
32
further serves to separate the liquid phase refrigerant from the vapor phase refrigerant. After the liquid phase refrigerant and the vapor phase refrigerant are separated within receiver dryer
32
, liquid refrigerant is subsequently routed to tubes
28
below imperforate walls
42
and
44
, referred to generally as a downstream section
70
, via outlet pipe
36
.
Downstream section
70
, known as a sub-cooler section, of condenser system
20
sub-cools the liquid refrigerant to a point below the temperature at which the liquid changes to a gas. The sub-cooled liquid phase refrigerant increases the ability of the evaporator (not shown) of the vehicle air conditioning system to absorb heat as the refrigerant evaporates, thus improving the efficiency of the system. Following sub-cooling in downstream section
70
, the liquid refrigerant passes to second header
27
below imperforate wall
44
and exits from outlet opening
48
for eventual receipt at the evaporator (not shown) of the vehicle air conditioning system (not shown).
FIG. 3
further shows bracket
38
interposed between receiver dryer
32
and inlet and outlet pipes
34
and
36
, respectively. An O-ring
72
is positioned between outlet end
54
of inlet pipe
34
and bracket
38
. Similarly, another O-ring
72
is positioned between and inlet end
58
of outlet pipe
36
and bracket
38
. In addition, inlet pipe
34
includes a first flange
71
extending radially from outlet end
54
, and outlet pipe
36
includes a second flange
73
extending radially from inlet end
58
. Stop beads
75
extend radially from header attachment end
52
of inlet pipe
34
and from header attachment end
62
of outlet pipe
36
. A fastener
74
is directed through bracket
38
to enable the connection of receiver dryer
32
to bracket
38
.
As will be described in greater detail below, bracket
38
advantageously facilitates the pre-assembly of pipe assembly
30
prior to furnace brazing condenser system
20
. In particular bracket
38
retains inlet and outlet pipes
34
and
36
, respectively, in fixed relation with first header
26
without the need for additional fixtures. Following the brazing process, receiver dryer
32
is simply bolted to bracket
38
using fastener
72
.
Condenser system
20
is described as being a three pass condenser having an integral sub-cooling section for simplicity of illustration. However, the invention does not require that the condenser system be a three pass condenser. Rather, the number of passes will vary as dictated by the requirements of a particular system. Nor does the invention require that the condenser system be used solely in vehicle air conditioning systems. Rather, the present invention may be implemented in a number of vapor compression systems that employ a receiver dryer unit known to those skilled in the art.
Referring to
FIGS. 4-6
,
FIG. 4
shows a front view of receiver dryer mounting bracket
38
in accordance with a preferred embodiment of the present invention.
FIG. 5
shows a section view of the mounting bracket
38
taken along section line
5
—
5
of FIG.
4
.
FIG. 6
shows a perspective view of mounting bracket
38
.
Receiver dryer mounting bracket
38
includes a body
76
and an arm
78
coupled to and extending from body
76
. More specifically, body
76
includes a first surface
80
, a second surface
82
, and a side
84
spanning a first width
86
of body
76
from first surface
80
to second surface
82
. Body
76
and arm
78
of bracket
38
are fabricated as a single contiguous unit by milling, extrusion, or other manufacturing methods known to those skilled in the art. Arm
78
extends from side
84
of body
76
and includes a concave surface
88
for mating engagement with first header
26
(FIG.
2
).
An opening
90
extends through body
76
. Opening
90
is generally oblong in shape. A first seat section
92
and a second seat section
94
are positioned at opposing ends of a length
96
of opening
90
. Body
76
at each of first and second seat sections
92
and
94
exhibits a second width
98
. Second width
98
is less than first width
86
such that a side wall
100
is formed at each of first and second seat sections
92
and
94
, respectively.
Body
76
further includes an arcuate crimp section
102
extending from side
84
of body
76
. Arcuate crimp section
102
is approximately aligned with a mid-point
104
of length
96
of oblong opening
90
. Thus, arcuate crimp section
102
causes a mid-section span
106
of oblong opening
90
to be wider than an end-section span
108
of oblong opening
90
at each of first and second seat sections
92
and
94
, respectively. Body
76
also has an attachment hole
110
for passage of fastener
74
(
FIG. 3
) employed to couple receiver dryer
32
(
FIG. 3
) to bracket
38
.
FIG. 7
shows a perspective view of mounting bracket
38
with inlet and outlet pipes
34
and
36
positioned therein.
FIG. 8
shows a perspective view of mounting bracket
38
with arcuate crimp section
102
of bracket
38
compressed. A method of securing receiver dryer
32
(
FIG. 1
) to condenser
22
(
FIG. 1
) entails directing inlet pipe
34
through mid-section span
106
of oblong opening
90
, and moving inlet pipe
34
laterally to seat first flange
71
of inlet pipe
34
in first seat section
92
. Similarly, outlet pipe
36
is directed through mid-section span
106
and moved laterally to seat second flange
73
of outlet pipe
36
in second seat section
94
.
A gap
112
at each of first and second seat sections
92
and
94
is sized to accommodate the outer diameter of each of inlet and outlet pipes
34
and
36
, respectively, in order to move inlet and outlet pipes
34
and
36
into first and second seat sections
92
and
94
. In addition, first and second seat sections
92
and
94
are configured to enable each of first and second flanges
71
and
73
to reside within respective ones of first and second seat sections
92
and
94
, surrounded in part by side wall
100
(FIG.
5
).
Once first and second flanges
71
and
73
of inlet and outlet pipes
34
and
36
are seated in respective ones of first and second seat sections
92
and
94
, respectively, arcuate crimp section
102
is compressed to secure inlet and outlet pipes
34
and
36
in first and second seat sections
92
and
94
(as shown in FIG.
8
). Once arcuate crimp section
102
is compressed, gap
112
decreases so that inlet and outlet pipes
34
and
36
are prevented from moving out of first and second seat sections
92
and
94
. Thus, pipe assembly
30
(
FIG. 2
) is formed.
Following the fabrication of pipe assembly
30
, header attachment end
52
(
FIG. 2
) of inlet pipe
34
is positioned in outlet
50
(
FIG. 2
) of first header
26
until its stop bead
75
(
FIG. 3
) touches first header
26
. Concurrently, header attachment end
62
of outlet pipe
36
is positioned in inlet
64
(
FIG. 2
) of first header
26
until its stop bead
75
touches first header
26
.
The retention of first and second flanges
71
and
73
in first and second seat sections
92
and
94
, respectively, provides positive location and alignment of outlet end
54
(
FIG. 2
) of inlet pipe
34
and inlet end
58
of outlet pipe
36
with mating inlet and outlet ports
56
and
60
, respectively, (
FIG. 3
) on receiver dryer
32
, as well as with outlet
50
and inlet
64
on first header
26
. This positive location and alignment substantially promotes the correct connection of receiver portion
24
(
FIG. 1
) to condenser
22
.
Concave surface
88
(
FIG. 4
) of arm
78
is readily tack welded to first header
26
, shown in ghost form in
FIG. 8
, to attach pipe assembly
30
(
FIG. 2
) to condenser
22
(
FIG. 1
) Condenser
22
(
FIG. 1
) with attached pipe assembly
30
is subsequently passed through a brazing furnace (not shown) to braze, or fuse, pipe assembly
30
to first header
26
.
Following the brazing process, outlet end
54
(
FIG. 2
) of inlet pipe
34
is coupled to inlet port
56
(
FIG. 3
) of receiver dryer
32
(FIG.
3
), and inlet end
58
of outlet pipe
36
is coupled to outlet port
60
(
FIG. 3
) of receiver dryer
32
. Fastener
74
(
FIG. 3
) is then used to fasten receiver dryer
32
to body
76
of bracket
38
to secure receiver dryer
32
to condenser
22
.
Referring to
FIGS. 9-10
,
FIG. 9
shows a front view of a receiver dryer mounting bracket
114
in accordance with a second preferred embodiment of the present invention.
FIG. 10
shows a perspective view of receiver dryer mounting bracket
114
.
Receiver dryer mounting bracket
114
is similar to mounting bracket
38
. That is, mounting bracket
114
includes body
76
and arm
78
coupled to and extending from side
84
of body
76
. Mounting bracket
114
further includes oblong opening
90
, first and second seat sections
92
and
94
, respectively, at opposing ends of oblong opening
90
, arcuate crimp section
102
, and attachment hole
110
for accommodating fastener
74
(FIG.
3
).
An inner edge
116
of each of first and second seat sections
92
and
94
, respectively, delineates a portion of oblong opening
90
. Body
76
of mounting bracket
114
has first bend relief slots
118
and second bend relief slots
120
extending through body
76
and radiating outwardly from inner edge
116
. First bend relief slots
118
of first seat section
92
, located proximate arm
78
, are longer than second bend relief slots
120
. More specifically, the length, or depth, of first bend relief slots
118
are approximately one and a half to twice the length of second bend relief slots
120
.
The region of mounting bracket
114
about first seat section
92
has more mass than the region of mounting bracket
114
closest to second seat section
94
. This additional mass at first seat section
92
causes that region of mounting bracket
114
to be more rigid than the region of mounting bracket
114
proximate second seat section
94
. The length, i.e., depth, of first and second bend relief slots
118
and
120
has evolved through trial and error and establishes an optimal depth for substantially equivalent compression of oblong opening
90
at each of first and second seat sections
92
and
94
. The increased length of first bend relief slots
118
relative to second bend relief slots
120
allows first seat section
92
to compress, or close, at a ratio close to second seat section
94
.
When assembling pipe assembly
30
(
FIG. 2
) using mounting bracket
114
in place of mounting bracket
38
(FIG.
4
), as arcuate crimp section
102
is compressed, first and second bend relief slots
118
and
120
close, so that fingers
122
separating first and second bend relief slots
118
and
120
wrap around inlet and outlet pipes
34
and
36
. In the same motion, fingers
122
lightly embed into the outer wall of inlet and outlet pipes
34
and
36
to hold pipe assembly
30
(
FIG. 2
) together while still allowing inlet and outlet pipes
34
and
36
to move axially to absorb the various mating part tolerances as pipe assembly
30
is attached to first header
26
(FIG.
1
). Thus, the length of first and second bend relief slots
118
and
120
and the positioning of fingers
122
control the interference between mounting bracket
114
and inlet and outlet pipes
34
and
36
, while maintaining the orientation of pipes
34
and
36
.
Body
76
of receiver dryer mounting bracket
114
exhibits a width
123
, and arm
78
of bracket
114
exhibits an arm width
124
. Arm width
124
is less than width
123
such that a step
126
is formed between body
76
and arm
78
. Step
126
helps prevent flux from wicking (i.e., flowing or migrating) toward inlet and outlet pipes
34
and
36
, respectively, during the furnace brazing process. Thus, step
126
controls a post braze condition of inlet and outlet pipes
34
and
36
. Although step
126
is illustrated on mounting bracket
114
, it should be understood that mounting bracket
38
(
FIG. 4
) and mounting brackets described in connection with
FIGS. 11-12
may be adapted to include step
124
.
FIG. 11
shows a front view of a receiver dryer mounting bracket
128
in accordance with an alternative embodiment of the present invention. Receiver dryer mounting bracket
128
is similar to mounting brackets
38
(
FIG. 4
) and
114
(FIG.
9
). That is, mounting bracket
128
includes body
76
, arm
78
, oblong opening
90
extending through body
76
, first and second seat sections
92
and
94
, respectively, at opposing ends of oblong opening
90
, arcuate crimp section
102
, and attachment hole
110
for accommodating fastener
74
(FIG.
3
).
However, arm
78
of mounting bracket
128
further includes extension portions
130
, each of which extend symmetrically about a central axis with respect to the other of extension portions
130
. Extension portions
130
are configured to enable a snap fit of arm
78
about first header
26
, shown in ghost form, thereby eliminating the need for the tack weld, discussed above, prior to the furnace brazing process. The snap fit simplifies system assembly, thus reducing the labor costs associated with system assembly. Although extension portions
130

In summary, the present invention teaches of a receiver dryer mounting bracket for a condenser system. The retention of the inlet and outlet pipes in the mounting bracket provides positive location and alignment of the inlet and outlet pipes with the receiver dryer, as well as with the condenser header. This positive location and alignment promotes the correct connection of the receiver portion to the condenser header. In addition, the mounting bracket provides a self-fixturing subassembly using, at most, a single tack weld and no additional fixtures to secure the assembly to the condenser header prior to furnace brazing. Following brazing, the bracket provides a secure mount for the receiver dryer via a through-hole for a single fastener connection. The single fastener connection of the receiver dryer to the mounting bracket enables rapid and simple servicing of the receiver dryer, while decreasing the potential for damaging the inlet and outlet pipes, and/or the condenser.
Although the preferred embodiments of the invention have been illustrated and described in detail, it will be readily apparent to those skilled in the art that various modifications may be made therein without departing from the spirit of the invention or from the scope of the appended claims. For example, it should be readily apparent that the present invention may be adapted to retain a pair of pipes in fixed relation with a mounting surface, other than inlet and outlet pipes of a sub-cooled condenser system.
