DETAILED DESCRIPTION
[0035] Referring to FIGS. 1-7, a heat exchanger 100 is illustrated.
The heat exchanger 100 may be used in conjunction with an assembly
or system of a vehicle, such as an aircraft, however, it is
contemplated that other vehicles may benefit from the embodiments
described herein. In one embodiment, the heat exchanger 100 is part
of an air conditioning system or refrigeration system of an
aircraft.
[0036] The heat exchanger 100 includes a core assembly 150 disposed
within the housing 120 and removably connected to the housing 120.
The core assembly 150 may be removably connected to the housing 120
by a plurality of fasteners 190, as seen in FIG. 1. The housing 120
includes a top portion 120a, a bottom portion 120b, an inner
surface 120c, and an outer surface 120d. The housing 120 may also
include a mounting point 104 to mount the housing 120 to a
structural support, such as, for example, a structural frame of an
aircraft. The housing 120 also includes a first housing inlet 122
for a first fluid 10, such as, for example, cold air from an air
cycle machine (ACM) turbine (not shown). A mixer 110 may be located
at the first housing inlet 122, as seen in FIGS. 1-3, 5, and 7. The
housing 120 also includes a first housing outlet 128 for the first
fluid 10 to exit the heat exchanger 100. The first housing outlet
128 may lead the first fluid 10 overboard or outside a vehicle. A
first fluid passage 153, located in the core assembly 150, fluidly
connects the first housing inlet 122 to the first housing outlet
128. Thus, the first fluid 10 flows F1 from an ACM turbine through
the mixer 110 and into the core assembly 150 through the first
housing inlet 122. Once the first fluid 10 has flowed F6 through
the first fluid passage 153 of the core assembly 150, the first
fluid 10 flows F5 out of the heat exchanger 100 through the first
housing outlet 128.
[0037] Additionally, the housing includes a second housing inlet
124 for a second fluid 20, such as, for example, warm air from an
ACM compressor (not shown). The housing 120 also includes a second
housing outlet 126 for the second fluid 20 to exit the heat
exchanger 100. The second housing outlet 126 may lead the second
fluid 20 to a cabin of a vehicle or aircraft. A second fluid
passage 163, located in the core assembly 150, fluidly connects the
second housing inlet 124 to the second housing outlet 126. Thus,
the second fluid 20 flows F2 from an ACM compressor into the core
assembly 150 through the second housing inlet 124. Once the second
fluid 20 has flowed F3 through the second fluid passage 163 of the
core assembly 150, the second fluid 20 flows F4 out of the heat
exchanger 100 through the second housing outlet 126.
[0038] The core assembly 150 includes a top side 150a, a bottom
side 150b, an inner surface 150c, and an outer surface 150d. The
bottom side 150b of the core assembly 150 abuts the bottom portion
120b of the housing 120 when the core assembly 150 is disposed
within the housing 120. The core assembly 150 includes core 160
having a first fluid passage 153 having a first core inlet 154 and
a first core outlet 156. As may be appreciated by one of skill in
the art, the core 160 may include various designs for the exchange
of heat between the first fluid passage 153 and the second fluid
passage including various core types and header types. The core
assembly also includes a second fluid passage 163 having a second
core inlet 164 and a second core outlet 166. The first fluid
passage 153 is thermally connected to the second fluid passage 163.
When the core assembly 150 is disposed within the housing 120 the
first core inlet 154 is aligned with the first housing inlet 122,
the second core inlet 164 is aligned with the second housing inlet
124, the first core outlet 156 is aligned with the first housing
outlet 128, and the second core outlet 166 is aligned with the
second housing outlet 126 as seen in FIG. 3. A first seal 172 is
interposed between the bottom side 150b of the core assembly 150
and the bottom portion 120b of the housing 120, as seen in FIGS. 4
and 7. The first seal 172 is configured to seal the fluid
connections between the second housing inlet 124 and the second
fluid passage 163 and the fluid connection between the second core
outlet 166 and the second fluid passage 163. In other words, the
first seal 172 is configured to seal the fluid connections between
the second housing inlet 124 and the second core inlet 164 and also
seal the fluid connection between the second core outlet 166 and
the second housing outlet 126. In an embodiment, the first seal 172
may be a compression seal and/or hollow tube seal.
[0039] Proximate the outer surface 150d of the core assembly 150
portions, of the first fluid passage 153 and the second fluid
passage 163 that compose the core 160 may form an outer edge 155 of
the core 160. The outer edge 155 may provide additional structural
support to the core assembly 150. The outer edge 155 may include a
knife edge 155a proximate the bottom 150b of the core assembly 150.
The knife edge 155a is configured to compress the first seal 172.
The outer edge 155, may also include rings 155b configured to fit
around a tapered pin 130, as seen in FIG. 4. In the illustrated
embodiment, the heat exchanger 100 includes four tapered pins 130
affixed to the bottom portion 120b of the housing 120. The tapered
pins 130 are configured to help align the core assembly 150 within
the housing 120. As the core assembly 150 is inserted into the
housing 120 the rings 155b slide in around the tapered pins 130. In
operation, heat may cause the core assembly 150 to expand and
contract and as this occurs the rings 155b are free to slide up D1
and down D2 on the pins.
[0040] In the illustrated embodiment the core 160 has a two pass
design where the second fluid passage 163 of the core assembly 150
includes at least two passes across the flow direction F6 of the
first fluid passage 153. The two pass design allows the second
fluid 20 to flow F3 through the core 160 twice within the second
fluid passage 163 before exiting the core 160. The second fluid
passage 163 utilizes a domed header 157, located at the top side
150a, to redirect the flow F3 one-hundred and eighty degrees from
the second core inlet 164 to the second fluid exit 166, thus
allowing the second fluid 20 to pass through the core 160 twice.
The first fluid 10 flows F6 through the first fluid passage 153,
which is arranged perpendicular to the second fluid passage 163. As
may be appreciated by one of skill in the art there may be multiple
first fluid passages 153 and multiple second fluid passages 163;
however a single first fluid passage 153 and a single second fluid
passage 163 are shown for simplicity. Further, as may be
appreciated by one of skill in the art the core 160 may include a
variety of different fin designs and patterns for the first fluid
passage 153 and the second fluid passage 160 to achieve the desired
thermal transfer between the fluid passages 153, 163.
[0041] As mentioned above, the core assembly 150 is removably
connected to the housing 120, which means that the core assembly
150 may be inserted into the housing 120 and secured to the housing
120; and then the core assembly 150 may be unsecured from the
housing 120 and removed from the housing 120. As also mentioned
above, the core assembly 150 is secured to the housing 120 by a
plurality of fasteners 190. As seen in FIG. 2, a core flange 159 on
the core assembly 150 mounts onto an opposing mounting flange 129
on the housing 120 and the fasteners 190 secure the core flange 159
to the mounting flange 129. The mounting flange 129 is located
proximate the top portion 120a of the housing 120. In an
embodiment, the fasteners may be a bolt that screws into
pre-drilled holes in the mounting flange 129. A second seal 174 is
interposed between the core flange 159 and the mounting flange 129,
as seen in FIG. 3. The second seal 174 is configured to act as a
gasket and seal the interface between the core flange 174 and the
mounting flange 129. The second seal 174 may be composed of an
elastomeric material.
[0042] The core assembly 150 also includes a plurality of corner
seals 180 located at each corner 150e of the core assembly 150, as
seen in FIG. 5, to provide air sealing at each corner 150e when the
core assembly 150 disposed within the housing 120. The corner seals
180 may also help guide the core assembly 150 during installation
and removal of the core assembly 150 from the housing 120. The
corner seals 180 are configured to seal the interface between an
inner surface 120c of the housing 120 and an outer surface 120d of
the core assembly 150 when the core assembly 150 is disposed within
the housing 120. The corner seals 180 may be composed of an
elastomeric or similar material. The corner seals 180 may have a
corner fitting 186 help fit with each corner 150e of the core
assembly 150. The corner seals 180 may be fixedly connected to the
outer surface 150d of the core assembly 150 at each corner 150e.
The corner seals 180 may be fixedly connected to the outer surface
150d by an adhesive (not shown) applied between the corner fitting
186 and the corner 150. The corner seal 180 may also include teeth
182, as seen in FIG. 6, to aid in sealing between the corner seal
180 and the inner surface 120c of the housing 120. The teeth 182
may also slide relative to the inner surface 120c of the core
assembly 150 is inserted into the housing 120 and removed from the
housing 120. Additionally, the corner seal 180 may include a center
core 188. Advantageously, the center core 188 may aid in
compression and also provide weight savings. In the illustrated
embodiment, the core assembly 150 is cuboid in shape having six
sides including the top side 150a and an opposing bottom side 150b
having the second core inlet 164 and the second core outlet 166.
The four sides interposed between the top side 150a and the bottom
side 150b includes two opposing side walls 151, the first core
inlet 154, and the first core outlet 156. The corner seals 180 are
each located at the four corners 150e of the four sides interposed
between the topside 150a and the bottom side 150b.
[0043] Referring now to FIG. 8, while referencing components of the
heat exchanger 100 of FIGS. 1-7, FIG. 8 shows a flow process
illustrating a method 800 of assembling the heat exchanger 100 of
FIGS. 1-7. At block 804, the housing 120 is formed. The housing 120
may be formed by various manufacturing methods including but not
limited to molds, machining, additive manufacturing, and/or any
other method known to one of skill in the art. As discussed above,
the housing has a first housing inlet 122, a second housing inlet
124, a first housing outlet 128, and a second housing outlet 126.
At block 806, the core assembly 150 is positioned within the
housing. As mentioned above, the core assembly 150 comprises a
first fluid passage 153 fluidly connecting the first housing inlet
122 to the first housing outlet 128 and a second fluid passage 163
fluidly connecting the second housing inlet 124 to the second
housing outlet 126. The first fluid passage 153 is thermally
connected to the second fluid passage 163.
[0044] At block 808, the core assembly 150 is removably connected
to the housing 120. As discussed above, fasteners 190 may be used
to removably connect the core assembly 150 to the housing 120. At
block 810, the mounting flange 129 is formed on the top portion
120a of the housing 120. The top portion 120a is opposite the
bottom portion 120b. As mentioned above, the core assembly 150
further comprises a top side 150a having a core flange 159 and an
opposing bottom side 150b. The core flange 159 mounts onto the
opposing mounting flange 129 and the bottom side 150b of the core
assembly 150 abuts the bottom portion 120b of the housing 120 when
the core assembly 150 is disposed within the housing 120.
[0045] At block 812, the first seal 172 is positioned interposed
between the bottom side 150b of the core assembly 150 and the
bottom portion 120b of the housing 120. The first seal 172 being
configured to seal the fluid connection between the second housing
inlet 124 and the second fluid passage 163 and seal the fluid
connection between the second housing outlet 126 and the second
fluid passage 163 when the core assembly 150 is disposed within the
housing 120. At block 814, the second seal 174 is positioned
interposed between the flange 159 of the core assembly 150 and the
mounting flange 129 of the housing 120.
[0046] While the above description has described the flow process
of FIG. 8 in a particular order, it should be appreciated that
unless otherwise specifically required in the attached claims that
the ordering of the steps may be varied.
