[0031] Reference will now be made in detail to the disclosed subject matter, which is illustrated in the accompanying drawings.

[0032] The data center market is moving away from raised floor designs, where the floor is installed below the data center equipment to allow the cabling and cooling air flow to travel below the floor to the equipment located on top of the floor. Balancing the temperature in the data center is important, however, moving away from raised floor designs creates difficulties for cooling units due to the reduced amount of space. In particular, the cooling units need to provide more air flow for proper distribution, which is difficult for conventional cooling units. For example, Figure 1A and Figure 1B As shown, in conventional cooling units, an external filter module (e.g., the upper portion of the cooling unit 100) is required to increase the surface area of ​​the filter, thereby increasing the size and cost of the cooling unit. Figure 1A In the example shown, the filter 102 is mounted in the upper portion of the cooling unit 100, wherein the coil 104 and the fan 106 are positioned a distance (e.g., about 1 meter or more) from the filter 102. In this regard, there is no direct contact between the coil 104 and the filter 102, which makes it difficult for the cooling unit 100 to provide an effective air flow for proper distribution. Figure 1B In the example shown, the filter 102 may be installed in an upper portion of the cooling unit 100 away from the compressor location 108. Therefore, it would be advantageous to provide a system or apparatus to remedy the disadvantages of the conventional methods described above.

[0033] Therefore, the present disclosure relates to a filter device for a cooling unit system in a data center. More specifically, the present disclosure relates to a filter device for a cooling unit system, wherein the filter device is installed / removed via a direct access opening on the cooling unit system. For example, the filter device can be bendable (or flexible) so that when the filter device is installed / removed from the direct access opening on the cooling unit system, the shape of the filter device conforms to the spatial limitations of the cooling unit system (e.g., the compact space within the cooling unit system, the arrangement of components within the cooling unit system, the size of the direct access opening, etc.). In this regard, the filter device can be installed in a spatially constrained location within the cooling unit system (the spatially constrained location was previously inaccessible) and can be easily replaced during maintenance via the direct access opening on the cooling unit system.

[0034] In addition, the present disclosure relates to a cooling unit system including a filter device, wherein the filter device is arranged in the cooling unit to be close to one or more coils. For example, the filter device can be positioned adjacent to one or more coils in the cooling unit system (e.g., directly above one or more coils or positioned near one or more coils). In this regard, one or more coils can be better utilized in the cooling unit system to improve the unit efficiency based on the close proximity of the filter device to the one or more coils. In addition, the filter area of ​​the filter device can be increased to reduce the air pressure drop, thereby reducing the fan power and improving the overall energy efficiency ratio (EER) of the cooling unit system. Therefore, the cooling unit system does not require an external filter module as previously discussed above with respect to a conventional cooling unit 100, so that the filter device can be installed in an existing data center where the overall height may be limited.

[0035] Figure 2A , Figure 2B and Figure 2C A simplified schematic diagram of a filter device 200 is illustrated in accordance with one or more embodiments of the present disclosure. Figure 2D A simplified schematic diagram of an array 201 of filter devices 200 is illustrated in accordance with one or more embodiments of the present disclosure.

[0036] Each filter device 200 may include one or more panels 202 formed from air filter media 204. For example, each panel 202 may be formed from pleated air filter media 204. The air filter media 204 may be any suitable air filter material, such as, but not limited to, paper, foam, carbon, aluminum, steel, fiberglass, plastic, etc.

[0037] Based on the configuration of the cooling unit system, each filter device 200 can include any number and any size of panels 202, as further discussed herein. In addition, it is contemplated herein that the size of the filter device 200 can vary based on the size / configuration of the cooling unit. In a non-limiting example, the length of the filter device 200 can be between about 1m and 3m.

[0038] Each filter device 200 may include one or more hinges 206 configured to allow the filter device 200 to bend (or fold) about an axis along the one or more hinges 206. For example, the one or more hinges 206 may include one or more living hinges configured to bend (or fold) about an axis along the one or more living hinges 206.

[0039] It is contemplated herein that for purposes of the present disclosure, a "hinge" (or variations thereof) may be any mechanical element or portion thereof that facilitates bending or folding relative to the body of the filter device 200 by construction, material type, reduced material thickness, etc. For example, one or more living hinges may be formed from one or more bendable filter materials such as, but not limited to, paper, foam, plastic, etc.

[0040] One or more hinges 206 may be disposed between one or more sections of one or more panels 202. For example, Figure 2C and Figure 2D As shown, one or more sections may include a first section 208a and a second section 208b, the first section 208a including a first panel 202a and a second panel 202b, and the second section 208b including a first panel 202a and a second panel 202b, wherein a first hinge 206a is disposed between the second panel 202b of the first section 208a and the first panel 202a of the adjacent section 208b. For example, the first section 208a including the first panel 202a and the second panel 202b may be bent around the first hinge 206a. In this regard, when the filter device 200 is installed in / removed from the cooling unit (as further discussed herein), the sections of the filter device 200 may be bent via the hinge 206, wherein each panel 202 remains substantially flat (e.g., not bent).

[0041] although Figure 2C and Figure 2DEach section 208a-208d is depicted as including two panels 202a, 202b, but it is contemplated herein that the filter device 200 may include any number of sections having any number of panels 202 (e.g., single panel, double panel, triple panel, etc.). Furthermore, it is contemplated herein that the filter device 200 may include any number of hinges 206 suitable for bending the filter device 200 to accommodate the configuration of a corresponding cooling unit, as further discussed herein. Thus, Figure 2C and Figure 2D It is provided for illustrative purposes only and should not be construed as limiting the scope of the present disclosure.

[0042] It is contemplated herein that one or more segments may be bent around a particular bending angle to accommodate the configuration of a corresponding cooling unit. For example, in a non-limiting example, the first segment 208a may have a first bending angle around the axis of the first hinge 206a, and the second segment 208b may have a second bending angle around the axis of the second hinge 206b. In some cases, the first bending angle of the first segment 208a may be similar to the second bending angle of the second segment 208b. In other cases, the first bending angle of the first segment 208a may be different from the second bending angle of the second segment 208b.

[0043] Each section 208a to 208d of the filter device 200 may include a support frame member 210. The support frame member 210 may be formed of a rigid material (e.g., cardboard, plastic, etc.) to provide support along the perimeter of the filter device 200. For example, Figure 2D As shown, each segment 208a to 208d may include a support member 210 along the edge of the segment, so that the perimeter of the segment 208a to 208d is formed by a plurality of support members 210. In this regard, when the segment is bent, one or more panels 202 of the corresponding segment are supported by the corresponding support member 210. In an embodiment, the support frame member 210 can strengthen the corresponding segment. Therefore, although the segment is strengthened, the hinge 206 can still allow the entire filter device 200 to be manipulated into place.

[0044] Figure 3A , Figure 3B , Figure 3C and Figure 3D A simplified schematic diagram of a cooling unit system 300 including one or more filter devices 200 is illustrated in accordance with one or more embodiments of the present disclosure. Figure 5A and Figure 5BA simplified schematic diagram of a cooling unit system 300 including one or more filter devices 200 according to one or more embodiments of the present disclosure is illustrated. For purposes of the present disclosure, the terms "cooling unit system 300," "cooling unit 300," "cooling system 300," "system 300," and variations thereof may be considered equivalent unless otherwise indicated herein.

[0045] One or more filter devices 200 may be installed in one or more cooling unit systems 300. For example, the cooling unit system 300 may include a cooling unit system such as Figure 2A , Figure 2B , Figure 2C and Figure 2D One or more individual filter devices 200 shown. In one example, the cooling unit system 300 may include a single filter device 200. In another example, the cooling unit system 300 may include a plurality of filter devices 200. As another example, the cooling unit system 300 may include a plurality of filter devices 200. Figure 2E An array 201 of filter devices 200 is shown. In one example, the cooling unit system 300 can include a single array 201 of filter devices 200. In another example, the cooling unit system 300 can include a plurality of arrays 201 of filter devices 200.

[0046] One or more filter devices 200 can be installed in one or more filter spaces 302 in the cooling unit system 300. For example, one or more filter spaces 302 can be arranged close to (or adjacent to) a coil location 304 in the cooling unit system 300, wherein the one or more filter spaces 302 can be at least partially defined by one or more surfaces of the coil location 304, so that when the filter device 200 is installed, the filter device 200 is arranged close to (or adjacent to) one or more coils 306. For example, as Figure 3B and Figure 5B As shown, one or more filter devices 200 can be arranged parallel to coil location 304, such that one or more filter devices 200 can be arranged to approach the entire length of one or more coils 306. In this regard, one or more filter devices 200 can be arranged above one or more coils 306 for front or downflow applications.

[0047] The cooling unit system 300 may include one or more coils 306 (also referred to as heat exchangers, condensers / evaporators, etc.). For example, the cooling unit system 300 may include a single coil 306. As another example, the cooling unit system 300 may include multiple coils 306, as further discussed herein. It is contemplated herein that the cooling unit system 300 may include any type of coil 306, so the above description and associated figures should not be interpreted as limiting the scope of the present disclosure. For example, the cooling unit system 300 may include a "v-coil" assembly, which includes one or more "v-shaped" coils. As another example, the cooling unit system 300 may include a plate coil assembly having one or more plate coils.

[0048] As previously discussed herein, existing filter devices are usually positioned to be greater than 1 meter from the coil. It is envisioned herein that one or more filter devices 200 can be closely approached to one or more coils 306 when installed, so that the gap between one or more filter devices 200 and one or more coils 306 is less than 1 meter. For example, one or more filter devices 200 can be in direct contact with one or more coils 306. For example, the gap between one or more filter devices 200 and one or more coils 306 may be minimal (e.g., there is no gap or there is very little gap). In a non-limiting example, one or more filter devices 200 can be positioned to be between about 0cm and 25cm from one or more coils 306. For example, one or more filter devices 200 can be positioned to be less than 10cm from one or more coils 306. In an example, one or more filter devices 200 can be positioned to be between about 6cm and 10cm from one or more coils 306. In another example, one or more filter devices 200 may be positioned approximately 1 cm from one or more coils 306 .

[0049] It is contemplated that the location of the filter device(s) 200 relative to the location of the coil 306 (e.g., direct contact between the filter device(s) 200 and the coil 306) provides a number of advantages. For example, the surface area of ​​the filter device(s) 200 is increased. As another example, air pressure drop is reduced. Furthermore, by placing the filter device(s) 200 above the coil, unit efficiency and cooling density are increased because the coil 306 is better utilized within the cooling unit system 300 due to the close proximity of the filter device to the coil.

[0050] It is contemplated that, given the size and location of the one or more filter spaces 302, the one or more filter spaces 302 may be considered spaces within the cooling unit system 300 that were previously inaccessible and incompatible with accommodating conventional filter devices.

[0051] The cooling unit system 300 may further include one or more fans 310. For example, the cooling unit system 300 may include a single fan 310. As another example, the cooling unit system 300 may include a plurality of fans 310.

[0052] One or more fans 310 may be located within one or more fan spaces 312 within the cooling unit system 300. For example, Figure 3B As shown, the fan space 312 can be arranged in the top portion of the cooling unit system 300. As another example, Figure 7B As shown and as further discussed herein, a fan space 312 may be disposed in a bottom portion of the cooling unit system 300 .

[0053] One or more filter devices 200 can be installed in or removed from the cooling unit system 300 via the direct access opening 314. For example, Figure 3B As shown, the direct access opening 314 can be arranged on the front surface (or front portion) of the cooling unit system 300. In this regard, one or more filter devices 200 can be installed in the cooling unit system 300 or removed from the cooling unit system 300 via the direct access opening 314 from the front surface (or front portion) of the cooling unit system 300.

[0054] Reference Figure 2C , Figure 2D and Figure 3C Each filter device 200 may be configured to be bent (or folded) so that the filter device 200 can be installed or removed via the gap space 301. The gap space 301 may be a very limited space (e.g., about 200 nm), making it difficult to remove / install the filter device 200 via the gap space 301. For example, Figure 3C As shown, the gap space 301 may be defined between the fan space 312 and a portion of the filter space 302 , wherein the filter device 200 may be configured to conform to the size of the gap space 301 , so that the filter device 200 may be removed from the filter space 302 or installed in the filter space 302 .

[0055] The direct access opening 314 can be coupled to a door 316. For example, the direct access opening 314 can be coupled to a rotatable door. Figure 3BAs shown, the door 316 may be opened to provide access to the filter device 200 within the cooling unit system 300 so that the filter device 200 may be installed in or removed from the space 302 within the cooling unit system 300 .

[0056] Refer again Figure 3A , the cooling unit system 300 can include an electrical panel located within the electrical panel location 318. Additionally, the cooling unit system 300 can include one or more ducts located within the duct location 320.

[0057] Reference Figure 5A , the cooling unit system 300 may include a refrigerant circuit location 322 configured to contain one or more refrigerants within the cooling unit system 300 .

[0058] Figure 4A , Figure 4B , Figure 4C and Figure 4D A schematic diagram of a method for extracting (removing) a filter device 200 from a space 302 within a cooling unit system 300 is depicted, in accordance with one or more embodiments of the present disclosure. Fig. 6A and Figure 6B A schematic diagram of a method for extracting (removing) a filter device 200 from a space 302 within a cooling unit system 300 is depicted, in accordance with one or more embodiments of the present disclosure.

[0059] For example, Figure 4A and Fig. 6A As shown, the filter device 200 can be installed (or disposed) within a space 302 within a cooling unit system 300. For example, the filter device 200 can be installed directly above a coil location 304, such that the filter device 200 is arranged to approach the entire length of one or more coils 306.

[0060] The filter device 200 can be bendable. For example, the shape of the filter device 200 can conform to the spatial limitations of the cooling unit system 300. For example, when the filter device 200 is pulled out from the direct access opening 314, the filter device 200 can be bent (or folded) so that when the filter device 200 is taken out, (one or more) corresponding sections can be bent via (one or more) corresponding hinges 206 based on the size / configuration of the gap space 301 of the direct access opening 314. In this regard, the planar portion of the filter device 200 can be within the space 302, wherein the filter device 200 is configured to be bent via the hinge 206 so that the filter device 200 can be removed from the limited space between the coil edge and the fan.

[0061] In a non-limiting example, Figure 4B As shown, the first section 208a of the filter device 200 can be bent via the first hinge 206a to pull the first section 208a of the filter device 200 out of the direct access opening 314. When the first section 208a is pulled out, the second section 208b of the filter device 200 can be bent via the second hinge 206b, wherein the plane portion 400 is located in the space 302 of the cooling unit system 300.

[0062] Continuing with the non-limiting example above, Figure 4C As shown, once the first section 208a and the second section 208b are pulled out, the third section 208c of the filter device 200 can be bent via the third hinge 206c to pull the third section 208c of the filter device 200 out from the direct access opening 314, wherein the planar portion 402 is located within the space 302 of the cooling unit system 300.

[0063] Continuing with the non-limiting example above, Figure 4D As shown, once the first section 208a, the second section 208b and the third section 208c are pulled out, the fourth section 208d of the filter device 200 can be bent via the fourth hinge 206d to pull the fourth section 208d of the filter device 200 out from the direct access opening 314, wherein the planar portion 404 is located within the space 302 of the cooling unit system 300.

[0064] Continuing with the non-limiting example above, although not shown, once the first section 208a, the second section 208b, the third section 208c and the fourth section 208d are pulled out, the fifth section of the filter device 200 can be bent via the fifth hinge to pull the fifth section of the filter device 200 out of the direct access opening 314 so that the entire filter device 200 is removed from the cooling unit system 300.

[0065] In a non-limiting example, the filter device 200 can be installed (or arranged) in the space 302 of the cooling unit system 300 by inserting the fifth section of the filter device 200 into the direct access opening 314, wherein the fifth section of the filter device 200 can be straightened via the fifth hinge. In this regard, the fifth section can form a planar portion in the space 302 of the cooling unit.

[0066] Continuing the above example, once the fifth section is installed, the fourth section can be inserted into the direct access opening 314, wherein the fourth section of the filter device 200 can be straightened via the fourth hinge. In this regard, the fifth section and the fourth section can form a planar portion within the space 302 of the cooling unit.

[0067] Continuing with the above example, once the fifth and fourth segments are installed, the third segment can be inserted into the direct access opening 314, wherein the third segment of the filter device 200 can be straightened via the third hinge. In this regard, the fifth, fourth and third segments can form a planar portion within the space 302 of the cooling unit.

[0068] Continuing with the above example, once the fifth, fourth, and third sections are installed, the second section can be inserted into the direct access opening 314, wherein the second section of the filter device 200 can be straightened via the second hinge. In this regard, the fifth, fourth, third, and second sections can form a planar portion within the space 302 of the cooling unit.

[0069] Continuing with the above example, once the fifth segment, the fourth segment, the third segment, and the second segment are installed, the first segment can be inserted into the direct access opening 314, wherein the first segment of the filter device 200 can be straightened via the first hinge. In this regard, the fifth segment, the fourth segment, the third segment, the second segment, and the first segment can form a planar portion within the space 302 of the cooling unit, so that the filter device 200 is completely installed (or completely disposed) within the space 302 of the cooling unit.

[0070] Fig. 7A , Figure 7B and Figure 7C A simplified schematic diagram of a dual coil cooling unit system 700 including one or more filter devices 200 according to one or more embodiments of the present disclosure is illustrated. It is contemplated herein that the above discussion regarding the cooling unit system 300 can be applied to the dual coil cooling unit system 700, and the discussion regarding the dual coil cooling unit system 700 can also be applied to the cooling unit system 300, unless otherwise specified herein.

[0071] The cooling unit 700 may include a plurality of coils 306 arranged in the coil positions 304, and one or more fans 310 arranged in the fan space 312. For example, the cooling unit 700 may include a dual-coil cooling unit 700 including at least two coils 306. For example, Figure 7B As shown, the dual-coil cooling unit system 700 may include at least a first coil 306a and a second coil 306b. In addition, the cooling unit 700 may include one or more fans 310 disposed below the plurality of coils 306.
