Abstract
Description
- The present application claims priority from U.S. Provisional patent application Ser. No. 61/106,302, filed Oct. 17, 2008, the entire contents of which are hereby incorporated by reference.
- The present disclosure relates to systems and methods for managing air flow through an electronics equipment enclosure, and more particularly to systems and methods that block air from flowing through a selected internal area of an electronics equipment enclosure.
- The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. Open enclosure specifications targeting the communications equipment market, such as the PICMG AdvancedTCA specification, describe mechanical building practices utilizing Rear Transition Modules (RTMs). The RTMs are printed circuit board (PCB) modules, also referred to in the art as “blades”, that are contained with a rear (i.e. RTM) card cage area of a chassis. The RTMs are physically located behind a rear surface of a midplane that is positioned within the chassis RTM. On the opposite surface of the midplane is a front board card cage area. The front board card cage area has a plurality of card slots where one or more front boards, also sometimes referred to as “blades”, are electrically coupled to the midplane. The RTMs are electrically coupled to the front boards through a connector zone known in the art as the “Zone-3” area, which is located above the midplane when the RTMs and front boards are arranged in a vertical orientation.
- The main purpose of the RTMs is to support the rear input/output (I/O) interfaces, thus decoupling such interfaces from the processing activities of front boards and increasing the available PCB area for performing various functions. Cooling of the RTM card cage area of an AdvancedTCA specification chassis has been traditionally accomplished through natural convection cooling, that is, without the need for electrically powered cooling fans. However, as the power dissipation of the RTMs has increased, this has necessitated a move to forced convection cooling systems for the RTM card cage area. The associated mechanical specifications of an AdvancedTCA chassis have not been optimized with the goal of implementing optimal efficiency for the forced convection cooling of the RTM cardcage. Since some degree of variability is required to allow for variations in the thickness of the midplane due to differing midplane connectivity requirements, this has resulted in the creation of a relatively large gap. Thus, with present building practices for an AdvancedTCA chassis, the gap will typically exist between the midplane and the rear edges of the RTMs installed in the RTM card cage area of an enclosure.
FIG. 1 illustrates thisgap 2 within an AdvancedTCAspecification enclosure 8. Thegap 2 can be seen to exist between arear surface 4 a of themidplane 4 and arear edge 6 a of an RTM 6 within theenclosure 8. - The
gap 2 leaves unwanted low impedance, lateral air flow paths between the RTMs 6 and the midplanerear surface 4 a. Thegap 2 essentially acts like a low air flow impedance bypass path that allows a cooling air flow directed through the RTM card slots of the RTM card cage area to be diverted away from the RTMs 6. The existence of thegap 2 thus forms unwanted lateral flow paths that make the air flow distribution between the RTMs highly unpredictable. The air flow distribution through the RTM card cage area also becomes configuration specific, meaning that the configuration of the RTMs and their surface mounted components will play a significant role in determining the air flow distribution through the RTM card cage area. This is highly undesirable in an AdvancedTCA chassis where RTMs may be provided from multiple vendors, and therefore are not generally designed to take these effects into account. This can give rise to the need to independently verify each configuration of RTMs within the RTM card cage area, which is both time-consuming and costly, and which will need to be repeated for each subsequent configuration change. Existence of a low impedance air flow bypass path within the RTM card cage area also leads to wasted air flow and potentially to an insufficient volume of cooling air flow for the RTMs. - In one aspect the present disclosure includes an air flow restrictor panel adapted for use in an electronics equipment enclosure to block a gap existing between a midplane and an electronics module positioned adjacent the midplane. The air flow restrictor panel may incorporate a main panel portion and a plurality of flanges extending from the main panel portion. The main panel portion may have a footprint sufficiently large in area to block the gap.
- In another aspect the present disclosure includes an air flow restrictor panel adapted for use in an electronics equipment enclosure to block a gap existing between a midplane and an electronics module positioned adjacent the midplane. The air flow restrictor panel may include a main panel portion having a generally rectangular shape. A plurality of flanges may extend from the main panel portion. At least a subplurality of the flanges may each have a depth that is sufficient to substantially or entirely block a depth of the gap. The main panel portion may also have a footprint sufficiently large in length and height so as to block an area associated with the gap.
- In another aspect the present disclosure includes a method for restricting a flow of air between a gap existing between a midplane and an electronics module within an electronics equipment enclosure. The method may involve providing an air flow restrictor panel having a planar main panel portion. A plurality of flanges may be formed on the main panel portion such that the plurality of flanges extend from the main panel portion. At least a subplurality of the flanges each have a depth that is sufficient to substantially or entirely block a depth of the gap. The main panel portion may be formed with a footprint that is sufficiently large in length and height so as to block an area associated with the gap when the air flow restrictor panel is installed in the gap.

It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.
- Referring to
FIG. 2 , there is shown an airflow restrictor panel 10 in accordance with one embodiment of the present disclosure. For convenience, the airflow restrictor panel 10 will be referred to hereinafter simply as the “panel 10”. Thepanel 10 has a length “L” and height “H” that are sufficient to at least substantially, but more preferably completely, cover an area (i.e., length and height) associated with the gap, for example thegap 2 shown inFIGS. 1A and 1B . - The
panel 10 may include a generally planar and generally rectangular shapedmain panel portion 12 having a plurality ofcutouts 14 along anupper area 16. Thecutouts 14 in this example are each semi-circular in shape, but they could be of other shapes such as rectangular, square, elliptical, triangular, etc. Theupper area 16 also includesflanges 18 that extend at approximately a ninety degree angle from themain panel portion 12 between thecutouts 14.Side areas flanges main panel portion 12.Bottom area 28 likewise includes aflange 30 that extends at about a ninety degree angle from themain panel portion 12. - The
side areas tabs holes panel 10 to be secured the sidewalls of an electronic equipment enclosure, such as for example an AdvancedTCA specification chassis (e.g.,enclosure 8 inFIGS. 1A and 1B ). Thetabs main panel portion 12. Theupper area 16 similarly may includeholes 36 through which push-in type fasteners, rivets or threaded fasteners may extend to secure thepanel 10 within theenclosure 8. - The
flanges reference numeral 38 inFIG. 2 . The depth is further preferably equal to, or just slightly smaller (e.g., by 1-2 mm) than the depth of thegap 2, as indicated bydimensional arrows 40 inFIG. 1A . Thepanel 10 may be formed from steel, aluminum, plastic, rubber or any other material that is impervious to air flow. However, the use of metal provides specific benefits in terms of adding rigidity to theenclosure 8, enhancing overall structural integrity, enhancing fire resistance and limiting fire propagation. - Referring to
FIG. 3 , an electrically non-conductive, insulatingsheet 42 may be positioned over afront surface 44 of thepanel 10. The insulatingsheet 42 has dimensions andcutouts 46 that match (or substantially match) the configuration of thepanel 10. The insulatingsheet 42 provides a non-conductive barrier between therear edge 6 a of each RTM 6 and thefront surface 44 of thepanel 10 that ensures that no unwanted electrical contact will be made between therear edges 6 a of the RTMs 6 and thepanel 10. The insulatingsheet 42 may be formed from plastic or any other suitable, non-conductive material such as rubber. The insulatingsheet 42 may be secured to thepanel 10 by adhesives or by independent fasteners, for example push-intype fasteners 48, that extend through theholes 50 in the insulating sheet and alignedholes 36 in thepanel 10. The insulatingsheet 42 has an area (i.e., footprint) preferably sufficient to cover the entirefront surface 44 of thepanel 10. Instead of the insulatingsheet 42, thepanel 10front surface 44 may be coated with non-conductive paint or any other form of electrically non-conductive coating. However, if thepanel 10 is constructed from an electrically non-conductive material, then the insulatingsheet 42 would not be needed. - Referring to
FIG. 4 thepanel 10 can be seen installed against themidplane 4. Thepanel 10, with the help particularly of theflange 30, effectively fills the entire cross-sectional volume of thegap 2 so that the gap is eliminated. The installedpanel 10 positioned in theenclosure 8, without any - RTMs installed in the enclosure, is also shown in
FIG. 5 . FromFIG. 5 it can be seen that thecutouts 14 provide clearance for alignment pins 52 projecting from therear surface 4 a of themidplane 4. The alignment pins 52 aid in providing precise alignment of the RTMs 6 when the RTMs are being installed in the card slots in an RTMcard cage area 54. - The
panel 10 thus provides a structure and method for eliminating thegap 2, and thus ensuring that the cooling air flow directed into the RTM card cage area will flow through the RTM card slots in a predictable manner. A particular advantage of thepanel 10 is that it eliminates the need to perform RTM configuration specific testing to ensure that the desired air flow through the RTM card slots is being achieved. Furthermore, if the RTM configuration should be changed at a later date, no re-testing of the air flow through the RTM card cage area is required. Thepanel 10 further does not add appreciable cost, weight or complexity to the construction of an AdvancedTCA specification chassis, and can even enhance the structural properties of the chassis such as its rigidity and fire worthiness. - While various embodiments have been described, those skilled in the art will recognize modifications or variations which might be made without departing from the present disclosure. The examples illustrate the various embodiments and are not intended to limit the present disclosure. Therefore, the description and claims should be interpreted liberally with only such limitation as is necessary in view of the pertinent prior art.
