In some embodiments, a management controller may be (or may be an integral part of) a baseboard management controller (BMC), a chassis management controller (CMC), or a remote access controller (e.g., a Dell Remote Access Controller or Integrated Dell Remote Access Controller).

(15) FIG. 1 illustrates a block diagram of an example information handling system 102, in accordance with embodiments of the present disclosure. In some embodiments, information handling system 102 may comprise a server chassis configured to house a plurality of servers or blades. In other embodiments, information handling system 102 may comprise a personal computer (e.g., a desktop computer, laptop computer, mobile computer, and/or notebook computer). In yet other embodiments, information handling system 102 may comprise a storage enclosure configured to house a plurality of physical disk drives and/or other computer-readable media for storing data (which may generally be referred to as physical storage resources). As shown in FIG. 1, information handling system 102 may comprise a processor 103, a memory 104 communicatively coupled to processor 103, a Basic Input/Output System (BIOS) 105 (e.g., a Unified Extensible Firmware Interface (UEFI) BIOS) communicatively coupled to processor 103, a network interface 108 communicatively coupled to processor 103, and a management controller 112 communicatively coupled to processor 103.

Network interface 118 may be the same type of device as network interface 108, or in other embodiments it may be a device of a different type.

(24) Turning now to FIG. 2, information handling system 202 is shown. Information handling system 202 may be an example of a physical embodiment of information handling system 102, including various information handling resources 204. Air movers (not shown explicitly) may generate airflow to cool one or more of information handling resources 204, as well as information handling system 202 in general.

(25) As shown, information handling system 202 is contained within a chassis such that airflow proceeds in the direction indicated by arrows. In the configuration shown, one side of the chassis does not contain any information handling resources that need cooling, and so it may be advantageous to direct all of the available airflow away from that region to increase airflow in the more temperature-critical regions. Accordingly, air baffle 252 may be used to block a portion of the front grille of the chassis to prevent airflow from going to waste by entering such region via the air inlet at the front grille.

(26) Similarly, air baffle 254 may be used at the rear grille of the chassis to allow the airflow to expand in such a way as to use all of the available exhaust space. This may reduce backpressure, increasing airflow velocity and overall cooling efficiency. Thus in these embodiments, air baffles may be placed proximate to an air inlet and/or exhaust. For purposes of this disclosure, this term is defined to mean that at least a portion of the air baffle is within 1 centimeter of such air inlet or exhaust, respectively.

(27) Further, in some embodiments, air baffles 252 and 254 may be placed such that internal leakage paths are reduced or eliminated.

(28) Turning briefly to FIG. 4, FIGS. 4B and 4C provide detail views of air baffles 252 and 254, respectively. These detail views illustrate how air baffles 252 and 254 are folded into the desired shapes shown in FIG. 2. Similarly, FIG. 4A provides a detail view of air baffle 200, which is an air baffle of the same design, but which has not been folded.

(29) Air baffles 252 and 254 may in some embodiments be identical in design and construction. In some embodiments, they may be made of a BoPET (Mylar) material, metals, plastics, or any other suitable material (either alone or in combination). As shown, a plurality of folding lines 212 may be included to allow air baffles 252 and 254 to be folded into a desired configuration. Folding lines 212 may in some embodiments be implemented as a portion of the air baffle that is made from the same material, but a thinner version, such that the air baffle may more easily be folded at those locations.

(30) In some embodiments, these folding lines 212 may be arranged at regular intervals with a constant spacing (such as 10 millimeters, or any other suitable spacing). In other embodiments, the spacing between the folding lines 212 need not be constant. In yet other embodiments, an air baffle according to the present disclosure may include only a single folding line 212.

(31) In the embodiment shown in FIG. 2, folding lines 212 may be parallel or substantially parallel to one another, and they may be directed along a direction of the height of air baffles 252 and 254. (For purposes of this disclosure, the term substantially parallel is defined to mean that elements are within five degrees of being parallel.) In other embodiments, the folding lines may be disposed in other arrangements to create air baffles that are foldable into other shapes. One of ordinary skill with the benefit of this disclosure will be able to envision many possibilities for the locations of folding lines 212.

(32) Air baffles 252 and 254 may be folded at any or all of the folding lines, to form any desired angle(s). Thus air baffles 252 and 254 may be very adaptable in terms of the chassis designs and configurations they support.

(33) The detail views of FIG. 4 also highlight the use of tool-less mounting features 210.

(34) Air baffles 252 and 254 may include such tool-less mounting features 210 to support effortless mounting in various locations and in various types of chassis configurations. For example, a hole may be used as a tool-less mounting feature 210, and a stud may be pressed through such a hole and into a corresponding feature of a chassis wall or other chassis feature to secure an air baffle in place. In other embodiments, different types of mounting solutions may be used, with or without the use of tools. One of ordinary skill in the art with the benefit of this disclosure will understand many possibilities for mounting air baffles into a chassis.

(35) Turning now to FIG. 3, another example information handling system 302 is shown. Information handling system 302 may be generally similar to information handling system 202, with information handling resources 304 corresponding to information handling resources 204. Accordingly, for the sake of brevity, only the differences will be described in detail.

(36) The main difference in information handling system 302 is the addition of information handling resource 306. This addition creates the need for a different cooling solution, as compared with information handling system 202.

(37) Accordingly, air baffle 256 has taken the place of air baffle 252. Air baffle 256 is configured to block a smaller portion of the front grille of the chassis. Similarly, air baffle 258 has taken the place of air baffle 254. Air baffle 258 has been folded in such a way that it allows for cooling of information handling resource 306, but also causes the airflow to expand to use all available exhaust space.

(38) FIGS. 4D and 4E provide detail views of air baffles 256 and 258, respectively. These detail views illustrate how air baffles 256 and 258 are folded into the desired shapes that are shown in FIG. 3.

(39) As noted above, air baffles 200, 252, 254, 256, and 258 may all be identical in design and construction. The existence of folding lines 212 allows this single design to be used in different circumstances by allowing the air baffles to be folded as needed.

(40) In some embodiments, an air baffle according to the present disclosure may be reusable. For example, an air baffle may be removed from a particular chassis, folded into a different shape, and then re-mounted in a different chassis (or a different location within the same chassis).

(41) This disclosure encompasses all changes, substitutions, variations, alterations, and modifications to the exemplary embodiments herein that a person having ordinary skill in the art would comprehend. Similarly, where appropriate, the appended claims encompass all changes, substitutions, variations, alterations, and modifications to the exemplary embodiments herein that a person having ordinary skill in the art would comprehend.

(42) Further, reciting in the appended claims that a structure is configured to or operable to perform one or more tasks is expressly intended not to invoke 35 U.S.C. 112(f) for that claim element. Accordingly, none of the claims in this application as filed are intended to be interpreted as having means-plus-function elements.
