Patent Application
20240023236
The present disclosure relates in general to information handling systems, and more particularly to a circuit board assembly with an integrated airflow path.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Information handling systems are becoming more and more dense over time, both from a hardware feature and power density perspective. In each subsequent generation of information handling systems, more features are added and the power consumption of those features also increases from generation to generation. Air cooling remains the predominant cooling solution for rack servers, but due to the system and power density trends, air cooling is becoming more and more difficult. Accordingly, systems and methods that enable efficient routing of airflow in an information handling system may be desired.
In accordance with the teachings of the present disclosure, the disadvantages and problems associated with existing approaches to routing of airflow in information handling systems may be reduced or eliminated.
In accordance with embodiments of the present disclosure, a circuit board assembly may include an integrated airflow path formed with a partially closed volume to direct airflow received at a first opening of the integrated airflow path through the integrated airflow path and to a second opening of the integrated airflow path, a circuit board mechanically coupled to the integrated airflow path such that at least a portion of the circuit board resides within the partially closed volume, and a connector electrically and mechanically coupled to the circuit board and configured to electrically and mechanically couple a device received in the connector to the circuit board.
In accordance with these and other embodiments of the present disclosure, an information handling system may include an information handling resource and a circuit board assembly comprising an integrated airflow path formed with a partially closed volume to direct airflow received at a first opening of the integrated airflow path through the integrated airflow path and to a second opening of the integrated airflow path, a circuit board mechanically coupled to the integrated airflow path such that at least a portion of the circuit board resides within the partially closed volume, and a connector electrically and mechanically coupled to the circuit board and configured to electrically and mechanically couple the information handling resource received in the connector to the circuit board.
In accordance with these and other embodiments of the present disclosure, a method may include forming an integrated airflow path with a partially closed volume to direct airflow received at a first opening of the integrated airflow path through the integrated airflow path and to a second opening of the integrated airflow path, mechanically coupling a circuit board to the integrated airflow path such that at least a portion of the circuit board resides within the partially closed volume, and electrically and mechanically coupling a connector to the circuit board and configured to electrically and mechanically couple a device received in the connector to the circuit board.
Technical advantages of the present disclosure may be readily apparent to one skilled in the art from the figures, description and claims included herein. The objects and advantages of the embodiments will be realized and achieved at least by the elements, features, and combinations particularly pointed out in the claims.
It is to be understood that both the foregoing general description and the following detailed description are examples and explanatory and are not restrictive of the claims set forth in this disclosure.
A more complete understanding of the present embodiments and advantages thereof may be acquired by referring to the following description taken in conjunction with the accompanying drawings, in which like reference numbers indicate like features, and wherein:
Preferred embodiments and their advantages are best understood by reference to
For the purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, entertainment, or other purposes. For example, an information handling system may be a personal computer, a personal data assistant (PDA), a consumer electronic device, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include memory, one or more processing resources such as a central processing unit (CPU) or hardware or software control logic. Additional components of the information handling system may include one or more storage devices, one or more communications ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more buses operable to transmit communication between the various hardware components.
For the purposes of this disclosure, computer-readable media may include any instrumentality or aggregation of instrumentalities that may retain data and/or instructions for a period of time. Computer-readable media may include, without limitation, storage media such as a direct access storage device (e.g., a hard disk drive or floppy disk), a sequential access storage device (e.g., a tape disk drive), compact disk, CD-ROM, DVD, random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), and/or flash memory; as well as communications media such as wires, optical fibers, microwaves, radio waves, and other electromagnetic and/or optical carriers; and/or any combination of the foregoing.
For the purposes of this disclosure, information handling resources may broadly refer to any component system, device or apparatus of an information handling system, including without limitation processors, service processors, basic input/output systems (BIOSs), buses, memories, I/O devices and/or interfaces, storage resources, network interfaces, motherboards, power supplies, air movers (e.g., fans and blowers) and/or any other components and/or elements of an information handling system.
As discussed above, an information handling system may include one or more circuit boards operable to mechanically support and electrically connect electronic components making up the information handling system (e.g., packaged integrated circuits). Circuit boards may be used as part of motherboards, memories, storage devices, storage device controllers, peripherals, peripheral cards, network interface cards, and/or other electronic components. As used herein, the term “circuit board” includes printed circuit boards (PCBs), printed wiring boards (PWBs), etched wiring boards, and/or any other board or similar physical structure operable to mechanically support and electrically couple electronic components.
As also shown in
As an example, in some embodiments, circuit board 104 may comprise a riser card configured to receive a multitude of signal lines (e.g., bused signal lines) via a single connector (e.g., an edge connector of the riser card external to integrated airflow path 102) from a motherboard and distribute such signals lines via dedicated connectors (e.g., one or more receptacle connectors 106) mounted on the riser card. Thus, when implemented as a riser card, circuit board 104 may enable the addition of expansion cards (e.g., Peripheral Component Interconnect Express or “PCIe” cards), particularly where a height of an information handling system chassis does not allow for a perpendicular placement of expansion cards relative to the motherboard.
