The present disclosure relates generally to information handling systems, and more particularly to a tooless heatsink retainer for use with such systems.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system (IHS). An IHS generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements may vary between different applications, IHSs 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 IHSs allow for IHSs 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, IHSs 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.
A heatsink is provided to remove heat from heat producing hardware including a processor in an IHS chassis. A surface of the heatsink is urged into contact with the processor to accomplish heat transfer from the processor to the heatsink. New processors are requiring larger forces and larger sockets for the processors to provide optimum operation. To achieve the larger forces required by the new processors, previous heatsink retention devices and methods have relied on labor intensive screw installation which requires tools, or a large footprint to achieve a tooless retention. What is needed is a device and method for applying a large force to a processor via the heatsink without requiring tools such as screwdrivers, and also having the ability to require a low level force by the user in applying the large force to the processor.
Accordingly, it would be desirable to provide an improved heatsink retainer absent the disadvantages discussed above.
According to one embodiment, for retaining a heatsink in contact with a processor on a board, a plurality of spaced apart mounting studs includes a pivotally mounted resilient arm and a resilient arm catch. A pair of the studs are positioned such that the resilient arm of one of the studs pivots to extend to engage the catch of an adjacent one of the studs.
For purposes of this disclosure, an IHS 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 IHS may be a personal computer, a PDA, a consumer electronic device, a network server or storage device, a switch router or other network communication device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The IHS 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 IHS 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 IHS may also include one or more buses operable to transmit communications between the various hardware components.
Other resources can also be coupled to the system through the memory I/O hub 104 using a data bus, including an optical drive 114 or other removable-media drive, one or more hard disk drives 116, one or more network interfaces 118, one or more Universal Serial Bus (USB) ports 120, and a super I/O controller 122 to provide access to user input devices 124, etc. The IHS 100 may also include a solid state drive (SSDs) 126 in place of, or in addition to main memory 108, the optical drive 114, and/or a hard disk drive 116. It is understood that any or all of the drive devices 114, 116 and 126 may be located locally with the IHS 100, located remotely from the IHS 100, and/or they may be virtual with respect to the IHS 100. Portions of the system 100 are provided in an IHS chassis 130,
Not all IHSs 100 include each of the components shown in

Although illustrative embodiments have been shown and described, a wide range of modification, change and substitution is contemplated in the foregoing disclosure and in some instances, some features of the embodiments may be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the embodiments disclosed herein.
