Abstract

This disclosure describes a heatsink with design features that permit easy installation and removal. The design features help ensure appropriate orientation and location of the heatsink in a larger system. The design features include a handle oriented transverse to an air flow direction in a system in which the heatsink is included. The handle facilitates independent installation and removal of individual heatsinks. The heatsinks may include visual clues and physical keying to ensure proper orientation of the heatsink to module assembly. The visual clues and physical keying ensure proper orientation and location when the heatsink and module assembly is inserted into a larger system such as a server. The heatsink can also reduce the amount of air that bypasses the heatsink, which can improve cooling efficiency.

BACKGROUND

    Heatsinks are used to remove heat from computer processors, such as central processing units (CPUs) and graphics processing units (GPUs). During operation of a processor, a heatsink ensures that the processor operating temperature remains within a desired range. Heatsinks can be installed along with processor modules at a time of

physically setting up a computer server. Heatsinks can suffer failure during operation and may have to be replaced.

    Installation and removal of heatsinks may be performed manually. Ensuring proper orientation and location of a heatsink within a larger system, e.g., a system that includes multiple processor modules and heatsinks, may be facilitated with appropriate design features.

DESCRIPTION

Heatsink Array

    Fig. 1 shows a top view of an example system with an array of heatsinks. The system includes back row processors and front row processors, each arranged in a respective row. Heatsinks 102a-102d are effective to remove heat from the back row processors. Heatsinks 104a-104d are effective to remove heat from the front row processors.

    In this system, most sides of each heatsink are adjacent to another heatsink or a side- wall of the system. In the example shown in Fig. 1, heatsink 102b is adjacent to heatsink 102a on one side and to heatsink 102c on another side. Further, heatsink 104a is adjacent on one side with a side-wall and on another side with heatsink 104b. When the system is being serviced, it is difficult for a service technician to grasp two opposite sides of an individual heatsink to lift it out of the system or to place it into the system, because the minimal gap between sides of adjacent heatsinks provides limited space to manipulate an individual heatsink.

    The heatsink of this disclosure permits easy grasping by including a handle in the top surface of the heatsink, as shown in Fig. 2 below.
