- 1. Technical Field
- The present disclosure relates to a heat dissipation assembly and a latch apparatus of the heat dissipation assembly.
- 2. Description of Related Art
- An electronic device, such as a computer or a server, includes a motherboard, and a number of electronic elements such as central processing units and memories arranged on the motherboard. A heat sink is usually mounted on the motherboard and attached on one electronic element for heat dissipation. Most heat sinks are configured to fit one type of motherboard, so a different type of motherboard needs a different type of heat sink.
- Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
