Abstract:
1. A memory module and heat spreader assembly comprising: a memory module of a computer, the memory module comprising a circuit board, and memory components on at least a first surface of the circuit board; and a heat spreader disposed at the first surface of the circuit board and bonded to the memory module, the heat spreader comprising a planar body, and a frame surrounding and offset from the planar body, the frame defining an outer extent of the heat spreader so as to define an interior space beneath the planar body for enclosing the memory components, the planar body contacting the memory components to provide conduction heat transfer from the memory components to the heat spreader, the heat spreader further comprising a grid defined in the planar body by perforations comprising at least a first plurality of uniformly distributed openings, the perforations extending through the planar body to allow natural air convention between the memory module within the interior space and an exterior space outside the heat spreader, wherein the perforations constitute about one-half or more of the surface area of the planar body.
