Abstract:
1. Apparatus for cooling of an electrical element package, comprising in combination a) structure including a hollow body, defining a cavity containing cooling fluid, b) the structure defining an opening or passage whereby direct contact of the cooling fluid with said package is established for heat transfer from the package to the fluid contained in the cavity, c) a mesh located to enhance said heat transfer, said mesh being in direct contact with said package d) and means for circulating the fluid to flow via the mesh and to transfer heat to other heat transfer means acting to remove heat from the fluid, e) and including a fluid seal between surfaces defined by said body and the package, adjacent said opening, f) said package including a heat spreader, g) and wherein said mesh is a first mesh, and including a second mesh receiving coolant fluid from the first mesh, for receiving heat therefrom and for transferring heat to heat dissipating means, h) and wherein said first mesh is substantially planar, and said coolant fluid flows within the first mesh in the direction or directions of planar extent thereof, and said second mesh is substantially planar and said coolant fluid flows within the second mesh in the direction or directions of planar extent thereof, i) said means having guide structure for guiding said fluid into the first mesh in a direction generally parallel to said lengthwise extent of the first mesh, and for channeling said flow within the first mesh into said direct contact with the package.
