Why Not Just Shove a Heatsink on Top of it? Part 3: Pads, Vias and Undersinking
An appreciation of heat flow paths is a pre-requisite for good thermal design. If you attempt to augment heat flow where there is none then your expectations are as futile as your design skills. The real value of simulation for me is that it enables an insight into the behaviour of a proposed design (this is true for simulation of any design and any behaviour). Once you … [Read more...]
Thermal Spreading and More Using Open-Source FEA Software
The purpose of the present article is to suggest that accurate solution of thermal spreading problems for multilayer, edge-truncated geometry is easily accomplished using free, open-source finite element software. This should be especially attractive to designers and analysts who are full-time independent consultants, temporary contractors, or regularly employed … [Read more...]
Two-Phase Flow Control of On-Chip Two-Phase Cooling Systems Developed for Blade Servers of Data Centers
Server manufacturers and data center managers are showing a greater concern regarding the energy efficiency and cooling of the new generation of servers for data centers. With very large data centers exceeding 100 000 servers, some even consuming more than 50 MW [1] to operate, this electrical energy is directly converted to heat and then simply “wasted” as it is dissipated … [Read more...]
Thermal Facts and Fairy Tales: A System Perspective for Electronics Cooling
A friend of mine who was an aspiring plumber once stated that all you need to know to be a plumber is that you get paid on Friday and that waste flows downhill. Maybe there is a similar analogy for thermal engineers that regardless of when we get paid, thermal energy will flow in the direction of decreasing temperature. The direction of heat flow with respect to temperature … [Read more...]
