Abstract

The invention involves systems to channel the air available for cooling inside the chassis of the computing device to force the air into selected channels in the memory bank (i.e., between the modules rather than around the modules or some other path of least resistance). This tunneled cooling (or collimated cooling) is made possible by using a set of baffles (or apertures) placed upstream of and between the cooling air supply and the memory bank area to force air to go only through the rectangular space available between adjacent modules in the memory bank of the high speed computing machines (super computers or blade servers in these cases). In some instances, it may be desirable to include both a blower fan, for forcing cool air through the baffles and through the heat exchanger(s) aligned with openings in the baffles, and a suction fan to draw or pull air as it exits the rear of the blade server chassis. The invention includes a high performance heat exchanger to be thermally coupled to the memory chips and either placed between adjacent modules (in the memory bank) or integrated within a cross sectional area of the module that is in the cooling air path; whereby, the heat from a given module is transferred laterally to a heat sink that, in turn, transfers the heat to the heat exchanger which in turn is placed in the path of cool air. However in this case, the cool air has no other alternative path but to pass through the high performance heat exchanger. The efficiency of heat exhaust is thereby maximized. Lateral heat conduction and removal is a preferred method for module cooling in order to minimize the total module height of vertically mounted Very Low Profile (VLP) memory modules. The invention is applicable to a wide range of modules; however, it is particularly suitable for a set of memory modules with unique packaging techniques that further enhance the heat exhaust.
