Abstract: Various embodiments include heat exchangers and methods of making heat exchangers from a series of stacked plates each made of two foil sheets bonded together in bonding locations forming fluid flow passages between the foil sheets in regions where the foil sheets are not bonded. An inlet port and an outlet port located at opposite ends of the planar extent of the two foil sheets extend through the foil sheets perpendicular to the planar extent of the foil sheets. The inlet and outlet ports provide access for a first fluid to flow into or out of the internal plate passages formed between the two foil sheets. Interstitial channels are formed between the series of plates and configured to allow the flow of a second fluid between the series of plates, allowing heat to be transferred between the two fluids while isolating the two fluids from one another.

Abstract: A multiple mode cooling system circulates outside air through a data center to cool heat-generating information technology (IT) component(s). Based on outside and interior air temperature values and outside humidity value, a controller determines that outside air cooling poses a risk of damage to the heat-generating IT component(s) due to condensation or overheating. Controller also determines that compressor(s) of the cooling system have been inactive for less than a minimum off-time specified for maintaining service life of the compressor(s). In response, controller checks a cooling mode setting and, based on determining that a cooling mode setting indicates an optimization preference for avoiding the posed risk of damage to the heat-generating IT component(s) over compressor service life, the controller restarts the compressor(s) before expiration of the minimum off-time.
