6 Can You Pack This into a Serverrack? This is our dilemma today Pizzas: å 12 kw 5 7U Blade Boxes: å 18 kw Ó by

7 Yes You can there is enough space in a 42 U Rack! Ó by

8 But: Can You Cool It? May be if there is enough cold air around it! Ó by

9 Can You Put It Into This Environment? You can but you cannot cool it! Ó by

10 The Limits of Air Cooling - High end datacenters today accommodate only. [HP] Maximum heat load : ~ W/m² ( W/sqft) = 3-4 kw / rack Ó by

11 Is This the Solution? 3,6 kw / rack 4 kw / rack Leave your racks empty? Build new datacenters? Ó by

12 Today The Room is also the Limit [Siemens Business Services] You cannot unleash a hurricane in a room But you can box it in a rack! Ó by

13 It's All About bringing the Cold closer to the Heat - Bring cooling to Enclosure level.not room Rack Liquid Cooling Ó by CPU Liquid Cooling

15 CoolTherm: Basic Function cooling water connection Ó by

16 The need to Shift to a new approach-water Comes Back...Capabilities of Liquid Cooling (1,000 Watt, DT = 10 C / 18 F) x 3.500! Heat transport ða small water tube can carry more heat than an entire room of air! In other words the amount of heat that can be removed by water is roughly 3,500 times which can be removed by the same volume of air. Security Water has been a standard and safe medium for heat transport in buildings and mainframes for decades. Flexibility Fluid cooling systems can be flexibly adapted to new cooling needs in the datacenter. Ó by

17 CoolTherm - Performance Data kw cooling capacity height up to 54 U / 2600 mm / 102" width 700 or 800 mm / 28 or 32" depth or mm / 48 or 52" 6 or 9U air/water heat exchanger cooling water temp. 12 / 18 C (54/65 F) l/s (6-14 USgal/min) water flow ~ 0.3 bar (4 PSI) pressure drop system pressure ~ 2 3 bar (30-45 PSI) closed air loop m³/h (1,200-3,250 cfm) air flow cooling air temp C (68-77 F) Þ ASHRAE Class 1 recommended envelope Ó by

18 CoolTherm - Main Advantages. ~ 0 heat disspation to the room uniform cooling air temperature over height, enhanced component lifetime for any 19" components water strictly under server compartment 2 or 3 fans / n+1 redundancy cooling control by fan speed monitoring of temperatures, water flow, fan speed, fire detection by RMS low noise emission enhanced protection against smoke, water vapor, high temperature in case of fire Ó by
