Hi
I would like to know what is the best way to cool Blade Chassis of 5 kW heat load.
What is the recommended CFM and temperature at inlet and exhaust of blade chassis?
Generally what is the capacity of fan built inside the blade chassis?

Hi
If you are talking about 1 blade chassis in an existing rack in a DC, it’s just the same as any other server.
The inlet temperature to almost all IT equipment is as stated in ASHRAE TC 9.9 that is: 18oC (65oF) to 27oC (80oF). The outlet temperature is something that you don’t need to worry about.
The fans inside the blade server (or any server really) will adjust their air flow to suit the cooling requirements, there is nothing that you need to do.
The best cooling system for blade chassis depends on the DC. Is this being installed into an existing DC? If so you will need to explain what cooling system is currently being used.
The outlet temperature is something that you don’t need to worry about.
You may want to care about outlet temperature depending on what your room arrangement consists of. Since blades put out a lot of heat, you want to be congnizant of where that heat is being dumped - hopefully not into an intake of another rack nearby.
If your plans include numerous blade servers, consider utilizing close-coupled in-row coolers (such as those made by APC), rear-door Heat Exchangers or a heat enclosure like Belden's heat containment chimneys.
Also, if the blades occupy only a portion of the rack, block out the unused rack space in the back for prevent hot exhaust from recirculating back to the front through the rack.
You are correct in that you need to manage the hot air from a rack, but this applies to any rack installation, not just Blades. Like any equipment to be installed, the DC must be capable of supporting the heat load.
There is a Myth in DC land that say’s Blades produce more heat and even higher temperatures than normal servers. The truth is that Blades will produce less heat when compared to the equivalent in pizza boxes or other servers. It is very easy to get a 30% power saving by using Blades, this means less heat.
From my experience I have found the Blades are easier to install, cable and manage when compared to any other IT equipment used in a DC.
instead of venting the exhaust heat from top of the rack, think of having hot aisle containment.
this would be easy to deploy and maintain as compare to venting exhaust air..
thanks.
Hello,
If you are racks load up to 35 kW of cooling, you need a high density cooling that won’t add heat to your room. The server rack system work maximize cooling efficiency without increasing the floor space. You can add or move cooling modules according to your equipment layout and as your needs grow.
