Why did Knürr decide to position the heat exchanger on the rack bottom cover and not on the roof or in one of the side or rear panels?
The main reason for this is the consequential securing of the system against leakage risks. Water-carrying components are exclusively positioned with CoolTherm® on the lowest level of the rack where the connection to the cooling water system is made. Even with a leakage (which is highly improbable), water can never reach the electronic components. Positioning on the roof is therefore ruled out in every case. This argument also applies with add-on on the side or in one of the doors, if perhaps, with limits. One argument against add-on on the side panel is the fact that the rack no longer fits into the spacing of the rack suites in the computer centre because of its considerably increased width. Also the evenly distributed air before the server level can not be ensured with a vertical inlet. Overall, installation on the lowest level of the rack is the most compact, most cost-efficient and safest solution.
