Version 2<\/h2>\n<p><\/p>\n<p>The main complaint against the first version of the cooling system was its mechanics. For some reason, in the comments to the previous article with this photo:<\/p>\n<p><\/p>\n<p><img decoding=\"async\" alt=\"KTT in server solutions. The second version + announcement of the third, with a chance to try it out.\" src=\"\/wp-content\/uploads\/2019\/09\/8836628fcdcd4e2ebf54b93b857d5e2c.jpeg\" style=\"display:block;margin: 0 auto;\" \/><\/p>\n<p><\/p>\n<p>\u2026 no one particularly noticed that access to the entire right side of the server's rear panel becomes practically impossible. Only one observant reader suggested alternating the left-right placement of our fasteners.<\/p>\n<p><\/p>\n<p>The need to use such a monstrous fastener was caused by the desire to avoid thermal paste at the point where the heat exchanger exits the server to the vertical liquid bus. Thermal paste in such a removable connection is very undesirable. To avoid using it, significant pressing force is required.<\/p>\n<p><\/p>\n<p>In the second version, we implemented a different fastening system. The rail has become significantly more compact and has taken on a less 'made in USSR' appearance.<\/p>\n<p><\/p>\n<p><img decoding=\"async\" alt=\"KTT in server solutions.

The response to such concerns in the second version of our system was a protective casing.<\/p>\n<p><\/p>\n<p><img decoding=\"async\" alt=\"KTT in server solutions.

A step forward in safety. Now, no one can theoretically be doused with ethylene glycol, which fills the external heat exchange circuit.<\/p>\n<p><\/p>\n<p>The system is connected neatly. Without large flexible connections, as before. Such a design won\u2019t go anywhere, even if it\u2019s on wheels. The pipes are brought straight under the server rack, in the raised floor of the data center. <\/p>\n<p><\/p>\n<p><img decoding=\"async\" alt=\"KTT in server solutions.

In the previous post, we were sparse on photos of the internals. We'll try to improve on that now.<\/p>\n<p><\/p>\n<p>Here is how a server pulled out of the rack looks with our cooling system.
