The Big Data Era,the rapid increase in IT equipment capacity has driven the development of high-density computing represented by blade servers, but it has also brought great challenges to cabinet heat dissipation and cooling. Based on the direct point-to-point connection of liquid cooling to data centers, the safety risk factor caused by liquid leakage is very high. Using separate cold and hot channel technology will reduce heat transfer efficiency, and natural cooling cannot cover the pain point all year round. With more than ten years of application experience in data center cooling and considering both safety and efficiency, TMF has launched a high security ELF Micro Block with direct cooling electronic fluorine liquid medium micro module solution for data centers.
