[Three HVAC giants’ “variable frequency” entry into the 100-billion-dollar liquid cooling track] On October 28, traditional air cooling entered the stock market, and the demand for AI computing power detonated the 100-billion-level liquid cooling market. HVAC giants represented by Gree, Midea, and Haier are accelerating the "cross-border" to "frequency conversion" in liquid cooling and entering a new track. The reporter's investigation found that since this year, Gree has established a joint venture with Sinnet, the leading domestic IDC service provider, focusing on the market of liquid cooling refrigeration systems, high-performance computing equipment and cloud computing facilities; Midea has invested 1 billion yuan in a new liquid cooling intelligent manufacturing base in Shunde, planning to build 12 professional liquid cooling production lines; Haier has invested more than 1 billion yuan to lay out a data center production base in Rayong, Thailand. At present, liquid cooling has changed from an "option" for AI servers in data centers to a "must have". With the cold source technology and manufacturing capabilities accumulated in the HVAC business for decades, these giants are seizing a position in the new market for liquid cooling.
