Title: LIQUID-COOLING HEAT PIPE RADIATOR SYSTEM FOR CABINET SERVER AND CONTROL METHOD THEREFOR
Abstract:
A liquid-cooling heat pipe radiator system for a cabinet server and a control method therefor. The system comprises an indoor heat radiator unit (1), an intermediate heat exchanger unit (3), and an outdoor cooling unit (2). The indoor heat radiator unit (1) comprises several indoor heat radiator modules (4), each indoor heat radiator module (4) comprising one gas pipe header (5), one liquid pipe header (6), multiple server cabinets (7), and a plurality of heat pipe radiator units (9). The heat pipe radiator unit (9) comprises a first-stage heat pipe (9-1) and a second-stage heat pipe heat-absorbing end (9-2). The intermediate heat exchanger unit (3) comprises multiple intermediate heat exchangers (12). The outdoor cooling unit (2) comprises at least one cooling module (13, 14). The heat-absorbing end of the first-stage heat pipe (9-1) extends into the chassis of a server (8) and is tightly attached to a main heat-generating element, and the heat-dissipating end is provided outside the chassis of the server (8) and is pressed on and attached to the second-stage heat pipe heat-absorbing end (9-2). The second-stage heat pipe heat-absorbing end (9-2) absorbs heat, and transfers the heat to the outdoor cooling unit (2) through the intermediate heat exchangers (12) so as to discharge the heat out of the server (8). The server-level cooling method improves the heat transfer efficiency, while reducing the heat transfer resistance.
