Abstract

A rack-mount server system of a liquid cooling system, in which a heat-generating component such as CPU is cooled by a coolant, is composed of: a plurality of server modules with heat-generating components which are cooled by the circulating coolant; a coolant circulation path to which the server modules are connected in parallel and through which the coolant to cool the server modules is circulated; and a cooling unit connected in the middle of the coolant circulation path, the cooling unit circulating the coolant and cooling the coolant by radiating its heat to the outside air. Furthermore, a bypass route parallel to the server modules and going around the server modules is provided in the coolant circulation path, and the circulation quantity of the coolant is controlled in the bypass route. Alternatively, the flow quantity of the coolant is controlled in each of the server modules. In this manner, the cooling enough to ensure the reliability of a plurality of server modules mounted in the rack cabinet can be achieved.

Description

technical field [0001] The present invention relates to a cooling technique for a rack-mounted server system in which a plurality of computers are stacked, and particularly relates to an effective technique for applying a liquid cooling system in which a coolant is circulated. Background technique [0002] In recent years, the rack mount method has become the mainstream in the system configuration, storage, and installation of information processing devices such as servers. The so-called rack-mounting method is to layer and install devices with various functions in a rack cabinet formed according to specific specifications. The rack-mounting method has the ability to freely select and configure each device, and the flexibility and expandability of the system configuration are excellent. Advantages such as reducing the overall footprint of the system. [0003] In particular, in the server system, the 19-inch rack cabinet stipulated in the IEC standard (International Electric...
