Abstract: A data center cooling system has an indoor portion wherein heat is absorbed from components in the data center, and an outdoor heat exchanger portion wherein outside air is used to cool a first heat transfer fluid (e.g., water) present in at least the outdoor heat exchanger portion of the cooling system during a first mode. When an appropriate time has been reached to switch from the first mode to a second mode, the outdoor heat exchanger portion of the data cooling system is switched to a second heat transfer fluid, which is a relatively low performance heat transfer fluid (compared to the first fluid). It has a second heat transfer fluid freezing point, lower than the first heat transfer fluid freezing point, and sufficiently low to operate without freezing when the outdoor air temperature drops below a first predetermined relationship with the first heat transfer fluid freezing point.

Abstract: A data center cooling system is operated in a first mode; it has an indoor portion wherein heat is absorbed from components in the data center, and an outdoor heat exchanger portion wherein outside air is used to cool a first heat transfer fluid in at least the outdoor heat exchanger portion of the cooling system during the first mode. The first heat transfer fluid is a relatively high performance heat transfer fluid (as compared to the second fluid), and has a first heat transfer fluid freezing point. A determination is made that an appropriate time has been reached to switch from the first mode to a second mode. Based on this determination, the outdoor heat exchanger portion of the data cooling system is switched to a second heat transfer fluid, which is a relatively low performance heat transfer fluid, as compared to the first heat transfer fluid.

Abstract: A cooling system such as an intra-rack cooling system 500 of a data centre comprises: one or more nodes, such as servers 300, each node having at least one temperature sensor to monitor a temperature of the node components; an air-to-liquid heat exchanger 402 configured to accept a liquid coolant input, preferably via a first shut-off valve 504, to provide cooled air to the one or more nodes; and a temperature sensor to monitor a temperature of air Tai provided by the heat exchanger. The cooling system also comprises a direct liquid cooling apparatus to provide liquid coolant to components of the one or more nodes, preferably an inlet plenum 404, i.e. manifold, and an outlet plenum 406. The apparatus supplies cold input coolant 412, preferably via a second shut-off valve 506, to the one or more nodes and ejects warm coolant 410. A valve, ideally a three-way valve 502, is configured to control a proportion of the coolant flow directed to the heat exchanger and the one or more nodes based upon the monitored temperatures. A flow rate of coolant is also controlled based upon the monitored temperatures, preferably by varying the pump strength of a pump 401.

Abstract: Eine Kühlplattenvorrichtung umfasst Wände, welche ein aktives Volumen in Nachbarschaft zu einem Einlassplenum umgeben; die Wände umfassen eine Einlassöffnung an einem Ende einer Oberseite des Einlassplenums und eine Plenumöffnung zwischen dem Einlassplenum und dem aktiven Volumen. Ebenfalls umfasst ist ein Blockierelement, welches das Einlassplenum teilweise von dem aktiven Volumen trennt. Das Blockierelement ist strukturell dafür konfiguriert, vorzugsweise eine Strömung von dem Einlassplenum in das aktive Volumen umzuleiten.
