Abstract
A cooling arrangement for autonomous cooling of a rack hosting components and fans comprises a closed loop and an open loop. Liquid cooling is used in the closed loop to transfer heat from heat-generating units of the components to a primary side of a liquid-to-liquid heat exchanger. An air-to-liquid cooling unit is used in the open loop to absorb heat expelled from the rack by the fans. A liquid from a cold supply line is first heated to some degree in the air-to-liquid cooling unit before reaching a secondary side of the liquid-to-liquid heat exchanger. The primary side being hotter than the secondary side, heat is transferred from the primary side to the secondary side of the liquid-to-liquid heat exchanger. The liquid is expelled at a higher temperature from the secondary side to a hot return line.
