1. A switch cabinet arrangement comprising at least one IT rack or switch cabinet housing through which air is passed for cooling components accommodated in the IT rack or switch cabinet housing, comprising wherein an air-liquid heat exchanger circuit is charged by the air and a liquid passing through the air-liquid heat exchanger is heated; a liquid-liquid heat exchanger having fluid passing through it, the heated liquid from the air-liquid heat exchanger being coupled to the liquid-liquid heat exchanger, with the liquid passing through the liquid-liquid heat exchanger having a boiling point lower than the boiling point of the heated liquid from the air-liquid heat exchanger under standard conditions.
