Abstract
A cooling unit for cooling the air admitted to the interior of a switchgear cabinet (), which cooling unit has an inner circuit, through which the air to be cooled is routed from a switchgear cabinet interior, and an outer circuit () which is fluidically partitioned from the inner circuit and through which the surrounding air is routed, wherein the inner circuit contains a first heat exchanger and the outer circuit contains a second heat exchanger, between which a coolant is circulating, wherein the heat exchangers have an air flow direction along which the heat exchangers allow air to pass between an air inlet side and an air outlet side, characterized in that at least one of the heat exchangers has a first air guide upstream on the air inlet side, which extends at an angle with 5<β<45° relative to the air inlet side and forms an air duct between itself and the air inlet side, which tapers along a dimension of the air inlet side.
