Switchgear cabinet for use in e.g. refrigerator, has air-air heat exchanger that includes two sections which are thermally coupled to air-air heat exchanger, for heat exchange

摘要

The cabinet has a cooling device that includes an air-air heat exchanger (6) having a section (6.1) arranged in an ambient air passage and a section (6.2) arranged in a purified air passage. The sections of the air-air heat exchanger are arranged vertically spaced from each other, and are thermally coupled. A closed duct system (7) partially filled with a coolant is arranged between the sections of the air-air heat exchanger. The sections are thermally coupled to the air-air heat exchanger, for heat exchange.
