A compact air-cooling device for a closed technical cabinet comprises a housing (18), an evaporator (30), a condenser (32), a compressor (34), a primary fan (42) and secondary fan (44). Partition elements (36, 56, 58, 60) define a primary air circuit, which allows mechanical cooling in a closed loop with air from the inside (14) of the closed technical cabinet, and a secondary air circuit, which allows to cool the condenser (32) with air from the outside (14) of the closed technical cabinet. These partition elements (36, 56, 58, 60) include movable elements (58, 60) that can be brought into an auxiliary position, so that the secondary air circuit is in communication with the primary air circuit upstream of the evaporator (30), and the inside air intake chamber (52) is sealed off from the primary air circuit and is in direct communication with the outside environment of the closed technical cabinet. <IMAGE> |
