FIELD: heating.
SUBSTANCE: invention concerns heat exchanger (2) for water-cooled network cabinets and method of cooling for network cabinets, particularly for server cabinets. Heat exchanger is an air-to-water heat exchanger including two heat exchange elements (3, 4) with separate cooling water circuits (13, 14), for implementation of heat exchanger (2) with a number of additional elements. Partition (10) is positioned in the gap (5) between two heat exchange elements (3, 4) and can shift, so that in case of failure of one heat exchange element or one cooling circuit the respective heat exchange element is blocked by the partition in pneumatic way.
EFFECT: reliable operation of heat exchanger cooling network and server cabinets due to replacement of defective heat exchanger in case of failure of one out of two heat exchangers or of cooling water network, without interruption of operation process in general.
