COOLING STRUCTURE FOR COMPONENTS LOCATED IN THE INTERNAL SPACE OF ELECTRIC BOXES Russian patent published in 2017 - IPC H02B1/56 H05K7/20 

FIELD: electricity.

SUBSTANCE: in the electrical cabinet (1) with the cooling unit (2), which has a first closed circulation circuit (3) of the coolant and a second closed circulation circuit (4) of the coolant hydraulically separated from it, the first closed cooling circuit (3) of refrigerating machine or a water cooling unit, and the second closed circulating coolant circuit (4) has an evaporation-condensation structure.

EFFECT: creation of a control cabinet with a cooling device in which the cooling apparatus can be formed by simple technical means and even at low temperature differences between the set temperature of the electrical cabinet and the ambient temperature of the electrical cabinet can be operated passively, ie without the use of a chiller or a water cooling unit.
