FIELD: refrigerating equipment.
SUBSTANCE: invention relates to the cooling device for the air in the switch cabinet internal space cooling. Cooling device (1) has internal circuit (2) for the cooled air (103) directing from the switch cabinet internal space (101) and hydrodynamically separated from the internal circuit (2) external circuit (3) for the ambient air (104) directing. In the first internal circuit (2) a heat exchanger (4) is located, and in the external circuit (3) is the second heat exchanger (5), between which the refrigerant (6) is circulating. Heat exchangers (4, 5) have the air transmission direction (x, y), along which heat exchangers (4, 5) are air permeable between the air intake side (4.1, 5.1) and the air discharge side (4.2, 5.2). At least in front of one of the heat exchangers (4, 5) on the air intake side (4.1, 5.1), the first air guide element (16) is located, extending at an angle of (β), constituting 5<β<45° relative to the intake side (4.1, 5.1), and forming the air duct (7) between it and the air intake side (4.1, 5.1), which narrows along the air intake side (4.1, 5.1) overall dimension (z).
EFFECT: cooling device improvement so, that it had the improved efficiency with at the same time smaller dimensions and effective protection against the condensation water unwanted transition into the switching cabinet internal space.
