CHAMBER FOR EQUIPMENT Russian patent published in 2014 - IPC G12B15/02 F24F7/08 H02B1/56 H05K7/20 G06F1/20 

FIELD: heating, ventilation.

SUBSTANCE: invention relates to ventilation and temperature control in the chambers for electronic equipment, particularly to devices and methods for controlling the air flow in these chambers. The chamber (110) for equipment with temperature control comprises: an air inlet opening (113) with an air blower (228) for supplying air into the chamber from the external environment through the air inlet opening, creating the pressurised air in the chamber when it is turned on; an air outlet opening (150); an air duct (125) extending in the interior volume (115) of the chamber between the cabinet (121) with the equipment and the outlet opening; and exhaust fan (127) to force air through the cabinet and the air duct toward the outlet opening. At that the air duct comprises the means (240) of air bypass, connecting the internal volume of the chamber with an internal volume of the air duct, so that when the air blower is turned off the air moved using the exhaust fan recirculates within the internal volume of the chamber, and when the supply fan is turned on the air is discharged from the chamber through the air outlet opening.

EFFECT: improving the efficiency of cooling by directing heat generated by the electrical equipment in the room to the external environment, which reduces the power consumption and frequency of maintenance and costs for it.
