RADIO ELECTRONIC EQUIPMENT CABINET Russian patent published in 2001 - IPC

FIELD: instrument cabinets of radio electronic equipment. SUBSTANCE: cabinet has a carrying casing formed by hollow upper and lower heat exchangers with an internal longitudinal ribbing and hollow side walls. The heat exchangers and side walls from within have longitudinal partitions, which divide their cavities into the respective ducts. Branch pipes with fans, whose quantity equals the number of ducts, are staggered on the upper ends of the side walls. Due to it air flow in the opposite directions is ensured in the adjacent ducts of the heat exchangers, and their temperature fields are equalized, which improves the conditions of heat removal from the modules. A multi-stage design of the cabinet enhances the density of equipment arrangement. To this end, hollow interstage floors-heat exchangers with an interval longitudinal two-sided ribbing and partitions dividing their cavities into the respective ducts are used. EFFECT: enhanced reliability and density of arrangement. 2 cl, 7 dwg
