  1. 1. Experimental and numerical study of the thermal and hydraulic effect of EMC screens in radio base stations : detailed and compact models

    Author : Raúl Antón Remírez; Björn Palm; Masud Behnia; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sub-rack; perforated plate; air cooling; 90 degrees turn; flow deistribution; CFD; measurement; Mechanical energy engineering; Mekanisk energiteknik;

    Abstract : Today’s telecommunication cabinets use Electro Magnetic Compliance (EMC) screens in order to reduce electromagnetic noise that can cause some miss functions in electronic equipment. Many radio base stations (RBSs) use a 90-degree building architecture: the flow inlet is perpendicular to the EMC screen, which creates a complex flow, with a 90-degree air turn, expansions, compressions, perforated plates and PCBs.

    Abstract : Hotels constitute one of the main, and still expanding, pillars of the tourism sector and are highly unique among other commercial buildings. Resource intensive and frequently inefficient systems and operational routines applied in the sector, result in considerable environmental impact and indicate an urgent need for more environmentally sound practices and products in the hotel industry.
