A cooling electronic cabinet assembly includes a cabinet that has a plurality of storage compartments that is each defined within an interior of the cabinet to store an electronic device. The cabinet has a plurality of air holes each being integrated into the cabinet. A plurality of blowers is each coupled to the cabinet and each of the blowers is aligned with a respective air hole. Each of the blowers urges air in a first direction when the blowers are turned on to urge the air over the electronic devices in the cabinet for cooling the electronic devices. A plurality of filter housings is each coupled to the cabinet and each of the filter housings is aligned with a respective one of the air holes. A plurality of filters is each of the filters is removably insertable into a respective one of the filter housings to filter particles from the air is blown through the filters.

A thin, single-layer thermally conductive jacket surrounds a PCA. One or more living springs integrated in the jacket exert compressive force on PCA components where cooling is desired. The compressive force creates and maintains a thermal contact though which heat is conducted out of the PCA components and into the jacket. The jacket conducts the heat (either directly or indirectly) to a liquid-cooled cold plate configured as a cooling frame surrounding one or more of the jacketed PCAs. The jacket, optionally through intermediate thermal transfer devices such as heat spreaders or heat pipes, transfers heat from components on the PCA to the cooling frame. Liquid flowing through the cooling frame's internal channels convects the heat out of the electronic device. Turbulence encouraged by turbulence enhancing artifacts including bends and shape-changes along the internal channels increases the efficiency of the convection.

At a connection portion between a common duct penetrating in an arrangement direction through switchgears arranged in the arrangement direction inside an electrical room, and an exhaust duct via which the common duct and outside of the electrical room communicate with each other, an end of the common duct is bent inward to form a first exhaust duct joining portion, and an end of the exhaust duct is bent outward to form a common duct joining portion. In a state in which an outer surface of the first exhaust duct joining portion and an inner surface of the common duct joining portion are in contact with each other, the first exhaust duct joining portion and the common duct joining portion are fastened and fixed by two or more pairs of bolts and welding nuts.
