Abstract:
1. A cooling system, configured to cool an orthogonal circuit board assembly in an orthogonal architecture, wherein the orthogonal circuit board assembly comprises one or more front circuit board which are orthogonally arranged in relation to one or more rear circuit board inside a cabinet, wherein: the orthogonal circuit board assembly comprises a backplane, the one or more front circuit board located in a front portion of the orthogonal circuit board assembly, and the one or more rear circuit board located in a rear portion of the orthogonal circuit board assembly, the one or more front circuit board is inserted on one surface of the backplane, the one or more rear circuit board is inserted on the other surface of the backplane, and the one or more rear circuit board and the one or more front circuit board are orthogonal to each other; wherein the cabinet comprises a front side, a back side opposite to the front side, two opposite lateral sides, a top side, and a bottom side opposite to the top side, an upper end of the orthogonal circuit board assembly is connected to the top side of the cabinet, a lower end of the orthogonal circuit board assembly is spaced apart from the bottom side of the cabinet, and the two lateral sides of the circuit board assembly are spaced apart from the two lateral sides of the cabinet; wherein the cooling system comprises: a first cooling air duct that allows first air flows from the front side of the cabinet corresponding to a region of the one or more front circuit board into the cabinet and flows throughout the front portion of the orthogonal circuit board assembly, wherein the first cooling air duct is substantially disposed in a central region of the front side of the cabinet which is spaced away from all four lateral sides of the cabinet, in order that first air flows from the central region of the front side be distributed towards both lateral sides of the one or more front circuit board, and be discharged out to first openings in the opposite back side, which are along both lateral sides of the cabinet; and a second cooling air duct which is either disposed above or below the first cooling duct in order that second air flows enter from the front side into the cabinet and travels vertically from one end towards another end of the one or more rear circuit board to be discharged out to second openings which are disposed on an opposite end away from the second air duct and in the back side of the cabinet.
