“CONSTRUCTION DEVICE INTRODUCED INTO AN ELECTRICAL POWER PLANT MODULE”, more specifically relating to an electrical power plant module (1) of the type used for accessibility to electrical energy, primarily in remote areas such as isolated rural communities, mining camps, oil platforms, areas recently affected by storms, areas affected by earthquakes, offshore platforms, etc., or areas undergoing conflict; the said power plant module (1) is supplied in the form of enclosures or containers (2) of the ISO maritime type and includes a structural container (2A) having a flat base (2b) upon which are installed structural columns (C1) and crossmembers (T2) for the mounting of plates (cp) that form the peripheral walls (2C) and the upper wall (2D) of the container (2A), with the end walls (2C1) of the container (2A) providing at least one cut-out area (2c2) for the installation of a tilting door (3) designed for the superolateral expulsion of hot air (AR) from the radiator (R); the said tilting door (3) is installed in the respective cut-out area (2c2) by means of hinged closures (4) or other articulated and/or tilting closures, which closures (4) in turn are secured to the lower edge (3a) of the door (3) in such a way that when the door (3) is tilted outward from the container, with an angulation (α), it forms a gas conduit (CG) in order to direct the air (AR) toward the superolateral portion of the structural container (2A): the tilting doors (3) that are installed in the extreme lateral portions (2C1) of the container (2A) are arranged in the substations (SB) of the power plant module (1) in such a way that they are aligned longitudinally with corresponding cooling units (UR) that are located on the inside and at the end in relation to the transformer/distribution unit (UT).
