Abstract: A rectifier bridge assembly includes a rectifier bridge circuit adapted to connect to at least one alternating current source with at least two diode compartments operatively connected to the rectifier bridge circuit and a direct current output to convert alternating current into direct current. A heat sink is formed with at least two apertures for receiving the at least two diode compartments in spaced apart relation and in substantial contact with the heat sink, wherein heat from the diode compartments is evenly dispersed to the heat sink.

Abstract: A hard disk storage device for industrial computers, comprising a casing, a fixed storage rack, a movable storage rack, a fixed rack, a frame lid, an elastic plate and a support rack; the elastic plate is utilized such that the movable storage rack is lifted as the hard disk storage device is opened, and the support rack is utilized for confining the lifting height of the movable storage rack, such that the content capacity of the storage device is increased by effective use of limited spaces.
