Abstract: A power distribution device for connection with a plurality of power supply units includes a signal control element, a transmission mechanism including a current transmission unit and a ground transmission unit, and a plurality of electrical connectors respectively adapted for insertion of and connection with the power supply units. Each electrical connector includes a first conductive terminals electrically connected to the signal control element for transmitting an electrical signal to the signal control element, and a plurality of second conductive terminals electrically connected to the current and ground transmission units for transmitting current to the current and ground transmission units.

Abstract: An electrical connector includes an insulating body having a bottom surface, a receiving groove formed in the bottom surface, and at least one support block projecting downwardly from the bottom surface for connection with a circuit board and cooperating with the bottom surface to define a venting space that communicates with the receiving groove and a solder hole in the circuit board. A conductive terminal includes a first positioning portion extending into and positioned in the receiving groove, and a second positioning portion connected to the first positioning portion and extending through the venting space and adapted to be positioned in the solder hole.

Abstract: An improved structure of cooling tower includes a fan housing with a fan disposed therein, induction openings distributed on the fan housing and located below the fan, and a diffuser stack disposed at one end surface of the fan housing. In operation, cold air is drawn into the cooling tower by the fan through inlet openings of the cooling tower so as to exchange heat with the condensing water within a water chiller. When warm and wet air is drawn out of the cooling tower and the warm and wet air outside the cooling tower is induced in through the induction openings and then is drawn out, circulation reflux of warm and wet air, which tends to occur in conventional cooling towers, can be avoided and therefore increase the efficiency of the water chiller.
