The lower end of described output backboard is provided with Plug Division.
The beneficial effects of the utility model are: the utility model comprises mainboard and exports backboard, described output backboard and described mainboard bridge joint, described mainboard comprises pcb board, electric capacity, transformer, fin and EMI inductance, described electric capacity, described transformer, described fin and described EMI inductance are all arranged at described pcb board, the quantity of described transformer is provided with at least two, and multiple described transformer carries out parallel connection.Power storage amount of the present utility model is large, easy to use, because multiple transformer carries out parallel connection, the efficiency of the utility model power output is improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of utility model.
Wherein: 1-mainboard, 2-exports backboard, 3-PCB plate, 4-electric capacity, 5-transformer, 6-fin, 7-EMI inductance, 8-inserting groove, 9-Plug Division, 10-high-voltage capacitance, 11-output capacitance, 12-heat radiator body, 13-" V " shape radiating part.
Embodiment
Below in conjunction with embodiment and Figure of description, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
As shown in Figure 1, a kind of supply unit, comprise mainboard 1 and export backboard 2, export backboard 2 to connect with mainboard Bridge 1, mainboard 1 comprises pcb board 3, electric capacity 4, transformer 5, fin 6 and EMI inductance 7, electric capacity 4, transformer 5, fin 6 and EMI inductance 7 are all arranged at pcb board 3, and the quantity of transformer 5 is provided with at least two, and multiple transformer 5 carries out parallel connection.The quantity of transformer 5 is set to two by present embodiment, and two transformers 5 carry out parallel connection.Suppose that transformer 5 power output is 1000W, be then the power output that a supply unit must provide 1000W in a conventional manner, such efficiency is not high; And the utility model is arranged on same pcb board 3 in parallel by two transformers 5, make them provide the power output of 500W respectively, be most effective point with the half of efficiency characteristic gross output, significantly can promote the efficiency of power output like this.
Preferably, pcb board 3 is provided with inserting groove 8, and the lower end exporting backboard 2 is provided with Plug Division 9, is connected with inserting groove 8 by Plug Division 9, thus realization output backboard 2 is firmly connected with pcb board 3.Inserting groove 8 is set to square structure, according to different technological requirements, inserting groove 8 can also be set to other structures, only need meet output backboard 2 and firmly be connected with pcb board 3.
Preferably, electric capacity 4 comprises high-voltage capacitance 10 and output capacitance 11, and high-voltage capacitance 10 and output capacitance 11 are all connected to pcb board 3.High-voltage capacitance 10121 refers to the electric capacity of more than 1kY, or the electric capacity of more than 10kY, and current high-voltage capacitance 10 is mainly divided into poly-third ethene electric capacity of higfh-tension ceramics electric capacity, high voltage thin film electric capacity, high pressure etc.The effect of output capacitance 11 is that filtering current ripples makes it to become the constant-current characteristics being smoothly tending towards direct current.
Preferably, fin 6 comprises heat radiator body 12 and is arranged at multiple " V " shape radiating part 13 at heat radiator body 12 top, and multiple " V " shape radiating part 13 is arranged side by side, and the setting of this spline structure is in order to better heat radiation.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned execution mode and revise.Therefore, the utility model is not limited to above-mentioned embodiment, and any apparent improvement of every those skilled in the art done by basis of the present utility model, replacement or modification all belong to protection range of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
