Described water cooler has two, two water cooler serial or parallel connections; The ring type magnetic core high frequency transformer is installed on one of them water cooler; The secondary output stage of ring type magnetic core high frequency transformer is connected with power device on being installed in water cooler, and ring type magnetic core high frequency transformer centre cap is connected with the output electrode of another water cooler, housing.
Described a kind of water cooling high power switching power supply, its special character is: be with a cooling jacket at ring type magnetic core high frequency transformer skin, the inside and outside surface coverage of cooling jacket and ring type magnetic core high frequency transformer welds together and liquid sealing, described cooling water is with one, and vertically pipe, annular pipe constitute, the annular pipe communicates with vertical pipe, have on the annular pipe into and on water interface, the vertical pipe water outlet interface is arranged, whole formation water-cooled high frequency transformer; Gapped between the annular pipe of the cooling jacket of water-cooled high frequency transformer and the ring type magnetic core high frequency transformer; The cooling jacket of water-cooled high frequency transformer and water cooler serial or parallel connection.
Described a kind of water cooling high power switching power supply, its special character is: two water-cooled high frequency transformers are arranged, behind the cooling jacket serial or parallel connection of two water-cooled high frequency transformers with the water cooler serial or parallel connection.
The utility model compared with prior art has following advantage: 1) cancelled the big fan at original forced air cooling top, dwindled volume, reduced operating noise; 2) power device is installed on the water cooler, and the heat that power device produces is discharged by the recirculated water in the water cooler, and the Inlet and outlet water joint is connected by the water inlet pipe on insulation tube connector and the housing, outlet pipe; So it not only insulate, can prevent electric leakage, and good heat dissipation effect, manufacturing and operating cost are low.
